Leaking Petroleum Storage Tank Sites Move to Chapter 334

On February 25, 2009, the commission adopted changes to Chapter 334, Underground and Aboveground Storage Tanks and Chapter 350, Texas Risk Reduction Program (TRRP) to remove Leaking Petroleum Storage Tank (LPST) sites from TRRP. These rules are effective on March 19, 2009. All LPST sites must follow the requirements of the Chapter 334 rule and guidance.

The rule changes may influence the corrective action necessary at LPST sites currently under TRRP. Responsible parties/persons should evaluate site information to determine if the closure requirements under Chapter 334 rules and guidance have been met or if additional assessment and cleanup is needed.

Any TRRP reports submitted (APAR, RAP, etc.) will not have to be re-submitted using the 334 report formats. Any reports submitted on or after May 1, 2009 should use the applicable 334 rules and guidance formats.

Hurricane Ike's Effect on Laboratory Samples

Due to the September 2008 preparation, evacuation, and/or recovery activities associated with the Hurricane Ike event along the Texas coast in the Galveston/Houston area, environmental laboratories in that area impacted by the hurricane's movements may report holding time and temperature preservation issues for samples collected Friday, September 5, 2008 through Thursday, September 11, 2005. These activities may include a) the mandatory and/or voluntary evacuation of the laboratories in advance of the hurricane's anticipated and/or actual landfall, b) the couriers, responsible for delivering the samples to the laboratory, not entering the area by land or by air until after the hurricane conditions had subsided, and c) the laboratory's recovery and return to routine operating conditions following the hurricane event.

The agency has developed guidelines with information regarding the evaluation of sample data and reimbursement issues when sample delivery and/or analysis was impacted by the hurricane event.

Laboratory Accreditation

As of July 1, 2008, analytical data submitted to us that is related to permitting or remediation must be generated by a lab that is accredited through the Texas Laboratory Accreditation Program under the NELAP standard for matrices, methods, and parameters of analysis, unless:

  • The lab is an in-house lab and meets one of these criteria:
    • The lab performs work for its owner, for another company with a unit located on the same site, or without compensation for a governmental agency or charitable organization.
    • The lab is in another state and is accredited or inspected by that state.
  • The lab is accredited under federal law.
  • The data are needed for emergency-response activities and no TLAP-accredited lab is available.
  • The lab supplies data for which we do not offer accreditation.

Starting July 1, 2008, we will accept analytical data for a permitting or remediation decision only if the data comply with all applicable rules for the regulatory program involved and:

  • the lab generating the data is NELAP-accredited by TLAP,
  • we have approved an exception as described above, or
  • the data were generated on or before June 30, 2008.

For additional information on these requirements, see the NELAP page.

Report Required for Sites with Groundwater Contamination

The Texas Water Code (TWC) §26.408 requires the TCEQ, within 30 days of the date the TCEQ receives notice or otherwise becomes aware of groundwater contamination, to notify owners and users of private drinking water wells that may be affected by the groundwater contamination (ingestion standards exceeded).

The TCEQ needs critical local drinking water information within a short time frame to implement TWC §26.408. Please refer to the TWC §26.408 web page for guidance and information on this program.

TCEQ to HOST Training

TCEQ will host ITRC 2-day training course on LNAPL release management and remediation technology, November 18-19, 2015, in Austin

Light nonaqueous-phase liquids (LNAPL), such as gasoline and diesel, present challenges for corrective action of contaminated soil and groundwater.

Learn about solutions to the problems that LNAPL present and better understand and manage risks from LNAPL contamination by attending this 2-day training course “Light Non-Aqueous Phase Liquids: Science, Management, and Technology.” Registration is now open for this course being presented by the Interstate Technology and Regulatory Council (ITRC) for the first time in Texas, hosted by the TCEQ.

The course is designed for environmental professionals, consultants, regulatory and industry staff. View more information at the Registration link above or contact Paul Lewis at
