RDSI SECTION <br />REG. CITATION <br />RESPONSE <br />t- REFERENCE <br />amendment will be filed at the time of final design of each <br />Appendix B, <br />phase. The existing monitoring system layout and well logs <br />CEP Dwg. P1 <br />are in Appendix P. <br />Appendix P <br />VI.B.2.

A RDSI <br />amendment will be filed at the time of final design for major <br />stages of the gas control system. <br />VI.B.3. Monitoring <br />VI.B.3.a.

Furthermore, the <br />location, spacing, depths, and number of wells will be <br />discussed. <br />VI.B.3.c. Monitoring Well Logs <br />14 CCR 17783.5(d)(2) <br />An amendment will be filed at the time of final design of each <br />Appendix P <br />phase; this amendment will describe procedures of <br />maintaining a record of each monitoring well. Existing monitor <br />well logs are in Appendix P. <br />VI.B.4. Gas Condensate <br />Pacific Energy, a subcontractor to the City, is responsible for <br />Collection System <br />gas condensate at the existing landfill. They currently store <br />and burn the condensate. An amendment will be file at the <br />time of final design of the gas collection system to describe <br />the gas condensate collection system <br />
