Leaking Underground Storage Tank Cleanup Initiated - Petroleum |
Holiday will be assuming responsibility for investigative and remediation activities at all former Williams Express Stores, but legal responsibility is divided by store. Holiday has renumbered their stores as: 5001=601; 5002=602; 5005=605; 5005=605; 5006=606; 5007=607; 5008=608; 5010=610; 5014=614; 5016=616; 5018=618; 5024=624; 5025=625; 5030=630; 5031=631; 5050=650. While Holiday will oversee the work at the former Williams’ stations, these sites remain the responsibility of Williams. The numbers of these sites remain the same: 5003; 5004; 5009; 5012; 5015; 5017; 5021; and 5034. |

Document, Report, or Work plan Review - other |
Received 2006 GW monitoring report. QA/QC conducted. Analytes detected above Table C cleanup levels in B2MW, B5MW, B6MW, and B7MW. The greatest contaminant concentrations are in wells on the west/northwest side of the property, which are apparently being influenced by offsite contamination originating at the Chevron and/or Thrifty Car Rental locations across Spenard Road to the north. |
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. E-mail on this date gave approval to Holiday to discontinue sampling at these wells, provided that access would not be limited to Chevron to 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 |

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 e-mail sent on 9/5/08. an early November 2007 vapor sample appears to ba an anomaly 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 three onsite wells by Chevron and site status. Email sent on 4/16 to S&W to indicate that ADEC believes the 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 that "based on available data, it appears that contamination from the above referenced Chevron site is impacting three monitoring wells (B2MW, B5MW, and ByMW) located on Holiday's site across Spenard Road. The ADEC CS program requests that you have those three monitoring wells 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 the Jan 2008 scheduled 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 two 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 and it was requested to review decision to discontinue monitoring of groundwater by Holiday (Chevron will continue at three wells), and whether site could be considered a candidate for closure with ICs decision. |

Update or Other Action |
Several attempts were made to contact the owner of downgradient property located at 1805 McKinley Ave with a private drinking water well (as indicated online at the Muni website and a call to AWWU). These contacts did not eliminate the possibility of a private well remaining at that property. Several messages were left for the property owner with no response/reply. This info was passed on to the PM for Chevron 9014. |

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 conditional closure with ICs (CC-IC) letter dated 12/4/09 was not signed, ADEC has determined that this site should remain in active status. Therefore, a letter was sent on this date rescinding the decision letter dated 12/4/09. Two records with the same file number (2100.26.031) and different Hazard IDs are currently active for this site. |
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 (by Holiday or chevron), ADEC left a voicemail message for the owner of the home at 1805 McKinley Ave. As of today (3/24/10), I have not received a response, nor have past calls been answered. This individual phoned ADEC on 3/9/2010 inresponse to their receipt of a letter sent by ADEC. Since messages have not been returned in the past, ADEC will wait to be contacted, once again, by this individual. The residence directly east also has a private drinking water well, which was 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 shut off VEAIS for a rebound test. System was restarted after January 2010 release. Groundwater samples were also collected in January and May of the year from select wells nearest source and were nondetect. VEAIS data has shown a decrease in recovery since being restarted. Anticipate that all of this information will be reported in an upcoming report and the earlier CC with ICs decision will be revisited. |

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 prevent 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 pathway 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. |

Document, Report, or Work plan Review - other |
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 exceedances 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. |
Keather McLoone |
10/28/2011 |
Update or Other Action |
Email to Holiday and their consultant indicating that another round of groundwater sampling in the spring is appropriate for this site. Will review the data once available to determine if any additional investigation is needed at this site. |

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 supposed to have been decommissioned, but doing so would have affected the VES. Shannon & Wilson will address this issue by January 1, 2013. |
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). |
