On November 30, 2020, the Environmental Protection Agency (EPA) announced two important steps to address per- and polyfluoroalkyl (PFAS.)
First, the agency issued a memorandum detailing an interim National Pollutant Discharge Elimination System (NPDES) permitting strategy for addressing PFAS in EPA-issued wastewater and stormwater permits. In this memorandum, the EPA advises permit writers to consider including PFAS monitoring at facilities where these chemicals are suspected to be present in wastewater discharges, including from municipal separate storm sewer systems and industrial stormwater permits. The agency’s interim strategy also encourages the use of best management practices where appropriate to control or abate the discharge of PFAS. Note that EPA, not the State, is the permitting authority for NPDES for three states (Massachusetts, New Hampshire and New Mexico), the District of Columbia, most U.S territories, including Puerto Rico, Native American Indian Country and certain federal facilities.

The second initiative
Includes the development of analytical methods to test for PFAS in wastewater testing and other environmental media, including surface water, groundwater, leachate, soil, sediment, biosolids, and fish tissue. The agency has released a list of 40 PFAS chemicals that will be subject to testing using these analytical methods (https://www.epa.gov/cwa-methods/cwa-analytical-methods-and-polyfluorinated-alkyl-substances-pfas). These new methods would be an addition to the Method 533 and Method 537.1 that are already approved and can measure 29 PFAS chemicals in drinking water. EPA anticipates that these new analytical methods will be finalized in 2021.
When these two initiatives are finalized, they will ensure federally enforceable monitoring for PFAS Consider reviewing your facility’s processes if you have an EPA-issued wastewater or stormwater permit to determine if your facility discharges PFAS into the environment. Your facility may be impacted by these initiatives when your wastewater or stormwater permit is renewed.

Support an Integrated EHS/ESG Management System
June 10, 2022
What is FERC and NERC Compliance? At its May 2022 meeting, the Federal Energy Regulatory Commission (FERC) issued Order No. 881-A, to clarify a December 2021 order that represented a major change in utility operating practices and planning. In the new order, FERC denied requests for rehearing Order No. 881, and reaffirmed its Ambient Adjusted Ratings (AAR) pronouncements. These actions will have a significant impact on NERC compliance programs related to both PRC standards and facilities ratings. Utilities should review the Order’s requirements and prepare for changes needed to remain compliant. Order 881-A Requirements The new FERC order specifically requires: Public utility transmission providers to deliver transmission service; Regional transmission organizations and independent system operators (RTO/ISO) to establish and implement the systems and procedures necessary to allow transmission owners to electronically update transmission line ratings at least hourly; Public utility transmission providers to use uniquely determined emergency ratings Public utility transmission owners to share transmission line ratings and transmission line rating methodologies with their respective transmission provider(s) and with market monitors in RTOs/ISOs; and Public utility transmission providers to maintain a database of transmission owners’ transmission line ratings and transmission line rating methodologies on the transmission provider’s Open Access Same-Time Information System (OASIS) site or other password-protected websites.

How to Use an Integrated Approach To Manage EHS and ESG Risks
April 20, 2022
Inverter-based resources are being added to the power system at an increasing rate due to renewable energy mandates and clean energy goals. Because the current NERC standards were written long before this trend, many are being updated to ensure continued reliability and resilience under new and emerging conditions. Most notably, changes to PRC-024-3 in support of inverter-based generation performance are going into effect in October of this year. Interconnection programs and documentation procedures may need to be updated in order to maintain compliance. Generation Losses Highlight Need for Change From August 2016 to May 2018, there were numerous instances where renewable inverter-based generating resources performed inadequately after what should have been routine transmission system disturbances such as lighting strikes or trip and reclose situations. Power generation losses in these events varied from a low of 30 MW to a high of 1,200 MW, compounding reliability and resilience concerns.
Why Are ESG Frameworks Important?
