11/8/2004 Institutional Control Record Established ADEC recognizes that the source areas of contamination have been removed from the site but there is residual contamination remaining. An institutional control (IC) in the form of a database entry will be placed in the Contaminated Sites database to document that groundwater contamination remains at the site above applicable cleanup levels. Eric Henry
11/8/2004 Conditional Closure Approved Fall 2004 report verifies a decreasing trend exists for benzene in groundwater (GW) at site #1 and soil is below cleanup levels. Site #2 has metals in soil above cleanup levels but they are consistent with levels that are naturally occurring in this area. Dissolved metals are below cleanup levels at site #2. The information provided to date indicates that soil contamination above 18 AAC 75.341 Method 2 (migration to GW) cleanup levels is still present and there are low levels of benzene detected in the GW above the 18 AAC 75.345 Table C cleanup levels. The benzene (in UST #1) and arsenic and chromium (in UST #2) remain in soil at levels above the established cleanup levels for this site. The arsenic and chromium concentrations are within background levels typically found in the Anchorage region according to the U.S. Geological Survey (1988). The GW data indicates benzene is stable or decreasing in concentration. ADEC recognizes that the source areas of contamination have been removed from the site but there is residual contamination remaining. The migration to GW pathway may be exceeded but the low level impacts to GW are expected to naturally attenuate over time. The shallow GW at this site has been impacted but isn't considered a drinking water source. The no further remedial action decision for this site is subject to the following conditions: 1. The GW shall be monitored on an annual basis from UST Site #1 for BTEX compounds. The sampling shall occur in the fall (e.g. September) and continue until 18 AAC 75.345 Table C cleanup levels are consistently achieved for all compounds. The sampling shall to be performed in accordance to the Final Release Investigation Workplan that was approved by ADEC on August 26, 2002. 2. The transport, treatment and/or disposal of soil and GW from the site requires prior ADEC approval in accordance with 18 AAC 78.600(h). 3. Any proposal to install a groundwater well at this site requires approval from DEC. Eric Henry

7/9/2013 Institutional Control Compliance Review IC compliance review conducted. Reinvestigate the 2004 closure requirement of additional groundwater monitoring has never been done with the updated 2009 closure policy in mind. Removed groundwater monitoring requirement due to the amount of time since closure and that the contaminant concentrations in the groundwater in 2004 were barely above the Table C Groundwater cleanup levels. Evonne Reese
12/9/2015 Institutional Control Compliance Review IC compliance review conducted, scheduled to send an IC reminder letter to the current property owner in the near future, and also scheduled periodic reviews every three years. Evonne Reese
