Design Requirements for Ash Landfills

(1) Applicability. In addition to the regulations set forth in 310 CMR 19.100 et seq., 310 CMR 19.119 shall apply to all new landfills or upgrades and expansions of existing landfills, or parts thereof, in which ash and/or residues from solid waste combustion facilities burning municipal solid wastes are disposed. For the purposes of 310 CMR 19.000, such facilities shall be termed "ash landfills". (2) Plans for Ash Landfills. Plans for ash landfills shall include all components and be submitted in accordance with the requirements of 310 CMR 19.104. In addition to the submittal requirements specified in 310 CMR 19.104, the plans for an ash landfill shall include: (a) a discussion of how ash will be transported to and handled at the landfill, including any ash stabilization procedures; and (b) a description of the means by which fugitive emissions of ash will be controlled. (3) Ash Landfill Design. (a) Ash landfills shall incorporate the design requirements for landfills set forth at 310 CMR 19.110 through 19.118, including ground water protection systems and final cover systems, except that ash landfills that will not co-dispose MSW and are not located on top of existing solid waste landfills may not be required to comply with 310 CMR 19.112(5) and 19.117 for installation of a gas collection system. (b) Ash landfills shall be designed to ensure that: 1. the ash is underlain by a ground water protection system meeting the performance and design standards for liners set forth in 310 CMR 19.110. Where an ash landfill expansion is proposed over a previously landfilled area with an existing liner, a ground water protection system in accordance with 310 CMR 19.111: Alternative Ground Water Protection System Design, shall be required; and 2. fugitive emissions of ash are minimized.
