Decision details

The proposed amendments to the existing Environmental Compliance Approval include the following:

  • increase the approved waste disposal site and waste processing site (anaerobic digestion facility) area from 0.71 hectares (1.75 acres) to 1.07 hectares (2.64 acres).
  • increase the maximum quantity of off-farm anaerobic digestion materials (OFADM) received and processed from 60,000 tonnes or cubic metres per year to 80,000 tonnes or cubic metres per year, for co-digestion with on-farm anaerobic digestion materials.
  • production of 1,075 normal cubic metres per hour (Nm³/h) of biogas.
  • generation of up to 180,000 cubic metres of digestate per year.
  • receipt of up to 80,000 tonnes or cubic metres of OFADM in any 12-month period, with a maximum receipt rate of 400 tonnes or cubic metres per day.
  • pasteurization of feedstocks in four below-grade pasteurization tanks (Tanks 2, 3, 4, and 5) and temporary reception within a below-grade, epoxy-coated concrete reception pit located inside a negatively pressurized receiving building.

How to appealClick to Expand Accordion

Start the process to appeal

If you’re an Ontario resident, you can start the process to appeal this instrument decision.

First, you’ll need to seek leave (i.e. get permission) from the relevant appellate body to appeal the decision.

If the appellate body grants leave, the appeal itself will follow.

Seek leave to appeal

To seek leave to appeal, you need to do these three things:

  1. prepare your application
  2. provide notice to the minister
  3. mail your application to three parties

1. Prepare your application

You’ll need to prepare an application. You may wish to include the following things in your application:

  1. A document that includes:
    • your name, phone number, fax number (if any), and/or email address
    • the ERO number and ministry reference number (located on this page)
    • a statement about whether you are a resident in Ontario
    • your interest in the decision, and any facts you want taken into account in deciding whether you have an interest in the decision
    • the parts of the instrument that you’re challenging
    • whether the decision could result in significant harm to the environment
    • the reason(s) why you believe that no reasonable person – having regard to the relevant law and to any government policies developed to guide decisions of that kind – could have made the decision
    • the grounds (facts) you’ll be using to appeal
    • the outcome you’d like to see
  2. A copy of the instrument (approval, permit, order) that you you are seeking leave to appeal. You’ll find this in the decision notice on the Environmental Registry
  3. Copies of all supporting documents, facts and evidence that you’ll be using to appeal
What is considered

The appeal body will consider the following two questions in deciding whether to grant you leave to appeal:

  1. is there is good reason to believe that no reasonable person, with respect to the relevant law and to any government policies developed to guide decisions of that kind, could have made the decision?
  2. could the decision you wish to appeal result in significant harm to the environment?

2. Provide your notice

You’ll need to provide notice to the Minister of the Environment, Conservation and Parks that you’re seeking leave to appeal.

In your notice, please include a brief description of the:

  • decision that you wish to appeal
  • grounds for granting leave to appeal

You can provide notice by email at minister.mecp@ontario.ca or by mail at:

College Park 5th Floor, 777 Bay St.

3. Mail your application

You’ll need to mail your application that you prepared in step #1 to each of these three parties:

  • appellate body
  • issuing authority (the ministry official who issued the instrument)
  • proponent (the company or individual to whom the instrument was issued)

Proposal details

This proposal is for an amendment to Environmental Compliance Approval No. 1206- BG4SP9 (waste disposal site) for a waste disposal site (processing) for receipt and pre-processing of organic off-farm wastes and processing (anaerobic digestion) of the off-farm wastes with agricultural source materials for production of soil supplements, animal bedding materials, and biogas.

The approval is being sought to expand the existing facility regulated under the Nutrient Management Act consisting of:

  • two solids receiving bunkers and feeders
  • three off-farm waste receiving pits/pasteurizers (holding capacity of 155 cubic metres each)
  • four off-farm waste receiving pits/pasteurizers (holding capacity of 228 cubic metres each)
  • a manure blend tank (holding capacity of 341 cubic metres)
  • a regulated mix anaerobic digester (holding capacity of 5,000 cubic metres)
  • a continuously stirred tank reactor (CSTR) anaerobic digester (holding capacity of 7,000 cubic metres)
  • three generation units
  • biogas conditioning equipment, and
  • two waste gas flares

The digesters and the associated equipment and structures have been built in compliance with all applicable regulatory requirements at the me of construction.

The total area of the proposed waste disposal site is 1.07 hectares. The site will receive a maximum of 400 cubic metres of liquid waste per day or 400 tonnes of non-hazardous solid waste per day with an annual maximum of 80,000 cubic metres of liquid waste or tonnes non-hazardous solid waste. This is an increase of the annual amount of off-farm waste from 60,000 to 80,000 cubic metres/tonnes. The addition of the four off-farm waste receiving pits/pasteurizers of holding capacity of 228 cubic metres for off-farm waste receipt, storage and pre-processing will be used to manage the increased amounts of the off-farm waste. This off-farm waste will then be mixed with the agricultural source materials in the existing secondary mixed anaerobic digester having a 7,000 cubic metres capacity. Generated biogas will be upgraded into renewable natural gas prior to its injection into a natural gas pipeline as well as burned in the three CHP generation units.

The total amount of off-farm waste stored at the site is not to exceed 400 cubic metres or 400 tonnes at any one me. Receiving hours of operation are 7 a.m. to 7 p.m., 6 days a week, and the processing will occur 24 hours a day, 7 days per week. The waste disposal site serves the Province of Ontario.
