AR 267/2001 s28;85/2004;290/2020;146/2025 Expiry 29 For the purpose of ensuring that this Regulation is reviewed for ongoing relevancy and necessity, with the option that it may be repassed in its present or an amended form following a review, this Regulation expires on June 30, 2030. AR 267/2001 s29;85/2004;31/2014;119/2017;290/2020;146/2025 Coming into force 30 (1) This Regulation comes into force on January 1, 2002. (2) Sections 4, 23 and 25 do not apply before January 1, 2005 to an agricultural operation. Schedule 1 Determination of Minimum Distance Separation Definitions 1 In this Schedule, (a) “dispersion factor” allows for a variance to the MDS due to the unique climatic and topographic influences at the site, and is determined in accordance with section 5; (b) “expansion factor” applies only to expanding operations that are increasing the size of the facility to store more manure, organic materials and compost or to accommodate more livestock, and is determined in accordance with section 6; (c) “exponent” (K) equals 0.365 for all categories or types of livestock and types of material; (d) “Factor A” is the nuisance value of the category or type of livestock determined in accordance with Table 1.1 in the Code; (d.1) “Factor B” is the nuisance value of the category or type of manure or organic materials determined in accordance with Table 1.2 in the Code; (e) “MDS” means minimum distance separation determined in accordance with section 2; (f) “MU” is a manure unit based on the amount of manure produced by a category and type of livestock determined in accordance with Table 1.1 in the Code; (g) “odour objective” means the odour objective determined in accordance with section 4; (h) “odour production” means odour production determined in accordance with section 3; (i) “technology factor” is the effect the handling, collection or storage system will have on reducing the odour nuisance level and is determined in accordance with section 7. Minimum distance separation (MDS) 2 The MDS is measured from the outside walls of neighbouring residences (not property line) to the point closest to manure storage facilities or manure collection areas. The MDS is calculated in metres as follows: (a) for new confined feeding operations or manure storage facilities, MDS = (odour production (total) ) K x odour objective x dispersion factor; (b) for expanding confined feeding operations or manure storage facilities, MDS = (odour production (total) ) K x odour objective x dispersion factor x expansion factor. Odour production 3 Odour production (total) is calculated by the following steps: (a) LSU Factor (type of livestock) = Factor A x technology factor x MU; (a.1) SSU Factor (type of material) = Factor B (type of material) x technology factor; (b) odour production (type of livestock) = LSU factor (type of livestock) x number of animals (type of livestock) ; (b.1) odour production (type of material) = SSU factor (type of material) x number of tonnes (type of material) ; (c) where odour production (total) is calculated for (i) confined feeding operations that have less than 2 years of storage, odour production (total) = sum of odour production from each type of livestock, (ii) confined feeding operations that have more than 2 years of storage, by the following formula: odour production (total) = A + [(B ‑ C) x SSU Factor (type of material) ] where A is the sum of odour production from each type of livestock calculated under subclause (i), B is the tonnes of total storage capacity of the manure storage facility, and C is the manure produced by the operation in 2 years, and (iii) manure storage facilities that are not located at a confined feeding operation, odour production (total) = sum of odour production from each type of material. Odour objective 4 The odour objective factor must be determined according to the category of land zoning and residential type as follows: (a) for Category 1 - residences on land zoned for agricultural purposes (e.g., farmstead, acreage residences), odour objective factor 41.04; (b) for Category 2 - residences on land zoned for non-agricultural purposes (e.g., country residential, rural commercial businesses), odour objective factor 54.72; (c) for Category 3 - residences on land zoned for high use recreational or commercial purposes, odour objective factor 68.40; (d) for Category 4 - residences on land zoned for large‑scale country residential, rural hamlet, village, town or city, odour objective factor 109.44. Dispersion factor 5 (1) Unless information is provided to establish otherwise to an approval officer’s satisfaction, the dispersion factor must equal 1.0. (2) The dispersion factor, if applied, must be determined for the following unique conditions that can influence dispersion: (a) topography factor (D T ), the effect of topographical features on air dispersion; (b) screening factor (D S ), the effect of natural or constructed screening which reduces wind effects at the manure storage facility; (c) micro-climate factor (D W ), the effect of temperature, humidity and wind direction and intensity that demonstrates significant alteration in odour intensity or frequency of occurrence in relation to neighbouring residences. Expansion factor 6 (1) Unless information is provided to establish otherwise to an approval officer’s satisfaction, the expansion factor must equal 1.0.

(2) Despite subsection (1), an approval officer must apply an expansion factor of 0.77 when calculating the minimum distance separation if the confined feeding operation or manure storage facility cannot meet the minimum separation distance without the use of this factor. (3) For the purposes of subsection (2), an approval officer may apply the expansion factor of 0.77 only if 3 or more years have passed since the completion of the most recent construction arising out of an approval, registration or authorization or an amendment of an approval, registration or authorization. Technology factor 7 The technology factor must be determined according to Table 1.1 or 1.2 in the Code unless information is provided to establish otherwise to an approval officer’s satisfaction. New types of livestock 8 An approval officer may determine, within a category of livestock specified in the Schedules to the Agricultural Operations, Part 2 Matters Regulation (AR 257/2001) for an unlisted type of livestock, based on manure production, the relevant factors, units and other measurements required to apply this Regulation to that type.
