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

Dissolved fuel constituents were found in groundwater while evaluating site in 1987/88. Diesel fuel contamination found to be from former UST on site. Amount of fuel, date(s) of release, extent of contamination, and health impact unknown. USTs were removed in 9/89. Contaminated soil was excavated and stockpiled on site as of 11/4/90. Groundwater contamination known to remain. Contaminated soil from UST excavation spread out at Moose Creek Dam; soil removed and stockpiled at original site on 11/4/89. Hazard ID 736 is a duplicate of this site, and therefore was labeled "non-qualifying" within the database.

12/9/1993 Update or Other Action UPD; Couch: Nothing added to file since NOV issued in March 1990. Former Staff
10/7/2004 Update or Other Action Transferred site from Light to Jaynes Cynthia Pring-Ham
4/6/2011 Document, Report, or Work plan Review - other DEC approved a UVOST Site Investigation Work Plan submitted by the U.S. Army Corps of Engineers. The Work Plan proposes to use Ultraviolet Optical Screening Tool (UVOST) to investigate potential and known release areas from former USTs. The investigation area includes the UST locations associated with DEC File Number 100.26.003 and 100.26.172. Fred Vreeman
2/1/2012 Document, Report, or Work plan Review - other DEC provided review comments for the Draft 2011 UVOST Site Investigation Report, Chena River Lakes Flood Control Project, North Pole, AK, January 2012. Based on the review DEC requested additional temporary well points and/or an up-gradient monitoring well be installed to the north of the contaminant source area in order to verify the groundwater flow direction and to address any groundwater characterization data gaps. Dennis Shepard
3/21/2012 Document, Report, or Work plan Review - other ADEC received the Final 2011 UVOST Site Investigation Report. The report concluded that two areas are impacted by DRO contamination in soil above Method two cleanup levels. One area on the northwest corner of the project office is estimated to contain 460 cubic yards of weathered arctic grade diesel (the report states that the contamination is likely a result of former military operations at the site Nike Site Tare). A smaller area was estimated to contain 55 cubic yards of DRO contaminated soil. The report recomends further evaluation/site characterization prior to a removal action. The report also concludes that groundwater at the site should be further evaluated. One of five groundwater samples encountered DRO contamination above the Table C cleanup level. No down-gradient groundwater samples have been collected. Installation of permanent monitoring wells were recomended for the site. Dennis Shepard

5/14/2015 Update or Other Action DEC Staff contacted Andrea Elconin of USACE to determine project status. To date, no work schedule has been established. Dennis Shepard
6/2/2015 Update or Other Action USACE provided an update to project status: USACE will issue an Inventory Project Report (INPR) to determine eligibility for the Formerly Used Defense Sites (FUDS) program. It will take several months to prepare that report and make a determination on eligibility. Therefore no cleanup work will occur on this site in 2015. Dennis Shepard
8/7/2015 Document, Report, or Work plan Review - other DEC provided a formal approval for the Final 2011 UVOST Site Investigation Report. Dennis Shepard
8/10/2015 Update or Other Action Site Transferred to Joy Whitsel. Dennis Shepard
12/1/2017 Update or Other Action Hazard ID 736 with the site name "Chena Lakes Nike Site" was determined to be a duplicate of this site (Hazard ID 24156, site name "ACOE - Chena Lakes Nike Site). Hazard ID 736 was therefore deemed "non-qualifying" in ADEC's CS database. Melinda Brunner
12/6/2017 Update or Other Action Teleconference with U.S. Army Corp of Engineers (USACE) project manager to discuss project status. Federal funding requested for additional site characterization by USACE. Melinda Brunner
7/19/2018 Site Characterization Workplan Approved This Sampling and Analysis Plan (SAP) has been prepared for the Pavement Improvements Chena River Lakes Flood Control Project by Travis/Peterson Environmental Consulting, Inc. (TPECI). This SAP outlines the environmental tasks, including field screening and analytical sampling, required to ensure appropriate measures are taken to protect worker health and safety, prevent mixing of potentially contaminated media with uncontaminated media, document any encountered contamination, and ensure compliance with applicable hazardous waste designation, storage, and disposal regulations. Darren Mulkey
4/16/2019 Site Characterization Report Approved The Pavement Improvements Chena Lakes Flood Control Project is separated into four work areas. Areas 1 and 2 are not located within the boundaries of a contaminated site. Area 4 was not awarded. However, Area 3 is located within the boundaries of a contaminated site mapped as Department of Environmental Conservation (DEC) File ACOE – Chena Lakes Nike Site and ACOE – Chena Lakes Flood Control Project (DEC File # 100.26.003 and 100.26.172).Soil screening and analytical sampling confirm that the sidewalls of the contaminated excavation area are clean from a regulatory standpoint. Petroleum, oils, and lubricant (POL) related contamination (naphthalene) remains in the base of the excavation at a concentration that exceeds the DEC Cleanup Level. Darren Mulkey
