ENGINEER: Choudhary \ AG PV (kg/yr): 315,000 YX

SUBMITTER: TTM Technologies, Inc.
USE: The PMN material in waste etching solutions will be chemically reacted to form other copper compounds, specifically copper oxide and other copper chemicals (50%) and atacamite (Cu2Cl(OH)3, CASRN 1332-65-6) which is used in the production of animal feed micronutrients (50%). To form copper oxide precipitates, the PMN material will be reacted with caustic soda with heating. To form atacamite, the PMN material will be reacted with hydrochloric acid and water or an aqueous solution of acidic cupric chloride. P2REC: CRSS: Forward. P2 Claim: The recycling of the PMN material can eliminate potential environmental releases to landfills of copper compounds. Files 152:551073 CA, 105:27627 CA, 150:285763 CA, and 133: 152663 CA are for the use of the PMN material in wastewater as a chemical intermediate for the manufacture of copper oxide.

OCCUPATIONAL EXPOSURE RATING: 1B

NOTES & KEY ASSUMPTIONS: Generated by the 06/07/2005 version of ChemSTEER.

POLLUTION PREVENTION CONSIDERATIONS: P2 Claim: The PMN substance is the result of a research project to develop a process to reclaim the copper from byproducts of the manufacturing of printed circuit boards. The project resulted in the development of dicopper chloride trihydroxide crystals. Because of their neutrality, insolubility in water and high copper content, these crystals were studied as a potential source of nutritional copper in animal diets. A proprietary process has been refined for using two types of spent etching solutions (material used in manufacturing electronic printed wiring boards). These spent etchants can be reacted to produce a copper crystal matching the desired basic copper chloride formula. As a result, the spent etchants from printed wiring boards that were once considered waste could now be recycled to make tracefile:///J|/INITENG/P12%20cases/p120285.eng.txt[7/2/2012 8:03:40 AM]

Number of Sites/ Location: 6 Chippewa Falls Chippewa Falls WI 54729 Stafford Stafford CT 06075 Logan Logan UT 84321 San Diego San Diego CA 92111 Santa Ana Santa Ana CA 92704 Santa Clara Santa Clara CA 95050 Days/yr: 350 Basis: Submission provides PV of 315,000 kg/yr and 6 MFG sites. The manufacture of the PMN is as a byproduct in spent etchant solution from the etching of printed wiring boards, and the PMN is at 40% in liquid at each site. Submission provides throughput of each site, which ranges from 25 to 275 kg/site-day, and the operating days per year are either 250 or 350 for each site. As process description, worker activities, and releases are the same or similar for all sites, all 6 sites are combined into a single operation and average mass balance parameters are used. CEB assesses 6 sites and 350 days/year (more conservative for release frequency), and ChemSTEER calculates an average throughput of 150 kg/site-day PMN. Submission estimated 0.1 kg/site-day release for each site independent of throughput; therefore, assessing all 6 sites identically using 350 day/year presents a more conservative assessment for 250 day/yr sites.

### circuit board manufacturing facility has an on-site wastewater treatment (WWT) system for metals removal from both rinse waters and spent baths. These treatment systems are the traditional pH adjustment using sodium hydroxide to a nominal pH 8-9 range, acceptable for discharge under permit pursuant to the local pretreatment program to the municipal POTW (Publicly Owned Treatment Works). In addition to pH adjustment, a chelate breaking reagent such as DTC (sodium dimethyl dithiocarbamate) or polysulfide is used to precipitate the chelated copper in the tetraamine copper dichloride (TACD) and other chelated copper sources. Precipitated copper and other precipitated metals are classified as a F006 listed waste, and are then removed via traditional filter press for beneficial recycling of the metals contained in the WWT sludge. Treated wastewater is monitored in strict accordance with the POTW and monitoring results are reported on a monthly or quarterly basis as required by each permit.

Water Output 2: 1.0E-1 kg/site-day over 350 days/yr from 6 sites to: On-site Wastewater Treatment (submission) from: Cascade Spray Rinse Station basis: User-Defined Loss Rate Model. Submission estimates a release of 0.1 kg/site-day (or less) from the cascade spray rinse of the etched panels. Release is independent of PMN throughput. Submission states release is to on-site wastewater treatment. Submission does not mention discharge from on-site WWT system. CEB assesses 0.1 kg/site-day over 350 days/year (high-end of operating days per year of the 6 sites).
