Fuel Tank Removal for TxDOT Tollway 288 Expansion
SSCI was selected to accomplish the fuel tank removal of a former gas station on the TxDOT 288 Expansion Project. SSCI provided the engineering design, construction, and environmental field investigations for the tank removal. The fueling system consisted of two (2) 20,000-gallon underground storage tanks (USTs). One containing gasoline and the other diesel fuel. Please read below to see how this was accomplished one step at a time.
Asbestos and Lead-Based Paint Surveys
First step: SSCI performed an Asbestos and Lead-Based Paint Survey for demolition. The objective was to identify and sample suspect asbestos-containing materials (ACMs) and Lead-Based Paint Materials (LBPM) for the structure located on the Site. The survey was conducted in accordance with the Texas Asbestos Health Protection Rules (TAHPR) and National Emissions Standards for Hazardous Air Pollutants (NESHAP) for asbestos. A total of sixty-three (63) samples of suspect ACMs representing twenty-one (21) homogeneous areas were collected. A total of twelve (12) surfaces were tested from the interior portions of the building for LBPM. An x-ray fluorescence analyzer (XRF) was used to test the concentration of lead on painted surfaces. Once the Site was cleared for Asbestos and Lead-Based Paint the tank removal could begin.
Fuel Tank Removal - Clearing the Site
CLEARING THE SITE
Step 2: SSCI developed a Health and Safety Plan and a Work Plan to ensure all construction was done in accordance with the Site safety standards. Daily job safety analysis (JSA) meetings were held to reiterate Site safety.
Step 3: SSCI designed the demolition plan for the tanks and oversaw the construction work for the tank removals and disposals, according to TCEQ regulations.
Step 4: Once the tank removal was complete, SSCI collected soil samples in accordance with TCEQ regulation RD-411 to determine if contamination was present. SSCI then developed the remedial design for contaminated soil, and oversaw the over-excavation and non-hazardous waste disposal. When floor samples were unachievable due to heavy rain, the tank pit was filled and three (3) borings were installed to 26.5 feet with a track hoe.
Last Step: SSCI prepared the release determination report (RDR) for submittal to the TCEQ.
