[MC 2009-13, § I, August 17, 2009]
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, 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 City
of Plainfield so as to protect public health, safety and welfare,
and to prescribe penalties for the failure to comply.
[MC 2009-13, § II, August 17, 2009]
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) Municipal separate storm sewer system (MS4) shall mean 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 City of Plainfield
or other public body, and is designed and used for collecting and
conveying stormwater.
(b) Person shall mean any individual, corporation, company, partnership,
firm, association, or political subdivision of this State subject
to municipal jurisdiction.
(c) Storm drain inlet shall mean 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.
(d) Waters of the State shall mean the ocean and estuaries, all springs,
streams and bodies of surface or groundwater, whether natural or artificial,
within the boundaries of the State of New Jersey or subject to its
jurisdiction.
[MC 2009-13, § III, August 17, 2009]
No person in control of private property (except a residential
lot with one (1) single-family house) shall authorize the repaving,
repairing (excluding the repair of individual potholes), resurfacing
(including top coating or chip sealing with asphalt emulsion of 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:
(a) Already meets the design standard below to control passage of solid
and floatable materials; or
(b) Is retrofitted or replaced to meet the standard in Section
12:9-5 below prior to the completion of the project.
[MC 2009-13, § IV, August 17, 2009]
Storm drain inlets identified in Section
12:9-3 above shall comply with the following standard to control passage of solid and floatable materials through storm rain inlets. For purposes of this paragraph, "solid and floatable materials" means sediment, debris, trash, and other floating, suspended, or settleable solids. For exemptions to this standard see Section
12:9-4(c).
(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 (7.0) square inches, or is not greater
than 0.5 inches across the smallest dimension.
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 (2) or more clear spaces) shall have an area of no
more than seven (7.0) square inches, or be no greater than two (2.0)
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:
(A)
A rectangular space four and five-eighths (4 5/8) inches
long and one and one-half (1 1/2) inches wide (this option does
not apply for outfall netting facilities); or
(B)
A bar screen having a bar spacing of 0.5 inch.
(3)
Where flows are conveyed through a trash rack that has parallel
bars with one (1) 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.
