[Ord. #1738]
This chapter may be cited as the "Lyndhurst Noise Control Code."
[Ord. #1738]
Excessive sound and vibration are a serious hazard to the public health and welfare, safety, and the quality of life. A substantial body of science and technology exists by which excessive sound and vibration may be substantially abated. The people have a right to and should be ensured an environment free from excessive sound and vibration that may jeopardize their health or welfare or safety or degrade the quality of life. It is the policy of the Township of Lyndhurst to prevent excessive sound and vibration which may jeopardize the health, welfare or safety of its citizens or degrade the quality of life.
[Ord. #1738]
This chapter shall apply to the control of all sound and vibration originating within the limits of the Township of Lyndhurst.

b.
Any person seeking a special variance pursuant to this section shall file an application with the noise control officer. The application shall contain information which demonstrates that bringing the source of sound or activity for which the special variance is sought into compliance with this chapter would constitute an unreasonable hardship on the applicant, on the community, or on other persons. Notice of an application for a special variance shall be published at least once in the official newspaper of the township. Any individual who claims to be adversely affected by allowance of the special variance may file a statement with the noise control officer containing information to support his claim. If the noise control officer finds that a sufficient controversy exists regarding an application, a public hearing may be held.
c.
In determining whether to grant or deny the application, the noise control officer shall balance the hardship to the applicant, community, and other persons of not granting the special variance against the adverse impact on the health, safety, and welfare of persons affected, and the adverse impact on property affected, and any other adverse impacts of granting the special variance.

In granting or denying an application the noise control officer shall place on public file a copy of the decision and the reasons for denying or granting the special variance.
d.
Special variances shall be granted by notice to the applicant containing all necessary conditions, including a time limit on the permitted activity. The special variance shall not become effective until all conditions are agreed to by the applicant. Noncompliance with any condition of the special variance shall terminate it and subject the person holding it to those provisions of this chapter regulating the source of sound or activity for which the special variance was granted.
e.
Application for extension of time limits specified in special variances or for modification of other substantial conditions shall be treated like applications for initial special variances under paragraph b of this subsection.

The noise control officer shall have the authority, consistent with this section, to grant a variance, not to exceed 120 days from the effective date of this chapter.
b.
Any person seeking a variance in time to comply shall file an application with the noise control officer. The application shall contain information which demonstrates that bringing the source of sound or activity for which the variance is sought into compliance with this chapter prior to the date requested in the application would constitute an unreasonable hardship on the applicant, on the community, or on other persons. Notice of an application for a variance in time to comply shall be published at least once in the official newspaper of the township. Any individual who claims to be adversely affected by allowance of the variance in time to comply may file a statement with the noise control officer containing any information to support his claim. If the noise control officer finds that a sufficient controversy exists regarding an application, a public hearing may be held.
c.
In determining whether to grant or deny the application, the noise control officer shall balance the hardship to the applicant, the community, and other persons of not granting the variance in time to comply against the adverse impact on health, safety, and welfare of persons affected, the adverse impact on property affected, and any other adverse impacts of granting the variance. Applications for variances in time to comply and persons contesting variances may be required to submit any information the noise control officer may reasonably require. In granting or denying an application, the noise control officer shall place on public file a copy of the decision and the reasons for denying or granting the variance in time to comply.
d.
Variances in time to comply shall be granted to the applicant containing all necessary conditions, including a schedule for achieving compliance. The variance in time to comply shall not become effective until all conditions are agreed to by the applicant. Noncompliance with any condition of the variance shall terminate the variance and subject the person holding it to those provisions of this chapter for which the variances was granted.
e.
Application for extension of time limits specified in variances in time to comply or for modification or other substantial conditions shall be treated like applications for initial variances under paragraph b of this subsection, except that the noise control officer must find that the need for the extension or modification clearly outweighs any adverse impacts of granting the extension or modification.
f.
The noise control officer may issue guidelines defining the procedures to be followed in applying for a variance in time to comply and the criteria to be considered in deciding whether to grant a variance.
[Ord. #1738]
Appeals of an adverse decision of the noise control officer shall be made to the appropriate court of law. Review of the court shall be de novo.
