Document, Report, or Work plan Review - other |
DEC approved the 2015 Remediation System Annual report. The report discusses the sub-slab depressurization and soil vapor extraction systems and annual evaluation of each at the systems at the GAVTC site. Due to the reduction of benzene emissions from 2005 through 2015 and the low benzene recovery rate during the system operation in 2014 and 2015, the report recommended that current sub-slab soil gas concentrations be evaluated to determine if ADEC vapor intrusion criteria are exceeded when the SSD/SVE systems are turned off.
The systems will be evaluated for replacement as part of the final site remedy under the performance based remediation contract, which is scheduled to be implemented in 2017. |

Document, Report, or Work plan Review - other |
DEC approved the Galena Aviation Vocational Technical Center (GAVTC) Subslab Soil Gas Sampling Memorandum. The memorandum described the results of three subslab soil gas sampling events at the Galena Aviation Vocational Technical Center (GAVTC) during the period of December 2015 to April 2016. The report recommended that the operation of the GAVTC SSD/SVE systems be discontinued based on the subslab soil gas sample results which indicate that concentrations are sufficiently low such that regulatory risk criteria will not be exceeded with the SSD/SVE systems turned off. DEC agreed with the recommendation. The system has been turned off but will remain in place for future use/evaluation during the remediation of the site ST005 plume. |

Update or Other Action |
The GAVTC subslab depressurization system was turned on concurrent with the startup and operation of the Horizontal sparging wells for the site ST005 remediation system. The GAVTC subslab depressurization system is mitigating potential vapor intrusion to the GAVTC building. |
