CCR Rule Compliance Data and Information

Background

On April 17, 2015, the U.S. Environmental Protection Agency released the final rule - Hazardous and Solid Waste Management System; Disposal of Coal Combustion Residuals (CCRs) from Electric Utilities - for the management and disposal of CCRs.

Under Subpart D, 40 CFR, Part 257, the new rule establishes minimum national criteria for purposes of determining which solid waste disposal facilities and solid waste management practices do not pose a reasonable probability of adverse effects on health or the environment.

Applicability

Subpart D, Part 257 applies to owners and operators of new and existing landfills and surface impoundments, including lateral expansions of such units that dispose or otherwise engage in solid waste management of CCRs generated from combustion of coal in electric power generation.

This subpart does not apply to CCR landfills that have ceased receiving CCRs or to electric facilities that have ceased producing electricity prior to October 19, 2015. In addition, an inactive CCR surface impoundment that completes closure of such CCR unit no later than April 17, 2018, is exempt from all other requirements of this subpart.

Compliance

Each CCR unit subject to the final rule requirements will record compliance with these requirements in the facility's operating record, notify the state of decisions and maintain this publicly available website of compliance information. These requirements help ensure transparency and provide citizens with the information about our CCR units.
