NPDES Permit BMP and SPCC Plans

The KPDES general coal permit states, “The permittee shall develop and implement a BMPP consistent with 401 KAR 5:065, Section 2(4) pursuant to KRS 224.70-110, which prevents or minimizes the potential for the release of “BMP pollutants” from ancillary activities through site runoff; spillage or leaks, sludge or waste disposal; or drainage from raw material storage. These conditions apply to all permittees who use, manufacture, store, handle, or discharge any pollutant listed as: (1) toxic under Section 307(a)(1) of the Clean Water Act; (2) oil, as defined in Section 311(a)(1) of the Act; (3) any pollutant listed as hazardous under Section 311 of the Act; or (4) is defined as a pollutant pursuant to KRS 224. 1-010(35) and who have operations which could result in (1) the release of a hazardous substance, pollutant, or contaminant, or (2) an environmental emergency, as defined in KRS 224.1-400, as amended, or any regulation promulgated pursuant thereto (hereinafter, the “BMP pollutants”). These operations include material storage areas; Plant site runoff; in-Plant transfer, process and material handling areas; loading and unloading operations, and sludge and waste disposal areas. The permittee shall implement the BMP Plan upon of the commencement of regulated activity. Modifications to the Plan as a result of ineffectiveness or Plan changes to the facility shall be implemented as soon as possible. Within 90 days of the effective date of the permit, the permittee shall evaluate the current BMP Plan and make any necessary modifications to insure its continued effectiveness.
