Environmental Alert
(by Donald Bluedorn, Gary Steinbauer and Casey Snyder)
On July 29, 2020, United States Environmental Protection Agency (EPA) Administrator Andrew Wheeler signed a pre-publication version of a final rule (the Rule) revising portions of EPA’s 2015 coal combustion residuals (CCR) landfill and impoundment regulations. The Rule becomes final 30 days after publication in the Federal Register.
In 2015, EPA promulgated regulations implementing national minimum criteria for new and existing CCR landfills and surface impoundments. A federal appellate court partially vacated and remanded portions of these regulations on August 21, 2018 (the court’s decision is covered in more detail in our prior Alert). Following the court’s decision, EPA published proposed rules in the Federal Register on December 2, 2019 and August 14, 2019, to address the court’s remand order and make other changes (the Proposed Rules).
The Rule includes the following key changes for CCR units:
- Reclassifies compacted-soil lined or “clay-lined” surface impoundments to “unlined,” meaning these structures must be retrofitted or closed;
- Establishes a revised date, April 11, 2021, by which CCR units must cease receiving waste and initiate closure or retrofit because: (1) they are unlined or were formerly “clay-lined” CCR surface impoundments; or (2) they failed the minimum depth to aquifer location standard;
- Revises the alternative closure provisions that would grant certain facilities additional time to develop alternative capacity to manage their CCR and non-CCR waste streams;
- Updates the annual groundwater monitoring and corrective action report requirements to make the data easier to understand for public review, including adding an executive summary requirement;
