EMISSION SOURCES - MAXIMUM ALLOWABLE EMISSION RATES
Permit Numbers 70492 and PSD-TX-1037

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. Any proposed increase in emission rates may require an application for a modification of the facilities covered by this permit.

EMISSION SOURCES - MAXIMUM ALLOWABLE EMISSION RATES

  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 30 Texas Administrative Code Section 101.1 PM-particulate matter, suspended in the atmosphere, including PM10. PM10-particulate matter equal to or less than 10 microns in diameter. Where PM is not listed, it shall be assumed that no particulate matter greater than 10 microns is emitted. NOX-total oxides of nitrogen SO2-sulfur dioxide NH3-ammonia CO-carbon monoxide H2SO4-sulfuric acid mist Pb-lead HCl-hydrogen chloride HF-hydrogen fluoride Hg-mercury
  4. Fugitive emissions are an estimate only.
  5. The cap becomes effective upon start-up of Spruce 2 Utility Boiler.

*Compliance with annual emission limits is based on a rolling 12-month period.

**Emission rates are based on and the facilities are limited by the following maximum operating schedule:

*Emission rates are based on the following operating schedule:

Hrs/day  24    Days/week 7    Weeks/year 52    or Hrs/yr 8,760
