Treatment Works treating domestic sewage or any other sewage sludge or wastewater treatment device or system, used in the storage, treatment, recycling, and reclamation of municipal
or domestic sewage, including lands dedicated to the disposal of sewage sludge that are located within the confines of the facility, with a design flow of 1.0 million gallons per day
(MGD) or more, or required to have an approved pretreatment program under 40 CFR Part 403.
Not included are farm lands, domestic gardens, or lands used for sludge management where sludge is beneficially reused and which are not physically located in the confines of the facility,

Sanitary and industrial wastewater; and
Equipment and vehicle wash water, including tank cleaning operations.
Sector Specific Control Measures and Effluent Limits.
In addition to the control measures and effluent limits in Part III, the permittee shall implement the following to minimize pollutant discharges, as applicable:
Erosion and Sediment Controls.The permittee shall minimize the discharge of pollutants in stormwater by implementing control measures, such as the following, where feasible:
Routing stormwater to the treatment works; or
Covering exposed materials from the following areas:
Grit, screenings, and other solids handling;
Storage or disposal areas;
Sludge drying beds;
Dried sludge piles;
Compost piles; and
Septage or hauled waste receiving station.
Employee Training. Employee training shall include the following areas, at a minimum, as topics for applicable personnel:

Septage or hauled waste receiving station; and
Access roads and rail lines.
Monitoring Requirements.

Analytical Benchmark Monitoring. There are no analytical benchmark monitoring parameters for Sector T facilities in this permit.Any additional monitoring and reporting requirements shall
be based on the nature of activities at the facility and the facility stormwater discharges, in accordance with Part V.D.2.
Numeric Effluent Limitation Monitoring. There are no numeric effluent limitation parameters for Sector T facilities in this permit.Any additional monitoring and reporting requirements
shall be based on the nature of activities at the facility and the facility stormwater discharges, in accordance with Part V.D.2.
