Braun Intertec conducted a site remediation involving the removal and disposal of approximately 100,000 cubic yards of impacted soil resulting from a pipeline gasoline release. The client’s objective was to remove all impacts to avoid possible long-term liabilities. Following initial emergency response actions completed by others, Braun Intertec worked with the Client to develop an excavation and sampling strategy and to negotiate optimal rates with disposal facilities. Project activities by Braun Intertec consultants included remedial alternatives analysis, liability estimates, project management, oversight of soil removal and transportation contractors, confirmation sampling, data evaluation, preparation of a Response Action Completion Report (RACR) and coordination with the state regulatory agency. Approval for site closure was obtained from the TCEQ under its Corrective Action Program in accordance with the requirements of the Texas Risk Reduction Program (TRRP).
The soil removal activities included field screening of excavated soil to facilitate the segregation of impacted material and clean overburden. Impacted soils were also segregated by Class 1 and Class 2 non-hazardous waste to help control costs. Confirmation samples were collected on a 40-foot grid from the sidewalls and floor of the excavation. Our consultants coordinated with the local electric utility to relocate support structures for an overhead electric transmission line that crossed the excavation area. In addition, two pipelines were temporarily relocated to allow for the excavation of impacted soil to a depth of 20 feet along approximately 1,000 feet of pipeline right-of-way (ROW). Our consultants subcontracted the compaction testing of soil placed back in the pipeline ROW and assisted in the procurement and testing of suitable fill used for site restoration.

The team on-site took great care to limit total soil removed and to classify the soil accurately for disposal without mixing more heavily impacted soils. Closure under the TCEQ Texas Risk Reduction Program was achieved with no post-closure care requirements and the site was restored to the satisfaction of the landowner as negotiated by the Client.
