PST to TRRP: Making the Transition

Releases from underground or aboveground storage tanks where the release is reported on or after September 1, 2003, are subject to the Texas Risk Reduction Program (TRRP) rule (30 Texas Administrative Code [TAC] 350). The following is a list of guidance and other sources of information on the regulation of PST sites under TRRP.

PST Release Determination Guidance

A guidance document on release determination is available: Investigating and Reporting Releases from Petroleum Storage Tanks (RG-411). All procedures and policies in this new guidance must be followed for any PST releases reported to the agency on or after September 1, 2003.

The purpose of the guidance is to explain the requirements of the TCEQ regarding the investigation and reporting of leaks, spills, and releases from underground and aboveground storage tanks. It supercedes all previously issued guidance related to release determination, and discusses PST releases in light of the new TRRP requirements, which took effect September 1, 2003.

Comparison of 30 TAC 334 and 30 TAC 350

This guidance document compares the PST and TRRP rules—30 TAC Chapters 334 and 350, respectively.

For the complete list of guidance currently available on application of the TRRP rule, see TRRP Guidance and Forms.

Determining Which Releases Are Subject to TRRP

A new procedure for determining when releases are subject to TRRP is now available. This procedure applies to the PST Program, Corrective Action Program, and all other TCEQ Remediation Division program areas. This document is incorporated into Investigating and Reporting Releases from Petroleum Storage Tanks (RG-411) and is also available as a stand-alone document.

Using the new TRRP screening process involves (in part) completing the Tier 1 Ecological Exclusion Checklist (TRRP Figure : 30 TAC §350.77(b)). This checklist is available in three formats (Help with downloading files):

Application of TRRP to LPST Cases

Information from the TCEQ Remediation Division on Application of TRRP to LPST Cases describes some important information on these two programs. For more information on TRRP, see these Web pages:
