[Adopted 10-6-2009 by Ord. No. 2009-005]
The purpose of this article is to require the retrofitting of
existing storm drain inlets which are in direct contact with repaving,
repairing, reconstruction or resurfacing or alterations of facilities
on private property and to prevent the discharge of solids and floatables
(such as plastic bottles, cans, food wrappers and other litter) to
the municipal separate storm sewer system(s) operated by the Shamong
Township so as to protect public health, safety and welfare and to
prescribe penalties for the failure to comply.
For the purpose of this article, the following terms, phrases,
words and their derivations shall have the meanings stated herein
unless their use in the text of this article clearly demonstrates
a different meaning. When not inconsistent with the context, words
used in the present tense include the future, words used in the plural
number include the singular number, and words used in the singular
number include the plural number. The word "shall" is always mandatory
and not merely directory.
A conveyance or system of conveyances (including roads with
drainage systems, municipal streets, catch basins, curbs, gutters,
ditches, man-made channels or storm drains) that is owned or operated
by the Township of Shamong or other public body and is designed and
used for collecting and conveying stormwater.
Any individual, corporation, company, partnership, firm,
association or political subdivision of this state subject to municipal
jurisdiction.
An opening in a storm drain used to collect stormwater runoff,
and includes, but is not limited to, a grate inlet, curb-opening inlet,
slotted inlet and combination inlet.
The ocean and its estuaries, all springs, streams and bodies
of surfacewater or groundwater, whether natural or artificial, within
the boundaries of the State of New Jersey or subject to its jurisdiction.
No person in control of private property (except a residential
lot with one single-family house) shall authorize the repaving, repairing
(excluding the repair of individual potholes), resurfacing (including
top coating or chip sealing with asphalt emulsion or a thin base of
hot bitumen), reconstructing or altering any surface that is in direct
contact with an existing storm drain inlet on that property unless
the storm drain inlet either:
Storm drain inlets identified in § 147-21 above shall comply with the following standard to control passage of solid and floatable materials through storm drain inlets. For purposes of this section, "solid and floatable materials" means sediment, debris, trash and other floating, suspended or settleable solids. For exemptions to this standard see Subsection C below.
A.
Design engineers shall use either of the following grates whenever
they use a grate in pavement or another ground surface to collect
stormwater from that surface into a storm drain or surface water body
under that grate:
(1)
The New Jersey Department of Transportation (NJDOT) bicycle-safe
grate, which is described in Chapter 2.4 of the NJDOT Bicycle Compatible
Roadways and Bikeways Planning and Design Guidelines (April 1996);
or
(2)
A different grate, if each individual clear space in that grate has
an area of no more than seven square inches or is no greater than
0.5 inches across the smallest dimension.
(3)
Examples of grates subject to this standard include grates in grate
inlets, the grate portion (non-curb-opening portion) of combination
inlets, grates on storm sewer manholes, ditch grates, trench grates
and grates of spacer bars in slotted drains. Examples of ground surfaces
include surfaces of roads (including bridges), driveways, parking
areas, bikeways, plazas, sidewalks, lawns, fields, open channels and
stormwater basin floors.
B.
Whenever design engineers use a curb-opening inlet, the clear space
in that curb opening (or each individual clear space, if the curb
opening has two or more clear spaces) shall have an area of no more
than seven square inches or be no greater than two inches across the
smallest dimension.
C.
This standard does not apply:
(1)
Where the municipal engineer agrees that this standard would cause
inadequate hydraulic performance that could not practicably be overcome
by using additional or larger storm drain inlets that meet these standards;
(2)
Where flows are conveyed through any device (e.g., end of pipe netting
facility, manufactured treatment device or a catch basin hood) that
is designed, at a minimum, to prevent delivery of all solid and floatable
materials that could not pass through one of the following:
(3)
Where flows are conveyed through a trash rack that has parallel bars
with one-inch spacing between the bars; or
(4)
Where the New Jersey Department of Environmental Protection determines,
pursuant to the New Jersey Register of Historic Places Rules at N.J.A.C.
7:4-7.2(c), that action to meet this standard is an undertaking that
constitutes an encroachment or will damage or destroy the New Jersey
Register listed historic property.
This article shall be enforced by the New Jersey State Police
and/or municipal officials or Township Engineer of Shamong Township.
Any person(s) who is found to be in violation of the provisions of this article shall be subject to a fine not to exceed those limits established by § 1-15 of the Code of the Township of Shamong for each storm drain inlet that is not retrofitted to meet the design standard.
