Air Quality Regulation

Permitting Local, state and federal air quality regulations help protect the quality of our air by limiting air pollution from industries and other air pollution sources. While all sources of air pollution must comply with Air Quality Regulations, some industries and businesses must also apply for Permits to Construct and Operate Air Pollution sources. Certain other facilities must register their air pollution source or submit notifications. You should contact our office if you think you might need an Air Quality Permit, need to Register, or need to submit a notification.

Permitting

If your business, activity or facility emits substances into the outside air, you may need an Air Quality Permit. Permits set forth specific compliance obligations and meet federal and state requirements. Air quality permits ensure that permittees know what their air quality obligations are and how to comply with those obligations.

Must I Submit an Emissions Inventory?

Title V sources and non-Title V sources with NOx or VOC emissions greater than 25 tons per year must conduct an emissions inventory annually. Non-Title V sources with NOx and VOC emissions of less than 25 tons per year must conduct an emissions inventory every five years, to coincide with permit renewal. Facilities should contact the Permitting Manager by email or by telephone at (336) 703-2440, if they think they may be required to submit an inventory but have not been notified.

Regulatory Basis for EI Requirement: Rules 3Q .0207 and 3D .0202 of the Forsyth County Air Quality Technical Code require facilities to quantify actual air pollutant emissions and report the data to the Forsyth County Office of Environmental Assistance and Protection.

Use of EI Data: Emissions inventory data are used in air quality planning, toxic risk assessment, determination of permit fees, satisfaction of Federal emission reporting requirements, and other related purposes.
