Comparison: State vs. Federal
• Rules. Arkansas generally follows the U.S. Environmental Protection Agency's federal leak detection rules, with additional requirements for facilities storing liquid animal waste from confined animal operations. Subsurface investigation is required to measure any liner leakage from holding ponds and treatment lagoons. See the state sections AG WASTE and GROUNDWATER for more information.
In addition to federal rules, landfills must maintain additional records related to landfill liners, leachate collection systems, and groundwater monitoring systems. See the state section SOLID WASTE for more information.
Arkansas follows federal rules for hazardous waste tank systems, surface impoundments, landfills, and waste piles. See the national section LEAK DETECTION for more information, and consult facility permits for any site-specific leak detection design and monitoring requirements.
Arkansas has also adopted the federal secondary containment requirements under the federal Underground Storage Tank Compliance Act (USTCA). See the state section UNDERGROUND STORAGE TANKS for more information.
