On August 13, EPA finalized Clean Water Act (Act) Section 304(a) recommended criteria for phosphorus and nitrogen in lakes and reservoirs. The new recommendations incorporate scientific models that states and tribes with treatment as state status can use to establish numeric water quality criteria for phosphorus and nitrogen, and they mark an important milestone in EPA’s long-running war on excess nutrients in the nation’s surface waters. In the new recommended lakes criteria, EPA is embracing a stressor-response approach to managing nutrients, instead of the least-disturbed reference method. This is a significant move for the agency and has the potential to set a positive precedent going forward for EPA and state and tribal regulators to re-evaluate the utility of the reference method approach in other contexts.
EPA Signals More Stringent Regulation for Steam Electric Power Generators
EPA announced yesterday its intent to revise some portions of the 2020 Steam Electric Effluent Limitation Guideline Reconsideration Rule (2020 ELG Rule). EPA’s press release and the pre-publication version of its Federal Register notice sent a clear message that the agency is aiming at membrane technology to control flue gas desulfurization (FGD) wastewater discharges from coal-fired power plants. The notice also states that the agency will reconsider the technology selected for bottom ash transport, and it may revise or eliminate the subcategories created by the 2020 ELG Rule for high-flow facilities, low-utilization facilities, and for facilities that commit to retire or repower coal-fired units by 2028.
EPA Announces Reconsideration and Potential Revision of the Clean Water Act Section 401 Final Rule
On May 27, the Environmental Protection Agency (EPA) announced its intent to reconsider the Clean Water Act (CWA) Section 401 final rule issued by the Trump administration in June 2020 (Final Rule).
Second Circuit Enforces the Clean Water Act Section 401 One-Year Time Limit
On March 23, the Second Circuit issued its opinion in N.Y. Dep’t of Enviro. Conservation v. FERC, Case No. 19-1610 (i.e., the “Empire Pipeline” case). The case concerns the Federal Energy Regulatory Commission’s (FERC or Commission) determination that the New York State Department of Environmental Conservation (NYSDEC) waived its water quality certification authority with regard to FERC’s issuance of a gas pipeline certificate when NYSDEC sought to extend its review period beyond the one-year deadline under Section 401 of the Clean Water Act (CWA or Act) by agreeing with the applicant to “post-date” the filing date of its water quality certification application by several weeks.
EPA Publishes Advance Notice of Proposed Rulemaking in Preparation for Crafting PFAS Effluent Limitations Guidelines
On March 17, the U.S. Environmental Protection Agency (EPA) published an Advance Notice of Proposed Rulemaking (ANPRM) that puts forth 28 questions directed at manufacturers and formulators of per- and polyfluoroalkyl substances (PFAS). The agency intends to use the ANPRM and comments it receives to initiate formal rulemaking to establish effluent limitations guidelines (ELGs) for facilities that manufacture or blend PFAS with other chemicals or products, likely at least initially as an amendment to the existing guidelines governing the “Organic Chemicals, Plastics and Synthetic Fibers” (OCPSF) industrial sector.
USEPA Advances Toward Regulation of PFAS in Drinking Water
Climate change and environmental justice are currently dominating the conversation in the environmental legal community, but 2021 promises to be an extremely active year for one of the most challenging environmental issues of this era — the emergence of per- and polyfluoroalkyl substances (PFAS) as a significant public health concern. The U.S. Environmental Protection Agency (USEPA) demonstrated its continued commitment to implementing the national PFAS Action Plan by announcing on February 22 two important steps toward establishing federal drinking water standards for PFAS compounds under the Safe Drinking Water Act (SDWA).
Illinois EPA Issues Health Advisories for Four Per- and Polyfluoroalkyl Substances (PFAS)
On January 28, the Illinois Environmental Protection Agency (Illinois EPA) announced the issuance of health advisories for four (4) per- and polyfluoroalkyl substances (PFAS) compounds in accordance with the Illinois Part 620 groundwater regulations (35 Ill. Adm. Code Part 620). Health advisories are issued when a chemical substance that is harmful to human health, and for which no numeric groundwater standard exists, is detected and confirmed in a community water supply well (35 Ill. Adm. Code 620.605). The four (4) PFAS compounds for which Illinois health advisories were issued are PFBS, PFHxS, PFHxA, and PFOA.
