Document, Report, or Work plan Review - other |
Received sampling and analysis results Oct. 16, 2003. GRO and DRO concentrations in MW-1 were 2.24 and 2.85 mg/L, respectively. Benzene was 0.056 mg/L. Two wells installed between the Cornerstone Mall and the Fred Meyer store showed no evidence of contamination, indicating that fuel contamination on the Fred Meyer property did not arise from the Cornerstone Mall. A request for NFRAP was denied pending information regarding the disposition of stockpiled soil. Staff informed the property owner of the requirements for and steps necessary to achieve NFRAP status and explained that long term monitoring would be necessary. |
Sharon Richmond |
2/24/2004 |
Update or Other Action |
The report describing the September 2003 sampling requested a NFRAP. On Dec 19, 2003 Richmond responded, requesting information. A response was received January 9, 2004. Some of the information requested included documentation of the final disposition of 65 cy of contaminated soil removed offsite without DEC permission. The soil was reportedly stockpiled on another property owned by Mr. Dennis Wise, the previous property owner. DEC is preparing a letter stating the information regarding the final disposition of the soil is not sufficient for a NFRAP but would accept the previous long term monitoring plan so long as the time period for sampling would be changed to reflect the need for monitoring until groundwater had been determined clean in 3 consecutive samplings. |

Institutional Control Record Established |
The Notice of Environmental Contamination for Lots 205,206,208,209, and 211 was recorded at the State recorder's office. The notice declares that there is remaining soil and groundwater contamination that has not been completely delineated. This remaining contamination may be a risk if excavation were to occur, the land use changed from commercial to residential, or new buildings were constructed. Annual groundwater monitoring of MW-1 is required in the conditional closure and a vapor intrusion assessment. Vapors that may exist from the known subsurface contamination have not been investigated. |
Douglas Bauer |

Conditional Closure Approved |
Conditional Closure issued requiring a vapor intrusion assessment. |
Douglas Bauer |
11/19/2007 |
Update or Other Action |
Staff sent a letter to the building owner indicating vapor intrusion assessment needed to be completed in order to satisfy the terms of the conditional closure letter. The letter described the recommended methodology for the assessment and was copied to the consultant. |
Ann Farris |
12/17/2007 |
Update or Other Action |
Site visit conducted with the consultant and owner to determine technique and location for air sampling. The building has a crawl space. We spoke about 2 crawl space samples, 2 indoor air samples, and 1 outdoor air sample. The consultant indicated they would send me a current building layout and a figure with the details of the old gas station to confirm those samples and their locations would in fact be adequate. |
Ann Farris |
11/9/2008 |
Update or Other Action |
The vapor intrusion assessment for the current building on site has been completed. Crawl space, indoor air, and outdoor air samples were collected in February and June 2008. These assessments were completed to fulfill one requirement of the conditional closure that DEC issued for this site in a letter dated June 19, 2007.
The results of both the winter and summer assessments indicate that vapor intrusion is not occurring at the existing building on site. The crawl space, indoor air, and outdoor air concentrations were similar and below the action levels for commercial buildings. No vapor mitigation or remediation of soil or ground water is required to address this pathway at this time. Should land use change at the site or new buildings constructed, the remaining soil and groundwater contamination should be considered. |

"Annual Groundwater Sampling" report received from Travis/Peterson. MW-1 was sampled and analyzed for GRO, DRO, and BTEX on August 26, 2014. Results indicated a slight increase in total xylenes and detections at the method detection limit for remaining BTEX constituents except toluene, which was non-detect. Benzene concentrations are still above the ADEC groundwater cleanup levels in both the primary (0.0411 mg/L) and duplicate (0.0412 mg/L) samples. As DRO and GRO concentrations have remained below the most stringent ADEC cleanup levels since 2011, DEC will require MW-1 be sampled for BTEX only in future annual sampling events. DRO and GRO can be excluded from future sampling. |
Kristin Thompson |

"Annual Groundwater Sampling" report received from Travis/Peterson. MW-1 was sampled and analyzed for BTEX on August 22, 2017. Results demonstrate a decrease in concentration of benzene, total xylene, and toluene. Ethylbenzene was not detected in the project sample. The trip blank results were all non-detect for BTEX constituents. This is the second consecutive year that contaminant concentrations have been below the most stringent ADEC cleanup levels. If next year's sampling indicates contaminants remain below cleanup levels, ADEC will consider removing future groundwater monitoring requirements. |

Document, Report, or Work plan Review - other |
The September 14, 2020 groundwater monitoring report for this site was received and reviewed. One monitoring well (MW-01) was included in this event. Although only a BTEX analysis was required but a full VOCs panel was run inadvertently. Benzene concentrations continue to decrease and were not detected in the original sample and the duplicate sample concentration was well below the Table C cleanup levels. Out of the other VOCs the only detection was Trichlorofluoromethane and it was below the Table C cleanup levels. Monitoring will continue until all analytes are below cleanup levels for three consecutive years. This is the second consecutive sampling event that showed contaminants below Table C cleanup levels. The next sampling will be completed in the later summer of 2021. |

Long Term Monitoring Workplan or Report Review |
Groundwater monitoring of MW-1 was completed on September 1, 2021 for BTEX. All constituents were below cleanup levels. This is the third consecutive year that concentrations are below cleanup levels. The extent of the contaminant plume is known. Existing institutional controls
(asphalt encapsulation) appear to be working.
MW-1 will be sampled again in 2022, although three consecutive years of monitoring below
applicable DEC cleanup levels has occurred it is the owner’s preference to continue sampling at
the Cornerstone Mall MW-1 location.
