Mr. Lewis and Mr. Rozsypal will address the recent rule changes to the Texas Administrative Code Chapters 350 pertaining to the Texas Risk Reduction Program (TRRP) and Chapter 334 pertaining to Underground and Aboveground Storage Tanks. In response to legislation passed in 2007, the Texas Commission on Environmental Quality (TCEQ) has revised its rules by removing petroleum storage tank (PST) corrective action sites from TRRP rule requirements effective March 19, 2009. In response to federal law (The Energy Policy Act of 2005), the TCEQ has revised its Chapter 334 technical rules by adding secondary containment requirements for new underground storage tank (UST) construction effective January 1, 2009.

These rule changes will also result in changes to PST guidance. The TRRP Regulatory Guidance document RG-366 series has been undergoing revision to reflect the 2007 and 2009 amendments, corrections, and other updates. Several long-anticipated guidance documents are progressing in workgroups, including representative concentrations for human and ecological exposures and closure of waste management units. A related guidance document (RG-428), regarding preparation of drinking water survey reports, has been revised and will soon be re-issued.
