Village of Gulkana Strategic Project Implementation Plan (SPIP)

Client: Gulkana Village Council

Project Objectives: In 2007, the Gulkana Village Council of Gulkana, Alaska, contracted with Bristol to assist in obtaining Native American Lands Environmental Mitigation Program (NALEMP) funding to clean up affected Native lands. Bristol conducted record searches, interviews with elders, and a site visit to identify potential impacts for NALEMP funding and to prepare the SPIP.

Together, Bristol and the Village Council identified five sites of concern comprising approximately 50 acres of Native land that contained unsafe structures, as well as surface and buried debris and potential areas with buried drums from past military operations. For each site, Bristol determined the primary concern, ownership, military impact and proposed action, and tabulated approximate cost of cleanup.

Project Activities:

√ Remote Site Work
√ Historical Research
√ Identifying Tribal Values & Concerns
√ Site Assessment
√ Funding Assistance

East Creek Hatchery Soil Remediation

Client: Choggiung, LTD.

Project Objectives: 
In 2006, Bristol Environmental Remediation Services was contracted by Choggiung, LTD. to prepare a Site Characterization Report and propose a remediation treatment for an 800-cubic-yard diesel- contaminated soil stockpile.  The soil had been stockpiled as a result of a fuel spill cleanup which occurred at the East Creek Hatchery near Dillingham, Alaska in 2001.  The site is in a remote area with seasonal vehicle access. 

Bristol sampled the stock pile to establish existing fuel contamination concentrations and prepared a Site Characterization Report which was submitted to the Alaska Department of Environmental Conservation (ADEC).  Based on the report, ADEC determined no further action was required at the site, except for the treatment or disposition of the remaining contaminated soil stockpile.

Bristol conducted a remediation action using the land farm remedial treatment.  Bristol ensured that access was controlled at the site, that safety precautions were adhered to, and that site closure sampling was completed.  ADEC issued a no further action notice to the client upon completion of the project.

Project Activities:

√ Site Characterization
√ Cost Effective Remediation Alternatives
√ Environmental Remediation
√ Regulatory Coordination
√ Remote Site Work & Logistics

Representative Water Quality Projects

Liberty Bell Property – Surface Water Quality Environmental Baseline Study

Client:  Metallica Resources, Inc.

Project Objectives: In 2007, Bristol Environmental Remediation Services conducted a surface-water quality baseline study for a mineral exploration project at a former mine site located on the north flank of the Alaska Range, approximately 70 miles southwest of Fairbanks, Alaska.  Access to the sampling areas was by an all-terrain vehicle (ATV) and/or on foot.
The objective of the Surface Water Quality Study was to define the chemical characteristics of the freshwater surface streams that could be potentially impacted by development in the prospect area. 

Bristol designed a sampling approach; determined the number of environmental samples required to provide a representative study; and identified the most appropriate environmental data parameters to collect at the site.  Quality control procedures were identified and implemented.  Bristol ensured the safe transport of samples from a remote location to an analytical laboratory. 

Bristol provided the client with a surface water quality report comparing the results of field and laboratory analyses to the water quality regulatory criteria.  The project was completed within budget and on schedule.

Sun Property – Surface Water Quality Environmental Baseline Study

Client:  Alaska Earth Sciences, Inc.

Project Objectives:  In 2007, Bristol Environmental Remediation Services conducted a surface-water quality baseline study for a remote mineral exploration project in the Brooks Range near Kobuk, Alaska.  The objective of the Surface Water Quality Study was to define the chemical characteristics of the freshwater surface streams that could be potentially impacted by development in the prospect area. 

Bristol designed a sampling approach; determined the number of environmental samples required to provide a representative study; and identified the most appropriate environmental data parameters to collect at the site.  Quality control procedures were identified and implemented.  Bristol ensured the safe transport of samples from a remote location to an analytical laboratory.
