z PLAINTIFF'S EXHIBIT / EXX--- S Baton Bougs, Lowlelsna Petroleum Products Laboratory Msvasfcsr 19, 1953 On October 8, 1952 a teat mu started to determine the dost fell in the refinery* The looation selected for the first test mu on the roof of the P*T*8* office baUding and the test mas conducted over a 30 day period (October 8 - lovenber 6, 1952)* Paring this period there mu no rain with an average high teaperatnre of 78*0*F* and an average low of 46*3*F. The wind mu north and northeast 18 days with an average velocity of 8*8 miles per hoar* The remainder of the period had sooth and southeast winds with an avenge velocity of 3*8 miles per hoar* Unfortunately the wind directions were each that FCLi Catalyst fall was not included to any extent in the test, however, the 18 days of north and northeast wind should have shown much of the fall from the Industries north of the refinery* The data obtained are tabulated below* Ton/So* lHiaflfwith Total solids Mater insoluble solids Wiatsr soluble solids 35*2. 24*7 10.5 Composition of Mater Soluble Solidsi Organic Matter (Volatile) Positive ions identified Vegativa ions identified 6.2 Sodium, Aanonia, fnH Inn Sulfate and Silieats The water insoluble solids contained 18*9 tans/Sq. Kile/noath of volatile matter* This mu due in large part to soot particles* The only figoree available for comparison were obtained at the Baltimore Refinery February and March 1952* These Indicated 40 to 50 tons/Sq. Xile/nenth total dost fall in the industrial area and 40 to 78 tons inside the refinery* ' cci PAXfitBIHtMBAsFSTiHBiKHsttHeAtHnr 03620
