Article 13 — SECONDARY RECOVERY OPERATIONS.

A secondary recovery operation is defined as any operation conducted for the purpose of recovering oil or gas from an underground reservoir by means other than the natural pressure which is indigenous to such reservoir, including but not limited to gas injection, water injection, burning, steaming or any combination thereof.

Subject to the provisions of Section 97.13.4., no secondary recovery operation shall be commenced unless and until a Conditional Use Permit has been granted therefor pursuant to the provisions of Section 95.3.36. of this Code. A new Conditional Use Permit should be required for each change in the method of recovery.

Subject to the provisions of Section 97.13.4., the provisions of this Article shall apply to any secondary recovery operation wherein any part of any injection or producing oil well is located in the City or wherein any part of the underground reservoir from which oil is being recovered is located in the City.

a) The provisions of this Article shall not apply to any secondary recovery oil operation conducted in accordance with a unit agreement which has been approved by the State Division of Oil and Gas and has been placed in production as a secondary recovery unit operation prior to July 1, 1977; provided, however, that the provisions of this Article shall apply to any such secondary recovery operation in the event that any wells included therein are redrilled or deepened or any new wells for which drilling permits were not issued before July 1, 1977 are drilled or otherwise included therein.

b) The provisions of this Article shall not apply to any well which is drilled, redrilled or deepened pursuant to a formal written order of the State Supervisor of Oil and Gas issued on an emergency basis for the purpose of preserving the public health or safety or conserving the oil or gas in an underground reservoir.

b) Where a hearing is to be held on an application for a Conditional Use Permit for the drilling of any new wells or the drilling, redrilling or deepening of existing wells for any secondary recovery unit operation placed on production prior to July 1, 1977, notice of such hearing need be sent only to owners of land as shown on the last assessment roll, included within a three hundred (300) foot radius of the exterior boundaries of the drill site from which such new well is to drilled or such existing well is to be redrilled or deepened; provided, however, that the radius of notice shall not be a limitation on the scope of conditions to be imposed on approval of the application.

c) Where a hearing is to be held on an application for a Conditional Use Permit for the drilling of any new wells or the drilling, redrilling or deepening of existing wells for any secondary recovery operation placed on production after July 1, 1977 and for which a Conditional Use Permit has been granted as provided in Section 97.13.2., notice of such hearing need be sent only to owners of land, as shown on the last assessment roll included within a three hundred (300) foot radius of the exterior boundaries of the drill site from which such new well is to be drilled or such existing well is to be drilled or deepened; provided, however, that the radius of notice shall not be a limitation on the scope of conditions to be imposed on approval of the application.
