§ 13-1514. Disposal/injection wells.

(a)

Every such disposal or injection well shall be constructed so as to seal the injection zone from the upper portion of the casing. The annulus between the injection tubing and the casing shall be filled with a noncorrosive fluid, then sealed, and a one-fourth-inch female fitting with cut-off valve shall be attached so that the pressure in the annulus may be measured by the Oil and Gas Inspector by attaching a gauge having a one-fourth-inch male fitting. A pressure shall be maintained in the annulus of not less than twenty-five (25) psi at all times to insure the integrity of the packer, tubing and casing. Any significant deviation from the established pressure shall be cause to shut down the well and may result in cancellation of the operating permit until such time as the established pressure can once again be maintained.

(b)

Injection lines installed after the effective date of Ordinance 0-1415-7 shall be buried in a trench of a depth so that the top of the pipe is no less than three (3) feet, and shall be pressure tested (static) annually, at a minimum of one hundred fifty (150) percent of the pressure normally encountered at the injection pump discharge, for a period of one (1) hour. The Oil and Gas Inspector shall be notified forty-eight (48) hours in advance of such test and may supervise same. Test results shall be filed with the City upon completion. All non-steel lines shall have tracer wire installed and all lines shall have signs at all property lines and public and private street crossings.

(c)

Domestic and public water supply wells located within a radius of one-quarter (¼) mile of any enhanced recovery or disposal well shall be tested prior to beginning injection or disposal and thereafter annually for the presence of deleterious substances. The substances to be tested for are: bromide, chloride, total dissolved solids, methane, iron, manganese, arsenic, boron, and lithium. Such testing is the responsibility of the permittee and, at the permittee's expense, to be conducted by a person or company approved by the Oil and Gas Inspector. The Oil and Gas Inspector and the water well owner shall be notified forty-eight (48) hours in advance of such testing and may be present. Test results shall be filed with the City upon completion.
