A Resource Conservation and Recovery Act (RCRA) permit has been issued by the Kentucky Department for Environmental Protection (KDEP) for the entire footprint of BGAD facility with an Environmental Protection Agency (EPA) ID No. KY8-213-820-105. Bechtel Parsons Blue Grass (BPBG) operates the Blue Grass Chemical Agent-Destruction Pilot Plant (BGCAPP) as a tenant within the BGAD facility. The Program Executive Office, Assembled Chemical Weapons Alternatives (PEO ACWA) is also a tenant operating the Chemical Limited Area hazardous waste management units/igloos within the facility. This public notice includes three permitting actions for permit renewals: one operated by BGAD for the conventional mission; one for continued storage of hazardous and secondary wastes generated during the PEO ACWA igloo closure process; and one for the chemical demilitarization mission operated by BPBG. All three permit renewals are being sought under RCRA. BGAD is the owner for all three permit renewal actions. RCRA regulations require that a permit be renewed every 10 years. BGAD is submitting a RCRA Permit Renewal Request to KDEP for the renewal of permit sections N, D, and P which will allow for the continued management of hazardous waste and secondary wastes that will be generated during the depot conventional mission operations. PEO ACWA is submitting a RCRA Permit Renewal Request to KDEP for the renewal of permit section R which will allow for the continued storage of hazardous waste and secondary waste generated during the igloo closure process. BPBG is submitting a RCRA Permit Renewal Request to KDEP for the renewal of permit sections A, E, and S which will allow continued management of hazardous waste and secondary wastes that will be generated during the Closure phase of the project while decontaminating process equipment and areas. The process equipment and waste storage tanks will no longer be in use and thus will not be included as part of the renewal permit. The BGCAPP facility is currently permitted under a RCRA Part B permit by KDEP.
