1/28/2008 Cleanup Complete Determination Issued Site Closure and Record of Decision (ROD) issued. Site closure granted based on determination that soil and groundwater at the site meet ADEC cleanup levels for soil under 18 AAC 75.341 Method 2 Tables B1 and B2, and for groundwater under 18 AAC 75.345, Table C. Rich Sundet
11/23/2010 Site Reopened On 11/23/10, S&W provided a report dated 11/5/10 to Udelhoven Oilfield Support Systems, Inc. a leasee of a portion of the site and potential leasee of more of the property. Site visits were performed on 9/15 and further assessment work was performed on 9/22, 10/12 and 10/13/2010 consisting of the collection/analysis of surface soil samples based upon field screening and visual observations. Eight analytical samples were collected from visually stained surface soils and analyzed for DRO, RRO, GRO, BTEX and the eight RCRA metals. Seven samples were collected from the western portion of the property and analyzed for the same analytes except BTEX was exchanged for VOC analysis. One water sample was collected from the crawl space in the on site building for the same analytes as collected from the western portion of the property. The report showed that the analytes above cleanup levels that their maximum levels of detection were: PCE at 70.7 mg/kg, chromium at 68.2 mg/kg, arsenic at 12.6 mg/kg, RRO at 106,000 mg/kg, and DRO at 64,800 mg/kg J qualifier. In the test pit only RRO exceeded its Table C level at 1.85 mg/L. Rich Sundet
11/23/2010 Meeting or Teleconference Held On 11/23/10, DEC met with the property owner (Miles Schlosberg), a current leaseholder Mark Larson, realtor Karl Kuhn, and S&Ws Matt Hemry and Jessica Busey. Discussion focused upon the recent S&W report that Matt Hemry provided to DEC earlier on 11/23 that showed recent sampling of elevated chromium, RRO, DRO and PCE in soil, and RRO in groundwater in a test pit. Miles requested that a plan be submitted for the next phase (further characterization and perhaps skimming off surface contamination and dispose off site) in April. DEC agreed based upon that there does not appear to be an immediate human health or ecological risk. The recent assessment work was paid for by a group (Udelhoven) who recently began leasing the eastern portion of the property. Mark Larson's company is currently leasing the western portion of the property. Rich Sundet
4/15/2011 Document, Report, or Work plan Review - other ADEC conditional approval letter and information request issued for the site characterization work plan dated March 29, 2011, prepared by Shannon & Wilson Inc.

7/28/2011 Update or Other Action Received "Site Characterization...July 2011" report received 7/28/2011. The report documents work done in April 2011. Eileen Olson
8/17/2011 Meeting or Teleconference Held Staff met with consultant representative for Shannon & Wilson and with property owner (ActiveSpace LLC) to go over results of report submitted 7/28/2011. Eileen Olson
9/16/2011 Update or Other Action ADEC received a "Work Plan for Soil Removal Action" dated Sept. 16, 2011 and prepared by Shannon & Wilson, and that entails excavation of select areas of the site but does not address all areas of surface staining documented at the site. Eileen Olson
10/4/2011 Site Visit Site visit; ADEC staff met with consultant, owner's representative, and former tenant Udelhoven representatives. Eileen Olson
10/7/2011 Site Characterization Workplan Approved ADEC conditionally approved in an email a limited version of the "Work Plan for Soil Removal Action" dated September 16, 2011; the limited version was proposed in an email from consultant Shannon & Wilson sent October 7, 2011 at 12:36 p.m. and entails excavating PCE-contaminated soil, with the understanding that ASR cannot treat PCE-contaminated soil and ADEC must approve of an alternative treatment method. Eileen Olson
10/28/2011 Meeting or Teleconference Held Staff met with owner's legal representatives and environmental consultants to discuss outstanding issues at the site including whether additional investigation of groundwater, stained surface soil and floor drains is required. Eileen Olson
12/29/2011 Update or Other Action ADEC received "Summary of Groundwater Conditions" report prepared by Shannon & Wilson dated December 29, 2011 (supplementary information was submitted by email on February 24,2012). Eileen Olson
5/31/2012 Document, Report, or Work plan Review - other ADEC letter issued with subject line "Request for groundwater investigation." Request was made based on a review of the file including the "Summary of Groundwater Conditions" document prepared by Shannon & Wilson dated December 29, 2011 with supplementary information submitted by email on February 24,2012. Additional investigation is required to complete site characterization, including determining whether groundwater is or has been a contaminant transport mechanism at the site. Eileen Olson
6/1/2012 Potentially Responsible Party/State Interest Letter ADEC ltr to owner "Notification of ADEC Cost Recovery Requirements". Eileen Olson
6/5/2012 Meeting or Teleconference Held ADEC staff met with consultant to discuss requirements of May 31, 2012 letter requesting groundwater investigation. Consultant requested that ADEC provide information regarding communications with EPA's Underground Injection Control (UIC) program regarding floor drains. ADEC checked with EPA; EPA will communicate directly with consultant as owner's representative. Consultant recommended and ADEC did not object to plan to initially place one well in the PCE-contaminated southwest area of the site to determine groundwater status before installing additional wells requested by ADEC. Eileen Olson
6/6/2012 Update or Other Action ADEC followed up 6/5/2012 meeting by providing current consultant with file references regarding the groundwater depth at the site based on previous investigations. For example a 1992 report by consultant JMM on file includes three monitoring wells placed in the southwest area of the site with groundwater present in all of the wells at about 12.5 feet bgs. A 1998 report by consultant ESL also noted groundwater was encountered about 12.5 feet bgs. Eileen Olson
6/28/2012 Document, Report, or Work plan Review - other ADEC conditionally approved the "Work Plan Addendum for Monitoring Well Installation" dated June 15, 2012 and submitted on June 20, 2012. The plan proposes to install a single monitoring well in the southwest corner of the site close to the location of soil samples containing PCE above cleanup levels. ADEC conditions include placing the well 5-10 feet in the presumed downgradient direction from the location of surface sample SS3, which had a reported concentration of 70.7 mg/kg PCE during sampling in 2010; re-establishing the location of surface sample SS3 using the swing tie measurements recorded in the 2010 field notes; and placing the monitoring well screened interval from a depth of 5 to 20 feet below the ground surface to intercept shallow groundwater present in the area at depths varying from 4 to 12 feet below ground surface. Eileen Olson
10/16/2012 Update or Other Action ADEC received a report and a work plan prepared by S&W. The report is the "Monitoring Well Installation and Groundwater Sampling" report dated Oct. 14, 2012 that reports the results of August 9 and 10, 2012 monitoring well installation and groundwater sampling. The report notes that the depth to groundwater measured at the time of sampling (8.18 feet bgs) was over 5 feet higher than the top of the well screen and therefore the groundwater analytical results may not be representative of the groundwater formation at approximately 8 feet bgs. The plan that was submitted on this date is titled "Work Plan Addendum for Soil Removal Action and Monitoring Well Installation" dated October 15, 2012. Eileen Olson
10/29/2012 Document, Report, or Work plan Review - other ADEC approved by email the "Work Plan Addendum" dated Oct 15, 2012 proposing the installation of one monitoring well. The well will be placed in the presumed downgradient direction from the location of PCE concentrations above soil cleanup levels in the southwest corner of the site. The plan is an addendum to the approved "Work Plan for Soil Removal Action" dated Sept. 16, 2011. The addendum was approved with the condition that ADEC staff are notified no later than the business day preceding work at the site, and kept apprised of any schedule changes so that staff may have the opportunity to observe site work. Eileen Olson
11/2/2012 Update or Other Action ADEC staff was informed by consultant that work scheduled for fall 2013 under the plan approved on 10/29/2012 would be postponed until the next field season. Eileen Olson
6/19/2013 Update or Other Action Consultant S&W informed staff that a monitoring well will be installed on June 20, 2013 near the northeast corner of the site to investigate groundwater contamination at the site in accordance with S&W's work plan dated October 15, 2012, with the modification that the well will be placed ~10 feet from the planned location to avoid utilities.

11/18/2013 Document, Report, or Work plan Review - other A Soil Removal Action and Groundwater Monitoring Well Installation report, dated November 13, 2013, was received by the DEC on this date. Field activities consisted of advancing one soil boring and installing one groundwater monitoring well on the northeast portion of the lot, excavating contaminated material on the southwest portion of the lot (including PCE), and constructing a biocell for the removed contaminated soil. Soil samples collected from the soil boring and excavation, and water samples collected from the monitoring well were analyzed for DRO and RRO. Additionally, the samples collected from the excavation were analyzed for VOCs. The soil samples collected from the biocell were analyzed for nitrates, potassium, phosphorous, and alkalinity. The groundwater sample exhibited a concentration of DRO at 2.52 mg/L and RRO 1.82 mg/L; both of which exceed their approved ADEC cleanup levels. It was suspected that biogenic interference contributed to the elevated DRO and RRO in the groundwater. As such, the groundwater samples were re-run with silica gel and both DRO and RRO were not detected above ADEC cleanup levels. Analytical samples collected from the base and sidewall of the excavation did not exhibit any constituent concentrations that exceeded the ADEC cleanup criteria. Joshua Barsis

1/24/2014 Meeting or Teleconference Held DEC met with Shannon and Wilson, Inc. on this day to discuss the groundwater conditions at this site. Two main topics were discussed during the meeting; namely, biogenic contribution to the groundwater contamination and the potential for a perched aquifer at the site. Joshua Barsis
5/21/2014 Site Visit The Contaminated Sites Program (CSP) performed a site visit on this day. The CSP observed the decommissioning of two Monitoring Wells (B7MW and B8MW). Additionally, the CSP observed a representative of S&W screen and sample the onsite bio-pile. Five separate holes were advanced within the pile ranging from roughly 24-inches to 36-inches below ground surface (bgs). Soil was collected from the base of each hole and field screened using a photoionization detector (PID). Based on the field screening results, three analytical soil samples (including a duplicate), were collected from the two holes that exhibited the highest field screening results. Joshua Barsis
7/2/2014 Document, Report, or Work plan Review - other On this day, the ADEC received the Monitoring Well Decommissioning and Biopile Sampling report, dated June 25, 2014. On May 21, 2014, Monitoring Wells B7MW and B8MW were removed from the ground and decommissioned. Additionally, the biopile was sampled for DRO, RRO, and VOCs. Both RRO and PCE were detected in all soil samples; however, at concentrations below the ADEC cleanup criteria. Joshua Barsis
