Dirt, Sand, and Rock Quarries and Aggregate Processing Plants: Compliance Resources
APO Registration
A new state law, House Bill 571, requires certain aggregate production operations to register with the TCEQ. Aggregates are materials used in construction, including sand, gravel, crushed and broken limestone, crushed and broken granite, dirt, soil, or caliche. The TCEQ adopted new rules implementing HB 571 on June 13, 2012; you can find these new rules in 30 Texas Administrative Code, Chapter 342. Exemptions from this rulemaking can be found in Chapter 342.1(1)(E).
The new rules require commercial APOs to:
- register with the TCEQ beginning Sept. 1, 2012 (with a deadline of Oct. 30, 2012), and renew registration annually;
- pay registration fees; and
- undergo inspection every three years.
For additional information on registering your operation, visit the APO registration website.
APOs that submit a Notice of Audit to conduct a self-audit under the Texas Environmental, Health, and Safety Audit Privilege Act (Audit Act) with their initial registration may delay their inspection requirements until Sept. 1, 2015.
Under the Audit Act, certain documents and information gathered as part of an environmental self audit are privileged from disclosure. The Audit Act also grants certain immunities from administrative or civil penalties for violations voluntarily disclosed and corrected within a reasonable amount of time. For more information, please see Guidance on the Texas Environmental, Health, and Safety Audit Privilege Act (RG-173).
