Under the authority of sections 3004(a) and 3004(o)(4) of the Resource Conservation and Recovery Act (RCRA), EPA proposed rules requiring new landfills, surface impoundments, waste piles and land treatment units for the treatment, storage or disposal of hazardous waste to utilize an approved leak detection system. EPA also proposed that certain existing land disposal units utilize an approved leak detection system. Additionally, the Agency proposed double liners and leachate collection and removal systems above and between the liners for new waste piles, and replacements and lateral expansions of existing waste piles in parallel with minimum technology requirements for landfills and surface impoundments.You may need a PDF reader to view some of the files on this page.
