Project Overview
The City of Pontiac’s Collier Road Landfill was closed in 2006 following operation as a municipal solid waste disposal facility for over 20 years. Since that time, NTH has provided monitoring and maintenance services to ensure compliance with regulatory requirements and to protect public health and the environment working with limited resources to address on-going PA 451 requirements.
NTH provided investigation, design, and construction services for the City throughout the site closure and new landfill development process. Based on this involvement, NTH has an intimate understanding of the site history, hydrogeologic conditions, and landfill design, and we were uniquely qualified to provide long-term monitoring and maintenance services for the site including all environmental media (air, methane, groundwater, and surface water). We have developed a project team that incorporates NTH personnel who have extensive experience with the site, along with a sampling crew and analytical laboratory that are also familiar with the site monitoring system and requirements. We have also utilized selected subcontractors for drilling and earthwork services on an as-needed basis.
Project Scope
Our project team has provided post-closure monitoring and maintenance services for the Collier Road Landfill since 2006. In addition to implementing the routine groundwater, leachate, and methane monitoring programs, we have performed supplemental groundwater and methane investigations to address potential off-site migration issues. We have also represented the City of Pontiac during interactions with the Michigan Department of Environmental Quality (MDEQ) to address regulatory compliance requests and financial assurance inquiries.
Client Benefit
NTH was provided a proactive approach to site maintenance issues by planning and implementing preventive measures before problems arose and keeping the site in compliance with its Post-Closure Plan and environmental regulations.
