INITIAL REVIEW ENGINEERING REPORT 

PMN: 12-0285

Focus Ready Draft 4/16/2012

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.

OTHER USES: 

MSDS: Yes Label: No

Gen Eqpt: Eye/Face Protection: Wear appropriate eye

protection such as safety glasses and face shield or

splash goggles / Skin Protection: Use chemical resistant

gloves made of suitable material to prevent skin contact.

Chemical resistant clothing is recommended. It should be

impervious to splash and penetration by this product. /

Engineering Controls: Ventilate the work area to avoid

vapor and mist problems. Local exhaust is necessary if

employees will be exposed to airborne levels that exceed

the OSHA exposure limits. Refer to documents such as

"Industrial Ventilation, A Manuafl of Recommended

Practices" by ACGIH.

Respirator: A NIOSH/MSHA-approved respirator is necessary

EPA SANITIZED Page 8 of 49
file:///J|/INITENG/P12%20cases/p120285.eng.txt[7/2/2012 8:03:40 AM]

if a worker may be exposed to airborne contaminant levels

exceeding the exposure limits. Air purifying respirators

must not be worn when there is insufficient oxygen in the

workplace. It is the employer's responsibility to ensure

that the proper respiratory protection is used and that

the worker is properly trained in the use and maintenance

of respirators.

Health Effects: Eye Hazards: This product is strongly

irritating to the eyes. Direct eye contact may cause

discoloring, blurred vision, and severe tissue damage

leading to temporary or permanent injury including

blindness. // Skin Hazards: Causes irritation and burns

to the skin. // Ingestion Hazards: Causes excessive

salivation, nausea, vomiting, and corrosive burning of

the gastrointestinal tract, including performation.

Lesser effects include sore throat, vomiting, metallic

taste, hemorrhagic gastritis, and diarrhea. //

Inhalation Hazards: Corrosive, overexposure causes

burning, irritation, and destruction of the mucous

membranes and upper respiratory tract. Symptoms may

include burning sensation, coughing, wheezing, laryngitis,

 sneezing, mucous production, and sinus congestion. Other

indications of overexposure are headache, nausea,

vomiting, low-grade fever, and shortness of breath.

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 trace

Logan Logan UT 84321

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.
