Problems/Comments

Petroleum contaminated soils resulting from logging operations have been collected and are being bioremediated in a gravel pit. Samples were taken 8/28/1991 by ADEC for analysis at Douglas Lab. Klukwan was operator during period of contamination. Operation has just been turned over to ITT Rayonier. 10/21/15: The current RP is Goldbelt Inc. Contamination at the Hobart Bay Logging Camp was first reported to DEC in 1991 and the site was listed on the Contaminated Sites Database in 1993. Since that time, various assessment and cleanup activities have occurred sporadically over the years and cleanup continues today. According to ADEC records, there were five source areas: 1. Bulk fuel AST farm 2. Passive bioremediation cell (biocell) 3. Residential camp oil pipeline 4. Vehicle maintenance shop 5. Generator building – Closed A work plan was approved in 2014 to address the source areas but no funding for the work was available. Work is expected to take place in May of 2016.

Rachael Petraeus
5/19/2022	Site Characterization Workplan Approved	The ADEC approved the "Final Work Plan, Hobart Bay Logging Camp Site Investigation", dated April 2022. Field activities will occur in summer 2022 and will include: 1). Analyzing soil samples from the historic bioremediation cell to determine whether DRO contamination in soil is now below ADEC cleanup levels. 2). Excavating contaminated soil near the sump in the Bulk Fuel AST and creating a new bioremediation cell in which to remediate newly excavated soil.

3/1/2023	Document, Report, or Work plan Review - other	The DEC provided comments in response to the "Draft Report Hobart Bay Site Investigation", dated January 2023. The DEC is asking for the report to be updated and re-submitted for review.	Flannery Ballard
5/22/2023	Site Characterization Report Approved	The DEC approve the Final draft of the 2022 Site Investigation. This report summarized the site investigation activities that occurred in three areas of concern: the Bulk Fuel AST Farm, the Historical Bioremediation Cell, and the Vehicle Maintenance Shop, as well as the creation of the new bioremediation cell, the Bulk Fuel AST Bioremediation Cell. 133 CY of petroleum impacted soil was excavated from around the sump and pump house at the Bulk Fuel AST Farm, and placed in the new biocell. The excavation was completed to bedrock. Confirmation samples indicated that there are exceedances of DRO, naphthalene, 1,2,4-trimethylbenzene, and 1,3,5-trimethylbenzene above MTG in multiple soil samples. Two soil samples were collected from the Historic Biocell; only one exceeded for DRO at 430 mg/kg. Finally, the four floor drains in the Vehicle Maintenance Shop were investigated. A sample from the bend in the pipe in each floor drain was collected and analysed for GRO, DRO, RRO, VOCs, PAHs, PCBs, EDB, and RCRA metals. Results indicated exceedances above max allowables for DRO, RRO, above HH for arsenic and lead, and exceedances above MTG for cadmium, tetrachloroethylene (PCE) , naphthalene, and multiple other VOCs and PAHs.	Flannery Ballard
8/21/2024	Site Characterization Workplan Approved	The revised Soil Sampling and Analysis Plan Logging Camp Maintenance Shop, dated July 29, 2024 is approved with additional comments provided in the final comment matrix. RP excavated around the maintenance shop to locate the maintenance shop outfalls. Two discharge lines have been located, and DEC told RP to stop all excavation activities until a QEP is on site to complete site characterization. Coordination with EPA is required for class v injection wells.	Stacee Henderson
