Update or Other Action |
(Old R:Base Action Code = TECH - Technical Assistance). TECH was provided to Unocal for the installation of a generator building at the facility. Problems were encountered when Unocal selected a contaminated area to locate the generator building. Unocal decided to relocate the building in an area believed to be free of contamination, rather than excavate contaminated soils (approximately 300 cubic yards). |

Update or Other Action |
Hilcorp reported that sheen is day lighting at the ground surface after rainfall. The location of the seep is near the north central part of the facility between Tank 104 and a fuel storage area. The contaminated sites program has required that a spill assessment work plan be submitted to assess the extent of contamination and determine what remedial actions are necessary. |

Work plan approved to assess an area hydrocarbon staining near tank 104. Hand auger boings will be used to determine the extent of surface staining. Up to 20 borings may be used to explore the area. Assessment will include sampling existing groundwater monitoring wells and extending the analytical sampling suite into VOCs and SVOCs. |

Document, Report, or Work plan Review - other |
Reviewed the Road Stain and Seep Investigation Report dated October 2017. The report covered sampling of groundwater seeps south of the property, road staining in the northern portion and monitoring well sampling. Soils impacted at the road staining area were heavily contaminated. ADEC will require cleanup of this area. It appears that ground water seeps and surface water are not being impacted based on testing results. |
