| While addressing a COGCC Field Inspection Corrective Action (Document No. 689302124) to treat or dispose of oily waste within the tank battery secondary containment, Caerus field staff noticed the secondary containment liner was compromised. On November 11/13/2018, soil samples (CONT MID (1'), CONT E (1'), CONT E (3')) were collected from soil beneath the compromised liner to verify that fluid had left secondary containment. All soil samples were submitted for laboratory analysis of all analytes listed in COGCC Table 910-1. On 11/23/2018, it was reported that TPH and Benzene exceedances were present in all samples collected on 11/13/2018. Exceedances for pH were also reported for samples CONT E (1’) and CONT E (3’) as well as Benzo(a)pyrene for sample CONT E (1’). Laboratory analytical is attached and summarized in Table 1. A soil sample location diagram will be provided in a Supplemental Form 19. |
