BOP Program Statement 1605.01 § 13

Industrial wastewater must not be discharged unless the proper permits are obtained from

federal, state, or local authorities.

a. Point Source Discharge. Point-source industrial wastewater discharges into a storm sewer,

ditch, or other conveyance require either NPDES or a state discharge permit. Example:

Discharging vehicle wash rack wastewater into a ditch.

b. Publicly Owned Treatment Works (POTW). Discharges into a POTW require local or state

permits or must meet certain regulatory requirements. Example: Wastewater discharged from a

spray booth metal pretreatment process may require a state or local permit to discharge, but

dental clinic waste discharges may be addressed in a specific regulation or code requiring

installation and maintenance of a mercury trap/filter system.

All discharges, excluding domestic sewage, must be communicated to the POTW to ensure they

are in compliance with local pretreatment standards. Department heads must provide the SA the

chemical name and constituents, volume discharged, and frequency discharged from the

pertinent departments and relay the information to the POTW. All new discharges must be

communicated to the POTW prior to discharge. Communications regarding these discharges

must be documented.
