(A) Conveyance system.
(1) All CDDLs shall have a leachate collection system in place prior to CDD disposal.
(2) At minimum, a leachate collection system shall consist of a toe-drain and a single interior collection line. The interior collection pipe will be, at minimum, an eight inch diameter perforated pipe, surrounded by two feet of crushed rock.
(3) The toe-drain will be constructed along the down gradient side of the CDDL.
(4) Extension of the toe-drain collection system around the perimeter of the CDDL or the construction of additional interior collection lines may be required if the shape of the CDDL or other site conditions is such that total leachate collection is uncertain. The Solid Waste Coordinator will maintain the right to require additional improvements at his or her discretion to ensure that leachate is collected.
(5) Staging of lateral line construction or activation in order to capture leachate from an active filling area and to avoid collecting stormwater that has not come in contact with CDD is permissible.
(B) Collection tank.
(1) All leachate collected by the leachate conveyance system must be discharged to the leachate collection tank.
(2) The tank may be made of fiberglass, steel or pre-casted concrete. A single tank or multiple tanks may be used; however, the total tank capacity shall be a minimum of 2,000 gallons.
(3) The construction of the tank may be similar to that used in standard septic system designs.
(4) The design of the tank must be such that standard laboratory sampling devices, such as bailers, can be employed to extract sufficient quantities of the leachate for testing.
(5) All pipe entrances to the tank must be sealed to be watertight.
(6) The top manhole port used to evacuate the internal product must be a minimum of ten inches in diameter and exposed for easy access.
(7) Any tools necessary for the removal of the port lid must be present on site at all times until closure of the CDDL.
