Feds restore WA water quality standards for chemical discharges

National News
By Isabella Breda; The Spokesman Review SEATTLE - In a reversal of Trump administration policies, the U.S. Environmental Protection Agency this week reinstated federal water quality standards for chemicals discharged into Washington state waterways. The final rule signed Monday would ensure polluters stay within federally established levels of chemicals or conditions in a body of water that are not expected to cause adverse health effects. Through the years, the water quality standard for polychlorinated biphenyls, or PCBs — chemicals found in dyes, paint, building materials, coolants and other products — have been a point of contention. Industry leaders, like paper and pulp manufacturers, previously argued there was no technology available to bring wastewater discharge of PCBs to the low levels that were required. Sometimes these standards are aspirational, said Bill…

County will fund lake water analysis

Idaho News
By Kaye Thornbrugh; Coeur d'Alene Press COEUR d’ALENE — Kootenai County commissioners voted Wednesday to commit $50,000 to a project analyzing lake water samples for trace and toxic metals.

EPA Adds Four New PFAS to Toxic Release Inventory

National News, Research
By Joseph Zaleski and Samuel Boxerman; Sidley Energy Blog As part of its continued focus on per- and polyfluoroalkyl substances (PFAS) regulations, the U.S. Environmental Protection Agency (EPA) has added four PFAS substances to the Toxics Release Inventory (TRI) list, including PFBS (perfluorobutane sulfonic acid) and potassium perfluorobutane sulfonate as well as two compounds listed at by their chemical identifier numbers — CASRN 65104-45-2 and CASRN 203743-03-7. EPA’s decision to add these PFAS to the TRI requires facilities that manufacture, process, or otherwise use these PFAS chemicals to include them in annual reports made to EPA pursuant to the Emergency Planning and Community Right-to-Know Act starting this reporting year. The 2020 National Defense Authorization Act (NDAA) immediately added 172 PFAS chemicals to the TRI and required annual facility reporting. The NDAA also provided…
