On 29 July 2014 Water Board staff <br /> inspected the facility in preparation of Musco constructing two new Class II surface <br /> impoundments, Pond C and Pond D. As shown in the Photo Log (enclosed), staff also <br /> inspected the existing Class II surface impoundments, Pond A and Pond B. <br /> Staff met with Mr. Dennis Leikem of Musco, and the consultant to Musco, Mr. Andrew Romolo <br /> of Terraphase Engineering. The weather on 29 July 2014 was clear and warm, with a slight <br /> breeze from the southwest. Staff met with Musco personnel at the existing Class II surface <br /> impoundments to inspect the ponds for freeboard levels and general maintenance of the levees <br /> and berms. Staff observed that Pond A was near full and that plant discharge was being <br /> directed to Pond A. As shown in Photo 3, staff inspected Lysimeter 18, which has been <br /> reported as having elevated specific conductance in water collected from the lysimeter. The <br /> lysimeters are part of the unsaturated zone monitoring of the Detection Monitoring Program for <br /> the Class II surface impoundments. <br /> Staff inspected Pond B, which had water levels approximately two feet below that of Pond A. <br /> Plant discharge was not being directed to Pond B during this inspection and evaporation was <br /> keeping liquid levels low in this pond. Staff inspected Pond B northern sump, which contained <br /> liquid. It also appeared the sump had recently discharged into the pond. Liquid in the sump <br /> indicates the primary liner is leaking. The levees or pond berms had recently been dragged and <br /> were free of vegetative growth and no channeling or erosion rills were observed. <br /> Staff inspected the ongoing construction of Pond C and Pond D. These ponds are being <br /> constructed to add capacity to the Musco facility and to replace Pond A. Both Pond C and Pond <br /> D were shaped and berms were being constructed during this inspection. The contractor was <br /> excavating, moisture conditioning the soil, and compacting, as shown in the Photo Log. The <br /> floor of Pond C was near finish elevation including berms heights. Staff inspected the field daily <br /> sheets with the construction quality assurance (CQA) monitor and discussed the CQA report. <br /> During the inspection of the construction site, it appeared the earth moving and pond <br /> construction was on schedule. Excavation of sumps and installation of liner material is <br /> scheduled for second week in August 2014. <br /> CIWQS SIID#17226055 <br /> KARL E. LONGLEY ScD, P.E., CHAIR I PAMELA C.
