Franzen-Hill <br /> System Design,Construction 8,Maintenance <br /> April 22, 1992 <br /> PG&E <br /> Attn: Mike Savage <br /> 650 "O" Street <br /> Fresno, CA. 93715 <br /> Re: Stockton <br /> Dear Mike, <br /> After measuring our piping runs and calculating the total fuel that <br /> each run would hold using the 3" glass dimensions. <br /> The unleaded line will hold 36.4 gallons and the diesel line will <br /> hold 28 .4 gallons. Presently our diesel piping sump will hold 8" <br /> of liquid which calculates out to 55. 1 gallons of fluid. The <br /> unleaded piping sump will hold at 13" which calculates out at 84 . 9 <br /> gallons. <br /> As you can plainly see the unleaded sump will contain more than <br /> 200% the capacity of the line and the diesel sump will also hold <br /> approximately 200% of the diesel liquid capacity. Since it only <br /> takes 2 quarts of liquid in either piping sump to set off the <br /> liquid sensor and shut the turbines down, it does not seem <br /> extremely logical to require the sumps to contain more liquid that <br /> has been presently demonstrated. <br /> If you have any questions please do not hesitate to contact me. <br /> Respectfully, <br /> Tom Lockwood <br /> TL/kt <br /> 1100 North J Street,Tulare,California 93274/209-688-2977/800-655-3436/209-688-1467 FAX <br />
