The volume of the release in unknown. Internal corrosion was identified upon excavation of the dumpline. The impacted soil was excavated and confirmation soil samples were collected. Approximately 300 cubic yards of soil were excavated and transported to Buffalo Ridge Landfill in Keenesburg, Colorado for disposal. Confirmation soil samples were collected from the excavation and the analytical results and excavation details are provided below. A topographic Site Location Map showing the general location of the release is attached as Figure 1. 329106 400808425 true 2015-03-12T00:00:00-06:00 40.192707 -104.692232 FEE 0 0 0 false <_x0032_7_approved>false I false Tank Battery Unknown 0 Unknown 0 0 false true false true false 0 2015-03-12T14:57:29.53-06:00 An unknown volume of produced water was released onto the subsurface. 400808425 400808425 FORM 19 SUBMITTED 400808425.pdf 400808425 400808720 OTHER 24hr Email Notification.pdf 90582 400808425 400808721 ANALYTICAL RESULTS Table 1 - Soil.pdf 11787 400808425 400808723 ANALYTICAL RESULTS Analytical Reports.pdf 1745367 400808425 400808785 TOPOGRAPHIC MAP 014215035_HSR-RAININ_13-29_SL.pdf 309872 400808425 400809052 SITE MAP 014215035_HSR-RAININ_13-29_SITE.pdf 253600 400808425 1 2015-03-13T00:00:00-06:00 0 0 true false false false false false 22 false On March 6, 2015, four soil confirmation sidewall samples (N01@12', E01@12', S01@12', and W01@12') and one base soil sample (B01@20') were collected from the excavation and submitted for laboratory analysis of TPH, BTEX, pH, and EC. Laboratory analytical results for the soil samples indicated that base confirmation soil sample B01@20' exceeded the COGCC allowable level for TPH at a concentration of 550 mg/kg. The laboratory analytical results for the sidewall confirmation soil samples (N01@12', E01@12', S01@12', and W01@12') indicated that that TPH, BTEX, pH, and EC were in compliance with COGCC allowable levels. On March 9, 2015, one additional base soil sample (B02@20') was collected from the base of the excavation and one soil sample (B03@22') was collected at a depth of two feet below the base of the excavation and submitted for laboratory analysis. Laboratory analytical results for soil samples B02@20' and B03@22' indicated that TPH and benzene concentrations exceeded the COGCC allowable levels. In addition, soil sample B03@22' exceeded the COGCC allowable levels for toluene and total xylenes. Soil assessment activities are ongoing at the site. The general site layout, excavation dimensions, and soil sample locations are shown on the Excavation Site Map attached as Figure 2. The soil sample analytical results are summarized in Table 1 and the soil laboratory analytical reports are attached. Additional analytical results and assessment details will be provided in a supplemental report.
