Potts-Ildefonso complex - stony to very stony loam 165 13 1170 3719 1172 The produced water tank, located at the RWF 11-4 tank farm facility, developed a small hole near the bottom of the tank due to corrosion of the metal. This allowed produced water to flow out into the earthen SPCC containment structure where it infiltrated into the underlying soils. When the release was discovered, production personnel halted the transfer of fluids to the compromised tank. The tank was then drained of any remaining fluids and removed from service. The entire release was contained in the immediate vicinity of the compromised tank. Due to the dry soil conditions none of the fluids lost were recovered. The area impacted by the release has been remediated. When clean soil was encountered, the walls and bottom were field screened for hydrocarbon content. Field screening results indicated residual contaminant levels below the COGCC Table 910-1 standard of 500 ppm TPH in soil. Confirmation samples were collected and submitted to an accredited laboratory for analysis. Analytical results indicate compliance with Table 910-1 with the exception of benzo(a)pyrene on the north wall. The north wall was excavated an additional 2 feet and resampled for benzo(a)pyrene. Further remedial action, if warranted, will be based on this result. Impacted soils generated during remediation will be treated on-site with a bio-remediation product to levels which comply with Table 910-1 standards. 0 0 0 0 15 0 0 0 0 0 false false 0 0 false false false false false false false false true true false true 28 26 400650991 1 2014-07-25T00:00:00-06:00 false true false false The produced water tank, located at the RWF 11-4 tank farm facility, developed a small hole near the bottom of the tank due to corrosion of the metal. This allowed produced water to flow out into the earthen SPCC containment structure where it infiltrated into the underlying soils. The earthen SPCC containment is being replaced with a steel SPCC containment structure with an impervious plastic liner. In addition, the replacement tank is internally coated with poly liner. All new tanks are inspected prior to placing them into the containment structures to check for possible paint chips, faulty welds, or other factors which could lead to early corrosion of the metal. The SPCC inspectors will also conduct more detailed inspections of all tanks in the field to check for possible corrosion. false false false Thread was being aborted.
