Scottsdale Road Scottsdale, Arizona 85254 Dear Ron: This letter is in response to your request for information on the lead and arsenic content of Vista*s detergent alkylate. Vista does not routinely analyze for these metals. However, in December a special analysis was run on Nalkylene 500 product. The results indicated no detectable levels of lead (detection limit 0.1 mg/1) or arsenic (detection limit 0.01 mg/1). Further, there is no identifiable source of these metals in the feedstocks or process used for production of our Nalkylene products. Sincerely, Thomas G. Grumbles Environmental Quality Manager bh cc: Mike Cox Carl Kerfoot VVV 000010102
