Army (Beth Rodigari) Directorate of Engineering and Houseing reported release to Ron Klein who filled out an Oil spill report form. 5,000 gallon tank for used oil. Excavated around tank found oil contaminated soil. Extent not delineated, tank was empty, no analysis done yet. Age: 10-15 years old. Depth to groundwater 136 feet. Information needed: need to know depth to first water bearing zone. Soils information, extent and level of contamination, need sampling. Barrel and send south if contamianted with halogenated organics. Will research and get back to ADEC. |

Memo from Ron Godden Southcentral District Office Underground Storage Tanks to Ron Klein Anchorage Western District Office. Cathy Benedikisson, FRN Eng Eng, called today concerning the
spill at the subject location. She was very concerned about a major delay relating to the contractor not being able to work in the vicinity of the pit where the tank had been removed. She states they had removed all contaminated soil in the pit as per use of the olfactory sensor and a Hnu meter. She desired permission to backfill with clean fill. She wanted your ok but
you were not available.
Since we have allowed this in the past, I told her that she could bapkfill if she would get a sample of the undisturbed soil at the bottom of the pit. This sample should be analyzed for total oil & grease and total Petroleum Hydrocarbons. Based upon the results of the analysis, the risk exists to have to do more remediation.
However, if the visual contamination had been removed, the Hnu could not detect vapors, etc, the likelihood of intensive remediation was small. The ground water is also at about 180 feet in the area. She should provide the results of the sample for review and perhaps a risk assessment would be required based upon that review. She stated that all the contaminated soil had been removed and placed on a concrete pad pending the results of the sampling. The residual in the UST had also been sampled. All the samples results will be provided when available. I didn't see any problem with this so gave her permission to backfill with clean fill. If you have a problem with this, please let me know. |

A.G. letter (Breck Tostevin) to Tamela J. Tobia, OS Judge Advocate for the Army. Letter states that a separate petroleum site compliance agreement should be separate from the CERCLA federal facility agreement. The petroleum site restoration agreement would function as a "two-party agreement" under the FFA. It would track the basic provisions of the UST Agreement but be tailored to the State's contaminated site regulations and would interface with the FFA. All petroleum sites addressed under the Two Party agreement would be reviewed in the final operable unit of the FFA and actions taken would be memorialized in a Record of Decision (ROD) under the FFA. |

Staff reviewed and commented on the April 1994 Draft UST Release Investigation, Building 45726 USTs 62 and 63. Fort Richardson, Alaska
The Alaska Department of Environmental Conservation-Defense Facilities Oversight group (ADEC) has received, on May 6, 1994, a copy of the above referenced report for building 45726. Below are our comments regarding the document.
2.2 Geology and Hydrogeology page 5
The text states there is one well located within one-quarter mile of the site (AP-2976). There was no reference in the report to exactly where the well is located in relation to the site. Please include information on AP-2976 in one of the figures such as the Post Map.
5 Remedial Alternatives page 20
ADEC concurs that the level D cleanup criteria was not exceeded at this site and will consider the site closed out. However, closing out of this site does not limit nor preclude ADEC from requesting future remediation or site investigation at a later date. If new information indicates that there is previously undiscovered contamination or exposures that may cause risk to human health or the environment, then future investigation and/or remedial actions may be required by ADEC. |

Staff reviewed and commented on the Site Assessment report reviews for UST work at Fort Richardson.
The Alaska Department of Environmental Conservation-Defense Facilities Oversight group (ADEC)
has received various documents concerning UST removals at Fort Richardson by Oil Spill
Consultants. Any closures approved by ADEC which were based on the reports' information will be
contingent on additional data gathered by Oil Spill Consultants. The following buildings are listed as having additional site screening samples taken to confirm the presence or absence of contamination that exceeds the soil matrix scoring for each site: 980, 812, 750E,750W, 45726, 784, 778, 55295. |

Staff reviewed and commented on the Site Assessment Report for Building 45726 Fort Richardson, AK
The Alaska Department of Environmental Conservation-Defense Facilities Oversight group (ADEC) has received, on July 25, 1994, a copy of the above referenced report. Below are our comments regarding the site assessment of UST 117.
5.3 Conclusion and Recommendations page 13
The text states the site is recommended for closure. Pending site screening results obtained from Oil Spill Consultants' work at this site, ADEC concurs with the recommendation. The site closure will be considered final contingent on the additional sampling that will confirm the presence or absence of soil contamination above level "C" criteria. |

Results From Additional UST Soil PID Screening! An~lyses
The Department of Environmental Conservation, Defense Facilities Oversight group, (ADEC) has received a fax of the document listed above on August 19, 1994. The analytical results for bldgs. 750E, 750W, 778, 784, 812, 980, 45726, and 55295 show levels well below the most stringent cleanup criteria. ADEC considers the UST sites closed out.
However, closing out these sites does not limit nor preclude ADEC from requesting future
remediation or site investigation at a later date. If new information indicates that there is
previously undiscovered contamination or exposures that causes an increased risk to human
health or the environment, then future investigation and/or remedial actions will be required. |

Site Characterization Report Approved |
Bldg. 45-726, the 23rd Engineer Motor Pool, is located off of Otter Lake Road. Underground storage tanks (UST) 62 and 63 were removed in 1990. A formal site assessment was not conducted during the removal causing the site to be incorporated into the November 1993 Fort Richardson-State of Alaska Department of Environmental Conservation UST Compliance Agreement. A release investigation was conducted at the site in May 1994. Samples were found to be below laboratory reporting limits. |

Site Closure Approved |
Based on the data presented in the document, it appears that the site does not exceed the most stringent matrix level "A" criteria. DEC will grant a no further remedial action designation for this site. If in the future, additional contamination is discovered at this site, further investigation and/or remedial actions may be requested of the Army by DEC. DEC reserves its rights, under 18 AAC 75, 18 AAC 78 and AS 46.03 to require the Army to conduct additional assessment and/or corrective actions in the future if information indicates the site conditions pose a risk to public health or the environment. |

Update or Other Action |
Letter from Army to ADEC. On January 13, 1995, you met with Mr. Samuel P. Swearingen, and Major Kevin Gardener of the Environmental Compliance Branch. At this time you requested an explanation for the lack of spill protection on a number of underground storage tanks(UST) located at Fort Richardson. Below you will find a listing of those regulated tanks that were in question and an explanation of how the spill control requirement is met:
Tank#62A & 63A- These are used oil USTs with an ILS-350 interstitial monitor/overfill alarm system. The tank's spill control system consists of a catchement basin/floor drain system attached to an oil water separator. The tank is filled through manually pouring oil into either one of the floor drains or into a oil sink. The system is non-pressurized, and gravity fed. |
