Project Number: 173601 (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 SO 2 - sulfur dioxide PM
- total particulate matter, suspended in the atmosphere, including PM 10 and PM 2.5, as

represented PM 10 - total particulate matter equal to or less than 10 microns in diameter, including PM 2.5, as

represented PM 2.5 - particulate matter equal to or less than 2.5 microns in diameter CO

- carbon monoxide NH 3 - ammonia H 2SO4 - 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 NH 3 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
