Maryland Environment Section 9-947

      If the sewage or other waste that a manufacturing, commercial, or industrial plant or other building or premises discharges into a sewerage system is, because of its character, an unreasonable burden on the sewerage system, the authority that owns, operates, or maintains the sewerage system may:

            (1)      Impose an additional charge on the owner, tenant, or occupant of the plant, building, or premises; or

            (2)      Require the owner, tenant, or occupant of the plant, building, or premises, before it discharges its sewage or other waste, to treat the sewage or waste in a manner that the authority determines.
