[HISTORY: Adopted by the Mayor and Council of the Borough of Hopatcong 3-6-2024 by Ord. No. 2-2024. Amendments noted where applicable.]
As used in this chapter, the following terms shall have the meanings indicated:
DE-ICING MATERIALS
Any granular or solid material such as melting salt or any other granular solid that assists in the melting of snow.
IMPERVIOUS SURFACE
A surface that has been covered with a layer of material so that it is highly resistant to infiltration by water.
PERMANENT STRUCTURE
A permanent building or permanent structure that is anchored to a permanent foundation with an impermeable floor, and that is completely roofed and walled (new structures require a door or other means of sealing the access way from wind driven rainfall). A fabric frame structure is a permanent structure if it meets the following specifications:
A. 
Concrete blocks, jersey barriers or other similar material shall be placed around the interior of the structure to protect the side walls during loading and unloading of de-icing materials;
B. 
The design shall prevent stormwater run-on and run through, and the fabric cannot leak;
C. 
The structure shall be erected on an impermeable slab;
D. 
The structure cannot be open sided; and
E. 
The structure shall have a roll up door or other means of sealing the access way from wind driven rainfall.
STORM DRAIN INLET
The point of entry into the storm sewer system.
A. 
Temporary outdoor storage of de-icing materials in accordance with the requirements below is allowed between October 15 and April 15:
(1) 
Loose materials shall be placed on a flat, impervious surface in a manner that prevents stormwater run-through;
(2) 
Loose materials shall be placed at least 50 feet from surface water bodies, storm drain inlets, ditches and/or other stormwater conveyance channels;
(3) 
Loose materials shall be maintained in a cone-shaped storage pile. If loading or unloading activities alter the cone-shape during daily activities, tracked materials shall be swept back into the storage pile, and the storage pile shall be reshaped into a cone after use;
(4) 
Loose materials shall be covered as follows:
(a) 
The cover shall be waterproof, impermeable, and flexible;
(b) 
The cover shall extend to the base of the pile(s);
(c) 
The cover shall be free from holes or tears;
(d) 
The cover shall be secured and weighed down around the perimeter to prevent removal by wind; and
(e) 
Weight shall be placed on the cover(s) in such a way that minimizes the potential of exposure as materials shift and runoff flows down to the base of the pile. Sandbags lashed together with rope or cable and placed uniformly over the flexible cover, or poly-cord nets provide a suitable method. Items that can potentially hold water (e.g., old tires) shall not be used;
(5) 
Containers must be sealed when not in use; and
(6) 
The site shall be free of all de-icing materials between April 16 and October 14.
B. 
De-icing materials should be stored in a permanent structure if a suitable storage structure is available. For storage of loose de-icing materials in a permanent structure, such storage may be permanent, and thus not restricted to October 15 to April 15.
C. 
The property owner, or owner of the de-icing materials if different, shall designate a person(s) responsible for operations at the site where these materials are stored outdoors and who shall document that weekly inspections are conducted to ensure that the conditions of this chapter are met. Inspection records shall be kept on site and made available to the municipality upon request. Residents who operate businesses from their homes that utilize de-icing materials are required to perform weekly inspections.
A. 
Residents may store de-icing materials outside in a solid-walled, closed container that prevents precipitation from entering and exiting the container and which prevents the de-icing materials from leaking or spilling out. Under these circumstances, weekly inspections are not necessary, but repair or replacement of damaged or inadequate containers shall occur within two weeks.
B. 
If containerized (in bags or buckets) de-icing materials are stored within a permanent structure, they are not subject to the storage and inspection requirements of this section. Piles of de-icing materials are not exempt, even if stored in a permanent structure.
C. 
This chapter does not apply to facilities where the stormwater discharges from de-icing material storage activities are regulated under another NJPDES permit.
This chapter shall be enforced by the Police Department, Zoning Official, Municipal Engineer, or DPW Superintendent of the Borough of Hopatcong.
