The types of facilities regulated include: mines, pits and quarries; schools and hospitals; potable water treatment plants; large corporate office buildings; industrial manufacturing facilities; campgrounds and mobile home parks; food processors; and sewage treatment plants and other discharges of wastewater that can impact ground water.
The Bureau of Nonpoint Pollution Control also coordinates the Underground Injection Control (UIC) Program for New Jersey. Underground injection systems include a number of different types of subsurface disposal systems such as: sanitary septic systems that do not conform to the Standards for the Construction of Individual Subsurface Sewage Disposal Systems (N.J.A.C. 7:9A); any septic system receiving industrial wastewater; true wastewater injection wells; subsurface trench systems; dry wells; seepage pits; etc. In New Jersey, the UIC program is managed under the umbrella of the NJPDES Discharge to Ground water Program, and there is no individual unit called the UIC program.
Discharges that are not regulated by the Division of Water Quality and its NJPDES program are probably regulated by either the Site Remediation Program, or by the Division of Solid and Hazardous Waste. These discharges are from past activities such as spills, or from the impact of non-operating or closed landfills. These discharges must obtain pollution control approvals such as MOAs or voluntary cleanups, from the relevant group in either of those programs. The types of discharges not covered by the DWQ NJPDES program are:
- Past Discharges and the subsequent leaching of metals and petroleum product from contaminated soils
- Monitoring at officially closed Sanitary landfills (Division of Solid and Hazardous Waste)
- Underground storage tanks and remediation associated with them
- ISRA contaminated sites
