Air quality permits

An air operating permit is a document that combines all requirements for:

• Operation and procedures
• Applicable rules
• Emission standards
• Monitoring
• Recordkeeping
• Reporting

An air operating permit is required for major sources (such as power plants, oil refineries, and industrial facilities) that emit or have the potential to emit 10 tons per year or more of hazardous air pollution, or 25 tons per year or more of a combination of hazardous air pollution.

The location and type of burning you are planning will determine whether you need a permit. Types of burn permits are:

• Agriculture burning
• Fire training burning
• Asbestos demolition/renovation
• Silvicultural (forest) burning

A general order is issued for similar sources of air pollution, instead of a series of individual notice of construction permits.

A notice of construction permit is required before installing a new source of air pollution or modifying an existing source of air pollution.

A Prevention of Significant Deterioration permit applies to new large facilities or major changes at existing large facilities that could increase air pollution in an area that meets air quality standards. The intent is to prevent air quality in an area from getting worse.
