Prior to tank lining, a site assessment must be performed under the direction of Public Health Services <br />Environmental Health Division (PHS-EHD), site mitigation unit. <br />Site Assessment has been performed under PHS-EHD direction <br />Site Assessment has not been performed under PHS-EHD direction. Please contact PHS-EHD <br />site mitigation unit at (209) 468-3450 for information regarding the assessment requirements. <br />2. Reason tanks will be interior lined/repaired: <br />Meet State/Federal upgrade requirements (submit PHS-EHD UST upgrade permit application <br />with this application) <br />Tank system failure, <br />3. The following tests are required to be performed prior to lining to determine the structural integrity of the <br />UST: <br />Steel tanks <br />Ultrasound Test (Note: The UST shall be closed in accordance with Article 7 Title 23 CCR if the <br />tank's average metal thickness is less than 75 percent of the original wall thickness of if the tank <br />has any of the listed defects in Article 6, Title 23 CCR section 2663 (b) (2) (B)) <br />Certification by a "Special Inspector that the tank is structurally sound for tank lining and <br />continued use: <br />a. sandblast to white metal <br />_b. count number of holes, splits, perforations, and other defects <br />---c. submit result to EHD <br />Non -steel tanks, fiberglass <br />Certification by a "Special Inspector' that the tank is suitable for lining. <br />_a. interior walls cleaned by wipe down <br />b. interior diameter measurements <br />�c. visual check for structural, tension, or compression problems <br />4. Corrosion protection system <br />Please describe the type of corrosion protection system you propose to install. The cathodic protection <br />system retrofitted on existing UST systems must be designed by a corrosion specialist certified by the <br />National Association of Corrosion Engineers (NAGE) or by a qualified professional engineer. Metal <br />components of the UST system (i.e. submersible pumps, piping etc) that routinely contain fuel and are in <br />contact with the ground must also be cathodically protected. <br />
