Discharge to Ground Water Permitting Program
Any facilities that
discharge pollutants to ground waters of the State require
a New Jersey Pollutant Discharge Elimination System
(NJPDES) - Discharge to Ground Water (DGW) permit.
The state rule that sets forth the requirements
on elibility, procedures for obtaining, and general
conditions for maintaining a NJPDES-DGW permit are
in N.J.A.C. 7:14A. The goal of the NJPDES-DGW permitting
program is to restore, enhance and maintain the
ground water quality of New Jersey. This goal is
achieved pursuant to the WPCA and the Ground Water
Quality Standards (GWQS), which can be found at
N.J.A.C. 7:9C et seq. The GWQS designate ground
water classifications throughout the state, designated
uses, and ground water quality criteria and constituent
and General Permitting for DGW Permits
NJPDES-DGW permits may
be in the form of an Individual or General Permit.
Individual permits are tailored to the specific
conditions of a facility’s operation and
are typically issued to facilities with multiple
operations, complex site organization, or for
those facilities that are not eligible for a general
permit. Individual permits provide a facility
the flexibility of utilizing custom best management
practices (BMPs), in addition to site-specific
monitoring and sampling requirements to track
the discharge of pollutants into underlying aquifers.
For more information on individual permits, visit
the Types of Individual DGW Permits section.
NJPDES-DGW general permits
are pre-approved permits a facility may request
authorization under if the facility conforms to
the eligibility requirements of that particular
general permit. Typically, this eligibility requires
a facility to enact certain operating procedures
and wastewater handling methods that the Department
has deemed satisfactory to meet the NJPDES rule
and the Ground Water Quality Standards. Types
of general permits include the Lined Surface Impoundment
(LSI) General Permit, Sanitary Subsurface Disposal
(T1) General Permit, and those general permits
that provide for the proper discharge of wastewater
from specific industries. For more information
on general permits, visit the General Permits section of the BNPC website.
