PMN: 03-0141

USE #1:

Site/Location: <1,000 unknown sites (per contact report) Days/yr: 220 (per submission) basis: .

Process Description: PMN substance imported in stainlesssteel containers ->Loaded into holding tanks -> Reaction process for 2 days -> PMN not incorporated with final product is separated out and purified for use

ENVIRONMENTAL RELEASES (Eqpt. cleaning, container residue, etc.): WATER: 0.018 kg/site-day over 50 Days/year from: Equipment cleaning to: on-site WWT (submission) basis:

AIR: Negligible (<23.26 kg/site-yr) from: fugitive emissions from emptying drums to: Stack air basis:INITIAL REVIEW ENGINEERING REPORT

PMN: 03-0141

USE #1: CONT.

INCINERATION: < PV from: Equipment cleaning, spent solvent, and container residue. basis:

LANDFILL: Not expected Basis:

OCCUPATIONAL EXPOSURE Tot. # of workers: 1000's (CEB minimum of 3 workers per site) Days/yr: 220 (submission)

Inhalation: Vapor (class II) Worst: 8 mg/day over 220 Days/yr Typical: 0.3 mg/day over 220 Days/yr

Number of workers with inhalation exposure: <1000's Basis: Used CEB spreadsheet for vapor generation and inhalation exposure. The reaction takes place in a closed system; however, inhalation exposure during loading to the holding tank may occur. Assumed a 1 inch bung to estimate open surface emissions during unloading. These results are saved in P01141.wk1. Assumed 0.05 hours per day operation (to unload 50,000/1,000/220=0.23 kg)

Note: The respirator class: II. Gas/vapor (all substances in the gas form);

Dermal: contact with liquids: 1,800 mg/day 100% concentration Basis: CEB Routine Contact, 2 hands (Cleaning of equipment) 1005 * 1,800 mg/dayINITIAL REVIEW ENGINEERING REPORT

USE #2:

Site/Location: 4 unknown use sites (generic scenario) Days/yr: 250 (standard CEB estimate) Basis:

Process Description: Polymers dissolved in the PMN substance may be coated on the surface of semiconductor parts. The PMN substance may be evaporated to leave a polymer layer on the surface (submission)

ENVIRONMENTAL RELEASES (Eqpt. cleaning, container residue, etc.):
