refrigeration-grade copper pipe as defined/described in ASTM B280-08, which is <br /> hereby incorporated by reference, including subsequent amendments and editions. <br /> 8.All Direct Expansion systems shall be constructed with catholic protection unless <br /> testing conducted in accordance with Part C (9) (c) of this Section indicates that all <br /> pH test results are within the range of 5.5 to 11.0 standard units. Catholic <br /> protection, if required, shall be maintained at all times in accordance with the <br /> manufacturer's specifications throughout the operating life of the well(s). <br /> 9.Testing requirements are as follows: <br /> a)Closed loop tubing shall pass a pressure test on-site prior to installation <br /> into the borehole. Any closed loop tubing that has a measurable leak shall either <br /> not be used or have the leaks located and repaired plus successfully pass a <br /> subsequent pressure test prior to installation. <br /> b)The closed loop well system shall pass a pressure test after installation and <br /> prior to operation. Any pressure fluctuation other than that due to thermal <br /> expansion and contraction of the testing medium shall be considered a failed <br /> test. Any leaks shall be located and repaired prior to operating the system. <br /> c) For Direct Expansion type wells, drilling cuttings shall be tested for pH at a <br /> frequency of at least every 10 feet of boring length using a pH meter that has <br /> been calibrated prior to use according to the manufacturer's instructions. A copy <br /> of the results of these tests shall be made available to the Orange County <br /> Health Department. <br /> 10. The well(s) shall be grouted within seven days after drilling is complete or before Comment[VH7o]:CLARIFIES MONITORING <br /> the drilling equipment leaves the site,whichever occurs first. The well contractor WELL GROUTING INSPECTION PROCESS <br /> shall give the OCHD at least 24 hours prior notification if more than three closed-loop <br /> geothermal wells are to be grouted in a given day. Prior to the initiation of the <br /> grouting process, the OCHD will verify that the locations of all geothermal wells meet <br /> all applicable setbacks. The OCHD may conduct intermittent inspections of the <br /> grouting process thereafter, and shall ensure by visual inspection that each well is <br /> grouted to within one foot of land surface. The well contractor must submit a <br /> completed, signed copy of a Well Construction Record (GW-1)to the OCHD for all <br /> wells grouted at each inspection. If identical, all the wells grouted on a given <br /> occasion may be listed on the same form. The form shall be submitted to the OCHD <br /> within 3 working days of the grout inspection. <br /> 11. The well(s) shall be operated and maintained in accordance with the <br /> manufacturer's specifications throughout the operating life of the well(s). <br /> 12. When closed loop geothermal heat exchange injection wells are terminated below <br /> the ground surface,either: <br /> a)Each well shall have a permanent monument at grade level directly above <br /> each well. The monument shall state <br /> 36 <br />
