Upon good cause shown by the owner or responsible party for any noise source, the City Manager shall have the power to grant an exemption from the requirement of this article in order to allow sufficient time for installation of needed control equipment, facilities, or modifications to achieve compliance, not to exceed ten (10) days, provided that such exemption may be renewed as necessary, but only if satisfactory progress toward compliance is shown.

   (d)    Special Waivers.
      (1)    The City Manager shall have the authority, consistent with this article, to grant special waivers to the provisions of this article.
       (2)    Any person seeking a special waiver pursuant to this article shall file a written application with the City Manager. The written application shall contain information which demonstrates that bringing the source of sound or activity for which the special waiver is sought into compliance with this article would constitute an unreasonable hardship on the applicant, on the community, or for another purpose.
       (3)    Any person seeking such a special waiver shall indicate in his or her application to the City Manager the specific reason why he or she will not be able to meet the established noise levels. The applicant shall also include a written statement that he or she has personally contacted all residents of properties within 400 feet of the property in question and none oppose the special waiver being requested. The applicant will also be required to notify and receive permission from applicant's landlord, if the property in question is a rental property.
      (4)    In determining whether to grant or deny the application, the City Manager shall balance the hardship to the applicant, the community, and other persons of not granting the special waiver against the adverse impact on the health, safety and welfare of persons affected, and the adverse impact of granting the special waiver.
       (5)    Special waivers shall be granted by notice to the applicant and may include all necessary conditions, including time limits on the permitted activity. The special waiver shall not become effective until all conditions are agreed to by the applicants. Noncompliance with any condition of the special waiver shall automatically terminate it and subject the person holding it to those provisions of this article regulating the source of sounds or activity for which the special waiver was granted.

       (2)    Should the applicant be granted a special waiver pursuant to this subsection, it will be subject to the condition that any such special waiver will expire at 10:00 p.m. on Sunday through Thursday evenings and midnight on Friday and Saturday evenings.
