DECISION DELIVERED BY HUGH S. WILKINS AND ORDER OF THE TRIBUNAL
1On October 2, 2020, the Director, Ministry of the Environment, Conservation and Parks issued Amended Environmental Compliance Approval No. 5238-BSVRHU (“ECA”) relating to Darling International Canada Inc.’s (“Appellant”) Rothsay Moorefield Plant (“Facility”) located in the Township of Mapleton. The Facility is an animal by-product collection, processing and feed ingredient manufacturing plant. The Appellant appealed specific conditions imposed under the ECA, including conditions regarding the ECA’s use of odour unit limits.
2On April 30, 2021, the Tribunal held a Case Management Conference (“CMC”) at which the Parties discussed the preparation of an Issues List and draft Procedural Order, discussed opportunities for settlement discussions, and requested the setting of hearing dates.
3Subsequent to the CMC, the Parties informed the Tribunal that they had not come to agreement on the Issues List. On June 4, 9, and 10, 2021, they provided written submissions on the appropriateness of proposed issues.
4Also, on May 19, 2021 and July 7, 2021, the Parties provided joint submissions, on consent, requesting that the Tribunal amend the ECA to extend the due date in the ECA’s Condition 1.1 for implementation of required odour limits.
5Each of these items is addressed below.
Preparation of a draft Procedural Order and Issues List
6At the CMC, the Appellant identified its proposed issues for the hearing. The Tribunal directed the Parties to prepare and file an Issues List and draft Procedural Order setting out the issues to be adjudicated, due dates for the exchange of documents, and other procedural aspects for the hearing. Subsequent to the CMC, the Parties informed the Tribunal that they were unable to agree on an Issues List. Through the Tribunal’s Case Coordinator, the Tribunal directed them to file written submissions on the proposed issues. The final submissions were received on June 10, 2021.
7The issues in dispute are Issue Nos. 5, 6, 9 and 11 as set out in the Issues List filed with the Tribunal by the Director on June 10, 2021. The Appellant argues that it is necessary that issues regarding the appropriateness of using certain odour concentration measurements as legal compliance and enforcement mechanisms, the effects of updates to atmospheric dispersion models, associated meteorological data files and terrain elevation files, and variations in perception of odour must first be determined before assessing the appropriateness of the ECA’s provisions. The Director submits that the Appellant’s wording for each of these proposed issues addresses matters that are beyond the Tribunal’s jurisdiction to adjudicate. The Director submits that each issue should specifically address the instrument under appeal and the Tribunal cannot make declarations regarding measurements, models or human perception in general.
8The Appellant’s proposed Issue No. 5 is:
- Does the measurement of odour concentration, expressed in Odour Units, following European Standard EN13725: 2003, as required by the Ontario Source Test Code, Part G - Method ON-6: Determination of Odour Emissions from Stationary Sources, have the established scientific basis, accuracy, and precision needed to be:
a. a legal compliance and enforcement mechanism, and
b. a limit in Darling International Moorefield’s ECA?
9The Director proposes that Issue No. 5 should read:
- Does the measurement of odour concentration, expressed in Odour Units, following European Standard EN13725: 2003, as required by the Ontario Source Test Code, Part G - Method ON-6: Determination of Odour Emissions from Stationary Sources, have the established scientific basis, accuracy, and precision needed to be a legal limit in Darling International Moorefield’s ECA?
10The Appellant’s proposed Issue No. 6 is:
- Is there certainty or uncertainty associated with odour concentration measurements of environmental samples following EN13725: 2003, and is that level of certainty or uncertainty, combined with changes associated with dispersion modelling, appropriate as:
a. a legal compliance and enforcement mechanism, and
b. a limit in Darling International Moorefield’s ECA?
11The Director proposes that Issue No. 6 should read:
- Is there certainty or uncertainty associated with odour concentration measurements of environmental samples following EN13725: 2003, and is that level of certainty or uncertainty, combined with changes associated with dispersion modelling, appropriate for a legal limit in Darling International Moorefield’s ECA?
12The Appellant’s proposed Issue No. 9 is:
- Do periodic updates to approved atmospheric dispersion models, associated meteorological data files and terrain elevation files affect predicted odour concentration and compliance or non-compliance with an Odour Performance Limit? If yes, how and in what circumstances? If yes, what effect, if any, does this have on Darling International’s predicted odour concentration and compliance or non-compliance with the Odour Performance Limit in Darling International’s Approval?
13The Director proposes that Issue No. 9 should read:
- Do periodic updates to approved atmospheric dispersion models, associated meteorological data files and terrain elevation files affect Darling International Moorefield’s predicted odour concentration and compliance or non-compliance with an Odour Performance Limit? If yes, how and in what circumstances?
14The Appellant’s proposed Issue No. 11 is:
- Does an Odour Performance Limit measured in Odour Units take into account physiological factors associated with odour, the ability of humans to identify odour, variation in human odour perception, variation of human perception of n butanol, and whether the human experience of odour is or is not highly subjective? If yes, how and in what circumstances? And, how do these variations impact Darling International’s compliance or non-compliance with the Odour Performance Limit in Darling International Moorefield’s EPA, s. 9 Approval?
15The Director submits that Issue No. 11 should be deleted.
Findings
16An Issues List is intended to set out the issues to be adjudicated by the Tribunal. It should be specific enough so that each party is made aware of all the issues to be addressed and can properly prepare for the hearing and call the necessary evidence. The issues should only include questions that need to be adjudicated and that are within the Tribunal’s authority to address. The issues to be adjudicated must be triable and capable of adjudication. Background facts and evidence are not issues. Concerns or questions seeking the Tribunal to make a general declaration on a subject are neither within the Tribunal’s mandate nor are they necessary for the Tribunal to adjudicate an appeal.
17In the present case, the Tribunal finds that general issues that the Appellant seeks to have the Tribunal address may be matters on which the Tribunal may receive background evidence, however, the focus of the Tribunal’s decision must be on the ECA and the specifics at the facility in question. Evidence and submissions providing background and context on methodologies, modelling, and applicable science may be of assistance to the Tribunal in adjudicating the appeal, but the Tribunal does not have the authority to make general declarations regarding them. The Tribunal finds that the language proposed by the Director focuses on the ECA and the Facility and is appropriate wording for Issue Nos. 5, 6, and 9 (as set out in paragraphs 9, 11, and 13 above). The Tribunal finds that answers to the questions raised in Issue No. 11 may be relevant as background evidence, but the focus of the issue for adjudication must be on the ECA and the Facility. The Tribunal finds that the following abridged language for Issue No. 11 is appropriate:
- How do variations in odour perception, if any, impact Darling International’s compliance or non-compliance with the Odour Performance Limit in Darling International Moorefield’s EPA, s. 9 Approval?
The Tribunal approves the Issues List and a draft Procedural Order with the wording for the Issues proposed by the Director for Issue Nos. 5, 6, and 9 and as revised by the Tribunal for Issue No. 11.
Opportunities for Settlement Discussions
18At the CMC, the Parties stated that they have engaged in settlement discussions, but have been unable to reach an agreement. The Appellant stated that given the nature of the dispute, it does not believe that the case is amenable to mediation. The Tribunal urged the Parties to continue settlement discussions.
Scheduling of the Hearing
19At the CMC, the Parties identified the types of witnesses that they intend to call and the time required for a hearing. The Tribunal scheduled a three-week hearing commencing on April 4, 2022.
Proposed Amendment to the ECA’s Due Dates
20On May 19, 2021 and July 7, 2021, the Parties submitted a written request and submissions to the Tribunal seeking to extend the due date in the ECA’s Condition 1.1 on implementation of the required odour limits. Condition 1.1 states:
Performance Conditions
By April 1, 2022, the maximum 10-minute average concentration of odour at a Sensitive Receptor, resulting from the operation of the Facility, including fugitive emissions, shall not be greater than the Odour Performance Limit.
21The Parties submit that with the hearing scheduled to commence on April 4, 2022, a decision on the appeal will not be made until after the April 1, 2022 due date has passed. The Parties request, on consent, to having the due date extended to October 1, 2022. In their submissions, the Parties state that the Appellant is continuing to make efforts to reduce odour emissions and to consult with the community. They submit that the proposed extension would not cause harm to the environment and would streamline the proceeding by avoiding the need for a stay motion hearing. Based on these submissions, the Tribunal finds that the requested amendment is consistent with the purpose and provisions of the Environmental Protection Act and is in the public interest. Given the scheduling of the hearing for April 2022 and the consent of the Parties, the Tribunal approves the requested amendment to the ECA.
Other Items – Site Visit Request
22At the CMC, the Appellant requested that a site visit be ordered. The Tribunal defers this request to the Panel hearing the appeal.
ORDER
23The Tribunal approves the draft Procedural Order and Issues List appended as Schedule 1 to this Order and Decision.
24The Tribunal orders that Condition 1.1 of the ECA is amended so that it now states:
Performance Conditions
By October 1, 2022, the maximum 10-minute average concentration of odour at a Sensitive Receptor, resulting from the operation of the Facility, including fugitive emissions, shall not be greater than the Odour Performance Limit.
25The Tribunal orders that the hearing of the appeal will commence by video on Monday, April 4, 2022 at 10 a.m. Fifteen days have been set aside for the hearing.
26The Case Coordinator will provide the call-in details.

Attachment 2 – Issues List of Darling
Issue 1: Odour Performance Limit at Sensitive Receptors (ECA Condition 1.1)
Did the operational changes made by Darling International reduce odour impacts in the community? Have these operational changes helped to reduce predicted odour concentrations in the community?
Have the odour control investments made by Darling International Moorefield helped to reduce odour impacts in the community? Have these investments helped to reduce predicted odour concentrations in the community?
Can Darling International Moorefield’s rendering operations consistently and/or feasibly achieve the 1.0 Odour Unit Odour Performance Limit as set out in Darling International Moorefield’s EPA, s. 9 Approval?
Are there environmental benefits and environmental disbenefits if Darling International Moorefield’s rendering plant operations are interrupted, curtailed or cease, or if the plant operates in non-compliance with a 1.0 Odour Unit Odour Performance Limit in Darling International Moorefield’s EPA, s. 9 Approval?
Does the measurement of odour concentration, expressed in Odour Units, following European Standard EN13725: 2003, as required by the Ontario Source Test Code, Part G - Method ON-6: Determination of Odour Emissions from Stationary Sources, have the established scientific basis, accuracy, and precision needed to be a legal limit in Darling International Moorefield’s ECA?
Is there certainty or uncertainty associated with odour concentration measurements of environmental samples following EN13725: 2003, and is that level of certainty or uncertainty, combined with changes associated with dispersion modelling, appropriate for a legal limit in Darling International Moorefield’s ECA?
Does any exceedance of that same laboratory-derived 1.0 Odour Unit serve as a predictor of any potential adverse effect in the community nearest Darling International Moorefield’s rendering plant? Does any exceedance of that same laboratory-derived 1.0 Odour Unit give rise to a breach of Darling International Moorefield’s EPA, s. 9 Approval?
Have historical odour concentrations at sensitive receptors near the Darling International Moorefield rendering plant been shown to correlate with there being any potential adverse effects from Darling International Moorefield’s rendering plant? Does the correlation demonstrate that achieving an Odour Performance Limit of 1.0 Odour Unit reduces or eliminates any potential adverse effects from Darling International Moorefield rendering plant?
Do periodic updates to approved atmospheric dispersion models, associated meteorological data files and terrain elevation files affect Darling International Moorefield’s predicted odour concentration and compliance or non-compliance with an Odour Performance Limit? If yes, how and in what circumstances?
Is there accurate, verified, and complete information about odour complaints that justifies the inclusion of an Odour Performance Limit in Darling International Moorefield’s Approval?
How do variations in odour perception, if any, impact Darling International’s compliance or non-compliance with the Odour Performance Limit in Darling International Moorefield’s EPA, s. 9 Approval?
Does the incorporation of an Odour Performance Limit expressed in Odour Units in Darling International Moorefield’s EPA, s. 9 Approval strike a fair and reasonable balance between the interests of Darling International Moorefield’s operation of a rendering plant in Moorefield and the protection of the environment?
Is an Odour Performance Limit, expressed in Odour Units, an appropriate, reliable and certain legal compliance and enforcement mechanism for incorporation into Darling International Moorefield’s EPA, s. 9 Approval?
Should the Darling International Moorefield’s EPA, s. 9 Approval include an Odour Performance Limit at sensitive receptors?
a. If yes, should that limit be 1.0 Odour Unit or a limit other than 1.0 Odour Unit?
b. If yes, by which date should the ECA require compliance with that limit?
c. If no, is there an appropriate alternative to regulating odour from Darling International Moorefield’s rendering plant?
- Or, as an alternative, is there utility, practicality and fairness associated with incorporating an Odour Abatement Plan requirement into Darling International Moorefield’s EPA, s. 9 Approval?
Issue 2: Odour Removal Efficiencies in Biological Oxidation System (ECA Condition 5.8(e))
Should Darling International Moorefield’s EPA, s. 9 Approval require Darling International Moorefield to quantify and report the odour removal efficiencies of the biological oxidation system (Condition 5.8(e))?
Is the measurement of biofilter odour removal efficiency a relevant and representative metric for Darling International Moorefield’s ECA when what is relevant is the quality of odour emissions emanating from the biofilter, and practical efforts to mitigate odour impacts to nearby sensitive receptors?
Is it reasonable and fair for the EPA, s. 9 Approval to require that Darling International Moorefield measure odour removal efficiency of the biofilter when what is relevant is the quality of odour emissions emanating from the biofilter and practical efforts to mitigate odour impacts to nearby sensitive receptors?
