Specifically, <br /> you reference CCR 662612.11 Failed to detemune if a waste is a hazardous waste. Your note reads in salient part: <br /> "Notice of Violation, Class ll:#7 Failed to determine if a waste is a hazardous waste, Facility <br /> generates metal shavingsfrom brake rotor lathe operations. Metal waste that is>I00 microns in <br /> size can be sent to, metal recycler. Title 22 listed metal waste that is<100 microns in size must be <br /> handled and dispo ed of as hazardous waste. Facility could not provide hazardous waste manifests <br /> for metal dust less than,:100 microns in size(Title 22 listed metals). <br /> Make a hazardous'waste determination on the brake rotor lathe shavings as specified in Title 22 <br /> California code of Reguladons or handle as hazardous waste. Correct by 3-26-10. Send copies of <br /> scrap metal recyeli g receipts for the last two pick-ups of scrap metal to the environmental Health <br /> Department(EHD by,3-26-10. <br /> "Summary of vwju-#7 Class rr <br /> "Notes: # )' Fill put and return the following by 3-26-10: <br /> > Return to Compliance Certification Forme <br /> > A corrective action statement for each violation <br /> > Supporting documentation <br /> Facility generated 5.7 tons of HW in 2008 and 8.5 tons HW in 2009" <br /> However,AT&T assens at i has complied wi[h that requirement because generator knowledge is sufficient to <br /> determine that the waste ' question is not a hazardous waste.The waste in question consists of metal shavings <br /> from vehicle brake maint nance work,Most of these shavings are scrap metal,which is conditiotially excluded <br /> from the definition of h dous waste(see 22 Calif. Code of Regulations Section 66260.10). Of the six <br /> exclusions from the defn tion.of"scrap metal,"only one is relevant here:the exclusion of"Sludge,fine <br /> powders, semi-solids and liquids`that are hazardous wastes <br /> "Fine powder"is defined�s "a metal in dry,solid form having a particle size smaller than 100 micrometers <br /> (0.004 inches)or micronslin diameter".The brake shaving waste in question includes some particles of less than <br /> l00 micron-,(about 0.08%of the total waste,by weight; see Attachment 1). However,under California law, such <br /> particles are not automatiq.Jly,hazardous waste, Rather,they are hazardous waste only if they are a listed <br /> hazardous waste metal,w 'ch these are not,or if they exhibit a hazardous waste characteristic. <br />
