General requirements for treatment
 98.9 (1) No person shall treat anaerobic digestion materials in a regulated mixed anaerobic digestion facility on a farm unit on which an agricultural operation is carried out except in accordance with the following rules: 1. No anaerobic digestion materials may be treated in the facility unless they are, i. on-farm anaerobic digestion materials that meet the criteria set out in section 98.8, or ii. off-farm anaerobic digestion materials that are received in accordance with sections 98.4, 98.4.1, 98.5, and 98.5.1. 2. Off-farm anaerobic digestion materials that have a dry matter content of less than 1 per cent may be added for treatment in the facility only if the anaerobic digestion materials that are already being treated in the facility have a dry matter content of at least 8 per cent.  The dry matter content of the materials already being treated must be measured during the 24-hour period before the off-farm anaerobic digestion materials are added. 3. At all times at least 50 per cent, by volume, of the total amount of anaerobic digestion materials that are being treated in anaerobic digestion vessels in the facility must be on-farm anaerobic digestion materials. 4. At all times, the total amount of manure being treated in the anaerobic digestion vessels in the facility must be, i. at least 50 per cent, by volume, of the total amount of off-farm anaerobic digestion materials being treated, and ii. at least 5 per cent by volume of the total amount of on-farm and off-farm anaerobic digestion materials being treated. 4.1 Until the requirements set out in paragraphs 3 and 4 are met in a single anaerobic digestion vessel, material may not be removed from an anaerobic digestion vessel, except for treatment in another anaerobic digestion vessel. 5. Subject to subsection (3), the average time anaerobic digestion materials are treated in the facility must be at least 20 days. 6. Subject to subsection (4), anaerobic digestion materials must be treated at no less than 35 degrees Celsius at all times. 7. All the biogas generated by the facility must be collected and treated in accordance with section 98.7. 8. The facility must have a device for monitoring the actual temperature at which the material is being, i. treated, and ii. heated in accordance with subsection (2), if that heating takes place in the facility. 9. The facility must be operated in accordance with a professional engineer’s design specifications. 10. Any sampling port for liquids that is used in respect of the facility, i. must be installed using specifically designed gasketed fittings, such as tees, saddles, end caps and elbows, that are compatible with the material of the sampling port, and ii. must have a primary shut-off valve and a secondary shut-off valve. 11. If the facility is designed to generate biogas at a rate that exceeds 50 m³/hr, it must have a device for monitoring whether the pressure relief device is open. 12. A sign that provides the information set out in subsection (4.1) and can be read from the public road nearest to the facility must be posted on the farm unit. O. Reg. 284/13, s. 13 (1, 2); 508/21, s. 25 (1, 2). (2) Materials listed in Schedule 2 must be heated before or during treatment, (a) for no less than one hour at no less than 70 degrees Celsius; or (b) for no less than 20 hours at no less than 50 degrees Celsius. O. Reg. 284/13, s. 13 (1). (2.1) In the case of materials listed in Schedule 2B, the heating under subsection (2) must take place at the regulated mixed anaerobic digestion facility. O. Reg. 508/21, s. 25 (3). (2.2) In the case of materials listed in Schedule 2B, when the material is introduced into a vessel for the heating required under subsection (2), the material must have a dry matter content of less than 18 per cent and have a slump of more than 150 millimetres using the Test Method for the Determination of Liquid Waste (slump test) set out in Schedule 9 of Regulation 347 of the Revised Regulations of Ontario, 1990 (General — Waste Management) made under the Environmental Protection Act. O. Reg. 508/21, s. 25 (3). (2.3) Despite paragraph 8 of subsection (1), a regulated mixed anaerobic digestion facility that receives more than 10,000 cubic metres of off-farm anaerobic digestion materials in any 12-month period or any material listed in Schedule 2B must have two devices for monitoring the actual temperature at which the materials are being heated in accordance with subsection (2), if that heating takes place in the facility, with those two devices being located separately to ensure the taking of representative temperature measurements. O. Reg. 508/21, s. 25 (3). (2.4) A regulated mixed anaerobic digestion facility that receives more than 10,000 cubic metres of off-farm anaerobic digestion materials in any 12-month period or any materials listed in Schedule 2B must have a means by which a sample can be taken that represents the contents of the anaerobic digestion vessel before the material in the vessel enter into the storage for anaerobic digestion output. O. Reg. 508/21, s. 25 (3). (3) Despite paragraph 5 of subsection (1), anaerobic digestion materials may be treated in the facility for an average time of less than 20 days if, (a) a professional engineer designs the facility such that it is capable of reducing the content of total volatile solids of the materials in the facility by at least 50 per cent in less than 20 days; (b) the facility is built to the engineer’s design specifications; and (c) the average time is equal to or greater than the shorter period of time specified by the professional engineer. O. Reg. 284/13, s. 13 (1). (4) Despite paragraph 6 of subsection (1), anaerobic digestion materials may be treated at less than 35 degrees Celsius if, (a) a professional engineer designs the facility such that it is capable of reducing the content of total volatile solids of the materials in the facility by at least 50 per cent at a temperature that is less than 35 degrees Celsius; (b) the facility is built to the professional engineer’s design specifications; and (c) the anaerobic digestion materials are treated at a temperature that is no less than the temperature specified by the professional engineer. O. Reg. 284/13, s. 13 (1). (4.1) The sign required by paragraph 12 of subsection (1) must, (a) indicate that an anaerobic digestion facility governed by this Regulation is located on the farm unit; and (b) provide the name and contact information of the owner or operator of the facility. O. Reg. 284/13, s. 13 (3). (5) If a nutrient management strategy that contemplates mixed anaerobic digestion in the facility was approved before October 25, 2013, paragraphs 10 and 11 of subsection (1) do not apply to the facility until July 1, 2016.
