It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.
Problems/Comments
Tetrachloroethene (PCE), trichloroethene (TCE), and dichloroethylene (DCE) contamination from a former dry cleaner. The site is part of a larger area-wide effort to track the groundwater contamination from multiple sources. This property is also tracked as an individual site because it was a former dry cleaners and a source of soil and groundwater contamination is believed to be located at the Southeast corner of the building. This source is causing vapor intrusion concerns for the building. The building is located on Gaffney Road and is currently occupied by Forget Me Not Books, Sunshine Alterations, Stone Soup and Coin King Laundromat. The investigation to date indicates that the plume likely comingles with the Gaffney West plume. Neither plume extends to the city drinking water wells, which are approximately 1/2-mile downgradient of the site. See also related site Gaffney Road Area-Wide (Hazard ID 2919) and Gaffney West/ Royal Masters Launderette (Hazard ID 4503).
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 10/26/2010 | Site Added to Database | A new site has been added to the database | Mitzi Read |
| 1/3/2011 | Exposure Tracking Model Ranking | Initial ranking with ETM completed for source area id: 79000 name: Coin King | Tamara Cardona-Marek |
| 2/18/2011 | Site Characterization Workplan Approved | DEC received the Oasis Solvent Plume Characterization and Long Term Monitoring Plan for Gaffney east. Plume characterization includes groundwater plume delineation to the north of Carr's Foodland building and vapor intrusion assessment inside the building. | Tamara Cardona-Marek |
| 9/28/2011 | Site Visit | DEC conducted a site visit during the vapor intrusion assessments for 2011 at the Sunshine Alterations, Forget Me Not Books and Stone Soup buildings. An additional indoor air sample will be collected in the apartment section of the Sunshine Alterations building. | Tamara Cardona-Marek |
| 7/25/2013 | Site Visit | DEC met with EPA and conducted a site visit as part of an EPA Preliminary Assessment. | Tamara Cardona-Marek |
| 9/19/2013 | Document, Report, or Work plan Review - other | DEC reviewed a work plan for additional site characterization downgradient of the Coin King property (to occur simultaneously with EPA's preliminary assessment of the Coin King property). | Tamara Cardona-Marek |
| 3/18/2014 | CERCLA SI | A Draft copy of the EPA Site Inspection was received. Former project manager Tamara Cardona provided clarifying comments. A Final copy of the report was received in June. The report identified a soil source near the Current Coin King property. Concentrations were higher than those identified adjacent to the Coin King property boundary. The report documents a former PCE drum storage area on the south side of the Coin King building as a potential source of the release and speculates that additional solvents may have been released at the self serve car wash on the east end of the property. Groundwater PCE concentrations were detected at greater than 100 times the Table C cleanup level under the four-plex, with a detectable solvent plume extending north to 10th avenue. The soil source area extends from the back of the building out under the pavement on Airport way. | Kim DeRuyter |
| 5/7/2014 | Potentially Responsible Party/State Interest Letter | In response to the EPA Site Inspection results, staff sent a letter to the owner of the property informing them of their liability for the release of PCE and TCE on the property and requesting additional assessment. | Tamara Cardona-Marek |
| 7/23/2014 | Document, Report, or Work plan Review - other | DEC staff and legal advisors met with the owner/operator, legal and environmental advisors of the Coin King Laundromat property and followed up the meeting with a written request for an evaluation of remedial alternatives and a title search and insurance history for the property. | Tamara Cardona-Marek |
| 11/14/2014 | Update or Other Action | DEC received an evaluation of remedial alternatives letter report prepared by the property owners environmental representative. The cover letter asserts that Coin King Inc. is not liable for the contamination. Little information is provided on how cost estimates were derived and no property ownership or insurance history was included. The report dismisses active remedial alternatives as cost prohibitive, and suggests that monitored natural attenuation MNA is the preferred alternative. The report proposes that the state continue conducting Long term monitoring. | Kim DeRuyter |
| 11/14/2014 | Update or Other Action | DEC conducted additional limited site characterization and groundwater monitoring which confirmed and further delineated the soil source area and groundwater plume previously detected by EPA. This work is documented in the Ahtna Engineering State Fiscal Year 2014 Gaffney East Report. Monitored natural attenuation parameters indicate that PCE is degrading to TCE and DCE. Vinyl chloride has not been detected at the site. | Kim DeRuyter |
| 2/20/2015 | Site Visit | Staff conducted a site visit with our support contractor to meet the business owners and become familiar with the site. | Kim DeRuyter |
| 7/9/2019 | Document, Report, or Work plan Review - other | Received Alternatives Analysis report authored by NORTECH on behalf of ADOT (road improvement project) | Jim Fish |
| 2/5/2021 | Document, Report, or Work plan Review - other | Received 2020 contractor report for Gaffney West SSd/SVE system maintenance & operations, and Gaffney East/West groundwater sampling | Jim Fish |
| 10/17/2022 | Update or Other Action | Approved a work plan from ADOT&PF for 33 soil borings in ROW associated with Cushman St and Airport Way and a future road improvement project. Samples for VOCs will be collected at 3-foot and 10-foot depth intervals will fill data gaps and inform development of a Quality Assurance Project Plan (QAPP) for the Airport Way/Cushman Street Intersection Reconstruction Project, administered by the Alaska Department of Transportation (ADOT), and anticipated to begin during 2023. because of the likelihood of encountering contamination categorized as F-listed waste from former dry cleaners (under the Resource Conservation and Recovery Act or RCRA), excess soils from borings will be containerized and stored in a satellite accumulation area. A RCRA Hazardous Waste Generator status and site I.D. number from the U. S. Environmental Protection Agency (USEPA), and analytical results from soils, will be used to determine proper waste disposal under RCRA. | Jim Fish |
