(A) All CDDLs shall have the permanent stormwater diversion system in place down gradient of the waste cell footprint before CDD disposal can commence. Construction of temporary ditches to divert stormwater to the permanent system during construction is required.
(B) Stormwater diversion systems will be designed to reduce leachate production during construction of the CDDL, divert all stormwater around and away from the CDDL, divert stream flows and to protect the CDDL from erosion.
(C) The permanent system must have the design capacity to handle a 25-year storm event and be hydrologically connected to a surface water feature (i.e., ditch, stream, pond and the like).
(D) At minimum, the permanent system shall consist of a two-foot wide ditch or swale that extends around the perimeter of the CDDL. The permanent conveyance structure shall be lined with a minimum of six inches of rip-rap or geo-textile fabrics.
(E) The Solid Waste Coordinator shall maintain the right to require additional stormwater diversion structures or facilities at his or her discretion in order to protect the CDDL from erosion or to reduce leachate production. This includes, but is not limited to, requiring the installation of scour-holes, berms, revetments, headwalls and detention ponds.
