Highly Reactive Volatile Organic Compound Emissions Cap and Trade Program

The HECT Program is a market-based cap-and-trade program that implements an annual HRVOC emission cap for applicable facilities in Harris County.

Program participants are required to use allowances to cover HRVOC emissions on an annual basis. The allowances available for use each year are capped at a level necessary to attain the National Ambient Air Quality Standard for ozone. Affected sites are required to participate.

For more information, including applicability requirements, refer to 30 TAC Chapter 101, Subchapter H, Division 6Exit the TCEQ Chapter 115, Subchapter H, Division 1 (Vent Gas Control)Exit the TCEQ and Chapter 115 Subchapter H, Division 2 (Cooling Tower Heat Exchange Systems)Exit the TCEQ.

HECT Reallocation

In accordance with 30 Texas Administrative Code Section 101.394(a)(1)(B), a 10% reduction from the existing HRVOC emission cap of 3,451.5 tons will begin with the 2014 calendar-year control period. The HRVOC emission cap will then be reduced in 5% increments at the start of each calendar-year control period for 2015, 2016, and 2017 for an overall 25% reduction. The final HRVOC emission cap is set at 2,588.6 tons for 2017 and all subsequent control periods.

The preliminary HRVOC allowance allocations for the 2014 and beyond control periods were revised because PL Propylene, Kaneka Pasadena, and ExxonMobil Chemical Baytown Chemical Plant were not in the appropriate industry sector. The TCEQ notified these companies, verified that all other sites were in the appropriate industry sector, and revised the HRVOC allowance allocations accordingly.

The final HRVOC allowance allocations for the 2014 and beyond control periods for eligible sites are now available. The TCEQ will begin updating the banking database on October 25, 2013, to ensure that the HRVOC allowance allocations are in the account for each eligible site by November 15, 2013.
