Information for the 2007 Emissions Inventory Request Why you have received this emissions inventory request? The Texas Commission on Environmental Quality’s (TCEQ) Emissions Assessment Section (EAS) is responsible for compiling and reviewing information regarding emissions from stationary sources in Texas. Per 30 Texas Administrative Code (TAC) '101.10, a regulated entity is required to submit an annual emissions inventory if it meets the reporting requirements for submitting an emissions inventory or submit a special emissions inventory if it is requested by the executive director or designated representative of the commission. You may have received this request because your regulated entity meets the reporting requirements for submitting an annual emissions inventory or you have been selected to submit a special emissions inventory. The current version of 30 TAC §101.10 is located in the 2007 Emissions Inventory Guidelines or you may visit the TCEQ’s main web site at http://www.tceq.state.tx.us. If you determine that your regulated entity meets the reporting requirements of 30 TAC §101.10 for calendar year 2007, you must complete and submit an emissions inventory; otherwise, you must provide a written statement explaining how your regulated entity does not meet the reporting requirements of 30 TAC §101.10. The completed emissions inventory or written explanation must be received by the TCEQ by March 31, or within 90 days of the request which ever is later. If your regulated entity does not meet the reporting requirements of 30 TAC §101.10, you have received this request because your account has been selected to report under the special emissions inventory provisions of 30 TAC '101.10(b)(3). A special emissions inventory is being requested for regulated entities located in a near nonattainment county or an affected county of Texas whose actual emissions totaled 10 tons per year or more of volatile organic compounds (VOC), or 25 tons per year or more of nitrogen oxides (NOx), and for regulated entities located in the former severe and serious 1-hour ozone nonattainment areas whose emissions meet the thresholds detailed in Chapter 1 of the 2007 Emissions Inventory Guidelines. The special inventory counties are: Bastrop, Bexar, Brazoria, Caldwell, Chambers, Collin, Comal, Dallas, Denton, El Paso, Fort Bend, Galveston, Gregg, Guadalupe, Hardin, Harris, Harrison, Hays, Henderson, Hood, Jefferson, Liberty, Montgomery, Nueces, Orange, Rusk, San Patricio, Smith, Tarrant, Travis, Upshur, Victoria, Waller, Williamson, and Wilson. The completed special emissions inventory must be received by the TCEQ by March 31, or within 90 days of the request which ever is later. 2007 Emissions Inventory Guidelines: What=s new? The Emissions Inventory Guidelines exists as two documents. The 2007 Emissions Inventory Guidelines details who is responsible for completing an emissions inventory and how to create a complete emissions inventory submission. The 2007 Emissions Inventory Forms and Instructions provides instructions for filling out all EAS forms, blank EAS forms, and a list of abatement and contaminant codes. Some of the new requirements and considerations are: $ $ a special inventory request for the former severe and serious 1-hour ozone nonattainment areas (see above paragraph and Chapter 1); further clarification that addresses annual aggregate heat input and NOx factors for combustion sources that burn multiple fuels (Chapter 6);

the preferred emissions inventory structure for reporting blowdown operations (Chapter 3); further clarification that defines highly reactive volatile organic compound (HRVOC) service for cooling towers or flares, for emissions inventory purposes; the request for providing material throughput data for oilfield storage tanks; additional discussion of miscellaneous VOC sources that are potentially under reported or unreported in the emissions inventory (Appendix A); further guidance in the emissions determination section of the cooling tower technical supplement to address method detection limits and monitoring of select VOC species (Technical Supplement 2); revisions to the equipment leak fugitive technical supplement to address the use of nonpegged screening values above 100,000 ppm in the correlation equations, address the use of monitoring data from a prior year, and the addition of emission factors for pressurized railcar loading operations (Technical Supplement 3); changes to the flare technical supplement to address flares in HRVOC service and reporting emissions from a shared flare (Technical Supplement 4); further guidance in the aboveground liquid storage tank technical supplement to address floating roof tank landing losses, tanks storing hot products, tanks with a liquid heel, and oilfield storage tanks (Technical Supplement 6); revisions to the sample applicability letters to include a note concerning updated reporting requirements for emissions events and scheduled maintenance, startup, or shutdown activities per 30 TAC '' 101.201 and 101.211 (Appendix B); the addition of a total number of Excess Opacity Events to the Site Quantifiable Event Totals (Chapter 4); and further guidance for determining if the Emissions Events Certifying Signature needs to be signed (Chapter 6).
The EAS is not including the 2007 Emissions Inventory Guidelines or the 2007 Emissions Inventory Forms and Instructions with this package.
