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.

riverhealers-pic-1

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.

Allegheny County, PA – Drilling, Leasing, and Zoning Trends

/by

By Kirk Jalbert, Manager of Community-Based Research and Engagement
and Matt Kelso, Manager of Data and Technology

FracTracker recently updated its Pennsylvania Shale Viewer to reflect the latest data on unconventional oil and gas permits and active wells in the state. Within this data, we noticed an increase in permitting over the past year for Allegheny County, PA. We have worked on a number of recent initiatives aimed at expanding conversations about unconventional oil and gas drilling by mapping mineral rights leasing and zoning ordinances in Allegheny County. In this article, we bring these various analyses together.

The analysis below can assist residents and public officials in preparing for what appears to be a pending wave of new development.

Untapped Reserves

Over the past decade, unconventional oil and gas development has predominantly occurred in areas where shale formations are densest and most productive. For instance, the map below illustrates wells and permits in Southwestern Pennsylvania that track along the Marcellus Shale. An outlier on the map is Allegheny County when compared to its neighbors such as Washington and Greene Counties just to the south—two of the most drilled in the Commonwealth.

swpa_ac_og

Unconventional wells and permits in Southwest Pennsylvania

A few factors may explain these spatial anomalies. First, oil and gas companies are generally reluctant to operate in heavily populated areas. This is partly due to the complications of acquiring leases and easements in tightly packed communities.

Infrastructure is second consideration. In the absence of compressor stations and midstream pipelines, companies can’t get their product to market.

A third factor is the stronger political opposition often found in urban centers. For example, Pittsburgh’s 2010 fracking ban pushed back against drillers and had a chilling effect in bordering municipalities. Many of Allegheny County’s municipalities have, thus, had the luxury of putting oil and gas-related land use decisions on the back burner. Nevertheless, operators have maintained interest in extracting untapped shale reserves that lie beneath their borders.

Recent Permitting & Drilling Trends

Within Allegheny County, PA, there are now 24 well pads containing a combined 248 permitted wells, of which 109 currently have an active status. On average, these numbers show a 20% increase in well permits annually (40-50 per year) since 2014. This figure compares to less than 10 per year prior to 2012. Furthermore, while only partway through 2017, we’ve already reached this 20% increase in new permits (41 since 8/24), with the overwhelming number of these being issues for Findlay and Forward Townships. A table and graph of permitting activity since 2008 is seen below.

ac_permits_table_08242017

ac_permits_graph_08242017

Table and graph of permitted wells in Allegheny County

Interestingly, the number of active wells over the past few years does not track with increasing number of permits. In fact, active wells peaked in 2014-2015 and have steadily declined since, as is seen in the table and graph below. We credit these opposing trends to operators placing their wells into inactive status during a period of lower gas prices. Meanwhile, operators are increasing their applications for new wells in preparation for a predicted rebound as well as new pipelines and processing facilities coming online for delivering to new markets.

Table and graph of active wells in Allegheny County

Predicting Development: Mineral Rights Leasing

The locations of permits and active wells are not always good indicators of long-term future development. A better picture can be painted with data on properties leased for eventual drilling. In 2016, FracTracker built the Allegheny County Lease Mapping Project, which revealed the extent of oil and gas leasing agreements across the region. From that work came some interesting findings.

There are 467,200 acres in Allegheny County. We found 63,014 acres (18% of the county) are under some kind of oil and gas agreement – this includes mineral rights leases, as well as other agreement such as pipeline rights of ways. It is important to note that as many as 15% of the records we obtained in executing the project could not be mapped due to missing metadata (many block/lot numbers were no longer provided with online records after 2010), so these are conservative estimates.

The list below shows the top five municipalities found to have the most leases. Of note is how West Deer, North Fayette, and Elizabeth townships all have a significant number of leases, but do not yet register in permitting activity.

Most Leased Municipalities in Allegheny County, PA

  1. West Deer Township (5,325 leases)
  2. North Fayette Township (5,070 leases)
  3. Elizabeth Township (4,070 leases)
  4. Fawn Township (3,872 leases)
  5. Forward Township (3,801)

We also discovered that more than 70% of leased properties were zoned residential or agricultural, despite the fact that unconventional oil and gas development is a highly disruptive and industrialized activity. The list below shows a breakdown of zoning designations.

Leased Properties Zoning

    • Residential (37%)
    • Agricultural (34%)
    • Commercial (23%)
    • Industrial (3%)
    • Other (3%)

Status of Protective Zoning

In 2013, the Pennsylvania Supreme Court upended state laws governing local oil and gas zoning rights with its landmark Robinson Township v. Commonwealth of Pennsylvania decision. The court struck down parts of Act 13 that imposed statewide zoning standards for oil and gas development. Zoning ordinances with stronger ordinances are now being adopted by some townships. However, many others have zoning codes that reflect pre-Robinson language, which allows mineral extraction everywhere, regardless of whether it is a compatible land use.

Drawing the connections between drilling trends, leasing activity, and protective zoning is, therefore, significant. Over the past six months, FracTracker has worked with Food & Water Watch to put our lease mapping data and state drilling data in context with assessments of Allegheny County’s municipal oil and gas zoning ordinances. The map below illustrates these overlaps.

Map of Allegheny County Drilling, Leasing, and Zoning


View map fullscreen | How FracTracker maps work

Analysis

Allegheny County contains 130 municipalities. Food & Water Watch was able to obtain and review zoning codes for 104 of these 130. At least 56 municipalities have no zoning ordinances specific to oil and gas development. Of greatest concern, when placed in context with leasing and permitting data, FracTracker found that leases already existed in 43 of these 56 municipalities without oil and gas ordinances, although 8 of these 43 were found to have other less restrictive language regulating specific oil and gas activities, such as seismic testing. Fawn Township, one of the most permitted and most leased municipalities in the county, was found to have no oil and gas zoning ordinance.

Conclusions

It’s important to recognize that there is a significant difference between conventional oil and gas development and today’s heavily industrialized unconventional extraction industry. In many of Allegheny County’s municipalities there seems to be a presumption that there is no need to prepare zoning codes for drilling, despite data that suggest increased oil and gas development may be just around the corner.

With the deeper understanding of Allegheny County’s permitting trends, leasing activities, and the state of protective zoning presented in this article, municipalities would be wise to assess where they stand. Reviewing and updating their respective zoning codes to determine if they sufficiently address concerns related to unconventional drilling could be the most effective way to protect the interests of their residents.

Mariner East 2 Drilling Fluid Spills – Updated Map and Analysis

/by

Updated 8/2/17: An analysis by FracTracker and the Clean Air Council finds that approximately 202,000 gallons of drilling fluids have been accidentally released in 90 different spill events while constructing the Mariner East 2 pipeline in Pennsylvania. In a more recent update, FracTracker estimates these occurred at 42 distinct locations. Explore the map of these incidents below, which we have updated to reflect this growing total.

Last week, a judge with the PA Environmental Hearing Board granted a two week halt to horizontal directional drilling (HDD) operations pertaining to the construction of Sunoco Logistics’ Mariner East 2 (ME2) pipeline. The temporary injunction responds to a petition from the Clean Air Council, Mountain Watershed Association, and the Delaware Riverkeeper Network. It remains in effect until a full hearing on the petition occurs on August 7-9, 2017.

ME2 is a 350-mile long pipeline that, when complete, will carry 275,000 barrels of propane, ethane, butane, and other hydrocarbons per day from the shale gas fields of Western Pennsylvania to a petrochemical export terminal located on the Delaware River.

The petition relates to a complaint filed by the three groups detailing as many as 90 “inadvertent returns” (IRs) of drilling fluids and other drilling related spills along ME2’s construction route. IRs refer to incidents that occur during HDD operations in which drilling fluids consisting of water, bentonite clay, and some chemical mixtures used to lubricate the drill bit, come to the surface in unintended places. This can occur due to misdirected drilling, unanticipated underground fissures, or equipment failure.

Mapping Inadvertent Returns

me2_ir_legendThe Pennsylvania Department of Environmental Protection (DEP) posted information on potential regulatory violations associated with these IRs on the PA Pipeline Portal website on July 24, 2017. This original file listed 49 spill locations. Our original map was based on those locations. As part of their legal filing, volunteer at the Clean Air Council (CAC) have parsed through DEP documents to discover 90 unique spills at these and other locations. On July 31, 2017, the DEP posted a new file that now lists 61 spills, which account for some of these discrepancies but not all.

Working with the CAC, we have created a map, seen below, of the 90 known IRs listed in the DEP documents and from CAC’s findings. Also on the map are the locations of all of ME2’s HDD boring locations, pumping stations, and workspaces, as well as all the streams, ponds, and wetlands listed in Sunoco’s permits as implicated in the project’s construction (see our prior article on ME2’s watershed implications here). Open the map full-screen to see many of these features and their more detailed information.

Analysis Results for ME2

From our analysis, we find that, conservatively, more than 202,000 gallons of drilling fluids have been accidentally released while constructing the Mariner East 2 pipeline in Pennsylvania since the first documented incident on May 3rd. We say conservatively because a number of incidents are still under investigation. In a few instances we may never know the full volume of the spills as only a fraction of the total drilling muds lost were recovered.

We analyzed where these 90 spills occurred relative to known HDD sites and estimate that there are 38 HDDs implicated in these accidents. An additional 11 spills were found at sites where the DEP’s data shows no HDDs, so we calculate the total number of “spill locations” at 42. A full breakdown by county and known gallons spilled at these locations is seen below.

County Number of IRs/Spills Gallons Spilled
Allegheny 4 2,050
Berks 3 540
Blair 3 2,400
Chester 4 205
Cumberland 32 162,330
Delaware 8 2,380
Huntingdon 1 300
Lancaster 7 5945
Lebanon 1 300
Washington 9 4,255
Westmoreland 17 21,532
York 1 25
Total 90 202,262

 

A few important notes on our methods and the available data we have to work with:

  1. CAC obtained spills from DEP incident reports, inadvertent return reports, and other documents describing spills of drilling fluid that have occurred during Mariner East 2 construction.  Those documents reflected incidents occurring between April 25, 2017 and June 17, 2017. In reviewing these documents, volunteers identified 61 discrete spills of drilling fluid, many of which happened at  similar locations. Unfortunately, separate coordinates and volumes were not provided for each spill.
  2. When coordinates were not provided, approximate locations of spills were assigned where appropriate, based on descriptions in the documentation. Two IRs have no known location information whatsoever. As such, they are not represented on the map.
  3. Spill volumes were reported as ranges when there was inconsistency in documentation regarding the same spill. The map circles represent the high-end estimates within these ranges. Of the 90 known spills, 29 have no volume data. These are represented on the map, but with a volume estimate of zero until more information is available.
  4. All documentation available to CAC regarding these spills was filed with the Environmental Hearing Board on July 19, 2017. DEP subsequently posted a table of inadvertent returns on its website on July 24, 2017.  Some of those spills were the same as ones already identified in documents CAC had reviewed, but 29 of the spills described on the DEP website were ones for which CCAC had never received documentation, although a subset of these are now listed in brief in the DEP spreadsheet posted on July 31, 2017. In total then, the documentation provided to CAC from DEP and spreadsheets on the DEP website describe at least 90 spills.

HDD Implications

The DEP’s press release assures the public that the drilling fluids are non-toxic and the IRs are “not expected to have any lasting effects on impacted waters of the commonwealth.” But this is not entirely the case. While the fluids themselves are not necessarily a public health threat, the release of drilling fluids into aquifers and drinking wells can make water unusable. This occurred in June in Chester County, for example.

More commonly, drilling fluid sediment in waterways can kill aquatic life due to the fine particulates associated with bentonite clay. Given that HDD is primarily used to lay pipe under streams, rivers, and ponds (as well as roads, parks, and other sensitive areas), this latter risk is a real concern. Such incidents have occurred in many of the instances cited in the DEP documents, including a release of drilling muds into a creek in Delaware County in May.

We hope the above map and summaries provide insights into the current risks associated with the project and levels of appropriate regulatory oversight, as well as for understanding the impacts associated with HDD, as it is often considered a benign aspect of pipeline construction.

Risks from Colorado’s Natural Gas Storage and Transmission Systems

/by

Given recent concerns about underground natural gas storage wells (UGS), FracTracker mapped UGS wells and fields in Colorado, as well as midstream transmission pipelines of natural gas that transport the gas from well sites to facilities for processing. Results show that 6,673 Colorado residents in 2,607 households live within a 2.5 mile evacuation radius of a UGS well. Additionally, the UGS fields with the largest number of “single-point-of-failure” high-risk storage wells are also the two fields in Colorado nearest communities.

Worst Case Scenario

A house exploding from a natural gas leak sounds straight out of a 19th century period drama, but this tragedy just recently occurred in Firestone, Colorado. How could this happen in 2017? We have seen pictures and read reports of blowouts and explosions at well sites, and know of the fight against big oil and natural gas pipelines across the country. At the same time we take for granted the natural gas range that heats our food to feed our families. The risk of harm is seemingly far removed from our stove tops, although it may be much closer to home than we think – There are documented occupational hazards and compartmentalized risks in moving natural gas off site.

Natural gas is an explosive substance, yet the collection of the gas from well sites remains largely industry-regulated. Unfortunately, it has become clear that production states like Colorado are not able to provide oversight, much less know where small pipelines are even located. This is particularly dangerous, since the natural gas in its native state is ordorless, colorless, and tasteless. Flowing in the pipelines between well sites and processing stations, natural gas does not contain the mercaptan that gives commercial natural gas its tell-tale odor. In fact, much of the natural gas or “product” is merely lost to the atmosphere, or much worse, can collect in closed spaces and reach explosive levels. This means that high, potentially explosive levels of methane may go undetected until far too late.

Mapping Flow Lines

As a result of the house explosion in Firestone on April 17th CO regulators are now requiring oil and gas operators to report the location of their collection flow pipelines, as shown in Figure 1.

Figure 1. Map of Gathering Pipeline “Flowlines”


View map fullscreen

The locations of the collection of pipeline “flowlines”, like the uncapped pipeline that caused the house explosion in Firestone, have been mapped by FracTracker Alliance (above). The dataset is not complete, as not all operators complied with the reporting deadline set by the COGCC. For residents living in the midst of Colorado’s oil and gas production zones, addresses can be typed into the search bar in the upper left corner of the map. Users can see if their homes are located near or on top of these pipelines. The original mapping was done by Inside Energy’s Jordan Wirfs-Brock.

Underground Storage

When natural gas is mixed with mercaptan and ready for market, operators and utility companies store the product in UGS fields. (EDIT – Research shows that in most cases natural gas in UGS fields is not yet mixed with mercaptan. Therefore leaks may go undetected more easily. Aliso Canyon was a unique case where the gas was being stored AFTER being mixed with mercaptan. Odorization is not legally required until gas moves across state lines in an interstate pipeline or is piped into transmission lines for commercial distribution.) In August 2016, a natural gas storage well at the SoCal Gas Aliso Canyon natural gas storage field failed causing the largest methane leak in U.S. history. The Porter Ranch community experienced health impacts including nosebleeds, migraines, respiratory and other such symptoms. Thousands of residents were evacuated. While Aliso Canyon was the largest leak, it was by no means a unique case.

FracTracker has mapped the underground natural gas storage facilities in Colorado, and the wells that service the facilities. As can be seen below, there are 10 storage fields in Colorado, and an 11th one is planned. All the fields used for storage in Colorado are previously depleted oil and gas production fields. The majority of storage wells used to be production wells. All sites are shown in the map below (Figure 2).

Figure 2. Map of Natural Gas Underground Storage Facilities

Impacted Populations

Our analysis of Colorado natural gas storage facilities shows that 6,673 Colorado residents living in 2,607 households live within a 2.5 mile evacuation radius of a UGS well. The majority of those Coloradans (5,422) live in Morgan County, with 2,438 in or near the city of Fort Morgan. The city of Fort Morgan is surrounded by the Young Gas Storage Facility with a working capacity of 5,790,049 MCF and Colorado Interstate Gas Company with a working capacity of 8,496,000 MCF.

By comparison, the failure in Aliso Canyon leaked up to 5,659,000 MCF. A leak at either of these facilities could, therefore, result in a similar or larger release.

UGS Well Risk Assessment

A FracTracker co-founder and colleague at Harvard University recently completed a risk assessment of underground natural gas storage wells across the U.S. The analysis identified the storage wells shown in the map above (Figure 1) and defined a number of “design deficiencies” in wells, including “single-point-of-failure” designs that make the wells vulnerable to leaks and failures. Results showed that 2,715 of the total 14,138 active UGS wells across the country were constructed using similar techniques as the Aliso Canyon failed well.

Applying this assessment to the wells in Colorado, FracTracker finds the following:

  • There are a total of 357 UGS wells in Colorado.
  • 220 of which are currently active.
  • Of those 220 UGS wells, they were all drilled between 1949 and 1970.
  • 43 of the UGS wells are repurposed production wells.
  • 40 of those repurposed wells are the highest risk single barrier wells.

Specifically focusing on the UGS fields surrounding the city of Fort Morgan:

  • 21 single barrier wells are located in the Flank field 2.5 miles North of the city.
  • 13 single barrier wells are located in the Fort Morgan field 2.5 miles South of the city.

We originally asked how something as terrible as Firestone could have occurred. Collectively we all want to believe this was an isolated incident. Sadly, the data suggest the risk is higher than originally thought: The fields with the largest number of “single-point-of-failure” high-risk UGS wells are also the two fields in Colorado nearest communities. While the incident in Firestone is certainly heartbreaking, we hope regulators and operators can use the information in this analysis to avoid future catastrophes.

Recent Changes to Pennsylvania Maps

/by

Recently, the Pennsylvania Department of Environmental Protection (DEP) started to offer additional data resources with the introduction of the Open Data Portal. This development, along with the continued evolution of the ArcGIS Online mapping platform that we utilize has enabled some recent enhancements in our mapping of Pennsylvania oil and gas infrastructure. We’ve made changes to the existing Pennsylvania Shale Viewer for unconventional wells, and created a Conventional and Historical Wells in Pennsylvania map.

Unconventional Wells

Rather than defining the newer, industrial-scaled oil and gas wells by specific geological formations, configuration of the well, or the amount of fluid injected into the ground during the hydraulic fracturing process, Pennsylvania’s primary classification is based on whether or not they are considered to be unconventional.

Unconventional Wells – An unconventional gas well is a bore hole drilled or being drilled for the purpose of or to be used for the production of natural gas from an unconventional formation. An unconventional formation is defined as a geologic shale formation below the base of the Elk Sandstone or its geologic equivalent where natural gas generally cannot be produced except by horizontal or vertical well bores stimulated by hydraulic fracturing.

PA Shale Viewer (Unconventional Drilling)

View map fullscreen | How FracTracker maps work

The previous structure of the PA Shale Viewer had separate layers for permits, drilled wells, and violations. This version replaces the first two layers with a single layer of unconventional locations, which we have called “Unconventional Wells and Permits” for the sake of clarity. The violations layer appears in the same format as before. When users are zoomed out, they will see generalized layers showing the overall location of O&G infrastructure and violations in the state, which were formed by creating a one mile buffer around these features. As users zoom in, the generalized layers are then replaced with point data showing the specific wells and violations. At this point, users can click on individual points and learn more about the features they see on the map.

PA Shale Viewer Zoomed In

Figure 1. PA Shale Viewer zoomed in to see individual wells by status

O&G locations are displayed by their well status, as of the time that FracTracker processed the data, including: Abandoned, Active, Operator Reported Not Drilled, Plugged OG Well, Proposed but Never Materialized, and Regulatory Inactive Status. Note that just because a well is classified as Active does not mean that it has been drilled, or even necessarily permitted. These milestones, along with whether or not it has been plugged, can be determined by looking for entries in the permit issue date, spud date, and plug date entries in the well’s popup box.

Conventional and Historical Wells

The map below shows known conventional wells in Pennsylvania along with additional well locations that were digitized from historical mining maps.

Conventional Oil and Gas Wells Map

View map fullscreen | How FracTracker maps work

Although there are over 19,000 unconventional oil and gas locations in Pennsylvania, this figure amounts to just 11% of the total number of wells in the state that the DEP has location data for, the rest being classified as conventional wells. Furthermore, in a state that has been drilling for oil and gas since before the Civil War, there could be up to 750,000 abandoned wells statewide.

The DEP has been able to find the location of over 30,000 of these historical wells by digitizing records from old paper mining maps. This layer has records for 16 different counties, but well over half of these wells are in just three counties – Allegheny, Butler, and Washington. It looks like it would take a lot more work to digitize these historical wells throughout the rest of the state, but even when that happens, we will probably still not know where the majority of the old oil and gas wells in the state are located.

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.


View map fullscreen | How FracTracker maps work

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.

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.

How fragmented approvals and infrastructure favor petrochemical development

By Leann Leiter and Lisa Graves-Marcucci

Let’s think back to 2009, when oil and gas companies like Range Resources began drilling the northeast shale plays in earnest. Picture the various stages involved in drilling – such as leasing of land, clearing of trees, boring of wells, siting of compressor stations, and construction of pipelines to gather the gas. Envision the geographic scope of the gas infrastructure, with thousands of wells in Pennsylvania alone, and thousands of miles of pipelines stretching as far as Louisiana.

Now, picture the present, where a homeowner looks out over her yard and wonders how a lease she signed with Shell several years prior made it possible for the company to run an ethane pipeline across her property and between her house and her garage.

Think forward in time, to 2022, the year when a world-scale ethane cracker is set to go online in Beaver County, Pennsylvania, to begin churning through natural gas liquids from wells in PA and others, producing a variety of disposable plastic products.

At each of these moments in gas development, which of the many stakeholders – industry leaders, local governments, state regulatory agencies, or landowners and residents – were granted a view of the full picture?

The proposed Shell ethane cracker in Beaver County is an illustration of the fragmented nature of gas development. From the extensive web of drilling infrastructure required to supply this massive facility, to several years of construction, this project is a case-study in piecemeal permitting. Such fragmentation creates a serious barrier to transparency and to the informed decision-making that relies upon it.

In the first two articles in this series on the petrochemical development in Beaver County, we focused on ethane cracker emergency scenarios and how the area might prepare. In this article, we draw the lens back to take in the larger picture of this region-altering project and highlight the effects of limited transparency.

The “Piecemeal” Nature of Gas Development

All across the Pennsylvania, proposed industrial development – even coal operations – have historically provided to the public, elected officials, and regulatory agencies the extent or footprint of their planned operations. Nonetheless, the oil and gas industry has in several instances undertaken a practice of developing its extensive infrastructure piece-by-piece. Operators of these facilities first acquire a GP-5 General Permit, which is only available to certain oil and gas operations with “minor” emissions and which allows them to avoid having the permit undergo public notice or comment. These operators then add emissions sources and increases through a series of minor amendments. While they are required to obtain a “major” source permit once their modifications result in major emissions, they avoid the scrutiny required for a major source by this fragmented process.

Unlike most other industrial permitting, the gas industry has enjoyed a much less transparent process. Instead of presenting their entire planned operation at the time of initial permit application, gas operators having been seeking – and receiving – incremental permits in a piecemeal fashion. This process puts local decision makers and the women, men, and children who live, work, and go to school near gas development at a severe disadvantage in the following ways:

  • Without full disclosure of the entirety of the planned project, neither regulatory bodies nor the public can conduct a full and factual assessment of land use impacts;
  • Incremental approvals allow for ever-expanding operations, including issuance of permits without additional public notification and participation;
  • Piecemeal approvals allow operations to continuously alter a community and its landscape;
  • The fragmented approval process prevents consideration of cumulative impacts; and
  • Without full transparency of key components of the proposed operations, emergency planning is hampered or non-existent.

From the Well to the Ethane Cracker

In the fragmented approval process of gas development, the proposed ethane cracker in Beaver County represents a pertinent example. Developers of this massive, multi-year, and many-stage project have only revealed the size and scope in a piecemeal fashion, quietly making inroads on the project (like securing land leases along the route of the pipeline required for the cracker, years in advance of permit approvals for the facility itself). By rolling out each piece over several years, the entirety of the petrochemical project only becomes clear in retrospect.

A World-Scale Petrochemical Hub

While Shell is still pursuing key approval from the PA Department of Environmental Protection, industry leaders treat the ethane cracker as a foregone conclusion, promising that this facility is but one step in turning the area into a “petrochemical hub.”

The cracker facility, alone, will push existing air pollution levels further beyond their already health-threatening state. Abundant vacant parcels around Shell’s cracker site are attractive sites for additional spin-off petrochemical facilities in the coming “new industry cluster.” These facilities would add their own risks to the equation, including yet-unknown chemical outputs emitted into the air and their resulting cumulative impacts. Likewise, disaster risks associated with the ethane cracker remain unclear, because in the piecemeal permitting process, the industry is not required to submit Preparedness, Prevention, and Contingency (PPC) Plans until after receiving approval to build.

92.3 Miles of Explosive Pipeline

More than just a major local expansion, communities downriver and downwind will be susceptible to the impacts, including major land disturbance, emissions, and the potential for “incidents,” including explosion. The pipeline required to feed the cracker with highly flammable, explosive ethane would tie the tri-state region into the equation, expanding the zone of risk into Ohio and crossing through West Virginia.

Renewed Demand at the Wellhead

No one piece of the gas infrastructure stands alone; all work in tandem. According to the  Energy Information Administration (EIA), the new US ethane crackers will drive consumption of ethane up by a 26% by the end of 2018. Gas wells in the northeast already supply ethane; new ethane crackers in the region introduce a way to profit from this by-product of harvesting methane without piping it to the Gulf Coast. How this renewed demand for ethane will play out at fracked wells will be the result of complex variables, but it will undoubtedly continue to drive demand at Pennsylvania’s 10,000 existing unconventional oil and gas wells and those of other states, and may promote bringing new ones online.

Figure 4. Excerpt from Executive Summary of IHS Markit Report, “Prospects to Enhance Pennsylvania’s Opportunities in Petrochemical Manufacturing.”

Along with drilling comes a growing network of gathering and transmission lines, which add to the existing 88,000 miles of natural gas pipeline in Pennsylvania alone, fragment wildlife habitat, and put people at risk from leaks and explosions. Facilities along the supply stream that add their own pollution and risks include pump stations along the route and the three cryogenic facilities at the starting points of the Falcon Pipeline (see Fig. 6).

The infrastructure investment required for ethane crackers in this region could reach $3.7 billion in processing facilities, pipelines for transmitting natural gas liquids including ethane, and storage facilities. A report commissioned by Team Pennsylvania and the PA Department of Community and Economic Development asserts that “the significant feedstock and transportation infrastructure required” will “exceed what is typically required for a similar facility” in the Gulf Coast petrochemical hub, indicating a scale of petrochemical development that rivals that of the southern states. This begs the question of how the health impacts in Pennsylvania will compare to those in the Gulf Coast’s “Cancer Alley.”

Water Impacts, from the Ohio River to the Arctic Ocean

Shell’s facility is only one of the ethane crackers proposed for the region that, once operational, would be permitted to discharge waste into the already-beleaguered Ohio River. This waterway, which traverses six separate states, supplies the drinking water for over 3 million people. Extending the potential water impact even further, the primary product of the Shell facility is plastics, whose inevitable disposal would unnecessarily add to the glut of plastic waste entering our oceans. Plastic is accumulating at the alarming rate of 3,500 pieces a day on one island in the South Pacific and as far away as the waters of the Arctic.

How does fragmentation favor industry?

The gas and petrochemical industry would likely defend the logistical flexibility the piecemeal process affords them, allowing them to tackle projects, make investments, and involve new players as needed overtime. But in what other ways do the incredibly fragmented approval processes, and the limited requirements on transparency, favor companies like Shell and their region-changing petrochemical projects? And what effect does the absence of full transparency have on local communities like those in Beaver County? We conclude that it:

  • “Divides and conquers” the region. The piecemeal approach to gas development, and major projects like the Shell ethane cracker, deny any sense of solidarity between the people along the pipeline route resisting these potentially explosive channels cutting through their yards, and residents of Beaver County who fear the cracker’s emissions that will surround their homes.
  • Makes the project seem a foregone conclusion, putting pressure on others to approve. For example, before Shell formally announced its intention to build the facility in Potter Township, it rerouted a state-owned road to facilitate construction and increased traffic flow. Likewise, though a key permit is still outstanding with the PA DEP, first responders, including local volunteer firefighters, have already begun dedicating their uncompensated time to training with Shell. While this is a positive step from a preparedness standpoint, it is one of many displays of confidence by Shell that the cracker is a done deal.
  • Puts major decisions in the hands of those with limited resources to carry them out and who do not represent the region to be affected. In the case of the Shell ethane cracker, three township supervisors in Potter Township granted approvals for the project. The impacts, however, extend well beyond Potter or even Beaver county and include major air impacts for Allegheny County and the Pittsburgh area. Effects will also be felt by landowners and residents in numerous counties and two states along the pipeline route, those near cryogenic facilities in Ohio and Pennsylvania, plus those living on the Marcellus and Utica shale plays who will see gas well production continue and potentially increase.

Fragmented Transparency, Compromised Decision-making

The piecemeal, incremental, and fragmented approval processes for the ethane cracker – and other gas-related facilities in the making – create one major problem. They make it nearly impossible for locals, elected officials, and regulatory agencies to see the whole picture as they make decisions. The bit-by-bit approach to gas development amounts to far-reaching development with irreversible impacts to environmental and human health.

We ask readers, as they contemplate the impacts closest to them – be it a fracked well, a hazardous cryogenic facility, the heavily polluted Ohio River, a swath of land taken up for the pipeline’s right-of-way, or Shell’s ethane cracker itself – to insist that they, their elected officials, and regulators have access to the whole picture before approvals are granted. It’s hard to do with a project so enormous and far-reaching, but essential because the picture includes so many of us.

Wayne National Forest Could Be Deforested – Again

/by

Guest article by Becca Pollard

Eighty years ago, Southeastern Ohio was a wasteland of barren, eroding hills. During the 18th and 19th centuries this once heavily forested area in the Appalachian foothills had been clear cut and mined beyond recognition. When the Great Depression struck, lowering crop prices made farming unprofitable in the area, and 40% of the population moved away.

In 1933, President Franklin Delano Roosevelt established the Civilian Conservation Corps (CCC), a public work relief program that employed men aged 18-25 to do manual labor related to conservation and development of natural resources such as planting trees, constructing trails, roads, and lodges, fighting wildfires, and controlling erosion. The following year, Ohio’s legislature agreed to allow the federal government to purchase land in the state for the purpose of establishing a national forest. The Forest Service was tasked with restoring the land for what is now called Wayne National Forest (WNF). A tree nursery was established near Chillicothe, and with the help of the CCC and volunteers, including members of the Daughters of the American Revolution, garden clubs, and school children, reforestation began.

An Area on the Mend

Today, WNF comprises three units that span 12 Ohio counties in the Unglaciated Allegheny Plateau. The hills are covered in biologically diverse mixed mesophytic forest, which includes approximately 120 species of trees and provides habitat for at least 45 species of mammals, 158 species of birds, 28 species of reptiles, 29 species of amphibians, and 87 species of fish. The US Forest Service estimates that 240,000 people visit this ecological wonder annually, according to Forest Recreation Program Manager, Chad Wilberger, in Nelsonville, Ohio. The restoration of barren public land to its current state is a great achievement. If it continues to be protected, Wayne could one day resemble the old growth forest that thrived here before the arrival of European settlers.

The Bureau of Land Management (BLM), however, has recently decided to lease up to 40,000 acres of Wayne to gas and oil companies for horizontal hydraulic fracturing, or fracking. The first auction took place last December resulting in the lease of 700 acres. A second auction this March leased another 1,200 acres. Nearly all of this land lies within the 60,000 acre Marietta Unit of the forest. This brings Oil & Gas Expressions of Interest (EOI) acreage to roughly 7.5% of all WNF owned parcels in this unit.

Not new, not old

Gas and oil development is not new to the Wayne. Since the passage of The Federal Land Policy and Management Act of 1976, the US Forest Service’s land management plan for WNF has included conventional drilling, and derricks are a common sight on both public and private land in southeastern Ohio.

Fracking (unconventional drilling), however, has a far greater impact, requiring clear cutting of large areas of land for the construction of concrete well pads, and the use of millions of gallons of water that will become contaminated during the process and then transported by truck to injection wells. Accidents can be catastrophic for workers and nearby residents, and fracking and waste water disposal have been linked to earthquakes in Ohio.

In 2012, BLM updated its WNF Land and Resource Management Plan to allow fracking in the forest without conducting new impact studies.

What is at risk?

The Marietta Unit of the WNF is located in Monroe, Perry, and Washington counties in Southeastern Ohio along the Ohio River. Within its boundary are a wealth of trails used for hiking, backpacking, horseback riding, and mountain biking, campgrounds, and waterways ideal for kayaking and fishing. Both the highest and lowest points in the Wayne lie in this unit, as does the Irish Run Natural Bridge. The area is also known for its exceptional wildflowers, as shown in the photos below.

Woodland Stonecrop (Sedum ternatum) in Wayne National Forest

One popular recreation area, Lamping Homestead, lies directly within an oil and gas Expression Of Interest (EOI) parcel #3040602400 (See Map Above), one of the areas under consideration for lease. In the 1800s, it was the site of the Lamping family’s farm, but today all that remains of the settlers is a small cemetery with an iron gate atop a hill overlooking a small lake. Six campsites are situated around the western side of the lake, and two intersecting hiking loops rise into the wooded hills to the east. On the western side of the parking lot is a covered picnic area. A creek flows out of the lake and into Clear Fork, a tributary of the Little Muskingum River, across the road from the parking lot.

Both the lake and stream are popular boating and fishing areas. Lamping is an excellent spot for wildlife viewing. The lake, the creeks that flow in and out of it, and the surrounding wooded hills support an impressive variety of plant and animal species. During the day, visitors might spot ducks, geese, great blue herons, red-winged blackbirds, summer tanagers, red spotted newts, box turtles, northern water snakes, garter snakes, deer, rabbits, and muskrats. At night, they could be greeted by a cacophony of voices from frogs, owls, and coyotes.

Species of trees, plants, and fungus are also numerous. In winter, stands of white pine pop out against the bare branches of oak, hickory, maple, buckeye, and other deciduous trees. In spring, eye-catching splotches of blooming dogwood and redbud contrast against the many shades of green. But hikers who pull their gaze away from the brightly colored canopy and look down are rewarded with an abundance of wildflowers and the butterflies they attract, as well as many varieties of mushrooms and fungus, including such edible varieties as morels, wood ear, and dryad’s saddle.

Estimating Disturbances

It is unclear how much surface disturbance would occur on public land if this parcel were to be fracked, but even if the well pad and pipelines were constructed on private land adjacent to the forest, in order to drill under the forest, the public land and its inhabitants and visitors would certainly be impacted.

There is no question that noise and air pollution from traffic and construction would be disruptive both to wildlife and to human visitors. Explore various photos of the oil and gas industry in the gallery below:

Active Fracking Operation in Belmont County, Ohio

The extraction process requires 2 million to 6 million gallons of fresh water each time a well is fracked. The rate at which hydraulic fracturing’s water demand is increasing on a per-well basis here in Ohio reached an exponential state around Q4-2013 and Q1-2014 and continues to rise at a rate of 3.1 million gallons per well per year (Figure 1).

In Ohio, oil and gas companies are allowed to pull this water directly from streams and rivers at no cost. All this is possible, despite the fact that after its use it is so contaminated that it must be disposed of via injection wells and is permanently removed from the water cycle. The industry is already pulling water from streams in the Marietta Unit of the WNF for use in fracking on private land. Fracking public land simply means water withdrawals will occur on a much larger scale.

Inevitable methane leaks, in addition to contributing to climate change, affect humans and wildlife in their immediate vicinity, causing headaches and nausea and even killing trees and plants.

In addition to the anticipated harm that fracking inflicts upon a natural area, there is also a risk of accidents with potentially devastating consequences. Residents of Monroe County have already seen a few in recent years from fracking on private land. In 2014, a well pad fire in the village of Clarington resulted in a chemical spill that contaminated nearby Opossum Creek, killing 70,000 fish. The same year a large gas leak 15 miles south in the village of Sardis resulted in the evacuation of all homes within half mile radius.

Recent studies have shown that extraction wells, in addition to injection wells, can cause earthquakes. Unsurprisingly, Monroe County has seen a spike in seismic activity with the increase in fracking activity in the area. The most recent incident was a 3.0 magnitude earthquake in the forest less than five miles from Lamping Homestead in April of this year.

Supporters of Wayne National Forest

Many people have repeatedly spoken out against BLM’s plan, submitting a petition with more than 100,000 signatures, and protesting outside Wayne National Forest Headquarters and Athens Ranger Station in Nelsonville. They have even organized voters to call and write letters to Regional Forester Kathleen Atkinson and legislators, including Senators Sherrod Brown and Rob Portman, and Governor John Kasich. BLM has not budged on its decision, unfortunately, insisting that leasing this land for fracking, and associated infrastructure buildout, will have “no significant impact.”

This May, the Center for Biological Diversity, Ohio Environmental Council, Ohio Sierra Club, and Heartwood, a regional organization focused on protecting forests, filed a lawsuit against BLM, aiming to void BLM leases and halt all fracking operations within the national forest.

Concerned citizens continue to organize raise awareness as they await the outcome of the suit.

Underground Gas Storage Wells – An Invisible Risk in the Natural Gas Supply Chain

/by

The largest accidental release of methane in U.S. history began October 23, 2015 with the blowout of an underground natural gas storage well in Aliso Canyon about 20 miles west of Los Angeles. By the time the well was plugged 112 days later, more than 5.0 billion cubic feet of methane and other pollutants had been released to the atmosphere. It was a disaster for the climate, the environment, California’s energy supply, and the more than 11,000 people that were forced to evacuate.

A new study from the Harvard T. H. Chan School of Public Health – Center for Health and the Global Environment shows that more than one in five of the almost 15,000 active underground gas storage (UGS) wells in the US could be vulnerable to serious leaks due to obsolete well designs – similar in design to the well that failed at the Aliso Canyon storage facility.

Published today in the journal Environmental Research Letters, the study presents a national baseline assessment of underground storage wells in the U.S. and indicates the need for a better understanding of the risks associated with the obsolescence of aging storage wells. The study also highlights the widespread nature of certain age-related risk factors, but indicates that some of the highest priority wells may be located in PA, OH, NY, and WV.

The study shows that the average construction year of largely unregulated active UGS wells in the US is 1963, with potentially obsolete wells that were not originally designed for storage operating in 160 facilities across 19 states. Some of the wells were constructed over 100 years ago – a time period that precedes many modern well containment systems such cement isolation and the use of multiple casings. Some of the oldest active UGS wells were not designed for two-way flow of gas, and therefore may not exhibit sufficient material-grade or redundant precautionary systems to prevent containment loss, as was evident at Aliso Canyon.

An Interview with the Author

Sam, Matt, and Kyle of FracTracker caught up with lead author and former FracTracker colleague, Dr. Drew Michanowicz, now with the Center for Health and Global Environment within the Harvard T. H. Chan School of Public Health to find out more about their study.

When we spoke with Drew, he began the interview by posing the first question to us:

Did you know that about 15% of the natural gas produced in the US is injected back into the ground each year?

While we had all heard of underground gas storage before, we had to admit that we never thought of the process like that before. In other words, some of the natural gas in the US is being produced twice from two different reservoirs before being consumed. And because many of these storage systems utilized depleted oil and gas reservoirs, many of the same pre- and post-conditioning processes, such as dehydrating and compressing, are necessary to bring the gas to market.

The following questions and answers from Drew expand upon the study’s findings:

Q: What prompted you and your colleagues to investigate this topic?

A: After the Aliso Canyon incident, we became interested in the question: ‘Is Aliso Canyon Unique?’ Interestingly, there were plenty of early warning signs at that facility that corrosion issues on very old repurposed wells were becoming a significant issue. Almost a year before the well blowout, Southern California gas went on record in front of California’s Public Utility Commission stating that they needed a rate increase to implement a necessary integrity management plan for their wells, and to be able to move beyond operating in a reactive mode. That unfortunately prophetic document really got us interested in better understanding why their infrastructure was in the state it was in. And like any major accident like this, a logical next step is to assess the prevalence of hazardous conditions elsewhere in the system, in the hope to prevent the next one.

From our research, it appears that a very large portion of the UGS sector may be facing similar obsolescence issues compared to Aliso, such as decades-old wells not originally designed for two-way flow. Our work here, however, is a simplified assessment that focused only on passive barriers or the fixed structures such as the steel pipes likely present in a well. Much more work is needed to fully understand the active-type safety measures in place such as safety valves, tubing/packers, and overall integrity management plans – all important factors for manage risks.

Q: We see that your team developed a well-level database of over 14,000 active UGS wells across 29 states. Because data-collation is a big part of our work here, can you describe that data collection process?

A: Very early on we also realized that underground gas storage was exempt from the Safe Drinking Water Act’s Underground Injection Control (UIC) program – similar to exemption with hydraulic fracturing and the Energy Policy Act of 2015, AKA the Halliburton Loophole. This meant in part that very little aggregate well data was available from the Federal Government or by third-party aggregators like FracTracker and DrillingInfo. Reminiscent of my former extreme data-paucity days at FracTracker, we knew we needed to build a database basically from scratch to effectively perform a hazard assessment that incorporated a spatial component.

We began by gathering what data we could from the U.S. Energy Information Administration (EIA), which gave us good detail at the field or facility level, but the fields were generalized to a county centroid. So to fully evaluate these infrastructure, we needed to figure out how to join the facility-level data to the well data for each state. We relied on NETL’s Energy Data eXchange to identify state-level wellbore data providers where applicable. Once we collected all of the state data, we created a decision-tree framework to join the individual wells to the EIA field names in order to produce a functional geodatabase. Because we had to manage data from so many sources, we had to devote quite a bit of effort to data QA/QC, and that is reflected in the methods and results of the paper. For example, some of our fields and wells had to be joined via visual inspection of company system maps, because of missing identifier information.

Q: We see that some of the oldest repurposed wells you mapped are located in PA, OH, NY, and WV. Was that a surprise to you?

A: That was a surprise considering this story started for us in California, and even more surprising was that some are more than 100 years old. Now, a bit of caution here is warranted when thinking about the age of any engineered system. On the one hand, something that functions for a very long time is an indication that the system was very well suited for its task, and likely has been very well taken care of – think of an antique automobile like a fully functional 1916 Model T Ford, for example. On the other hand, age and construction year relates to the integrity of an engineered system through two processes by:

  1. providing information to how long a system has been exposed to natural degradation processes such as corrosion, and stresses from thermal and abrasive cycles; and by
  2. proxying for knowledge and regulatory safety standards at the time of construction which informs the design, materials, technologies likely used.

To go back to the car example, while an old classic car may still be operational, it may not have certain safety features like antilock brakes, airbags, or safety belts, and generally will not be able to go as fast as a modern car. Therefore, a gas storage well’s integrity is at least indirectly related to its construction year when considering the multitude of technological and safety improvements have occurred over the years. This is how we have been thinking about well integrity from a 5,000 foot perspective. Needless to say, more research is needed to understand the causal effect of age on well integrity.

Q: So if we understand you correctly, these older wells can be maintained with sufficient management practices, but there may be inherent safety features missing on these older wells that don’t adhere to todays’ standards?

A: That’s right. So what we can say about some of these aging wells is that some will not reflect certain modern fail-safe engineering such as sufficient casing design strength and multiple casings or barriers along the full length. And these are permanent structural elements vestigial to the well’s original design, and therefore cannot be undone or redesigned away. In other words, it makes much more sense to drill a new well with new materials than attempt to significantly alter an old well. And the gas storage wells built today are designed with redundant fail-safe systems including multiple barriers and real-time pressure sensors.

But back to my earlier point about lack of federal regulations to set a minimum safety standard – because of that, there is also much uncertainty surrounding how many of these facilities have been dealing with safety and risk management. That is a future direction of this work – to really try to fill in some of regulatory gaps between states and the impending Federal guidelines and identify some best practices to help inform policy makers specifically at the state level.

Drew put together a map to highlight where some of these active storage wells are in PA, OH, NY, and WV:

Underground Gas Storage map

This area map of PA, WV, OH, and NY displays where active underground natural gas storage operations are located. The small white points represent active storage wells that have a completion, SPUD, or permit date that occurs after the field was designated for storage indicating that these wells are more likely to have been designed for storage operations. The green points are active storage wells that predate storage operations, indicating that these wells may not have been designed for storage.

There are 121 storage fields connected to at least 6,624 active gas storage wells across these four states. A portion of wells in this region were not included in this final count because they did not contain sufficient status or date information. Pennsylvania has the most individual storage fields of any state with 47, while Ohio boasts the most active storage wells of any state in the country with 3,318 across its 22 active fields. Of the 6,624 active UGS wells across these four states, 1,753 predate storage designation indicating that these wells were likely not originally designed for storage. These ‘repurposed’ wells have a median age of 84 years, with 210 wells constructed over 100 years ago (red points). The 100 year cutoff is not arbitrary, as the year 1917 marks the advent of cement zonal isolation techniques, indicating that these wells may be of the highest priority in terms of design deficiencies related to well integrity, and they are primarily located across the four states pictured above.

Additional Notes

The well that failed at Aliso Canyon was originally drilled in 1954 for oil production. In 1972, it was repurposed for underground gas storage, which entails both production and injection cycles in a single well. The problem seems to be that because it was not originally constructed to store natural gas, only a single steel pipe separated the flow of gas and the outside rock formation. That meant the well’s passive structural integrity was vulnerable to a single point-of-failure along a portion of its casing. When part of the subsurface well casing failed, there were no redundancies or safety valves in place to prevent or minimize the blow out.
