[HISTORY: Adopted by the Township Committee of the Township of Hampton 11-28-2023 by Ord. No. 2023-21. Amendments noted where applicable.]
As used in this chapter, the following terms shall have the meanings indicated:
DOMESTIC SEWAGE
Waste and wastewater from humans or household operations.
ILLICIT CONNECTION
Any physical or nonphysical connection that discharges domestic sewage, noncontact cooling water, process wastewater, or other industrial waste (other than stormwater) to the municipal separate storm sewer system operated by the Township of Hampton, unless that discharge is authorized under an NJPDES permit other than the Tier A municipal stormwater general permit (NJPDES Permit Number NJ0141852). Nonphysical connections may include, but are not limited to, leaks, flows, or overflows into the municipal separate storm sewer system.
INDUSTRIAL WASTE
Nondomestic waste, including, but not limited to, those pollutants regulated under Section 307(a), (b), or (c) of the Federal Clean Water Act [33 U.S.C. § 1317(a), (b), or (c)].
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 Hampton or other public body and is designed and used for collecting and conveying stormwater. 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.
NJPDES PERMIT
A permit issued by the New Jersey Department of Environmental Protection to implement the New Jersey Pollutant Discharge Elimination System (NJPDES) rules at N.J.A.C. 7:14A.
NONCONTACT COOLING WATER
Water used to reduce temperature for the purpose of cooling. Such waters do not come into direct contact with any raw material, intermediate product (other than heat) or finished product. Noncontact cooling water may, however, contain algaecides, or biocides to control fouling of equipment such as heat exchangers, and/or corrosion inhibitors.
PERSON
Any individual, corporation, company, partnership, firm, association, organization or a political subdivision of this state subject to municipal jurisdiction.
PROCESS WASTEWATER
Any water which, during manufacturing or processing, comes into direct contact with or results from the production or use of any raw material, intermediate product, finished product, by-product, or waste product. Process wastewater includes, but is not limited to, leachate and cooling water other than noncontact cooling water.
SOLID AND FLOATABLE MATERIALS
Sediment, debris, trash, and other floating, suspended, or settleable solids.
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.
STORMWATER
Water resulting from precipitation (including rain and snow) that runs off the land's surface, is transmitted to the subsurface, is captured by separate storm sewers or other sewerage or drainage facilities or is conveyed by snow-removal equipment.
The spilling, dumping, or disposal of materials other than stormwater to the municipal separate storm sewer system operated by Hampton Township is prohibited. The spilling, dumping, or disposal of materials other than stormwater in such a manner as to cause the discharge of pollutants to the municipal separate storm sewer system is also prohibited. Excepted from the prohibitions of this section are:
A. 
Water line flushing and discharges from potable water sources.
B. 
Uncontaminated groundwater (e.g., infiltration, crawl space or basement sump pumps, foundation or footing drains, rising groundwaters).
C. 
Air-conditioning condensate (excluding contact and noncontact cooling water).
D. 
Irrigation water (including landscape and lawn-watering runoff).
E. 
Flows from springs, riparian habitats and wetlands, water reservoir discharges and diverted stream flows.
F. 
Residential car-washing water and residential swimming pool discharges.
G. 
Sidewalk, driveway and street washwater.
H. 
Flows from firefighting activities.
I. 
Flows from rinsing of the following equipment with clean water:
(1) 
Beach maintenance equipment immediately following its use for its intended purposes; and
(2) 
Equipment used in the application of salt and de-icing materials immediately following salt and de-icing material applications. Prior to rinsing with clean water, all residual salt and de-icing materials must be removed from equipment and vehicles to the maximum extent practicable using dry cleaning methods (e.g., shoveling and sweeping). Recovered materials are to be returned to storage for reuse or properly discarded.
Rinsing of equipment, as noted in the above situation, is limited to exterior, undercarriage, and exposed parts and does not apply to engines or other enclosed machinery.
No person shall discharge or cause to be discharged through an illicit connection to the municipal separate storm sewer system operated by Hampton Township any domestic sewage, noncontact cooling water, process wastewater, or other industrial waste (other than stormwater).
A. 
Prohibited conduct. 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:
(1) 
Already meets the design standards in Subsection B of this section to control passage of solid and floatable materials; or
(2) 
Is retrofitted or replaced to meet the standards in Subsection B of this section prior to the completion of the project.
B. 
Design standards. Storm drain inlets subject to Subsection A of this section shall comply with the following standards to control passage of solid and floatable materials through storm drain inlets:
(1) 
Grates.
(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 five inch across the smallest dimension.
(b) 
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.
(2) 
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.
(3) 
The design standards set forth in § 90-4B do not apply where:
(a) 
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;
(b) 
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:
[1] 
A rectangular space 4 5/8 inches long and 1 1/2 inches wide (this option does not apply for outfall netting facilities); or
[2] 
A bar screen having a bar spacing of five inch;
(c) 
Flows are conveyed through a trash rack that has parallel bars with one-inch spacing between the bars; or
(d) 
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.
Any person violating or failing to comply with any of the provisions of this chapter shall, upon conviction thereof, be subject to the penalties provided for in Chapter 1, General Provisions, § 1-14.1. Each day such violation is committed or permitted to continue shall constitute a separate offense and shall be punishable as such.
