A sludge contractor files an application for a permit with MDE which consists of soil and sludge tests and other information MDE uses to assure that all regulatory requirements are met. The site is also inspected to be sure that the application materials are correct. If everything is satisfactory, the contractor is permitted to apply the sludge. MDE inspects the farm during and after sludge application. To support the administration of the sludge program, sewage treatment plants are charged fees based on the amount of sludge they produce and how it is used.
County governments receive copies of every permit application.
County governments can review and comment on each application, request a public informational meeting, participate in site assessment visits, inspect and monitor each site in their county, and have the right to enforce the permit requirements. No cases of health effects or water pollution have occurred from the use of sludge on farms in Maryland. About 80,000 acres on more than 600 farms throughout Maryland are currently permitted to receive sewage sludge. The Maryland Department of the Environment has set up requirements to assure that use on land is safe for both humans and the environment. Pathogen Control Regulations require that sewage sludge be treated to reduce disease causing organisms to safe levels.
