Update or Other Action |
(Old R:Base Action Code = RAPR - Remedial Action Plan Review (CS)). CAP by Clearwater Environmental received 5/11/95. For site #2, tanks 5 and 6, proposed 1 soil boring which will be converted to MW. Sampling/analysis to prove closure of site. Proposed closure of site #5, tank 10. For site #7, tanks 12 and 13, proposed soil boring and possibly convert to MW. Depending on lab results, may do air sparging or natural attenuation. |

Update or Other Action |
(Old R:Base Action Code = RAPR - Remedial Action Plan Review (CS)). RAP by Clearwater Environmental received 5/11/95. Proposed closure of site #3, tank 7, as ground water contamination reported in error when site assessment conducted. Mix-up during possible decontamination or rinseate sample. Due to building foundation problems on site #4, tanks 8 and 9, proposed 2 inclined soil borings, 1 of which is to be converted to a MW. Possible Risk Assessment may be considered. For site #6, tank 11, proposed 1 inclined soil boring to be converted into a MW, conduct extensive analysis. Possibility of the existence of chlorinated compounds. |

Update or Other Action |
Revised CAP 2/21/96 submitted by RP on behalf of new RPCON, PRC Environmental Management, Inc. Seattle. |
Eleanor Hung |
| 5/7/1996 |
Update or Other Action |
(Old R:Base Action Code = SA1R - Phase I SA Review (CS/LUST)). Didn't follow QAPP: no field Q.C.; no data validation (PID readings with sample results), samples to lab 7/13/94 is about 1 month later (field work began 6/16, samples taken 6/17,28 and 7/13) ? storage during this period, PID readings do not jibe with soil analysis, samples arrive at lab up to 6 degrees C.; Volume II lab results do not jibe with Volume I, etc. In addition, for site #3, tank 7, sampling done 6/17 and 20/94 questionable as no lab data found on 4 samples taken, no data deliverables. Report lacks adequate narrative normally found in site assessments. |

| 5/8/1996 |
Update or Other Action |
(Old R:Base Action Code = RAPR - Remedial Action Plan Review (CS)). Revised CAP by new RPCON proposes installing 1 MW from the former gasoline refueling USTs, site #2, tanks 5 and 6. For site #3, tank 7, proposed no action on the HOT site, as error was made in the site assessment done by another RPCON in 1994. For site #4, tanks 8 and 9, proposed 2 inclined vent wells and 1 MW for this diesel contaminated site. For site #5, tank 10, no action proposed as DRO results indicate levels below ADEC cleanup standards. For site #6, tank 11, proposed 1 inclined vent well, 1 inclined GW MW, 3 vapor monitoring points and in-situ testing. Diesel from the HOT contamination extends to the building foundation and prevented total removal. For site #7, tanks 12 and 13, proposed 2 vent wells and 1 GW MW. |

Update or Other Action |
(Old R:Base Action Code = FI - Field Inspection (General)). Site #2, tanks 5 and 6, are located at entrance to Station and opposite Guard House. Two 5K gallon gasoline USTs supplied gas to employees and Station. USTs were removed and not replaced. USTs were within 50' from Gilmore Creek. RPCON proposes to install 1 MW. Site #3, tank 7, is located ~150' from site #4 (west). 2K gallon HOT removed 6/14/94. This was a "clean" UST removal as DRO levels were below ADEC cleanup levels. For site #4, tanks 8 and 9, cafeteria never established but site known as Alaska Building. Two 5K gallon diesel HOTs removed 6/16-17 and 20/94 with ~112 cubic yards of contaminated soil that was thermally treated. RPCON proposed 1 MW in parking lot near Gilmore Creek and 2 SBs near building. Residual diesel at the foundation. Site #5, tank 10, is bordered by 2 mobile homes used for glacial control. Plans are to possibly close this site as error was made in initial site assessment performed in 1994 by another RPCON. For site #6, tank 11, one 5K gallon diesel HOT removed 6/20/94 with 65 cubic yards of contaminated soil thermally treated. A slough runs next to this maintenance shop. Attention called to pollution practice by personnel dumping paint on ground near slough. Site sits between Gilmore Creek and slough. A new 5K gallon HOT installed in 1994. For site #7, tanks 12 and 13, 2 diesel and gasoline USTs used to fuel vehicles were removed and new USTs installed in 1994. Attention called to practice of washing vehicles and parts on unpaved area near slough. Some form of collection system with oil/water separator suggested. |

Update or Other Action |
Site has been transferred to Anchorage NOAA staff person, Ray Dronenburg for follow-up re-QAPP violations by ESI on S.A. and oversight of CAP by Seattle based RPCON to be conducted summer 1996. |

Long Term Monitoring Established |
Approval this date to remove contaminated soils to desorption unit. No further action needed for remediation of in-situ soils. Three years review of monitor wells by NOAA contractor ANNUALLY with the first sampling to occur 7/15/l997. |
Ray Dronenburg |
| 1/30/1998 |
Update or Other Action |
Nortech reports that tanks are removed or excavated and disposed of and soils are burned. A 3 year monitoring program has been instituted to review potential GW problems. Due to contamination below foundations at sites #4, tanks 8 and 9, Cafeteria Building, and site #6, tank 11, Mini-Tract Building, site recommended for long-term Institutional Control site status. |

Long Term Monitoring Complete |
After three years of groundwater monitoring there were no exceedances of MCLs at any well locations despite residual soil levels of 1100 mg/kg of DRO at site 1, well v01-02, found in 1996 under an existing structure. Any residual contamination does not pose a significant threat to human health due to the lack of an exposure pathway. |

| 2/14/2001 |
Institutional Control Record Established |
In 1996, there were residual soil levels of 1100 mg/kg of DRO at site 1, well v01-02, found under an existing structure. If the structure is removed, additional investigation and possible soil removal should be considered. |

| 2/14/2001 |
Conditional Closure Approved |
In January 2001, the STP assumed management of the site since 11 of 14 tanks involved were regulated USTs. John Carnahan of STP issued a NFA letter to NOAA on 2/14/2001. After three years of groundwater monitoring there were no exceedances of MCLs at any well locations despite residual soil levels of 1100 mg/kg of DRO at site 1, well v01-02, found in 1996 under an existing structure. Any residual contamination does not pose a significant threat to human health due to the lack of an exposure pathway. |
