8 CAR § 60-427. Surface water control

(a) Applicability. Each landfill shall design and implement a system to control surface water at the facility in accordance with the minimum standards set forth in this section. (b) Surface water control requirements. (1) Design of permanent and temporary drainage and runoff facilities and structures shall be documented in the operating or design narrative. (2) Unless approved by the Division of Environmental Quality, each facility shall be designed with a positive means of runoff and sedimentation control such as a sedimentation pond through which runoff from disturbed areas is routed. (3) Runoff from active portions of the working face that has contacted the waste shall be considered leachate and shall be managed accordingly. (c) Sedimentation pond discharges. (1) Sedimentation pond discharges shall be permitted as required by the division. (2) Copies of discharge permits and monitoring reports shall be retained on site and be available to the division for inspection. (d) Erosion control. (1) The design shall also include berms, swales, benches, downchutes and other measures as appropriate on steep slopes to minimize erosion. (2) In areas where flow quantity and velocity warrant, rip rap, gabions, revetments, or other protection shall be provided. (e) Active portion runoff. (1) The design narrative shall describe methods that the facility will use to minimize and control runoff from active portions of the landfill. (2) The narrative shall also describe methods that the facility will utilize to segregate contaminated from uncontaminated runoff during fill activity. (f) Final and interim slope stabilization. (1)(A) The operating narrative shall describe seeding and soil stabilization methods on both interim and final slopes. (B) In general, exposed slopes shall be seeded or stabilized if it is anticipated that these slopes will not be disturbed for more than one (1) growing season. (C) More frequent seeding or stabilization may be required to prevent erosion of the cover system. (2) The narrative shall also describe vegetative maintenance procedures and shall provide that vegetation shall be maintained in such a manner that vigorous growth is achieved. (g) Use of fertilizers, pesticides, herbicides, etc. The use of fertilizers, soil mixtures, pesticides, and herbicides shall be controlled to prevent pollution of surface and ground water.
