Article I Private Storm Drain Inlet Retrofitting
[Adopted 7-28-2010 by Ord. No. 704]
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 storm sewer system operated by the Borough of Alpine 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, manmade channels, or storm drains) that is owned or operated by the Borough of Alpine or other public body, and is designed and used for collecting and conveying stormwater.
- Any individual, corporation, company, partnership, firm, association or political subdivision of the state subject to municipal jurisdiction.
- STORM DRAIN INLET
- An opening in a storm drain used to collect stormwater runoff including, but not limited to, a grate inlet, curb-opening inlet, slotted inlet, and combination inlet.
- WATERS OF THE STATE
- The ocean and its estuaries, all streams, springs, and bodies or surface or ground water, 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:
Storm drain inlets identified in § 191-3 above shall comply with the following standard to control passage of solid and floatable materials through storm drain inlets. For purposes of this section, "solids and floatable materials" means sediment, debris, trash and other floating, suspended, or settleable solids. For exceptions to this standard see Subsection C below.
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:
The New Jersey Department of Transportation (NJDOT) bicycle safety grate, which is described in Chapter 2.4 of the NJDOP Bicycle Compatible Roadways and Bikeways Planning and Design Guidelines (April 1996); or
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 inches 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.
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.
This standard does not apply:
Where the municipal engineer agrees that this standard would case inadequate hydraulic performance that could not practicably be overcome by using addition or larger storm drain inlets that meet these standards;
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:
Where flows are conveyed through a trash rack that has parallel bars with one-inch spacing between the bars; or
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 historical property.
This article shall be enforced by the Police Department and/or the Property Maintenance Official for the Borough of Alpine.
Any person who is found to be in violation of the provisions of this article shall be subject to a fine not to exceed $500 for a first offense, and $1,000 for each subsequent offense, for each storm drain inlet that is not retrofitted to meet the design standard.
