MT 59044 -0909 May 28, 2010 JUN 2 2010 Ms. Rebecca Holmes Permitting and Compliance Division E C r !,. r , R E L Montana Department of Environmental Quality C I 1520 East 6 Avenue Helena, Montana 59620 -0901 Project No. 0110844 Subject: Response to Observed Oily Film on Ground Water at the City of Laurel Wastewater Treatment Plant Adjacent to the Laurel Refinery CHS Inc.; Laurel, Montana Refinery Dear Ms. Holmes: In response to your letter dated April 22, 2010, CHS, Inc (CHS) is providing a summary of actions performed and proposed path forward in regards to the oily film observed on the groundwater in two test pits that were excavated to support the water line installation for the City of Laurel, Montana Wastewater Treatment Plant (WWTP). Oily film was observed in two distinct locations (Site #1 and Site #2) by city contractors during the installation of an underground water line leading to the WWTP (Figure 1). The observations were reported to the Montana Department of Environmental Quality (MDEQ) by the City of Laurel on March 31, 2010. Site #1 is located on Laurel Refinery property, within the Southeast Interim Measures Area, and Site #2 is located on the WWTP property. The two areas are non- contiguous, and approximately 400 feet apart. A summary of observations, actions performed, and proposed path forward of each site are provided below. Site #1, Laurel Refinery Property Dark gray to black discoloration and staining of soil, and small quantities of black, light non- aqueous phase liquid (LNAPL) were observed at Site #1. Soil removed from the excavation was reused as backfill and placed above the static water level after completion of construction activities. Excess clean soil was stockpiled on Laurel Refinery property. Ground water removed from the excavation during construction de- watering was collected by vacuum truck and delivered to the refinery's waste water treatment plant. The observations at the Site #1 excavation are characteristic of the historical LNAPL smear zone previously identified at the refinery. The area in the vicinity of monitor well RT -39 (upgradient of Site #1) is known to have these LNAPL smear zone features and residual, highly weathered LNAPL. LNAPL and the associated dissolved -phase plume are currently being monitored as part of the CHS Southeast Interim Measures Area. Ground water monitoring is being conducted through the quarterly gauging and semi - annual sampling of monitor wells, including well RT -39. The area within the vicinity of Site #1 was also historically investigated as part of the Laurel Refinery's C\ Documents and Settings \RNissen \Local Settings \ Temporary Internet Files \OLK38 \15004HItr(MDEQ).doc May 28, 2010 Montana Department of Environmental Quality Page 2 RCRA Facility Investigation and reported to MDEQ. As Site #1 is located in the vicinity of previously investigated soil and ground water that may consist of residual LNAPL having degraded concentrations of light -end hydrocarbons, CHS proposes to continue with current interim corrective measures and to conduct further activities as proposed in the refinery's Corrective Measures Study. Site #2, WWTP Property Dark gray discoloration of soil, and small quantities of brown LNAPL were observed at Site #2. The LNAPL observed at Site #2 looked different than at Site #1 in respect to color (brown vs. black) and texture (globular vs. homogenous) suggesting these are different types of non - aqueous liquid. Soil removed from the excavation was reused as backfill and placed above the static water level after completion of construction activities. Ground water removed from the excavation during construction de- watering was managed as follows: • Initially removed by vacuum truck and delivered to the refinery's waste water treatment plant; • Second, pumping to two on -site frac tanks for temporary storage until vacuum trucks removed the water and delivered it to refinery's waste water treatment plant; and • Finally, pumping to the on -site frac tanks, then through activated carbon filter treatment prior to being sent to the Laurel WWTP (as approved by MDEQ). At the completion of construction activities, the frac tanks did not have LNAPL mixed with the silty residuum from the excavation. The silty residuum was removed from the frac tanks by vacuum truck and transported to the refinery's vacuum truck wash -out box. All material at the wash -out box is handled as hazardous waste. A ground water grab sample was collected by city of Laurel contractors from Site #2. Reported constituent concentrations (Laboratory Report attached) from the sample are significantly less than both the MDEQ spill response Risk Based Corrective Action (RBCA) and DEQ -7 water quality standards, suggesting ground water is not impacted by hydrocarbon - related constituents. In addition, ground water data from the on -going ground water monitoring program in the AOC -7 Interim Measures area (wells RT -35, RT -36, and RT -53, located upgradient of Site #2) demonstrates: 1) Constituents have not migrated onto the WWTP property from upgradient parcels of the Laurel Refinery; and 2) Reported constituent concentrations are less than DEQ -7 standards since 2002 and continue to decrease at the property boundary. Based on no exceedance of any water quality standards in the reported analytical data from the grab ground water sample, and on -going ground water monitoring at the Laurel Refinery property boundary continues to demonstrate the absence of of site migration, Site #2 does not warrant additional investigation. C: \Documents and Settings \ RNissen \ Local Settings \Temporary Internet Files \ OLK38 \ 15004Hltr(MDEQ).doc May 28, 2010 Montana Department of Environmental Quality Page 3 Proposed Path Forward In summary, CHS proposes no additional action at these two sites based on: • Risk -based investigation and interim corrective measures in the vicinity of Site #1 have demonstrated that human health and the environment are currently protected; • Reported analytical data from ground water at Site #2 indicates constituent concentrations are less that water quality standards; and • On -going ground water monitoring upgradient of Site #2 has demonstrated that potential migration of hazardous constituents is being effectively controlled within the Laurel Refinery property.
