Questions

Small Air Permit: what people ask

Do small sources need an air permit?

Often, but your state or local air agency decides. Federal rules require each state plan to have enforceable procedures to review the construction or modification of a facility and to stop it if it would violate the control strategy or interfere with air quality standards.

What is a permit by rule in Texas?

TCEQ describes a permit by rule as the state air authorization for activities that produce more than a de minimis level of emissions but too little for other permitting options.

Source: tceq.texas.gov

When does a source become major?

Under Title V, a source that emits or could emit 100 tons a year or more of a regulated air pollutant is major. Lower thresholds apply to hazardous air pollutants (10 tons of one, 25 tons combined) and in serious, severe or extreme ozone nonattainment areas.
