The State of Michigan’s Department of Environment, Great Lakes, and Energy (EGLE) Hazardous Waste Program (HWP) conducts a Corrective Action Monitoring and Maintenance (CAMM) program that involves inspecting all RCRA Treatment, Storage, and Disposal (TSD) facilities that have completed corrective action. The CAMM program helps ensure facility compliance with the requirements of legal agreements in place. The presentation also discusses how Drone Photometry tools have assisted the CAMM program to the benefit of the Department and the facility.
