The Mayor, upon application by a person, may grant a variance or a temporary exemption from the maximum permissible noise levels or time limitations established in the Act when strict compliance with these provisions would impose an undue hardship on the applicant, on the community, or on other persons. The decision of the Mayor shall be in writing and shall include a statement of the reasons for the action taken.
In determining whether or not strict compliance with these provisions would impose an undue hardship, the Mayor shall balance the degree of hardship against the harm that would be caused by the granting of a variance or a temporary exemption. In making this determination, the Mayor shall consider the following:
A variance or temporary exemption shall be granted only to the extent necessary to ameliorate the undue hardship, consistent with the purpose and intent of this Act.
Nothing in this section shall be construed to permit any operation in violation of the Act during the pendency of a request for a variance or a temporary exemption.
Nothing in this section and no variance or temporary exemption shall be construed to prevent or limit the application of the emergency procedures established under § 2711 of this chapter.
