The minimum separation distance between the various
components of the system and the other features listed shall conform to and be
maintained in accordance with Table 4.3 below. The location of a new well must
be in conformance with the requirements of N.J.A.C. 7:9D. No
permit or waiver issued outside of this chapter by any local, State or Federal
entity shall be construed to permit deviation from or a waiver of the
separation distances requirements listed in the Table 4.3 below.

<(1)> This distance may be increased as determined by a
local, State or Federal entity having authority for establishing separation
distances, including, but not limited to, wetlands protection, stream
encroachment and riparian corridor.
<(2)> Where excessively coarse soils or fractured rock
substrata are encountered, these distances may be increased by the
administrative authority.
<(3)> This distance may be decreased only in the case
of an interceptor drain allowed in N.J.A.C 7:9A-10.7(d).
<(4)> This distance may be decreased by the
administrative authority, to a minimum of 50 feet when either the well is
provided with a water-tight casing to a depth of 100 feet or more, or where the
casing is sealed into an impervious stratum which separates the waterbearing
stratum from the layer of soil used for sanitary sewage disposal.
N.J.A.C. 7:9D shall govern whenever the well under
consideration has been installed after July 13, 1979.
<(5)> These distances may be reduced by one-half if the
water course is a footing drain with an invert elevation higher than the bottom
of the disposal field or more than four feet above the level of the seasonally
high water table.
<(6)> May be reduced to five feet with special
approval of the administrative authority.
<(7)> May be reduced to 15 feet from disposal field
and 30 feet from seepage pit for portions of the building constructed either on
a slab foundation or over a continuous dust cap which is at or above natural or
finished grade, whichever is higher only.
<(8)> This distance applies to disposal fields serving
separate realty improvements but not to disposal fields which are part of a
split system serving a single realty improvement.
<(9)> Applies only to seepage pits allowed as
prescribed in
N.J.A.C.
7:9A-7.6.
<(10)> In no case shall the distance be less than three
times the pit diameter.
<(11)> These distances shall be measured from the
outermost margin of the disposal bed or trench in the case of conventional and
soil replacement bottom-lined installations, from the outermost lateral
extension of suitable fill in the case of soil replacement fill-enclosed and
mounded soil replacement installations, or the edge of the required lateral
suitable fill extension in the case of mounded installations.
<(12)> For the purposes of this section, the setback
distance for a water course shall apply to a stormwater management basin. The
setback distance from a stormwater management basin shall be measured from the
elevation contour that is coincident with the high water mark.
<(13)> The setback distance from a seepage pit shall be
150 feet from a well and 100 feet from a suction line.
<(14)> For the purposes of measuring separation
distance requirements, a D-Box shall include all piping and appurtenances
associated with the effluent distribution network from the outlet of the septic
tank to the disposal area.
<(15)> This separation distance requirement may be
reduced to zero feet in cases where either of the following is provided to the
administrative authority prior to obtaining a construction approval for the
infringing system or its component:
i.
If the property line abuts a roadway or utility easement on the side of the
property where the reduction in the separation distance is being sought and
there are no subsurface utilities located within the separation distance
specified in Table 4.3, a notarized statement from the owner of record of the
roadway or utility easement acknowledging that no subsurface utilities will be
installed within that area; or
ii.
A copy of a deed notice prepared in accordance with the New Jersey Recording
Act, N.J.S.A. 46:15-1.1 et seq.,
recorded with the office of the clerk or the registrar of deeds and mortgages
of the county in which the property where the system is located for each
affected property indicating that the affected property owner(s) allow for the
reduction in the required separation distance, detailing the reduction in the
required separation distance and acknowledging that future improvements may be
limited on each affected property based on the reduced separation distance
granted due to the need to maintain other setbacks, including but not limited
to those for in-ground swimming pools and occupied buildings. The deed notice
shall run with the property and be binding upon the property owner and the
successors in interest in the property or in any part thereof.
