Document, Report, or Work plan Review - other |
Staff received a work plan from PERP to investigate a release of approximately 1400 gallons of ultra--low-sulfor diesel near the "FSSI" building. An estimated 500 gallons overflowed from the secondary containment. Excavation occurred to the extent practicable, but it was in a tight spot near the building and piping infrastructure. 14 soil samples will be collected at the limits of excavation and analyzed for GRO, DRO, BTEX and PAHs. Three monitoring wells will be installed downgradient and sampled for the same contaminants. Flint Hills North Pole Refinery is immediately downgradient of the Petrostar facility. |

Site Characterization Report Approved |
DEC reviewed the gasoline release cleanup report for spill #10309933601. The amount released was much larger than originally believed, and consisted of as much as 230 gallons of gasoline. GRO, DRO, and benzene contamination remain on the eastern portion of the excavated area at a depth of about 5 feet. Shannon and Wilson recommend a groundwater investigation due to the shallow aquifer at this site. Stockpiled soil will be landfarmed in a lined, fertilized biocell. |

Meeting or Teleconference Held |
DEC met with Petro Star to discuss several sites. Shannon & Wilson is continuing work at the refinery for both the Ultra-low Sulfur Diesel (ULSD) spill and the gasoline spill. Recent work indicated no current downgradient impacts to groundwater at the ULSD spill. Shannon & Wilson is proposing long-term monitoring at this source area. Groundwater investigation is planned for the gasoline spill and Shannon & Wilson is awaiting DEC's approval of a workplan to install temporary well points downgradient of the spill. |

Document, Report, or Work plan Review - other |
DEC reviewed the ULSD Release, Additional Soil and Groundwater Characterization report for the Petro Star refinery. The investigation found no additional impacts to soil above cleanup levels in four borings north and northwest of the release and existing monitoring wells. Groundwater samples from MW-10-02 contained DRO in excess of cleanup levels, and MW-10-01 was not sampled because of the presence of free product (LNAPL). Downgradient groundwater samples from MW-10-03 and temporary well points did not contain contaminants in excess of cleanup levels. Shannon and Wilson recommends that LNAPL be monitored and removed when practicable, and that groundwater concentrations be monitored annually for at least three years to evaluate trends. |

Document, Report, or Work plan Review - other |
DEC reviewed the Monitoring Well Installation and Sampling Report for the 2010 gasoline release. Benzene and toluene were detected in some groundwater samples but at concentrations below cleanup levels. Remaining soil contamination is limited in extent to a small area. Shannon and Wilson recommends additional groundwater sampling in spring of 2016 followed by an evaluation of closure for this source area. |
