Manure Wastewater Storage & Handling What is the purpose of the MWSH part of the CNMP? –Document that the current or planned system is adequate to collect, transfer and store the volume of waste generated until utilization

Manure Wastewater Storage & Handling Collection, storage, treatment, and/or transfer practices shall meet the minimum requirements as addressed in the following NRCS conservation practice standards contained in Section IV of the NRCS FOTG, as appropriate: Waste Storage Facility (Code 313) Waste Treatment Lagoon (Code 359) Manure Transfer (Code 634) Heavy Use Protection Area (Code 561)

Manure Wastewater Storage & Handling Should comply with existing federal, Tribal, State, and local regulations, associated with the following activities: Disposal of dead animals. Disposal of animal medical wastes. Disposal of spoiled feed or other contaminants that may be regulated by a NPDES or State concentrated animal feeding operation (CAFO) permitting program.

Manure Wastewater Handling & Storage The MWSH component should: –Allow for land application plans in conjunction with the producers intention, and available equipment, labor and cropping system in accordance with NRCS Nutrient Management Policy and the conservation practice standard for Nutrient Management (Code 590)

Manure Wastewater Storage & Handling Additional considerations associated with CNMP development and implementation should be addressed. However, NRCS does not have specific technical criteria for these considerations that are required for CNMPs. These considerations are: Air Quality Pathogens

Manure Wastewater Handling & Storage Adequate storage volume should be demonstrated by the CNMP System management requirements to avoid discharge should also be documented

Manure Wastewater Handling & Storage The capacity of the manure storage system should be clearly documented

Manure Wastewater Handling & Storage The Critical Storage Interval Should be Clearly Defined

Storage required for the five month period from November – March = 644,000 gallons Sample Dairy CNMP Critical Storage Interval Storage required for the seven month period from April – October = 598,000 gallons

Manure Wastewater Handling & Storage Component Should Address: Mortality Management System Closure

The MWSH part of the CNMP should document: –Animal numbers –Animal types –Animal weights –Confinement times –Manure production volumes –Nutrient content of wastes –Added wastewater volumes –Bedding volumes – Runoff areas and volumes –Needed treatments

Manure Wastewater Handling & Storage Should Include: Landowners responsibility guide for construction Operation and Maintenance activities for waste system Address Quality Assurance for any new construction Include system drawings and specifications
