shall be installed in the injection line immediately upstream of the wellhead to track and document disposal fluid flow rates, and total fluid volumes. For a given injection rate, the injection pressure should remain relatively constant. Input flow volumes shall be crosschecked against injection pressure records to identify any possible divergence in the injection pressure for a given flow rate. A drop in injection pressure without a corresponding reduction in input flow rate would indicate a possible casing, packer, or other failure. (e) Fluid analysis: the injection line shall be equipped with sampling ports and appropriate connections to facilitate periodic collection of fluid samples representative of the injection fluids for chemical analysis. 4. Proposed Changes and Worlcovers. The permittee shall give advance notice to the Director, as soon as possible, of any planned physical alterations or additions to the permitted well. Major alterations or workovers of the permitted well shall meet all conditions as set forth in this permit. A major alteration/workover shall be considered any work performed, which affects casing, packer(s), or tubing. The permittee shall provide all records of well workovers, logging, or other test data to EPA as part of the quarterly report for the period in which the activity was completed. Appendix B contains samples of the appropriate reporting forms. Demonstration of mechanical integrity (tubing/casing annulus pressure test, Appendix G) shall be performed within thirty (30) days of completion of workovers/alterations and prior to resuming injection activities, in accordance with Part II, Section C. 2. (a) of the Permit. L.oggine and Well Testing~ecifications. (a) The operator has obtained a static reservoir pressure measurement using a downhole pressure gage prior to commencing injection; (b) After any workover that involves any remedial cementing of the casing, the operator shall run a new cement bond log (with a gamma ray, travel time curve, casing collaz locator, amplitude curve, and variable density log) that covers the area of the cementing to verify the adequacy of the cement placement. This log will be nm following the guidelines in Appendix D; (c) Before commencement of injection, the operator shall run a baseline temperature survey fmm the base of the surface casing to TD to establish baseline temperature conditions for comparison with subsequent mechanical integrity testing to detect fluid flow adjacent to the casing; EPA Draft Permit No. CO 10932-04664 Page 9 of 77
