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 §
308-7B below.
A. Grates;
curb-opening inlets.
(1) Design engineers shall use one 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; 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 system floors used to collect stormwater from the surface
into a storm drain or surface water body.
(3) For curb-opening inlets, including curb-opening inlets in combination
inlets, 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.
B. The standard in Subsection
A above does not apply:
(1) Where each individual clear space in the curb opening in existing
curb-opening inlet does not have an area of more than nine square
inches;
(2) Where the municipality agrees that the standards would cause inadequate
hydraulic performance that could not practicably be overcome by using
additional or larger storm drain inlets;
(3) Where flows from the water quality design storm as specified in N.J.A.C.
7:8 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 rectangular space
4.625 inches long and 1.5 inches wide (this option does not apply
for outfall netting facilities) or a bar screen having a bar spacing
of 0.5 inch. Note that these exemptions do not authorize any infringement
of requirements in the Residential Site Improvement Standards for
bicycle safe grates in new residential development [N.J.A.C. 5:21-4.18(b)2
and 5:21-7.4(b)1];
(4) Where flows are conveyed through a trash rack that has parallel bars
with one-inch spacing between the bars, to the elevation of the water
quality design storm as specified in N.J.A.C. 7:8; or
(5) 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.
