3.  Conservation

Prepare and execute an Environmental Conservation Program to maintain access to land, air, and water for mission activities while sustaining the Installation’s natural and cultural resources in a healthy condition.  Ensure Base organizations and housing occupants are informed of conservation programs.  Ensure that all plans and programs are reviewed and updated for compliance and other environmental considerations and complement the Environmental Pollution Prevention Program. Review designs and acquisitions of new systems, including equipment and materials, to ensure that they do not create pollution or require hazardous materials whenever possible.

 

4.  Pollution Prevention

Prepare and execute an Environmental Pollution Prevention Program to eliminate or reduce, to as near zero as feasible, hazardous substance use and waste releases to the environment.  Include ozone-depleting chemicals, Environmental Protection Agency 17 industrial toxins, hazardous waste minimization, municipal solid waste, and affirmative procurement plans (minimizing use of hazardous materials).  Maintain inventory records of all chemicals required by the Emergency Planning and Community Right-to-Know Act (EPCRA).  Prepare and submit to the government representative EPA, and state officials an annual EPCRA/Toxic Release Inventory (TRI) reports.

5.  Compliance

Manage and execute the Environmental Compliance Program to comply with local, state, and federal laws and regulations.  This shall include tracking emissions and discharges from all Compliance Sites (e.g. equipment and users on the installation).  Maintain and keep current the Compliance Site Inventory.  Inspect and track areas that could create potential problems or releases of hazardous materials. Submit a monthly compliance report to the government.  Include permit actions, observations, testing, sampling, non-compliance, and corrective actions.

MaraTech personnel have extensive real world experience in environmental compliance, pollution prevention, and conservation issues – especially as it relates to the Air Force mission.  MaraTech has developed comprehensive environmental, and energy policy as it relates to pollution prevention, water quality and wastewater issues, air quality, hazardous material management, solid and hazardous waste management, alternative fuels, energy conservation, natural resources, and community relations.  MaraTech personnel are trained and experienced in using pollution prevention techniques to solve compliance and conservation problems in all environmental media (soil, air, and water).

The following notes some of MaraTech’s experience and accomplishments: 

Defense Environmental Restoration (DERA):   MaraTech manages the Installation Restoration Program at Hanscom AFB.

Because of waste disposal and resource management practices during the period that Hanscom AFB had a flying mission, the groundwater and soil in areas of Hanscom AFB and Hanscom Field became contaminated.

The USAF began implementing the Installation Restoration Program (IRP) at Hanscom AFB during the 1980s with initial surveys and records reviews to identify potentially contaminated sites.  This and subsequent discoveries have increased the number of IRP sites to twenty-two.   Of the 22 individual IRP sites with known or suspected hazardous material, 7 are National Priority List (NPL)/CERCLA regulated sites and fall under USEPA’s lead regulatory jurisdiction.  The remaining sites are either closed out or excluded from CERCLA.

Sources of this contamination include former fire training areas, a paint waste disposal area, and a jet fuel residue and tank sludge disposal area as identified above.  All of these IRP sites are on Hanscom Field.  Principal contaminants found in the groundwater, surface water and soil are chlorinated and aromatic volatile organic compounds (VOCs) associated with paints, solvents and fuels. 

MaraTech operates the Groundwater Treatment Plant (GWTP) consisting of two primary systems, air stripping towers and vapor phase granular activated carbon (GAC) units and their respective ancillary equipment.  The purpose of the groundwater collection, treatment, and recharge system is to treat contaminated water from confirmed contaminant release areas and from boundary interceptor wells.  The system consists of groundwater collection trenches and interceptor wells and boundary interceptor wells.  Groundwater, contaminated with VOCs is pumped from the various recovery points to a central treatment and treated using air stripping and vapor phase carbon adsorption.  The treated water is then pumped to on-site recharge basins or discharged to a nearby stream.  The system treats between 100 to 320 gallons per minute.  More than 1 billion gallons of groundwater have been treated and returned to the environment.

Conservation:  MaraTech personnel support the Conservation Program in the following activities.

Watershed:  MaraTech personnel set up a multitude of watershed protection and training programs for the Hanscom Air Force Base community.  MaraTech personnel coordinated and oversaw the clean up of the Shawsheen River vis-a-vis a program using 20 inner-city youths on natural surroundings and wetland protection.  MaraTech personnel drafted a grant request that received funds from the DoD for improving vegetation along the Shawsheen River.   For the past two years MaraTech has organized Shawsheen River clean ups involving the Boy Scouts and Cub Scouts and volunteers from CE.  MaraTech assessed and marked off several areas along the Shawsheen River that were damaged by large and abandoned debris.  Both clean ups helped remove over 300 lbs. of refuse from the Rivers ecosystem.  The Scout Troops were awarded merit badges for their time and service.

MaraTech personnel coordinated a sign installation program that identifies wetland protection zones.  MaraTech personnel have established working ties with the EPA, DEP, Merrimack River Watershed Council, and Shawsheen River Watershed Association, in developing a comprehensive Shawsheen River and Kiln Brook Watershed Management Plan.

MaraTech personnel have led various environmental community awareness programs including Earth Week educational booths, and environmental field studies for the children at Hanscom AFB’s schools.  MaraTech personnel coordinate educational workshops teaching household hazardous waste reduction alternatives, lawn maintenance, and chemical-free landscaping techniques.  Other MaraTech personnel experience in this area includes distributing Shawsheen River information to all libraries and Conservation Commissions within the Watershed community, and working with the Bedford planning board for the development of a town wide drainage study. Additionally, MaraTech personnel have provided technical guidance involving emergency response planning for the Shawsheen River Communities.

In 1997 Hanscom AFB, as part of the Upper Shawsheen Stream Team, was awarded an Adopt a Stream Program Plaque from the Department of Fisheries, Wildlife & Environmental Law Enforcement as a stake holder of the Shawsheen Watershed and a community leader.  MaraTech’s contributions helped Hanscom AFB’s Environmental Flight receive the award for Leadership and Protection to Restore the Shawsheen River Watershed from the Merrimack River Watershed Council in 1997.

Pollution Prevention (P2):  MaraTech personnel support the pollution prevention program to include submitting project proposals that reduce the environmental compliance burden through P2 technologies.  Some example projects include assisting in procuring a $1.2 million grant to replace two faulty 1000-ton industrial chillers with a new ozone friendly refrigerant system.  The new chillers attained EPA compliance and saved energy costs by over 20%.  MaraTech personnel led the design, development and installation of the first geothermal heated and cooled building in the Air Force.  The geothermal system eliminated all fuel oil usage and reduced the energy load by over 30%.  Additionally, the geothermal installation serves as a prototype for other AF industrial buildings in cold regions.  

MaraTech personnel helped implement several transportation initiatives to significantly reduce the amount of waste oil produced by the Transportation Complex.  MaraTech helped institute an oil analysis program combined with the installation of secondary oil filtration system on vehicles that prolongs oil changes by three times. The conventional disposal of oil filters was eliminated by providing filters that are simply washed for re-use.  Four waste oil heaters were also installed to burn oil in the winter that would normally be disposed as a regulated waste.  These initiatives reduce industrial vehicle oil consumption by over 40% and reduce the amount of hazardous waste generated and save $7,000 annually.

MaraTech re-engineered the industrial paint booth at the Transportation Complex to reduce Volatile Organic Compound (VOC) discharge by 90%.  The renovated booth eliminates 1,000 lbs. of VOCs being discharged into the atmosphere. MaraTech designed an industrial vehicle washing facility that cleans, filters, and recycles all the wastewater.  This facility potentially saves 90,000 gallons of wastewater each year.

MaraTech also helped convert the base photo laboratory from a wet chemical system to a digital system. The new process produces the same photo-quality work while eliminating 12,000 gallons of industrial waste disposal and saving $10,200 per year.

In an effort to eliminate Hanscom AFB’s waste streams, MaraTech personnel collated and analyzed hazardous waste disposal data as part of an Opportunity Assessment.  MaraTech personnel have assisted in collating and reporting technical environmental performance indicator data for HQ Air Force Materiel Command (AFMC) required monthly and quarterly submissions including the Deputy Under Secretary of Defense (DUSD) Environmental Data Calls.

Alternative Fuel Vehicles: MaraTech personnel helped institute an aggressive Alternative Fuel Vehicle Program.  We led the design, development and installation of the first Federal Compressed Natural Gas (CNG) re-fueling station in the Northeast.  MaraTech personnel drafted the design specification that was responsible for converting over 20% of Hanscom AFB’s vehicle fleet to CNG and electric power.  MaraTech personnel promoted electric and compressed natural gas vehicles in earth week presentations and in discussions with industry and Government groups.  MaraTech personnel remain the resident experts for providing technical support for the maintenance and enhancement of the Compressed Natural Gas Fueling System and the fleet of electric vehicles in use.

Hazardous Materials: MaraTech personnel serve as the primary function of the Hazardous Materials Pharmacy (HAZMAT) Program by authorizing requests and recommending product substitutions and/or chemical reductions.  All aspects of hazardous material approval is administered by MaraTech personnel including receiving requests, researching products (including substitutions), approving requests, tracking chemical purchases, inspecting facilities and recommending policy.  MaraTech personnel have a demonstrated history of monitoring hazardous materials and wastes, and substituting less hazardous chemicals that will still complete the mission.  MaraTech personnel have extensive experience in coordinating unused Class I ODSs to the Defense Supply Center Reserve.

One particular success story is MaraTech’s contribution to eliminating the use of Ozone Depleting Substances (ODSs).  MaraTech personnel created a prototype database for tracking the locations and quantities of ODSs and recommended a commercial off the shelf system when one became available.  Another example was the foresight to realize that the Hanscom School’s waste copier fluid, which is comprised of 95% methanol, could be diluted and used as windshield washer fluid or to displace water in air brakes.  The Transportation Complex accepted the 80 gallons of copier fluid and thereby saved the Government the $1,300 in disposal fees plus $300 for the cost of virgin methanol purchases.  All of these efforts have contributed to a successful Hazmat Program. 

Since MaraTech personnel have worked in the Hazmat, Hanscom AFB has always met HQ/AFMC quarterly chemical reduction goals.  Additionally, the Hazmat Team has been nominated for 66 ABW’s Annual Wing Awards in 1997, and in 1998, was honored with a Governor’s Proclamation during a ceremony at the State House.

MaraTech personnel conduct inventory/inspections, and research and collate chemical use and storage data in support of annual Emergency Planning and Community Right to Know Act (EPCRA) reports.  These EPCRA reports are in turn delivered to the State Emergency Response Coordinator and the Emergency Planning people in the towns of Bedford, Lexington, Lincoln, and Concord.

MaraTech developed a written training guide for the Hazardous Materials Management System (HMMS).  This training guide will allow HMMS users to successfully utilize HMMS to maintain and track hazardous materials using the cradle-to-grave capabilities provided within HMMS.

MaraTech established a working relationship with Ground Safety Personnel, wherein Safety has become involved in the Hazmat Approval Process, as directed in Air Force Instruction 32-7086, Hazardous Materials Management.

MaraTech personnel drafted a Consumer Commodity Waiver policy, eliminating the requirement for Hazmat approval to purchase over-the-counter hazardous materials, which had become burdensome to track.  Consumer Commodity products tend to be relatively harmless when purchased in personal size quantities.  This waiver policy has streamlined the Hazmat Approval Process and saved the customer, as well as Hazmat personnel, countless hours of review and approval time.

MaraTech personnel also implemented the new automated AF Form 3952, Hazardous Materials Authorization Request.  The automated request form has allowed customers the freedom to submit requests directly from their personal computer.  The automated request form has also allowed the Hazmat to maintain historical records of all hazmats purchased since the launch of the automated form.

Recycling: MaraTech personnel provide technical support to Hanscom AFB Qualified Recycling Program (QRP) by researching and implementing new innovative recycling programs for the Air Force.  MaraTech personnel provide integrated solid waste management for Hanscom AFB recycling and refuse program by daily monitoring of recycling programs and assistance in the development of local, state, and federal reports.  We provide briefings on recycling issues to management, the QRP, facility managers, outside federal, state, and local organizations.  These recycling efforts have been documented to save the Air Force at least $48,000 per year in avoided disposal costs.

MaraTech personnel implemented a toner cartridge-recycling program at Hanscom AFB.  Since the inception of the program, the government has saved approximately $12,780 in Hazardous Waste disposal costs.  Approximately 3,195 toner cartridges have been recycled, thus avoiding 6,390 pounds of plastic from being dumped in a landfill. 

MaraTech personnel oversee the expansion of Hanscom AFB’s compost program through new equipment purchase and creative technique recommendations.  MaraTech personnel assist in the daily management of an office white and mixed paper-recycling program that has increased paper recycling by 50%.  MaraTech personnel implemented the installation of two sawdust recovery units that collect 6 tons of sawdust for recycling.  MaraTech personnel also implemented a scrap metal recycling program on Hanscom AFB.  This program collects over 200 tons of mixed metals annually. 

MaraTech personnel coordinated and supervised the construction of a Recyclable Collection Center for the collection of cardboard, construction debris, and scrap metal materials on Hanscom AFB.  This collection center separates construction debris materials for better recycling at a lower cost and increased cardboard recycling by 25%.  MaraTech personnel also assisted in establishing an Affirmative Procurement Plan so that more products made from recycled materials are purchased.

MaraTech personnel designed and helped create informational Recycling signs and pamphlets for office buildings at Hanscom AFB that generate moderate amounts of white and mixed/colored office paper.  These two office recycling programs have helped recycle an average of 18,660 lbs. of paper per year. 

Compliance:  MaraTech personnel support the environmental compliance program by performing the following activities. 

Spill Response: MaraTech personnel provide environmental spill response advice on various incidents to include minimizing environmental damage and reporting to spill regulatory officials.  For example, MaraTech personnel responded as part of the Environmental Flight team to three, high impact sewage leak situations.  MaraTech personnel insured that no sewage contaminated the storm drain system.  A MaraTech representative is an invited member of the Disaster Control Group for Hanscom AFB.  This group identifies potential threats to the environment during exercises and actual situations. 

Asbestos Activities: MaraTech personnel have proven experience in almost all aspects of asbestos abatement projects including asbestos inspection/surveys, planning, estimating and designing abatement projects, management planning, and serving as a contract inspector to ensure compliance with State and Federal regulations.   

MaraTech personnel perform asbestos inspection/surveys including investigating building records for documentation on the presence of asbestos containing material (ACM), and inspecting buildings for friable and non-friable suspect asbestos containing materials.  MaraTech personnel are responsible for taking samples and having them analyzed for asbestos.  MaraTech personnel also assess the condition and location of the ACM and other characteristics of the building.  After reviewing the results of the inspection and physical assessment reports, MaraTech personnel determine the hazard posed by the ACM, selects and recommends proper control/response options. 

MaraTech personnel plan, estimate, design, and inspect an average of 20 asbestos abatement projects per year.  MaraTech personnel also perform technical reviews on proposed engineering projects for asbestos issues.  These projects have ranged from small-scale removal to large-scale abatement projects.  For all asbestos abatement projects, MaraTech personnel have developed a projects facility folder to include asbestos surveys, procurement actions, cost estimates, Statements of Work, State notifications, contractor’s license, daily site logs, final air clearance reports, waste shipment records and invoices.  MaraTech personnel maintain the Asbestos Management Plan and Operations and Maintenance Program.  MaraTech personnel administer, monitor, and maintain the Asbestos Abatement IDIQ contract and the Asbestos Inspection/Survey and Abatement Project Monitoring contract. 

Poly-chlorinated biphenyl (PCB) Activities:  MaraTech personnel have coordinated sampling and inventoried electric transformers and ballasts.  Furthermore the sampling results were compared against regulatory levels and the inventory tracked their disposal when necessary. 

Hazardous Waste Activities: MaraTech personnel have demonstrated experience in assisting environmental engineers and staff with hazardous waste management activities including, inspections, inventories and management plan updates.  MaraTech personnel perform quarterly inventory and characterization of hazardous waste so that the hazardous waste contractor can properly dispose of the waste.  MaraTech personnel perform monthly hazardous waste inspections for 38 Initial Accumulation Points and two, 90-day Accumulation Sites at Hanscom AFB.  MaraTech personnel maintain a file of all monthly inspection reports and perform mandatory annual reviews and updates to the Hazardous Waste Management Plan.  MaraTech personnel ensure Annual Hazardous Waste training is provided for all hazardous waste managers.

Rideshare Activities: MaraTech personnel assisted in the development of Hanscom AFB’s Ride-Sharing Program in order to reduce single occupant commuter vehicle use.  MaraTech personnel conduct annual commuter surveys, and educate Base personnel by submitting articles to the base paper and distributing pamphlets during Earth Week events.  MaraTech personnel serve as a contact for questions and concerns regarding the Ride-Sharing Program.  The ride-share data is collated and delivered to the Commonwealth of Massachusetts and to the State Ride Share Contractor.  MaraTech personnel have collected the data and filled out the annual Commuter Reduction Status Report to the DEP.  MaraTech developed a management action plan that advanced a successful commuter ride share program.  MaraTech helped to put into practice the new policy of reimbursing Hanscom AFB employees who use mass-transit.  MaraTech developed Internet technology that promotes policy and information on ride-matching services, vanpooling, and incentives for using public transportation.  A virtual bulletin board was added to the Environmental Flight’s web site so that private carpooling can take place easier.  MaraTech personnel remain continually informed of the Route 3 highway expansion and construction efforts and often serve as the focal point for community relations on this subject.

Air Quality Assessments:  MaraTech personnel have established experience in assisting environmental engineers and staff with Air Quality Assessments.  MaraTech performs quarterly air quality assessments for emission control on boilers at the clinic and the central steam plant, paint spray booths, dust collection cyclones systems, and cold cleaning parts washers. MaraTech also performs inspections on fuel dispensing (Stage II Vapor Recovery systems) at the Auto Pride service station and Vehicle Maintenance.  MaraTech has extensive experience in coordinating annual Underground Storage Tank (UST) electronic leak detection certification, and annual pressure testing of product lines and tank per 527 CMR 9.  MaraTech provides the quarterly inspection reports, maintains and files reports by air source.  MaraTech prepares an annual air emission statement and source registration for stationary sources, and Annual Compliance Certification pursuant to the Clean Air Act (CAA) Title V.

MaraTech personnel have successfully coordinated indoor air quality assessments related to radon and toxic mold exposure.  MaraTech has recommended remediation techniques based on scientific and construction knowledge.

Facility Engineering Support:  MaraTech personnel work extensively with Base civil engineers to provide environmental expertise on the design and construction of a wide range of renovation and new construction projects.  Such items include commenting on proposed engineering projects for air quality, asbestos, refrigerant, affirmative procurement, and recycling issues.  MaraTech personnel serve as Environmental Compliance Assessment and Management Program (ECAMP) inspectors for various environmental protocols during the annual compliance assessments.  In addition, MaraTech personnel have experience in design, construction, renovation, maintenance, repair and management of facilities and housing units along with their accompanying infrastructure.

Energy Management/Utility Engineering Support:  MaraTech personnel provide technical support for both energy management and utility engineering to Hanscom AFB.  MaraTech personnel administer the base-wide Energy Savings Performance Contracts, and continuously update data for quarterly and year-end energy reports.  MaraTech personnel provide mechanical and energy engineering support to Civil Engineering's Design section for all applicable projects.  MaraTech personnel provide utility budget reports and projections based on market conditions.  MaraTech personnel determine what is the most efficient way to fuel the production of steam at the central steam plant depending on projected costs and environmental constraints.  For example, during the month of February MaraTech personnel determined that burning 84,000 deca-therms of Natural Gas versus burning 84,000 Million British Thermal Units of #6 Heating Oil would save the government $70,000. 

MaraTech personnel conduct all reimbursement-billing operations for Hanscom AFB tenant organizations. Also any discrepancy in metering data is verified and provisions are made for any needed meter repair. 

MaraTech steered the base's energy situation during the difficult time when Enron, the base's electricity provider, went bankrupt.  Working with the General Services Administration, MaraTech personnel conducted technical review of the bidders so that a new electricity provider contract could be awarded.  MaraTech’s understanding of the deregulated utility industry and experience with negotiating large commercial contracts, allowed Hanscom AFB to secure a new contract that will result in $400,000 savings per annum.  Similarly MaraTech is providing technical support for the negotiation of a new natural gas supplier contract for both military family housing and the central steam plant.

MaraTech personnel have discovered that potential energy rebates for both electricity and natural gas were not pursued for the base pool project.  MaraTech has subsequently submitted applications and anticipates significant financial incentives.  MaraTech continues to provide solid oversight with the base-wide energy management system and is actively reviewing upgrades to the utility metering system base-wide.

Information Technology Support:  MaraTech personnel provide information technology expertise and product support to the Environmental Flight in the areas of the Local Area Network (LAN), and NT/Win 2000 Servers and software for approximately 20 clients.  The software includes Microsoft Office, MapInfo Geographic Information System, the Hazardous Materials Management System, Oracle Database systems (Air Force Civil Engineering System, Command Core, Environmental Quality Database, Air Performance Information System), and other necessary systems.
