This article requires 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 Township of Cinnaminson so as to protect
public health, safety and welfare, and to prescribe penalties for
the failure to comply.
As used in this article, the following words shall have the
following meanings. 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.
MUNICIPAL SEPARATE STORM SEWER SYSTEM (MS4)
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 Cinnaminson or other public body, and is designed
and used for collecting and conveying stormwater. Such a system does
not include lakes, basins or man-made water bodies that are not expressly
dedicated to the Township of Cinnaminson, nor piping or conveyances
which connect said lakes, basin or man-made water bodies.
PERSON
Any individual, corporation, company, partnership, firm,
association, or political subdivision of this state subject to municipal
jurisdiction.
STORM DRAIN INLET
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.
WATERS OF THE STATE
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 (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:
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 §
446-21 prior to the completion of the project.
Storm drain inlets identified in §
446-20 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. Grates.
(1) 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:
(a) 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) 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 inch across the smallest dimension.
(2) 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:
(a) A rectangular space 4 5/8 inches long and 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-inch pacing 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.
