DEPARTMENT
The New Jersey Department of Environmental Protection.
EMERGENCY WORK
Any work or action necessary at the site of an emergency to restore or deliver essential services, including, but not limited to, repairing water, gas, electricity, telephone, sewer facilities, or public transportation facilities, removing fallen trees on public rights-of-way, dredging navigational waterways, or abating life-threatening conditions or a state of emergency declared by a governing agency.
IMPULSIVE SOUND
Either a single pressure peak or a single burst (multiple pressure peaks) that has a duration of less than one second.
MINOR VIOLATION
A violation that is not the result of the purposeful, reckless or criminally negligent conduct of the alleged violator; and/or the activity or condition constituting the violation has not been the subject of an enforcement action by any authorized local, county or state enforcement agency against the violator within the immediately preceding 12 months for the same or a substantially similar violation.
MOTOR VEHICLE

A commercial, residential, industrial or public service property having boilers, incinerators, elevators, automatic garage doors, air conditioners, laundry rooms, utility provisions, or health and recreational facilities, or other similar devices or areas, either in the interior or on the exterior of the building, which may be a source of elevated sound levels at another category on the same distinct parcel of land; or
B. 
A building, which is both commercial (usually on the ground floor) and residential property, located above, below or otherwise adjacent to.
NOISE CONTROL INVESTIGATOR (NCI)
An employee of a municipality, county or regional health commission that has a Department-approved model noise control ordinance and the employee has not received noise enforcement training as specified by the Department in N.J.A.C. 7:29. However, such person is knowledgeable about the model noise ordinance and enforcement procedures. A Noise Control Investigator may only enforce sections of the ordinance that do not require the use of a sound level meter. The employee must be acting within his or her designated jurisdiction and must be authorized to issue a summons.
NOISE CONTROL OFFICER (NCO)
An employee of a local, county or regional health agency which is certified pursuant to the County Environmental Health Act (N.J.S.A. 26:3A2-21 et seq.) to perform noise enforcement activities or an employee of a municipality with a Department-approved model noise control ordinance. All NCOs must receive noise enforcement training as specified by the Department in N.J.A.C. 7:29 and is currently certified in noise enforcement. The employee must be acting within his or her designated jurisdiction and must be authorized to issue a summons.
PLAINLY AUDIBLE
Any sound that can be detected by an NCO or an NCI using his or her unaided hearing faculties of normal acuity. As an example, if the sound source under investigation is a portable or vehicular sound amplification or reproduction device, the detection of the rhythmic bass component of the music is sufficient to verify plainly audible sound. The NCO or NCI need not determine the title, specific words, or the artist performing the song.
PRIVATE RIGHT-OF-WAY

F. 
Self-contained, portable, nonvehicular music or sound production devices shall not be operated on a public space or public right-of-way in such a manner as to be plainly audible at a distance of 50 feet in any direction from the operator between the hours of 8:00 a.m. and 10:00 p.m. Between the hours of 10:00 p.m. and 8:00 a.m., sound, operated on a public space or public right-of-way, from such equipment shall not be plainly audible at a distance of 25 feet in any direction from the operator.
G. 
It shall be unlawful for any property owner or tenant to allow any domesticated or caged animal to create a sound across a real property line which unreasonably disturbs or interferes with the peace, comfort, and repose of any resident, or to refuse or intentionally fail to cease the unreasonable noise when ordered to do so by a Noise Control Officer or Noise Control Investigator.
(1) 
Prima facie evidence of a violation of this section shall include but not be limited to:
(a) 
Vocalizing (howling, yelping, barking, squawking, etc.) for five minutes without interruption, defined as an average of four or more vocalizations per minute in that period; or
(b) 
Vocalizing for 20 minutes intermittently, defined as an average of two vocalizations or more per minute in that period.
(2) 
It is an affirmative defense under this subsection that the dog or other animal was intentionally provoked to bark or make any other noise.

§ 211-10 Motor vehicles.

Violations of each subsection of this section shall be considered purposeful and therefore nonminor violations.
A. 
No person shall remove or render inoperative, or cause to be removed or rendered inoperative or less effective than originally equipped, other than for the purposes of maintenance, repair, or replacement of any device or element of design incorporated in any motor vehicle for the purpose of noise control. No person shall operate a motor vehicle or motorcycle which has been so modified. A vehicle not meeting these requirements shall be deemed in violation of this provision if it is operated stationary or in motion in any public space or public right-of-way.
B. 
No motorcycle shall be operated stationary or in motion unless it has a muffler that complies with and is labeled in accordance with the Federal Noise Regulations under 40 CFR Part 205.
C. 
Personal or commercial vehicular music amplification or reproduction equipment shall not be operated in such a manner that it is plainly audible at distance of 25 feet in any direction from the operator between the hours of 10:00 p.m. and 8:00 a.m.
D. 
Personal or commercial vehicular music amplification or reproduction equipment shall not be operated in such a manner that is plainly audible at a distance of 50 feet in any direction from the operator between the hours of 8:00 a.m. and 10:00 p.m.

§ 211-11 Enforcement.

A. 
Violation of any provision of this chapter shall be cause for a notice of violation (NOV) or a notice of penalty assessment (NOPA) document to be issued to the violator by the Noise Control Officer or Noise Control Investigator.
B. 
Any person who violates any provision of this chapter shall be subject to a civil penalty for each offense of not more than the maximum penalty pursuant to N.J.S.A. 40:49-5, which is $2,000 as of December 2014. If the violation is of a continuing nature, each day during which it occurs shall constitute an additional, separate, and distinct offense.
C. 
Upon identification of a violation of this chapter, the Noise Control Officer or Noise Control Investigator shall issue an enforcement document to the violator. The enforcement document shall identify the condition or activity that constitutes the violation and the specific provision of this chapter that has been violated. It shall also indicate whether the violator has a period of time to correct the violation before a penalty is sought.
D. 
If the violation is deemed by the Noise Control Officer or Noise Control Investigator to be a minor violation (as defined in § 211-2 of this chapter), an NOV shall be issued to the violator.
(1) 
The document shall indicate that the purpose of the NOV is intended to serve as a notice to warn the responsible party/violator of the violation conditions in order to provide him or her with an opportunity to voluntarily investigate the matter and voluntarily take corrective action to address the identified violation.
(2) 
The NOV shall identify the time period (up to 90 days), pursuant to the Grace Period Law, N.J.S.A. 13:1D-125 et seq., where the responsible party's/violator's voluntary action can prevent a formal enforcement action with penalties issued by the NCO or NCI. It shall be noted that the NOV does not constitute a formal enforcement action, a final agency action or a final legal determination that a violation has occurred. Therefore, the NOV may not be appealed or contested.
E. 
If the violation is deemed by the Noise Control Officer or Noise Control Investigator to be a nonminor violation, the violator shall be notified that if the violation is not immediately corrected, an NOPA with a civil penalty of not more than the maximum penalty allowed pursuant to N.J.S.A. 40:49-5, which is $2,000 as of December 2014, will be issued. If a nonminor violation is immediately corrected, an NOV without a civil penalty shall still be issued to document the violation. If the violation occurs again (within 12 months of the initial violation), an NOPA shall be issued regardless of whether the violation is immediately corrected or not.
F. 
The violator may request from the Noise Control Officer or Noise Control Investigator an extension of the compliance deadline in the enforcement action. The Noise Control Officer or Noise Control Investigator shall have the option to approve any reasonable request for an extension (not to exceed 180 days) if the violator can demonstrate that a good faith effort has been made to achieve compliance. If an extension is not granted and the violation continues to exist after the grace period ends, an NOPA shall be issued.
G. 
The recipient of an NOPA shall be entitled to a hearing in a municipal court having jurisdiction to contest such action.
H. 
The Noise Control Officer or Noise Control Investigator may seek injunctive relief if the responsible party does not remediate the violation within the period of time specified in the NOPA issued.
I. 
Any claim for a civil penalty may be compromised and settled based on the following factors:
(1) 
Mitigating or any other extenuating circumstances;
(2) 
The timely implementation by the violator of measures which lead to compliance;
(3) 
The conduct of the violator; and
(4) 
The compliance history of the violator.

§ 211-12 Severability; repealer; effect on other laws.

A. 
If any provision or portion of a provision of this chapter is held to be unconstitutional, preempted by federal or state law, or otherwise invalid by any court of competent jurisdiction, the remaining provisions of the ordinance shall not be invalidated.
B. 
All ordinances or parts of ordinances which are inconsistent with any provisions of this chapter are hereby repealed as to the extent of such inconsistencies.
C. 
No provision of this chapter shall be construed to impair any common law or statutory cause of action, or legal remedy therefrom, of any person for injury or damage arising from any violation of this chapter or from other law.
