Problems/Comments

The 'Trespass Shooting Range' was started in trespass in the early 1990s. It is located on a Section Line easement north of the Delta Junction Airport and between the Richardson Highway and Delta River. A letter was sent to the City regarding its trespass status in the mid-90s and the site had signage posted banning shooting and a large earthen berm was placed to reduce access along the river, a location used to dump items. This reportedly limited shooting for about 2-years, after which the public began to re-use the site since the berm acted as a natural barrier. The berm contains lead and brass from small munitions, and the ground is littered with shell casings. Various targets have been utilized and appear at various times and in various sizes. The aforementioned Section Line is between a piece of State-owned property and a large parcel the City is receiving via its Municipal Entitlement, and is a part of both properties. The State Division of Forestry was interested in upgrading the legal easement (as is on most Section Lines on State-owned lands) to access the timber across the Delta River, and the easement is generally needed for recreationists to access the Delta River. Meanwhile, the continuing use of the trespass range endangers the public that utilize the river and adjoining lands, as well as being a danger to air traffic utilizing the Delta Junction Airport. A Land Use Permit (LUP - LAS 26917) has been issued to the City for cleanup of the site; however, it is jointly recognized that the sampling for and disposal of lead from this trespass site is a potential liability and additional expense that neither entity is budgeted for. Preliminary data from a 2017 sampling event identified elevated lead levels >10,000 mg/kg, with results exceeding TCLP haz-waste characterization concentrations of 5 mg/L. Former file number: 120.57.002.

4/9/2009 Site Added to Database A new site has been added to the database. Mitzi Read
4/16/2009 Exposure Tracking Model Ranking Initial ranking with ETM completed for source area id: 78753 name: Delta Junction Trespass Shooting Range Deborah Williams
8/3/2009 Brownfields Award Notice to proceed was awarded to SLR through SPAR term contract. Project managed under Reuse and Redevelopment Program. FY 2010 State of Alaska Capital Improvement Project funds $41,545 awarded to DNR for a site characterization at Delta Junction Shooting Range. NTP# 18902814104. Current status: No characterization completed, work plan developed. Project complete. Deborah Williams
8/10/2009 Meeting or Teleconference Held DEC held a stakeholder meeting for the ADNR Delta Junction Shooting Range site. The participants for the meeting included representatives from DNR (landowner), DEC and SLR (consultant for the project). The purpose of the meeting was to discuss the objective for the work planned at the site (Assessment) and to give the consultant an opportunity to ask any questions pertaining to the field work. Deborah Williams
12/6/2011 Update or Other Action Assessment work was cancelled May 2010 because estimated cost of conducting source reduction, an objective of the assessment, was unlikley to be cost effective. It was determined that removing all lead-contaminated shooting range berm was more effective, and therefore no further assessment was required. Removal of berms estimated at several hundred thousand dollars. No funding available for cleanup at this time. Melinda Brunner
4/1/2016 Update or Other Action The City of Delta Junction is revisiting the potential to seek a Targeted Brownfield Assessment to help evaluate the risk of exposure associated with the development plans for a River Walk Park and Strip, that will intersect the shooting range and other trespass dump areas. A meeting was held between DEC and the City of Delta Junction to discuss a path forward to applying for this funding. John Carnahan
4/19/2016 Update or Other Action On behalf of City of Delta Junction, DEC submits TBA request to EPA. Requested an evaluation of risks posed by a trespass shooting range along with historical dumping practices, located in part on State property, and property that is part of a municipal entitlement to the City. Development proposals such as this can be difficult to move forward without a clear understanding of the environmental factors that can impede development opportunities. John Carnahan
6/2/2016 Update or Other Action Revised TBA submittal to EPA that corrected the land status in question. John Carnahan
6/22/2016 Brownfields Award EPA provided approval of the project for a Targeted Brownfield Assessment. $89,472 provided for TBA services. John Carnahan
12/6/2016 Document, Report, or Work plan Review - other Provide comments to EPA on proposed work plan. John Carnahan
6/21/2017 Update or Other Action EPA modifies work plan to eliminate drilling. John Carnahan
12/15/2017 Update or Other Action Received preliminary data confirming the presence of lead above DEC cleanup levels in proximity to the bermed area of the shooting range. Changed site to 'Active' status. Meeting with contractor slated for 12/19/17 to discuss findings. John Carnahan
10/4/2019 Cleanup Plan Approved A cleanup plan was approved this date. The cleanup of metals-contaminated soil is being performed by DEC as a DBAC service for the City of Delta Junction and the Delta Junction Trails Association. Field activities are scheduled to begin on October 7, 2019. Anne Marie Palmieri
10/7/2019 Update or Other Action DEC's cleanup contractor, Ahtna, mobilized to the site to begin the cleanup work on this date. Anne Marie Palmieri
10/10/2019 Site Visit Staff from DEC-Solid Waste, DEC-Contaminated Sites, and DNR conducted a site visit during the cleanup. Anne Marie Palmieri
10/17/2019 Meeting or Teleconference Held Staff from Ahtna, DEC-Solid Waste, and DEC-Contaminated Sites had a meeting to discuss complications regarding screening the soil during the cleanup. It was agreed that Ahtna could forego screening the soil as long as leachate modeling showed that this scenario would be protective and post-treatment analytical results meet the required thresholds criteria. Anne Marie Palmieri
11/19/2019 Document, Report, or Work plan Review - other DEC Contaminated Sites and Solid Waste staff reviewed and approved the Final fate and transport modeling memo. This memo showed through sampling and modeling that any leachate from the treated soil would not cause an adverse effect on groundwater at the landfill. Anne Marie Palmieri
12/3/2019 Update or Other Action DEC's contractor, Ahtna, started moving the treated soil to the landfill today. Anne Marie Palmieri
