Napaskiak Remediation Support – Alaska Region 2024

Introduction The Bureau of Indian Affairs (BIA), Alaska Regional Office (ARO), Division of Environmental and Cultural Resources Management (DECRM) is requesting proposals, to enter into a contract for a preliminary investigation/ site assessment of soil and groundwater contamination within the Village of Napaskiak. The purpose of this contract is to conduct a preliminary investigation/ assessment and remediation at the old school site within the Village of Napaskiak in order to characterize the contamination and design a remediation plan.

The scope of work includes research of historic documents, site reconnaissance, identification of contamination, geotechnical investigation, risk evaluation, permitting, field work, sampling, analysis, data evaluation and additional activities to determine the quantity and quality of contaminants present at the site. The scope of the investigation shall provide information sufficient to identify potential liability and risk associated with environmental and public health considerations concerning the property. In addition, the site characterization will allow managers to plan further investigations, if required, to determine cleanup requirements and design a cleanup action in accordance with the Alaska Department of Environmental Conservation (DEC), federal and tribal laws and regulations.

Background

Napaskiak is located within the Yukon‐Kuskokwim Delta on the south bank of the Napaskiak Slough, 6 miles south of Bethel and 400 miles west of Anchorage, Alaska. The old school was located approximately 150 feet south of the slough. The geographic description for the Napaskiak school is: Seward Meridian, Township 7 North, Range 71W, Section 8, of the United States Geological Survey. Previous reports documented DRO and PAH contamination in the vicinity of the site, with unknown extent and DRO concentrations up to 26,100 mg/kg. A 2012 report from the site indicated: approximately 1,000 CY of fuel contaminated soil, an abandoned sewage lagoon (25’ x 35’, 25 cy, 18,000 gal) and groundwater contamination.

The Environmental program ensures BIA’s compliance with environmental laws and regulations related to Native Allotments, Trust properties and BIA-funded projects. Among the support provided are contaminated site characterizations, remediation, groundwater sampling and laboratory analysis. The intent of the project is to characterize contamination at the site and determine if impacts could pose a threat to the environment and/or human health, as well as if existing conditions may violate environmental regulations.

The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERLCA), also known as Superfund, was created to provide the authority and a source of funding for cleaning up hazardous substances released into the environment. A basic goal of Congress in writing CERCLA was to make those who are in control of property (owners and operators) contaminated by hazardous substances financially responsible for their clean up.

Under CERCLA; you are potentially liable for clean up if you were a past owner/lessor/lessee of property when it was contaminated, are a current owner/lessor/lessee of contaminated property or if you buy or lease property already contaminated by someone else. Current property owners who did not cause contamination may still be financially liable for contamination peter.dunlevy Cross-Out associated with their land because of CERCLA's provisions of strict liability for contamination, and joint liability among all potentially responsible parties (PRPs).

The Superfund Amendment and Reauthorization Act of 1986 (SARA) amended CERCLA and created an "innocent purchaser" exception to owner responsibility. The current legislative, regulatory, and judicial climate has provided notice to property buyers, developers and lending institutions of the environmental risks associated with purchasing property. This risk, as well as the "innocent purchaser" defense, has created the need for environmental site assessments.

Required Tasks Conduct a contaminated site characterization and begin remediation efforts within the Village of Napaskiak. The Contractor(s) shall furnish the necessary personnel, materiel, equipment, services and facilities to perform the work for successful completion of the following project objectives:

1. Planning and Project Management: Conduct project kick-off meeting and a planning meeting with BIA; develop work plan, schedule for the tasks and interim milestones.

2. Field Work: Obtain direct, in situ information that connects recognized environmental conditions to the property and delineates the area contaminated above regulatory cleanup levels. Also, if prior information is confirmed work may include excavation and in-situ landfarm treatment of approximately 1,000 CY of fuel contaminated soil, dewatering and quicklime treatment of the sewage lagoon (25’ x 35’, 25 cy, 18,000 gal) and groundwater monitoring.

3. Interviews and Records Review: Obtain information from past and present owners and occupants along with tribal, state and/or local government officials to connect recognized environmental conditions to the property; and obtain and review records and documents for the property that may identify recognized environmental conditions.

4. Report: The report must identify the environmental professional and others whom conducted steps 2 and 3 listed above, support findings and ensuing opinions with documentation, and use enough detail to allow another party to reconstruct the work that was performed and come to the same conclusions.

Task 1: Planning and Project Management

The contractor(s) will lead a project kick-off meeting with BIA within two weeks of the contract award to introduce the Contractor's Project Manager and key BIA personnel (Project Manager, Contracting Officer). Within one month after the award, a planning meeting will occur where the work plan, including schedule for the task elements will be identified, and interim milestones will be agreed upon and accepted by DEC. Key Contactor personnel/subcontractors will participate in the planning meeting. The Contractor will prepare materials and minutes for these two meetings. Minutes are due one week from the date of the meeting for review and comments and finalized 10-days after meeting dates. The Contractor should plan for one additional meeting during the period of performance following submittal of the draft final report.

In preparation for the planning meeting, the Contractor shall:

• Collect and review existing data and files located on the DEC’s Contaminated Sites website

• Prepare a draft work plan and submit to BIA and DEC for review and approval peter.dunlevy Sticky Note Changed to: ...delineates the area contaminated above regulatory cleanup levels and groundwater monitoring. Also, confirm if prior information regarding poterntial excavation of approximately 1,000 CY of fuel contaminated soil with local landfarm treatment and dewatering/ quicklime treatment of the sewage lagoon (25' x 35', 25 cy, 18,000 gal) is still accurate and warranted

• Prepare a draft health and safety plan (HASP) in accordance with 29 CFR 1910.120 to ensure worker protection

• Prepare a draft notice to Native Corporation/Village advising them of the proposed site visit and sampling

Task 2: Interviews and Records Review

The contractor shall contact and interview past and present owners and occupants as well as, tribal, federal, state and/or local government officials to determine and document any contaminants issues associated with the property.

Historical records are also searched to determine historical ownership and occupancy of the subject property for the past 50 to 100 years. Chain-of-title documents are obtained from a title company and are reviewed for property ownership. Because property owners are not always property occupants, historical maps and city directories are viewed for property occupancy.

Historical references include village directories and Fire Insurance Maps. Available aerial photographs are also reviewed for historical and current property occupants and uses. Aerial photographs are often available for the past 50 to 60 years and property development can be verified by reviewing them. Public agency files are then reviewed for information on the subject property. Environmental regulatory agency files are reviewed for documentation of hazardous substance contamination and/or regulation of the subject property. Files and site lists are reviewed at the Environmental Protection Agency (EPA).

Local village, borough, native corporations and agencies such as fire departments, health departments and public works departments' records are also reviewed. These local agency files may contain information on: building and commercial utilities permits (water, sewer and electrical permits), fire department inspection records/permits for buildings and underground storage tanks; information on zoning, adjacent landfills and electrical transformers. Interviews with representatives of these agencies are conducted to expand on the information found in file reviews.

Task 3: Field Work

The Contractor will plan field work with BIA personnel to document current site conditions, inspect known and potential sources of contaminants of potential concern (COPC) and delineate the area contaminated above regulatory cleanup levels. If confirmed, probable excavation and in-situ landfarm treatment of approximately 1,000 CY of fuel contaminated soil, dewatering and quicklime treatment of sewage lagoon (25’ x 35’, 25 cy, 18,000 gal) and groundwater monitoring. The field work will be coordinated with local tribal governments to ensure adherence to any restrictions.

A thorough inspection of the site is usually conducted first to familiarize the assessor with the physical parameters of the property and the surrounding properties. During this inspection, the assessor inspects the property and adjacent properties from the property lines for signs of obvious contamination such as discolored soil, dead vegetation, underground tank vents, leaking drums or other containers. The assessor also takes note of all current property users and any relevant activity that may have impacted the property being assessed. These observations are documented with photographs and GPS coordinates for the final report. If contamination is peter.dunlevy Cross-Out peter.dunlevy Sticky Note Changed to: The Contractor will plan field work with BIA personnel and DEC approval to document current site conditions, inspect known and potential sources of contaminants of potential concern (COPC), delineate the area contaminated above regulatory cleanup levels, conduct groundwater monitoring and reconnaissance/ information gathering to plan future remediation actions. Groundwater monitoring wells will have to be installed. Discussions with AK DEC during planning will help guide the GWM, however BIA assumes five wells in total—two uphill, two downhill and one at the central point. GWM will require two sampling events in the first year (spring and fall). Analytical samples are expected to be collected. BIA anticipates 12 soil and 10 water (five-spring, five-fall). Contaminants of concern are DRO, PAH and VOCs. Also, confirm if prior information regarding potential excavation of approximately 1,000 CY of fuel contaminated soil with local landfarm treatment and dewatering/ quicklime treatment of the sewage lagoon (25' x 35', 25 cy, 18,000 gal) is still accurate and warranted. BIA anticipates duplicating the sewage lagoon sampling done in 2012 with three locations/ samples each for chemical oxygen demand and biological oxygen demand (six samples). The field work will be coordinated with local tribal governments to ensure adherence to any restrictions.

identified or suspected, soil and water samples (as appropriate) will be collected and analyzed as necessary to characterize the contaminated area. Field work will be dependent on weather conditions.

Task 4: Reporting

Based on the site inspection, field work, interviews, historic records and public agency file review; a report is prepared that summarizes the findings and presents recommendations for further field and laboratory work, if required.

A draft report will be submitted for review by BIA and DEC within 45 days following completion of the field work. The contractor shall schedule a joint work session to review the draft report and note comments for incorporation into the 90% submittal to expedite the review process. Following the final review and approval of the draft documentation by BIA and DEC, the contractor shall prepare the final report at 100% completion. This should include an electronic pdf version and three hard copies.
