W&M Procures Closure After Pipeline Spill in South Texas

Options & Tools Available in Addressing Historical Site Contamination Issues

Once you have documented your property is contaminated, what are your options? Once you receive that Phase II Investigation report that shows your property has some contamination issues, don’t panic yet. Everyone has heard the horror stories about millions spent on cleaning up site contamination that occurred half a century ago. Fortunately, we have come a long way in understanding behavior, fate and transport of chemicals in the environment.  Additionally, site cleanup decisions are almost entirely risk-based, meaning contaminated soil does not need to be remediated to background conditions, and groundwater does not always require treatment to potable water standards. In Texas, most contaminated sites are subject to the technical regulations under the Texas Risk Reduction Program (TRRP) or the Petroleum Storage Tank (PST) rules. Both of these programs have evolved in pragmatic ways to rely heavily on evaluating individual exposure pathways and requiring response actions only for those pathways

Buyer, Be Calm: Effectively Navigating Contaminated Sites and Site Closures

What should you do when you find out your property is contaminated? Which Texas program and regulations apply to your site? First, you need to determine what type of operations are/were conducted at your site. Different programs need to be followed depending on the type of operations that have taken place. In Texas, most contaminated sites are subject to the technical regulations under the Texas Risk Reduction Program (TRRP) or the Petroleum Storage Tank (PST) rules. Second, you should determine which program is appropriate to seek regulatory approvals and closure. Programs regulated by TRRP include the Voluntary Cleanup Program (VCP), Innocent Owner/Occupant Program (IOP), Drycleaner Remediation Program (DCRP), and Corrective Action (CA), while PST rules and regulations apply to Leaking Petroleum Storage Tank (LPST) cases. For example, a filling station will need to be addressed under the PST Program, while a dry cleaner will need to be addressed under the

W&M Closes Contaminated Houston Site Through MSD

W&M conducted a soil removal response action for a contaminated property and detected total petroleum hydrocarbons (TPH) in the C12-C28 boiling point range at concentrations in exceedance of the Texas Commission on Environmental Quality (TCEQ) Texas Risk Reduction Program (TRRP) residential assessment level (RAL).



W&M Closes Four Voluntary Cleanup Program Sites

2017 kicked off on a good note as four of W&M’s clients received closure letters from the Texas Commission on Environmental Quality (TCEQ) for real property that had been entered into the Voluntary Cleanup Program (VCP). The most challenging closure was for a former light industrial facility in West Texas that had a release of chlorinated volatile organic compounds (VOCs) into the shallow portions of the Ogallala Aquifer. The Ogallala is a highly valued source of water for agricultural, industrial and domestic use in West Texas and beyond.  The affected portion of the aquifer extended to a depth of nearly 100 feet.  Many years of monitoring by previous consultants had shown that the VOCs were not being degraded at a very rapid pace, so W&M recommended that the client seek a Municipal Setting Designation (MSD) to restrict the use of groundwater from the affected area.  W&M worked closely with the
