A. Leak testing permit. A leak testing permit shall be issued by the Oil Services Coordinator for all abandoned wells located within the area of development. Wells shall be tested for gas leakage and visually inspected for oil leakage.
B. Leak testing of wells. A leak test shall be completed utilizing a “GT-43" gas detection meter, or one of comparable quality approved in advance by the Oil Services Coordinator, and shall be conducted by a state licensed geotechnical or civil engineer or state registered environmental assessor, class II, or other as determined necessary by the Oil Services Coordinator. Following all testing and inspection, the test area shall be returned to its previous state and fencing may be required around the area, or the entire site, to the satisfaction of the Oil Services Coordinator.
C. Observation report. The Oil Services Coordinator shall observe the leak test and prepare a leak test observation report documenting the date, time and summary of the testing and confirmation that venting material installation has been completed as described in subsection G below and to the satisfaction of the Oil Services Coordinator.
D. Leak testing report. A leak test report shall be prepared by a state licensed geotechnical or civil engineer or state registered environmental assessor, class II, and shall be submitted to the city for review and approval by the Oil Services Coordinator. A well shall be considered leaking if the leak test report indicates the meter read is greater than 500 parts per million.
F. Retesting. An approved leak test report is only valid for 24 months from city acceptance. If a building permit has not been issued by this time, retesting is required. Following all testing and inspection, the test area shall be returned to its previous state and fencing may be required around the area or the entire site to the satisfaction of the Oil Services Coordinator.
