Comparison: State vs. Federal
• Rules. Louisiana has established state-specific leak detection requirements that are in addition to the federal requirements. The standards provide a safeguard for preventing spills, releases, and unnecessary contamination. The specific leak detection system standards vary, depending on the type of unit or facility. See the national section LEAK DETECTION for a review of general and federal leak detection requirements.
Landfills and surface impoundments. All new hazardous waste landfills and surface impoundments have to have a leak detection system as part of their liner system. See the state sections LANDFILLS and SURFACE IMPOUNDMENTS for additional guidance.
Hazardous waste storage tanks. A leak detection system on a hazardous waste storage tank is referred to as secondary containment. In addition, to ensure that hazardous waste stored in tanks does not contribute to air pollution, the EPA requires hazardous waste storage tanks to have airtight coverings and vapor control devices. See the state section HAZWASTE STORAGE AND TREATMENT TANKS for additional information.
