The following code provisions address 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 Montague,
so as to protect public health, safety and welfare, and to prescribe
penalties for the failure to comply.
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 §
56-34 below prior to the completion of the project.
Storm drain inlets identified in §
56-33 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 §
56-34C 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 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 square inches or is no greater than
0.5 inch across the smallest dimension.
(3) 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.
(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.
The provisions of this article shall be enforced by the Public
Works Department, Code Enforcement, State Police, and/or other municipal
officials of the Township of Montague.
Any person(s) who is found to be in violation of the provisions
of this article shall be subject to a fine not less than $250 nor
more than $1,000 for each storm drain inlet that is not retrofitted
to meet the design standard.
