Examples of Our Project Experience With Greenwood County
Class II and III Permitting & Design
In 2012, LaBella prepared a major permit modification to expand the Class II landfill. The vertical expansion encompassed an 18-acre footprint and added approximately 10 years of life to the facility
In 2017, LaBella prepared a minor permit modification application to remove the permitted benches on Cell 3 of the Class III landfill, which were designed by others, and gain additional capacity. To qualify for a minor permit modification and eliminate the need for a public meeting/approval process, the gained capacity was deducted from the unconstructed Cell 4. The SCDES agreed to allow the County to address the additional airspace in the upcoming major permit modification for Cells 4 through 8.
In 2022, LaBella rephased Cells 4 through 8 at the Class III landfill, which had previously been permitted by others. This work included both a minor and major permit modification. In addition, LaBella delineated wetlands and prepared wetlands permitting documents. LaBella completely redesigned Cells 4-8 to lower the base grade and maximize the disposal capacity of the facility. As part of the major permit modification, LaBella also rephased Cells 4-8 to minimize the construction area and maximize the disposal capacity of each future cell. This was achieved by reorienting future cells to increase the piggyback on existing Cell 3.
Class III Construction Phase Services
In 2006, LaBella prepared construction plans, specifications, and contract documents for the construction of Cell 3 (approximately 18 acres) and the partial closure of Cell 2 (approximately 10 acres) of the Class III landfill. We also performed construction oversight and prepared the construction quality assurance (CQA) documentation reports for the South Carolina Department of Environmental Services (SCDES) to confirm that Cells 2 and 3 were closed and constructed, respectively, in accordance with the plans and specifications of the permit documents.
In 2024, LaBella prepared construction plans, specifications, and contract documents for the construction of Cell 4 (approximately 12 acres) of the Class III landfill. In 2025, we performed construction administration and CQA services associated with Cell 4 construction.
Operational Services
In 2019, after a SCDES inspector noted a number of leachate seeps, we assisted the County staff in efforts to identify the source of the leachate
LaBella provided onsite guidance to County staff to excavate Cell 3 sumps and promote leachate drainage from the landfill sumps.
In 2020, we prepared a trap design that helped the County collect landfill gas from Cell 3 cleanouts, without oxygen intrusion, at a relatively low construction cost.
Engineering Services
Since 2006, LaBella has prepared capacity study reports and required annual SCDES reports for the Class II and Class III landfills.
We have also provided County environmental consultants with survey data and information required for the annual greenhouse gas reports and Title V air permit.
