The Bureau of Pretreatment and Residuals is responsible for overseeing the administration of delegated to local agency pretreatment programs for issuing SIU permits for discharges into treatment works of non-delegated local agencies.

Annual reports are required to be submitted by local agencies indicating the status of dischargers to local agency sewer plants and of the local agency's pretreatment program. Guidance is available for Delegated Local Agencies and is also included in NJDEP's "Guidance Manual for Pretreatment Program Compliance for Non-Delegated Local Agencies."

Applicable Pretreatment Program Requirements for Publicly Owned (Sewage) Treatment Works (POTWs) are included in NJPDES Permits issued by the Bureaus of Point Souce Permitting 1 and 2, or by the Bureau of Non-Point Pollution Control.
