GZA was retained to complete third-party compliance monitoring pertaining to 401 Water Quality Certification conditions and use of Best Management Practices (BMPs) for a project involving nearly eight miles of new pipeline, as well as upgrades of related facilities.


On behalf of the New York State Department of Environmental Conservation (NYSDEC) and the Project Engineer, GZA conducted daily observations six days per week for a period of one year. GZA reviewed potential environmental concerns, including erosion and sedimentation control measures; wetland and stream crossings; and the potential presence of rare, threatened, and endangered species in the context of existing construction and permitting plans and permits as well as typical BMPs used during construction. GZA provided troubleshooting for issues arising in the field and facilitated on-site meetings with the regulatory agency and developer. Daily reports submitted to the regulatory agencies included weather conditions; location and type of work observed; status of required environmental controls; any observed compliance concerns; a brief discussion of resolution of any non-compliance issues; and pertinent site photographs.


With extensive experience in construction observation and consistent presence on site six days per week, GZA was able to respond quickly to any regulatory issues that arose, maintaining the client’s compliance with their permits and avoiding project delays.
