Monitoring Records Sludge analyses are submitted to MDE from treatment plants, a recent sludge analysis is required for each permit application, and records from applicators, site inspections, and treatment plants are reviewed. Site Inspection Site inspections are held during permit review by MDE and County Health staff, during the sludge operation, and after completion. MDE conducts about 1,500 sludge site inspections each year. We all do. Sewage customers get an economical disposal plan.
