We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.
Problems/Comments
Elevated levels BTEX, DRO, and metals contamination detected in lab analysis of sludge sample from seepage pit servicing the maintenance shop floor drain. Extent of soil contamination around the seepage pit is not known. Groundwater monitoring well was placed near the seepage pit in the direction of and 75 feet from the Big Lake Shoreline. Well sampling analytical results showed detectable contaminants similar to the seepage pit analytes but at concentrations below applicable cleanup levels. Phase I Site Assessment by GE2T in 10/1999. SA and Release Investigation 12/2000 by GE2T. Local population is residential, 85% served by private drinking water wells and septic systems.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 3/20/2001 | Update or Other Action | CSRP provides comments to the owner of Burkeshore Marina in response to his consultant Gilfilian Engineering's 12/29/00 dated report "Floor Drain Site Assessment and Release Investigation." CSRP requested that further characterization be performed at the site. The characterization report showed metals and petroleum in soil and groundwater. | Jim Frechione |
| 4/17/2001 | Cleanup Plan Approved | CSRP conditionally approved of the owner's 4/16/01 work plan to excavate and remove the leach tank at the site provided that a sampling plan be submitted to ADEC and information be provided how the hazardous materials will be removed from the site. | Jim Frechione |
| 4/18/2001 | Update or Other Action | On 4/18/01, information was provided to ADEC that showed that Energy Recovery Services would transport and dispose of the hazardous waste soil/sludge/water that would be removed from the tank at the site. | Jim Frechione |
| 4/20/2001 | Site Added to Database | Metals, BTEX and DRO present in sludge above applicable cleanup levels. | Bruce Wanstall |
| 4/20/2001 | Site Ranked Using the AHRM | Preliminary Ranking. Groundwater contamination scored as unknown pending further review by staff. | Bruce Wanstall |
| 4/24/2001 | Update or Other Action | On 4/24/01, CSRP provided comments to Gilfilian's 4/23/01 work plan to further characterize the site. CSRP also informed the owner that he should contact Fish and Game because Big Lake is classified as an anadromous fish lake and the contamination is close to the lake, and contact Jonathan Williams of EPA UIC program because the septic system appeared to be a UIC. | Rich Sundet |
| 5/15/2001 | Site Characterization Workplan Approved | On 5/15/01, CSRP approved of Gilfilian's 4/25/01 work plan to further characterize the site. Per Darci Bowers of Gilfilian, work was scheduled to begin on 5/16/01. | Rich Sundet |
| 5/15/2001 | Update or Other Action | On 5/15/01, EPA issued a letter to Gilfilian informing them that the Burkeshore Marina was a UIC Class IV well and the system is regulated under EPA regulations, and a closure report needed to be submitted to EPA as well as to DEC. | Rich Sundet |
| 9/26/2001 | Site Closure Approved | In a letter dated 9/26/01, CSRP approved closure of the site. The closure was based upon information provided in Gilfilian's report "Floor Drain Seepage Pit Corrective Action" dated August 14, 2001 that was received by CSRP on 8/21/2001. The report summarized findings from work that was performed in May 2001 in accordance to the work plan approved by CSRP on 5/15/01. The report noted that: -Wastewater and sludge from the seepage pit was removed, analyzed, and manifested off site as hazardous waste that exhibited the toxicity characteristic for cadmium (D006) and lead (D008). In addition to sludge exhibiting the hazardous waste characteristic of toxicity for cadmium and lead, sludge analysis showed high concentrations of petroleum hydrocarbons (e.g., diesel range organics (DRO) up to 42,200 mg/kg and residual range organics (RRO) up to 71,000 mg/kg, volatile organic compounds (e.g., benzene up to 0.226 mg/kg), and other metals (e.g., arsenic up to 29.0 mg/kg); -The concrete seepage pit was removed, cleaned and recycled; - Soil was excavated around the seepage pit, stockpiled, and analyzed. The stockpile was treated with lime and the mixture was landspread on-site; - Soil that was tested by field screening and deemed “clean” was used to backfill the area of the removed seepage pit; - Confirmation sampling was performed of the soils that remained in the pit after excavation; and; - The monitoring well located about 18 feet downgradient of the seepage pit was sampled. The letter also noted that in discussion with Mr. Robert Gilfilian of GE2T on September 24, 2001, it was noted that the septic tank had been routinely pumped out and the contents transported to Anchorage where they were discharged into the Anchorage Wastewater Utilities treatment facility. The letter noted that based on the information to date, the department concludes that soil impacted by the contamination was mostly below 18 AAC 75 Method 2 cleanup levels. Several soil samples of arsenic and chromium (total) were slightly over Method 2 cleanup levels for their migration to groundwater pathway, but the levels were within USGS published concentrations listed for regional background arsenic and chromium (total) concentrations in the Big Lake area. The department recognizes that the metals concentrations are within an acceptable range of background concentrations and/or a range close to the established cleanup level to not require further cleanup action. Groundwater monitoring showed that during two sampling events, no contaminants were detected above Table C cleanup levels and there is no evidence that the contamination has migrated to Big Lake. Based upon the information presented above, the department has determined that the cleanup actions have removed hazardous substances so there is no longer a risk to human health or the environment. Therefore, no further action is required at this site and it will be closed as a contaminated site. However, if future information is shown that contamination exists above cleanup levels or that contamination is migrating towards Big Lake, the department may require further action, including further assessment, monitoring, and/or cleanup. The letter noted that this decision does not preclude any action that the Environmental Protection Agency (EPA) may request of you. The department has been coordinating its review with Mr. Jonathan Williams of EPA’s Groundwater Protection Unit in Region X because the seepage pit is an injection well that is regulated by both EPA and the department. Mr. William’s office will soon be contacting you as well regarding the subject closure report. While the Contaminated Sites Program (CSRP) of the department is “closing” the aspect of the petroleum and metal contamination due to the seepage pit, CSRP requested that the RP contact Mr. Mike Skibo in DEC's Drinking Water/Wastewater Program to determine whether his program will require further actions to address any pathogenic problem associated with the spreading of the sewage sludge on-site, e.g., providing further lime treatment, and whether he will require further details on the work associated with the facilities wastewater disposal system. | Rich Sundet |
| 9/28/2001 | Update or Other Action | In a letter dated 9/28/01, EPA's Groundwater Protection Unit closed the Class IV injection well at the facility based upon Gilfilian's 8/14/01 dated corrective action report. On 5/15/01, EPA had approved of the Gilfilian work plan to perform the corrective action work. | Rich Sundet |
| 12/21/2001 | Update or Other Action | In a letter dated 12/21/01, DOL provided to ADEC a copy of a check for $919.96 from D&E Properties dated 12/15/01 to the State for cost recovery in the Burkeshore Marina spill. | Rich Sundet |
| 5/6/2004 | Site Number Identifier Changed | Change Region from 21 to 22. | Former Staff |
