A request for exemption shall be filed in writing with the City Administrator.
C. 
Special waivers.
(1) 
The City Administrator shall have the authority, consistent with this chapter, to grant special waivers for good cause shown by an applicant.
(2) 
Any person seeking a special waiver pursuant to this chapter shall file a written application with the City Administrator. 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 chapter would constitute an unreasonable hardship on the applicant, on the community or for another purpose. The written application shall set forth the date and hours between which such use or activity is to be extent, the nature of the use or activity and any noise-creating equipment to be employed, as well as the name, address and telephone number of the person to be responsible for the operation thereof.
(3) 
In determining whether to grant or deny the application, the City Administrator 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, the adverse impact of property affected and any other adverse impacts of granting the special waiver.
(4) 
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 applicant. Noncompliance with any condition of the special waiver shall terminate it and subject the person holding it to those provisions of this chapter regulating the source of sounds or activity for which the special waiver was granted.
(5)

(a) 
Residence districts: 57 dBA between the hours of 7:00 a.m. and 9:00 p.m.; 52 dBA between the hours of 9:00 p.m. and 8:00 a.m.

B. 
When any person designated to enforce this chapter decides to use a noise level meter, the ambient noise level shall be obtained by one of two methods:

Severability. It is hereby declared to be the policy of the City of New Castle that if the sections, paragraphs, sentences, clauses and phrases of this chapter shall be declared unconstitutional or invalid by the valid judgment or decree of any court of competent jurisdiction, such unconstitutionality or invalidity shall not affect any of the remaining sections, paragraphs, sentences, clauses and phrases of the chapter.
B. 
For the purpose of the enforcement of the provisions of this chapter, when used, a sound level meter shall meet or exceed the requirements of the American National Standard Institute specifications for sound level meters (ANSI IS.4-197 1), approved April 17, 1971, and issued by the American National Standard Institute for Types I, II or S sound level meters.
