Point Source Emissions Inventory
The Point Source Emissions Inventory is an annual survey of chemical plants, refineries, electric utility plants and other industrial sites that meet the reporting criteria in the TCEQ emissions inventory rule (30 TAC §101.10 
).
This Web page provides point source emissions inventory data along with tools and information of use to companies completing their annual questionnaires.

Point Source Emissions Inventory Trends
The table that follows gives point source emissions data for the last four completed calendar years, including information on routine industrial emissions in tons per year (tpy) for the sources that met the reporting requirements of Rule 101.10 and submitted an emissions inventory for that year. It lists the following pollutants: volatile organic compounds (VOC), nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), and particulate matter less than ten microns in diameter (PM10). Note that Inventory Trends are rounded to the nearest thousand.

Barnett Shale Area Special Inventory, Phase One
The TCEQ's Emissions Assessment Section (EAS) conducted a special inventory under the authority of 30 Texas Administrative Code §101.10 (b)(3) to determine the location, number, and type of emissions sources located at upstream and midstream oil and gas operations associated with the Barnett Shale formation.
As of June 16, 2010, the TCEQ has received special inventory data from companies that account for more than 99 percent of the 2009 production in the Barnett Shale formation. Specifically, data for 9,123 upstream leases/facilities and 519 midstream sites/facilities has been received. It should be noted that midstream sites/facilities process or transport gas from formations other than the Barnett Shale formation.
Operations were reported in all 23 counties that comprise the Barnett Shale area. County-level summary data is available here: Barnett Shale Phase One Results (Excel) (updated 03/30/2011).

Phase One Inventory Forms
Phase One Maps
Barnett Shale Special Inventory Phase One maps were developed using reported location data from upstream and midstream oil and gas sites.
These maps are in Portable Document Format (PDF). (Help with PDF.)
Barnett Shale Area Special Inventory, Phase Two
The Texas Commission on Environmental Quality (TCEQ) is requesting companies, including any affiliated subsidiaries, that own and/or operate leases and/or facilities associated with Barnett Shale oil and gas production, transmission, processing, and related activities to provide air emissions data and related information for calendar year 2009.
The completed and certified inventory data must be remitted to the TCEQ by January 14, 2011. Detailed information about this inventory and the information it is requesting can be found in the sample letter and enclosure link below.
Note: The TCEQ is conducting this special inventory under the authority of 30 Texas Administrative Code §101.10(b)(3). If the TCEQ has initiated a formal written request for this information, owners or operators are required to complete and submit this special inventory by the required date.
The inventory will collect information on:

HRVOC Flare Data Request
In accordance with Title 30 Texas Administrative Code (TAC) §101.10(b)(3) and §115.726(i), the Texas Commission on Environmental Quality (TCEQ) is requiring each company identified as a potential owner or operator of a flare that emits or has the potential to emit highly-reactive volatile organic compounds (HRVOC) as defined in 30 TAC §115.10 and subject to 30 TAC §115.725(d), including any affiliated subsidiaries, to provide hourly emissions-related data for gas streams routed to applicable HRVOC flares for the following two periods during Calendar Year 2006: May 29 through July 2; and August 15 through October 11, and all of Calendar Year 2009.
Further, for air- or steam-assisted flares, any information regarding the assist rate and configuration that is applicable for the time periods specified is also requested. While responses to these questions are strictly voluntary, you are strongly urged to provide this information to assist the TCEQ in developing more accurate baseline emissions to use in future ozone attainment demonstration SIP revisions.
Because the modeled attainment test for ozone is based on the predicted change from a baseline year to a future year, it is extremely important that the baseline year emissions are as accurate as possible. Therefore, the purpose of this request is to provide TCEQ with information to more accurately estimate historical flare emissions used in photochemical modeling to support federally required state implementation plan revisions. The TCEQ will use the requested information in conjunction with the findings of the TCEQ 2010 Flare Study, conducted by the University of Texas at Austin Center for Energy and Environmental Resources to better characterize historical (HRVOC) emissions.
Respondents are requested to submit data using the HRVOC Data Submittal Spreadsheet or similar format. Please include information for each flare in a separate file, named using the company’s RN and the specific flare’s EPN (example: RN123456789_Flare1). All hours should be reported as Central Standard Time (CST). Data may be submitted on a CD or DVD and mailed to the following address:
Texas Commission on Environmental Quality MC-164
P.O. Box 13087
Austin, Texas 78711-3087
Attn: Dick Karp
Alternatively, the data may be loaded on the TCEQ FTP server at ftp://amdaftp.tceq.state.tx.us/incoming/HRVOC_Flare using FTP Client software (e.g., filezilla) and anonymous for the login. Because this is a public FTP site, we recommend data files be password protected. After loading the data on the FTP site, please e-mail Dick Karp with the file protected password.

Detailed Data from the Point Source Emissions Inventory
The TCEQ collects information about air pollutants emitted from industrial point sources in Texas that is stored in our State of Texas Air Reporting System (STARS). Only those sites whose emission rates exceed the reporting applicability levels found in ( 30 Texas Administrative Code 101.10 ) are tracked. Currently, there are approximately 2,000 industrial sites updating emissions annually.
Site level summary emissions data is available in MS Excel format: Download 2010statesum.xlsx (281K). File updated January 2012.
The emissions are represented in tons per year during routine operations. To request detailed site specific data or reports, complete the Emissions Data Request Form (PDF) and fax it to 512/239-1515. Point source emissions data may also be obtained by contacting the TCEQ IR Data Clearinghouse.
Tools for Completing the Point Source Emissions Inventory Questionnaires
The following information is for the benefit of those companies submitting an annual emissions inventory report under 30 TAC §101.10 .
