POL Impacted Soil Remediation via Landfarming

Holloman AFB

Holloman AFB
Client: USACE, Omaha District
Contract value: $21.5M (100% Complete)
Description: Multi-faceted environmental restoration and compliance program

 

Scope of Work: Bhate evaluated the operation and maintenance of four failing soil vapor extraction systems (installed by others) associated with the remediation of hydrocarbon contaminated soils. After initially using a commercial off-site disposal facility, Bhate was able to permit, engineer, build and operate two land farms on the base. Also, with the award of Mod 2, Bhate was tasked to execute the West POL Remedial Action and the SWMU 183 Triad Approach RCRA RFI to identify and delineate releases of hazardous compounds from Holloman’s 22 mies of mixed industrial/sanitary sewer lines. Bhate prepared plans for the characterization and removal of petroleum contaminated soil (PCS) adjacent to four 50,000 gallon JP-8 tanks.




U.S. Army Europe Fuel Facilities

Location: Germany, Belgium, Italy, and The Netherlands
Client: U.S. Army Engineering & Support Center, Huntsville (USAESCH)
Description: Bhate developed Operational Maintenance Support Information (OMSI) Manuals for 57 fuel facilities in Germany, Belgium, Italy, and the Netherlands to provide a comprehensive, organized library of as-built materials, equipment, and systems to be used as the first step in solving operational, maintenance, repair, or spill response problems.

 

Scope of work: We developed manuals by conducting site visits to obtain site-specific facility equipment inventories, procedures, and personnel responsibilities for each of the 57 facilities in eight weeks. The fuel facilities included:

  • Class III facilities (including rail and truck loading and off-loading, transfers from pipeline and between tanks)
  • POL Points (including truck loading and off-loading)
  • Transportation motor pools (TMPs) (primarily mogas and diesel dispensing facilities)

The OMSI manuals included:

  • General and historical site information
  • Personnel and organizational responsibilities
  • Safety guidelines and MSDSs
  • Equipment inventories (including tanks, dispensers/fill stands, oil/water separators)
  • Normal operational procedures (including use of the ATG/leak detection systems, Fuel Master systems, corrosion protection systems) including flow diagrams
  • Spill response procedures to address pollution prevention (P2) concerns and equipment use (including diagrams showing emergency response equipment and probable flow pathways)

The OMSI manuals for the Class III facilities also included detailed valve tagging and/or inventorying; detailed flow diagrams and inventories for all normal operational pumps, filters, tanks, and valves; and valve alignment charts for normal operations. Bhate also developed a Petroleum Quarterly Maintenance Statement of Work (MSOW) to engage a contractor to perform periodic required maintenance and minor repairs for 31 European facilities located in the Netherlands, Italy, Belgium, and Germany. The MSOW includes a detailed cost estimate (per site and total cost per each Area Support Group) and recommendations to the size/number of maintenance teams.

Multi-Site Remedial Action

Site 1

Location: Moody AFB, GA
Client: USACE, Omaha District
Contract Value: $2.94M
Description: The project described below was a Firm Fixed Price TOs in which Bhate performed multi-site (Burma Road Landfill LF-01, Industrial Area SS-24, South Gate Fill Site LF-42 and the Vehicle Maintenance Area SS-31) remedial activities of PCE, TCE, DCE, VC, CT, chloroform and benzene plumes covering approximately 47 acres and comprising a significant portion of the SOW proposed for the Louisville ERS. Bhate performed Corrective Action for Burma Road Landfill (LF-01) and the Vehicle Maintenance Area (SS-31).

 

Scope of Work:
The selected corrective action alternative for SS-31 was Monitored Natural Attenuation (MNA) for a 4-acre chlorinated solvent GW plume with individual contaminant concentrations slightly above MCLs. At LF-01, we investigated, designed, constructed, installed, and operated a remedial system to address the contaminated GW plume emanating from the Burma Road Landfill without compromising the landfill cover or damaging the nearby wetlands. To achieve project goals, we partnered with the Georgia Environmental Protection Division (GA EPD), MAFB, and the Omaha District to jointly investigate and remediate the GW contamination present at LF-01. The benzene plume at LF-01 extended beyond the Base perimeter and impacted privately held lands; therefore, regulatory support and community concurrence was paramount in achieving the project goals. Bhate’s remedial investigation of the complex hydrogeologic conditions at LF-01 and the off-base impact required pilot testing of innovative technologies to support the remedial design phase and development of the Corrective Action Plan (CAP). A field investigation using Membrane Interface Probe (MIP) technology identified the “hot spot” location and indicated a possible soil-GW interface zone of contamination, in which contamination fluctuates with the rise and fall of GW. To determine the viability of the microbial aerobic biomass, the community structure, and physiological status of the microorganisms at LF-01, Bhate conducted a phospholipid fatty acids (PLFA) analysis. Under the direction of Dr. Stapleton, PE, BZ designed, constructed, and implemented the system to inject nutrients and air through a series of 25 optimally placed injection wells distributed among five treatment zones which compensated for future GW plume migration. Bhate developed and submitted a CAP, Corrective Action Design, and O&M Plan for the selected remedial alternative to the GA EPD. LF-01 is the “showcase site” for MAFB and has been used as an educational facility for local area high schools interested in careers in environmental microbiology. On September 27, 2007, LF-01 received recognition and distinction as being the first of the Active Remedial Systems at MAFB to be decommissioned with regulatory concurrence and was subsequently nominated for the prestigious USACE Chief of Engineers Design and Environmental Award for 2008.


Alabama Storm Debris Cleanup

Site 1

Location: Various Counties in Alabama
Description: The April 25-28, 2011 tornado outbreak was the largest and one of the deadliest tornado outbreaks ever recorded, affecting the Southern, Midwestern, and Northeastern United States. 358 tornadoes struck 21 states causing 324 deaths. The deadliest day was April 27th with 211 recorded tornados in a 24-hr period. The State of Alabama suffered 238 tornado-related deaths.

 

Scope of Work:

The widespread devastation required a massive cleanup effort for central and northern Alabama. Bhate was contacted for support and immediately dispatched debris segregation teams to hard-hit sections of the state. From Montgomery, AL to the Tennessee line, Bhate managed the segregation of massive piles of storm debris. Field teams included a project area manager, a site safety manager, and segregation personnel consisting of supervisors, equipment operators, asbestos technicians, and laborers. By May 11th, Bhate was providing management personnel and 20 segregation teams dispatched to eight locations across Alabama. At project peak, Bhate was fielding over 160 personnel. Crews worked along highways and in neighborhoods where storm debris was piled. Household hazardous waste was separated from housing debris and limb waste. Suspect asbestos-containing materials, electrical waste (e-waste), and appliances (white goods) were also separated for disposal. Transport crews packaged and disposed of hazardous debris to an approved landfill. Bhate crews were onsite until early August 2011.


Supplemental Investigation at Formerly Used Defense Sites

Site 1

Location: Francis E. Warren Air Force Base – Cheyenne, WY
Description: Bhate competitively won this $1.48M performance-based, firm-fixed price contract to fill previously existing data gaps at three Former Atlas “D” Intercontinental Ballistic Missile (ICBM) Sites at F.E. Warren Air Force Base in Cheyenne, WY. The primary project objective was to provide further delineation of soil and groundwater impacts for the purpose of moving each site closer to Site Closure (SC) status.

 

Scope of Work:

When the missile sites were operational, ICBMs were regularly fueled as part of readiness exercises. After each exercise, fuel tanks and lines were flushed with trichloroethene (TCE) to remove any residual fuel that could pose an explosion risk. Consequently, waste TCE and residual fuel were discharged into flame pits adjacent to Launch and Service Buildings. The residual liquids subsequently infiltrated into a highly beneficial groundwater aquifer. Atlas Site #4 possessed a TCE groundwater plume over 10 miles long, occurring in complex geological formations at depths greater than 300 feet. This condition required the City of Cheyenne to treat the municipal drinking water supply. To meet project objectives, Bhate provided drilling, geophysical, hydrophysical, surveying, and site reclamation services. Over 5,100 feet of large bore Roto-Sonic drilling was performed in the geologically formidable Ogallala Formation and underlying White River Formation to aid delineation efforts. Bhate determined discrete flow zones in the formations, and then nested multiple completion wells to better define chemical components and vertical flow characteristics. Results of Bhate’s efforts reduced the Atlas Site #4 TCE plume boundary delineation both in the source area and distal end of plume.


Source Area Characterization of Operable Unit #1

Site 1

Location: Maxwell Air Force Base – Montgomery, AL
Description: Bhate performed a Source Area Characterization of Operable Unit Number 1 (OU-1) at Maxwell Air Force Base in Montgomery, Alabama. Project tasks included site characterization under which we prepared a Quality Assurance Project Plan (QAPP); a Work Plan, and a Safety Plan. Additional activities included soil and groundwater sampling, potential receptor identification, and analysis of risk to human health and the environment.

 

Scope of Work:

Bhate held quarterly meetings with regulators, including ADEM, to discuss progress, results, and potential solutions. Bhate used direct push technology (DPT) featuring membrane interface probes (MIPs) for soil analysis. Bhate advanced 165 soil borings and collected 330 discrete groundwater samples from two different groundwater horizons using innovative mini-sonic drilling techniques. Bhate used a Geointegration approach to install 12 permanent monitoring wells around the perimeter of the contaminated area, on and off-Base, to delineate the extent of contamination and optimize the groundwater monitoring well network. Bhate performed aquifer pump tests in newly installed monitoring wells and collected groundwater samples to monitor the migration of the plume, fill in any OU-1 data gaps, and ultimately calculate the cleanup time for the existing on-Base plumes. Bhate determined the locations of five source areas and identified a 1.75 mile long chlorinated solvent plume that was previously undiscovered. Bhate has communicated the results of the investigation with Maxwell AFB, AFCEE, USACE, ADEM, Montgomery Water Board, and Tier 1 and 2 Partnering Teams. Bhate is supporting community relation programs such as the Restoration Advisory Board.


Emergency Response to Gasoline Spill

Site 1

Location: Hoover, AL
Description: Five days before Christmas 2012, Alabama’s Hoover Fire Department was notified of gasoline vapors in the storm sewer at a local gas station. A report was forwarded to the Alabama Department of Environmental Management (ADEM). Per ADEM’s request, Bhate immediately mobilized to begin response activities. Initial field reconnaissance and observations confirmed that the suspected release was associated with the Hoover gas station.

 

Scope of Work:

Bhate began monitoring vapor levels in the storm sewer and installed a vapor recovery from the sewer system. Bhate coordinated fuel removal from the tanks at the gas station. Six recovery wells were installed at the site to recover free product from the groundwater surface. Vapor recovery was initiated using large industrial-type fans over the storm drain in the parking lot of a nearby shopping center. The fans created a negative pressure on the storm drain system and greatly reduced vapor emissions. Vapor concentrations in the storm sewer and sanitary sewer did not exceed 10% of the Lower Explosive Limit (LEL) but reached Photo Ionization Detector (PID) levels of over 4,000 ppm. The combined efforts of product and vapor recovery greatly reduced vapor concentrations in the sewer. Approximately 200 gallons of gasoline and 1,505 gallons of fuel/water mix were recovered.


FEMA Petroleum Tank Removal

Site 1

Location: Various U.S. Locations
Description: Bhate was selected by FEMA to assist its mission for the Storage Tank Management Program (STMP). Bhate was tasked with conducting regulatory reviews and documenting former storage tanks for U.S. Environmental Protection Agency (USEPA) submission.

 

Scope of Work:

Bhate conducted removal/closure of non-operational Underground Storage Tanks (USTs) and Aboveground Storage Tanks (ASTs), as well as repairs/upgrades of operational USTs/ASTs at various locations in the U.S. and its territories. Bhate reviewed 366 former FEMA tank systems and conducted detailed desktop reviews using the FEMA UST database, interviews, publicly-available databases, and state databases to determine compliance and regulatory status. Bhate prepared supporting documentation including tank evaluation reports and recommendations. Due to FEMA’s aggressive schedule; the nature, complexity, and size of FEMA’s program; Bhate’s coordination skills were critical to maintaining and completing the project within the 24-month period of performance. Bhate coordinated with multiple stakeholder groups including radio stations, former owners, FEMA facility contacts, the EPA, as well as other state and local regulatory agencies including local fire departments.


SS08 Remediation

Site 1

Location: Maxwell Air Force Base – Montgomery, AL
Description: Maxwell Air Force Base in Montgomery, Alabama has a large chlorinated solvent plume that expands over three miles north to south and is approximately ½-mile wide. An engineered remedial action involving the injection of zero-valent iron (ZVI), emulsified vegetable oil (EVO), sodium bicarbonate, and calcium carbonate was conducted to eliminate or reduce the amount of off-Base contamination reaching Maxwell AFB by treating a hot-spot at SS-008.

 

Scope of Work:

Work associated included remediation of groundwater contamination, which is a portion of the 3 mile long, ½ mile wide, plume (OU1). Bhate conducted multi-horizon subsurface investigations, pilot testing, remedial design, remedial action, remedial action operation, remedial process and optimization, performance monitoring, and reporting. Bhate used in-situ enhanced bioremediation (ISEB) and micro-scale zero-valent iron (ZVI) to treat groundwater. The highest trichloroethene (TCE) concentration (4,090 ppb) in groundwater was detected in the
intermediate groundwater zone. Bhate injected 152,000 lbs of micro-scale ZVI and 125,000 lbs of SRS-Z to support the growth of the anaerobic microbial population. Total amendmentvolume included 750,000 gallons into 3 contamination zones via 150 injection points using Direct Push Technology (DPT) to depths up to 75 feet below ground surface (bgs). 150 groundwater samples were collected at depth intervals. Monitoring wells were also installed and sampled. Performance monitoring was used to confirm the effectiveness of the remedial action.


In-Situ Remediation of Pesticides in Sediments Using Sodium Persulfate

Site 1

Location: Gunter Annex, Maxwell Air Force Base – Montgomery, AL
Description: The Gunter Annex surface drainage system is designated as site SD-001 under the Installation Restoration Program (IRP) and is located immediately adjacent to Gunter Annex. The property is currently owned by the Alabama Department of Corrections (ADOC). Drainage associated with Gunter SD-001 initiates from within the boundaries of Gunter Annex and flows from three pipes located just east of the site into an ecologically sensitive, area known as Three Mile Branch Creek.

 

Scope of Work:

It is believed that pesticide runoff in surface water from Gunter Annex contributed to the drainage ditch impacts. Chlordane was detected in sediment samples, from within the ditch, at concentrations up to 13 times the ecological screening levels. As a precaution, Bhate retrofitted the unlined ditch with an HDPE pipe to eliminate future surface water contact with sediments. Additionally, in lieu of very costly excavation and disposal of chlordane-contaminated sediments, Bhate developed an innovative in-situ remedial approach using sodium persulfate to oxidize the contaminants. Our approach resulted in a cost avoidance of $1.2M for the Air Force – without impact to the installation mission or the ecologically sensitive areas adjacent to SD-001.


PCB Remedial Action Investigation

Site 1

Location: Stennis Space Center, MS
Description: Bhate performed a Remedial Investigation (RI) associated with polychlorinated biphenyls (PCBs) and volatile organic compounds (VOCs) contamination in soils and groundwater. As a result of the RI, Bhate developed a corrective action plan (CAP) for remediation activities. Bhate provided quality control/project oversight for NASA during cleanup activities which included the excavation, removal, and incineration of 471 tons of PCB-contaminated soils.

 

Scope of Work:

Bhate collected 108 soil samples and 12 groundwater samples from 40 soil borings for PCBs and VOCs analysis. Saturated PCB soils were encountered during concrete removal for a foundation system at Building 3216, when two 2-inch diameter electrical conduit lines were encountered by construction crews. Following discovery, soil samples were collected for PCB analysis. Results indicated that PCB levels were in the range 23,000 milligrams per kilogram (mg/kg) or 2.3% to 42,000 mg/kg or 4.2%. Construction activities were immediately halted by NASA until further investigation was completed. Bhate developed an approach to expedite site characterization for subsequent remediation in accordance with Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and Toxic Substances Control Act (TSCA) regulations. Due to the compressed schedule and time-critical nature of the project, Bhate worked closely with Stennis, Mississippi Department of Environmental Quality (MDEQ) and the U.S. Environmental Protection Agency (USEPA) Region 4 for early input and buy-in on the
investigation strategy.
