Information for Aggregate, Asphalt and Concrete Batch Plants

Fugitive Dust Control Techniques and Businesses

Air quality permits for aggregate, asphalt and concrete batch plants require control of fugitive emissions from equipment and haul roads.

Test Methods for Visible Emissions

EPA Reference Methods for visible emissions are used for many industries and are required in many regulations and permits. These EPA test methods for visible emissions include Reference Methods 9 and 22.

EPA Reference Method 22 is a test method procedure used to detect visible emissions coming from fugitive sources, such as stockpiles and haul roads, at industrial facilities. An observer determines the amount of time that visible emissions (dust) occur during a specific time period and records their observations. Some New Mexico air quality permits require Method 22 to be used to verify whether visible emission standards are being met at facilities.

For more information about Method 22 and answers to frequently asked questions:

View Method 22 – Summary and FAQ.pdf

View Method 22 – 40 CFR 60 Appendix A-7.pdf

A record keeping example form may be viewed at: Method 22 – Observation Form.pdf

EPA Reference Method 9 involves the determination of plume opacity by qualified observers. Many stationary sources discharge visible emissions into the atmosphere; these emissions are usually in the shape of a plume. The method includes procedures for the training and certification of observers, and procedures to be used in the field for determination of plume opacity.

New Source Performance Standards (NSPS) – (40 CFR Part 60, Subpart JJJ)

New Source Performance Standards (NSPS) are pollution control standards that set the level of pollution that a new or modified stationary source may produce. An NSPS has been established for all petroleum solvent dry cleaners having a total washer capacity of 84 pounds or more.

National Emission Standards for Hazardous Air Pollutants (NESHAPs) for Area Sources (40 CFR Part 63)

NESHAP regulations were developed to address toxic air pollutants generated from area sources.  “Area” sources are those sources that emit less than 10 tons per year of one Hazardous Air Pollutant (HAP), or 25 tons per year of all HAPs combined. To view all of the listed sources, visit the following links:
