Subject | Pollution Controls Work! They stop hexavalent chrome in its tracks. |
Comment | Hello CARB Members: I wanted to send you proof of the effectiveness of source controls when it comes to hexavalent chromium emissions. I have attached the Excel version to make it easy for your team to check formulas. The South Coast AQMD monitored our facility fence line to fence line for 9 months. The attached data was pulled from their website. The fence line monitors where within 20 feet of our buildings, and our chromic acid anodize tank and spray booths were directly in between, as the prevailing winds blow. And the winds off of the ocean are fairly predictable. EME, Inc. was one of the first, if not the first, to place pollution controls on our chromic acid tank. That tank and the paint booths are fitted with HEPA filtration. Note that the difference between the monitors is 0.00 nanograms when the one significantly test result is thrown out (it is less than a quarter of a nanogram even with that anomaly). The fact that there are low amounts of hexavalent chromium in the monitors at most times is because the Alameda Train Corridor and Alameda Ave (a large thoroughfare) are just downwind from our facility. Bans are not the way to go! When it comes to hexavalent chromium, source controls have done the job effectively for years. Best regards, Wesley Turnbow E. M. E., Inc. 431 E.
