California regulators have announced that the comment period for a recent proposal, Supplemental Guidance: Screening and Evaluating Vapor Intrusion, has been extended to June 1, 2020, and public workshops and webinars originally scheduled for April have been postponed until further notice.

Vapor intrusion occurs when contamination moves from groundwater and soil beneath a structure into the air, accumulating in occupied areas where they can result in safety hazards or health effects. Common vapor-forming chemicals include volatile organic compounds including trichloroethylene (TCE), mercury, polychlorinated biphenyl (PCB), and certain pesticides. Testing for vapor intrusion is an important step in investigating a potential development site, and in ensuring the health and safety of existing residential and commercial buildings.Continue Reading Update – New California Supplemental Vapor Intrusion Guidance Comment Period Extended, Trainings Postponed

As reported previously, California agencies are providing clarification and directives to guide regulatory compliance following Governor Gavin Newsom’s state-wide “stay at home” order issued on March 19, 2020. More specific guidance has now been issued by the State Water Resource Control Board (SWRCB) for Public Water Systems, and by the South Coast Air Quality Management District for all regulated entities.

Notably, although EPA has announced that enforcement discretion will be exercised in cases where routine compliance is not reasonably practicable, the Agency recognizes the authority of states and tribes to determine their own enforcement policies. Thus, California-regulated companies also must track how California agencies are approaching compliance during COVID-19 to ensure ongoing compliance.Continue Reading Update – California Agencies Issue Additional Guidance on Environmental Compliance During COVID-19 Emergency

California agencies are beginning to provide clarification and directives to guide regulatory compliance following local “shelter in place” orders to slow the spread of COVID-19 in the San Francisco Bay Area, and Governor Gavin Newsom’s state-wide “stay at home” order issued on March 19, 2020. While the State Department of Public Health is taking the lead in coordinating the state-level response, other regulatory agencies responsible for essential services and facilities have begun to issue their first formal directives related to environmental compliance and safety.

The emphasis of regulatory directives thus far are clear: all requirements related to critical infrastructure remain in effect, with special provisions for immediate notification if there are circumstances or current government directives that could impede timely compliance.Continue Reading Update – California Agencies Issue Guidance for Regulatory Compliance As COVID-19 Containment Orders Go Into Effect

On February 20, 2020, the U.S. Environmental Protection Agency (EPA) announced its intent to publish a preliminary regulatory determination under the Safe Drinking Water Act (SDWA) for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). Publication will initiate a 60-day notice and comment period that represents the first step toward the adoption of Maximum Contaminant Levels (MCLs) and Maximum Contaminant Level Goals (MCLGs) for PFOA and PFOS, two of the best-understood and most common compounds under the umbrella of perfluoroalkyl substances (PFAS).

On January 31, 2020, California announced proposed changes to warning requirements under the Safe Drinking Water and Toxic Enforcement Act of 1986, commonly known as Proposition 65, by releasing a Notice of Proposed Rulemaking (“Proposal”). Among other things, the changes are intended to clarify on-line warning requirements (through a website or using a mobile phone app) and catalog warning requirements. The Proposal also includes revised requirements specific to the sale of alcoholic beverages through delivery services, reflecting the provisions of an enforcement action settlement currently being negotiated by the Attorney General.

New federal reporting requirements for per- and polyfluoroalkyl substances (PFAS) went into effect on January 1, 2020. The National Defense Authorization Act for FY 2020 (NDAA), signed into law on December 20, 2019, required EPA to add certain PFAS to the federal Toxics Release Inventory (TRI) list of reportable chemicals.

The NDAA identified fourteen specific PFAS chemicals for addition to the TRI list, and directed EPA to add other substances that met two criteria: (1) they were subject to a significant new use rule (SNUR) under the Toxic Substances Control Act (TSCA) on or before December 20, 2019, and (2) they were identified as active in commerce on the TSCA Inventory that was published in February 2019. Among the new additions are some of the best-known and most-studied substances, including PFOA (perfluorooctanoic acid), PFOS (perfluorooctane sulfonate), and GenX chemicals (including hexafluoropropylene oxide dimer acid).Continue Reading Toxic Release Inventory Expanded to Include PFAS, with 160 New Reportable Chemicals and Counting
