Hazardous Waste Tank Assessment January 21.2022 <br /> Central Valle•Waste Seryices Project No. 1246 <br /> Lodi,CA Page 4 <br /> • Tank system is anchored to prevent dislodgement when located within a seismic fault zone <br /> (22 CCR§66265.192(a)(5)(B)): <br /> The governing seismic code is the 2019 California Building Code (CBC).Geographically, <br /> the tank is in Seismic Risk Category III. The tank has six anchors with 3"x3"x'/a" angle <br /> iron set with 518" diameter Hiiti Kwik Bolt 11 expansion anchors with 3-518" embedment. <br /> The system is anchored to prevent dislodgement in the design seismic event. The design of <br /> the anchor clips to conform with the seismic code was previously completed by Mike Smith <br /> Engineering, Inc. in March 2017 (see Attachment Q. There have been no design <br /> changes to the AST since that time. Tim Cook, P.E. of CES inspected the anchors on <br /> January 19, 2022, and determined the installation meets requirements in the seismic code. <br /> • Tank system will withstand effects of frost heave {22 CCR §66265.192(a)(5)(C)): <br /> Site location in Lodi, California is not prone to freezing conditions sufficient to generate <br /> frost heave on structures. The tank is anchored to a reinforced concrete slab. <br /> Certification by the Professional Engineer (22 CCR §66265.192(h)) <br /> I certify under penalty of law that this document and all attachments were prepared under my <br /> direction or supervision in accordance with a system designed to assure that qualified personnel <br /> properly gather and evaluate the information submitted.
