The following requirements apply to this <br /> "Potable Water Startup Phase" : <br /> (i) The potable water startup test shall last a minimum of eight (8) <br /> hours. <br /> (ii) The flow rate shall be at a minimum of 100 gpm, and shall be <br /> increased to 500 gpm for at least two (2) continuous hours. <br /> (iii) The steady state reinjection capacity of the three injection <br /> wells shall be determined. The injection field shall be <br /> monitored per the "8-Hour Potable Water Startup Phase <br /> Monitoring" plan in the attached Monitoring and Reporting <br /> Program No. 90- <br /> ( iv) All treatment, transport, and disposal components (including <br /> pumps, valves, liquid level controllers, pipelines, blowers, <br /> flow meters, pressure gauges, etc. ) shall be inspected for leaks <br /> and/or malfunctions.

(above). The following requirements apply to this <br /> "Contaminated Water Startup" phase: <br /> (i) All extracted ground water shall be treated by the air stripper <br /> facility and discharged to the storm drain holding pond only. <br /> Discharge to the injection wells is prohibited. <br />
