Assistance Tools for the National Emission Standards for Hazardous Air Pollutants

Tools for complying with NESHAP rules to reduce emissions from facilities that are major and area sources.

 

Hazardous air pollutants (HAP) are pollutants that are known or suspected to cause serious health effects or adverse environmental effects. Regulations have been put in place to decrease the releases of 187 hazardous air pollutants into the environment. Exit the TCEQ

The National Emission Standards for Hazardous Air Pollutants (NESHAP) rules list the specific requirements that facilities must follow to accomplish these reductions. These rules may apply to both major and area sources.

  • Your facility is a major source if it emits or has the potential to emit 10 tons or more per year (tpy) of a single HAP listed in the Clean Air Act, or 25 tons or more per year of a combination of those HAPs. The potential to emit is the total air contaminants emitted if you were to operate 24 hours a day, 365 days per year.
  • Your facility is an area source if it is not a major source.

Here is a list of various recent NESHAP rules. Find tools to assist you in complying with these requirements by clicking on the links.

The TCEQ Air Permits Division also maintains a list of all NESHAPs by Subpart on its 40 CFR Part 63 Web page.
