(2) A substantial and irretrievable loss of oil or gas resources will occur unless a temporary emergency permit is granted to a Class II well; and
(i) Timely application for a permit could not practicably have been made; and
(ii) The injection will not result in the movement of fluids into underground sources of drinking water; or
(3) A substantial delay in production of oil or gas resources will occur unless a temporary emergency permit is granted to a new Class II well and the temporary authorization will not result in the movement of fluids into an underground source of drinking water.
(b) Requirements for issuance.
(1) Any temporary permit under paragraph (a)(1) of this section shall be for no longer term than required to prevent the hazard.
(2) Any temporary permit under paragraph (a)(2) of this section shall be for no longer than 90 days, except that if a permit application has been submitted prior to the expiration of the 90-day period, the Director may extend the temporary permit until final action on the application.
