OLIN MESA CORPORATION' <br /> This facility discharges process wastewaters through a elementary neutralization unit for PH adjustment <br /> only Prior to the elementary neutralization unit, an in-process copper removal unit electroplates:collects <br /> metallic copper from one particular wastewater system. All facility process wastewater is discharged under <br /> permit to the San Jose/Santa Clara Water Pollution Control Plant This facility has been cited by the Santa <br /> Clara County Department of Public Health for operating this way without a permit or a variance. <br /> In speaking with NIr Tim Dunn of the CADOHS-Emoryville Office, he informed me that your office is in the <br /> process of amending Title 22 to provide these type operations permit-by-rule Also. CADOHS has requested <br /> that facilities not submit variance applications and those facilities with variance applications pending were <br /> on-hold for review <br /> Could you please confirm to me in writing that the situation that I have described for Olin s two facilities is <br /> the correct CADOHS position at this time. Also, I would like to be copied on any draft,'amended regulations <br /> regarding elementary neutralization unit operations for my review and comment <br /> � <br /> Thant You. <br /> vT` A1qZ7t9_"e <br /> W D Mitchell <br /> Assoc.Env Affairs Specialist <br /> cc G M.
