Kettleman Lane PUBLIC !�.,\t_11" JiGES <br /> Lodi, CA 95242 ENVIRONMENTAL HE,"A-1 I1 DIVISION <br /> Dear Mr. Trevena: <br /> As we discussed earlier, I recently became aware of the fact that the <br /> existing double walled, fiberglass, Owens Corning tanks have what I consider <br /> to be inadequate sumps. They do not allow for inspection and subsequent <br /> monitoring of the space between the top of the tank, inclusive of the bolted <br /> down manhole, and the bottom of the sump. We propose to remove the tank slab <br /> and pea gravel from the top of the tanks and to install the new sump <br /> "collars" directly on the tanks, typical of the current installation <br /> requirements. Owens Corning requires that their own field people install the <br /> new collars in order to maintain the warranty. I have enclosed literature <br /> and a sketch addressing the new sump installation for your review. Owens <br /> Corning has been scheduled to install the new collars during the week of <br /> November 14. <br /> The installation of the new sumps also offers us the ability to update the <br /> "tank trim" to today's standards and we propose to install the following (cut <br /> sheets enclosed): <br /> 6 ea. Teleflex 2"x18" flex connectors <br /> 11 ea. Western fiberglass pipe penetration boot <br /> 12 ea. Western fiberglass conduit penetration boot <br /> 3 ea.
