Air National Guard Support Services

Environmental, Engineering, Professional, & Remediation 

Under multiple Air National Guard Bureau contracts, PEER successfully completed nearly 300 delivery orders for the Air National Guard that included: multi-media investigations, soil and groundwater remediation, monitoring, compliance, and reporting.  Brief summaries of key projects are provided below. 

Remedial Action and Project Closeout, Gabreski Air National Guard Base, Westhampton Beach, NY

The issue faced during this part of the project was that metals-contaminated soils were found in the immediate vicinity of the planned extension of an aircraft maintenance hangar at the Gabreski Air National Guard Base.  PEER negotiated remediation strategies with the state regulators in order to expedite the field activities.  The Remedial Action (RA) consisted of excavating and recycling contaminated soils via asphalt batching.  Confirmation soil samples were collected to verify the complete removal of metals-impacted soils.  The site was restored to its original condition by using the techniques of backfilling, re-seeding and mulching.  After completing the RA, PEER recommended No Further Action.  All stakeholders concurred and the project was completed within the period of performance.

Remedial Investigation, Coos Head Air National Guard Station, Coos Bay, OR

PEER conducted a Remedial Investigation (RI) to delineate contamination in soil and groundwater at nine areas of concern and to provide data for evaluating remedial action alternatives.  The Coos Head property had previously been transferred to a Federally-recognized Native American Tribe and PEER lead intense negotiations between tribal members and other stakeholders due to the cultural importance of the property.  The Remedial Investigation consisted of an extensive subsurface and hydrogeological investigation.  Human Health Risk Assessment and Phase I and II Ecological Risk Assessment were also performed.  An RI Report was prepared to document the results, conclusions and recommendations of the investigation and risk assessments.  Remedial Action was recommended at four areas of concern due to potential unacceptable risks to human health and the environment.

Remedial Action Construction, Oregon ANG, Portland, OR 

PEER performed Remedial Action Construction at three sites.  The remedial action was implemented to address groundwater impacted by several chlorinated solvents.  Six rounds of potassium permanganate injections were performed. The number of injection points for each round ranged from 114 and 650 points, with the amount of oxidant injected ranging from 34,200 to 195,000 gallons. The initial injection rounds addressed the dissolved phase “hot spots” while subsequent rounds addressed the remaining contamination. LTM was conducted to assess the success of the chemical oxidant treatment and the action of natural attenuation on residual dissolved chlorinated contamination.  Additional groundwater monitoring wells were installed to provide additional data points to assist in the determination of the lateral extent of the dissolved phase contamination and also as Point of Compliance. The project was completed and successfully closed at the end of the period of performance wells.

Remedial Investigation/Feasibility Study, McGhee Tyson ANG Base, Knoxville, TN

PEER conducted a Remedial Investigation/ Feasibility Study (FS) at four sites to determine the nature and extent of contamination in overburden soil, and in shallow and semi-confined groundwater (karst). Human Health and Ecological Risk Assessments were also performed. The risk assessment results indicated that contaminants identified in soil and groundwater did not pose unacceptable risks to human health or the environment.  Remedial alternatives were screened against evaluation nine criteria and the most technically appropriate and cost-effective Remedial Action alternatives were selected to address contamination.  The FS was made available for Public Review and a Record of Decision was prepared to document the selected remedial alternatives.

Site Assessment, Former Underground Storage Tank (UST) Site, McEntire ANG Station, Eastover, SC

PEER conducted a Site Assessment at a former UST site to evaluate the nature and extent of contamination in soil and groundwater.  Low-levels of soil contamination were detected in the vicinity of the former UST.  Fate and transport modeling were performed to determine contaminant persistence and migration potential.  Fate and transport modeling indicated that the site posed no unacceptable risks to human health or the environment, No Further Action was recommended and the ANG obtained regulatory concurrence for site closure.

Environment, Safety, and Occupational Health Compliance Assessment and Management Program (ESOHCAMP) at Multiple Air National Guard Installations

PEER performed multiple compliance assessments for the ANG’s Environment, Safety, and Occupational Health Compliance Assessment and Management Program (ESOHCAMP).  ESOHCAMP is a comprehensive self-evaluation and program management system for achieving, maintaining and monitoring compliance with environmental, occupational health, ground safety and weapons safety laws, regulations and directives at ANG installations.  The purpose of the assessments was to ensure the ANG’s compliance with all applicable federal, state and local laws regulations, Department of Defense, Air Force and Air National Guard instructions and policies, and Presidential Executive Orders.

The assessments included: an assessment of aircraft and vehicle maintenance operations, bulk fuel storage areas, hazardous waste storage areas, wastewater and storm water management, weapons and bombing ranges, weapons storage areas, vehicle maintenance facilities and hazardous materials storage areas.

The compliance assessments consisted of: an in-brief meeting with installation managers, assessing the installation's environmental management program, conducting visual inspections of all installation operations and facilities (including tenant organizations), preparing summaries citing regulatory deficiencies and conducting an out-brief with base personnel to discuss non-compliance findings.  At the completion of each assessment, the assessment team generated a web-based report citing regulatory deficiencies and potential root causes.  Using the same web-based program, installation managers provided their plan of action for addressing each finding.

West Virginia Army National Guard, Various Locations

PEER performed Phase I Environmental Site Assessments (ESAs) at properties acquired to construct Readiness Centers ranging in size from five (5) to 350 acres. The purpose of the ESAs was to determine the presence or likely presence of any hazardous substances or petroleum products. PEER conducted interviews with Army Guard personnel, local government officials and property owners. The team searched USEPA and state databases and reviewed aerial photographs, Sanborn and topographic maps and city directories. PEER’s inspections identified two parcels with potential contaminants. ‘De minimis’ conditions were identified for small releases and normal use of herbicides and pesticides.

During the execution of each task order under the National Guard Bureau contracts, PEER incorporated practices to reduce environmental impacts.  These practices included: using field techniques to reduce the volume of investigation-derived wastes, minimizing vehicle idling to reduce fuel consumption and air emissions, and conducting recycling to reduce the volume of trash generated during field activities.
