Managing Air ContaminantsSubstances emitted into the air capable of
• Injuring health or safety • Injuring property or any life form• Interfering with visibility• Interfering with the normal conduct of
business• Causing material physical discomfort• Damaging the environment

Emission Management Approaches
• Emissions released at the facility
• Concentrations beyond the facility
• Technology and management practices
• Measurement, monitoring and reporting
• Economic instruments

Emission Management for Cannabis Production
• Emission Regulations• Agricultural Boilers
• Site-specific Permits• Cannabis cultivation• Reciprocating engines

Scope of Potential Regulation
![Page 10: Cannabis Production and Processing Operations · Cannabis Production and Processing Operations. MANAGING AIR EMISSIONS. Julie Saxton PhD P.Chem. AIR QUALITY PLANNER. Esther Bérubé](https://reader033.vdocuments.net/reader033/viewer/2022052804/604db9cb7c8820455e5693dc/html5/thumbnails/10.jpg)

Measures controlling what is discharged:
• Enclosing or containing key emissions sources
• Treating air with activated carbon
• Limiting additional VOC sources
Potential Regulation

Esther Bérubé](https://reader033.vdocuments.net/reader033/viewer/2022052804/604db9cb7c8820455e5693dc/html5/thumbnails/11.jpg)
11
Measures controlling how discharges can occur:
• Preventing the release of fugitive or uncontrolled emissions
• Minimizing risk during airshed air quality degradation
• Preventing impacts near sensitive receptors

Measures providing evidence of effectiveness:
• Approved emissions management plan
• Monitoring for odorous air contaminants beyond property boundary
• Compliance with other applicable regulatory requirements
• Record keeping
