11/25/2013 Document, Report, or Work plan Review - other Received Site Characterization Work Plan from Ahtna Engineering dated November 12, 2013 Peter Campbell
4/29/2014 Site Characterization Workplan Approved Received a revised work plan for a soils and groundwater investigation at the site. Three soil borings and three monitoring wells are to be installed in an attempt to determine if there is a source of TCE on site that is impacting the Baker Oil Tools drinking water well. The work plan was approved without conditions. Peter Campbell
7/16/2014 Site Characterization Report Approved Reviewed the Nikiski Completions Facility Site Characterization Report, dated July 9, 2014, prepared by Ahtna Engineering. On May 12th through May 16th, 2014 a site characterization was conducted to determine whether TCE detected in the water samples from the groundwater well located at the Nikiski Facility resulted from on-site activities. Areas investigated included the septic leach field and the building drains, corresponding sumps and piping. Soil borings SB-3 and SB-5 were advanced to evaluate the impact in the vicinity of the eastern portion of the facility building piping, where TCE was detected at 40 to 45 feet bgs at concentrations of 0.058 and 0.024 mg/kg. Soil boring SB-4 was advanced to evaluate the impact of the septic leach field, where TCE was detected at 35 to 40 feet bgs at 0.093 mg/kg. Three of the soil borings were constructed into groundwater monitoring wells. Water samples collected from the monitoring well installed in the area of the septic leach field detected TCE groundwater contamination at 0.043 mg/L. Groundwater was measured at 37.85 to 39.47 in measured groundwater monitoring wells. The groundwater measurements in on-site monitoring wells indicated a shallow groundwater gradient flowing to the northwest. No hydrocarbons were encountered. Two separate sump areas located at the paint shop and waste storage areas were investigated by performing a hydrostatic test. Each area consisted of a pair of sumps. Paint shop consisted of an east sump approx. 31.4-gallons and a west sump approx. 42.34-gallons, and the waste storage area consisted of a north sump approx. 101.45-gallons and a south sump approx. 228.27-gallons.

7/17/2014 Document, Report, or Work plan Review - other Letter sent to Baker Oil Tools approving additional monitoring well sampling and the installation of three additional monitoring wells. Peter Campbell
7/30/2014 Document, Report, or Work plan Review - other Review and approve a plan to investigate and remove floor drain piping and a tank associated with the floor drain system. The floor drain piping was inspected with a camera system. It appeared that lines were collapsed and in disrepair. Sampling will be conducted to determine if this system is a source of contamination. Peter Campbell
8/6/2014 Site Visit Four Class five injection wells discovered that had been connected to interior floor drains. The injection well closure will be regulated by the EPA, impacted soil and groundwater will be regulated by ADEC. Peter Campbell
8/18/2014 Document, Report, or Work plan Review - other Received Work Plan Addendum - Nikiski Completions Facility Phase II Removal. The Class V injection wells connected to floor drains from the building are being decommissioned and possible impacts are being investigated. The investigation now includes the EPA Injection Well Program and the State of Alaska Underground Storage Tank (UST) Program as well as the State Contaminated Sites Program. Peter Campbell
9/2/2014 Underground Storage Tank Site Characterization or Assessment Received a UST Post-Closure-Notice for a 1800 gallon tank that was part of an EPA regulated Class five injection well. The tank closure is regulated by the ADEC UST Program. A Site Assessment Report is due by October 20, 2014. Peter Campbell
9/26/2014 Document, Report, or Work plan Review - other Received the August 2014 Groundwater Monitoring Report. TCE was detected in a monitoring well (MW-1) at levels above ADEC cleanup standards, over time. This well is near what appears to be the source area, a network of floor drain sumps. Peter Campbell
10/27/2014 Document, Report, or Work plan Review - other Two injection well systems at the site were removed. Analytical data from the contents of a removed steel oil/water separator/Underground Storage Tank (UST) and from the soil located immediately below the concrete cased injection wells indicate that the source of Trichloroethylene (TCE), tetrachloroethylene (PCE) diesel range organics (DRO) and some elevated metals impact was the injection well systems used to dispose of fluids from the paint shop and wash bay sumps. Residual DRO and chromium impact to soil remains at the site at the southern end of the steel oil/water separator/UST and in soil below the former easterly concrete cased injection well. DRO, PCE, barium, cadmium, chromium, and lead impact is associated with the drainage area located north of the now removed steel oil/water separator/UST. Characterization activities proposed include the installation of a soil boring and a groundwater monitoring well through the location of one of the concrete cased injection wells and one soil boring at the form former southern end of the steel oil/water separator/UST. Additional groundwater monitoring wells will be installed to delineate the dissolve-phase TCE plume identified at the site in previous characterization work. Peter Campbell
