Multiple machine processes were observed in both shops, samples were <br /> reviewed from machines and sizes were compared to an approximation size of 100 microns(less than the point of a <br /> strand of hair).All metal fines generated were of large visible sizes that were determined larger than 100 microns <br /> and did not meet the definition of a"dust". <br /> #301 Daily sweeping will occur within each section of the machine and grinding shops to ensure proper waste <br /> categorization of any contaminated materials and the prevention of any metal generated shavings to be released to <br /> the environment.Spills will be immediately cleaned up with the proper waste characterization of any absorbent <br /> material utilized,facility personnel will receive training on proper spill response monthly. <br /> Thank you, <br /> Kara <br /> From: Baker, Lydia <Ibaker@sjgov.org> <br /> Sent:Tuesday, December 24, 2019 1:41 PM <br /> To: Kara Kardashian <karak@cozad.net> <br /> Cc:Tom Pistacchio<TomP@cozad.net> <br /> Subject: RE: Return to Compliance <br /> Hello Kara, <br /> I reviewed the results that you sent over. To close out the last two open violations this is what I still need: <br /> -#102-What did you do with the bucket that was overflowing in the machine shop? Is that a waste or something that <br /> can be used? For the metal fines, how did you determine that they were larger than 100 microns? <br /> -#301-How did you fix this violation? You can just email me what you did. <br /> If you have any questions please let me know. Have a Merry Christmas! <br /> Best Regards, <br /> Lydia Baker <br /> i <br />
