Problems/Comments

Multiple release events have occurred in the same region of this site (one in 1999, another in 2001, and a third on 4 January 2010). Multiple records have been created as Hazard ID: 23316 and Hazard ID 22986. One record has the name "Overfill" in the name, and the other does not (i.e. Holiday Station Store #630 Overfill / Williams Express Store #5030). The first events in 1999 and 2001 occurred when the overfill buckets overflowed. This event was cleaned up, and a closure letter was issued. Soon afterward, a third release event occurred, and the closure letter was rescinded. The third event involved an estimated volume of less than 50 gallons of gasoline, which was released when trenching activities ruptured a fuel line during facility upgrades on 4 January 2010. The release occurred over a geotextile liner, which remained intact throughout the excavation and remediation process. Approximately 5 cubic yards of contaminated soil were removed from the source area during the initial response. Soil, groundwater, and vapor samples were collected on 22 January, 28 April, and 7 July 2010. Groundwater was sampled from nearby and downgradient monitoring wells and did not contain detectable concentrations of COCs. Nevertheless, the pre-existing Vapor Extraction Air Injection System (VEAIS) was reactivated on 22 January 2010. Field screening measurements of air quality had stabilized at background levels by March 2010, and the VEAIS was subsequently deactivated on 4 June 2010.

Keather McLoone
1/24/2008	Update or Other Action	During 2007 annual meeting, previous project manager discussed approaching DEC PM for the adjacent Chevron site regarding the sampling of B2MW, B5MW, and B6MW. Email on this date, gave approval to Holiday to discontinue sampling at these wells provided that access would not be limited to Chevron so that they could sample them. As of November 2008, not sure if Chevron has/will sample these wells although administrative file for that report acknowledges the groundwater gradient from that site to the Holiday site.	Keather McLoone
7/17/2008	Document, Report, or Work plan Review - other	Received 2007 report electronically. Review included laboratory review checklist. VES system has not been operational since December 2007 after operating in pulse mode since September 2007. S&W recommends that Holiday petition to discontinue sampling at B1MW and B3MW. ADEC approved the discontinuation of sampling at these two wells in an email sent on 09/05/08. An early November 2007 vapor sample appears to be an anomoly and was analyzed past TO-17 holding time.	Keather McLoone
4/8/2009	Update or Other Action	Receipt of 2008 lab data, draft data table, and draft laboratory review checklist. Discussion with other DEC staff about future monitoring of 3 onsite wells by Chevron and site status. Email sent on 4/16 to S&W to indicate that ADEC believes that this site is a candidate for conditional closure.	Keather McLoone
4/28/2009	Update or Other Action	Letter from Robert Weimer (PM for Chevron Site 9-9014) stating "based on available data it appears that contamination from the above referenced Chevron site is impacting three monitoring wells (B2MW, B5MW, and B6MW) located on the Holiday's site across Spenard Road. The Alaska Department of Environmental Conservation, Contaminated Site Program requests that you have those three monitoring wells (B2MW, B5MW, and B6MW) sampled, until further notice for BTEX and GRO, along with the semi-annual groundwater monitoring events at the Chevron Site 9-9014."	Keather McLoone
6/8/2009	Document, Report, or Work plan Review - other	Review of April and October Groundwater Monitoring report. During January 2008 schedule visit for VES monitoring, the VES was found to be nonoperational and a decision was made to leave the system off pending 2008 groundwater monitoring results. Four wells were sampled in April and two in October (the other 2 were removed from the sampling program). The April sample from B8MW contained benzene at 0.00803 mg/L which was the only result above Table C. Shannon & Wilson plans to submit a petition for Corrective Action Complete with ICs. Laboratory data and laboratory review checklist was reviewed in April as it was requested then to review decision to discontinue monitoring of groundwater by Holiday (Chevron will continue at 3 wells) and whether site could be considered a candidate for a closure with ICs decision.	Keather McLoone
7/1/2009	Update or Other Action	Received Petition for Cleanup Complete - Institutional Controls.	Keather McLoone
10/21/2009	Site Visit	Site visit to see if 1805 McKinley Ave has an occupied home - yes.	Keather McLoone
11/5/2009	Update or Other Action	Several attempts were made to contact the owner of downgradient property located at 1805 McKinley Avenue with private drinking water well according to online Muni information, call to Muni onsite department, and AWWU. These contacts did not eliminate the possibility of a private well remaining at that property. Several messages were left for the property owner but not returned. This information was passed on the PM for the Chevron 9014 site.	Keather McLoone
1/5/2010	Site Visit	A site visit was conducted to observe site conditions due to recent release which occurred during trenching for a power conduit.	Keather McLoone
2/4/2010	Update or Other Action	Due to the January 4, 2010 release event, soil contamination was found down to the smear zone (2/3/10 email comm.). Since the agreement dated 12/4/09 to close this site with ICs (CC-IC) was not signed, ADEC has determined that this site should remain in active status and a letter was sent on this date to rescind the CC-IC closure letter. Future reporting of the new event (from 4 Jan 2010) will be conducted under the same file number, with hazard ID #22986.	Keather McLoone
2/23/2010	Update or Other Action	A letter was sent to the owner of 1805 McKinley Ave asking them to contact ADEC CSP regarding the potential for future sampling of the apparent drinking water well on this downgradient property.	Keather McLoone
3/12/2010	Update or Other Action	After reviewing file for additional information regarding which drinking water wells had been sampled in the past in this area either by Holiday or by Chevron, ADEC left a voicemail message for the owner of the home at 1805 McKinley Avenue. As of today's date (3/24/10) have not received a return phone call, nor had past calls been returned. This individual had phoned ADEC on 3/9/2010 in response to receipt of letter sent by ADEC. Since messages have not been returned historically, ADEC will wait to be contacted once again by this individual. The residence directly next door to the east also has a private drinking water well which had been sampled nearly 10 years ago but results were below Table C.	Keather McLoone
6/4/2010	Update or Other Action	S&W requested approval to shutoff VEAIS system for a rebound test. System was restarted after January 2010 release. Groundwater samples were also collected in January and May of this year from select wells nearest source and were nondetect. VEAIS data has shown a decrease in recovery since being restarted. Anticipate that all this information will be reported in an upcoming report and the earlier CC with ICs decision revisited for this facility.	Keather McLoone
1/6/2011	Document, Report, or Work plan Review - other	Date of receipt of Release Investigation report. On January 4, 2010 - about 5 cubic yards of pea gravel was removed from above a lined, 6 ft by 6 ft area up to 4 ft bgs during the initial spill response. Field screening and analytical results showed that GRO, benzene, toluene, ethylbenzene and xylene contamination remained. On January 18, 2010, a boring was advanced about 3 from the most recent excavation to help assess the vertical extent of contamination. Elevated screening results were obtained from throughtout the vertical profile and a soil sample selected from just above the groundwater interface which contained 2.53 mg/kg benzene. Also on January 18, during completion of the electrical trench (whose earlier advancement caused this more recent release), additional screening was performed but no analytical samples were collected. Remediation system was restarted on January 22, 2010 with one air injection well and four VES wells operating with monitoring and analytical samples collected until the system was shut down on June 2010 and restarted on July 7 for a final sampling event. The system is not currently operating. Groundwater samples were collected from B3MW, B7MW, and B8MW on January 22; from B1MW, B7MW, and B8MW on April 28; and from B3MW, B7MW, and B8MW on July 7 to assess whether the remediation system was needed to prvent migration of contamination to groundwater. Report comment letter stated "More data is needed to delineate the nature and extent of this release as is required by 18 AAC 78.235 (a)(1) and as is needed for exposure pahtway evaluation...." Requested to be notified within 30 days of the January 26, 2011 letter but as of 7/25/2011 still have not had a response.	Keather McLoone
7/26/2011	Document, Report, or Work plan Review - other	Date of receipt of Work Plan for Additional Soil and Groundwater Sampling. Holiday plans to install a single additional monitoring well on the downgradient side of the former trench excavation. Two soil samples will also be analyzed. ADEC conditionally approved the plan.

11/13/2012	Site Visit	Conducted a site visit to observe decommissioning of monitoring wells. All monitoring wells except B2MW, B5MW, B6MW, and B7MW were decommissioned. B7MW was originally planned to have been decommissioned, but it was determined to be part of the VES. Therefore, Shannon & Wilson will address this issue separately when it decommissions the remediation system.	Richard Bernhardt
12/5/2012	Meeting or Teleconference Held	Met with Holiday (Bruce Anthony) and his consultants from Shannon and Wilson (Matt Hemry and Dan McMahon) to discuss progress toward terms of site closure. S&W requested an extension to decommission monitoring well B7MW because of difficulties described in the 13 Nov entry. An extension was granted, and the well will be decommissioned as soon as possible. (HSS 602, 606, WES #5004, and WES #5021 were also discussed).	Richard Bernhardt

Received 2007 report electronically. Review included laboratory review checklist. VES system has not been operational since December 2007 after operating in pulse mode since September 2007. S&W recommends that Holiday petition to discontinue sampling at B1MW and B3MW. ADEC approved the discontinuation of sampling at these two wells in an email sent on 09/05/08. An early November 2007 vapor sample appears to be an anomoly and was analyzed past TO-17 holding time.

Update or Other Action

Letter from Robert Weimer (PM for Chevron Site 9-9014) stating "based on available data it appears that contamination from the above referenced Chevron site is impacting three monitoring wells (B2MW, B5MW, and B6MW) located on the Holiday's site across Spenard Road. The Alaska Department of Environmental Conservation, Contaminated Site Program requests that you have those three monitoring wells (B2MW, B5MW, and B6MW) sampled, until further notice for BTEX and GRO, along with the semi-annual groundwater monitoring events at the Chevron Site 9-9014."

Document, Report, or Work plan Review - other

Review of April and October Groundwater Monitoring report. During January 2008 schedule visit for VES monitoring, the VES was found to be nonoperational and a decision was made to leave the system off pending 2008 groundwater monitoring results. Four wells were sampled in April and two in October (the other 2 were removed from the sampling program). The April sample from B8MW contained benzene at 0.00803 mg/L which was the only result above Table C. Shannon & Wilson plans to submit a petition for Corrective Action Complete with ICs. Laboratory data and laboratory review checklist was reviewed in April as it was requested then to review decision to discontinue monitoring of groundwater by Holiday (Chevron will continue at 3 wells) and whether site could be considered a candidate for a closure with ICs decision.

Update or Other Action

Several attempts were made to contact the owner of downgradient property located at 1805 McKinley Avenue with private drinking water well according to online Muni information, call to Muni onsite department, and AWWU. These contacts did not eliminate the possibility of a private well remaining at that property. Several messages were left for the property owner but not returned. This information was passed on the PM for the Chevron 9014 site.

2/4/2010

Update or Other Action

Due to the January 4, 2010 release event, soil contamination was found down to the smear zone (2/3/10 email comm.). Since the agreement dated 12/4/09 to close this site with ICs (CC-IC) was not signed, ADEC has determined that this site should remain in active status and a letter was sent on this date to rescind the CC-IC closure letter. Future reporting of the new event (from 4 Jan 2010) will be conducted under the same file number, with hazard ID #22986.

Keather McLoone

2/23/2010

Update or Other Action

A letter was sent to the owner of 1805 McKinley Ave asking them to contact ADEC CSP regarding the potential for future sampling of the apparent drinking water well on this downgradient property.

3/12/2010

Update or Other Action

After reviewing file for additional information regarding which drinking water wells had been sampled in the past in this area either by Holiday or by Chevron, ADEC left a voicemail message for the owner of the home at 1805 McKinley Avenue. As of today's date (3/24/10) have not received a return phone call, nor had past calls been returned. This individual had phoned ADEC on 3/9/2010 in response to receipt of letter sent by ADEC. Since messages have not been returned historically, ADEC will wait to be contacted once again by this individual. The residence directly next door to the east also has a private drinking water well which had been sampled nearly 10 years ago but results were below Table C.

6/4/2010

Update or Other Action

S&W requested approval to shutoff VEAIS system for a rebound test. System was restarted after January 2010 release. Groundwater samples were also collected in January and May of this year from select wells nearest source and were nondetect. VEAIS data has shown a decrease in recovery since being restarted. Anticipate that all this information will be reported in an upcoming report and the earlier CC with ICs decision revisited for this facility.

Document, Report, or Work plan Review - other

Date of receipt of Release Investigation report. On January 4, 2010 - about 5 cubic yards of pea gravel was removed from above a lined, 6 ft by 6 ft area up to 4 ft bgs during the initial spill response. Field screening and analytical results showed that GRO, benzene, toluene, ethylbenzene and xylene contamination remained. On January 18, 2010, a boring was advanced about 3 from the most recent excavation to help assess the vertical extent of contamination. Elevated screening results were obtained from throughtout the vertical profile and a soil sample selected from just above the groundwater interface which contained 2.53 mg/kg benzene. Also on January 18, during completion of the electrical trench (whose earlier advancement caused this more recent release), additional screening was performed but no analytical samples were collected. Remediation system was restarted on January 22, 2010 with one air injection well and four VES wells operating with monitoring and analytical samples collected until the system was shut down on June 2010 and restarted on July 7 for a final sampling event. The system is not currently operating. Groundwater samples were collected from B3MW, B7MW, and B8MW on January 22; from B1MW, B7MW, and B8MW on April 28; and from B3MW, B7MW, and B8MW on July 7 to assess whether the remediation system was needed to prvent migration of contamination to groundwater. Report comment letter stated "More data is needed to delineate the nature and extent of this release as is required by 18 AAC 78.235 (a)(1) and as is needed for exposure pahtway evaluation...." Requested to be notified within 30 days of the January 26, 2011 letter but as of 7/25/2011 still have not had a response.

Date of receipt of report entitled Additional Characterization, Holiday Station Store 630. A single boring was advanced and completed as a monitoring well (B10MW) in the apparent downgradient direction from the January 2010 release. One soil sample was collected from the 3-5 foot interval which was the interval with the highest PID reading. A second soil sample was collected near the groundwater interface. B3MW, B7MW, B8MW, and B10MW were sampled. There were no exceedance of criteria in either the soil or the groundwater samples. An additional round of groundwater sampling during the spring at these four wells will be requested.
