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 systems operated by the Borough of Oaklyn 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.
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 Borough of Oaklyn or other public body, and is designed and
used for collecting and conveying stormwater.
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 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 or 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 §
111-42 below, prior to the completion of the project.
Storm drain inlets, identified in §
111-41 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 §
111-42C 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 the surface into a storm drain or surface water body
under the 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 inch 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 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 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.
