Idle Wells are a Major Risk

Designating a well as “idle” is a temporary solution for operators, but comes at a great economic and environmental cost to Californians 

Idle wells are oil and gas wells which are not in use for production, injection, or other purposes, but also have not been permanently sealed. During a well’s productive phase, it is pumping and producing oil and/or natural gas which profit its operators, such as Exxon, Shell, or California Resources Corporation. When the formations of underground oil pools have been drained, production of oil and gas decreases. Certain techniques such as hydraulic fracturing may be used to stimulate additional production, but at some point operators decide a well is no longer economically sound to produce oil or gas. Operators are supposed to retire the wells by filling the well-bores with cement to permanently seal the well, a process called “plugging.”

A second, impermanent option is for operators to forego plugging the well to a later date and designate the well as idle. Instead of plugging a well, operators cap the well. Capping a well is much cheaper than plugging a well and wells can be capped and left “idle” for indefinite amounts of time.

Well plugging

Unplugged wells can leak explosive gases into neighborhoods and leach toxic fluids into drinking waters. Plugging a well helps protect groundwater and air quality, and prevents greenhouse gasses from escaping and expediting climate change. Therefore it’s important that idle wells are plugged.

While plugging a well does not entirely eliminate all risk of groundwater contamination or leaking greenhouse gases, (read more on FracTracker’s coverage of plugged wells) it does reduce these risks. The longer wells are left idle, the higher the risk of well casing failure. Over half of California’s idle wells have been idle for more than 10 years, and about 4,700 have been idle for over 25 years. A report by the U.S. EPA noted that California does not provide the necessary regulatory oversite of idle wells to protect California’s underground sources of drinking water.

Wells are left idle for two main reasons: either the cost of plugging is prohibitive, or there may be potential for future extraction when oil and gas prices will fetch a higher profit margin.  While idle wells are touted by industry as assets, they are in fact liabilities. Idle wells are often dumped to smaller or questionable operators.

Orphaned wells

Wells that have passed their production phase can also be “orphaned.” In some cases, it is possible that the owner and operator may be dead! Or, as often happens, the smaller operators go out of business with no money left over to plug their wells or resume pumping. When idle wells are orphaned from their operators, the state becomes responsible for the proper plugging and abandonment.

The cost to plug a well can be prohibitively high for small operators. If the operators (who profited from the well) don’t plug it, the costs are externalized to states, and therefore, the public. For example, the state of California plugged two wells in the Echo Park neighborhood of Los Angeles at a cost of over $1 million. The costs are much higher in urban areas than, say, the farmland and oilfields of the Central Valley.

Since 1977, California has permanently sealed about 1,400 orphan wells at a cost of $29.5 million, according to reports by the Division of Oil, Gas, and Geothermal Resources (DOGGR). That’s an average cost of about $21,000 per well, not accounting for inflation. From 2002-2018, DOGGR plugged about 600 wells at a cost of $18.6 million; an average cost of about $31,000.

Where are they?

The map above shows the locations of idle wells in California.  There are 29,515 wells listed as idle and 122,467 plugged or buried wells as of the most recent DOGGR data, downloaded 3/20/19. There are a total of 245,116 oil and gas wells in the state, including active, idle, new (permitted) or plugged.

Of the over 29,000 wells are listed as idle, only 3,088 (10.4%) reported production in 2018. Operators recovered 338,201 barrels of oil and 178,871 cubic feet of gas from them in 2018. Operators injected 1,550,436,085 gallons of water/steam into idle injection wells in 2018, and 137,908,884 cubic feet of gas.

The tables below (Tables 1-3) provide the rankings for idle well counts by operator, oil field, and county (respectively).  Chevron, Aera, Shell, and California Resources Corporation have the most idle wells. The majority of the Chevron idle wells are located in the Midway Sunset Field. Well over half of all idle wells are located in Kern County.

Risks

According to the Western States Petroleum Association (WSPA) the count of idle wells in California has increased from just over 20,000 idle wells in 2015 to nearly 30,000 wells in 2018! That’s an increase of nearly 50% in just 3 years!

Nobody knows how many orphaned wells are actually out there, beneath homes, in forests, or in the fields of farmers. The U.S. EPA estimates that there are more than 1 million of them across the country, most of them undocumented. In California, DOGGR officially reports that there are 885 orphaned wells in the state.

A U.S. EPA report on idle wells published in 2011 warned that existing monitoring requirements of idle wells in California was “not consistent with adequate protection” of underground sources of drinking water. Idle wells may have leaks and damage that go unnoticed for years, according to an assessment by the state Department of Conservation (DOC). The California Council on Science and Technology is actively researching this and many other issues associated with idle and orphaned wells. The published report will include policy recommendations considering the determined risks. The report will determine the following:

  • State liability for the plugging and abandoning of deserted and orphaned wells and decommissioning facilities attendant to such wells
  • Assessment of costs associated with plugging and abandoning deserted and orphaned wells and decommissioning facilities attendant to such wells
  • Exploration of mechanisms to ameliorate plugging, abandoning, and decommissioning burdens on the state, including examples from other regions and questions for policy makers to consider based on state policies

Current regulation

As of 2018, new CA legislation is in effect to incentivize operators to properly plug and abandon their stocks of idle wells. In California, idle wells are defined as wells that have not had a 6-month continuous period of production over a 2-year period (previously a 5-year period). The new regulations require operators to pay idle well fees.  The fees also contribute towards the plugging and proper abandonment of California’s existing stock of orphaned wells. The new fees are meant to act as bonds to cover the cost of plugging wells, but the fees are far too low:

  • $150 for each well that has been idle for 3 years or longer, but less than 8 years
  • $300 for each well that has been idle for 8 years or longer, but less than 15 years
  • $750 for each well that has been idle for 15 years or longer, but less than 20 years
  • $1,500 for each well that has been idle for 20 years or longer

Operators are also allowed to forego idle well fees if they institute long-term idle well management and elimination plans. These management plans require operators to plug a certain number of idle wells each year.

In February 2019, State Assembly member Chris Holden introduced an idle oil well emissions reporting bill. Assembly bill 1328 requires operators to monitor idle and abandoned wells for leaks. Operators are also required to report hydrocarbon emission leaks discovered during the well plugging process. The collected results will then be reported publicly by the CA Department of Conservation. According to Holden, “Assembly Bill 1328 will help solve a critical knowledge gap associated with aging oil and gas infrastructure in California.”

While the majority of idle wells are located in Kern County, many are also located in California’s South Coast region. Due to the long history and high density of wells in the Los Angeles, the city has additional regulations. City rules indicate that oil wells left idle for over one year must be shut down or reactivated within a month after the city fire chief tells them to do so.

Who is responsible?

All of California’s wells, from Kern County to three miles offshore, on private and public lands, are managed by DOGGR, a division of the state’s Department of Conservation. Responsibilities include establishing and enforcing the requirements and procedures for permitting wells, managing drilling and production, and at the end of a well’s lifecycle, plugging and “abandoning” it.

To help ensure operator liability for the entire lifetime of a well, bonds or well fees are required in most states. In 2018, California updated the bonding requirements for newly permitted oil and gas wells. These fees are in addition to the aforementioned idle well fees. Operators have the option of paying a blanket bond or a bond amount per well. In 2018, these fees raised $4.3 million.

Individual well fees:

  • Wells less than 10,000 feet deep: $10,000
  • Wells more than 10,000 feet deep: $25,000

Blanket fees:

  • Less than 50 wells: $200,000
  • 50 to 500 wells: $400,000
  • 500 to 10,000 wells: $2,000,000
  • Over 10,000 wells: $3,000,000

With an average cost of at least $31,000 to plug a well, California’s new bonding requirements are still insufficient. Neither the updated individual nor blanket fees provide even half the cost required to plug a typical well.

Conclusions

Strategies for the managed decline of the fossil fuel industry are necessary to make the proposal a reality. Requiring the industry operators to shut down, plug and properly abandon wells is a step in the right direction, but California’s new bonding and idle well fees are far too low to cover the cost of orphan wells or to encourage the plugging of idle wells. Additionally, it must be stated that even properly abandoned wells have a legacy of causing groundwater contamination and leaking greenhouse gases such as methane and other toxic VOCs into the atmosphere.

Literally Millions of Failing, Abandoned Wells

By Kyle Ferrar, Western Program Coordinator, FracTracker Alliance

In California’s Central Valley and along the South Coast, there are many communities littered with abandoned oil and gas wells, buried underground.

Many have had homes, buildings, or public parks built over top of them. Some of them were never plugged, and many of those that were plugged have since failed and are leaking oil, natural gas, and toxic formation waters (water from the geologic layer being tapped for oil and gas). Yet this issue has been largely ignored. Oil and gas wells continue to be permitted without consideration for failing and failed plugged wells. When leaking wells are found, often nothing is done to fix the issue.

As a result, greenhouse gases escape into the atmosphere and present an explosion risk for homes built over top of them. Groundwater, including sources of drinking water, is known to be impacted by abandoned wells in California, yet resources are not being used to track groundwater contamination.

Abandoned wells: plugged and orphaned

The term “abandoned” typically refers to wells that have been taken out of production. At the end of their lifetime, wells may be properly abandoned by operators such as Chevron and Shell or they may be orphaned.

When operators properly abandon wells, they plug them with cement to prevent oil, natural gas, and salty, toxic formation brine from escaping the geological formation that was tapped for production. Properly plugging a well helps prevent groundwater contamination and further air quality degradation from the well. The well-site at the surface may also be regraded to an ecological environment similar to its original state.

Wells that are improperly abandoned are either plugged incorrectly or are “orphaned” by their operators. When wells are orphaned, the financial liability for plugging the well and the environmental cleanup falls on the state, and therefore, the taxpayers.

You don’t see them?

In California’s Central Valley and South Coast abandoned wells are everywhere. Below churches, schools, homes, they even under the sidewalks in downtown Los Angeles!

FracTracker Alliance and Earthworks recently spent time in Los Angeles with an infrared camera that shows methane and volatile organic compound (VOC) emissions. We visited several active neighborhood drilling sites and filmed plumes of toxic and carcinogenic VOCs floating over the walls of well-pads and into the surrounding neighborhoods. We also visited sites where abandoned, plugged wells had failed.

In the video below, we are standing on Wilshire Blvd in LA’s Miracle Mile District. An undocumented abandoned well under the sidewalk leaks toxic and carcinogenic VOCs through the cracks in the pavement as mothers push their children in walkers through the plume. This is just one case of many that the state is not able to address.

California regulatory data shows that there are 122,466 plugged wells in the state, as shown below in the map below. Determining how many of them are orphaned or improperly plugged is difficult, but we can come up with an estimate based on the wells’ ages.

While there are no available data on the dates that wells were plugged, there are data on “spud dates,” the date when operators begin drilling into the ground. Of the 18,000 wells listing spud dates, about 70% were drilled prior to 1980. Wells drilled before 1980 have a higher risk of well casing failures and are more likely to be sources of groundwater contamination.

Additionally, wells plugged prior to 1953 are not considered effective, even by industry standards. Prior to 1950, wells either were orphaned or plugged and abandoned with very little cement. Plugging was focused on protecting the oil reservoirs from rain infiltration rather than to “confine oil, gas and water in the strata in which they are found and prevent them from escaping into other strata.” Of the wells with drilling dates in the regulatory data, 30% are listed as having been drilled prior to the use of cement in well plugging.

With a total of over 245,000 wells in the state database, and considering the lack of monitoring prior to 1950, it’s reasonable to assume there are over 80,000 improperly plugged and unplugged wells in California.

The issue is not unique to California. Nationally, an estimated 2.56 million oil and gas wells have been drilled and 1.93 million wells had been abandoned by 1975. Using interpolated data, the EPA estimates that as of 2016 there were 3.12 million abandoned wells in the U.S. and 69% of them were left unplugged.

In 2017, FracTracker Alliance organized an exercise to track down the locations of Pennsylvania’s abandoned wells that are not included in the PA Department of Environmental Protection’s digital records. Using paper maps and the FracTracker Mobile App, volunteers explored Pennsylvania woodlands in search of these hidden greenhouse gas emitters.

What are the risks?

Emissions

Studies by Kang et al. 2014, Kang et al 2016, Boothroyd et al 2016, and Townsend-Small et al. 2016 have all measured methane emissions from abandoned wells. Both properly plugged and improperly abandoned wells have been shown to leak methane and other VOCs to the atmosphere as well as into the surrounding groundwater, soil, and surface waters. Leaks were shown to begin just 10 years after operators plugged the wells.

Well density

The high density of aging and improperly plugged wells is a major risk factor for the current and future development of California’s oil and gas fields. When fields with old wells are reworked using new technology, such as hydraulic fracturing, CO2 flooding, or solvent flooding (including acidizing, water flooding, or steam flooding), the injection of additional fluid and gas increases pressure in a reservoir. Poorly plugged or aging wells often lack the integrity to avoid a blowout (the uncontrolled release of oil and/or gas from a well). There is a consistent risk that formation fluids will be forced to migrate up the plugged wellbores and bypass the existing plugs.

Groundwater

In a 2014 report, the U.S. Geological Service warned the California State Water Resources Control Board that the integrity of abandoned wells is a serious threat to groundwater sources, stating, “Even a small percentage of compromised well bores could correspond to a large number of transport pathways.”

The California Council on Science and Technology (CCST) has also suggested the need for additional research on existing aquifer contamination. In 2014, they called for widespread testing of groundwater near oil and gas fields, which has still not occurred.

Leaks

In addition to the contamination of underground sources of drinking water, abandoned well failures can even create a pathway for methane and fluids to escape to Earth’s surface. In many cases, such as in Pennsylvania, Texas, and California, where drilling began prior to the turn of the 20th century, many wells have been left unplugged. Of the abandoned wells that were plugged, the plugging process was much less adequate than it is today.

If plugged wells are allowed to leak, surface expressions can form. These leaks can travel to the Earth’s crust where oil, gas, and formation waters saturate the topsoil. A construction supervisor for Chevron named David Taylor was killed by such an event in the Midway-Sunset oil field near Bakersfield, CA. According to the LA Times, Chevron had been trying to control the pressure at the well-site. The company had stopped injections near the well, but neighboring operators continued high-pressure injections into the pool. As a result, migration pathways along old wells allowed formation fluids to saturate the Earth just under the well-site. Tragically, Taylor fell into a 10-foot diameter crater of 190° fluid and hydrogen sulfide.

California regulations

Following David Taylor’s death in 2011, California regulators vowed to make urgent reforms to the management of underground injection, and new rules finally went into effect on April 1, 2018. These regulations require more consistent monitoring of pressure and set maximum pressure standards. While this will help with the management of enhanced oil recovery operations, such as steam and water flooding and wastewater disposal, the issue of abandoned wells is not being addressed.

New requirements incentivizing operators to plug and abandon idle wells will help to reduce the number of orphan wells left to the state, but nothing has been done or is proposed to manage the risk of existing orphaned wells.

Conclusion

Why would the state of California allow new oil and gas drilling when the industry refuses to address the existing messes? Why are these messes the responsibility of private landholders and the state when operators declare bankruptcy?

New bonding rules in some states have incentivized larger operators to plug their own wells, but old low-producing or idle wells are often sold off to smaller operators or shell (not Shell) companies prior to plugging. This practice has been the main source of orphaned wells. And regardless of whether wells are plugged or not, research shows that even plugged wells release fugitive emissions that increase with the age of the plug.

If the fossil fuel industry were to plug the existing 1.666 million currently active wells, there would be nearly 5 million plugged wells that require regular inspections, maintenance, and for the majority, re-plugging, to prevent the flow of greenhouse gases. This is already unattainable, and drilling more wells adds to this climate disaster.

destroyed home following pipeline explosion in San Bruno, CA

Unnatural Disasters

Guest blog by Meryl Compton, policy associate with Frontier Group

Roughly half of the homes in America use gas for providing heat, hot water or powering appliances. If you use gas in your home, you know that leaks are bad – they waste money, they pollute the air, and, if exposed to a spark, they could spell disaster.

Our homes, however, are only the end point of a vast production and transportation system that brings gas through a network of pipelines all the way from the wellhead to our kitchens. There are opportunities for wasteful and often dangerous leaks all along the way – leaks that threaten the public’s health and safety and contribute to climate change.

How frequent are gas leaks?

Between January 2010 and November 2018, there were a reported 1,888 incidents that involved a serious injury, fatality or major financial loss related to gas leaks in the production, transmission and distribution system, according to data from the Pipeline and Hazardous Materials Safety Administration. These incidents caused 86 deaths, 487 injuries and over $1 billion in costs.

When gas lines leak, rupture, or are otherwise damaged, the gas released can explode, sometimes right in our own backyards. Roughly one in seven of the incidents referenced above – 260 in total – involved an explosion.

In September 2018, for example, a series of explosions in three Massachusetts communities caused one death, numerous injuries and the destruction of as many as 80 homes. And there are many more stories like it from communities across the U.S. From the 2010 pipeline rupture and explosion in San Bruno, California, that killed eight people and destroyed almost 40 homes to the 2014 disaster in New York City that destroyed two five-story buildings and killed eight people, these events serve as a powerful reminder of the danger posed by gas.

The financial and environmental costs

Gas leaks are also a sheer waste of resources. While some gas is released deliberately in the gas production process, large amounts are released unintentionally due to malfunctioning equipment, corrosion and natural causes like flooding. The U.S. Energy Information Administration estimates that 123,692 million cubic feet of gas were lost in 2017 alone, enough to power over 1 million homes for an entire year. That amount is likely an underestimate. On top of the major leaks reported to the government agency in charge of pipeline safety, many of our cities’ aging gas systems are riddled with smaller leaks, making it tricky to quantify just how much gas is lost from leaks in our nation’s gas system.

Leaks also threaten the stability of our climate because they release large amounts of methane, the main component of gas and a potent greenhouse gas. Gas is not the “cleaner” alternative to coal that the industry often makes it out to be. The amount of methane released during production and distribution is enough to reduce or even negate its greenhouse gas advantage over coal. The total estimated methane emissions from U.S. gas systems have roughly the same global warming impact over a 20-year period as all the carbon dioxide emissions from U.S. coal plants in 2015 – and methane emissions are likely higher than this amount, which is self-reported by the industry.

In most states, there is no strong incentive for gas companies to reduce the amount of leaked gas because they can still charge customers for it through “purchased gas adjustment clauses.” These costs to consumers are far from trivial. Between 2001 and 2011, Americans paid at least $20 billion for gas that never made it to their homes.

These and other dangers of gas leaks are described in a recent fact sheet by U.S. PIRG Education Fund and Frontier Group. At a time when climate change is focusing attention on our energy system, it is critical that communities understand the full range of problems with gas – including the ever-present risk of leaks in the extensive network of infrastructure that brings gas from the well to our homes.

The alternative

We should not be using a fuel that endangers the public’s safety and threatens the stability of our climate. Luckily, we don’t have to. Switching to electric home heating and hot water systems and appliances powered by renewable energy would allow us to move toward eliminating carbon emissions from homes. Electric heat pumps are twice as efficient as gas systems in providing heat and hot water, making them a viable and commonsense replacement. Similarly, as the cost of wind and solar keep falling, they will continue to undercut gas prices in many regions.

It’s time to move beyond gas and create a cleaner, safer energy system.

California’s Oil Fields Add Fuel to the Fire

Never has the saying “adding fuel to the fire” been so literal.

California wildfires have been growing at unheard of rates over the last five years, causing record breaking destruction and loss of life. Now that we’ve had a little rain and perhaps a reprieve from this nightmare wildfire season, it is important to consider the factors influencing the risk and severity of fires across the state.

Oil and gas extraction and consumption are major contributors to climate change, the underlying factor in the recent frequent and intense wildfires. A lesser-known fact, however, is that many wildfires have actually burned in oil fields in California – a dangerous circumstance that also accelerates greenhouse gas emissions. Our analysis shows where this situation has occurred, as well as the oil fields most likely to be burned in the future.

First, we looked at where wildfires are currently burning across the state, shown below in Map 1. This map is from CAL FIRE and is continuously updated.

Map 1. The CAL FIRE 2018 Statewide Incidents Map

CAL FIRE map showing the locations and perimeters of California wildfires

California’s recent fire seasons

The two largest wildfires in California recorded history occurred last year. The Mendocino Complex Fire burned almost a half million acres (1,857 square kilometers) in Mendocino National Forest. The Thomas Fire in the southern California counties of Ventura and Santa Barbara burned nearly 282,000 acres (1,140 square kilometers). A brutal 2017 fire season, however is now overshadowed by the ravages of 2018’s fires.

With the effects of climate change increasing the severity of California’s multi-year drought, each fire season seems to get worse. The Woolsey Fire in Southern California caused a record amount of property damage in the hills of Santa Monica and Ventura County. The Camp Fire in the historical mining town of Paradise resulted in a death toll that, as of early December, has more than tripled any other wildfire. And many people are still missing.

The Thomas Fire

A most precarious situation erupts when a wildfire spreads to an oil field. Besides having a surplus of their super flammable namesake liquid, oil fields are also storage sites for various other hazardous and volatile chemicals. The Thomas Fire was such a scenario.

The Thomas fire burned through the steep foothills of the coastal Los Padres mountains into the oil fields. When in the oil fields, the oil pumped to the surface for production and the stores of flammable chemicals provided explosive fuel to the wildfire. While firefighters were able to get the majority of the fire “contained,” the oil fields were too dangerous to access. According to the community, oil fires remained burning for weeks before they were able to be extinguished.

The Ventura office of the Division of Oil Gas and Geothermal Resources (DOGGR) reported that the Thomas Fire burned through the Taylor Ranch oil fields and a half dozen other oil fields including the Ventura, San Miguelito, Rincon, Ojai, Timbe Canyon, Newhall-Portrero, Honor Rancho and Wayside Canyon. DOGGR Ventura officials said Newhall-Potrero was “half burned over.” Thomas also burned within a 1/3 mile of the Sespe oil field. Schools and other institutions closed down throughout the Los Angeles Basin, but DOGGR said there was no impact on oil and gas operations that far south. The fire spurred an evacuation of the Las Flores Canyon Exxon oil storage facility but thankfully was contained before reaching the facility.

Wildfire threat for oil fields

Map 2. California Wildfires in Oil Fields

The Thomas Fire was not the first time or the last time an oil field burned in a California wildfire. Map 2 above shows state wildfires from the last 20 years overlaid with maps of California oil fields, oil wells, and high threat wildfire zones. The map shows just the oil fields and oil and gas wells in California that have been burned by a wildfire.

We found that 160 of California’s 517 oil fields (31%) have been burned by encroaching wildfires, affecting more than 10,000 oil and gas well heads.

An ominous finding: the state’s highest threat zones for wildfires are located close to and within oil and gas fields.

The map shows that wildfire risk is greatest in Southern California in Ventura and Los Angeles counties due to the arid environment and high population density. Over half the oil fields that have burned in California are in this small region.

Who is at fault?

Reports show that climate change has become the greatest factor in creating the types of conditions conducive to uncontrollable wildfires in California. Climate scientists explain that climate change has altered the natural path of the Pacific jet stream, the high-altitude winds that bring precipitation from the South Pacific to North America.

In a recent study, researchers from the University of Idaho and Columbia University found that the impact of global warming is growing exponentially. Their analysis shows that since 2000, human-caused climate change prompted 75% more aridity — causing peak fire season to expand every year by an average of nine days. The Fourth National Climate Assessment details the relationship between climate change and wildfire prevalence, and comes to the same conclusion: impacts are increasing.

On the cause of wildfires, the report explains:

Compound extremes can include simultaneous heat and drought such as during the 2011–2017 California drought, when 2014, 2015, and 2016 were also the warmest years on record for the state; conditions conducive to the very large wildfires, that have already increased in frequency across the western United States and Alaska since the 1980s.

Both 2017 and 2018 have continued the trend of warmest years on record, and so California’s drought has only gotten worse. The report goes on to discuss the threat climate change poses to the degradation of utilities’ infrastructure. Stress from climate change-induced heat and drought will require more resources dedicated to maintaining utility infrastructure.

The role of public utilities

The timing of this report could not be more ironic considering the role that utilities have played in starting wildfires in California. Incidents such as transformer explosions and the degradation of power line infrastructure have been implicated as the causes of multiple recent wildfires, including the Thomas Fire and the most recent Woolsey and Camp wildfires – three of the most devastating wildfires in state history. As public traded corporations, these utilities have investors that profit from their contribution to climate change which, in turn, has created the current conditions that allow these massive wildfires to spread. On the other hand, utilities in California may be the least reliant on fossil fuels. Southern California Edison allows customers to pay a surcharge for 100% renewable service, and Pacific Gas and Electric sources just 20% of their electricity from natural gas.

As a result of the fire cases, each of which might be attributed to negligence, stock prices for the two utilities plummeted but eventually rebounded after the California Public Utilities Commission (CPUC) assured investors that the utilities would be “bailed out” in the case of a possible financial failure to the reproach of the general public. The CPUC assured that the state could bail out utilities if they were forced to finance recovery for the fires they may have caused.

CPUC President, Michael Picker, stated:

The CPUC is one of the government agencies tasked with ensuring that investor-owned utilities operate a safe and reliable grid… An essential component of providing safe electrical service is the financial wherewithal to carry out safety measures.

Along with regulation and oversight, part of the agency’s work involves ensuring utilities are financially solvent enough to carry out safety measures.

Conclusion

January 1, 2019 will mark the seventh year of drought in California. Each fall brings anxiety and dread for state residents, particularly those that live in the driest, most arid forests and chaparral zones. Data show that the wildfires continue to increase in terms of intensity and frequency as the state goes deeper into drought induced by climate change.

While California firefighters have been incredibly resourceful, over 70% of California forest land is managed by the federal government whose 2019 USDA Forest Service budget reduces overall funding for the National Forest System by more than $170 million. Moving forward, more resources must be invested in supporting the health of forests to prevent fires with an ecological approach, rather than the current strategy which has focused predominantly on the unsustainable practice of fuel reduction and the risky tactics of “fire borrowing”. And of course, the most important piece of the puzzle will be addressing climate change.

Map of offshore drilling in California

The Feds Trump California’s State Ban on Offshore Oil Drilling

Offshore drilling in the United States federal waters has caused the most environmentally destructive disasters in North America. Yet, new policy is pushing for the expansion of offshore drilling, particularly off the coast of California.

Offshore Drilling History

In 1969, Union Oil’s offshore rig Platform A had a blowout that leaked 100,000 barrels into the Santa Barbara Channel, one of the most biologically diverse marine environments in the world. The spill lasted ten days and killed an estimated 3,500 sea birds, as well as an untold number of marine mammals. Unbelievably, the Santa Barbara spill is only the third largest spill in U.S. waters. It follows the 1989 Exxon Valdez and the 2010 Deepwater Horizon spills. These incidents keep getting bigger.

More offshore drilling means a higher risk of catastrophe, additional contamination of air and water locally, and more greenhouse gas emissions globally.

Federal Moratorium on California Offshore Leases

Up until the beginning of 2018, further oil and gas development using offshore oil rig platforms seemed quite unlikely. After the 1969 oil spill from Platform A and the subsequent ban on further leasing in state waters, the risk of another devastating oil spill was too large for even the federal government to consider new leases. The fact that the moratorium lasted through 16 years of Bush presidencies is truly a victory. Across the aisle, expanding offshore operations has been opposed. In Florida, even Republican Governor Rick Scott teamed up with environmental groups to fight the Department of Interior’s recent sales of offshore leases.

Trump’s New Gas Leasing Program

Now, the U.S. Bureau of Ocean Energy Management (BOEM) is preparing a new 2019-2024 national Outer Continental Shelf (OCS) oil and gas leasing program to replace the existing 2017-2022 program. This is an unusual practice, and part of Trump’s America-First Offshore Energy Strategy. The Trump administration opened up most of the US coastal waters for new oil and gas drilling with a recent draft proposal offering 47 new offshore block lease sales to take place between 2019 and 2024.

Where might these new leases occur?

The offshore federal waters that are open for oil and gas leases are shown in dark blue in the map below (Figure 1). Zoom out to see the extent.

California’s Offshore Oil

Southern California has a legacy of oil extraction, particularly Los Angeles. It’s not just the federal government that is keen on continuing this legacy. While the state has not permitted the leasing of new blocks in offshore waters, Governor Brown’s policies have been very friendly to the oil and gas industry. According to Oil Change International’s Sky’s the Limit report: “Under the Brown administration, the state has permitted the drilling of more than 20,000 new wells,” including 5,000 offshore wells in state waters. About 2,000 of these offshore wells have been drilled since 2012.

This map developed in collaboration with Consumer Watch Dog juxtaposes the offshore wells drilled in CA state waters with those drilled in federal waters.

Southern California is the main target for future offshore leasing. The Monterey Shale formation, which underlies the city of Los Angeles and expands north offshore to the Ventura Coast, is thought to contain the largest conventional oil plays left IN THE WORLD! The map above shows the locations of state and federal offshore oil and gas wells and the rigs that service them. It also shows historical wells off the coast of Northern California.

Northern California, both onshore and offshore, sits on top of major reserves of natural gas, which may also be developed given the political climate. With an increase in the price of natural gas, operators will be developing these gas fields. Some operators, such as Chevron, have already drilled natural gas wells in northern California, but have left the wells “shut in” (capped) until production becomes more profitable.

For a more comprehensive coverage on environmental impacts of offshore operations, including those to sensitive species, check out the Environmental Defense Center’s Dirty Water Report and read our additional coverage of California’s existing offshore drilling, and offshore fracking.

Air Pollution from Oil Rigs

FracTracker, in collaboration with Earthworks, recently teamed up with the Center for Biological Diversity and Greenpeace International to get up close to offshore oil rigs. As a certified Optical Gas Imaging Thermographer, Kyle Ferrar (Western Program Coordinator for FracTracker Alliance and California Community Empowerment Project Organizer for Earthworks), took footage of the offshore oil rigs.

Using infrared technology, we were able to visualize and record emissions and leaks of volatile hydrocarbons and other greenhouse gases coming from these offshore sites. We documented many cases of intense flaring from the rigs, including several cases where the poorly burning flare allowed hydrocarbons to be leaked to the atmosphere prior to complete combustion of CO2.

More complete coverage of this trip can be found here on the Greenpeace website.

Below you can view a compilation of the footage we were able to capture from small pontoon boats.

Conclusion

FracTracker has looked at offshore oil and gas drilling from many different angles. We have looked to the past, and found the most egregious environmental damages in U.S. history. We have analyzed the data and shown where, when, and how much offshore drilling is happening in California. We have demonstrated that much of the drilling and many of the proposed leases are in protected and sensitive habitats. We have looked at policy and found that both Governor Brown and President Trump are aligned to promote more oil and gas development. We have even looked at the rigs in person in multiple spectrums of light and found that these operations continuously leak and emit greenhouse gases and other air toxins.

No matter which way you look at offshore oil and gas drilling, it is clearly one of the most threatening methods of oil and gas extraction in use today.

Governor Brown’s Climate Summit Heats up Political Climate

Overview

California has become a battleground for real climate action. The state Governor, Jerry Brown prides himself in his own climate leadership, and California has pushed EU nations and countries worldwide to take climate change seriously. As a final tribute to his own tenure as a term-limited governor, Brown has organized and hosted a Global Climate Action Summit, September 12-14th. The summit convenes an international invitation list of “climate leaders” to, in their words:

“Take Ambition to the Next Level.” It will be a moment to celebrate the extraordinary achievements of states, regions, cities, companies, investors and citizens with respect to climate action. It will also be a launchpad for deeper worldwide commitments and accelerated action from countries—supported by all sectors of society—that can put the globe on track to prevent dangerous climate change and realize the historic Paris Agreement.

Meanwhile, frontline communities, community organizers, and grassroots organizations contest the perspective that real change has been made. While investors and green capitalists celebrate, frontline communities fight daily for clean air and water. In solidarity with and led by frontline communities, activists have protested the summit, in an attempt to hold policy makers accountable to those most affected by the fossil fuel industry.

Rise for Climate, Jobs, and Justice

One quarter of a million people worldwide, and well over 30,000 in San Francisco hit the streets during the Rise for Climate last Saturday, September 8th. With over 900 actions taking place simultaneously people worldwide demanded real climate action from their local leaders. FracTracker Alliance staff helped coordinate and participated in events nationwide.

In San Francisco, the march was led by members of the Indigenous community, making up the Indigenous Bloc, on the frontlines of the action. The day officially started with prayers from Indigenous leaders and a moment of silence for Indigenous Peoples that have been most harmed by the effects of climate change. Dozens of various other movements followed the Indigenous Bloc in a parade of support. FracTracker took the opportunity to document this monumental event, and photos from the march are shown below.

March Photos

For California and international “climate leaders” in attendance, Rise kicked off a long week of climate action culminating with the Global Action Climate Summit. The week is full of activities geared towards movement building, including the Solidarity to Solutions Summit (#sol2sol) by It Takes Roots; Women’s Assembly for Climate Justice, hosted by Women’s Earth and Climate Action Network; and mass actions including a march and occupation of the Global Climate Action Summit!

SB100

To mark such a momentous movement, the Brown administration signed a new bill into law, SB100. The new law, authored by Kevin De León (D-Los Angeles), pledges that all of California’s electricity will come from clean power sources by 2045. Brown said, “California is committed to doing whatever is necessary to meet the existential threat of climate change.” This is the most ambitious state climate policy in the U.S. The legislation barely passed the state Legislature after nearly two years of debate, with opponents arguing that it would lead to higher electric bills for all Californians.

Opposition from Eco-Activists

In opposition to the feel-good, pat-yourself-on-the-back feelings from delegates at the summit, frontline communities and activists respond that the SB100 legislation does nothing to stop harms to frontline communities caused by extraction and the supply side of the fossil fuel economy. The Against Climate Capitalism campaign is a coalition of Diablo Rising Tide teamed up with Idle No More SF Bay, the Ruckus Society, It Takes Roots, Indigenous Environmental Network and the Brown’s Last Chance. Members of the coalition have been outspoken proponents organizing in support of real climate leadership. The coalition is pushing for Governor Jerry Brown and the California legislature to end the extraction of new fossil fuels in California. The green groups making up these larger coalition networks encompass a broad range research and advocacy groups, from international groups like Greenpeace to local grassroots movements from Los Angeles and California’s Central Valley. FracTracker Alliance is also a campaign member.

The goal of the campaign is to keep fossil fuels in the ground, and supports a just transition from a fossil fuel economy to clean energy sources. A petition to pressure California Governor Jerry Brown to end fossil fuel extraction can be found on their website. The California legislature and the Brown administration has consistently failed to address the impacts of extraction in its own backyard. While frontline communities are suffering, the Brown administration continues to take the easy way out with future legislation such as SB100, which does nothing to address the environmental justice spector of actual oil drilling and production. In response to SB100, the campaign has issued response:

  • Governor Brown has consistently failed to address the supply side of oil and the drilling in California, which is an indispensable step to avoid the worst effects of climate destruction.
  • Some 5.4 million Californians live within a mile of at least one oil or gas well, and this includes hundreds of thousands of children. Many suffer illnesses from toxic exposure and cannot wait for action.
  • Brown’s failure to act on this issue is a massive moral failure from which no bill signing can distract. Despite his signing of an important and historical bill he did nothing to draft or support, Governor Brown can expect to be greeted with energetic and committed protest at the Global Climate Action summit this week.

With these poignant criticisms, it begs the question; how can Governor Jerry Brown continue to ignore the actual cause of climate change? Brown has passed legislation ensuring that everyday Californians will bear the costs for clean energy utilities, but has done nothing to hold accountable the actual culprits responsible for climate change, the oil and gas corporations extracting the 5.7 million barrels of oil per year from California soil.

Leaking tank in Arvin

Arvin, CA Setback Ordinance Passes Unanimously!

The small city of Arvin, CA has succeeded in taking a brave step forward to protect the public health of its community.

On July 17, 2018 the Arvin City Council voted 3-0 (two members were absent) in support of a setback ordinance. This is the first California oil and gas ordinance that has an actual effect, as it is the first in a region where drilling and fracking are actively occurring. The Arvin, CA setback ordinance prevents wells from being drilled in residential or commercially-zoned spaces. Also, setback distances of 300 feet for new development and 600 feet for new drilling operations have been established for sensitive sites, such as parks, hospitals, and schools.

(To see where other local actions have been taken in California, check out our coverage of local actions and map, which was recently updated.)

More details and maps of the setback ordinance and its development can be found in the initial FracTracker coverage of the proposal, below:

The measure was supported by Arvin Mayor Jose Gurrola. He described the front-lines experience of Arvin citizens:

The road to the update has been difficult for this community. Eight Arvin families were evacuated after a toxic gas leak from an underground oilfield production pipeline located near their homes in 2014. Some have now been re-occupied by concerned residents with no other options; other homes still stand empty. Meanwhile, a short distance away an older pump jack labors day and night next to homes pumping oil mixed with water to a nearby tank. Despite multiple complaints to state agencies of odors and noise by the residents, they are told by the agencies that there is nothing that can be done under the current regulations. The pump jack continues to creak along as children walk nearby on their way to school, covering their faces as the smell occasionally drifts their direction. – Jose Gurrola, Mayor of the City of Arvin

Fugitive Emissions Monitoring

In anticipation of the city council’s vote, FracTracker collaborated with Earthworks and the grassroots organization Central California Environmental Justice Network to visit the urban well sites within the city limits. Using Infrared FLIR technology, the sites were assessed for fugitive emissions and leaks. Visualizing emissions of volatile organic compounds (VOCs) at these sites provides a glimpse to what the community living near these wells are continually exposed. The infrared cameras used in these videos are calibrated to the wavelengths of the infrared spectrum where VOC hydrocarbons of interest are visible.

The map below shows the locations that were visited, as indicated by the three stars. Videos of each site are shown below the map.

FLIR Videos and Findings

Sun Mountain Simpson-1 Lease

In this FLIR video of Sun Mountain Simpson-1, fugitive emissions are obvious. The emissions are coming from the PV vent at the top of the produced water tank. These emissions are a mixture of a variety of volatile organic compounds, such as BTEX compounds and methane. This well site is located between homes, a small apartment complex, and a playground. While on the ground operating the FLIR camera I felt light headed, dizzy, and developed a headache. The emissions were reported to the San Joaquin Valley Air District (SJVAD), who sampled and found VOC concentrations at dangerous levels. The well operator was notified but refused to respond. Unfortunately, because this particular well produces under 50 barrels of oil/day, the site is exempt from any health related emissions regulations.

Sun Mountain Jewett 1-23 Lease

This well site is located near a number of single family homes and next two a park. The well site is also on the future location of the Arvin Community College. The FLIR video below is particularly interesting because it shows fugitive emissions from four different locations. The leaks include one at the well head that is potentially underground, one on separator equipment, and leaks from each of the tank PV hatches. When regulators were notified, they visited the site and fixed two of the leaks immediately. Fugitive emissions from the PV hatches were not addressed because this site is also exempt from regulations.

ABA Energy Corporation Richards Facility Tank Farm

The Richards Facility Tank Farm is a well site located outside the city limits on farmland. The facility is regulated as a point source of air pollution, therefore enforcement action can require the operator to fix leaks even from PV hatches on tanks. This FLIR video shows leaks from PV hatches, and a major leak from a broken regulator valve. A complaint was submitted to the SJVAD, and the operator was required to replace the broken regulator valve.

Can Californians Escape Oil and Gas Pollution?

The city of Los Angeles is considering a 2,500-foot setback safety buffer between residences and oil and gas wells. Support for the proposal is being led by the grassroots group Stand Together Against Neighborhood Drilling (STAND-LA). The push for a setback follows a recent report by the Los Angeles County Department of Public Health. According to Stand LA:

The report, requested by both the Los Angeles County Supervisors and the Los Angeles City Council, outlines the health impacts faced by residents living, attending school or worshiping near one of Los Angeles County’s 3,468 active oil wells, 880 of which operate in the City of Los Angeles.

The Department outlines the clear health impacts on residents living near active oil wells, including: adverse birth outcomes, increased cancer risk, eye, nose and throat irritation, exacerbation of asthma and other respiratory illnesses, neurological effects such as headaches and dizziness, gastrointestinal effects such as nausea and abdominal pain, and mental health impacts such as depression, anxiety or fatigue.

This information is, of course, nothing new. Living near oil and gas extraction activities, and specifically actively producing wells, has been shown in the literature to increase risks of various health impacts – including asthma and other respiratory diseases, cardiovascular disease, cancer, birth defects, nervous disorders and dermal irritation, among others.1

Spatial Assessment

While Los Angeles would benefit the most from any type of setback regulation due to the county and city’s high population density, the rest of the state would also benefit from the same.

We conducted an assessment of the number of California citizens living proximal to active oil and gas production wells to see who all would be affected by such a change. Population counts were estimated for individuals living within 2,500 feet of an oil and gas production well for the entire state. An interactive map of the wells that fall within 2,500 feet of a residence in California is shown just below in Figure 1.

Figure 1. California 2,500’ oil and gas well buffer, above. The map shows a 2,500’ buffer around active oil and gas wells in California. Wells that are located within 1,000’; 1,500’; and 2,500’ from a residence, hospital or school are also shown in the map. The counts of individuals located within 2,500’ of an active well are displayed for census tracts.

Population Statistics

The number and percentage of California residents living within 2,500 feet of an active (producing) oil and gas well are listed below:

  • Total At-Risk Population

    859,699 individuals in California live within 2,500 feet of an active oil and gas well

  • % Non-White

    Of the total, 385,067 are “Non-white” (45%)

  • % Hispanic

    Of the total, 341,231 are “Hispanic” (40%) as defined by the U.S. Census Bureau2

We calculated population counts within the setbacks for smaller census-designated areas, including counties and census tracts. The results of the calculations are presented in Table 1 below.

Table 1. Population Counts by County

County Total Pop. Impacted Pop. Impacted % Non-White Impacted % Hispanic
Los Angeles 9,818,605 541,818 0.54 0.46
Orange 3,010,232 202,450 0.25 0.19
Kern 839,631 71,506 0.34 0.43
Santa Barbara 423,895 8,821 0.44 0.71

Contra Costa 1,049,025 1,174 0.35 0.30

Table 1 presents the counts of individuals living within 2,500 feet of an active oil and gas well, aggregated by county. Only the top 12 counties with the highest population counts are shown. “Impacted Population” is the count of individuals estimated to live within 2,500 feet of an oil and gas well. The “% Non-white” and “% Hispanic” columns report the estimated percentage of the impacted population of said demographic. There may be some overlap in these categories.

Conclusions

California is unique in many ways, beautiful beaches and oceans, steep mountains, massive forests, but not least of all is the intensity of the oil and gas industry. Not only are some of the largest volumes of oil extracted from this state, but extraction occurs incredibly close to homes, sometimes within communities – as shown in the photo at the top of this post.

The majority of California citizens living near active production wells are located in Los Angeles County – well over half a million people. LA County makes up 61% of Californians living within 2,500 feet of an oil and gas well, and half of them are non-white minority, people of color.

Additionally, the well sample population used in this analysis is limited to only active production wells. Much more of California’s population is exposed to pollutants from the oil and gas support activities and wells. These pollutants include acidic vapors, hydrocarbons, and diesel particulate matter from exhaust.

Our numbers are, therefore, a conservative estimate of just those living near extraction wells. Including the other activities would increase both the total numbers and the demographic percentages because of the high population density in Los Angeles.

For many communities in California, therefore, it is essentially impossible for residents to escape oil and gas pollution.


The Analysis – How it was done!

Since the focus of this assessment was the potential for impacts to public health, the analysis was limited to oil and gas wells identified as active – meaning they are producing or are viable to produce oil and/or natural gas. This limitation on the dataset was justified to remain conservative to the most viable modes of exposure to contaminants from well sites. Under the assumption that “plugged,” “buried,” or “idle” wells that are not producing (or at least reporting production figures to DOGGR) do not purvey as much as a risk of air emissions, the main route of transport for pollutants to the surrounding communities is via air emissions from “producing” oil and gas wells. The status of wells was taken from DOGGR’s “AllWells.zip” dataset (downloaded 3/7/18).

Analysis Steps:

  1. The first step was to identify oil and gas wells in California affected by 2,500’ and shorter setbacks from occupied dwellings. To achieve this, the footprints of occupied dwellings were identified, and where there was not a data source available the footprints were digitized.
  2. Using GIS tools, 2,500’ buffers were generated from the boundary of the occupied dwellings and a subset of active oil and gas wells located within the buffer zone were generated.
  3. A combination of county and city zoning data and county parcel data was used to direct the selection of building footprint GIS data and the generation of additional building footprint data. Building footprint data is readily available for a number of California cities, but was not available for rural areas.
  4. Existing footprint data was vetted using zoning codes.
  5. Areas located within 2,500’ of well-heads were prioritized for screening satellite imagery in areas zoned for residential use.

Analytical Considerations

Buildings and facilities housing vulnerable populations were also included. Vulnerable populations include people such as children, the elderly, and the immunocompromised. These areas pose an elevated risk for such sensitive populations when they live near hazardous sites, such as oil fields in LA. A variety of these types of sites were included in the GIS analysis, including schools and healthcare facilities.

GIS techniques were used to buffer active oil and gas wells at 2,500 feet. GIS shapefiles and 2010 Decennial census data was downloaded from American Fact Finder via Census.gov for the entire state of California at the census block level.2 Census block GIS layers were clipped to the 2,500-foot buffers. Population data found in Summary File 1 for the 2010 census was attached to the clipped census block GIS layers.  Adjusted population counts were calculated according to the proportion of the area of the census block falling within the 2,500’ buffer.

California regulators need to protect groundwater from oil and gas waste this time around

By Kyle Ferrar, Western Program Coordinator, FracTracker Alliance

California’s 2nd Largest Waste Stream

Every year the oil and gas industry in California generates billions of gallons of wastewater, also known as produced water. According to a study by the California Council on Science and Technology, in 2013, more than 3 billion barrels of produced water were extracted along with some 0.2 billion barrels of oil across the state. This wastewater is usually contaminated with a mixture of heavy metals, hydrocarbons, naturally occurring radioactive materials, and high levels of salts. Yet, contaminated wastewater from oil-field operations is exempt from the hazardous waste regulations enforced by the Resource Conservation and Recovery Act (RCRA).

Operators are, therefore, not required to measure or report the chemistry of this wastewater. Even with these unknowns, it is legally re-injected back into groundwater aquifers for disposal. Once an aquifer is contaminated it can be extremely difficult, if not impossible, to clean up again. Particularly in California, where water resources are already stretched thin, underground injection of oil and gas wastewater is a major environmental and economic concern.

Regulatory Deficiency

Under the Underground Injection Control program, wastewater is supposed to be injected only into geologic formations that don’t contain usable groundwater. However, a loophole in the Safe Drinking Water Act allows oil and gas companies to apply for what’s called an aquifer exemption, which allows them to inject wastewater into aquifers that potentially hold high-quality drinking water. To learn more about aquifer exemptions, see FracTracker’s summary, here.

The California department responsible for managing these aquifer exemption permits – the Division of Oil, Gas, and Geothermal Resources (DOGGR) – has for decades failed in its regulatory capacity. In 2015, for example, DOGGR admitted that at least 2,553 wells had been permitted to inject oil and gas waste into non-exempt aquifers – aquifers that could be used for drinking water. Independent audits of DOGGR showed decades of poor record-keeping, lax oversight, and in some cases, outright defiance of the law – showing the cozy relationship between regulators and the oil and gas industry. While 176 wells (those that were injecting into the cleanest drinking water) were initially shut down, most of the rest of the 2,377 permits were allowed to continue injecting into disputed wells through the following two years of the regulatory process.

The injection wells targeted by the Environmental Protection Agency (EPA), including those that were shut down, are shown in the map below (Figure 1).

Figure 1. Map of EPA-targeted Class II Injection Wells

The timeline of all this is just as concerning. The State of California has known about these problems since 2011, when the EPA audited California’s underground injection program and identified substantial deficiencies in its program, including failure to protect some potential underground sources of drinking water, a one-size-fits-all geologic review, and inadequate and under-qualified staffing for carrying out inspections. In 2014, the Governor’s office requested that the California EPA perform an independent review of the program. EPA subsequently made a specific remediation plan and timeline for DOGGR, and in March of 2015 the State finalized a Corrective Action Plan, to be completed by February 2017.

Scientific Review of CA Oil and Gas Activities

Meanwhile, in 2013, the California Senate passed SB-4, which set a framework for regulating hydraulic fracturing in California. Part of the bill required an independent scientific study to be conducted on oil and gas well stimulation, including acid well stimulation and hydraulic fracturing. The California Council on Science and Technology organized and led the study, in collaboration with the Lawrence Berkeley National Laboratories, which combined original technical data analyses and a review of relevant literature, all of which was extensively peer-reviewed. The report argues that both direct and indirect impacts of fracking must be accounted for, and that major deficiencies and inconsistencies in data remained which made research difficult. They also recommended that DOGGR improve and modernize their record keeping to be more transparent.

Figure 2. Depths of groundwater total dissolved solids (a common measure of groundwater quality) in five oil fields in the Los Angeles Basin. Blue and aqua colors represent protected groundwater; the heavy black horizontal line indicates the shallowest hydraulically fractured well in each field. In three of the five wells (Inglewood, Whittier, and Wilmington), fracking and wastewater injection takes place directly adjacent to, or within, protected groundwater.

A major component of the SB-4 report covered California’s Class II injection program. Researchers analyzed the depths of groundwater aquifers protected by the Safe Drinking Water Act, and found that injection and hydraulic fracturing activity was occurring within the same or neighboring geological zones as protected drinking water (Figure 2*).

More Exemptions to be Granted

Now, EPA is re-granting exemptions again. Six aquifer exemptions have been granted, and more are on the docket to be considered. In this second time around, it is imperative that regulatory agencies be more diligent in their oversight of this permitting process to protect groundwater resources. At the same time, the 2015 California bill SB 83 mandates the appointment of an independent review panel to evaluate the Underground Injection Control Program and to make recommendations on how to improve the effectiveness of the program. This process is currently in the works and a panel has been assembled, and FracTracker Alliance will be working to provide data, maps and analyses for this panel.

Stay tuned for more to come on which aquifers are being exempted, why, and what steps are being taken to protect groundwater in California.
