The Bureau of Surface Water and Pretreatment Permitting regulates facilities discharging domestic and industrial wastewater directly into surface waters of the state as part of the NJPDES program. In addition, the BSWPP also implements the States's Pretreatment Program which is intended to protect local agency sewage treatment plants from non-domestic wastewater which may interfere with treatment processes, contaminate sewage sludge, or pass through sewage treatment plants. Pretreatment Programs are administered by the Department and by Delegated Local Agencies.
Permittees include various industries, federal, state, county, and municipal facilities, private companies, private residential developments, hospitals, and schools. Collectively, the facilities regulated by this bureau serves the wastewater treatment needs of seven million people and hundreds of industries, treating over 15 billion gallons per day of wastewater.
This bureau also conducts water quality, biological, and toxicological analyses and thermal impact and cooling water assessments.
