Problems/Comments

Previous heating oil system consisted of an AST at the adjacent Kathy Estates Trailer Court and an associated 1 inch steel piping buried at a depth of 16 to 18 inches below ground surface which distributed heating oil to the trailers at the L and L Trailer Court. The heating oil line entered the property at the northeast corner. This system was abandoned in place in 1975 when natural gas was piped into the trailer park. Access roads on the property historically were oiled on an annual basis. A break in the heating oil line occurred at an unknown date that spilled an estimated 2 gallons of fuel. Surface staining was observed on site where a grader is parked and areas where engine parts and oil are stored. NFRAP in place until the GW and soil at the GW interface can be demonstrated to be below soil and GW cleanup levels for DRO. Groundwater is approximately 6 feet below ground surface. Anchorage Water and Wastewater Utility does not service this property with drinking water. Drinking water is obtained from a well on the property. Based on the MOA Property Appraisal web site the subject property was sold by Holy Rosary Academy to Charles F. McAlpine. The date of the deed change was 5/11/06.

6/25/2002	Site Characterization Report Approved	The department received a copy of the Shannon & Wilson, Inc. report "Phase I and Limited Phase II Einvironmental Assessment, Lot 1, Block C, Spenard Acres Subdivision, Anchorage, Alaska" dated June 2002 documenting groundwater contamination of 1.53 mgL DRO and soil contamination of 1020 mg/kg DRO. Report recommended further characterization. The department also received a copy of the trailer court drinking water well sampling results from Northern Testing Labs dated 6/20/02 that were collected by Mr. Cain and sumbitted to the lab on 6/5/02. The results look fine.	Elizabeth Stergiou
7/17/2002	Site Added to Database	Actual spill date unknown. Date first samples were collected was used.	Elizabeth Stergiou
8/22/2002	Update or Other Action	Reviewed the August 13, 2002 work plan entitled "Phase II Environmental Site Assessment Work Plan, L & L Mobile Home Park, Anchorage, Alaska" prepared by Shannon & Wilson, Inc. for Mr. Lester Cain, received by the department 8/15/02. The objective of the subject work plan is to excavate the diesel impacted soil in the northeast section of the property contamination, the installation of three monitoring wells near the location of previous borings. ADEC did not approve the work plan and requested the following: An updated diagram that includes the proposed location of the contaminated soil stockpile, a description of the proposed screening depth and slot size for the three monitoring wells, and characterization of the contamination found at boring B1 contamination above cleanup levels, and a quarterly drinking water monitoring plan for the drinking water well located on the property.	Elizabeth Stergiou
9/23/2002	Site Characterization Workplan Approved	The September 17, 2002 Shannon & Wilson, Inc. "Revised Phase II Environmental Site Assessment Work Plan", received by the department 9/19/02 is approved. The Department offers the following comments and recommendations: physically measuring the distance from the proposed stockpile location to Fish Creek to ensure compliance with 18 AAC 75.370(a)(2)(A). If the proposed stockpile location is not more than 100 feet from Fish Creek, then an alternative stockpile location will need to be submitted to the Department for approval. It is recommended the pipeline near the location of boring B1 be assessed as a potential source for the contamination at boring B1.	Elizabeth Stergiou
9/25/2002	Site Characterization Workplan Approved	Approved the Shannon & Wilson, Inc. "Addendum to the Revised Phase II Environmental Site Assessment Work Plan, L & L Mobile Home Park" dated September 24, 2002.

"Phase II Environmental Site Assessment and Cleanup" report dated December 2002, received by the department 12/12/02, documenting the installation and sampling of three monitoring wells, excavation and sampling of three test pits, and excavation and sampling of one source area. The Department requests further site characterization of the soil around MW1 and test pit 2 where diesel range organics results were 940 mg/kg and 373 mg/kg respectively. It is recommended groundwater monitoring continue on a quarterly basis for at least one more quarter.	Elizabeth Stergiou
3/18/2003	Site Characterization Workplan Approved	Staff reviewed the Shannon & Wilson, Inc. "Site Characterization and Groundwater Monitoring" report dated 3/10/03, received by the department 3/13/03. The plan proposes drilling and sampling of four borings near contamination found in the area of MW1 and test pit 2, and collection and analysis of groundwater samples from the three onsite monitoring wells. The plan is approved with the following comments. 1. The proposed boring located in the road, and the more south of the two borings in the road, could be moved to the area just north of the trailer that is just north of MW1 and test pit 2, and north of MW1. 2. The number and location of the proposed borings may, or may not, be adequate to determine the horizontal or vertical extent of contamination. Further sampling may be necessary. 3. The final report should include a table of the field screening results and locations in addition to the analytical sample information. 4. The Department requests that the soil stored from 2002 be disposed as soon as possible or transferred to a longer term storage cell.	Elizabeth Stergiou

Received an email from a contractor that has been charged with decommissioning the monitoring well this spring. The internal reminder system has been set to check back in mid-summer if we have not received verification yet.

Update or Other Action

EPA Targeted Brownfields Assessment team submitted a memorandum on L & L Mobile Home Court dated April 1, 2019 to ADEC. The site was originally slated to receive assessment from EPA's Targeted Brownfields Assessment program in the summer 2019. However, due to obstructions present that would prevent the EPA from sampling the fuel distributions lines, the EPA is postponing any field work for a date after the site has been more fully cleared. The memorandum includes a site summary, geophysical survey results, and recommendations for further sampling.
