Table 3. Non-agricultural source materials odour categories
Table 3 is used to classify non-agricultural source materials for land application. This technical information is for Ontario producers.
Introduction
Non-agricultural source materials (NASM) are classified under one of three categories.
The NASM in each of the categories can be applied to agricultural land.
On-farm storage and land application standards vary based on the category and other characteristics of the NASM (for example, solids content, odour potential, metal levels and pathogen content).
The information in Table 3 is presented in a list format.
Odour category 1 (OC1)
NASM less than 500 odour units:
- Leaf and yard waste, including leaf and yard waste that has been composted but does not meet the requirements for Category AA or A compost in Part II of the Compost Standards or the criteria in subsection 1(1.1) of this regulation.
- Washwater, including materials containing food-grade cleaners, from cleaning the equipment and processing area of:
- a bakery
- a confectionery processing facility
- a cereal and grain processing facility
- a snack food manufacturing facility
- a brewery or distillery
- Fruit and vegetable processing water that contains no chemicals other than food-grade chemicals
- Liquid anaerobically digested sewage biosolids from a municipal sewage treatment plant or its off-site storage facility
- Compost that meets the requirements for Category B compost in Part II of the Compost Standards
- Manure from non-farm herbivorous animals, including associated bedding materials
- Runoff from animal yards that are used only by non-farm herbivorous animals
- Runoff from permanent nutrient storage facilities containing only manure from non-farm herbivorous animals, including associated bedding materials
- Washwaters from a building or structure, or part of a building or structure, that houses only non-farm herbivorous animals
Odour category 2 (OC2)
NASM that are equal to or greater than 500 odour units but less than 1,500 odour units:
- Culled fruit and vegetables, including cole crops and onions that have been processed
- Peels and pomace produced from fruits and vegetables, including cole crops and onions
- Organic waste matter that contains no meat or fish and is derived from food processing at:
- a bakery
- a confectionery processing facility
- a cereal and grain processing facility
- a snack food manufacturing facility
- a brewery or distillery
- Washwater, including materials containing food-grade cleaners, from cleaning the equipment and processing area of a fish processing facility
- Cooked pet food manufacturing waste
- Pulp and paper biosolids that are primary or combined solids
- Liquid aerobically digested sewage biosolids from a municipal sewage treatment plant or its off-site storage facility
- Washwater, including materials containing food-grade cleaners, from cleaning the equipment and processing area of a facility for processing:
- meat
- eggs
- dairy products
- Paunch manure
- Organic waste matter derived from the production of biodiesel
- Sewage biosolids which have been dewatered by means other than a centrifuge operated at more than 2,000 revolutions per minute (rpm) and stored less than 30 days after dewatering is completed
footnote 1
Odour category 3 (OC3)
NASM that are equal to or greater than 1,500 odour units but less than 4,500 odour units:
- Organic waste matter from grease traps and interceptors
- Organic waste matter produced in a dissolved air flotation process used for the treatment of wastewater from food and feed processing or preparation facilities
- Waste products from animal feeds listed in Classes 1, 2, 3, 4 and 5 of Part 1 of Schedule IV to the Feeds Regulations, 1983 (SOR/83-593) made under the Feeds Act, 1985 (Canada) that may contain an animal product
- Organic waste matter from the processing of fish
- Sewage biosolids which have been dewatered by a centrifuge operated at 2,000 or higher rpm
- Sewage biosolids which have been dewatered and stored for 30 days or more after the dewatering process is completed
Footnotes
- footnote[1] Back to paragraph It is recognized that the rpm of centrifuge is not the only contributing factor to odour. Centrifuges operated to produce high shear forces will produce more odourous cake.
