EMR conducted an environmental restoration project with both RCRA and CERCLA regulatory components that included wetlands remediation and the installation of a solid waste landfill cap at the end of an active military runway. The project was performed as the final phase interim action at the Warner Robins Landfill 4 Superfund site. EMR first completed corrective actions at the SWMU 23 landfill site by remediating hot spots and installing an earthen cap. After SWMU 23 was appropriately capped, EMR mobilized to the OU2 wetlands and began remedial actions. Site drainage control measures were installed in the wetlands to facilitate water management of saturated soils contaminated with arsenic, cadmium, lead, and silver. Once contaminated soils were excavated from the OU2 wetland areas, the site control measures were removed, restoring proper wetland hydrology. Protection of the OU2 wetlands was the main focus of the Georgia Department of Natural Resources, Georgia Environmental Protection Department, Region 4, and the public, who were closely monitoring the project.

EMR designed a 3,250 square foot addition to Eglin's Fire Station #1 apparatus bays, including a five-stall garage 52' x 100' with five 15' wide x 17' high doors. Original size of the fire truck five-stall garage was 25' long by 75 feet wide with 12' x 12' door openings. The larger stall doors were required to accommodate the multi-million dollar fire trucks that are designed to attend to flight line/air craft fires and emergencies and are larger than street regulations. Demolition of the existing roof, two main supporting walls, storage room and a training room was necessary to complete the design and construction.

EMR responded to the Deepwater Horizon Oil Spill on April 29, 2010, just 9 days after the offshore oil drilling platform exploded, releasing thousands of barrels of oil into the Gulf of Mexico each day. EMR had 350 people on the Gulf Coast responding to the oil spill comprised of 200 EMR employees and 150 subcontracted personnel. Personnel were engaged as Health & Safety leads or observers and scientists serving as environmental sampling leads or field samplers. EMR's Health & Safety organization was responsible for ensuring that those fighting the spill, both on- and off-shore, were properly trained and were complying with the Health & Safety Plan. The EMR team was deployed to 57 sites in the Gulf, from Intracoastal Louisiana to Tallahassee, Florida. Twenty-five percent of the workforce was on water vessels, including jackrigs as far as 100 miles offshore, work barges, fast boats, and deep water drilling platforms. The Health & Safety staff members were imbedded with other contractors performing a wide range of cleanup tasks, including beach cleaning, marsh cleaning, boom deployment, oil skimming, boat cleaning and decontamination, and related construction and repair activities. The sampling team performed sampling and analysis of soils, sediments, surface water and air to monitor changing conditions for wildlife, local residents and oil spill workers.

EMR, along with our teaming partner Project Engineering Consultants (PEC), completed a cultural resources inventory of 5,421 acres of land located in Tooele County, Utah. A total of 27 sites were encountered during the course of fieldwork, six of which were previously documented and revisited. Eleven previously undocumented prehistoric sites of unknown cultural association consisting of open lithic scatters were recorded. Nine of the new sites noted during the course of field work were historic in nature. The sites were combinations of trash- and can-scatters, with a few exhibiting possible structural elements. Fourteen of these sites were determined to be significant finds and recommended as potentially eligible for the National Register of Historic Places.

EMR is in the second year of a nine-year performance-based remediation contract conducting remedial investigation studies, UST closures, geophysical surveys, Corrective Action Plans, site remediation, long-term monitoring, and development of Optimized Exit Strategies (OES) at 49 different sites regulated under both RCRA and CERCLA components. Contaminants include petroleum hydrocarbons, volatile organic compounds, chlorinated solvents, heavy metals, and PCBs. Remedial strategies include source removal, in-situ bioremediation (aerobic and anaerobic), in-situ chemical oxidation, and landfill cap management with long term monitoring. Within the first year of the contract, EMR successfully met the objective of Site Closure of two sites. The overall objective is to achieve Site Closure of 32 of 49 sites by 2019. For sites not anticipated to be closed within the nine-year period of performance, EMR is developing OES to expedite closure and provide the Air Force with significant lifecycle cost savings.

EMR responded to a year-end request to design and build a replacement for the oldest standing dam in Georgia: Big Lake Dam. Upon receiving the call from the Air Force Reserve Command (AFRC) at Dobbins, EMR assembled a team of designers, suppliers, and potential subcontractors and mobilized. Within two days of the call, the site walk was completed. Two days later, conceptual design and pricing was completed, including firm subcontractor costs. The design included replacement of the existing dam with a 530 lineal foot Roller Compacted Concrete (RCC) dam constructed with 6,500 cubic yards of RCC, gravity buttresses, and installation of a 40-foot wide concrete spillway to meet 100-year flood requirements. Design deliverables at 5%, 65%, 95%, and 100% were completed. Design of the new dam was accelerated allowing completion in four months. This allowed construction to begin 45 days early and completion nearly two months ahead of schedule. Construction began with erosion control measures including installation of 1,000 lineal feet of silt fencing. Six-inch, 30,000 gph diesel pumps were deployed to pump the lake level down, maintain the low water level during construction, react to rain events, and ensure workers and the RCC product were not threatened by rising water during construction. The old dam was left in place. Excavators were used to expose the front face of the dam, which was thoroughly cleaned with a high pressure washer so that the new RCC dam would achieve a good bond to the existing dam. Clearing and grubbing was completed on 2.5 acres along the spillway on both sides of the channel.

EMR was awarded a contract for debris segregation in response to an EF 5 tornado that hit Joplin, Missouri on May 22, 2011, one of the country's deadliest tornadoes in over 60 years. Responding immediately was critical and EMR had personnel on-site to assess the task and begin writing project plans within two hours of the task order award. Within 18 hours EMR had 15 staff mobilized and with 36 hours, 47 staff, including a project manager, safety supervisor, industrial hygienist, safety and environmental technicians, and equipment operators, making up five segregation crews, as well as project support personnel. Upon arrival, EMR immediately met with U.S. Army Corps of Engineers personnel, assessed the area, set up a mobile command center and office, performed Accident Hazard Analysis, and began on the project-specific Health and Safety Plan. EMR's first tasks were to respond to a body recovery and to assist the Fire Chief with flaggers and equipment operators to begin moving and separating debris. Complying with Emergency Management Debris Removal Guidelines, EMR removed debris from roadways with trackhoes and backhoes, while dozers assisted with sorting and piling of debris in the required six categories of electronics, large appliances, hazardous waste, vegetative debris, construction debris, and household garbage out of foot and road traffic allowing for emergency and utility crews the ability to respond timely.

EMR conducted an oyster survey and depth of cover survey for the planned removal of an abandoned 12-inch diameter, 0.58-mile long natural gas pipeline in San Antonio Bay, Texas. EMR subsequently conducted agency consultations with U.S. Army Corps of Engineers, National Oceanic and Atmospheric Administration – National Marine Fisheries Service, U.S. Forest and Wildlife Service, Texas Parks & Wildlife Department, Texas General Land Office, and State Historic and Preservation Office. The project involved negotiating construction best management practices with federal and state resource agencies for work within designated essential fish habitat

EMR performed a Site Investigation, Remedial Investigation with Human Health Risk Assessment and Ecological Risk Assessment, and Feasibility Study at a Formerly Used Defense Site (FUDS). Four Areas of Concern (AOCs) were delineated: a former JP-4 UST, an aircraft wash rack, a JP-4 fuel transfer facility, and a solvent-impacted hangar facility. The sampling plan was designed to efficiently delineate all AOCs while reducing groundwater monitoring well and redundancy. 165 soil, 190 groundwater, and 13 soil vapor soil samples were collected during two different seasons and performed spatial analysis in GIS to delineate the contaminant plume. EMR worked to isolate FUDS impacts within multiple medias, and collected baseline data to help refine contaminants that could be attributed to other sources. The majority of borings and wells were completed in aircraft traffic areas that required detailed construction and restoration. It was determined that human health risks from potential exposure to site contaminants at the four AOCs were in excess of levels established by the Minnesota Pollution Control Agency under the no action alternative. Through the completion of the ERA, EMR established that the sites in question were not a threat to off-site ecosystems, but adjacent contaminated sites may be a significant threat to nearby natural resources and endangered species. To conclude the investigation, EMR offered a wide range of remediation options to the U.S. Army Corps of Engineers, including excavation, capping, soil/groundwater treatment, in-situ chemical remediation, and phyto-remediation.

EMR constructed a 10,872 square foot ammunition surveillance and inspection facility at the Redstone Arsenal for surveillance and inspection operations associated with small arms munitions for the Army. EMR complied with a strict 12 month schedule for the completion of the entire project, which included demolition of the existing facility, construction of utility infrastructure, construction of roads and parking lots, construction of the new ammunition surveillance facility, and the integration with the existing ammunitions storage bunker. The new facility consisted of a steel frame with cast-in-place blast walls strategically placed in order to partition various areas for munitions inspection operations. Specifications required that the new facility be integrated with the existing ammunition storage bunker so that munitions could be transported to the building easily and under appropriate security. The facility included high bay rollup doors, inspection bays, cast-in-place concrete storage cubicles, locker rooms with showers and restrooms, break room, mechanical/electrical space, electrical service, water, sewer, gas, concrete and asphalt paving, storm drainage, information and communication systems, security, and site improvements. As part of the overall facility plan, EMR installed approximately one mile of new electrical, water, sewer, and gas utility systems to service the new facility. The project also included clearing and grubbing of 6-acre site, including stripping of the top six inches of soil prior to construction. Construction included paving requirements to widen and improving an existing one-half mile access road and shoulders, and the construction of a new parking lot for government and civilian vehicles.

The Energy Conservation Improvement Program (ECIP) Electric Peak Demand project was undertaken by the Redstone Arsenal in an effort to save operating expenses associated with electrical power demand and energy charges from the local utility company. EMR performed design and construction activities to convert an existing emergency generator system into a peak demand reduction system with the objective of reducing electrical power demand by 326 kWh per month. The project was performed in three phases: 1) verify the existing design; 2) perform electrical construction work to implement system conversion; and 3) test and commission the converted system, and reconfigure for optimum effectiveness. The existing emergency power system consisted of six natural gas-powered generators located in the Sparkman Center Plant. In addition to the peak demand generator conversion, EMR reconfigured the Joint Alternate Command Element base communications system and installed a second pad-mounted transformer with associated feeders. The system is currently performing as designed.

NAVFAC Midwest contracted EMR to design and build an improved 400Hz electrical distribution system for Aircraft Ground Power Units (AGPU) for the 16 E-6B Mercury aircraft, serving U.S. Navy's TACAMO (Take Charge and Move Out) Air Wing at Tinker Air Force Base. The existing AGPU had never met the needs of the E-6B aircraft. The relevant data pertaining to the existing AGPU was compiled, and EMR designed a new state-of-the-art, solid state point-of-use frequency converters to provide 400Hz power to the Navy's E-6B aircraft. EMR proffered a design guarantee of an operational system, and the design was approved by NAVFAC. The project was performed in two phases: (1) design/build of four 180 kVA 400Hz AGPUs in the four bays of Building 820 (Hangar) at a cost of $1.47 million; and (2) design/build of six 180 kVA 400Hz AGPUs on the flight line at a cost of $1.88 million. During commissioning of the first phase installation, the AGPUs provided power to perform tests on the aircraft that had never been done before with a solid state frequency converter. AGPUs installed during Phase 1 have been in service since May of 2008 and have performed without incident. The ten 400-hertz AGPUs replaced nine diesel powered Trilectron AGPUs, which has resulted in an annual savings of over 650,000 gallons of diesel fuel ($1.4 million) per year plus an additional $25,000 in maintenance costs.

EMR provided construction and mechanical upgrades of System Building 499 at the Red River Army Depot as a subcontractor to TolTest under their AFCEE WERC ID/IQ contract. DLA warehouse/office Building 499 was occupied and fully operational, serving as the shipping and receiving center supporting worldwide warfighting efforts. Design recommendation and facility design was implemented to modify the HVAC system, install a reflective roof coating and replace lights with more efficient, reduced-heat light fixtures. EMR provided upgrades of the HVAC air cooling system, including placement of new equipment, modification of the ductwork, and installation of equipment controls for a 680,000 square foot warehouse, shipping, receiving, and office complex. New fire alarms were added to the existing system. EMR also provided a new roof coating by applying a reflective white coating to the existing EPDM roof system. Installation of the reflective coating required preparation of the existing EPDM surface that had been in place for 10 years. The reflective coating installed was a water-based liquid applied Elastomeric/Acrylic coatings EPA ENERGYSTAR rated coating with an Initial Solar Reflectance and Thermal Emittance of 88% reflective quality. Training was provided to over 25 DLA employees on the operation of the new computer controlled HVAC system.
