Toxic Air Pollutants

What are Toxic Air Pollutants and how do I tell if my facility uses them?

The state of New Mexico has a Toxic Air Pollutants (TAPs) rule that limits emissions and can be found in 20.2.72.400-405 NMAC. These pollutants are different than the federally listed Hazardous Air Pollutants (HAPs) and should be checked against the products you use at your facility. The list of the state TAPs are found in Tables A and B in 20.2.72.502 NMAC.

New Mexico TAPs are mainly chemicals but also include some types of salts, metals, and asphalt fumes. TAPs may also be an ingredient in certain types of paints, solvents, and other materials. To find out if your facility has any TAPs contained in the materials you use in your processes, look at the material specification sheets and/or Safety Data Sheets (SDS) provided by the manufacturer.

If you find one or more of the pollutants on the TAPs list that is used at your facility, then you will need to determine the emission rate in pounds per hour to see if it is above the limit. Emission limits for some TAPs can be very low, such as in the tenths or hundredths of pounds per hour.

Depending on what the emissions may be, it could trigger the need for a permit. Some facilities are exempt from the TAPs regulation, but may fall under other existing regulations. The list of state TAPs is extensive and certain chemicals may have more than one name or identifier. If you are a small business and need help reviewing the materials you use in your on-site processes, contact the Air Quality Bureau’s Small Business Environmental Assistance Program at:
