BCM1.2 RCRA PERMIT EXCLUSIONSMost of the WWTP components are excluded from the RCRA permitrequirements because they are regulated under the Clean Water Act (CWA)by providing elementary waste water treatment prior to discharge to thePOTW and are contained in tanks [40 CFR 270.1 (c) (2)]. Those componentsthat are contained in tanks are eligible for permit exclusion.OxyChem has determined that the concrete settling basins and the linedlagoons are surface impoundments, not tanks. Therefore, the concretesettling basins and lagoons are not eligible for permit exclusion. Theconcrete settling basins and lined lagoons make up the hazardous wastemanagement facility which must be permitted with a RCRA Part B permit forstoring hazardous waste.1 3 OTHER EXCLUSIONSPlant processes limit the hazardous waste treated at the onsite WWTP tovinyl chloride waste waters (D043) and prevent other hazardous wastesgenerated onsite from entering this waste stream. D043 is a new RCRAhazardous waste for which no Land Disposal Restriction (LDR) treatmentstandard has been established. Therefore, LDRs are not applicable tothis hazardous waste management facility.1.4 OTHER FEDERAL REGULATIONSAt the present time, we believe this facility 1s in compliance with thefollowing federal laws:-TheTheTheTheTheWild and Scenic Rivers ActNational Historic Preservation Act of 1966Endangered Species ActCostal Zone Management ActFish and Wildlife Coordination ActInformation will be provided in accordance with the requirements of 40CFR Part 270.3 at the request of the EPA Region III office.
