The Falcon: Water Crossings & Hazards

/by

Part of the Falcon Public EIA Project

In this section of the Falcon Public EIA Project, we explore the hydrological and geological conditions of the pipeline’s construction areas. We first identify the many streams, wetlands, and ponds the Falcon must cross, as well as describe techniques Shell will likely use in these water crossings. The second segment of this section highlights how the areas in the Falcon’s path are known for their complex geological features, such as porous karst limestone and shallow water tables that can complicate construction.

Quick Falcon Facts

  • Intersects 319 streams; 361 additional streams located only 500ft from construction areas
  • Intersects 174 wetlands; 470 additional wetlands located only 500ft from construction areas
  • Majority of crossings will be open cuts and dry-ditch trenching
  • A total of 19 horizontal directional drilling (HDD) sites; 40 conventional boring sites
  • 25 miles of pipeline overlap karst limestone formations, including 9 HDD sites
  • 240 groundwater wells within 1/4 mile of the pipeline; 24 within 1,000ft of an HDD site

Defining Water Bodies

The parts of Pennsylvania, West Virginia, and Ohio where the Falcon pipeline will be built lie within the Ohio River Basin. This landscape contains thousands of streams, wetlands, and lakes, making it one of the most water rich regions in the United States. Pipeline operators are required to identify waters likely to be impacted by their project. This two-step process involves first mapping out waters provided by the U.S. Geological Survey’s national hydrological dataset. Detailed field surveys are then conducted in order to locate additional waters that may not yet be accounted for. Many of the streams and wetlands we see in our backyards are not represented in the national dataset because conditions can change on the ground over time. Yet, plans for crossing these must also be present in pipeline operator’s permit applications.

Streams

Streams (and rivers) have three general classifications. “Perennial” streams flow year-round, are typically supplied by smaller up-stream headwaters, and are supplemented by groundwater. In a sense, the Ohio River would be the ultimate perennial stream of the region as all smaller and larger streams eventually end up there. “Intermittent” streams flow for only a portion of the year and are dry at times, such as during the summer when water tables are low. Finally, “ephemeral” streams flow only during precipitation events.

These classifications are important because they can determine the extent of aquatic habitat that streams can support. Working in streams that have no dry period can put aquatic lifeforms at elevated risk. For this and other reasons, many states further designate streams based on their aquatic life “use” and water quality. In Pennsylvania, for instance, the PA DEP uses the designations: Warm Water Fishes (WWF), Trout Stocked (TSF), Cold Water Fisheries (CWF) and Migratory Fishes (MF). Streams with exceptional water quality may receive an additional designation of High Quality Waters (HQ) and Exceptional Value Waters (EV).

Wetlands

Similar to streams, wetlands also have unique designations. These are based on the U.S. Fish and Wildlife Services’ national wetlands inventory. Wetlands are generally defined as “lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow water.” As such, wetlands are categorized by their location (such as a tidal estuary or an inland wetland that lacks flowing water), its substrate (bedrock, sand, etc.), and plant life that might be present. While there are hundreds of such categories, only four pertain to the wetlands present in the regions where the Falcon pipeline will be built. Their designations roughly translate to the following:

  • Palustrine Emergent (PEM): Marshes and wet meadows hosting perennial small trees, shrubs, mosses, or lichens
  • Palustrine Shrub (PSS): Similar to PEMs, but characterized by also having well-established shrubs
  • Palustrine Forested (PFO): Similar to PEMs and PSSs, but having trees larger than 6 meters high
  • Palustrine Unconsolidated Bottom (PUB) and Palustrine Opem Water (POW) (aka ponds)

Pipeline operators are required to report the crossing length of each wetland they will encounter, as well as the area of permanent and temporary disturbance that would occur in each of these wetlands. When building the pipeline, operators are required to ensure that all measures are taken to protect wetlands by minimizing impacts to plant life, as well as by taking “upland protective measures” to prevent sedimentation runoff during precipitation events. When undergoing FERC EIA scrutiny, operators are also required to limit the width of wetland construction areas to 75 feet or less.

Crossing Methods

Open-Cut Trenching

Pipeline operators use a variety of methods when crossing streams, wetlands, and ponds. Shorter length crossings often employ a rudimentary trench. After the cuts, construction crews attempts to repair damage done in the process of laying the pipeline. For longer crossings, operators can use boring techniques to go underneath water features.

Open-cut trenching

There are two general types of trenches. The first, “open-cut” crossings, are typically used for smaller waterbodies, such as in intermittent streams where flow may not be present during time of construction, or when construction can be completed in a short period of time (typically 24-48 hours). In this process, a trench is laid through the water body without other provisions in place.

The second type, “dry-ditch” crossing, are required by FERC for waterbodies up to 30 feet wide “that are state-designated as either coldwater or significant coolwater or warmwater fisheries, or federally-designated as critical habitat.” In these spaces, pumps are used to transfer stream flow around the area where trenching occurs. In places where sensitive species are present, dry-ditches must include a flume to allow these species to pass through the work area.

Conventional Boring

Conventional boring consists of creating a tunnel for the pipeline to be installed below roads, waterbodies, and other sensitive resources. Bore pits are excavated on either sides of the site. A boring machine is then used to tunnel under the resource and the pipeline is pushed through the bore hole.

Horizontal Directional Drilling

In more difficult or lengthy crossings, operators may choose to bore under a water feature, road, or neighborhood. Horizontal directional drilling (HDD) involves constructing large staging areas on either side of the crossing. A large drill bit is piloted through the ground along with thousands of gallons of water and bentonite clay for lubricant (commonly referred to as drilling muds). HDDs are designed to protect sensitive areas, but operators prefer not to use them as HDDs can be expensive and require in-depth planning in order for things to go well.

An example of what happens when things are rushed can be seen in Sunoco’s Mariner East 2 pipeline. The PA DEP has cited Sunoco for over 130 inadvertent returns (accidental releases of drilling muds) since construction began. These spills led to damaged water wells and heavy sedimentation in protected streams, as exemplified in the image above. Making matters worse, Sunoco later violated terms of a settlement that required them to re-survey before recommencing construction. See FracTracker’s article on these spills.

Footprint of the Falcon

The overwhelming majority of Falcon’s water body crossings will be executed with either open-cut or dry-ditch methods. There are 40 locations where conventional boring will be used, but only a 3 are used for crossing water resources. Shell intends to use 19 HDDs and, of these, only 13 are used for crossing water bodies of some kind (the longest of which crosses the Ohio River). All other conventional and HDD boring locations will be used to cross under roads and built structures. This is not entirely unusual for pipelines. However, we noted a number of locations where one would expect to see HDDs but did not, such as in the headwaters of the Ambridge and Tappen Reservoirs, as was seen in the images above.

Stream Impacts

Shell identified and/or surveyed a total of 993 stream sections in planning for the Falcon’s construction. As shown on FracTracker’s map, the pipeline’s workspace and access roads will directly intersect 319 of these streams with the following classifications: perennial (96), ephemeral (79), and intermittent (114). An additional 361 streams are located only 500ft from construction areas.

A number of these streams have special designations assigned by state agencies. For instance, in Pennsylvania, we found 10 stream segments listed as Trout Stocked (TS), which are shown on our interactive map.

Crossing HQ headwater streams of the Ambridge Reservoir

Perhaps more concerning, the Falcon will cross tributaries to the Service Creek watershed 13 times. These feed into three High Quality Cold Water Fishes (HQ/CWF) headwater streams of the Ambridge Reservoir in Beaver County, PA, shown in the image above. They also support the endangered Southern Redbelly Dace (discussed in greater depth here). On the eastern edge of the watershed, the Falcon will cross the raw water line leading out of the reservoir.

The reservoir supplies 6.5 million gallons of water a day to five townships in Beaver County (Ambridge, Baden, Economy, Harmony, and New Sewickley) and four townships in Allegheny County (Leet, Leetsdale, Bell Acres & Edgeworth). This includes drinking water services to 30,000 people.

We found a similar concern in Ohio where the Falcon will cross protected headwaters in the Tappan Reservoir watershed at six different locations. The Tappan is the primary drinking water source for residents in Scio. Below is a page from Shell’s permit applications to the PA DEP outlining the crossing of one of the Ambridge Reservoir’s CWF/HQ headwater streams.

Wetland Impacts

Shell identified a total of 682 wetland features relevant to Falcon’s construction, as well as 6 ponds. Of these, the pipeline’s workspace and access roads will directly intersect 174 wetlands with the following classifications: PEM (141), PSS (13), PFO (7), PUB (10), POW (3). An additional 470 of these wetlands, plus the 6 ponds, are located only 500ft from construction areas.

Example 1: Lower Raccoon Creek

A few wetland locations stand out as problematic in Shell’s construction plans. For instance, wetlands that drain into Raccoon Creek in Beaver County will be particularly vulnerable in two locations. The first is in Potter Township, where the Falcon will run along a wooded ridge populated by half a dozen perennial and intermittent streams that lead directly to a wetland of approximately 14 acres in size, seen below. Complicating erosion control further, Shell’s survey data shows that this ridge is susceptible to landslides, shown in the first map below in dotted red.

Landslide areas along Raccoon Creek wetlands and streams

This area is also characterized by the USGS as having a “high hazard” area for soil erosion, as seen in this second image. Shell’s engineers referenced this soil data in selecting their route. The erosion hazard status within 1/4 mile of the Falcon is a layer on our map and can be activated in the full-screen version.

High erosion hazard zones along Raccoon Creek

Shell’s permit applications to the PA DEP requires plans be submitted for erosion and sedimentation control of all areas along the Falcon route. Below are the pages that pertain to these high hazard areas.

Example 2: Independence Marsh

The other wetland area of concern along Raccoon Creek is found in Independence Township. Here, the Falcon will go under the Creek using horizontal drilling (highlighted in bright green), a process discussed in the next section. Nevertheless, the workspace needed to execute the crossing is within the designated wetland itself. An additional 15 acres of wetland lie only 300ft east of the crossing but are not accounted for in Shell’s data.

This unidentified wetland is called Independence Marsh, considered the crown jewel of the Independence Conservancy’s watershed stewardship program. Furthermore, the marsh and the property where the HDD will be executed are owned by the Beaver County Conservation District, meaning that the CCD signed an easement with Shell to cross publicly-owned land.

Groundwater Hazards

The Falcon’s HDD locations offer a few disturbing similarities to what caused the Mariner East pipeline spills. Many of Sunoco’s failures were due to inadequately conducted (or absent) geophysical surveys prior to drilling that failed to identify karst limestone formations and shallow groundwater tables, which then led to drilling muds entering nearby streams and groundwater wells.

Karst Limestone

Karst landscapes are known for containing sinkholes, caves, springs, and surface water streams that weave in and out of underground tunnels. Limestone formations are where we are most likely to see karst landscapes along the Falcon’s route.

In fact, more than 25 of the Falcon’s 97 pipeline miles will be laid within karst landscapes, including 9 HDD sites. However, only three of these HDDs sites are identified in Shell’s data as candidates for potential geophysical survey areas. The fact that the geology of the other 10 HDD sites will not be investigated is a concern.

One site where a geophysical survey is planned can be seen in the image below where the Falcon crosses under PA Highway 576. Note that this image shows a “geological formations” layer (with limestone in green). This layer shows the formation types within 1/4 mile of the Falcon and can activated in the full-screen version of our interactive map.

Water Tables

We also assessed the Falcon’s HDDs relative to the groundwater depths and nearby private groundwater wells. The USGS maintains information on minimum water table depths at different times of the year. In the image below we see the optional “water table depth” layer activated on the FracTracker map. The groundwater at this HDD site averages 20ft on its western side and only 8ft deep on the eastern side.

Shallow groundwater and private wells near a planned HDD site

Groundwater Wells

Also seen in the above image is the “groundwater wells” layer from the FracTracker map. We found 240 private water wells within 1/4 mile of the Falcon. This data is maintained by the PA Department of Natural Resources as well as by the Ohio Department of Natural Resources. Comparable GIS data for West Virginia were not readily available thus not shown on our map.

While all of these wells should be assessed for their level of risk with pipeline construction, the subset of wells nearest to HDD sites deserve particular attention. In fact, Shell’s data highlights 24 wells that are within 1,000 feet of a proposed HDD site. We’ve isolated the groundwater wells and HDD sites in a standalone map for closer inspection below. The 24 most at-risk wells are circled in blue.

The Falcon: Class Locations, Buildings & Recreational Areas

/by

Part of the Falcon Public EIA Project

In this segment of the Falcon Public EIA Project we begin to explore the different ways that pipelines are assessed for potential risk to populated areas. We outline a methods dictated by the Pipeline and Hazardous Materials Safety Administration (PHMSA) called Class Locations. This methods identifies occupied structures in proximity to a pipeline.

Quick Falcon Facts

  • 67% of the Falcon route will qualify as Class 1, 27% as Class 2, and 3% as Class 3.
  • More than 557 single family residences and 20 businesses within 660ft of the pipeline.
  • Three recreational parks and a planned luxury housing development also at risk.

Map of Falcon Class Locations

The following map will serve as our guide in breaking down the Falcon’s Class Locations. Expand the map full-screen to explore its contents in greater depth. Some layers only become visible as you zoom in. A number of additional layers are not shown by default, but can be turned on in the “layers” tab. Click the “details” tab in full-screen mode to read how the different layers were created.

Pipeline Class Locations

Pipeline “Class locations” determine certain aspects of how a pipeline is constructed. Essentially, a pipeline’s route is segmented into lengths that are each given different classifications as outlined in PHMSA guidelines. In general terms, a segment’s Class is established by first calculating a buffer that extends 220 yards (660ft) on either side of the pipeline’s center in 1-mile continuous lengths. This buffer area is then analyzed for how many building structures are present. Classes are then assigned to each 1-mile segment using the follow criteria:

  • Class 1: a segment with 10 or fewer buildings intended for human occupancy
  • Class 2: a segment with more than 10, but less than 46 buildings intended for human occupancy
  • Class 3: a segment with 46 or more buildings intended for human occupancy, or where the pipeline lies within 100 yards of any building, or small well-defined outside area occupied by 20 or more people on at least 5 days a week for 10 weeks in any 12-month period (i.e. schools, businesses, recreation areas, churches)
  • Class 4: a segment where buildings with four or more stories aboveground are prevalent

The finer details of these calculations and their adjustments are complex, however. For instance, Class locations can be shortened to less than 1-mile lengths if building densities change dramatically in an certain area. The example image below shows one of the ways available to operators for doing this, called the “continuous sliding” method:

Calculating Class Locations
(source: PHMSA)

Class location designations may also be adjusted over time as densities change. For instance, if new homes were built in proximity to a previously constructed pipeline, the operator may be required to reduce their operating pressure, strengthen the pipeline, or conduct pressure tests to ensure the segment would technically meet the requirements of a higher Class. Alternatively, operators can apply for a special permit to avoid such changes.

What Class Locations Dictate

Pipeline segments with higher Classes must meet more rigorous safety standards, which are enforced either by PHMSA or by their state equivalent, such as the Pennsylvania Utility Commission. These include:

  • Soil depth: Class 1 locations must be installed with a minimum soil depth of 30 inches (18 inches in consolidated rock). Class 2, 3, and 4 locations require a minimum soil depth of 36 inches (24 inches in consolidated rock)
  • Shut-off valves: Class locations determine the maximum distance from shut-off valves to populated areas, as follows: Class 1 (10 miles), Class 2 (7.5 miles), Class 3 (4 miles), and Class 4 (2.5 miles).
  • Operating pressure: Classes also regulate the maximum allowable operating pressure (MAOP) of pipeline segments
  • Structural integrity: Classes determine where thicker walled materials must be used to withstand higher pressures, as well as different structural testing methods used in safety inspections

By replicating the 600 foot buffer from the Falcon’s centerline (used as the standard distance for determining Class Locations) we found that 67% of the Falcon route will qualify as Class 1, 27% as Class 2, and 3% as Class 3. These are represented on our interactive maps as green, yellow, and orange segments, respectively. An additional segment is marked as having an “unknown” Class on our maps (shaded in gray). This is the stretch crossing the Ohio River, where Shell’s Class location analysis has not been updated to reflect the route change that occurred in the summer of 2017.

Residential Structures

In total, there are 557 single family residences, 20 businesses, and a church within the 660ft buffer. Shell’s data also identify non-occupied structures along the route, such as sheds, garages, and other outbuildings. There are 535 such structures, but we did not have the time to replicate the locations of these sites. It is also important to note that the points on our interactive map represent only those identified by Shell, which we believe is an incomplete assessment of occupied structures based on our quick review of satellite maps.

Three residential structures lie directly within the 50-foot right-of-way. One of these homes, located in a Class 2 segment in Independence Township, is shown below. The Falcon will come as close as 20 feet to the edge of the structure and surround the home on three sides.

An occupied residence in the right-of-way

Neighborhoods in the following five communities account for the entirety of Falcon’s Class 3 locations. These would be considered the most “at risk” areas along the route in terms of proximity to the number of occupied structures. For instance, below is a satellite view of the Class 3 section of Raccoon Township.

  • Rumley Township, Harrison OH
  • Knox Township, Jefferson County OH
  • Raccoon Township, Beaver County PA
  • Independence Township, Beaver County PA
  • Mount Pleasant Township, Washington County PA

Recreational Areas

In the above image we also see the location of Raccoon Township Municipal Park (in purple), home to a number of ballfields. Two similar recreation areas are located in the 660ft Class Location buffer: Mill Creek Ballpark, in Beaver County PA, and Clinton Community Park, in Allegheny County PA.

However, the Raccoon Township park is notable in that the Falcon cuts directly through its property boundary. Shell intends to bore under the park using HDD techniques, as stated in their permit applications, “to avoid disturbance to Beaver County baseball field/recreational park,” also stating that, “this HDD may be removed if the recreational group will allow laying the pipeline along the entrance roadway.”

New Housing Developments

One discovery worth attention is that the Falcon runs straight through an under-construction luxury housing development. Located in Allegheny County, PA, its developer, Maronda Homes, bills this growing community as having “picturesque landscapes, waterfront views and a peaceful collection of homes.” Shell mentions this development in their permit applications, stating:

Maronda Homes is in the planning and design stage of a very large housing development and SPLC [Shell Pipeline LC] worked closely with the developer and the Project was rerouted to avoid most of the housing sites.

It stands to reason that this neighborhood will eventually rank as one of the densest Class 3 areas along the Falcon route. Whether or not the pipeline is updated with higher safety standards as a result remains to be seen. The image below illustrates where the Falcon will go relative to lots marked for new homes. This property lots diagram was obtained from Shell’s GIS data layer and can be viewed on the FracTracker interactive map as well.

The Falcon intersects a luxury home development

1/31/18 Note: the Pittsburg Post-Gazette obtained newer lot line records for a portion of the Maronda Farms during their investigation into this story. These new records appear to have some alterations to the development, as seen below.

Maronda Farms, updated lot lines

Issues with Setbacks

There are no setback restrictions for building new homes in proximity to a pipeline. Parcels will eventually be sectioned off and sold to home buyers, begging the question of whether or not people in this community will realize a hazardous liquid pipeline runs past their driveways and backyards. This is a dilemma that residents in a similar development in Firestone, Colorado, are now grappling with following a recent pipeline explosion that killed two people, seen below, due to inadequate building setbacks.

Interestingly, we researched these same Maronda Farms parcels in FracTracker’s Allegheny County Lease Mapping Project only to discover that Maronda Homes also auctioned off their mineral rights for future oil and gas drilling. New homeowners would become victims of split-estate, where drilling companies can explore for oil and gas without having to seek permission from property owners, amplifying their level of risk.

The Falcon: High Consequence Areas & Potential Impact Zones

/by

Part of the Falcon Public EIA Project

In this segment of the Falcon Public EIA Project we continue to explore the different ways that pipelines are assessed for potential risk – in this case, relative to population centers, drinking water systems, and sensitive habitats. We outline methods dictated by the Pipeline and Hazardous Materials Safety Administration (PHMSA) called “high consequence areas” (HCAs) and how they determine potential impact zones for highly volatile liquid (HVL) pipelines. These methods are then applied to the Falcon to understand its possible dangers.

Quick Falcon Facts

  • An estimated 940-foot potential impact radius (PIR)
  • 60 of 97 pipeline miles qualifying as High Consequence Areas (HCA)
  • More than 8,700 people living in the “vapor zone”
  • 5 schools, 6 daycare centers, and 16 emergency response centers in “vapor zone”
  • In proximity to 8 source-water (drinking water) protection areas
  • Affecting habitats populated by 11 endangered, protected, or threatened species

Map of Falcon High Consequence Areas

The following map will serve as our guide in breaking down the Falcon’s High Consequence Areas. Expand the map full-screen to explore its contents in greater depth. Some layers only become visible as you zoom in. A number of additional layers are not shown by default, but can be turned on in the “layers” tab. Click the “details” tab in full-screen mode to read how the different layers were created.

View Map Fullscreen | How FracTracker Maps Work

High Consequence Areas

While Class Locations, discussed in a prior project article, dictate the construction and maintenance of a pipeline, high consequence areas (HCAs) designate when operators must implement integrity management programs (IMP) where pipeline failures could cause major impacts to populated areas, as well as drinking water systems and ecological resources — otherwise defined as unusually sensitive areas (USAs).

Populated Areas

Two considerations are used when determining pipeline proximity to population centers:

  1. High Population Areas – an urbanized area delineated by the Census Bureau as having 50,000 or more people and a population density of at least 1,000 people per square mile; and
  2. Other Populated Areas – a Census Bureau designated “place” that contains a concentrated population, such as an incorporated or unincorporated city, town, village, or other designated residential or commercial area – including work camps.

USAs: Drinking Water

PHMSA’s definition of drinking water sources include things such as:

  • Community Water Systems (CWS) – serving at least 15 service connections and at least 25 year-round residents
  • Non-transient Non-community Water Systems (NTNCWS) – schools, businesses, and hospitals with their own water supplies
  • Source Water Protection Areas (SWPA) for a CWS or a NTNCWS
  • Wellhead Protection Areas (WHPA)
  • Sole-source karst aquifer recharge areas

These locations are typically supplied by regulatory agencies in individual states.

With the exception of sole-source aquifers, drinking water sources are only considered if they lack an alternative water source. However, PHMSA is strict on what alternative source means, stating that they must be immediately usable, of minimal financial impact, with equal water quality, and capable of supporting communities for at least one month for a surface water sources of water and at least six months for a groundwater sources.

One very important note in all of these “drinking water” USA designations is that they do not include privately owned groundwater wells used by residences or businesses.

USAs: Ecological Resource

Ecological resource areas are established based on any number of qualities with different variations. In general terms, they contain imperiled, threatened, or endangered aquatic or terrestrial species; are known to have a concentration of migratory waterbirds; or are a “multi-species assemblage” area (where three or more of the above species can be found).

Calculating HCAs

Like Class locations, HCAs are calculated based on proximity. The first step in this process is to determine the pipeline’s Potential Impact Radius (PIR) — the distance beyond which a person standing outdoors in the vicinity of a pipeline rupture and fire would have a 99% chance of survival; or in which death, injury, or significant property damage could occur. PIR is calculated based on the pipeline’s maximum allowable operating pressure (MAOP), diameter, and the type of gas. An example of this calculation is demonstrated in FracTracker’s recent article on the Mariner East 2 pipeline’s PIR.

Once the PIR is known, operators then determine HCAs in one of two ways, illustrated in the image below:

  • Method 1: A Class 3 or Class 4 location, or a Class 1 or Class 2 location where “the potential impact radius is greater than 660 feet (200 meters), and the area within a potential impact circle contains 20 or more buildings intended for human occupancy”; or a Class 1 or Class 2 location where “the potential impact circle contains an “identified site.”
  • Method 2: An area within PIR containing an “identified site” or 20 or more buildings intended for human occupancy.

Calculating HCAs
(source: PHMSA)

In these definitions, “identified sites” include such things as playgrounds, recreational facilities, stadiums, churches, office buildings, community centers, hospitals, prisons, schools, and assisted-living facilities. However, there is a notable difference in how HCAs are calculated for natural gas pipelines vs. hazardous liquid pipelines.

Beyond just looking at what lies within the PIR, pipelines that contain gasses such as ethane potentially impact a much broader area as vapors flow over land or within a river, stream, lake, or other means. A truly accurate HCA analysis for an ethane pipeline leak requires extensive atmospheric modeling for likely vapor dispersions, such as seen in the example image below (part of a recent ESRI GIS conference presentation).

Vapor dispersion modelling
(source: TRC Solutions)

 

What HCAs Dictate

HCAs determine if a pipeline segment is included in an operator’s integrity management program (IMP) overseen by PHMSA or its state equivalent. IMPs must include risk assessments that identify the most likely impact scenarios in each HCA, enhanced management and repair schedules, as well as mitigation procedures in the event of an accident. Some IMPs also include the addition of automatic shut-off valves and leak detection systems, as well as coordination plans with local first responders.

The Falcon Risk Zones

Shell’s permit applications to the PA DEP state the pipeline:

…is not located in or within 100 feet of a national, state, or local park, forest, or recreation area. It is not located in or within 100 feet of a national natural landmark, national wildlife refuge, or federal, state, local or private wildlife or plant sanctuaries, state game lands. It is also not located in or within 100 feet of a national wild or scenic river, the Commonwealth’s Scenic Rivers System, or any areas designated as a Federal Wilderness Area. Additionally, there are no public water supplies located within the Project vicinity.

This is a partial truth, as “site” and “vicinity” are vague terms here. A number of these notable areas are within the PIR and HCA zones. Let’s take a closer look.

The PIR (or “Blast Zone”)

Shell’s permit applications state a number of different pipeline dimensions will be used throughout the project. Most of the Falcon will be built with 12-inch steel pipe, with two exceptions: 1) The segment running from the Cadiz, OH, separator facility to its junction with line running from Scio, OH, will be a 10-inch diameter pipe; 2) 16-inch diameter pipe will be used from the junction of the Falcon’s two main legs located four miles south of Monaca, PA, to its end destination at the ethane cracker. We also know from comments made by Shell in public presentations that the Falcon’s maximum allowable operating pressure (MOAP) will be 1,440 psi. These numbers allow us to calculate the Falcon’s PIR which, for a 16″ ethane pipeline at 1,440psi, is about 940 feet. We’ve termed this the “blast zone” on our maps.

The HCA (or “Vapor Zone”)

Shell’s analysis uses an HCA impact radius of 1.25 miles. This much larger buffer reflects the fact that vapors from hazardous liquid pipelines can travel unpredictably at high concentrations for long distances before ignition. This expanded buffer might be called the “vapor zone,” a term we used on our map. Within the HCA “vapor zone” we find that 60 of the Falcon’s 97 miles qualify as high consequence areas, with 35 miles triggered due to their proximity to drinking water sources, 25 miles trigger for proximity to populated areas, and 3 miles for proximity to ecological areas.

Populated Areas

Shell’s HCA buffer intersects 14 US Census-designated populated areas, shown in the table below. Falcon’s right-of-way directly intersects two of these areas: Cadiz Village in Harrison County, Ohio, and Southview CDP (Census Designated Place) in Washington County, PA. These areas are listed below. Additionally, we included on the FracTracker map the locations of public facilities that were found inside the HCA buffer. These include 5 public schools, 6 daycare centers, 10 fire stations, and 6 EMS stations.

Area Population State HCA
Pittsburgh Urbanized Area High PA Indirect
Weirton-Steubenville Urbanized Area High WV/OH/PA Indirect
Scio Village Other OH Indirect
Cadiz Village* Other OH Direct
Amsterdam Village Other OH Indirect
Shippingport Borough Other PA Indirect

Hookstown Borough Other PA Indirect
Midway Borough Other PA Indirect
Clinton CDP Other PA Indirect
Imperial CDP Other PA Indirect
Southview CDP* Other PA Direct
Hickory CDP Other PA Indirect
Westland CDP Other PA Indirect
* Indicates an area the Falcon’s right-of-way will directly intersect

While it is difficult to determine the actual number of people living in the PIR and HCA vapor zone, there are ways one can estimate populations. In order to calculate the number of people who may live within the HCA and PIR zones, we first identified U.S. Census blocks that intersect each respective buffer. Second, we calculated the percentage of that census block’s area that lies within each buffer. Finally, we used the ratio of the two to determine the percentage of the block’s population that lies within the buffer.

Based on 2010 Census data, we estimate that 2,499 people live within a reasonable projection of the Falcon’s PIR blast zone. When expanded to the HCA vapor zone, this total increases to 8,738 people. These numbers are relatively small compared to some pipelines due to the fact that a significant portion of the Falcon runs through fairly rural areas in most places.

Drinking Water Sources

Shell’s data identified a number of drinking water features considered in their HCA analysis. Metadata for this information show these sites were obtained from the Ohio Division of Drinking and Ground Waters, the West Virginia Source Water Assessment and Wellhead Protection Program, and the Pennsylvania DEP Wellhead Protection Program. The exact locations of public drinking water wells and intake points are generally protected by states for safety reasons. However, we duplicated the 5-mile buffer zones used on Shell’s map around these points, presumably denoting the boundaries of source water protection areas, wellhead protection areas, or intake points.

Drinking water buffers in Shell’s HCA analysis

As shown on FracTracker’s interactive map, five of these areas serve communities in the northern portions of Beaver County, shown in the image above, as well as the Cadiz and Weirton-Steubenville designated populated areas. Recall that HCA drinking water analysis only requires consideration of groundwater wells and not surface waters. This is an important distinction, as the Ambridge Reservoir is within the HCA zone but not part of Shell’s analysis — despite considerable risks outlined in our Falcon article on water body crossings.

Ecological Areas

Shell’s permits state that they consulted with the U.S. Fish and Wildlife Service (USFWS), Pennsylvania Game Commission (PGC), Pennsylvania Fish & Boat Commission (PFBC), and the Pennsylvania Department of Conservation and Natural Resources (DCNR) on their intended route in order to determine potential risks to protected species and ecologically sensitive areas.

DCNR responded that the pipeline had the potential to impact six sensitive plant species: Vase-vine Leather-Flower, Harbinger-of-spring, White Trout-Lily, Purple Rocket, Declined Trillium, and Snow Trillium. PFBC responded that the project may impact the Southern Redbelly Dace, a threatened temperate freshwater fish, within the Service Creek watershed. PGC responded that the pipeline had potential impact to habitats used by the Short-Eared Owl, Northern Harrier, and Silver-Haired Bat. Finally, the USFWS noted the presence of freshwater mussels in a number of water features crossed by the Falcon.

The presence of these species, as well as the proximity of protected lands illustrated on our map, factored into the Falcon’s HCA designations. A more detailed analysis of these issues is provided in the Falcon Public EIA Project article on Protected Habitats & Species of Concern.

The Falcon: Protected Habitats & Species of Concern

/by

Part of the Falcon Public EIA Project

Major pipeline projects are scrutinized by state and federal agencies for their potential impacts to threatened, endangered, and protected species. As part of the planning process, operators are required to consult with agencies to identify habitats known to support these species and are often asked to conduct detailed field surveys of specific areas. In this segment of the Falcon Pipeline EIA Project, we investigate how Shell corresponded with different agencies in complying with federal and state protected species guidelines.

Quick Falcon Facts

  • More than half (54%) of construction areas are currently forested or farmland
  • Botanical species Purple Rocket and Climbing Fern located in proximity to workspaces
  • 67 Northern Harrier observations documented during site studies
  • One active Bald Eagle nest and two inactive nests in proximity to workspaces
  • Northern Long-eared Bat roost trees discovered as close as 318 feet from workspaces
  • Clusters of protected freshwater mussels, coldwater fish, and hellbenders in the path of the Falcon

Map of Protected Habitats & Species of Concern

The following map will serve as our guide to exploring the Falcon’s proximity to protected habitats and species of concern. Expand the map full-screen to explore its contents in greater depth. Some layers only become visible at closer zoom levels. A number of additional layers are not shown by default, but can be turned on in the “layers” tab. Click the “details” tab in full-screen mode to read how the different layers were created.

View Map Fullscreen | How FracTracker Maps Work

Shell’s permit applications detail extensive correspondences over a number of years — as early as August 2015 — with the U.S. Fish and Wildlife Service (USFWS), Pennsylvania Game Commission (PGC), Pennsylvania Fish & Boat Commission (PFBC), Pennsylvania Department of Conservation and Natural Resources (DCNR), Ohio Department of Natural Resources (ODNR), and the West Virginia Division of Natural Resources (WVDNR), among other agencies. These interactions tell a story of locating and cataloging threatened flowers, birds of prey, aquatic species, and bats.

Land Cover Assessment

A number of terrestrial habitat types are present along the Falcon pipeline’s route that will be disrupted during its construction. These are easily determined using data maintained by the USGS that tracks land cover and land use trends often used for understanding geospatial biodiversity. Shell used this data in their ecological impacts analysis and we have used it as well for comparison.

Habitat documentations from Shell’s permit applications

More than half (54%) of land in the Falcon’s construction area is currently forested land (deciduous and evergreen). Shell’s permits describe these areas as “contained cool, forested stream valleys and seeps and rich slopes” similar to the image above, which was submitted as part of Shell’s permit applications. An additional 35% is currently farmland (pasture/hay/crops). The remaining land cover is generally made up of water and wetlands, as well as residential and commercial development.

These numbers reflect the fact that the Falcon will travel through predominantly rural areas. Note that this analysis does not account for disruptions that will result from the pipeline’s 111 temporary and 21 permanent access roads. Land Cover for areas along the pipeline can be seen on the FracTracker map by activating the data in the “layers” tab.

Botanical Studies

In their correspondences with state agencies, Shell was notified that a number of important species would likely be found in these habitats. For instance, Pennsylvania Department of Conservation and Natural Resources (DCNR) noted the following botanical species on their watch list would be present:

  • Vase-vine Leather-flower (endangered): documented in floodplain and slopes of Raccoon Creek
  • Harbinger-of-spring (rare): documented in forested floodplain of Raccoon Creek
  • White Trout-lily (rare): documented in forested floodplain of Raccoon Creek
  • Purple Rocket (endangered): documented in forested floodplain of Raccoon Creek
  • Declined Trillium (threatened): documented along wooded tributaries and slopes of Raccoon Creek
  • Snow Trillium (rare): documented in tributary ravines along Raccoon Creek

DCNR requested a survey the Falcon’s route through all of Beaver County and the portion of Allegheny County north of the western fork of Raredon Run. AECOM, Shell’s contractor for this work, surveyed a 300-foot wide buffer along the pipeline route to allow for “minor alignment shifts” as construction plans are refined.

A final survey report was submitted to DCNR in March 2017. In it, AECOM noted having found multiple populations of Harbinger-of-spring (seen below), Purple Rocket, as well as Climbing Fern (Lygodium palmatum), also the PA Watch List. FracTracker’s map locates the general location of botanical discoveries nearest to the pipeline route.

Documented Harbinger-of-spring

DCNR’s response to the survey stated that route changes and plans to bore under Raccoon Creek using HDDs eliminated risks to Harbinger-of-spring and Purple Rocket. Meanwhile, Climbing Fern was determined to be in close proximity, but not directly in the pipeline’s construction area. Although, documents note that a number of ferns were transplanted “to further the species’ success within the Commonwealth.” As a result of these determinations, DCNR granted clearance for construction in August 2017.

Short-eared Owls & Northern Harriers

Shell was also notified by the Pennsylvania Game Commission (PGC) that portions of the Falcon’s workspace would be located near six areas with known occurrences of Short-eared Owls (PA endangered species) and Northern Harriers (PA threatened species).

PGC requested a study of these areas to identify breeding and nesting locations, which AECOM executed from April-July 2016 within a 1,000-foot buffer of the pipeline’s workspace (limited to land cover areas consisting of meadows and pasture). One Short-eared Owl observation and 67 Northern Harrier observations were recorded during the study, but that some of these harriers appeared to be nesting just outside the study area. The study area is visible on the FracTracker map, as shown below.

AECOM’s Owl & Harrier study areas

In February 2017, Shell notified PGC that a number of reroutes had occurred that would shift the Falcon pipeline away from a subset of the observed Northern Harrier habitat. Although, there is no mention in the permit applications about identifying potential nest locations in the neighboring areas where AECOM’s biologists observed additional harriers. Nevertheless, PGC’s final determination in August 2017, approved the project, stipulating that, “based on the unusually high number of observations at these locations” work should not be done in these areas during harrier breeding season, April 15 through August 31.

Bald Eagles

The U.S. Fish & Wildlife Service (USFWS) notified Shell that a known Bald Eagle nest was located in Beaver County. Meanwhile, the Ohio Department of Natural Resources (ODNR) and West Virginia Division of Natural Resources (WVDNR) noted that two potential “alternate nests” were located where the Falcon crosses the Ohio River. National Bald Eagle Management Guidelines bar habitat disturbances that may interfere with the ability of eagles to breed, nest, roost, and forage.

AECOM surveyed these areas in March 2016 and March 2017. The first stage included an analysis of land cover data to determine other areas along the Falcon’s route that may be desirable eagle habitat. In addition to the sites noted above, AECOM determined that Fort Cherry Golf Course (discussed in gerater detail here) and Beaver Conservation District owned land (discussed in greater detail here) would serve as eagle habitat, although in later field surveys no additional nests were found.

The one active nest in close proximity to the Falcon, called the Montgomery Dam Nest, is located just west of the pipeline’s terminus at Shell’s ethane cracker facility. AECOM’s study determined that the foraging areas for a pair of eagles using the nest span the Ohio River and Raccoon Creek.

An additional nesting site was found near Tomlinson Run, along the Ohio River. During initial field observations it was noted that the nest was not in-use and is in an unmaintained condition. Nevertheless, its use by Bald Eagles as recently as 2015 means it is still considered an “alternate nest” and thus accorded protection from habitat modifications. A second alternate nest was found the west bank of the Ohio River. No previous history of the nest had been recorded by state agencies.

Bald Eagle Study Gaps?

Below are maps from Shell’s permit applications identifying the locations of the three nests. These can also be found on the FracTracker map.[/av_icon_box]

USFWS requested that Shell only implement setback buffers for the one active nest at Montgomery Dam. These include no tree clearing within 330 feet, no visible disturbances with 660 feet, and no excessive noise with 1,000 feet of an active nest. Furthermore, Shell must avoid all activities within 660ft of the nest from January 1st to July 31st that may disturb the eagles, including but not limited to “construction, excavation, use of heavy equipment, use of loud equipment or machinery, vegetation clearing, earth disturbance, planting, and landscaping.”

According to Shell’s permit applications, the reroute that occurred at the Ohio River crossing took the Falcon pipeline away from the two alternate nest sites of concern, and the crossing at the river will be done with HDD boring, thus no impacts will occur. Apparently USFWS agreed with this position. However, as we see in the above maps, the HDD staging area on the WV side of the river (where a great deal of noise will likely occur) is just barely outside the 1,000 foot buffer.

Important Bird Areas

USFWS determined that the Falcon pipeline was also in close proximity to many migratory bird species protected under the Migratory Bird Treaty Act and that “direct or indirect, unintentional take of migratory birds may result even if all reasonable measures to avoid avian mortality are utilized.” In particular, the USFWS brought attention to the Raccoon Creek Valley and State Park Important Bird Area (IBA), which is located just south and west of the Falcon pipeline’s two major branches, as seen below.

USFWS recommended a number of strategies, such as co-locating the Falcon pipeline along rights-of-way used by existing pipelines. We see this indeed became the case, as 11 of the Falcon’s 23 pipeline miles in Beaver County are found adjacent to or parallel to existing ROWs.

Additional restrictions were placed on the project in Ohio, where ODNR determined that the Falcon is within range of the Upland Sandpiper, a state endangered bird that nests in grasslands and pastures. Shell was instructed to avoid construction in these habitat types from April 15-July 31 if such areas were to be disturbed. As we can see on the FracTracker map’s analysis of land cover data, there are significant areas of grassland and pasture in Ohio along the pipeline route.

No Peregrine Falcon?

One absence we noted in AECOM’s birds of prey studies was any mention of Peregrine Falcons, listed as endangered and protected under the PA Game and Wildlife Code. Peregrine Falcons nest in cliffs and bridges along rivers in Allegheny and Beaver counties and are particularly prized by the PA DEP, as evidenced by a prominently displayed booth at their Harrisburg headquarters.

PA DEP Falcon Exhibit

One known nest is located under the East Rochester-Monaca Bridge just north of the Falcon pipeline’s terminus at Shell’s ethane cracker facility. While it is unlikely that activities such as tree clearing would affect falcon habitat, other aspects of the pipeline’s construction, such accidental drilling mud spills at HDD sites or ethane releases along Raccoon Creek, may indeed impact Falcon populations.

Federally Protected Bats

The USFWS notified Shell that the Falcon is located within the range of federally protected Indiana Bats and Northern Long-eared Bats in Pennsylvania and West Virginia and requested Shell conduct a bat “mist net” survey to identify breeding areas. Mist netting involves setting up nylon mesh nets at predetermined locations to capture and document bat populations.

AECOM’s bat survey was conducted from April-July 2016. While bats are known to live in caves and abandoned mines in winter, the study focused on summer habitats — mainly forests that support roost trees — given that tree clearing from building the pipeline would be the most likely impact. These forested areas constituted about 27 of the Falcon pipeline’s 97 miles in the two states. Mist net locations (MNLs) were established at 46 sites along the route, roughly 1/2 mile apart, as shown on the FracTracker map. A later reroute of the pipeline led to setting up 4 additional MNLs in June 2017.

A total of 274 bats from 6 different species were captured in the study, included 190 Big Brown Bats, 2 Silver-haired Bats, 62 Eastern Red Bats, 2 Hoary Bats, and 1 Little Brown Bat. 17 Northern Long-eared Bats were found at 13 of the MNL sites, but no Indiana Bats were captured. Radio transmitters were then attached to the Northern Long-eared Bats in order to follow them to roost trees. A total of 9 roost trees were located, with the nearest roost tree located 318 feet from the pipeline’s workspace.

A captured Northern Long-eared Bat

In January 2018, USFWS stated that, because the Falcon’s construction area is not within 150 feet of a known roost tree during breeding season or within a 1/4 mile of a known year-round hibernation site, that “incidental take that might result from tree removal is not prohibited.” However, USFWS also stated that “Due to the presence of several Northern Long-eared Bat roost trees within the vicinity of the project footprint (although outside of the 150-foot buffer), we recommend the following voluntary conservation measure: No tree removal between June 1 and July 31.”

Furthermore, the PGC noted in early correspondences that Silver-haired Bats may be in the region (a PA species of special concern). This was confirmed in AECOM’s mist net study. PGC did not require a further study for the species, but did request a more restrictive conservation of no tree clearing between April 1 and October 31.

Bat Study Gaps?

There are a number of possible gaps in AECOM’s study that need attention. First, the study notes the nearest roost tree is 318 feet from the Falcon’s workspace, but this does not fully represent the likely impact to bat populations. As is seen in the map below, taken from Shell’s permits, this tree is just one in a cluster of five trees all within 750 feet of the pipeline’s workspace.

A dense cluster of bat roosting trees

Furthermore, tree clearing in this area will be extensive considering its proximity to the Falcon’s juncture in Beaver County that also must accommodate a metering pad and access roads. This area is shown in the permit application map below and can be explored on the FracTracker map as well.

A second questionable aspect of the study is that, while the USFWS letter states the Falcon is not “within a 1/4 mile of a known year-round hibernation site,” this was not proven in the study as it did not identify nearby winter habitats. These omissions are noteworthy given the already significant stressors to bat populations in the region, as well as increasing pressure from oil and gas companies to relax standards for protecting endangered bat species.

A Note on Noise Control

As part of their ability to build the Falcon pipeline, USFWS mandated that Shell employ an “independent noise consultant” to measure ambient pre-construction noise levels at each HDD site and at designated Noise Sensitive Areas (NSA), which are generally determined by the presence of protected bird and bat species. Less is known about the details of this part of AECOM’s study plan for Shell. However, we have located noise monitoring sites on the FracTracker map for reference.

Freshwater Mussels

The USFWS and PGC identified very early in the Shell’s construction plans that the project would likely impact four endangered mussel species: the Northern Riffelshell, the Clubshell, the Rayed Bean, and the Snuffbox. AECOM conducted a survey in May 2016, at the request of Pennsylvania and Ohio agencies at 16 perennial streams along the route in those two states. These are shown on the FracTracker map. In PA, mussels were found to be present at both of the Falcon’s intersections with Raccoon Creek, as seen in a photo from Shell’s permit application below.

Documented freshwater mussels in Raccoon Creek

The results of the Ohio study are unknown at this time. However, we found it interesting that ODNR’s letter to Shell stated that unavoidable impacts could be resolved by allowing specialists to collect and relocate mussels to suitable and similar upstream habitats. Meanwhile, it appears that the USFWS and PFBC have also green lighted construction around the two known Raccoon Creek mussel habitats, as Shell’s applications argue these waters would not be impacted due to the fact that they would be crossing using HDD boring.

Coldwater Fish

The PA Fish & Boat Commission notified Shell that the Falcon may impact the Southern Redbelly Dace. This threatened species is especially vulnerable to physical and chemical (turbidity, temperature) changes to their environment. PAFB explicitly notes in their correspondences that “we are concerned about potential impacts to the fish, eggs and the hatching fry from any in-stream work.” Of note is that these sites of concern are located in HQ/CWF streams of the Service Creek watershed (discussed in greater detail here), as shown on the map below.

Headwater streams in the Service Creek watershed

Early correspondences with PFBC show the agency requesting that directional boring be used for these stream crossings or, if work necessitated direct impacts (such as open-cut crossings), that these activity be avoided during the spawning season. Shell responded to the request in stating that, with the exception of the Service Creek itself which will be crossed by HDD, the terrain surrounding its headwater streams was not suitable for boring, and would thus require open-cuts.

PFBC’s final determination on these matters is that they generally agreed, with the exception of the HDD site and one headwater stream (S-PA-151104-MRK-001), all other crossings must adhere to seasonal restrictions with no in-stream activity being conducted between May 1-July 31.

In Ohio, we see similar circumstances related to the River Darter, the Paddlefish, and the Channel Darter, all threatened species in the state. The ODNR recommended no in-stream work in the Ohio River from March 15-June 30 and no in-stream work in any of the state’s perennial streams from April 15-June 30.

Eastern Hellbenders

The Falcon is also within range of Eastern Hellbender habitat in Ohio, a state endangered species and a federal species of concern. In particular, ODNR noted that Yellow Creek, in Jefferson County, is known to host the species. Because of this, ODNR requested that if any in-stream work was to occur in Yellow Creek, a habitat suitability survey must be conducted to determine if Hellbenders were present. Yellow Creek’s tributaries are indeed crossed by the Falcon. Whether or not a study was conducted as a result of this is unknown due to our not having reviewed Shell’s Ohio permit applications. The below image, captured from our page on water crossings, shows these locations.

Falcon crossing Yellow Creek tributaries

Allowable Work Dates

To summarize, there are numerous implications for how Shell’s construction of the Falcon pipeline must accommodate endangered, threatened, and rare species in different states. In particular, Shell must avoid land and aquatic disturbances during different breeding and spawning seasons. Below is a breakdown of these black-out periods. Note that these only apply to locations where sensitive species were found in AECOM’s studies.

Land Disturbances

  • Northern Harriers, Short-eared Owls (PGC): No clearing between April 15 and August 31
  • Bald Eagles (USFWS): No work between January 1 and July 31
  • Upland Sandpiper (ODNR): No clearing between April 15 and July 31
  • Bats (USFWS): No clearing between April 1 and October 31

Aquatic Disturbances

  • Southern Redbelly Dace (PFBC): No in-stream work between May 1 and July 31
  • River Darter, Paddlefish, Channel Darter (ODNR): No Ohio River work between March 15 and June 30; no perennial stream work between April 15 and June 30

Falcon Pipeline: Cumulative Development & Compounded Risks

/by

Part of the Falcon Public EIA Project

In this final section of the Falcon Public EIA Project, we explore the Falcon pipeline’s entanglements with a region already impacted by a long history of energy development. Featured in this article are where the Falcon pipeline intersects underground mining facilities, strip mines, other hazardous pipelines, active oil and gas wells, as well as a very large compressor station. We utilize this information to locate spaces where cumulative development also has the potential for compounded risk.

Quick Falcon Facts

  • 20 miles of the Falcon run through under-mined areas; 5.6 miles through active mines
  • 18 miles of the Falcon run through surface-mined areas; also coal slurry waste site
  • Shares a right-of-way with Mariner West pipeline for 4 miles in Beaver County
  • 11 well pads, as well as a compressor station, are within the potential impact radius

Map of Falcon relative to mined areas and other energy-related development

The following map will serve as our guide in breaking down where the Falcon intersects areas that have experienced other forms of energy development. Expand the map full-screen to explore its contents in greater depth. Some layers only become visible as you zoom in. A number of additional features of the map are not shown by default, but can be turned on in the “layers” tab. These include information on geological features, water tables, soil erosion characteristics, as well as drinking reservoir boundaries. Click the “details” tab in full-screen mode to read how the different layers were created.


View Map Fullscreen | How FracTracker Maps Work

 

Mined Lands

The Falcon pipeline intersects a surprising number of active and inactive/abandoned mine lands. While the location of active mines is fairly easy to obtain from mine operators, finding data on abandoned mines is notoriously difficult. State agencies, such as the Pennsylvania Department of Environmental Protection (DEP), have digitized many legacy maps, but these resources are known to be incomplete and inaccurate in many locations.

AECOM’s engineers used data layers on active and abandoned mine lands maintained by state agencies in OH, WV, and PA. FracTracker obtained this data, as well, as shown on the interactive map. Shell states in their permits that AECOM’s engineers also went through a process of obtaining and digitizing paper maps in areas with questionable mine maps.

Shell states that their analysis shows that 16.8 miles of the Falcon pipeline travel through under-mined areas. Our analysis using the same dataset suggests the figure is closer to 20 miles. Of these 20 miles of pipeline:

  • 5.6 miles run through active coal mines and are located in Cadiz Township, OH (Harrison Mining Co. Nelms Mine); Ross Township, OH (Rosebud Mining Co. Deep Mine 10); and in Greene Township, PA (Rosebud Mining Co. Beaver Valley Mine). 
  • More than 18 miles run through areas that have been historically surface-mined (some overlapping under-mined areas).
  • Of those 18 miles, 1.5 miles run through an active surface mine located in Cadiz Township, OH, managed by Oxford Mining Company.

Beaver Valley Mine

The Beaver Valley Mine in Greene Township, PA, appeared to be of particular importance in Shell’s analysis. Of the three active mines, Shell maintained an active data layer with the mine’s underground cell map for reference in selecting routes, seen in the image below. Note how the current route changed since the map was originally digitized, indicating that a shift was made to accommodate areas around the mine. The FracTracker interactive map shows the mine based on PA DEP data, which is not as precise as the mine map AECOM obtained from Rosebud Mining.

Digitized map of Beaver Valley Mine

Rosebud Mining idled its Beaver Valley Mine in 2016 due to declining demand for coal. However, Rosebud appears to be expanding its workforce at other mines in the area due to changing economic and political circumstances. We don’t know exactly why this particular mine was highlighted in Shell’s analysis, or why the route shifted, as it is not directly addressed in Shell’s permit applications. Possibilities include needing to plan around areas that are known to be unfit for the pipeline, but also perhaps areas that may be mined in the future if the Beaver Valley Mine were to restart operations.

Coal Slurry Site, Imperial PA

As discussed in other segments of the Falcon Public EIA Project, Shell intends to execute 19 horizontal directional drilling (HDD) operations at different sites along the pipeline. A cluster of these are located in Allegheny and Washington counties, PA, with extensive historical surface mining operations. A 2003 DEP report commented on this region, stating:

All of the coal has been underground mined. Most of the coal ribs and stumps (remnants from the abandoned underground mine) have been surface mined… The extensive deep mining, which took place from the 1920’s through the 1950’s, has had a severe effect on groundwater and surface water in this watershed.

Shell’s applications note that AECOM did geotechnical survey work in this and other surface-mined areas co-located with proposed HDD operations, concluding that the ”majority of rock encountered was shale, sandstone, limestone, and claystone.” However, at one proposed HDD (called “HOU-06”) the Falcon will cross a coal waste site identified in the permits as “Imperial Land Coal Slurry” along with a large Palustrine Emergent (PEM) wetland along Potato Garden Run, seen below.

A Falcon HDD crossing under a wetland and coal slurry site

Foreign Pipelines

In addition to its entanglements with legacy coal mining, the Falcon will be built in a region heavily traveled by oil and gas pipelines. More than 260 “foreign pipelines” carrying oil, natural gas, and natural gas liquids, were identified by AECOM engineers when selecting the Falcon’s right-of-way (note that not all of these are directly crossed by the Falcon).

Owners of these pipelines run the gamut, including companies such as Williams, MarkWest, Columbia, Kinder Morgan, Energy Transfer Partners, Momentum, Peoples Gas, Chesapeake, and Range Resources. Their purposes are also varied. Some are gathering lines that move oil and gas from well pads, others are midstream lines connecting things like compressor stations to processing plants, others still are distribution lines that eventually bring gas to homes and businesses. FracTracker took note of these numbers and their significance, but did not have the capacity to document all of them for our interactive map.

Shared Rights-of-Way

However, we did include one pipeline, the Mariner West, because of its importance in the Falcon’s construction plans. Mariner West was built in 2011-2013 as part of an expanding network of pipelines initially owned by Sunoco Pipeline but now operated by Energy Transfer Partners. The 10-inch pipeline transports 50,000 barrels of ethane per day from the Separator plant in Houston, PA, to processing facilities in Canada. Another spur in this network is the controversial Mariner East 2. 

Mariner West is pertinent to the Falcon because the two pipelines will share the same right-of-way through a 4-mile stretch of Beaver County, PA, as shown below.

The Falcon and Mariner West sharing a right-of-way

Reuse of existing rights-of-way is generally considered advantageous by pipeline operators and regulatory agencies. The logistics of sharing pipelines can be complicated, however. As noted in Shell’s permit applications:   

Construction coordination will be essential on the project due to the numerous parties involved and the close proximity to other utilities. Accurate line location was completed; however, verification will also be key, along with obtaining proper crossing design techniques from the foreign utilities. A meeting with all of pipeline companies will be held to make sure that all of the restrictions are understood prior to starting construction, and that they are documented on the construction alignment sheets/bid documents for the contractor(s). This will save a potential delay in the project. It will also make working around the existing pipelines safe.

Shell’s attention to coordinating with other utility companies is no doubt important, as is their recognition of working near existing pipelines as a safety issue. There are elevated risks with co-located pipelines when they come into operation. This was seen in a major pipeline accident in Salem Township, PA, in 2016. One natural gas line exploded, destroying nearby homes, and damaged three adjacent pipelines that took more than a year to come back online. These findings raise the question of whether or not Class Location and High Consequence Area assessments for the Falcon should factor for the exponential risks of sharing a right-of-way with Mariner West.

Oil & Gas Extraction

The remaining features included on our map relate to oil and gas extraction activities. The Falcon will carry ethane from the three cryogenic separator plants at the pipeline’s source points. But the wet, fracked gas that supplies those plants also comes from someplace, and these are the many thousands of unconventional gas wells spread across the Marcellus and Utica shale.

We found 11 unconventional oil and gas pads, hosting a combined 48 well heads, within the Falcon’s 940-foot PIR. We also found a large compressor station operated by Range Resources, located in Robinson Township, PA. This is shown below, along with a nearby gas pad.

A well pad and compressor station in Falcon’s PIR

We noted these well pads and the compressor station because Class Location and HCA risk analysis may account for proximity to occupied businesses and homes, but does not always consider a pipeline’s proximity to other high-risk industrial sites. Nevertheless, serious incidents have occurred at well pads and processing facilities that could implicate nearby hazardous liquid pipelines. By the same measure, an accident with the Falcon could implicate one of these facilities, given they are all within the Falcon’s blast zone.

Energy development is happening on your state lands, Pennsylvania

/by

Decisions to drill or mine on public lands, however, are often extremely complicated.

By Allison M. Rohrs, Saint Francis University, Institute for Energy

The Commonwealth of Pennsylvania has historically been, and continues to be, home to an abundant array of energy resources like oil, gas, coal, timber, and windy ridgetops. Expectedly, these natural resources are found both on publicly and privately held land.

In Pennsylvania, the bulk of public lands are managed by two separate state agencies: The Department of Conservation and Natural Resources (DCNR), which manages the state’s forest and park system, and the Pennsylvania Game Commission (PGC), which manages the state’s game lands. Both of these state agencies manage oil, gas, and coal extraction as well as timbering on state property. Interestingly, neither of the agencies have utility-scale renewable energy generation on their land.

Some of Pennsylvania’s best wind resources can be found on the mountain ridges in the Commonwealth’s state forests and game lands, however, all proposals to build utility-scale wind farms have been denied by state agencies.

(Note: there are other state and federal agencies managing lands in PA, however, we focused our research on these two agencies specifically.)

Surprised to see that state lands have been greatly developed for different fossil industries but denied for wind energy, The Institute for Energy set out on a yearlong endeavor to collect as much information as we could about energy development on PA public lands. Using formal PA Right to Know requests, we worked with both DCNR and PGC to examine development procedures and management practices. We reviewed hundreds of available state agency reports, scientific documents, and Pennsylvania energy laws and regulations. We also worked with FracTracker Alliance to develop interactive maps that depict where energy development has occurred on state lands.

After a comprehensive review, we realized, like so much in life, the details are much more complicated than a simple yes or no decision to develop an energy project on state lands. Below is a brief summary of our findings, organized by energy extraction method:

Land/Mineral Ownership in Pennsylvania

One of the most significant issues to understand when discussing energy resources on state lands is the complexity of land ownership in Pennsylvania. In many instances, the development of an energy resource on publicly owned land is not a decision, but instead an obligation. In Pennsylvania, property rights are often severed between surface and subsurface ownership. In many cases, surface owners do not own the mineral rights beneath them, and, by PA law, are obligated to allow reasonable extraction of such resource, whether it be coal, oil, or gas. In Pennsylvania, approximately 85% of state park mineral rights are owned by someone other than the Commonwealth (severed rights).

Fee Simple - Mineral rights on state lands

Legal Authority to Lease

It is critical to note that DCNR and PGC are two entirely separate agencies with different missions, legal structures, and funding sources. This plays a significant role in decisions to allow oil, gas, and coal development on their properties. Both agencies have explicit legal authority under their individual statutes that allow them to lease the lands for mineral extraction. This becomes more of an issue when we discuss wind development, where legal authority is less clear, particularly for DCNR.

Oil and Gas Extraction

Oil and gas wells have been spudded on state parks, state forests, and state game lands. The decision to do so is multifaceted and ultimately decided by three major factors:

  1. Mineral ownership of the land,
  2. Legal authority to lease the land, and
  3. Potential impacts to the individual agency.

There is currently a moratorium on new surface leases of DCNR Lands. Moratoriums of such nature have been enacted and removed by different governors since 2010. Although there are no new lease agreements, extraction and production is still occurring on DCNR land from previously executed lease agreements and where the state does not own the mineral rights.

The Game Commission is still actively signing surface and non-surface use agreements for oil and gas extraction when they determine the action is beneficial to achieving their overall mission.

Revenues from the oil and gas industry play a significant role in the decision to drill or not. Both agencies have experienced increasing costs and decreasing revenues, overall, and have used oil and gas development as a way to bridge the gap.

Funds raised from DCNR’s oil and gas activities go back to the agency’s conservation efforts, although from 2009 to 2017, the State Legislature had directed much of this income to the state’s general fund to offset major budget deficits. Just this year, the PA Supreme Court ruled against this process and has restored the funds back to DCNR for conservations purposes.

All revenues generated from oil and gas development on state game lands stays within the Game Commission’s authority.

Along with positive economic benefits, there remains potential health and environmental risks unique to development on these public lands. Some studies indicate that users of these public lands could have potential exposure to pollution both in the air and in the water from active oil and gas infrastructure. The ease of public access to abandoned and active oil and gas infrastructure is a potential risk, as well. On the environmental side, many have argued that habitat fragmentation from oil and gas development is contradictory to the missions of the agencies. Both agencies have independent water monitoring groups specific to oil and gas activities as well as state regulated DEP monitoring. The potential negative effects on ground and surface water quality is an issue, however, mainly due the vast size of public lands and limited dwellings on these properties.

Use the map below to explore the PA state parks, forests, and game lands that have active oil and gas infrastructure.

Coal Mining

Thousands of acres of state forests and game lands have been mined for coal. Like oil and gas, this mineral is subject to similar fee simple ownership issues and is governed by the same laws that allow oil and gas extraction. DCNR, has not signed any virgin coal mining leases since the 1990s, but instead focuses on reclamation projects. There are coal mining operations, however, on forest land where DCNR does not own the mineral rights. The Game Commission still enters into surface and non-surface use agreements for mining.

In many circumstances, mining activity and abandoned mines were inherited by the state agencies and left to them to reclaim. Environmental and health impacts of mining specific to state land are generally attributed more to legacy mining and not to new mining operations.

Acid mine drainage and land subsidence has destroyed rivers and riparian habitats on these lands purposed for conservation.

The ease of public access and limited surveillance of public lands also makes abandoned mines and pits a dangerous health risk. Although threats to humans and water quality exist, abandoned mines have been noted for actually creating new bat habitat for endangered and threatened bat species.

Originally, we sought to quantify the total acreage of public lands affected by coal mining and abandoned mines; however, the dataset required to do so is not yet complete.

The Pennsylvania Department of Environmental Protection is currently in the process of digitizing over 84,000 hand drawn maps of mined coal seams in PA, an expected 15-year project.

Today, they have digitized approximately 30,000. The static map below demonstrates the areas with confirmed coal mining co-located on state lands:
Public lands and coal mining map - PA

Renewables

The discussion about renewable energy development in PA is almost as complex as the fossil industries. There are no utility-scale renewables on state owned land. Both DCNR and the Game Commission have been approached by developers to lease state land for wind development, however all proposals have been denied.

Even when DCNR owns the surface rights, they still cite the lack of legal authority to lease the land for wind, as their statute does not explicitly state “wind turbines” as a lawful lease option.

The Game Commission does have the legal authority to lease its land for wind development, but has denied 19 out of 19 requests by developers to do so, citing many environmental and surface disturbances as the primary reason.

Infographic regarding state land potential for wind energy

The development of wind projects in PA has slowed in the past five years, with only one new commercial wind farm being built. This is due to a variety of reasons, including the fact that many of windiest locations on private lands have been developed.

We estimate that 35% of the state’s best wind resource is undevelopable simply because it is on public land.

Like all energy development, wind energy has potential environmental and health impacts, too. Wind could cause habitat fragmentation issues on land purposed for conservation. The wind energy industry also has realized negative effects on bird and bat species, most notably, the endangered Indiana bat. Health impacts unique to public lands and wind development include an increased risk of injury to hunters and recreators related to potential mechanical failure or ice throw off the blades. Unlike fossil energies, however, wind energy has potential to offset air emissions.

We estimate that wind development on PA public lands could offset and estimated 14,480,000 tons of CO2 annually if fully developed.

Commercial wind turbines are currently being installed at hub heights of 80-100 meters where the annual average wind resource is 6.5 m/s or greater. The following map demonstrates areas of Pennsylvania where the wind speeds are 6.5 m/s or greater at 100 meters, including areas overlapping state lands, where no utility scale development has occurred.

Additional Renewables

Biomass is organic material, such as wood, that is considered renewable because of its ability to be replenished. The harvesting of such wood (timber) occurs on both DCNR and PGC lands and provides funding for these agencies.

Small-scale wind, solar, hydro, geothermal, and biomass projects do exist on PA public lands for onsite consumption, however no renewables exist on a commercial or utility scale.

Both the fossil and renewable energy industries are forecasted to grow in Pennsylvania in the years to come. The complex decisions and obligations to develop energy resources on PA public lands should include thoughtful management and fair use of these public lands for all energy resources.

Giving Voice to the Sandhill Cranes: Place-based Arguments against Keystone XL

/by

By Wrexie Bardaglio, guest commentator

When we hear his call, we hear no mere bird. We hear the trumpet in the orchestra of evolution. He is the symbol of our untamable past, of that incredible sweep of millennia which underlies and conditions the daily affairs of birds and men…” ~ Aldo Leopold, on the Sandhill Crane, in “Marshland Elegy”

Dilbit – or diluted bitumen – is refined from the naturally-occurring tar sands deposits in Alberta, Canada. In March 2017, I applied to the Nebraska Public Service Commission for standing as an intervenor in the Commission’s consideration of TransCanada’s request for a permit to construct a pipeline transporting dilbit – a project referred to as the Keystone XL pipeline. Below are my reflections on the battle against the permitting process, and how FracTracker’s maps ensured the Sandhill Crane’s voice made it into public record.

A Pipeline’s History

The Keystone 1 pipeline carries the dilbit from Alberta, to Steele City, Nebraska, and ultimately to Port Arthur, Texas and export refineries along the Gulf Coast. The state of Montana had already approved the Keystone XL project, as had the state of South Dakota. The decision of the South Dakota Public Utilities Commission was appealed, however, and has now worked its way to the South Dakota Supreme Court, where it is pending.

Resistance to TransCanada’s oil and gas infrastructure projects is not new. Beginning in 2010, some Nebraska farmers and ranchers joined forces with tribal nations in the Dakotas, who were also fighting TransCanada’s lack of proper tribal consultation regarding access through traditional treaty territory. The indigenous nations held certain retained rights as agreed in the 1868 Fort Laramie Treaty between the United States government and the nine tribes of the Great Sioux Nation. The tribes were also protesting TransCanada’s flaunting of the National Historic Preservation Act’s protections of Native American sacred sites and burial grounds. Further, although TransCanada was largely successful in securing the easements needed in Nebraska to construct the pipeline, there were local holdouts refusing to negotiate with the company. TransCanada’s subsequent attempts to exercise eminent domain resulted in a number of lawsuits.

In January of 2015, then-President Barack Obama denied the international permit TransCanada needed. While that denial was celebrated by many, everyone also understood that a new president could well restore the international permit. Indeed, as one of his first actions in January 2017, the new Republican president signed an executive order granting the permit, and the struggle in Nebraska was reignited.

“What Waters Run Through My Veins…”

While I am a long-time resident of New York, I grew up in the Platte River Valley of South Central Nebraska, in a town where my family had and continues to have roots – even before Nebraska became a state. There was never a question in my mind that in this particular permitting process I would request status as an intervenor; for me, the matter of the Keystone XL Pipeline went far beyond the legal and political and energy policy questions that were raised and were about to be considered. It was about who I am, how I was raised, what I was taught, what waters run through my veins as surely as blood, and who my own spirit animals are, the Sandhill Cranes.

Bardaglio (age 3) and her father, along the banks of the Platte River

When we were growing up, our father told us over and over and over about why Nebraska was so green. The Ogallala Aquifer, he said, was deep and vast, and while eight states partially sat atop this ancient natural cistern, nearly all of Nebraska floated on this body. Nebraska was green, its fields stretching to the horizon, because, as our father explained, the snow runoff from the Rockies that flowed into our state and was used eleven times over was cleansed in water-bearing sand and gravel on its way to the Missouri on our eastern boundary, thence to the Mississippi, and finally to the Gulf.

I grew up understanding that the Ogallala Aquifer was a unique treasure, the largest freshwater aquifer in the world, the lifeblood for Nebraska’s agriculture and U.S. agriculture generally, and worthy of protection. I thought about the peril to the aquifer because of TransCanada’s plans, should there be a spill, and the additional threats an accident would potentially pose to Nebraska’s rivers, waterways and private wells.

2000px-ogallala_saturated_thickness_1997-sattk97-v2-svg

The Ogallala Aquifer

Knowing that climate change is real, terrifying, and accelerating, I recognized that a warming world would increasingly depend on this aquifer in the nation’s midsection for life itself.

Migration of the Sandhill Cranes

As I thought about how I would fight the KXL, another narrative took shape rising out of my concern for the aquifer. Growing up in the South Central Platte River Valley, I – and I daresay most everyone who lives there – have been captivated by the annual migration of the Sandhill Cranes, plying the skies known as the Central Flyway. As sure as early spring comes, so do the birds. It may still be bitterly cold, but these birds know that it is time to fly. And so they do – the forward scouts appearing in winter grey skies, soon followed by some 500,000 – 600,000 thousand of them, darkening the skies, their cries deafening and their gorgeous archaeopteryx silhouettes coming in wave after wave like flying Roman Legions.

branch-bird-sky-sunrise-sunset-morning-dawn-flock-dusk-birds-cranes-water-bird-bird-migration-migratory-birds-atmospheric-phenomenon-animal-migration-crane-like-bird-529634

To this day, no matter where I am, the first thing in my sinews and bones when winter begins to give way is the certainty that the birds are coming, I feel them; they are back. They are roosting on the sandbars in the braided river that is the Platte and gleaning in the stubbled fields abutting it… they are home.

According to The Nature Conservancy:

Scientists estimate that at least one-third of the entire North American population of Sandhill Cranes breed in the boreal forest of Canada and Alaska…

Scientists estimate that approximately 80 percent of all Sandhill Cranes in North America use a 75-mile stretch of Nebraska’s Platte River during spring migration. From March to April, more than 500,000 birds spend time in the area preparing for the long journey north to their breeding grounds in Canada and Alaska. During migration, the birds may fly as much as 400 miles in one day.

Sandhill Cranes rely on open freshwater wetlands for most of their lifecycle. Degradation of these kinds of wetland habitats is among the most pressing threats to the survival of Sandhill Cranes. (Emphasis added)

Giving Sandhill Cranes a Voice

But how could I make the point about the threat TransCanada posed to the migratory habitat of the Sandhill Cranes (and endangered Whooping Cranes, pelicans, and hummingbirds among the other thermal riders who also migrate with them)? Books, scientific papers, lectures – all the words in the world – cannot describe this ancient rite, this mysterious primal navigation of the unique pathway focusing on this slim stretch of river, when viewed from a global perspective a fragile skein in a fragile web in a biosphere in peril.

In my head I called it a river of birds in the grassland of sky. And I am so grateful to my friend, Karen Edelstein at FracTracker Alliance, for her willingness to help map and illustrate the magnificence of the migration flyway in the context of the three proposed options for the KXL pipeline.

flyway_map

Karen prepared two maps for me, but my favorite is the one above.

It shows an ancient, near-primordial, near-mystical event. Guided by rudders and instinct we can barely comprehend, in concert with earth’s intrinsic and exquisitely-designed balance, and as certain as a sunrise, a sunset or a moon rise, these oldest of crane species find their ways through the heavens. They hew to certainties that eclipse the greed of multinational corporations like TransCanada, who barely even pay lip service to the integrity of anything over which they can’t exert dominion. To say they don’t respect the inherent rights of species other than our own, or to ecological communities that don’t directly include us, is an understatement, and a damning comment on their values.

I was prepared for pushback on these maps from TransCanada. And in truth, the company was successful in an in limine motion to have certain exhibits and parts of my testimony stricken from the official record of the proceedings.

But not the maps.

In fact, too many other intervenors to count, as well as several of the lawyers involved in the proceedings commented to me on the beauty and accuracy of the maps. And not only are they now a part of the permanent record of the Nebraska Public Service Commission, should there be an appeal (which all of us expect), on both sides of the issue, there is a very good possibility they will be incorporated into the formal testimonies by the lawyers as the matter moves through the appeals process.

Taking Action, Speaking Out

Ordinary citizens must figure out how to confront the near-impenetrable stranglehold of multi-national corporations whose wealth is predicated on the continuance of fossil fuels as the primary sources of energy. We have had to become more educated, more activist, and more determined to fight the destruction that is now assured if we fail to slow down the impacts of climate change and shift the aggregate will of nations towards renewable energy.

Many activists do not realize that they can formally intervene at the state level in pipeline and infrastructure permitting processes. In doing so, the voice of the educated citizen is amplified and becomes a threat to these corporations whose business models didn’t account for systematic and informed resistance in public agencies’ heretofore pro forma proceedings. The publicly-available documents and filings from corporations can be important tools for “speaking truth to power” when paired with the creative tools born of necessity by the environmental movement.

Technology is value-neutral, but as I learned – as did many others in the Keystone XL Pipeline fight – in skilled hands it becomes a weapon in the struggle for the greater good.

I will be forever grateful for FracTracker, and will be interested to see how others use this tool in the fights that are sure to come.

EXCELSIOR!

Nationally treasured federal lands face threats by oil, gas, and other extractive uses

/by

Should public, federal lands be opened up even further for extracting minerals, oil, and gas for private ventures? FracTracker’s Karen Edelstein discusses the past, present, and potential future of many of America’s cherished natural resources and wonders.

The United States is blessed with some of the most diverse natural landscapes in the world. Through foresight of great leaders over the decades, starting in 1906 — Theodore Roosevelt, Franklin Roosevelt, Benjamin Harrison, and Jimmy Carter – to name just a few — well over a half billion acres of wilderness have been set aside as national parks, refuges, monuments, and roadless areas. Some of the most famous of these protected areas include the Grand Canyon, Acadia, and Grand Tetons National Parks. In all, the federal government owns 28% of the 2.27 billion acres of land that the United States comprises. These federal lands are administered by the Bureau of Land Management (BLM): 248.3 million acres, the US Forest Service: 192.9 million acres, US Fish and Wildlife Service: 89.1 million acres, and National Park Service: 78.9 million acres. In addition, the US Department of Defense administers 11.4 million acres.

Why are federal lands at risk?

While most people assume that federal wild lands are forever protected from development and commercial exploitation, quite the opposite is true. For most of the past century, federal lands have hunted, fished, logged and grazed by private individuals and enterprises. In addition, and in the cross-hairs of discussion here, is the practice of leasing lands to industrial interests for the purpose of extracting minerals, oil, and gas from these public lands.

Provisions for land conservation and restrictions on oil and gas extraction, in particular, became more stringent since the inception of the Environmental Protection Agency (EPA) in 1970. However, environmentalists have watched in horror as the current administration in Washington has gutted the EPA, and installed climate change-deniers and corporate executives in high levels of office throughout a range of federal agencies. Notable is the appointment of Ryan Zinke as US Secretary of the Interior. Zinke, a former businessman, has a long record of opposing environmental viewpoints around extraction of oil, coal, and gas and cutting regulations. The League of Conservation Voters gives his voting record a lifetime score of 4 percent on environmental issues. As recently as this week, Joel Clement–one of Zinke’s senior advisors–resigned his post, citing, Zinke’s poor leadership, wasting of tax-payer dollars, and denial of climate change science.

Early in his tenure as Secretary of the Interior, Zinke initiated a review of 27 national monuments, a move that environmentalists feared could lead to the unraveling of protections on millions of acres of federal land, and also relaxed regulations on oil and gas exploration in those areas. Public comment on the plans to review these national monuments was intense; when the public comment period closed on July 10, 2017, the Interior Department had received over 2.4 million comments, the vast majority of which supported keeping the existing boundaries and restrictions as they are.

Who should be allowed to use these resources?

Ranchers, loggers, and recreational hunters and anglers felt that the 1906 Antiquities Act had been over-interpreted, and therefore advocated for Zinke’s proposal. (The Act was the first U.S. law to provide protection for any general kind of cultural or natural resource.)

However, environmental advocates such as the National Parks Conservation Association (NPCA), the Natural Resources Defense Council (NRDC), and others were adamantly opposed to opening up federal lands resources for extraction, citing the need for environmental protection, public access, and, importantly, concerns that the lands would be more easily transferred to state, local, or private interests. Environmentalists also argue that the revenue generated by tourism at these pristine sites would far exceed that generated by extractive resource activities. Attorneys and staff from NPCA and NRDC argued legislation in effect since the 1970s requires role for Congress in changing the boundaries of existing monuments. The President or his cabinet do not have that sole authority.

The Wilderness Society estimates that already, 90% of the land in the US West, owned by the Bureau of Land Management, is open for oil and gas leasing, while only 10% is set aside for other uses (Figure 2). According to information from Sourcewatch, in 2013, these lands included 12 National Monuments, Parks, Recreation Areas, and Preserves that had active drilling, and another 31 that might see possible drilling in the future.

What Zinke has Proposed

True to expectation, in August of 2017, Zinke issued a recommendation to shrink the boundaries of several national monuments to allow coal mining and other “traditional uses” — which appear to include large-scale timbering, as well as potentially oil and gas drilling. Sites include Bears Ears and Grand Staircase-Escalante in Utah (encompassing more than 3.2 million acres in lands considered sacred to Dine/Navajo people), Cascade-Siskiyou in Oregon, and Gold Butte in Nevada. According to Zinke’s report, Grand Staircase-Escalante contains “an estimated several billion tons of coal and large oil deposits”. Zinke lifted Obama-era restrictions on coal leasing on federal lands this past March, 2017. However, just last week, a federal judge ruled that the current Administration’s efforts to suspend methane emission restrictions from pipelines crossing public lands were illegal. These are merely a few of the Obama-era environmental protections that Zinke is attempting to gut.

Zinke has proposed decreasing the size of Bears Ears National Monument from the current 1.35 million acres to a mere 160,000, a reduction of 88%. The Bears Ears Inter-Tribal Coalition, made up of thirty Native American tribes, condemned the recommendation as a “slap in the face to the members of our Tribes and an affront to Indian people all across the country.” The Navajo Nation intends to sue the President’s administration if this reduction at Bears Ears is enacted.

Bears Ears National Monument, designated by President Barack Obama, contains tens of thousands of cultural artifacts, and is facing not only a threat of boundary shrinkage, but also a relaxing use restrictions within the Monument area. The current President has referred to Obama’s designation of the monument as “an egregious abuse of power.” Grand Staircase-Escalante was designated by President Bill Clinton, and the Cascade-Siskiyou National Monument was designated by Clinton and expanded by President Obama.

The recommendation details were not made public in August, however, and only came to light in September through a leaked memo, published in The Washington Post. In the memo, Secretary Zinke noted that the existing boundaries were “arbitrary or likely politically motivated or boundaries could not be supported by science or reasons of resource management.” The memo goes on to say that “[i]t appears that certain monuments were designated to prevent economic activity such as grazing, mining and timber production rather than to protect specific objects.” In addition, Zinke is advocating for the modification for commercial fishing uses of two marine national monuments: the Pacific Remote Islands, and Rose Atoll.

Lacking Specificity

According to the Washingon Post, Zinke:

… plans to leave six designations in place: Colorado’s Canyons of the Ancients; Idaho’s Craters of the Moon; Washington’s Hanford Reach; Arizona’s Grand Canyon-Parashant; Montana’s Upper Missouri River Breaks; and California’s Sand to Snow.

Perplexingly, the report is silent on 11 of the 27 monuments named in the initial proposal. One of which is the Papahanaumokuakea Marine National Monument — over 725,000 square miles of ocean — in the northwestern Hawaiian Islands.

The report also requests tribal co-management of “cultural resources”  at Bears Ears, Rio Grande del Norte, and Organ Mountain-Desert Peaks. While one could imagine that greater involvement of indigenous people in the federal government’s management of the sacred landscapes to be a potentially positive improvement, the report is silent on the details. More information on tribal co-management and other options can be gleaned from a series of position papers written by the Property and Environment Research Center.

Of other note: Zinke is also suggesting the establishment of three new national monuments, including the 130,000-acre Badger-Two Medicine area in Montana, a sacred site of the Blackfeet Nation. Badger-Two Medicine was the site of a more than 30-year battle to retire 32,000 acres of oil and gas leases. The tribe prevailed, and the leases were canceled in November, 2016.

With potential lawsuits pending about boundary changes, galvanized push-back from environmental and tribal interests on resource management definitions for the targeted monuments, and general unpredictability on policy details and staffing in Washington, the trajectory of how this story will play out remains uncertain. FracTracker will continue to monitor for updates, and provide additional links in this story as they unfold.

Protect Greater Chaco: Drone surveillance of regional fracking sites in NM

/by

The River Healers have droned multiple fracking sites in the Greater Chaco Area (New Mexico) impacted by explosions, fires, spills, and methane. See what they are finding. Hear their story.

 

By Tom Burkett – River Healer Spokesperson, New Mexico Watchdog

The Greater Chaco region is known to the Diné (Navajo) as Dinétah, the land of their ancestors. It contains countless sacred sites that date to the Anasazi and is home of the Bisti Badlands and Chaco Culture National Historical Park, a World Heritage Site. Currently WPX Energy has rights to lease about 100,000 acres of federal, state, and Navajo allottee lands in the oil rich San Juan Basin, which includes Greater Chaco.1 WPX Energy along with other fracking companies plan to continue establishing crude oil fracking wells on these sacred lands, although the Greater Chaco community has spoken out against fracking and continue to call for more safety and oversight from New Mexico state regulatory bodies such as the EMNRD Oil Conservation Division.

The River Healers pulled EMNRD records that show over 8,300 spills in New Mexico had been reported by the the fracking industry to EMNRD between 2011-2016 (map below). This is thousands more than reported by the Environmental Protection Agency. The records also showed how quickly reports of spills, fires, and explosions were processed by the EMNRD as ‘non-emergency’ and accepted industry reports that no groundwater had been contaminated.

Daniel Tso, Member of the Navajo Nation and Elder of the Counselor Chapter, led us to fracking sites in Greater Chaco that had reported spills and fires. Daniel Tso is one of many Navajo Nation members working on the frontlines to protect Greater Chaco, their ancestral land, and their pastoral ways of life from the expanding fracking industry. Traveling in white trucks and cars we blended in with the oil and gas trucks that dot indigenous community roads and group around fracking pads on squares federally owned land. Years of watchdogging the fracking destruction on their sacred land was communicated through Tso’s eyes looking over the landscape for new fracking disruption and a calm voice,

… the hurt on the sacred landscapes; the beauty of the land is destroyed, this affects our people’s mental, spiritual, and emotional health.

At each site our eyes were scanning the fracking sites and terrain for drone flight patterns while the native elders were slowly scanning the ground for pottery shards and signs of their ancestors. Arroyos sweep around the fracking pads and display how quickly the area can flash flood from rain that gathers on the striated volcanic ash hills of the badlands.

Fracking Regulation in NM

The EMNRD Oil Conservation Division has only 12 inspectors that are in charge of overseeing over 50,000 wells scattered throughout New Mexico.2 Skepticism around EMNRD’s ability to regulate not only comes from a short staff being stretched across 121,598 square miles of New Mexico’s terrain, but thousands of active fracking sites continue to report spills, fires, and explosions every year.3 Even more problematic is that Ken McQueen, Cabinet Secretary of EMNRD formerly served as Vice President of WPX Energy.4 Ken McQueen managed WPX Energy’s assets in the Four Corners area of New Mexico, Colorado, and in addition, part of Wyoming. New Mexico Governor, Susana Martinez’s appointment of McQueen severely compromises the state’s ability to impartially oversee WPX Energy and regulate the fracking industry. Governor Martinez has been called to clean up the EMNRD, and rid the regulatory body of cabinet members more interested in protecting the assets of WPX than the health and rights of New Mexicans. Tso remarks,

The sacrifices of indigenous communities continue for a society that thinks gasoline comes from a gas station. That thinks oil is a commodity that is unending resource. This is unfortunate, and ultimately compromises our physical health. Yet this doesn’t matter to the industry. They want every last drop of crude oil even if it is cost prohibitive.

The River Healers maintain that Governor Martinez is complicit in the exploitation of human water rights as long as the EMNRD remains a compromised and unreliable regulatory body.

New Mexico governmental assimilation with the oil and gas industry is presented to the Greater Chaco indigenous communities in the form of 90,000-lb gross weight oilfield trucks. Western Refining started rolling out trucks with larger-than-life prints of state and county law enforcements officers and military personnel at the same time water protectors at Standing Rock were being arrested and assaulted by the Morton County Sheriff’s Department in North Dakota.5 The indigenous-led movement to stop the Dakota Access Pipeline from desecrating sacred land and threatening rights to clean water has drawn greater resistance to oil and gas projects around the country.

Indigenous solidarity is felt in Greater Chaco, but Western Refining’s blatant propaganda campaign demonstrates how oil and gas corporations continue to threaten and silence the communities they extract oil from by displaying the paid power of state and federal law enforcement. The River Healers view this as a direct form of intimidation that aims to further a corporate ideology and remind native communities of the violence they experienced at the hand of the United States Federal Government in the past. The Western Refining campaign is a direct form of corporate-sponsored terrorism and should be grounds to ban their ability to use images of law enforcement officers to further their interests. Furthermore, the state should discontinue paying for officers to patrol facking roads and pads and instead use state funds to make state regulatory bodies work for the communities most impacted by the oil and gas industries.

What we are finding

Drone surveillance of fracking sites in Greater Chaco show how quickly the fracking industry has exploited a state government tied to the interests of a booming and unchecked resource extraction industry. In Greater Chaco this element of time is more deeply understood through the lens of the indigenous community.

Ultimately, the health of the fauna and flora are devastated. The adaptation of the delicate ecosystem is forever destroyed. Their recovery and healing will take years and years.

The Anasazi Kivas in Chaco Canyon took over 300 years to construct, while drill rigs such as Cyclone 32 take less than 10 days to drill 6,500 ft wells in the canyon plateau. We hiked 12 miles of the sacred Chaco Wash, pulled water samples, and saw the red palm of the Supernova Petrograph clinging to the understory of the canyon wall, clearly taking notice of what is happening above.

We deeply thank members of the Navajo Nation for inviting us into their lives, and our hearts stand with them in solidarity. Protect Greater Chaco! Dooda Fracking!

This particular site caught fire on June 11th, 2016 and was allowed to burn until July 14th. The fracking fire and contaminates spread to areas north and south of the fracking pad, burning Juniper trees within 200 feet of residential buildings. This fire is not the only documented case in the Greater Chaco Area where communities were disrupted and evacuated in the middle of the night. While community members remain concerned about their health, WPX reported that the incident was not an emergency and that no damage was caused to groundwater.

Drone surveys of this particular site show Cyclone 32, a 1500 Horsepower 755 ton drill rig manufactured in Wyoming. The drill rig is transported through Greater Chaco communities on small dusty single lane dirt roads used by the community members and school buses. The drilling is heard and seen moving from pad to pad. The rig is establishing multiple drill heads on pockets of land tucked along the Kimbeto Wash, a tributary to the Chaco River and sacred source of water security for members of the Greater Chaco Area in Nageezi, New Mexico.

Drone surveys show Lybrook Elementary School only 1600ft from a WPX Energy fracking site. The crude oil tanks of the site can be seen from the classroom windows of the school. The elementary school was moved to this location in 2006 because it was right across the highway from a large and expanding natural gas plant and had to relocate elementary students to a safe location.

Although the WPX Energy site is established on federal land, this area of Counselor, New Mexico is referred to as ‘The Checkerboard’ because of the quadrants of federal land that break up tribal land. The 5 well heads are highlighted to show that these pockets of federal land are being fracked with a high concentration of fracking wells. By drilling multiple wells in one pad location fracking companies are able to quickly drain the plays of crude oil under the the Greater Chaco Area and avoid signing contracts with the native property owners that live and attend school in the area they are fracking.

Drone surveys show crude oil being fracked within 840 ft of an indigenous community in Sandoval County, NM (Greater Chaco). The fracking site is located in the path of the community water supply, which had to be routed around the wellhead and crude tanks. The underground water line remains only 110 ft from active fracking activity.

Particular communities in Greater Chaco are dependent upon pastoral industry and the health of their livestock. Horses owned by the indigenous community are seen grazing on open and unprotected fracking pads. Many of these fracking pads have recorded spills of either fracking fluid, wastewater, or crude oil and pose health risks to the livestock grazing on potentially contaminated grasses and wastewater.

A Western Refining (WPX) crude truck can be seen driving down the community road. These dirt roads were designed to support local community traffic and school buses but are now heavily used by the fracking industry. 90,000-lb gross weight oilfield trucks haul the volatile crude oil through pastoral lands, endangering livestock and community members. Fracking companies continue to level dirt roads to accommodate the weight of their crude trucks. The practice cuts roads deep into the landscape. Roads in Greater Chaco now resemble trenches and make travel dangerous, block scenic views of ancestral land, and hinder the ability to monitor livestock and fracking development.

Drone surveys show 3 well heads, crude tanks, and compressors north of Hwy 550 in Nageezi, NM. The location is of importance because it shows how flaring is used to burn off methane caused by fracking and the transportation processes of crude oil. The River Healers droned this site when workers were not present and the flare tower was turned off for safety concerns, but the flame can usually be seen all the way from Hwy 550 tucked into the distinct hills of the Bisti Badlands. Such methane hotspots are of concern because methane causes severe health risks for individuals living near crude oil facilities. NASA has identified two large methane gas clouds in new Mexico. The methane gas is concentrated above fracking occurring in the San Juan Basin and Permian Basin and disproportionately affects the air quality of Greater Chaco, Four Corners Region, Farmington, and South East region of New Mexico.

Two unlined wastewater pits can be seen on the edge of the fracking pad near the well heads and compressors. Erosion caused by water drainage can be seen leading from the well heads and compressor areas directly to the wastewater pits. Drainages can also be seen coming directly out of the waste water pits and going into the Upper Kimbeto Wash, a tributary of the Chaco River. It is illegal for fracking companies to keep fracking wastewater in unlined pits in the state of New Mexico. The River Healers reported this possible water violation to the EMNRD Oil Conservation Division (a state regulatory body for the fracking industry). EMNRD replied that WPX Energy maintains that the wastewater is caused by stormwater runoff and contains no fracking contaminates. This is the first time we have heard of the fracking industry creating stormwater runoff pits and find the practice to be unusual. Further skepticism that these runoff pits are not contaminated comes from research about the site. In June of 2016, WPX Energy reported a spill of 600 gallons of crude oil at this site because of a fire. WPX maintains that no groundwater was impacted and marked the incident as not an emergency.

Forest fragmentation in PA

Forest Fragmentation and O&G Development in PA’s Susquehanna Basin

/by

In this forest fragmentation analysis, FracTracker looked at existing vegetation height in the northern portion of Pennsylvania’s Susquehanna River Basin. The vegetation height data is available from LANDFIRE, a resource used by multiple federal agencies to assess wildfire potential by categorizing the vegetation growth in 30 by 30 meter pixels into different categories. In the portion of Pennsylvania’s Susquehanna Basin where we looked, there were 29 total categories based on vegetation height. For ease of analysis, we have consolidated those into eight categories, including roads, developed land, forest, herbs, shrubs, crops, mines and quarries, and open water.

Methods

We compared the ratio of the total number of each pixel type to the type that was found at vertical and horizontal wells in the region. In this experiment, we hypothesized that we would see evidence of deforestation in the areas where oil and gas development is present. Per our correspondence with LANDFIRE staff, the vegetation height data represents a timeframe of about 2014, so in this analysis, we focused on active wells that were drilled prior to that date. We found that the pixels on which the horizontal wells were located had a significantly different profile type than the overall pixel distribution, whereas conventional wells had a more modest departure from the general characteristics of the region.

Figure 1 - Vegetation profile of the northern portion of Pennsylvania's Susquehanna River Basin. The area is highly impacted by O&G development, a trend that is likely to continue in the coming years.

Figure 1 – Vegetation profile of the northern portion of Pennsylvania’s Susquehanna River Basin. The area is highly impacted by O&G development, a trend that is likely to continue in the coming years.

In Figure 1, we see that the land cover profile where vertical wells (n=6,198) are present is largely similar to the overall distribution of pixels for the entire study area (n=40,897,818). While these wells are more than six times more likely to be on areas classified as mines, quarries, or barren, it is surprising that the impact is not even more pronounced. In terms of forested land, there is essentially no change from the background, with both at about 73%. However, the profile for horizontal wells (n=3,787) is only 51% forested, as well as being four times more likely than the background to be categorized as herbs, which are defined in this dataset as having a vegetation height of around one meter.

Why Aren’t the Impacts Even More Pronounced?

While the impacts are significant, particularly for horizontal wells, it is a bit surprising that evidence of deforestation isn’t even more striking. We know, for example, that unconventional wells are usually drilled in multi-well pads that frequently exceed five acres of cleared land, so why aren’t these always classified as mines, quarries, and barren land, for example? There are several factors that can help to explain this discrepancy.

First, it must be noted that at 900 square meters, each pixel represents almost a quarter of acre, so the extent of these pixels will not always match with the area of disturbance. And in many cases, the infrastructure for older vertical wells is completely covered by the forest canopy, so that neither well pad nor access road is visible from satellite imagery.

The map above shows horizontal and vertical wells in a portion of Centre County, Pennsylvania, an area within our study region. Note that many of the vertical wells, represented by purple dots, appear to be in areas that are heavily forested, whereas all of the horizontal wells (yellow dots) are on a defined well pad in the lower right part of the frame. Panning around to other portions of Centre County, we find that vertical wells are often in a visible clearing, but are frequently near the edge, so that the chances of the 30 by 30 meter pixel that they fall into is much more likely to be whatever it would have been if the well pad were not there.

We must also consider that this dataset has some limitations. First of all, it was built to be a tool for wildfire management, not as a means to measure deforestation. Secondly, there are often impacts that are captured by the tool that were not exactly on the well site. For this reason, it would make sense to evaluate the area around the well pad in future versions of the analysis.

Figure 2 – A close up of a group of wells in the study area. Note that the disturbed land (light grey) does not always correspond exactly with the well locations.

In Figure 2, we see a number of light grey areas –representing quarries, strip mines, and gravel pits –with an O&G well just off to the side. Such wells did not get classified as being on deforested land in this analysis.

And finally, after clarifying the LANDFIRE metadata with US Forest Service personnel involved in the project, we learned that while the map does represent vegetation cover circa 2014, it is actually build on satellite data collected in 2001, which has subsequently been updated with a detailed algorithm. However, the project is just beginning a reboot of the project, using imagery from 2015 and 2016. This should lead to much more accurate analyses in the future.

Why Forest Fragmentation Matters

The clearing of forests for well pads, pipelines, access roads, and other O&G infrastructure that has happened to date in the Susquehanna Basin is only a small fraction of the planned development. The industry operates at full capacity, there could be tens of thousands of new unconventional wells drilled on thousands of well pads in the region through 2030, according to estimates by the Nature Conservancy. They have also calculated an average of 1.65 miles of gathering lines from the well pad to existing midstream infrastructure. With a typical right-of-way being 100 feet wide, these gathering lines would require clearing 20 acres. It isn’t unusual for the total disturbance for a single well pad and the associated access road to exceed ten acres, making the total disturbance about 30 acres per well pad. Based on the vegetation distribution of the region, we can expect that 22 of these acres, on average, are currently forested land. Taking all of these factors into consideration, a total disturbance of 100,000 to 200,000 acres in Pennsylvania’s Susquehanna River Basin due to oil and gas extraction, processing, and transmission may well be a conservative estimate, depending on energy choices we make in the coming years.

This forest fragmentation has a number of deleterious effects on the environment. First, many invasive plant species, such as bush honeysuckle and Japanese knotweed, tend to thrive in recently disturbed open areas, where competing native plants have been removed. The practice also threatens numerous animal species that thrive far from the forest’s edge, including a variety of native song birds. The disturbed lands create significant runoff into nearby rivers and streams, which can have an impact on aquatic life. And the cumulative release of carbon into the atmosphere is staggering – consider that the average acre of forest in the United States contains 158,000 pounds of organic carbon per acre. As the area is 73% forested, the total cumulative impact could result in taking 5.8 to 11.6 million tons of organic carbon out of forested storage. Much of this carbon will find its way into the atmosphere, along with the hydrocarbons that are purposefully being extracted from drilling operations.
