T. Bird, GCC Energy, LLC 31 Dec 2014 <br />C- 1981 -035 / Annual Pond Inspection Review Page 2 of 2 <br />(c) The depth and elevation of any impounded waters at the time of the certified report; <br />(d) Existing storage capacity of the impoundment; and <br />(e) Any other aspects of the structure affecting stability, or requiring maintenance. <br />The 2014 report by Stoner fulfills the majority of the requirements described above. However, <br />certain information has not been provided. <br />Stoner's report indicates that approximately 8 inches of water were present in the pond, <br />but does not give an elevation for the water surface (15)(c). Please provide the elevation <br />of the water surface that was present at the time of the inspection. <br />2. The report fails to address the requirements of (15)(d). This volume can generally be <br />readily determined from the storage capacity curve developed for a pond's as -built plan. <br />Please provide the storage capacity of the pond that was present at the time of the <br />inspection. <br />Please submit the required information by January 30, 2015. <br />If you have any questions or need additional information, please contact me. <br />Sincerely, <br />Marcia L. Talvitie, P.E. <br />Environmental Protection Specialist <br />
