(Old R:Base Action Code = CORR - Correspondence (General)). On 2/22/94 ADEC approved ARCO's request to modify the quarterly sampling program that is part of the remedial action program at this site. Modifications include reducing the sampling frequency at certain monitor wells and discontinuing selected non-hydrocarbon analyses. |

GIS Position Updated |
Using Figure 2 from a Semiannual Groundwater Monitoring Report, May 1997, Fuel Pump Site, from Flour Daniel GTI, Inc., dated August 14, 1997, in conjunction with TopoZone Pro, entered the coordinates for this site. Metadata include No Topo Basemap, TopoZone Pro Street Map, Black and White Aerial Photo, on a Medium Size Map, View Scale 1:10,000, Coordinate Datum NAD83. High degree of confidence in accuracy of location. |

Update or Other Action |
Soil transport approval for 70 cubic yards of hydrocarbon contaminated soil excavated during pipeline installation. Soils to be sent to Alaska Soil Recycling for thermal remediation. |

Workplan Requested |
Soil contaminated with diesel and gasoline range hydrocarbons were identified in the pump area during a produced waterline installation. Concentrations above 1,000 milligrams per kilogram (mg/kg) extractable petroleum hydrocarbons (EPH) were obtained east and south of the pump area excavation. Xylenes appear to be the predominant fraction of benzene, toluene, ethyl benzene, and xylenes (BTEX) constituents. Diesel probably comprised the majority of released fuel.
Require Hilcorp to prepare a work plan for the sampling of existing monitoring wells.

Document, Report, or Work plan Review - other |
2021 Interim Groundwater Monitoring Report – ADEC Comments. The report recommends sampling monitoring wells an additional time and moving the site towards closure. Request that Hilcorp provide an assessment of the site, including groundwater flow characteristics. Include a narrative site history. The assessment should be written with enough detail to make a closure decision. Are the remaining wells in a location that is representative of historical groundwater impacts? Evaluate the site and determine if additional assessment is necessary to close the site with confidence. |

Document, Report, or Work plan Review - other |
Present a cover letter in the work plan that identifies the name and address of qualified environmental professional who prepared the work plan.
Name and address of person who the work plan is prepared for at Hilcorp.
Where is the reserve pit on Figure A3? It is referenced in the text on page 6 in the work plan.
Identify who is responsible for identifying and managing impacted soils prior to the QEP arriving on site?
The Field Sampling Guidance document has been updated to 2022. Please update your references and review the new guidance document.
Section 3.0. PID screening is not an option for determining if soils are clean. A PID may be used to segregate soils, but only laboratory testing is a valid method to determine the fate of soils. Using an arbitrary number of 20ppmV as a cut off is not valid. See ADEC Field Sampling Guidance 2022. Soils exhibiting odor, field screening detections, staining or other indicators of contamination will be subject to laboratory testing.
Page 7, 1st paragraph. The Field Sampling Guidance document states “the work plan will identify the collection sampling and frequency of sample.” Please include in these factors in this work plan.

Long Term Monitoring Workplan or Report Review |
It appears that the monitoring wells at this site have not been sampled for PAH compounds. During the next sample event site wells should be tested for PAH compounds in preparation for having data to close the site. Well FG-10 will be sampled until it meets the cleanup criteria for two sample events. |

Long Term Monitoring Workplan or Report Review |
As this site is moving toward closure, all remaining monitoring wells should be tested for PAH compounds to be assured that they meet cleanup standards. This should be added to the workplan. |
