(a) 
The city council, within (30) days after the filing of the application for a permit to drill and operate a well, shall determine whether or not said application complies in all respects with the provisions of this article; and if it does, the city council shall then fix the amount of the principal of the bond and insurance provided for in section 4.02.008 herein and after such determination shall issue a permit for the drilling and operation of the well applied for.

(3) 
Contain and specify that the term of such permit shall be for a period of one year from the date of the permit and as long thereafter as the permittee is engaged in drilling operations with no cessations of such operations for more than (90) ninety days, or oil or gas is produced in commercial quantities from the well drilled pursuant to such permit; provided that, if at any time after discovery of oil or gas the production therein in commercial quantities shall cease, the term shall not terminate if the permittee commences additional reworking operations within ninety (90) days thereafter, and if they result in the production of oil or gas, so long thereafter as oil or gas is produced in commercial quantities from said well;
(4) 
Contain and specify such conditions as are by this article authorized;
(5) 
Specify the total depth to which the well may be drilled, not exceeding the projected depth; and

If the permit for the well be refused, or if the applicant notifies the city council in writing that he does not elect to accept the permit as tendered and wishes to withdraw his application, or if the bond of the applicant be not approved and the applicant notifies the city council in writing that he wishes to withdraw his application, then upon the happening of said events, the cash deposit provided for to be filed with the application shall be returned to the applicant, except that there shall be retained therefrom by the city one hundred dollars ($100.00) as a processing fee.
(1995 Code, sec. 7-6)
When a permit shall have been issued, the same shall terminate and become inoperative without any action on the part of the city unless, within ninety (90) days from the date of issuance, actual drilling of the well shall have commenced. The cessation for a like period of the drilling operations or the cessation of the production of oil or gas from the well after production shall have commenced shall operate to terminate and cancel the permit, and the well shall be considered as abandoned for all purposes of this article, and it shall be unlawful thereafter to continue the operation or drilling of such well without the issuance of another permit.
(1995 Code, sec. 7-7)
In the event a permit is issued by the city council under the terms of this article for the drilling and operation of a well, no actual drilling operations shall be commenced until the permittee shall file with the city secretary a bond and a certificate of insurance, as follows:

Said bond shall become effective on or before the date the same is filed with the city secretary and remain in force and effect for at least a period of six (6) months subsequent to the expiration of the term of the permit issued; and in addition the bond will be conditioned that the permittee will promptly pay off fines, penalties and other assessments imposed upon permittee by reason of his breach of any of the terms, provisions and conditions of this article; and that permittee will promptly restore the streets and sidewalks and other public property of the city, which may be disturbed or damaged in the operations, to their former condition; and that the permittee will promptly clear all premises of all litter, trash, waste, and other substances used, allowed or occurring in the drilling or producing operations, and will after abandonment grade, level and restore said property to the same surface condition, as nearly as possible, as existed when operations for the drilling of the well or wells were first commenced; and that the permittee will indemnify and hold the city harmless from any and all liability growing out of or attributable to the granting of such permit. If at any time the city council shall deem any permittee’s bond to be insufficient for any reason, it may require the permittee to file a new bond.
If, after completion of a well, permittee has complied with all of the provisions of this article, such as to removing derrick, clearing premises, etc., he may apply to the city council to have said bond reduced to a sum of not less than $10,000.00 for the remainder of the time said well produces without reworking. During reworking operations, the amount of the bond shall be increased to the original amount.
(2) 
In addition to the bond required in subsection (1) of this section, the permittee shall carry a policy or policies of standard comprehensive public liability insurance, including contractual liability, covering bodily injuries and property damage, naming the permittee and the city, in an insurance company authorized to do business within the state.

Said insurance policy or policies shall not be cancelled without written notice to the city secretary at least ten (10) days prior to the effective date of such cancellation. In the event said insurance policy or policies are cancelled, the permit granted shall terminate, and permittee’s rights to operate under said permit shall cease until permittee files additional insurance as provided herein.
If, after completion of a well, permittee has complied with all of the provisions of this article, such as to removing derrick, clearing premises, etc., he may apply to the city council to have said insurance policies reduced as follows:
