Client: Naval Amphibious Base Little Creek, Norfolk, Virginia - Operations and Maintenance Manuals, Naval Amphibious Base Little Creek, Norfolk, Virginia
Develop Operations and Maintenance manuals for 29 sanitary lift stations at the Naval Amphibious Base (NAB) Little Creek.
As one of the delivery orders under an Indefinite Quantity Contract (N62470-92-D-6450) with Navy Public Works Center, SCS developed Operations and Maintenance manuals for 29 sanitary lift stations at the Naval Amphibious Base (NAB) Little Creek, Norfolk, Virginia. The project included the performance of field investigations and the preparation of manuals in accordance with Commonwealth of Virginia State Department of Health requirements.
An extensive sewerage collection and conveyance system covered the Base, with a flow through of approximately 1.2 mission gallons per day. The collection and conveyance system consisted of 29 lift stations, several miles of force mains and gravity lines, manholes, oil/water separators and grease pipes. There were five main stations into which the other 24 stations discharged. The five stations were permitted to discharge to the Hampton Roads Sanitation District force mains which lead to the Chesapeake/Elizabeth Wastewater Treatment Plant.
The general manual was comprised of information pertinent to the entire system such as: State Discharge Requirements; Description and Operation of the Sewerage System; Personnel Responsibilities; Laboratory Testing; Sewerage System Records and Reports; Maintenance; Emergency Operation and Response Program; Safety; Utilities; HRSD Permit; Industrial Wastewater Discharge Regulations; General Development Map & Lift Station Figures; Standard Operating Procedure for Inspection of Sewage Lift Stations; Repair Maintenance Work Request; Preventive Maintenance Work Orders; Daily Check Log; Self Monitoring Sampling Report; Training Log; Additions to Sewage Pump Station Alarm System Drawing; and After Hours Call Back List.
The 29 lift stations had separate manuals containing station-specific information including:
Modification Record Sheet.
Operation and Maintenance Procedures.
Lift Station Description.
Records and General Maintenance Requirements.
Client: Nuclear Fuel Assembly Plant; Lynchburg, Virginia
Multi-task Environmental Services for a Nuclear Fuel Assembly Plant and Research Center. Assignments included Environmental Compliance and Evaluation, RCRA Lagoon Closure, Groundwater Assessment, and Permitting Assistance.
Schedule: 1988 - 1991
Scope of Work:
SCS was retained to provide environmental services under a task order contract at a nuclear fuel assembly plant and nuclear research facility in Lynchburg, Virginia. The first assignment was preparation of an Environmental Evaluation report, as required by the Nuclear Regulatory Commission's license renewal process. The self-evaluation report included detailed descriptions of facility operations with respect to their impact on the surrounding environment and compliance with existing permits and regulations. Topic areas included water supply, wastewater generation and treatment, solid and hazardous waste management, and air pollution control. The report also included detailed environmental monitoring programs, and evaluation of historical monitoring data generated under the programs. A final component of the report was a description and evaluation of the facility's management approach, organization, and staffing needs with respect to environmental matters.
Subsequently, SCS provided specific recommendations for improvements to the domestic wastewater treatment plant, air emission scrubbers, industrial wastewater treatment plant, and solid waste incinerator.
Other services included preparation of plans and regulatory negotiations involving closure of two RCRA surface impoundments, one containing hazardous waste and one containing "mixed" (radioactive and hazardous) waste. In preparation of the plan, SCS designed a treatment system to permit pond water to be used in a non-cooling system located elsewhere in the facility.
Other projects included groundwater monitoring and evaluation, an environmental assessment for a property transfer, and a groundwater and soil assessment to evaluate and characterize the extent of trichlorethylene contamination.
Client: Southeastern Public Service Authority (SPSA), Chesapeake, Virginia - Small Quantity Generator Hazardous Waste Management Feasibility Study
SCS surveyed and analyzed 22 small quantity hazardous waste generators and recommended appropriate actions to improve management of hazardous wastes for six cities and two counties in southeastern Virginia.
SCS was retained by SPSA to conduct a survey of the small quantity hazardous waste generator (SQG) population in its area and determine the amounts and types of hazardous wastes generated, as well as the current disposal methods practiced. The study area covered the Cities of Chesapeake, Franklin, Norfolk, Portsmouth, Suffolk, and Virginia Beach, and the Counties of Isle of Wight and Southampton. Twenty-two industrial groups were identified, based on the types of waste expected to be produced and on the types of goods and services provided.
SCS chose a two-tier approach to the survey. First, the number of SQGs and the types and amounts of waste generated were estimated using the California Technical Manual "No Survey" method. Second, a limited survey was conducted, using a stratified random-sampling method, to determine if the SPSA service area SQG data differed significantly from the national data; the survey also provided information on SQG waste management practices in SPSA's service area.
The results of the survey indicated that approximately 86.8% of the wastes were solvents and paint wastes. The survey indicated that the majority of SQGs disposed of their wastes properly; only seven percent of the respondents reported using an inappropriate disposal method (e.g., sending wastes to a sanitary landfill or transfer station).
In order to project future SQG waste generation rates, SCS calculated the projected economic growth and the population growth. The results suggested that SPSA can anticipate 67% more hazardous waste will be generated in the year 2010. To assist SPSA in determining methods which would help meet the future needs of the SQG population, SCS analyzed several alternatives, including no additional action. Recommendations included: an educational outreach program; upgrade of security against receipt of hazardous wastes at the landfill(s), transfer station(s) and on haul trucks; recycling; and requirements that SQGs using SPSA services provide proof of a reasonable amount of liability insurance. The final recommendation was that SPSA should not implement a plan to provide a hazardous waste collection/transfer facility, as this could cause SPSA to become a hazardous waste generator itself.
Client: U.S. Department of the Navy, Naval Surface Warfare Center, Dahlgren, Virginia - Implementation of SPCC Plan at the Naval Surface Warfare Center, Dahlgren, Virginia
To prepare Spill Prevention, Control and Countermeasure (SPCC) plan improvements for the Naval Surface Warfare Center (NSWC).
Under an indefinite quantity contract, SCS was asked to prepare SPCC improvements for 235 sites throughout the NSWC in Dahlgren. SPCC improvements were designed for drum storage areas, small above-ground heating fuel tanks and above-ground waste oil tanks.
Specifically, SCS provided designs for a protective vault and whistle vent alarms at 228 existing tanks; level indicators at two sites; high level alarms at four sites; containment dikes and high level alarms at eleven sites; containment dikes at six sites; contained parking at two sites; and a high level alarm, containment dike, and truck unloading facility at two sites.
The project also included the addition of a high-density polyethylene liner for a 1,200,000 gallon above-ground No. 2 heating fuel oil storage tank and a 42,000 gallon above-ground No. 2 heating fuel tank servicing the facility's power plant. Other services provided included new vent piping, whistle vent alarms, and spill containment fill manholes to over 150 family housing units basewide.
