We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.

Problems/Comments

Gasoline hydrocarbon fraction and benzene, toluene, ethylbenzene and xylene compound contamination remained in soil excavation following underground storage tank (UST) closure on 3/26/1999. ADEC letter dated 6/14/1999 approved alternative cleanup levels and no further cleanup action due to shallow depth to bedrock and no groundwater encountered in the excavation. Water well on-site was used to confirm no groundwater or appearance of tidal influence during periods of 17 foot high tides. Contaminated material at off-site location is under passive natural attenuation treatment.

3/26/1999 Leaking Underground Storage Tank Release Confirmed - Petroleum LUST Site created in CSP for source area ID 77567 (Added by System) Former Staff
3/26/1999 Leaking Underground Storage Tank Cleanup Initiated - Petroleum 150 cubic yards of soil contaminated with petroleum removed and stockpiled on site. Former Staff

6/14/1999 Cleanup Level(s) Approved Avi Fennimore reported that they observed no groundwater in the monitoring well located on-site at midnight June 11, 1999 (time of 16.0 ft high tide in Wrangell). Based on this, on the observations by consultant of no groundwater in the excavation for several days, and bedrock at the bottom of the excavation, a waiver from the migration to groundwater cleanup level was granted (no groundwater to contaminate) on 6/14/99 via letter, and no further action will be needed to be taken at the site. However, the 150 cuyd stockpile will still require remediation to attain a Table 2 cleanup level (offsite disposal). Former Staff

1/3/2003 Update or Other Action Request for information concerning site remediation plan for contaminated soil stockpile sent to RP. Copied to Jnu G:SPAR/CSites/SE Field OPS/SE Sites/ Fennimore Service Center/ ReQuest Fennimore SC Bruce Wanstall
7/8/2004 Streamlined Cleanup Program Site conditions match criteria for acceptance into Streamlined Cleanup Program. Bruce Wanstall
7/22/2004 Site Visit ADEC recorded GPS while observing and photographing contaminated soil stockpile site on the Zimovia Hwy material site. Results are recorded as N 56.42810 latitude and W -132.35597 longitude. Exposed bedrock on which the soil was land spread did not appear to be influenced by ground water. Ponded surface water did not exhibit sheen. Bruce Wanstall
12/2/2004 Update or Other Action Cross referenced the Fennimore Service Center USTs and soil stockpile location south on Zimovia Highway with public complaint from neighbor to the Kadin Corp property. The complaint about hazardous waste disposal and noxious burning in fall 2001 was reportedly resolved by property owner. No further complaints have been recieved by the DEC. Soil stockpile sampling plan is still in draft status. Bruce Wanstall

1/14/2009 Exposure Tracking Model Ranking Pathway evaluation update scoring for source area 77567 using site assessment data and current information. Exposure pathways are either controlled, incomplete or de minimis for the both the facility property and the contaminated soil land spread site. Dermal contact and inhalation petroleum cleanup levels for GRO and BTEX contaminants of concern are established for the factility where ground water is not present. All residual soil contamination related to the subsurface release cleanup in 1999 is likely attenuated to concentrations protective of surface water and ground water. This determination does not describe environmental conditions pertaining to subsequent commercial activity at the sites since that time. Bruce Wanstall
1/14/2009 Cleanup Complete Determination Issued The sources of contamination at the Fennimore Service Center facility were removed from the site. The site assessment data has documented that residual soil impacts meet the established cleanup levels and the off-site contaminated soil stockpile has attenuated to an acceptable condition. As a result, ADEC will not require any further cleanup actions and the site is approved for closure status. Although a Corrective Action Complete determination has been granted, ADEC approval is required for off-site disposal of soil in accordance with 18 AAC 78.600(h). It should be noted that movement or use of potentially contaminated soil in a manner that results in a violation of 18 AAC 70 water quality standards is unlawful. This determination is in accordance with 18 ACC 78.276(f) and does not preclude ADEC from requiring additional assessment or cleanup action if future information indicates that this site may pose a current or future unacceptable risk to human health or the environment.

3/9/2010 Document, Report, or Work plan Review - other DEC has evaluated the Contingency Plan for the Wrangell Road and Utility Improvement Project by DOWL HKM and approves the Plan in accordance with 18 AAC 75.325--75.335 and 18 AAC 78.230 - 78.280. The objective of the Plan is to be prepared for obstacles that could impede the progress of the project and the purpose of the Plan is for contractors to follow the decision matrix and properly inform the applicable regulatory agencies when the Plan is implemented. Bruce Wanstall
3/13/2012 Update or Other Action Contractors excavating for a sewer service in the Wrangell Road Improvements Project on Front Street have found abandoned fuel tanks in the right of way. Tanks include several regulated tanks that were historically closed in place with DEC approval and other various historically used fuel/heating oil tanks. This month another flattened empty abandoned tank with no contents was removed and taken to the Wrangell landfill as scrap. DEC has been kept informed of these encounters in accordance with the approved 2009 DOWL HKM Wrangell Road and Utilities Project Contingency Plan/ Corrective Action Plan. Bruce Wanstall
10/31/2014 Exposure Tracking Model Ranking A new updated ranking with ETM has been completed for source area 77567 UST. Bruce Wanstall

Contaminant Information

Name Level Description Media Comments
Benzene Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation Soil After (10) years volatile benzene at 3.6 mg/kg is unlikely to be detectable in either land spread surface soil or soil trapped under utilities and buidlings at the site; ground water is not present.
Ethylbenzene Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation Soil After (10) years volatile ethylbenzene at 7.1 mg/kg is unlikely to be detectable in either land spread surface soil or soil trapped under utilities and buidlings at the site; ground water is not present.
GRO Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation Soil Volatile petroleum fraction concentrations began declining as soon as soil was removed to the surface air. Residual GRO in subsurface soil reached 300 mg/kg and in stockpile soil GRO reached 1,100 mg/kg. After (10) years it is doubtful GRO could be detected in either surface or subsurface soil.
