Table 3. Non-agricultural source materials odour categories

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
