The plan must be in effect before accepting any putrescible waste. The storm water run-off plan must be in accordance with planning standards that achieve local, state and federal water-quality criteria. This runoff plan can contain one or more component "best management practices" which are part of the overall plan.

C. The applicant demonstrates knowledge and capability to conduct the agricultural composting operation in compliance with the regulations and to produce a stabilized compost product.

Wood containing or likely to contain asbestos, glues, or chemical preservatives such as creosote, pentachlorophenol, paints, stains or other coatings shall not be considered wood wastes under these Rules and Regulations and are prohibited from being processed. An agricultural unit which processes the woods described in this Rule shall not be considered to be conducting agricultural composting and shall be subject to Part 140-05-8 of this Title, Solid Waste Regulation No. 8.

The Division of Agriculture may revoke or suspend a registration for failure to comply with Rules and Regulations of the Department of Environmental Management.

If any provision of these Rules and Regulations, or the application thereof to any person or circumstances, is held invalid by a court or competent jurisdiction, the validity of the remainder of the Rules and Regulations shall not be affected thereby.
