Emission Sources - Maximum Allowable Emission Rates

Permit Number 1

This table lists the maximum allowable emission rates and all sources of air contaminants on the applicant’s 

property covered by this permit. The emission rates shown are those derived from information submitted as 

part of the application for permit and are the maximum rates allowed for these facilities, sources, and related 

activities. Any proposed increase in emission rates may require an application for a modification of the 

facilities covered by this permit.

(1) Emission point identification - either specific equipment designation or emission point number from plot 

plan.

(2) Specific point source name. For fugitive sources, use area name or fugitive source name.

(3) VOC - volatile organic compounds as defined in Title 30 Texas Administrative Code § 101.1

NOx - total oxides of nitrogen

SO2 - sulfur dioxide

PM - total particulate matter, suspended in the atmosphere, including PM10 and PM2.5, as 

represented

PM10 - total particulate matter equal to or less than 10 microns in diameter, including PM2.5, as 

represented

PM2.5 - particulate matter equal to or less than 2.5 microns in diameter

CO - carbon monoxide

NH3 - ammonia

H2SO4 - sulfuric acid

Pb - lead

Hg - mercury

(4) Compliance with annual emission limits (tons per year) is based on a 12-month rolling period.

(5) Emission rate is an estimate and is enforceable through compliance with the applicable special 

condition(s) and permit application representations.

(6) The hourly Hg emission rates apply based on the 30-day rolling average hourly emission rate.

(7) The hourly NH3 emission rate is applicable as a 24-hour rolling average.

(8) The hourly VOC emission rates apply based on the 12-month rolling average hourly emission rate.
