The Ministry of the Environment, Conservation and Parks (MECP) has recently announced new initiatives through the Made-in-Ontario Plan to bolster resources and tools necessary to hold emitters accountable for their actions. As part of the proposal, the MECP will also be introducing and updating certain guidelines to establish consistency when addressing odour and noise concerns.  Among these updates, the introduction of the EASR (Environmental Activity and Sector Registry) in Ontario simplifies the process for some environmentally relevant activities. One of the guidelines to be introduced includes the Proposed Land Use Compatibility Guideline which consolidates several D-series guidelines into one document. Upon finalizing and approval of the proposed Land Use Compatibility Guideline, the document will replace the former guidelines, specifically:

• D-1 Land Use Compatibility
• D-2 Compatibility Between Sewage Treatment and Sensitive Land Use
• D-4 Land Use on or Near Landfills and Dumps
• D-6 Compatibility Between Industrial Facilities

D-3 Environmental Considerations for Gas or Oil Pipelines and Facilities, and D-5 Planning for Sewage and Water Services and its subsections will not be affected by the newly proposed guideline. What Is The Proposed Guideline About? The new guideline intends to replace the former D-1, D-2, D-4, and D-6 guidelines to provide improved guidance for Land Use Compatibility Studies between sensitive land uses and major facilities. As core cities and areas undergo intensification land use planning between sensitive use and employment area plays an important role to avoid potential adverse effects and impacts between the two. Where the previous guidelines only provided characteristics for classifying major facilities based on the engineer’s assessment, the Proposed Land Use Compatibility Guideline establishes a 2-step approach to determine a Class and its associated Area of Influence (AOI) and Minimum Separation Distance (MSD) for a major facility. Based on the proposed guideline, the first approach is to find out if the subject site falls under a list of ‘Select’ major facilities with predefined Class, AOI, and MSD. These select major facilities include the following activities and operations:

• Aggregate Operations
• Asphalt Manufacturing
• Cannabis Production and Production and Processing Facilities
• Cement Manufacturing
• Chemical Product Manufacturing
• Composting Facilities
• Concrete (Ready-Mix)
• Industrial Anaerobic Digesters
• Food Manufacturing
• Industrial Food Mills (Non-Agricultural)
• Landfills and Dumps
• Meat and Meat Product Processes
• Metal and Glass Parts Manufacturing
• Oil Refinery
• Paint/Coating Operations
• Paper Manufacturing
• Plastics Manufacturing
• Recycling Facilities – General and End-of-Life Vehicles
• Scrap Yards
• Steel Mills
• Waste Transfer Stations
• Sewage Lagoons
• Municipal and Private Communal Wastewater Facilities – Small and Large

For facilities with no facility-specific AOI and MSD, the Class and its associate AOI and MSD will be defined based on the magnitude of the potential adverse effects, potential noise/vibration, dust and odour impacts, and the scale of its operations. The Ministry has also expanded the class classification from 3 to 5 different classes, which provides better categorization when it comes to assigning classes to facilities with no predefined AOI and MSD. The proposed Classes and its associated AOI and MSD are as follows: For major facilities of greater complexity that cannot easily be classified using the above table, land use planning authorities can classify a major facility based on its characteristics as per below: Proper compatibility assessments must be completed to avoid adverse effect and impacts in the future. When sensitive uses are proposed within the AOI of major facilities or vise versa, further noise, dust, and/or odour compatibility studies must be undertaken to determine whether or not the proposed development would be suitable for the surrounding land uses. Additionally, the MECP will require an odour control report in Ontario to be submitted as part of the assessment process. How SONAIR Can Help Whether it’s a Land Use Compatibility and Mitigation Study or assessments in the aspect of air quality, noise/vibration, or odour to support your planning application submissions, SONAIR can certainly assist you with it. Our engineers and consultants have completed hundreds of compatibility studies in support of planning applications and have established great working relationships with municipalities, planners, and developers. Additionally, we provide assistance with obtaining a certificate of property use to ensure compliance with environmental regulations.
