Tait Environmental Systems has <br />b asked to perform additional repairs to components that failed the previous SB -989 testing. The Failed <br />comp nts we have been asked to repair are as follows- Dispenser pans 3-4, 5-6, 7-8 and the 89 -turbine <br />sump- J from the information I have gather from the testing technicians and previous repair crew I <br />have formu d the following scope of work. Prior to any work all -electrical to the dispensers and turbine <br />sumps will be t down by our electrician who will remain on site for the duration of repairs to <br />troubleshoot any lems that may arise during the repairs. Each one of the dispensers will be removed to <br />gain access to the dis ser pans so each one of the penetrations in the dispenser pans can be removed and <br />replaced with a Blueline split UL approved penetration fitting. To do so we will remove the shear <br />valves and install a tempor cap on the end of the flex hose during repairs to prevent any potential <br />spillage and vapor leaks in the ' penser pans. Upon installation of the penetrations we will also install <br />secondary reducer test boots on a e secondary to primary piping in the dispenser pans pre-test each <br />component and reinstall the dispens After all work has been performed in the dispenser pans the repair <br />crew will commence work in the 89 tur sump they will thoroughly clean and prep the sump to collar <br />connection and apply a layer of fiberglass ' g around the collar seam to remedy the potential leak <br />point. The tank is a manufactured by Owens Co ' they recommend if the tank itself in the sump is to be <br />repaired or modified in any fashion it must be done ertified party. Due to the scope of work we are <br />performing we will be glassing the sump to collar an IC ller/retro-fit certified installer may perform <br />the repairs. <br />I have enclosed various cut sheets for the components we will be install s well as the various required <br />certifications of the repair crew. We anticipate these repairs to be completed n a one week period and <br />will be performed under direct contact with either yourself or another designate ncy representative. <br />Thank you, <br />Tait Env�onmenta ystems <br />CA Lic #588098 - AZ Lic #095984 • NV Lic #0049666 <br />1863 North Neville Street - Orange, California 92865 • 714.560.8222 - 714.685.0006 Fax <br />11280 Trade Center Drive - Rancho Cordova, California 95742 - 916.858.1090 - 916.858.1011 Fax <br />www.SB989.com <br />
