Compliance/Permitting
Geo-Logic Associates guides waste facilities through permitting, regulatory compliance, operational approvals, and closure requirements. Our team prepares technical documents, coordinates with agencies, and helps clients navigate complex environmental regulations throughout the facility lifecycle. Expertise includes:
- Plans: Preliminary and Final Closure and Post-Closure Maintenance Plans (PCPCMPs and FCPCMPs), Non-water Release Corrective Action Plans (NWRCAPs), Foreseeable Release Corrective Action Plans (CAPs), Stormwater Pollution Prevention Plans (SWPPPs)
- Reports: Disposal Site Information (RDSIs), Waste Discharge (ROWDs), Periodic Site Review (PSR)
- Solid Waste Facility Plan (SWFP) Applications
- Joint Technical Documents (JTDs)
- Conditional Use Permits (CUPs)
- Environmental Impact Reports (EIRs)/Environmental Impact Statements (EISs)
- Army Corps of Engineers 404 Permits
Compost Facility Services
Solutions to the unique and sometimes complex planning, operations, and construction issues facing composting facilities that our team has developed include low-permeability pads utilizing on-site materials, approaching stormwater design from a low impact development (LID) perspective, and stormwater designs that allow for 100% on-site containment of runoff and compost leachate.
Construction Support Services
Providing a complete range of on-site construction observation and testing services to ensure that each project is built to design specifications, GLA has provided construction management (CM) and construction quality assurance (CQA) services for more than 300 solid waste and liquid impoundment projects. Our field technicians are experienced with:
- Geomembrane non-destructive and destructive testing methodologies
- Field soils testing and evaluation of soils/synthetic interfaces
- Single- and double-ring infiltrometer permeability testing, documentation, and report generation
Cover Design
Our engineers design soil and geosynthetic final cover systems for all types of waste disposal facilities, with construction plans, specifications, and bid documents that are easily followed by the approving regulatory agencies and valued by contractors and construction managers for their constructability in a wide variety of climate zones and terrains. Our experience includes:
- Cover system studies and borrow source studies
- Geotechnical analyses for slope stability, settlement and liner systems
- Hydrogeologic studies
- Planting and irrigation systems, and long-term revegetation monitoring programs
- Construction quality assurance and construction management activities
Environmental Data Management
Geo-Logic Associates developed GLA-Data, a GIS-based database management system (DMS or DBMS) that streamlines environmental monitoring and reporting. The system helps clients manage monitoring data, evaluate trends, visualize results, and support regulatory reporting requirements. Users can:
- Access and view information related to specific landfills, wells, sample events, or analytical data
- View and analyze historical water quality data
- Generate and export custom graphs
- Run and export reports used for state agencies
- Manage any documents related to their landfills
Environmental Remediation
We help landfill, surface impoundment, and other regulated facilities evaluate and address environmental impacts associated with releases to soil, groundwater, and surface water. Our team develops practical remediation strategies, supports regulatory negotiations, and guides projects from investigation through implementation. We have experience with:
- Evaluation or Assessment Monitoring Programs (EMP or AMP) and Corrective Action Programs
- Engineering Feasibility Studies (EFS)
- Groundwater assessments and/or remediation work plans and regulatory negotiations for approval
- Evaluation of existing water quality monitoring systems
- Installation, development, and abandonment of monitoring wells and associated collection of air, soil, and water quality samples for laboratory analysis
- Evaluation and/or modeling of groundwater flow
Environmental Monitoring
Geo-Logic Associates has earned a reputation for technical excellence with both our clients and the regulatory community for our full-service environmental monitoring and reporting services, including groundwater, soil, soil-pore gas, soil-pore liquid, and surface water sampling, monitoring, and reporting program development and implementation as well as regulatory compliance.
Expansion Design
We design landfill expansions that support operational goals while meeting regulatory and environmental requirements. Our team develops construction documents, technical specifications, and bid packages that facilitate efficient permitting and construction.
Landfill Gas System Design, Monitoring, and Operations
Our landfill gas (LFG) specialists provide planning, design, compliance, monitoring, and operational support services for gas collection and control systems (GCCS). We help clients improve system performance, maintain regulatory compliance, assess site economic impacts, and evaluate beneficial use opportunities. Our expertise includes:
- Engineering services including: NSPS GCCS design plans, LFG phasing plans and system construction plans, LFG generation and collection modeling, LFG beneficial use feasibility studies, operation and maintenance of LFG wellfields, LFG operational assessments
- Compliance monitoring, such as surface emissions monitoring (SEM), perimeter probe, and leak detection
- LFG system services related to HDPE lateral and headers; air compressor and other pneumatic systems services, LFG blower/flares, wellheads, pumps, LFG system construction
Leachate Management
Geo-Logic Associates develops practical strategies for leachate collection, treatment, storage, transportation, and disposal. Our integrated engineering team helps clients reduce costs, improve system performance, and maintain regulatory compliance.
Solid Waste Planning Services
We help municipalities, agencies, and private organizations evaluate and implement sustainable waste management strategies. Our planning services support informed decision-making, long-term resource management, and operational efficiency.
Services include:
- Waste management planning
- Procurement support
- Waste characterization studies
- Financial and feasibility evaluations
- Siting and zoning analyses
- Stakeholder outreach and engagement
Stormwater Compliance/Design
GLA takes a tiered approach to treatment design that includes standard infrastructure design along with appropriate best management practices to meet increasingly restrictive stormwater discharge standards and increased monitoring and reporting requirements including navigating National Pollutant Discharge Elimination System (NPDES) compliance.
