SOLID WASTE PROCESSING AND DISPOSAL
Rule 1200-01-07-.04, continued)
The volume and physical and chemical characteristics of the leachate.
A leachate collection and removal system is required immediately above the liner that is designed, constructed, maintained, and operated to collect and remove leachate from the facility. The leachate collection and removal system must be:
Constructed of materials that are:
Chemically resistant to the waste managed in the facility and the leachate expected to be generated; and
Of sufficient strength and thickness to prevent collapse under the pressures exerted by overlying wastes, waste cover materials, and by any equipment used at the facility. Other equivalent or superior protection may be substituted for this buffer as approved by the Commissioner.
Protected, by design and/or operational features, from equipment mishandling that might reasonably be expected during operation.
Such facilities must be designed, constructed, operated, and maintained such that the final cover includes a cap which will:
Provide long-term minimization of migration of liquids through the closed facility;
Function with minimum maintenance;
Accommodate settling and subsidence so that the cap’s integrity is
Meet the closure requirements of paragraph (8) of this rule.
The leachate collection and removal system must, at a minimum, meet the
constructed, operated, and maintained such that the leachate depth over the liner does not exceed one foot as calculated referencing the infiltration volume of the 25-year 24-hour storm through the intermediate cover.
Leachate interception surfaces and associated piping must be designed, constructed, operated, and maintained to function without clogging throughout the scheduled post-closure care period;
Leachate collection reservoirs must:
Be constructed (e.g., lined) such that collected leachate is contained;
Have sufficient capacity to store the volume of leachate expected to
be generated in 30 days, or other adequate provisions approved by the Commissioner; and
