Polk County North Central Landfill Bioreactor

Jones Edmunds designed and obtained permitting for modifications to the Leachate Management System at the North Central Landfill, including the design of the landfill’s bioreactor system. Jones Edmunds teamed with the University of Florida to design and permit a bioreactor. This will help the County save over $1 million a year on leachate treatment and disposal costs. The County transported all of the leachate from its three facilities to Jacksonville, Lakeland, or Miami for treatment. The goal of the bioreactor is 100% leachate recirculation of the leachate from all three facilities with the only cost of leachate hauling/treatment to be the cost of hauling the leachate from the Southeast or Northeast Landfills to the North Central Landfill. Since operation began, approximately 19 million gallons of leachate have been recirculated. The project specifically includes designing the bioreactor system of pumps, force mains, recirculation hydrants, and headers and a Supervisory Control And Data Acquisition (SCADA) system for operating and retrieving data from the system. Not only does the SCADA system allow the County staff to see how the pumping and delivery systems are functioning from the office, but it also allows the operator to change the pumping regime from the office and produces the FDEP-required reports. Jones Edmunds provided the following bidding and construction-phase services on the project:
  • Resident observation
  • Shop drawing review
  • Pay request review
  • Processing of change orders
  • Processing of requests for additional information
  • Conducting construction meetings
  • Reviewing submittals
  • Preparing FDEP-required monthly progress reports
  • Certifying construction-completion reports
  • Providing startup and training services after construction

Polk County North Central Landfill Phase V Design, Permitting, and Construction Services

This 30-acre landfill expansion consisted of a 27-acre double composite liner system and a 3- acre singled-lined vertical expansion over portions of the existing on-site Class III landfill. The design included a number of innovative elements to increase current and future capacity. This design also helped reduce the construction and operational costs of the facility. We constructed portions of the Phase V bottom liner below the seasonal high water level, resulting in a significant reduction in backfill material requirements and the generation of more than 200,000 cubic yards of soil for landfill operations. The design also included a unique leachate collection system liner flap and pump stations ready for future expansion to the east of the Phase V facility.

NASA Schwartz Road Landfill Closure

Jones Edmunds prepared construction drawings, specifications, and engineering reports necessary to close the 64-acre Schwartz Road Landfill. This landfill had operated since the late 1960s and received a combination of demolition debris and municipal solid waste from activities at Kennedy Space Center.

Wakulla County Lower Bridge Class III Closure Construction Phase

Jones Edmunds assisted Wakulla County with design, permitting, and performing construction phase services for the Lower Bridge Class III Landfill closure. The 5-acre Class III landfill closure design was developed to meet site-specific requirement and includes a clay barrier layer and protective cover. The work included excavation of waste located outside the permitted limits of the landfill and a large amount of re-grading and shaping of the landfill to lessen steep side slope. The design also included stormwater conveyance and gas vents. The design was developed to minimize closure costs. Due to the relative remoteness of the site the materials of construction had to be carefully considered to make sure that they were locally available to avoid excessive costs. The clay barrier layer was selected in part so that local resources and contractors could be used to perform the work. A local contractor was awarded the project, which helps sustain the local economy. Construction-phase services included bid phase coordination, construction administration, resident observation, CQA of all liner materials, and FDEP CQA Report preparation.

Polk County Phase III Gas Collection System Operations

Jones Edmunds provided services required to operate and maintain Title V compliance for Polk County’s Phase III Landfill Gas Collection and Control System (GCCS) in 2012-2013. Additionally, Jones Edmunds provided training services to familiarize County personnel with the GCCS and assisted with the transition to County operation of the GCCS in 2013. Jones Edmunds operated, maintained, and repaired the Phase III blower/ flare station and wellfield during weekly site visits. Activities including standard maintenance activities such as modifying gas collection wells; lubricating gas collection blowers; and trouble-shooting pump, flow meter, and failsafe valve malfunctions. Personnel were available by phone on a 24-hour basis to provide County personnel with technical assistance in restarting the blower flare station during unexpected system shut downs. Additionally, personnel were available on site within four hours to perform emergency system evaluations and repairs if necessary. In addition to the day-to-day operation of the GCCS, Jones Edmunds performed Title V monitoring and reporting to maintain compliance with the site’s Title V operations permit. Jones Edmunds balanced the wellfield weekly and performed wellfield monitoring and surface emissions monitoring monthly. Additionally, Jones Edmunds performed visible emissions monitoring of the flare stack. Jones Edmunds documented all aspects of their work at the site and prepared a majority of the Title V reports for the site. The reports included NSPS/NESHAP Semi-Annual Report, Title V Annual Operating Report (AOR) and Statement of Compliance, Annual Title V Emission Form and Fee Calculation, Visible Emissions Testing, and Surface Emissions Monitoring.

Brevard County Central Disposal Facility Gas System Expansion & Modification

Jones Edmunds completed the design to modernize and expand the gas collection and control system (GCCS) at the Brevard County Central Disposal Facility. The GCCS required substantial upgrades to meet Title V requirements and to provide the estimated 3,000 scfm needed to supply the new 9.6-MW electrical power plant. The work consisted of evaluating the 140-acre system to determine the condition and areas requiring improvement. The GCCS analysis included reviewing wellfield data, gas quality, wellfield vacuum distribution, condensate management, and integration with filling operations. The new system included 2,200 linear feet of vertical wells, 11,000 linear feet of horizontal wells, and over 10,000 linear feet of HDPE pipe 16 inches and larger in diameter. Jones Edmunds also provided contract administration and construction services for the expansion and partial closure. A unique challenge was the need to keep the GCCS, which supplied approximately 2,000 scfm to the power plant, operating. Specifically, this required careful coordination with the County, the Contractor, the power plant, and Jones Edmunds field personnel.
