Policy Drivers

• Odour Management Policy Development Plan

• Regional Ground-Level Ozone Strategy

6

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

7

Emission Management Approaches

• Emissions released at the facility

• Concentrations beyond the facility

• Technology and management practices

• Measurement, monitoring and reporting

• Economic instruments

8

Emission Management for Cannabis Production

• Emission Regulations• Agricultural Boilers

• Site-specific Permits• Cannabis cultivation• Reciprocating engines

9

Scope of Potential Regulation

10

Measures controlling what is discharged:

• Enclosing or containing key emissions sources

• Treating air with activated carbon

• Limiting additional VOC sources

Potential Regulation

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

Potential Regulation

12

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
