AREA A/B ENGINEERING REPORT - Waste Management

Geosyntec Consultants
The LCRS is installed along with the liner system, before any placement of waste. Although the
design of the landfill’s gas management system is planned before construction of the landfill
begins, it is installed after a sufficient volume of waste has been disposed that can optimally
support the GMS. Pumps, piping, and electronics used for the LCRS and GMS are designed to
manage the projected volume of liquids and gas to be collected, conveyed, stored, and
transported. The LCRS and GMS equipment and appurtenances must be appropriate for their
intended use, with confirmation from the manufacturer that the specifications on proper operation,
use, and maintenance of the equipment have been respected. An independent third party CQA
program is required to certify that all LCRS and GMS components are installed in accordance
with design specifications and regulatory requirements.
2.2.4 Operation and Maintenance
After construction but prior to commencing operations, the landfill operator must
obtain an operating permit. This permit prescribes the operating and
maintenance criteria and procedures for the operating life of the landfill. The
operating permit must be adhered to and includes various details including
operating hours, waste inspection requirements, procedures to enforce
restrictions on receipt of non-MSW (i.e., hazardous or radioactive waste, regulated
medical waste, state-designated “special” wastes, bulk liquid wastes), designation of specific
operating equipment, staff responsibilities, daily operational requirements, inclement weather
operation, and litter and nuisance control. Procedures for control of potential emissions to air,
water and groundwater must be detailed. All State programs regulating MSW landfills must
include these baseline protections, and State agencies are free to add restrictions necessary to
address local conditions.
2.2.5 Environmental and Performance Monitoring and Reporting
Monitoring must be planned and executed to verify protection of environmental media.
Performance monitoring for the landfill includes:
• LCRS monitoring (e.g., recording of leachate flow rates, head on the liner,
etc.);
• Monitoring leachate quality at the LCRS sumps and/or storage tanks;
and
• GMS monitoring to comply with the requirements of the Clean Air Act (e.g., wellhead
monitoring, surface emissions monitoring of the cover), as well as to address RCRA
obligations controlling the explosive potential of methane.
Landfills must demonstrate that leachate accumulation is minimized by maintaining a maximum
one-foot head (i.e., height of liquid level) above the liner system. This restriction prevents
