40 CFR 147.2906 - Emergency permits.
(a) An emergency permit may be issued if:
(1) There will be an imminent health hazard unless an emergency permit is issued; or
(2) There will be a substantial and irretrievable loss of oil and gas resources, timely application for a permit could not practicably have been made, and injection will not result in movement of fluid into an USDW; or
(i) Emergency permits issued to avoid an imminent health threat may last no longer than the time necessary to prevent the hazard.
(ii) Emergency permits issued to prevent a substantial and irretrievable loss of oil or gas resources shall be for no longer than 90 days, unless a complete permit application has been submitted during that time; in which case the emergency permit may be extended until a final decision on the permit application has been made.
(iii) Emergency permits to avoid a substantial delay in oil or gas production shall be issued only after a complete permit application has been submitted and shall be effective until a final decision on the permit application is made.
