1/29/2007 Conditional Closure Approved Based on the information presented to date, ADEC has determined that diesel fuel contamination remaining at this site does not pose an unacceptable risk to human health or the environment. There is no further remedial action required to address the residual contamination and the site will be conditionally closed. Todd Blessing
1/29/2007 Institutional Control Record Established Groundwater shall be monitored in accordance with 18 AAC 75.345(h) to ensure contamination is decreasing. A groundwater monitor plan shall be submitted for ADEC review and approval. Any proposal to transport soil or groundwater from this property requires ADEC approval in accordance with 18 AAC 78.274(b). Todd Blessing
5/15/2007 Update or Other Action DEC reviewed and approved a work plan to conduct a groundwater monitoring event. This work plan was constructed by URS, dated May 9, 2007, and was received on May 10, 2007. Within the work plan, URS proposes to do the following: 1.Determine groundwater elevation of all on-site monitor wells in order to evaluate groundwater flow characteristics. 2.Collect groundwater samples from all on-site wells to be analyzed for GRO, DRO, and BTEX. 3.Evaluate the quality of the analytical data by completing DEC's laboratory data review checklist. 4.Complete a Groundwater Monitoring Report. Todd Blessing
10/12/2007 Update or Other Action Contaminated Sites (CS) staff reviewed a Well Installation and Groundwater Monitoring Plan. The plan was prepared by URS and was received by this office on October 9, 2007. It outlines the procedures URS will employ to install a new groundwater monitor well and collect soil and groundwater samples to be analyzed for contaminants of concern at a DEC approved laboratory. Todd Blessing
7/11/2008 Update or Other Action DEC staff reviewed a well installation and groundwater monitoring report titled "Well Installation and Groundwater Monitoring Federal Express ANCR Facility." The report was prepared by URS, dated May 30, 2008 and received at DEC's Anchorage office on June 05, 2008. Soil and groundwater analytical results were discussed for a March 2008 groundwater sampling event and a June 2007 monitor well installation event. A new monitor well was installed upgradient (i.e. northwest) of monitor well MW-5. Soil samples were collected at 12 feet below ground surface to be analyzed for contaminants of concern (COCs). No COC's were detected at levels that exceed DEC cleanup criteria. Groundwater samples were collected from each well and analyzed for GRO/BTEX and DRO. DRO was the only analyte detected in groundwater samples that exceeded DEC cleanup criteria. DRO levels ranged from nondetect to 46.5 mg/L. A review of laboratory data chromatograms suggests that de-icer fluid is interfering with the measurement of DRO and therefore, the levels of DRO in groundwater are questionable. DEC staff issued a letter on July 11, 2008 requesting that Fed-EX's consultant evaluate the levels of glycol in future groundwater monitoring events. Todd Blessing
11/2/2009 Site Characterization Report Approved DEC staff reviewed URS’ “Groundwater Monitoring Federal Express ANCR Facility 6050 Rockwell Avenue, Ted Stevens Anchorage International Airport, Anchorage International Airport", dated October 26, 2009. URS documented the results of an August 2009 groundwater monitoring event at the Federal Express ANCR Facility. No free phase fuel product was observed in any of the monitoring wells. Groundwater flow was determined to flow southeast and was consistent with prior groundwater monitoring events. The groundwater table was approximately 1 half a foot lower compared to the March 2008 groundwater monitoring event. In general, the levels of dissolved gasoline constituents increased in the majority of wells and the levels of dissolved diesel constituents decreased. URS postulated that an upgradient source of weathered gasoline was impacting the site. Todd Blessing
9/22/2011 Site Characterization Report Approved DEC staff reviewed URS' "Report Groundwater Monitoring Federal Express ANCA (Warehouse) 3444 West International Airport Road Anchorage, Alaska". This report documented the annual sampling and analysis of groundwater from wells FE-1 through FE-4. Elevated levels of benzene were detected in FE-1, FE-2, and FE-4; elevated levels of DRO were detected in FE-2 and FE-4; and elevated levels of GRO were detected in FE-4. These results are similar to last years event, and suggest a source of contamination north of the site that is impacting groundwater. Todd Blessing
9/14/2012 Institutional Control Record Removed Following a review of Brown and Caldwell's "Field Activities Report - Groundwater Sampling Federal Express ANCR Facility 6050 Rockwell Avenue", staff has determineed that long term groundwater monitoring is no longer required. Groundwater monitoring data the past four years suggests the groundwater contaminant plume is stable and not increasing. Furthermore, the groundwater data suggests that the primary source of contamination is upgradient of the former leaking underground storage tank. Todd Blessing
