[Adopted 10-5-2009 by Ord. No. 2009-12]
An article requiring 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 Delanco 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 Township of Delanco or other public body, and is designed and
used for collecting and conveying stormwater. NOTE: In municipalities
with combined sewer systems, MS4s do not include combined sewer systems,
which are sewer systems that are designed to carry sanitary sewage
at all times and to collect and transport stormwater from streets
and other sources.
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 of 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 §
247-4 below prior to the completion of the project.
Storm drain inlets identified in §
247-3 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 §
247-4C 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 7.0 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 7.0 square inches, or be no greater than 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 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.
This article shall be enforced by the Police Department and/or
Code Enforcement Officer of the Township of Delanco.
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 the maximum
amount allowed by the Delanco Code for each storm drain inlet that
is not retrofitted to meet the design standard.
