Box 806 <br /> Sacramento, 95812-0806 <br /> Dear: Mr. Sullivan: <br /> This letter is being sent to provide you with the opinion of our technical expert in response to i <br /> your February 16, 2016, inquiry requesting our Board's opinion as to whether a Tank <br /> Assessment Report for Tank Number 57 at the Evoqua Water Technologies Site submitted to the <br /> Department of Toxic Substances Control by Omega Technical Services would be required to <br /> prepared, stamped, and signed by or under the responsible charge of a California licensed civil <br /> engineer. As you were advised, the report and all of the attachments provided in your February <br /> email were sent to a technical consultant for review. The consultant provided an opinion which <br /> concluded that the report contained elements that would be required to be prepared, stamped, and <br /> signed by or under the responsible charge of a licensed civil engineer. <br /> His review and subsequent opinion was as follows: <br /> On October 5, 2015, Omega Technical Services submitted a Tank Assessment Report for <br /> Tank Number 56 at the Evoqua Water Technologies site at 5375 South Boyle Avenue, <br /> Los Angeles, California. Since the tank and its associated system handle and contain <br /> hazardous waste regulated by the State of California, Evoqua was required to perform a <br /> tank assessment pursuant to 22 CCR § 66265.192, 22 CCR § 66264.191, and associated <br /> state regulations. An earlier tank assessment report, dated 5-27-14, for Tank Number 1 at <br /> the same facility, was also submitted and is a part of the current case record. It is not the <br /> substance of the tank reports, but rather the required professional licensure of the person <br /> certifying the Tank Assessment reports that is at issue. <br /> California Code of Regulations Title 22 Section 66264.191 (22 CCR § 66264.191), <br /> Assessment of Existing Tank System's Integrity, requires that tanks be inspected, among <br /> other things, to determine that the tank systems have sufficient structural strength...to <br /> ensure that they will not collapse, rupture or fail. This includes the foundation, structural <br /> support, and seismic considerations. These latter include consideration of the soil <br /> underlying the tank foundation, the structure foundation itself, and connections of the <br /> structure to the foundation. Certification of secondary containment requires hydrographic <br /> analysis to determine capacity if stormwater can enter the secondary containment. If the <br /> secondary containment were a stationary building structure, its structural adequacy would <br /> also require certification. The results from a leak test, an internal inspection, and a dye <br />
