Potential Health and Environmental Issues

Volatile organic compounds

  • Ground-level ozone formation
  • Particulate matter formation
  • Odorous air contaminants

Nitrogen Dioxide Volatile Organic Compounds Ground Level Ozone sunlight, heat

Ground Level Ozone

  • More common in hot, sunny weather
  • Health effects
  • Eye, throat and nose irritation
  • Worsens lung and heart conditions
  • Environmental effects
  • Damages ecosystems and vegetation
  • Reduces crop yields
  • Damages buildings and materials

Reducing VOC Emissions

  • Regulated emissions
  • Specific industrial sites
  • Gasoline distribution
  • Industrial chemical product use
  • Infrastructure
  • Electric vehicle charging stations
  • Education and Outreach
  • Air quality advisories

Managing Air Contaminants

Substances 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

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
