Summary

The EPA's Final Coal Combustion Residual (CCR) Rule was published on April 17, 2015 and went into effect on October 19, 2015. The rule regulates existing active CCR waste landfills and surface impoundments (ponds) and all new CCR waste disposal units built after the rule's publication. The rule also regulates inactive surface impoundments that contain CCRs and water after the rule's effective date. Tampa Electric's Big Bend Station has existing onsite CCR surface impoundments regulated under the rule. The company is required to perform groundwater monitoring, formulate operating plans for its regulated CCR units and to post the resulting reports and other documents on this website.
