ATTACK
Any attack, actual or imminent, or series of attacks by an enemy or foreign nation upon the United States causing, or which may cause, substantial damage or injury to civilian property or persons in the United States in any manner by sabotage or by the use of bombs, shell fire, or nuclear, radiological, chemical, bacteriological, or biological means, or other weapons or processes.
DULY AUTHORIZED DEPUTY
A person authorized to perform all the powers and duties of a public office if the office is vacant, or at such time as it lacks administration, due to the death, absence, or disability of the incumbent officer, where such authorization is provided pursuant to the provisions of any general, special, or local law other than this local law.
EMERGENCY INTERIM SUCCESSOR
A person designated pursuant to this local law for possible temporary succession to the powers and duties, but not the office, of a city officer if neither such officer nor any duly authorized deputy is able, due to death, absence from the city, or other physical, mental, or legal reason, to perform the powers and duties of the office.
PUBLIC DISASTER
A disaster, catastrophe, or emergency, actual or imminent, of such unusual proportions or extent that:
(a) 
A substantial number of the residents of the city either sustain injury, become ill, are infected with disease, have their lives imperiled, are killed, or die as the result of injury, disease, or exposure, or the property of a substantial number of such residents is imperiled, damaged, or destroyed; and
(b) 
It is necessary and essential in the interest of public safety, health, and welfare that the continuity of the government of the city be assured in order that it be enabled to function properly and efficiently and to exercise its essential powers in meeting emergency conditions. Such disasters, catastrophes, and emergencies may include but shall not be limited to conflagrations, explosions, earthquakes, or other convulsions of nature, floods, tidal waves, pestilence, riots, insurrections, storms, prolonged failure of electric power or essential transportation services, or any incident or occurrence which causes or threatens to cause danger to life, health, or property from exposure to noxious materials or radiation.
[L.L. No. 1-1964, § 1]
The state defense emergency act, in section 29-a thereof [Unconsol. L. § 9134.a (McKinney], authorizes political subdivisions of the state to provide for the continuity of their governments in the event of an actual or imminent attack upon the United States by an enemy or foreign nation. General Municipal Law § 60 authorizes political subdivisions to provide for the continuity of their governments in the event of other public disasters, catastrophes, or emergencies. Based on the authority contained in such laws, this local law is adopted so that on such occasions the government of the city may continue to function properly and efficiently under emergency circumstances.
[L.L. No. 1-1964, § 3]

Elective officers. Within 30 days after first entering upon the duties of his office, each elective officer shall, in addition to any duly authorized deputy, designate such number of emergency interim successors to the powers and duties of his office and specify their rank in order of succession after any duly authorized deputy so that there will be not less than three duly authorized deputies, or emergency interim successors, or combination thereof, to perform the powers and duties of the office.
(b) 
Appointive officers. Each officer or body of officers empowered by law to appoint officers shall within the time specified in subsection (a), in addition to any duly authorized deputy, designate for each such appointive officer such number of emergency interim successors to such officers and specify their rank in order of succession after any duly authorized deputy so that there will be not less than three duly authorized deputies, or emergency interim successors, or combination thereof, for each such officer.

Review of designations. The incumbent in the case of those elective officers specified in subsection (a) of this section, and the appointing officer or body of officers specified in subsection (b) of this section shall from time to time review and, as necessary, promptly revise the designations of emergency interim successors to insure that at all times there are at least three duly authorized deputies, or emergency interim successors, or combination thereof, for each elective and appointive officer of the city.

If, in the event of an attack or a public disaster, an officer described in subsection (a) or subsection (b) of section LL2-23 of this local law, or his duly authorized deputy, if any, is unable, due to death, absence from the city, or other physical, mental, or legal reasons, to perform the powers and duties of the office, the emergency interim successor of such officer highest in rank in order of succession who is able to perform the powers and duties of the office shall, except for the power and duty to discharge or replace duly authorized deputies and emergency interim successors of such officer, perform the powers and duties of such officer. An emergency interim successor shall perform such powers and duties only until such time as the lawful incumbent officer or his duly authorized deputy, if any, resumes the office or undertakes the performance of the powers and duties of the office, as the case may be, or until, where an actual vacancy exists, a successor is duly elected or appointed to fill such vacancy and qualifies as provided by law.
[L.L. No. 1-1964, § 5]
The name, address, and rank in order of succession of each duly authorized deputy and emergency interim successor shall be filed with the city clerk, and each designation, replacement, or change in order of succession of any emergency interim successor shall become effective when the designator files with such clerk the successor's name, address, and rank in order of succession. Such clerk shall keep an up-to-date file of all such data regarding duly authorized deputies and emergency interim successors, and such file shall be open to public inspection. The clerk shall notify in writing each designated person of the filing of his name as an emergency interim successor, his rank in order of succession, and also shall notify in writing any person previously designated who is replaced or whose place in order of succession is changed.
[L.L. No. 1-1964, § 6]
