An unknown volume of oil was released into the subsurface. During excavation activities, groundwater was encountered in the excavation at approximately 4 feet below ground surface. One excavation groundwater sample (GW01) was collected and submitted for laboratory analysis of BTEX. Laboratory analytical results received on January 15, 2016 indicated that benzene exceeded the CGWQS at 87.1 µg/L. Excavation soil and groundwater analytical results will be summarized in a supplemental report. A topographic Site Location Map showing the general location of the release is provided as Figure 1. 400972729 true 2016-01-15T00:00:00-07:00 40.193911 -104.935524 FEE 1 0 0 false <_x0032_7_approved>true S false Tank Battery Pad Unknown 0 0 0 0 false false false false true 0 2016-01-18T09:12:39.423-07:00 The volume of the release is unknown. 401021789 401021789 FORM 19 SUBMITTED 401021789.pdf 401021789 401021793 TOPOGRAPHIC MAP 014216020_FIG01_SL.pdf 632071 401021789 401021794 OTHER 24 Hour Email Notification.pdf 106338 401021789 401027033 OTHER Rademacher F27 041316.pdf 11972638 401021789 1 SPILL 2016-01-15T00:00:00-07:00 Weld County Roy Rudisill
