APC's activities finished. All but 60 drums of chemicals were disposed of by reuse or recycling. The remaining drums consist of petroleum and hazardous substances and need active management. Over 200 drums of wastes are stored in the northwest room of the main building. |

Reviewed office file. The following is a brief history of the site:
In 1992, Biotech Services, which was owned by Don Burke, requested approval to operate a remediation facility at the subject site after the facility had received contaminated material. The remediation process proposed uses a four stage process consisting of the following steps:
1. Preliminary preparation of the contaminated soil - temporary storing contaminated material on a storage pad and screening rocks and gravel from fines.
2. Treatment of rocks and gravel using dissolved air flotation system and biosurfactant
3. Treating water from dissolved air flotation with absorbent columns
4. Bioremediaton contaminated soil with bacterial derived biosurfactant.
Mr. Burke started remediating contaminated material in 1992. In 1993, the Department determined that all contaminated material proposed to be treated at Biotech Services required site specific plan approval. Soil that had been treated at Biotech Services from four different sites was analyzed and the levels of DRO reported to the Department did meet cleanup levels. This soil was stored outside without a liner. Biotech claims at this time that the elevated DRO is biogenic interference. In 1994, the Department notified Mr. Burke that significant facility features had not been completed by June 1, 1994, the Department would shut the operation down. The features included: monitor well installation and sampling, construction of a soil screening pad area, construction of a concrete soil storage pad and a lined post treatment soil storage area which would insure secondary contamination did not occur. The Department was also called to the facility since a fire involving one of the buildings on site was discovered. Upon arrival it was determined that an unknown type of material was burning at the end of the large Quonset hut structure known to store contaminated material. The fire is believed to be caused by vandalism and resulted in secondary soil contamination near the Quonset hut structure. Issues discovered during the site inspection include: sorbent pads from Indian Valley - DFSC fuel spill were placed on the ground without proper storage; frozen water and gasoline noted on the ground; waste oil drums stored at site and leaking. In August of 1994, the Department requested that responsible parties of contaminated material retrieve their contaminated materials for proper disposal.
In 1995, Mr. Burke was convicted of 4 counts including: not notifying department of an oil spill, unpermitted discharge of non-domestic waste water, maintaining unsafe public water system conditions, and a public water system proximity violation. Responsible parties initiated the collection of the their contaminated material and addressed secondary contamination issues.

Update or Other Action |
Discussed the status of the site with former ADEC personnel Mike Krieber and Bob Fultz. Both Mr. Fulz and Mr. Krieber worked for the Department's Wasilla office when the Biotech Services Facility was being dismantled and contaminated material was being cleanup up. Both Mr. Fultz and Mr. Krieber confirmed that all secondary contamination at the former Biotech Services Facility had been cleanup according to the Departments satisfaction. This site wil be listed as non qualifying. |

Site Reopened |
Staff reviewed Phase I and Phase 2 Environmental Site Assesments that were conducted by Terrasat, Inc. in 2007. DEC recieved these reports on June 2, 2012. The reports documented soil and potential groundwater contamination on the property. A test pit advanced north of the main building documented soil contamination. GRO, DRO, 1,1 Dichloroethylene, 1,1 Dichloroethane, benzene, carbon tetrachloride, and chlorobenzene were detected in soil samples at values that exceeded 18 AAC 75.341 Table B1 or B2 migration to groundwater cleanup levels. |

Document, Report, or Work plan Review - other |
Reviewed Site Characterization and Corrective Action Work Plan for the former Bio-Tech services site, 5577 East Fireweed Road. The objective of the proposed work is to evaluate the nature and extent of any contamination present at the property and to determine if groundwater has been impacted. Several Areas of Concern will be investigated including: surface stains, the area near former Test Pit 1 where hydrocarbon impacts were noted during previous investigations, the septic system lift station, former drum and container storage areas, and other areas expected to be identified during site characterization activities. Depending on its configuration, the septic system may need to be closed under the EPA UIC program. Test pits will be excavated in areas of concern, and if contaminated soil is identified, it will be excavated, stockpiled on site for treatment, and confirmation samples will be collected. Approximately 6 soil borings will be advanced to between 5 and 10 feet below ground surface and two soil samples collected from each borehole. Monitoring wells will be installed into each of the 6 boreholes and the wells will be purged, then sampled. A potable well without a pump is present at the site and will be purged and sampled. Surface stains will be excavated until visually removed and confirmation soil samples will be collected. Several containers of used oil and other liquids are reportedly present at the site. The contents of these containers will be characterized and the containers will be disposed of at an approved facility. Contaminated soil will be treated via thermal remediation at ASR, or potentially land farmed on site if appropriate. |

Meeting or Teleconference Held |
ADEC staff met with the site contractors to discuss site characterization and a path forward for site cleanup. Additional excavation will take place in areas where there are exceedances of petroleum and chlorinated solvents. |

Site Characterization Report Approved |
ADEC reviewed the Site Characterization and Corrective Actions Report for the Former Bio-Tech Services site. Approximatly 87 cubic yards of soil was excavated and taken to an approved offsite disposal facility. Another 120 cubic yards of PCE contaminated soil was landfarmed onsite. Groundwater monitoring wells were sampled and results showed groundwater was not impacted. Residual contamination in the soil above migration to groundwater cleanup levels is limited to DRO, PCE, and arsenic. Arsenic is considered consistent with background levels and the DRO and PCE are present below Inhalation/Ingestion and Direct Contact cleanup levels. ADEC sent a letter to responsible parties indicating that the requirements for site closure are that the groundwater monitoring wells and the landfarm must be decomissioned according to ADEC guidance. |

Final Cleanup Report Reviewed |
The Landspread Closure Soil Sampling Data report was received by ADEC. THe landfarm was sampled in November 2013 and showed concentrations of PCE ranging from 24.6 ug/kg to 60.2 ug/k, above the cleanup level of 24. A second sampling effort conducted in May 2014 showed PCE results ranging from 7.97 ug/kg to 25.3 ug/kg |

Cleanup Complete Determination Issued |
A cleanup complete determination was issued with the following ICs:
1. Any future change in land use may impact the exposure assumptions cited in this documnet. If land use and/or ownership changes, curent ICs may not be protective and ADEC may require additional remediation and/or ICs. Therefore any changes in land use or ownership must be reported to ADEC.
2. Future installation of groundwater, industrial or drinking water wells will require approval from ADEC.
3. Any proposal to transport soil or groundwater offsite requires ADEC approval in accordance with 18 AAC 75.325(i).
4. Movement or use of contaminated material in a manner that results in a violation of 18 AAC 70 water quality standards is prohibited. |
