- (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.
