Update or Other Action |
A review of the file indicates that on Sept. 5, 1997, PERP received a complaint regarding a UST excavation on Madcap Road with free fuel in the bottom of the excavation. PERP staff responded to the complaint and observed free product in the bottom of the excavation, and also in the sump of an adjacent underground boiler room. The heating oil tank was still on-site. Pictures in the PERP file show multiple holes in the tank. PERP staff oversaw removal of over 1600 gallons of product from the excavation, sump, and a recovery well. A Notice of Violation was issued on September 18, 1997.
Sent PRP letter to the RP and current land owner.

Meeting or Teleconference Held |
Met with the current property owner who indicates he is willing to conduct a release investigation. Explained the site cleanup process, conditional closures, and institutional controls, but forgot to discuss deed notices. Though it is early in the process, this topic should be discussed in future meetings. |

David Watts called to update his search on nearby wells (couldn't find any); inform DEC of his installation of 4" firebreak between boiler room & building, and 4" drainage pipe in gravel bed at base of building between building and fuel tank, and plans to pursue installation of a sub-slab ventilation system. Will update DEC later this summer. |

| 9/16/2014 |
Update or Other Action |
Suggested site work letter sent out. Recommended work included: installing an active vapor mitigation system beneath the building slab and exhausted out of the building, seal boiler room and basement walls and floor to prevent vapor intrusion from entering the building, extend the ventiation pipe from the boiler room away from building and human receptors, and cap the existing groundwater well. If these measures have been completed, the ADEC could begin the closure process. |

Update or Other Action |
The DEC received a call from David Watts indicating that he will be installing the vapor extraction system over the next few weeks and will be notifying the department when the installation is completed. |

Site Characterization Workplan Approved |
DEC staff reviewed and approved of the workplan to: advance four soil borings and collect 8 soil samples for DRO, VOCs and PAH analysis, advance four vapor probes in two clusters of two to collect soil gas VOCs at two levels, and to collect indoor air samples at four locations in the house and one outdoor location. |

Document, Report, or Work plan Review - other |
Draft Report received for Indoor Air and Soil Gas Sampling. All four indoor air results from three of the four apartments of the April 2021 sampling event were less than one-tenth of the target levels. Toluene, xylene, ethylbenzene and 1,2,4-trimethylbenzene were detected in some or all of the samples.
No contaminants were observed in the two shallow soil gas wells, with the exception of 1,3,5-trimethybenzene which does not have a target level and was not observed in indoor air. The presence of ice in one deep soil gas well prevented sample collection. However well SG-02 had exceedances of 1,2,4-trimethylbenzene (1200 µg/m3), benzene(58µg/m3), ethyl benzene(1100µg/m3), naphthalene(28µg/m3), and total xylenes(3600µg/m3). This well is closest to the source area of contamination. |

Site Characterization Report Approved |
The second soil gas and indoor air sampling event was completed in April 2021. VOC exceeded residential soil gas target levels at the deeper soil gas point on the east side of the house nearest the source. The sample collected three feet higher resulted in no exceedances. Indoor air sampling detections were all less than one-tenth of the associated target level. |

Site Visit |
DEC staff visited the site to observe the removal of four soil vapor extraction points and restoration of the locations to previous conditions. Staff also met with the RP to discuss current conditions at the site. |

Site Characterization Workplan Approved |
Work Plan Addendum for Soil Borings and Soil Sampling received on 8/1 has been reviewed and is approved. This plan includes drilling 3 borings near the northeast corner of the release area to complete delineation of heating oil contamination in this area. Work is planned for the week of August 8th. |

Site Characterization Report Approved |
Site characterization report for soil sampling has been received and approved. Three borings were advanced on the east side of the impacted area to determine if contamination extended into the Madcap right of way and to complete delineation of contamination. Diesel range organics was detected in samples collected from 12 to 13 feet below ground surface at each of the locations, however, all concentrations were below DECs most stringent soil cleanup levels. |
