Last Friday, White House Chief of Staff Reince Priebus issued a memorandum directing all agencies, including EPA, to freeze new or pending regulations. The freeze effects regulations at a variety of stages of finality. Under the Administration’s direction, the following actions are being taken by EPA and other agencies:
- Regulations that have been finalized but not yet been sent for publication in the Federal Register will not be sent until reviewed by someone selected by the President.
- Regulations that have been sent to the Federal Register but not published will be withdrawn.
- Regulations that have been published in the Federal Register but have not reached their effective date will be delayed for at least 60 days for review (until March 21, 2017).
Following through on this direction, EPA released a notice that will be published in the Federal Register on January 26, 2017, delaying implementation of all published rules that have yet to take effect until at least March 21, 2017. The delayed rules include EPA’s Risk Management Program (RMP) facility safety rule, the 2017 Renewable Fuel Standard (RFS) targets, and the addition of vapor intrusion to Superfund NPL site scoring.
By E. Lynn Grayson:
The Department of Homeland Security (DHS) continues to implement recent changes to the Chemical Facility Anti-Terrorism Standards (CFATS) program. DHS updated its data platform and portal that will require regulated facilities to resubmit the Top-Screen information that originally was submitted in the 2008 time frame.
The DHS last year issued notice in the Federal Register (81 FR 47001, July 20, 2016) announcing revisions to its CFATS program, effective October 1, 2016. The main objective of the notice was to advise that the DHS was transitioning to revised versions of the applications for the Chemical Security Assessment Tool (CSAT), the CSAT Security Vulnerability Assessment (SVA) and the CSAT Site Security Plan (SSP). DHS implemented a three-step process to transition to these new versions: 1) temporarily suspended, effective July 20, 2106, the requirement for CFATS chemical facilities of interest to submit a Top-Screen and SVA; 2) replaced the current applications with CSAT 2.0 beginning in September 2016; and 3) reinstated the Top-Screen and SVA submission requirements effective October 1, 2016.
At this time, regulated facilities do not need to take any action unless notified by DHS. DHS began sending out notices to individual facilities every two weeks once the roll-out started in October 2016. Each batch of notifications will include sites from all risk-based tiers and also will include sites that have previously tiered out or are otherwise exempt from CFATS.
Other key highlights and insights include:
- While there is no requirement to do so, regulated facilities may choose to proactively resubmit a Top-Screen utilizing the new CFATS CSAT. Once notified, facilities will have 60 days to submit this updated and/or new Top-Screen.
- No changes have been made to the Appendix A identifying the chemicals of interest (COI) and the associated screening threshold quantity (STQ).
- CSAT 2.0 makes some changes in terms of how and when information is reported. For example, information previously collected through the SVA now may be collected through the Top-Screen. Other information collected in the past in the SVA now will be collected in the SSP.
- The new online SSP will come partially pre-populated from the new Top-Screen and the new SVA submissions as well as information from previous submissions.
In general, CFATS requires chemical facilities report COIs at or above the STQ through submission of a Top-Screen to DHS. Thereafter, DHS decides whether to impose security requirements upon the facility at issue. CFATS requirements apply to facility owners and operators that possess, consume, sell or create various chemicals that could be useful to conducting a terrorist event. There are over 300 COIs including commonly used chemicals such as ammonia, propane, hydrogen peroxide, flammables, bromine, aluminum, nitric oxide and vinyl chloride. Original compliance deadlines for submission of Top-Screen information was in 2008 time frame.
Facilities that previously submitted a Top-Screen survey, even those previously determined to be exempt from the CFATS requirements, will be required to resubmit the Top-Screen information using the new data CSAT 2.0 platform and portal. DHS will notify each facility about these new requirements and facilities will have 60 days to submit the new Top-Screen information. Facilities are welcome to be proactive and submit an updated Top-Screen prior to any DHS notification.
For further insight into these new requirements, please see the Federal Register notice at https://www.federalregister.gov/documents/2016/07/20/2016-16776/chemical-facility-anti-terrorism-standards or visit the CFATS program website at https://www.dhs.gov/chemical-facility-anti-terrorism-standards .
The Occupational Safety and Health Administration (OSHA) published a final rule on Occupational Exposure to Beryllium in the Federal Register on January 9, 2017. The final rule reduces the permissible exposure limit (PEL) for beryllium to 0.2 μg/m3, averaged over 8-hours. The previous PEL for beryllium, established more than 40 years ago, was 2.0 μg/m3. The rule also establishes a new short term exposure limit for beryllium of 2.0 μg/m3, over a 15-minute sampling period.
As we discussed previously on this blog, OSHA proposed this rule on August 7, 2015 and took extensive public comment before issuing this final version. OSHA estimates that approximately 62,000 workers are exposed to beryllium in their workplaces and that the rule will save almost 100 lives from beryllium-related diseases and prevent 46 new cases of chronic beryllium disease each year, once the effects of the rule are fully realized.
On December 7, 2016, EPA published a proposed rule to ban certain uses of trichloroethylene (TCE) under section 6(a) of the Toxic Substances Control Act (TSCA) due to risks to human health from those uses. The proposed rule would prohibit the manufacture (including import), processing, distribution in commerce and commercial use of TCE for aerosol degreasing and for spot cleaning in dry cleaning facilities.
As we previously reported on this blog, EPA recently included TCE on its list of the first 10 chemicals it will evaluate broadly for potential risks to human health and the environment pursuant to requirements of the 2016 TSCA Reform Act. In a 2014 risk assessment, EPA identified serious risks to workers and consumers associated with TCE uses, concluding that the chemical can cause a range of adverse health effects, including cancer, development and neurotoxicological effects, and toxicity to the liver.
On November 29, 2016, EPA announced the first 10 chemicals it will evaluate for potential risks to human health and the environment under the new Toxic Substances Control Act (TSCA) Reform Act, which was signed into law back in June. The TSCA Reform Act required EPA to publish this list of priority chemicals and begin the risk evaluation process on these chemicals by December 19, 2016. By the end of 2019, EPA will be required to have at least 20 chemical risk evaluations in process at any given time.
The first 10 chemicals to be evaluated by EPA are:
Cyclic Aliphatic Bromide Cluster
Pigment Violet 29
Tetrachloroethylene, also known as perchloroethylene
This list will be published in the Federal Register in the coming weeks, at which point it will trigger several statutory deadlines for these 10 chemicals:
- EPA must release a scoping document for each chemical within 6 months.
- EPA must complete risk evaluations for each chemical within three years.
- If the risk evaluation determines that a chemical presents an unreasonable risk to humans and the environment, EPA must mitigate that risk within two years.
More information on the TSCA Reform Act and EPA’s recent actions can be found on EPA’s website.
Mayor Rahm Emanuel and Cook County Board President Toni Preckwinkle recently launched an unprecedented effort to generate new industrial investment in Chicagoland neighborhoods. The Industrial Growth Zones program will accelerate neighborhood development in seven designated areas over the next three years by removing longstanding hurdles to development and providing a broad set of services to support property owners and industrial businesses. The purpose of the program to spur economic growth and generate real, sustainable jobs by promoting investment and industrial development in Chicago neighborhoods.
The State of Washington and the Confederated Tribes of the Colville Reservation are trying to expand the reach of CERCLA, but have been blocked, once again, by the U.S. Court of Appeals for the Ninth Circuit. The case of Pakootas v. Teck Cominco Metals, Ltd., Case No. 15-35228 (9th Cir. Panel decision July 27, 2016), involves claims by the State of Washington and the Tribes against a smelter located in British Columbia. In August, a three-judge panel of the Ninth Circuit ruled in favor of the defendants in this case. Yesterday, the full Ninth Circuit denied the plaintiffs’ petition for rehearing.
The case involves hazardous air emissions (lead, arsenic, cadmium and mercury), which were emitted from the smelter’s smokestack, carried by wind, and deposited on the Upper Columbia River Superfund Site in Washington. Plaintiffs maintained that such air emissions constituted “disposal” of hazardous waste under CERCLA, thus the smelter had arranged for the disposal of hazardous waste pursuant to CERCLA and was a responsible party at the Superfund Site.
2016 Democratic Party Platform: Combat Climate Change, Build a Clean Energy Economy, and Secure Environmental Justice
Last week, we examined the key environmental issues raised in the 2016 Republican platform. Now that the political focus has shifted from Cleveland to Philadelphia, where Democrats are holding their convention, we will examine what the Democratic Party has to say about its environmental priorities in the 2016 Democratic Party Platform. One of the Democratic Party platform’s 13 main sections is entitled “Combat Climate Change, Build a Clean Energy Economy, and Secure Environmental Justice.” Environmental issues are also raised in the section titled “Confront Global Threats”, which discusses “Global Climate Leadership.”
In the platform’s preamble, the Democrats state that:
Democrats believe that climate change poses a real and urgent threat to our economy, our national security, and our children’s health and futures, and that Americans deserve the jobs and security that come from becoming the clean energy superpower of the 21st century.
Other key positions from the Democratic environmental platform include:
Jenner & Block Partners E. Lynn Grayson and Gabrielle Sigel have been named “Energy & Environmental Trailblazers” by The National Law Journal. The list honors people who have “made their mark in various aspects of legal work in the areas of energy and environmental law.”
The profile of Ms. Grayson notes that she was appointed general counsel for the Illinois Emergency Services and Disaster Agency soon after the agency took over enforcement responsibility for the state’s Emergency Planning and Community Right-to-Know Act. When she moved into private practice in Chicago, she became involved in the first REIT case involving environmental issues; since moving to Jenner & Block, she has done a great deal of international due diligence. Ms. Grayson observes that the future of environmental law will involve international transactions as well as domestic work, particularly around energy and renewable energy.
The profile of Ms. Sigel notes that she focuses on the intersection of workplace health and the environment. The profile highlights one of her cases in which the water supply in retail and medical offices became contaminated, and a number of state agencies became involved. As for the future, Ms. Sigel observes that the lines between organizations will increasingly blur. “Whether it’s business, regulatory agencies, community groups or NGOs, you have to look at issues holistically, and not in a superficial way,” she says.
Late on June 7, 2016, the Senate voted in favor of the Frank R. Lautenberg Chemical Safety for the 21st Century Act (HR 2576) (a/k/a the TSCA Reform Act). The TSCA Reform Act regulates the manufacture, transportation, sale and use of thousands of chemicals, and provides a much needed update to the 40 year old Toxic Substances Control Act (TSCA). The TSCA Reform Act had been passed by the House in May, with overwhelming support. It was held up recently in the Senate by an objection from Senator Rand Paul (R-Ky.), who argued that he needed more time to review the complex new law. But, Senator Paul dropped his objection on June 7th, and a vote was quickly held.
The TSCA Reform Act is widely seen as an improvement over the outdated TSCA. The American Chemical Counsel praised the TSCA Reform Act as “truly historic”. Others, however, were disappointed that the TSCA Reform Act preempted state laws on chemical safety, instead of setting a floor and letting state’s set more stringent standards.
President Obama is expected to sign the TSCA Reform Act into law very soon, as the White House had endorsed the Act after it passed the House of Representatives in May.
EPA’s woes over alleged mismanagement of the Gold King Mine spill in August 2015 continue with a new lawsuit recently filed by the State of New Mexico in federal district court in Albuquerque. The lawsuit names the EPA as a defendant, along with an EPA environmental contractor and mine owners contributing to the mismanagement of reclamation waters. New Mexico contends that the Agency has not done enough to remedy the toxic release of a flood of wastewater contaminated with an estimated 880,000 pounds of heavy metals into local rivers.
New Mexico’s suit seeks a declaratory judgment that the contractor and mine owners violated the Resource Conservation and Recovery Act, as well as compensatory and punitive damages for alleged negligence and gross negligence. New Mexico also is asking for a declaratory judgment against all defendants under the Comprehensive Environmental Response, Compensation and Liability Act.
Although the suit does not specify damages, attorneys for New Mexico said communities are owed at least $7 million for emergency response costs and third-party monitoring of water quality. They said the defendants should pay another $140 million in damages for estimated economic harm. This calculation estimated the harm done to rivers that are critical for agricultural and ranching use; to the Navajo Nation, which owns a tract of land the size of a small state that was affected; and to recreation that provides a significant amount of New Mexico’s income.
The New Mexico Attorney General is requesting full and just compensation for the environmental and economic damage caused by EPA’s spill. The lawsuit alleges that the effects of EPA’s spill were far worse than reported. New Mexico Environmental Department Cabinet Secretary Ryan Flynn has stated publicly that “from the very beginning, the EPA failed to hold itself accountable in the same way that it would a private business.”
While EPA declined to formally comment on the lawsuit, an Agency spokesperson advised that the EPA has taken responsibility for the spill and already paid the State of New Mexico $1.3 million.
The lawsuit is the first state litigation against the EPA over the spill. Other states impacted include Arizona, Colorado, Utah, and the Navajo Nation.
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.
On Wednesday, March 16, 2016, Jenner & Block partners E. Lynn Grayson and Allison Torrence will be speaking at a Chicago Bar Association CLE Seminar titled "Major Cases and Regulatory Changes in Environmental Law."

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 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.

On Wednesday, February 10, 2015 from 1:00 p.m.-2:30 p.m. (Central), Partner Steven Siros will be presenting at a DRI webinar titled “Relying on Chemical Fingerprinting as a Line of Evidence in Allocation Proceedings”. 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.
In 2015, the United States Court of Appeals for the 9th Circuit vacated U.S. EPA’s registration of the insecticide sulfoxaflor, finding that U.S. EPA lacked adequate data to ensure that its registration would not harm non-target species, and more specifically, bees. Following the 9th Circuit’s decision in September 2015, U.S. EPA reversed its position on two other pesticide registrations. In October 2015, U.S. EPA indicated that it planned to ban the agricultural use of chlorpyrifos notwithstanding U.S. EPA's previously stated intention to work with industry to mitigate the risks as opposed to an outright ban. In November 2015, U.S. EPA sought to voluntarily vacate its prior registration of Enlist Duo on the basis that U.S. EPA had obtained new data suggesting that the combined toxicity of its two ingredients (glyphosate and 2,4-D) was higher than originally believed. U.S. EPA was facing litigation in the 9th Circuit with respect to both of these pesticides which likely played a role in those decisions. In addition, U.S. EPA’s anticipated decision with respect to the reregistration of glyphosate has been delayed on multiple occasions and is now expected sometime in 2016.
These actions are all suggestive that U.S. EPA has elected to adopt a more stringent approach with respect to its risk reviews of pesticides under the Federal Insecticide, Fungicide and Rodentcide Act (FIFRA) and the Endangered Species Act (ESA). Such an approach is likely to result in significant delays in getting pesticide products registered and to the market. We will continue to follow these issues as we await U.S. EPA’s glyphosate reregistration decision which is likely to be the next significant U.S. EPA action in the FIFRA arena.
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).

IARC’s Classification of Red Meat and Processed Meats as Carcinogenic Exposes Food Manufacturers, Distributers, and Retailers to Proposition 65 Liability
The Internet was buzzing yesterday with news that the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) has classified red meat as a Group 2A carcinogen (“probably carcinogenic to humans”) and processed meat as a Group 1 carcinogen (“carcinogenic to humans”). In general, IARC evaluates the environmental causes of cancer in humans, including chemicals (e.g., formaldehyde), complex mixtures (e.g., air pollution), physical agents (e.g., solar radiation), biological agents (e.g., hepatitis B virus), and personal habits (e.g., tobacco smoking). IARC has long played a role as a source of scientific information that carries weight in federal and state regulation of potentially harmful substances and toxic tort lawsuits involving such substances.

A recent decision by the Seventh Circuit Court of Appeals may significantly lower the causation bar for plaintiffs in toxic tort cases. In the case C.W. & E.W. v. Textron, Inc., the Seventh Circuit was called on to evaluate a district court decision that excluded plaintiffs' experts for failing to meet the admissibility requirements of Federal Rule of Evidence 702 and Daubert v. Merrell Dow Pharmaceuticals, Inc. The Seventh Circuit's analysis of the district court's decision was relatively straightforward and the Seventh Circuit acknowledged that the district court had carefully considered the methodology employed by plaintiffs' experts. The Seventh Circuit concluded that the district court had properly exercised its gatekeeper role under Daubert in concluding that there simply was too great an analytical gap between the data and the expert opinion being offered such that the opinion amounted to nothing more than the ipse dixit of the expert.
