Attachment H <br /> Operating Data <br /> Application Requirements <br /> Submit the following proposed operating data for each well (including all those to be <br /> covered by area permits): (1) average and maximum daily rate and volume of the fluids to <br /> be injected; (2) average and maximum injection pressure; (3) nature of annulus fluid; (4) for <br /> Class I wells,source and analysis of the chemical,physical,radiological,and biological <br /> characteristics,including density and corrosiveness, of injection fluids; (5) for Class 1I wells, <br /> source and analysis of the physical and chemical characteristics of the injection fluid; (6) for <br /> Class III wells, a qualitative analysis and ranges in concentrations of all constituents of <br /> injected fluids. If the information is proprietary,maximum concentrations only may be <br /> submitted,but all records must be retained. <br /> Approach <br /> Although the STIG-1 and LEC-1 wells will have similar construction, they will be operated <br /> differently and will inject different quality water because they support plants that use <br /> different processes and operate differently. Additionally,there are routine operating data <br /> for the STIG-1 well from 2000. Therefore,each of the required items will discuss STIG-1 and <br /> LEC-1 separately. <br /> The LEC-2 well,if drilled,will operate as a backup well to the two plant wells. It could take <br /> water either from waste lines or from the waste holding tanks at each plant. <br /> Injection Rates and Volumes <br /> The average and maximum daily rate and volume of the fluids to be injected is presented in <br /> this section. <br /> STIG-1 <br /> The STIG-1 well has been operated routinely since 2000. Because the STIG facility supplies <br /> electricity when supplemental power is needed during periods of high demand,operation <br /> of the injection well varies. For example, during the California energy crisis of 2000-2001,the <br /> plant operated at nearly full capacity. Since then,however,the plant operates during <br /> periods of high electrical system demand with pre-scheduled maintenance shut-downs, <br /> primarily during the off-peak months. <br /> During plant operation,water to be injected is stored in the onsite 60,000 gallon holding <br /> tank until there is a sufficient volume of water for injection.When the plant is operating, <br /> injections at STIG-1 have occurred between 1 and 22 days per month with the remainder of <br /> the wastewater returned to the WPCF,in accordance with the agreement with the City <br /> SAC/371322/082550024(ATTACHMENT-H.DOC) H-1 <br />
