Pagel of 3 Jeff Wong [EH] From: Jeff Wong [EH] Sent: Wednesday, March 03, 2010 9:11 AM To: 'sahagun, ivo' Subject: RE: Fuel tank Closed- photos and Manifest Unilever Supply Chain Inc Ivo Thanks for writing back. Your effort and committment in environmental responsibility is genuinely appreciated by our Department. BTW, Could you do me a favor and send me photos of the blanked off/ flanged off pipings like we had discussed. The photo you sent me only showed the closed and date marking. One of the conditions for closure is to flange off or blank off all pipings. Also, should not be too relevant to you at this point, but FYI here's the fire codes in the event you guys decide to remove the tank in the future (which may change since new codes are being adopted for 2011): FYI 2007 CA Fire Code Chapter 34 3404.2.14.1 Removal. Removal of above -ground and underground tanks shall be in accordance with all of the following: 1. Flammable and combustible liquids shall be removed from the tank and connected piping. 2. Piping at tank openings that is not to be used further shall be disconnected. 3. Piping shall be removed from the ground. Exception: Piping is allowed to be abandoned in place where the fire code official determines that removal is not practical. Abandoned piping shall be capped and safeguarded as required by the fire code official. 4. Tank openings shall be capped or plugged, leaving a 0.125 -inch to'/4-inch-diameter (3.2 mm to 6.4 mm) opening for pressure equalization. 5. Tanks shall be purged of vapor and inerted prior to removal. 6. All exterior above -grade fill and vent piping shall be permanently removed. Exception: Piping associated with bulk plants, terminal facilities and refineries. 3404.2.14.2 Disposal. Tanks shall be disposed of in accordance with federal, state and local regulations. 3/3/2010
