EPA Extends Deadline for Filing Under Chemical Data Reporting Rule to January 2021

The U.S. Environmental Protection Agency (EPA) has extended the deadline for submissions due under the Chemical Data Reporting (CDR) Rule from November 30, 2020, to January 29, 2021. The CDR report covers chemical manufacturing and processing for the four calendar years of 2016 through 2019. We have covered the scope and application of the CDR rule here.

Sierra Club and Others Challenge EPA Coal Ash Rule

On November 2, 2020, several environmental interest groups including the Sierra Club and Earthjustice filed suits in the U.S. Courts of Appeals for the Fourth and D.C. circuits challenging the Environmental Protection Agency’s (EPA) recent Steam Electric Reconsideration Rule (SERR), which rolled back certain Obama-era effluent discharge limitations on coal-fired power plants.

EPA Finalizes Project Emissions Accounting Rule for New Source Review Permitting Determinations

On October 22, 2020, the U.S. Environmental Protection Agency (EPA) published a prepublication version of a final rule clarifying the process for existing air pollution sources to determine whether the New Source Review (NSR) permitting program applies to proposed projects. The new rule clarifies and confirms that project emissions accounting can be considered during Step 1 of the two-step NSR applicability test, meaning that both emissions increases and decreases from the proposed modification will be considered. The two steps of the NSR applicability test consist of a first step to determine whether a proposed project will cause a significant emission increase of a regulated NSR pollutant and, if it would, the second step determines if there will be a significant net emission increase of the same regulated NSR pollutant considering all other contemporaneous emissions increases and decreases.

EPA Rule Establishing Requirements and Procedures for Guidance Documents Will Be Effective November 18

The U.S. Environmental Protection Agency (EPA) has published in the Federal Register a final rule establishing the agency’s management of guidance documents consistent with the Executive Order 13891, “Promoting the Rule of Law Through Improved Agency Guidance Documents,” which will become effective on November 18.

EPA Revises National Emission Standards for Hazardous Air Pollutants General Provisions to Allow Major Sources to Reclassify as Area Sources

On October 1, 2020, the U.S. Environmental Protection Agency (EPA) issued a prepublication version of a final rule under the Clean Air Act that will allow major sources of hazardous air pollutants (HAP) to reclassify as area sources if the source reduces its potential to emit HAPs below the major source threshold (10 tons per year of any single HAP or 25 tons per year of any combination of HAPs). EPA had previously applied a “once in, always in” interpretation through a May 1995 policy memorandum issued by John Seitz, then-Director of EPA’s Office of Air Quality Planning and Standards. Under that policy, a facility designated as a major source on the first substantive compliance date of an applicable major source National Emission Standards for Hazardous Air Pollutants rule had to retain its major source status regardless of whether the source subsequently reduced its potential to emit below major source thresholds. But on January 25, 2018, EPA withdrew the May 1995 policy, laying the groundwork for EPA’s action here.

EPA Extends Deadline for High-Speed Commercial Vessels to Install Tier 4-Certified Marine Diesel Engines

On October 2, 2020, the U.S. Environmental Protection Agency (EPA) issued a final rule amending the national marine diesel engine program set forth in 40 C.F.R. Part 1042. Through the amendment, EPA is providing boat manufacturers additional lead time to install Tier 4 marine diesel engines in certain high-speed commercial vessels. Tier 4 standards — applicable to marine diesel engines at or above 600 kilowatts — were expected to be phased in between 2014 and 2017 and were based on achieving emissions reductions through aftertreatment technology, such as selective catalytic reduction. While these engines are mostly used in various types of large workboats and passenger vessels, certain engines are used in high-speed vessels that need compact and powerful engine designs. After the Tier 4 standards were fully in effect, some high-speed boat manufacturers informed EPA that they were unable to find certified Tier 4 engines with suitable performance characteristics for the vessels they needed to build.

California Governor Directs State to Develop Near-Future Zero-Emission Vehicle Sales and Operation Mandates

On September 23, 2020 California Governor Gavin Newsom issued Executive Order N-79-20, expressing the goals that:

  • by 2035, 100% of all in-state sales of new passenger cars and trucks will be zero-emission vehicles (“ZEV”);
  • by 2045, 100% of all medium-and heavy-duty vehicles in the state be zero-emission for all operations where feasible (and the same goal for drayage trucks by 2035); and
  • by 2035, the State will transition to 100% zero-emission off-road vehicles and equipment (where feasible).

U.S. Legislators and Regulators Bring New Attention to PFAS

Late summer this year has brought a surge of activity related to per- and polyfluoroalkyl substances (PFAS). The U.S. Environmental Protection Agency (EPA) research office reported at an industry conference last week that it was evaluating ways to divide PFAS compounds into categories for purposes of risk assessment and risk management. This aligns with the approach supported by industry groups but conflicts with demands from environmental advocates that EPA study each compound separately. Because of the complexity and number of individual PFAS molecules, which number in the thousands, categorization would likely expedite the review process.
