2009 Nutrient Management Protocol for Ontario Regulation 267/03 Made under the Nutrient Management Act, 2002

Part 3 - Nutrient Units: Phased In Farm Units Based on Nutrient Units

Farm Units become subject to the Regulation in several ways by building a regulated mixed anaerobic digestion facility, building or expanding milking centre washwater components, land applying NASM or through reaching a threshold number of nutrient units. Using the nutrient units ("NU") concept helps ensure an 'apples to apples' comparison between sizes and types of farm units. Land application requirements for a farm unit, are based on the specific farm unit's NMP, not NUs. NUs are not the same as livestock units, which are used in regimes other than the Nutrient Management Act, 2002, S.O. 2002, and which have been used for the purpose of calculating Minimum Distance Separation setbacks in the previous version of that document.

3.1 Using Nutrient Units to Determine the Obligations of Agricultural Operations Carried Out at a Farm Unit

For agricultural operations with farm animals it is necessary to determine the number of NUs managed on a farm unit. The number of NUs generated on a farm unit by a particular type of farm animal is calculated by dividing the number of farm animals by the number given in the Nutrient Units Column shown on Table 1 Nutrient Unit Livestock Information Table which can be found in the Nutrient Management Tables document.

"Nutrient Management Tables" means the document of that name, as amended from time to time, prepared by the Ministry of Agriculture, Food and Rural Affairs and the Ministry of the Environment for the purposes of the NASM Odour Guide and the Nutrient Management Protocol

If the farm unit has more than one type of farm animal present on it then this calculation would have to be completed for each type of animal separately, then all the results totaled to give the total NU generated by farm animals on the farm.
