EPA recently took action under the Toxic Substances and Control Act (TSCA) to ensure no TCE containing consumer products enter the marketplace before the Agency has the opportunity to evaluate the intended use and take appropriate action. The new rule issued April 6, 2016, known as a Significant New Use Rule (SNUR), requires any company intending to make certain TCE containing consumer products provide EPA 90-day notice before making the product.
The final rule applies to TCE manufactured (including import) or processed for use in any consumer product, except for use in cleaners and solvent degreasers, film cleaners, hoof polishes, lubricants, mirror edge sealants, and pepper spray. A consumer product is defined at 40 CFR 721.3 as “a chemical substance that is directly, or as part of a mixture, sold or made available to consumers for their use in or around a permanent or temporary household or residence, in or around a school, or in recreation.”
EPA’s June 2014 Work Plan Chemical Risk Assessment for TCE identified health risks associated with several TCE uses, including the arts and craft spray fixative use, aerosol and vapor degreasing, and as a spotting agent in dry cleaning facilities. In 2015, EPA worked with the only U.S. manufacturer of the TCE spray fixative product, PLZ Aeroscience Corporation of Addison, Illinois, resulting in an agreement to stop production of the TCE containing product and to reformulate the product with an alternate chemical.
It is important to note that this regulatory action may affect certain entities with pre-existing import certifications and export notifications required under TSCA.
The rule becomes effective 60 days from its publication in the Federal Register.

As required by the Hazardous Waste Electronic Establishment Act (Act), EPA’s efforts are ongoing to develop an e-manifest system. EPA issued its final rule in February 2014 (79 Fed. Reg. 7518, February 7, 2014) seeking to implement the Act’s requirement to create a national electronic manifest system and impose user fees as a means to fund its development and operation. Most recently, EPA has developed an e-manifest listserv to manage communications with the regulated community.
According to EPA, the listserv will: 1) provide stakeholders with program announcements and updates; and 2) facilitate e-manifest conversations among users and other stakeholders. There will be significant progress on the e-manifest program throughout 2016-2017, so participation in the listserv will be a good way to stay informed.
Interested parties may subscribe to EPA’s listserv at https://www3.epa.gov/epawaste/hazard/transportation/manifest/e-man.htm.
EPA conducted a webinar on developments with the e-manifest system in December 2015, and the presentation provides a good overview of the program and related schedule.
Along with the hazardous waste management changes for generators recently proposed by EPA, the e-manifest system will be another significant new development for thousands of companies regulated by RCRA and subject to hazardous waste manifest requirements.
EPA recently announced seven National Enforcement Initiatives (NEIs) for FY 2017-2019. Every three years, EPA identifies NEIs to focus resources on national environmental problems where there is significant non-compliance with laws, and where federal enforcement efforts can make a difference. According to EPA, the NEIs are selected with input from the public and other stakeholders across EPA’s state, local and tribal partners.
Starting October 1, 2016 and continuing for three fiscal years, the following are the NEIs:
- Reducing air pollution from the largest sources
- Cutting hazardous air pollutants*
- Ensuring energy extraction activities comply with environmental laws
- Reducing risks of accidental releases at industrial and chemical facilities*
- Keeping raw sewage and contaminated stormwater out of our nation’s waters
- Preventing animal waste from contaminating surface and groundwater
- Keeping industrial pollutants out of the nation’s waters*
*New for FY2017-2019 as of February 2016.
It is interesting to note that the newly identified NEIs appear to correspond to challenges that EPA recently confronted, including the Gold King Mine wastewater spill, the spill prevention litigation and settlement in New York, and the Flint, MI lead contaminated water matter, where recent government reports concluded EPA failed in its regulatory obligations to this community.
For more information, see EPA’s news release announcing these NEIs.
EPA has agreed to initiate rulemaking to better address industrial waste spills as part of a settlement with a coalition of environmental groups. The Environmental Justice Health Alliance for Chemical Policy Reform (EJHA), People Concerned About Chemical Safety (PCACS), and the Natural Resources Defense Council (NRDC), sued EPA last July alleging that the Agency had failed to prevent hazardous substance spills from industrial facilities, including above ground storage tanks. See Environmental Justice Health Alliance for Chemical Policy Reform et al. v. U.S. Environmental Protection Agency, et al., case number 1:15-cv-05705, in the U.S District Court for the Southern District of New York.

The webinar will provide insights on the technical aspects of chemical fingerprinting for a variety of contaminants, including PCBs, dioxins, and chlorinated solvents. The webinar will also provide an overview of how courts have treated chemical fingerprinting from an expert witness standpoint as well as a case study demonstrating how this technique can be used to delineate co-mingled plumes. Michael Bock, with Ramboll Environ will also be presenting at the webinar. Here is a link to the webinar brochure.
Yesterday evening, the Department of Health and Human Services designated Dr. Nicole Lurie, an agency assistant secretary, to lead the federal government’s response to the elevated lead levels allegedly found in the drinking water being provided by the City of Flint, Michigan, to its residents. This designation came on the heels of a meeting between Flint’s mayor and Valerie Jarrett in Washington, D.C. The federal government has elected to play a significant role in addressing this crisis, with President Obama signing an emergency declaration on Saturday which provided Flint with access to up to $5 million in federal funds. The crisis began in 2014 when Flint stopped getting water from Detroit and began obtaining its drinking water from the Flint River in an effort to lower costs.
The United States Environmental Protection Agency ("U.S. EPA") recently announced its 2015 enforcement statistics, noting that for fiscal year 2015, U.S. EPA initiated enforcement actions resulted in $404 million in penalties and fines. In addition, companies were required to invest more than $7 billion to control pollution and remediate contaminated sites; convictions for environmental crimes resulted in 129 years of combined incarceration for convicted defendants; and there was a total of $39 million committed to environmental mitigation projects that benefited communities throughout the United States.
The largest single penalty was the result of a Clean Air Act settlement with two automobile manufacturers that resulted in a $100 million penalty, forfeiture of emissions credits and more than $50 million being invested in pollution control and abatement measures. U.S. EPA's 2015 enforcement numbers were up from 2014 ($100 million in fines and penalties collected in 2014).

Here is some food for thought as we get ready to gobble down some turkey this Thanksgiving: A new $25 million plant under construction in North Carolina will convert turkey waste into energy. Prestage AgEnergy will use 55,000 tons of turkey litter a year to produce the equivalent of 95 million kilowatt hours of electricity and feed that renewable electricity back to the grid.
North Carolina has a lot of turkey waste on hand – it ranks second in the nation behind Minnesota in turkey production. In light of its prolific turkey farming, in 2007, the state passed an energy policy mandate that requires utilities to use a small amount of poultry waste-generated power. This will not be the first turkey-waste energy plant – Minnesota currently has a 55-megawat power plant designed to burn poultry waste as its primary fuel. However, the new North Carolina plant will reportedly be the first facility designed to run on 100-percent turkey waste.
Lynn Grayson and Steven Siros Publish Article on U.S. Legal and Regulatory Developments in Nanotechnology
Lynn Grayson and Steven Siros have published an article in the most recent issue of DRI’s Toxic Tort and Environmental Law Newsletter titled Nanotechnology: U.S. Legal and Regulatory Developments. In the article, Ms. Grayson and Mr. Siros discuss how nanotechnology affects every sector of the U.S. economy and impacts our lives in a myriad of ways through the 1,600 nanotechnology-based consumer goods and products we use on a daily basis. The article provides an overview of how nanotechnology is defined, insights on the regulatory framework and recent developments, possible concerns about nanomaterial use, and risk management considerations for U.S. businesses utilizing nanotechnology.
The full article is available here.
On September 15, 2015, US EPA’s Office of Enforcement and Compliance Assurance published a proposed list of national enforcement initiatives (NEIs) for fiscal years 2017–19. This latest NEI list includes NEIs from the last round (FY2014–16) as well as three new potential NEIs that US EPA is considering.
U.S. EPA Releases One-Week Internal Review on the Colorado Mine Blowout, Concludes the Incident Was “Inevitable”
Earlier this week, the U.S. EPA released its “Internal Review of the A
ugust 5, 2015 Gold King Mine Blowout,” which provides the EPA Internal Review Team’s “one week rapid assessment” of the events and potential factors contributing to the Colorado mine adit blowout earlier this month. The Review sets out a series of conclusions and recommendations, many of which lay the foundation for absolving the U.S. EPA of any wrongdoing here while proposing extensive recommendations for the future.
Cross-border pipelines have been the subject of much controversy, primarily related to the highly-publicized Keystone pipeline. Despite a flurry of legislative activity earlier this year, the fate of the Keystone pipeline that would expand Canadian oil distribution to the U.S. remains uncertain.
The State Department approved the transfer of ownership of the Express Pipeline to Spectra Energy Partners. This pipeline runs from Hardisty, Alberta, Canada to Casper, Wyoming. The permit allows Spectra to connect, operate, and maintain the existing pipeline facilities at the U.S.-Canada border to transport crude oil.
The State Department also approved the transfer of ownership of a pipeline running from El Paso, Texas to the Rio Grand River on the U.S.-Mexico border to Magellan Pipeline Company. The permit allows Magellan to connect, operate, and maintain existing pipeline facilities at the U.S.-Mexico border to transport liquid petroleum products.
In addition to the Keystone pipeline controversy, cross-border pipelines in general are the subject of significant public and regulatory scrutiny. Another recent example is the Alberta Clipper pipeline from Hardisty, Alberta, Canada to Superior, Wisconsin, where the State Department was accused of accelerating pipeline approval from Enbridge Energy—facts now at issue in litigation filed by a coalition of environmental groups opposed to the pipeline.
Last week, on July 15, 2015, the US EPA revised the 1988 underground storage tank (UST) regulation and the 1988 state program approval (SPA) regulation. Some of these changes had their roots in the Energy Policy Act of 2005, which set out additional requirements in states that received federal RCRA Subtitle I money from EPA. Part of the impetus for this regulation was to apply these changes to Indian country and all states. Other changes relate to revising the regulations in light of technological changes and challenges that have surfaced over the years. The effective date of the regulations is October 13, 2015. Some of the key changes are set out below.
D.C. Circuit Rejects Enviro and Industry Challenges to EPA’s Nonhazardous Secondary Materials Rule; Implications for Combustion Standards Remain
Last week, the D.C. Circuit issued an unpublished per curiam decision in Solvay USA Inc. v. U.S. EPA, No. 11-1189 (D.C. Cir.), rejecting all arguments from both environmentalists and industry against EPA’s non-hazardous secondary material (NHSM) regulations under the Resource Conservation and Recovery Act (RCRA). By way of background, the characterization of non-hazardous secondary materials pursuant to the NHSM has implications under the Clean Air Act (CAA) for the standards by which those materials can be incinerated in combustion units.

As we wish to continue to grow the blog and provide our readers with the information they want to know, Corporate Environmental Lawyer editors, Steven M. Siros and Genevieve J. Essig, encourage you to participate by suggesting new topics. We look forward to continuing to provide content covering the issues that are driving changes in environmental law.
Last week, the EPA-specific listing on the website of the Office of Information and Regulatory Affairs was updated with timelines on the EPA’s regulatory efforts. Of potential interest, in chronological order of expected release, are the following rules:
- May 2015 (Final Rule). Clean Water Rule: Definition of “Waters of the United States”. The U.S. Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers proposed a rule for determining whether a water is protected by the Clean Water Act.
- June 2015 (ANPRM and NRPM). Proposed Greenhouse Gas Endangerment and Cause or Contribute Findings Under CAA Section 231 for Aircraft, and ANPRM on the International Process for Reducing Aircraft GHGs and Future Standards. In this action, EPA will determine whether greenhouse gas emissions from aircraft cause or contribute to air pollution which may reasonably be anticipated to endanger public health or welfare. Concurrent with these proposed findings, EPA will release an Advanced Notice of Proposed Rulemaking (ANPRM) to provide an overview of the International Civil Aviation Organization's (ICAO) efforts to reduce greenhouse gas emissions.
- June 2015 (NPRM). Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles--Phase 2. These second sets of standards would further reduce greenhouse gas emissions and fuel consumption from a wide range of on-road vehicles from semi-trucks to the largest pickup trucks and vans, and all types and sizes of work trucks and buses.
- July 2015 (NPRM). Non-Hazardous Secondary Materials--Additions to List of Categorical Non-Waste Fuels; Other Treated Woods. The Treated Wood Council has submitted a petition for various types of treated wood to be added as categorical non-waste fuels. Materials classed as NHSM can be burned for fuel in lightly regulated boilers rather than more strictly regulated incinerators.
On April 28, 2015, EPA announced the availability of a problem formulation and initial assessment document for the Work Plan Chemical 1,4-Dioxane and opened a 60-day public comment period until June 29. The notice also seeks input on EPA's Office of Pollution Prevention and Toxics' (OPPT) initial concerns about the industrial solvent 1,4-Dioxane.
Following receipt of comments on the problem formulation and initial assessment document and consideration of any additional data or information received, EPA will initiate a risk assessment which is the process to estimate the nature and probability of adverse health and environmental effects in humans and ecological receptors from chemical contaminants that may be present in the environment.
At long last, with a 15-5 bipartisan vote, a Senate bill that would amend the Toxic Substances Control Act (TSCA) moved out of the Senate's Environment and Public Works Committee. Notwithstanding continuing objections from Senator Boxer, the bill that came out of the committee contained a host of changes from the original bill that were intended to address concerns that had been raised by democrats, environmental and public health advocates and U.S. EPA.
Several of these key changes include:
On Friday, April 17th, Jenner & Block partnered with ComEd and Exelon to clean up the 12th Street beach at Northerly Island, in cooperation with the Alliance for the Great Lakes. Our group picked up over 85 pounds of broken glass, plastic beverage containers, food wrappers, cigarettes, and other miscellaneous trash and debris.
The Adopt-a-Beach program is the premier volunteer initiative for the Alliance for the Great Lakes. Teams remove litter and enter results into the Adopt-a-Beach online system to share with local beach authorities, educate the public, and improve the beaches and the health of the Great Lakes.
This picture shows our team after clean up efforts at 12th Street beach:

While much progress has been made in the U.S. to address water quality since the first Earth Day in 1970, increasingly the critical issue of the day is water quantity and specifically sufficient availability of safe water for everyone. According to the World Water Council, 1 in 9 people in the world, or approximately 750 million individuals, lacks access to safe water. In January 2015, the World Economic Forum identified water scarcity as the #1 global risk based upon possible impact to society. These issues exist worldwide, including throughout the U.S.
This month, California Governor Jerry Brown announced the state's first-ever mandatory effort to cope with four years of the worst drought in California's history including a 25% use reduction on cities and towns. There are 5 things you need to know about California's water situation, according to National Geographic's ongoing research and study of water scarcity issues in the Western U.S.:
- The state (and much of the West) relies heavily on snowpack each winter to resupply surface water streams and lakes. Because of a lack of winter storms and record high temperatures this past winter, snowpack in California is at an all-time low. This is the fourth consecutive year that the snowpack has been below normal. The state's hydropower supply is also threatened when snowpack is scarce.
- When surface water supplies are low, hidden water supplies beneath the surface in aquifers, or groundwater, are drilled to make up the shortfall. A large aquifer under the Central Valley is being rapidly depleted to make up for shortfalls in surface water supply. A 2011 study indicated that the Central Valley Aquifer is losing an amount of water each year equivalent to the nearly 29 million acre-feet of water found in Lake Mead, the nation's largest surface reservoir on the Colorado River. (An acre-foot is one acre of ground covered one foot deep in water.) California for the first time last year passed legislation regulating groundwater use, but those restrictions will not come into effect for years.
- While the 25 percent water use restrictions announced last week are intended to help reduce demand, most of the water in California is used for farming, which was largely not included in Brown's announcement on restrictions. California's farms produce and export fruits and vegetables, hay for livestock, and meat and dairy products. Surface water for farms is allocated from state and federal water projects. Water supply restrictions for farmers may be announced soon by the state, but farmers have been drilling groundwater to compensate for surface supply shortages. Last week's rules require only that agricultural operations improve their reporting of water use to the state.
- California is not the only state in the West facing water supply issues. Winter snowpack in Oregon and parts of Washington was far below normal. The Colorado River Basin, which supplies water to Phoenix, Las Vegas, Los Angeles, and San Diego, has also been in a drought for more than a decade, and the river basin's aquifers have been declining, too.
- When California faced a major drought in the late 1970s, fewer than 20 million people lived in the state. Now nearly 40 million live there. While Californians have drastically improved the efficiency of their water use in recent years, if rain and snow do not arrive later this year, the supply of groundwater—much of which is non-renewable—will continue to decline as it is used to make up for surface shortages.
The good news is there are two technical advancements that are currently available to mitigate water scarcity issues—one more mainstream and the other yet to be a "politically correct" option given public perceptions:
- Desalination—this age old process of converting seawater to drinking water is gaining in popularity despite costs and energy demands. A $1B plant is near completion by Poseidon Resources in Carlsbad, CA and will be the largest desalination plant in the Western Hemisphere. 13-15 plants are proposed for California between Los Angeles and San Francisco. There are 300 plants in the U.S. today and over 12,500 plants worldwide, particularly in the Middle East.
- Janicki Bioenergy's Omni Processor—the Bill and Melinda Gates Foundation has invested in this low cost, hyper-efficient sewage treatment plant which produces clean drinking water that meets both FDA and World Health Organization standards AND generates the very energy it requires to run. Janicki Bioenergy, based in Seattle, WA, has a prototype operating in Washington State and this year enters the developing world with a plant in Dekar, Senegal. Here's how it works:
- The sewage sludge is fed into the plant by conveyor belt and dried in a tube that separates solid waste from water. The Omni Processor's intensely hot incinerator reaches 1,000 degrees Celsius, scorching enough to kill all pathogens and, perhaps more important for those living downwind, to operate without the expected offensive smell.
- Converted into vapor, the water is spun in a centrifuge to remove remaining particles and then fed through two layers of filters. Next, it is cooled and condensed, at which point it is filtered one more time. The latest model can yield 86,000 liters of pure drinking water each day.
- The remaining solids are then fed into an incinerator, yielding a high-powered steam that drives a generator, which in turn produces the very electricity that runs the plant (the Dakar unit produces 150 kW per day), plus excess energy that can be diverted back to the surrounding community. Another byproduct is a phosphorus-rich, disease-free ash that can be used as fertilizer. And the circle of life continues.
While some solutions exist, water remains a precious natural resource and there is no alternative. Every sector of society needs to do their part to conserve, protect and restore water resources in conjunction with governmental action to regulate quality concerns, improve infrastructure and water distribution systems, and address use limitations when appropriate.

On October 5, 2012, President Obama signed into law the Hazardous Waste Electronic Manifest Establishment Act (PDF), which authorizes the EPA to implement a national electronic manifest system. Commonly referred to as "e-Manifest," this national system is envisioned to be implemented by the EPA in partnership with industry and states.
EPA issued the e-manifest final rule, effective August 6, 2014, authorizing the use of electronic hazardous waste manifests that will become available when EPA establishes a new electronic hazardous waste manifest system (79 Fed. Reg. 7518, February 7, 2014). The modification will provide waste handlers with the option to complete, sign, transmit, and store manifest information electronically in the electronic system. States that currently receive and collect paper manifest copies will receive copies of manifest data electronically from the system.
EPA Connect, the Agency's official blog, provided some updates this week on the status of the e-Manifest implementation process. EPA reported that an important next step is to establish the initial fee structure for users of the system. EPA is working with states and stakeholders to create this fee proposal. According to the blog, EPA anticipates the proposed rule establishing the fee model for the system to be available for public comment by May 2016.
When implemented, EPA estimates this rule will impact 160,000 entities in at least 45 industries that ship off-site, transport, or receive approximately 5.9 million tons of RCRA hazardous wastes annually. These entities currently use between 4.6 and 5.6 million EPA Uniform Hazardous Waste Manifests.
Further insights and regulatory developments are detailed at http://www.epa.gov/osw/hazard/transportation/manifest/e-man.htm.
EPA has proposed one-time reporting and record keeping requirements on nanoscale chemical substances in the marketplace. The proposed rule contains a 90-day public comment period. After the comment period, EPA will review and consider those comments before issuing any final rule. EPA also anticipates a public meeting during the comment period to obtain additional public input.
Specifically, EPA proposed requiring companies that manufacture or process (or intend to manufacture or process) chemical substances in the nanoscale range to electronically report information, including the specific chemical identity, production volume, methods of manufacture, processing, use, exposure and release information, and available health and safety data. The proposed rule would apply to chemical substances that have unique properties related to their size. The proposed rule contains exclusions for chemical substances in the nanoscale range that would not be subject to the rule. In addition to this proposed one-time reporting on chemical substances manufactured or processed as nanoscale materials already in commerce, EPA currently reviews new chemical substances manufactured or processed as nanomaterials prior to introduction into the marketplace to ensure that they are safe.
Chemical substances that have structures with dimensions at the nanoscale -- approximately 1-100 nanometers (nm) -- are commonly referred to as nanoscale materials or nanoscale substances. A human hair is approximately 80,000-100,000 nanometers wide. These chemical substances may have properties different than the same chemical substances with structures at a larger scale, such as greater strength, lighter weight, and greater chemical reactivity. These enhanced or different properties give nanoscale materials a range of potentially beneficial public and commercial applications; however, the same special properties may cause some of these chemical substances to behave differently than conventional chemicals under specific conditions.
EPA is proposing this new requirement under TSCA Section 8(a) to determine if further action, including additional information collection, is needed.
More information about the proposed rule, including the Federal Register notice, EPA fact sheet and press release, are available at http://www.epa.gov/oppt/nano/.
