The flow rate will be measured by direct measurement where sufficient flow rates exist <br />and by visual estimation where direct measurement is not practical due to low flow or an obstructed <br />source. A feature having a flow rate of less than 1 gpm will be designated a seep. A feature with <br />a flow rate of greater than or equal to 1 gpm will be designated a spring. <br />The springs and seeps will be monitored on a twice per yeaz basis, in the spring and fall of <br />each yeaz, corresponding to high flow and low flow conditions, during the baseline monitoring <br />period and during commercial operations. During the baseline monitoring period, the flow rate will <br />be measured, and features having sufficient flow and access will be sampled for the water quality <br />parameters listed in WQ2 (Table 3). The water quality samples will be collected according to <br />procedures detailed in Appendix C. After the baseline period, only field parameters (pH, <br />temperature, conductivity) will be collected. The occurrence of springs and seeps that were not <br />documented in the baseline surveys will be documented during subsequent surveys. <br />4.4 Rainfall Monitorieg <br />A rain gauge will be located at the Yankee Gulch Lease site. The rain gauge will be located <br />clear of overhead obstruction. It will be monitored daily and the amount of precipitation recorded <br />monthly along with date, time, and other pertinent information. <br />' S.0 PROCESS MONITORING <br />The solution mine process plant, solution mining wells, and associated plumbing will be <br />1 <br /> <br /> <br />1 <br />1 <br />1 <br />1 <br />monitored according to the schedule and criteria presented in this section. All process monitoring <br />data will be included in monitoring reports that will be submitted monthly to the BLM. Details of <br />the process monitoring schedule and criteria aze presented in Table 4. <br />5.1 Solution Wells <br />Solution mining wells will be monitored for pressure, temperature, mass flow rate, fluid flow <br />rate, and density of inflow and outflow at 10-minute intervals. The data will be recorded at 10- <br />minute intervals and reported to a central control system. <br />Monitoring systems will be in place at the solution well trunk line (upstream of the steam <br />stripper) prior to raising average cavity temperatures above 300°F to provide baseline data for carbon <br />Agapito Associates, Inc. <br />
