Manure Management Planning Resources
In Pennsylvania, all agricultural operations that land-apply manure or agricultural process wastewater, regardless of size, are required to have and implement a written plan to manage nutrients and protect water quality. Additionally, this requirement includes agricultural operations that manage Animal Concentration Areas and/or pastures. For operations that are not classified as a Concentrated Animal Feeding Operation (CAFO) or as a Concentrated Animal Operation (CAO), a Manure Management Plan (MMP) will meet this regulatory requirement.
What Is a Manure Management Plan?
A Manure Management Plan (MMP) is a written, site‑specific document that outlines how manure and agricultural process wastewater will be collected, stored, handled, and applied on an agricultural operation. Manure Management Plans are regulated by the Pennsylvania Clean Streams Law and 25 PA Code Chapter 91.36(b). Supporting guidance for the regulations is provided in the Pennsylvania Department of Environmental Protection's Land Application of Manure: A Supplement to Manure Management for Environmental Protection.
The Pennsylvania Department of Environmental Protection (PA DEP) provides two standard planning templates:
- Manure Management Plan Short Form
- Manure Management Plan Workbook
PA DEP also accepts three alternative formats:
- PAOneStop Manure Management Plan Module
- NRCS 590 CNMP
- Act 38 NMP
The MMP Short Form is an option for agricultural operations that meet specific eligibility criteria described in the PA DEP's Land Application of Manure Manual. Agricultural operations that cannot continuously meet the MMP Short Form criteria must develop a plan using the full MMP Workbook or an approved alternative format accepted by PA DEP.
Why Are Manure Management Plans Important?
A Manure Management Plan (MMP) can help an agricultural operation not only comply with state regulations but also protect water quality by reducing nutrient losses to environmentally sensitive areas. Additionally, an MMP can strengthen agricultural operations by identifying practices and strategies that could improve soil health, increase crop productivity, and reduce fertilizer costs. Finally, a thorough and up-to-date MMP can support on-farm decision-making by providing a centralized location for an operation’s management records.
Who Can Write a Manure Management Plan and What Information is Required?
Manure Management Plans can be prepared by any individual with knowledge about the agricultural operation, including the operator. However, assistance from trained and experienced professionals will be beneficial and, at times, necessary when developing an MMP. Assistance may be available from a variety of sources, including certified nutrient management specialists, certified manure brokers and haulers, county conservation districts, USDA Natural Resource Conservation Service (USDA-NRCS) staff, Pennsylvania State University staff, and agricultural organizations.
To develop an acceptable and effective MMP, the plan writer will need detailed and up-to-date information about the operation, including the following:
- Animals: types, numbers, average weights, and days on operation
- Crops: crop types, expected and actual yields, fields, rotations, and fertilizer application rates
- Landscape Features: field names, operation and field boundaries, cropland and pasture acres, and environmentally sensitive areas
- Manure Management: spreader calibration, calculated application rates, manure types, application timing, and manure setbacks
- Manure and Agricultural Process Wastewater Storage and Stacking: storage type, storage and stacking specifications, location, construction, and condition
- Pasture and Animal Concentration Areas (ACAs): locations, size, management, and conditions
- Best Management Practices (BMPs): implementation dates, locations, numbers, and size.
Manure Management Plan Key Terms
Agricultural Process Wastewater - wastewater from agricultural operations, including from spillage or overflow from livestock or poultry watering systems, washing, cleaning, or flushing pens, milkhouses, barns, manure pits, direct contact swimming, washing, or pray cooling of livestock or poultry, egg washing, or dust control.
Animal Concentration Areas (ACAs) - animal confinement areas that will not maintain a growing crop (e.g., barnyards, loafing areas, or exercise lots). Animal access ways, feeding areas, watering areas, and shade areas or walkways are not considered ACAs if they do not cause a direct flow of manure-contaminated runoff to surface waters, sinkholes, or springs.
Best Management Practices - Activities, facilities, measures, planning or procedures that are effective and practicable to manage nutrients to protect, maintain, reclaim, and restore the quality of water and existing and designated uses of surface and ground water.
Pastures - Land used for grazing animals that is managed under a grazing plan meeting the requirements of the Natural Resources Conservation Service Pennsylvania Technical Guide Practice Standard 528 for Prescribed Grazing; OR to maintain at least three inches of vegetation height and 70% perennial vegetative cover.
