What is it:
A waste storage impoundment made by constructing an embankment and/or excavating a pit or dugout or by fabricating a manmade structure. Waste storage facility is to store or settle agricultural by-products in order to maximize their use as soil amendments in an environmentally safe manner. Waste treatment lagoon is an impoundment made by excavation or earth fill for biological treatment of animal or other agricultural waste.
Where is it used:
Waste Storage Facility applies where
- The storage and/or settling facility is a component of a conservation plan and Comprehensive Nutrient Management Plan (CNMP), and shall be compatible with other components of the conservation plan and CNMP.
- The facility’s function is to store or settle organic by-products generated by agricultural production or processing.
- Also refer to NRCS Ohio Practice Standard 359 “Waste Treatment Lagoon” treatment of organic waste.
- The storage or settling facility can be constructed, operated, and maintained in an environmentally safe manner, protecting our natural resources such as soil, water, air, plants, and animals.
- The soils, geology, and topography are suitable for construction of the facility.
Earthen facilities only apply to embankments where:
- The total height of the dam is 25 ft or less and the storage volume is 50 acre-ft or less. Total height is the vertical measurement from the low point on the downstream toe to the top of the dam.
- Damage resulting from failure would be limited to farm buildings, agricultural land, and township or country roads.
Covered manure storage facilities – This practice standard applies to covers integrated as part of a structural concrete tank. Otherwise, practice standard 367- Roofs and Covers, applies to rigid, semi-
rigid, and flexible manure storage covers associated with facilities designed under 313.
Waste Treatment Lagoon is to biologically treat organic waste efficiently and effectively so as:
to reduce odor
to reduce surface and ground water contaminants;
to liquefy organic waste and reduce the nutrient content of the effluent.
