CCR Rule Compliance Data and Information


Southern Indiana Gas and Electric Company (SIGECO) has established this site for the purpose of posting documentation as required in the EPA's Coal Combustion Residuals rule at 40 CFR Parts 257.105 - 257.107. Beginning on the October 19th, 2015 effective date of the rule, documents will be placed in the operating record as required and subsequently posted to this page within 30 days, or as otherwise required per the compliance deadlines listed in the rule. SIGECO has two generating facilities that are covered by the CCR rule. Information for each site will be listed separately. Please send any inquiries to CCR_Inquiries@centerpointenergy.com​​.


​A.B. Brown Ash​ Pond Closure

The A.B. Brown Ash Pond no longer receives coal combustion materials. A closure plan has been submitted to the Indiana Department of Environmental Management (IDEM). A copy of the initial submitted closure plan is available on this website here A.B Brown Closure Plan_IDEM_11-13-23​ (PDF).

F.B. Culley West Ash Pond Closure

The F.B. Culley West Ash Pond no longer receives coal combustion materials, and has completed closure under the requirements of the Coal Combustion Residuals rule and the Approval of Closure/Post-Closure Plan from IDEM. More information on this project is available at the Indiana Department of Environmental Management Virtual File Cabinet (SW Program ID 87-UP-14).​
