[Added 9-20-2010 by Ord. No. 2010-20]
For the purpose of this article, all existing privately owned
storm drain inlets which are in direct contact with repaving, repairing,
reconstruction, regrading or resurfacing or alterations of facilities
on private property must be retrofitted 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 Township of West Windsor 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 section 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 singular number
include the plural number. The word "shall" is always mandatory and
not merely directory. The definitions below are either the same as
or based on corresponding definitions in the New Jersey Pollutant
Discharge Elimination System (NJPDES) rules at N.J.A.C. 7:14A-1.2.
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 West Windsor 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 surface water 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 shall authorize the
repaving, repairing, resurfacing (including, but not limited to, top
coating or chip sealing with asphalt emulsion or a thin layer of hot
bitumen), reconstructing or altering any surface that is in direct
contact with or in close proximity to an existing storm drain inlet
on that property unless the storm drain inlet either:
Storm drain inlets identified in § 150-35 shall comply with the following standard to control the passage of solid and floatable materials through the 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 § 150-37.
A.Â
Grates.
(1)Â
Property owners and/or their design engineers shall use either of
the following grates whenever they use a grate in pavement or any
other ground surface to collect stormwater from that surface into
a storm drain or surface water body under that grate:
(a)Â
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
(b)Â
A different grate, provided each individual void space in that
grate has an area of no more than 7.0 square inches, and/or is no
greater than 0.5 inch across the smallest dimension.
(2)Â
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.Â
Whenever property owners and/or their design engineers use a curb-opening
inlet, the void space in that curb opening (or each individual void
space, if the curb opening has two or more void spaces) shall have
an area of no more than 7.0 square inches, and/or be no greater than
2.0 inches across the smallest dimension used in calculating the opening
area.
B.Â
Exemptions to the design standards identified in § 150-36:
(1)Â
Where the Township Engineer agrees that this standard would cause
inadequate hydraulic performance that could not practicably be overcome
by using additional and/or larger storm drain inlets that meet these
standards.
(2)Â
Where, prior to discharge to waters of the state, 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)Â
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.
