Date: Thu, 19 May 2005 09:52:40 -0700 Subject: chrome From: mhicks@ARB.ca.gov Staff of the Air Resources Board will be conducting a source test at Clovis Specialty Plating located in Fresno, California, the week of May 23, 2005. The purpose of this test is to determine the hexavalent chromium emission rate at a decorative chromium plating operation, using a freshly prepared plating bath containing low levels of metallic contaminants. The results of this test will be compared to those of a test conducted with a plating bath containing significant amounts of metallic contaminants. The protocol to be used to conduct the test is essentially the same as the protocol found at the following web address: http://www.arb.ca.gov/toxics/chrome/testing.doc ====================================================================== You are subscribed to the chrome mailing list.

This test is third in a series of tests evaluating the effect of contaminant levels on emission rate. As you know, these tests are being conducted at decorative chromium plating facilities without forced ventilation systems. The protocol for this source test is essentially the same as previous source tests done for phase II of the testing program in Sacramento in 2004. The reports of the Sacramento tests are available on our web site at: http://www.arb.ca.gov/toxics/chrome/etest.htm The ARB test team has already conducted two source tests at a facility in Fresno, CA. The first test was conducted on the decorative chromium plating tank in October of 2004. This source test measured chromium emissions off the tank with contaminant levels over 15,000 ppm or over 2 oz/gal. These contaminants include; Trivalent chromium, Iron, Nickel, Copper, Chloride, and Zinc. The second test was conducted in May of 2005. This source test measured chromium emissions off a clean decorative chromium plating bath at the same facility. A new solution was made which had the above contaminants at <1000 ppm or <0.13 oz/gal. The third source test is scheduled for later this month. A portion of the old chromium plating bath was saved from the first test. This bath will be added to the new bath, as well as some chemicals to increase the contaminant levels. We are recommending the following contaminant levels for the next test and would like to get your comments. The overall contaminant levels for the next test would be <4,500 ppm or <0.60 oz/gal. The breakdown of the contaminants would be as follows: Trivalent chromium – 2,300 ppm Iron – 1000 ppm Nickel – 500 ppm Copper – 500 ppm Chloride - < 20 ppm Zinc - < 20 ppm Please contact Shobna Sahni with comments on the proposed contaminant levels by June 24th, 2005 at (626) 575-7039 or spandhoh@arb.ca.gov. ====================================================================== You are subscribed to the chrome mailing list.
