Page 17 SANITIZED SUBMISSIONThe PMN substance (CAS# 22288-41-4) will be used as a highly reactive polymerization initiator at a level of 300-400 ppm in the production of

polyvinylchloride (PVC). The existing substance (CAS# 26748-38-9) currently being used for this PVC application is being phased out of production gobally due to a lack of availability of a key raw material. The choice to use the PMN substance as the suitable replacement for the existing substance (CAS# 26748-38-9) is expected to reduce the overal risk to human health and the environment. The PMN substance has a vapor pressure of 300 Pa @ 20 degrees C. (see ATTACHMENT 16) that should result in a lower potential for inhalation of vapors by workers. Second, the PMN substance is thermally and more hydrolytically unstable; the PMN substance will more quickly decompose in water, especially at temperatures in excess of its SADT, decreasing the potential for adverse effects on aquatic organisms. The PMN substance is readily biodegradable and is not expected to bioaccumulate, whereas the existing substance is predicted not to be readily biodegradable (ECOSAR). The PMN substance is less water soluble than the existing substance and would be less available to aquatic organisms within the living zones of water bodies. The acute toxicity to algae of the PMN substance (~2.5 mg/L)(see ATTACHMENT) is only moderate, whereas the existing substance is estimated to be highly acutely toxic to algae (0.198 mg/L; ECOSAR). Finally, the burn rate of the PMN substance (13.5 kg/min m2) is substantially less than the burn rate for the existing substance CAS# 26748-38-9 (37.15 kg/min m2), decreasing the potential for serious fires. Therefore based upon all of the information presented above, the use of the PMN substance to replace the existing substance should result in a lower risk to human health and the environment. A comparison of the pertinent chemical and physical properties is as follows: PROPERTY PMN SUBSTANCE* EXISTING SUBSTANCE** Log Kow 4.9 3.78 H20 solubility < 0.6 mg/L 25.2 mg/L Vapor pressure 300 Pa@20 C. 27 Pa@ 25 C. * Measured data points, see ATTACHMENTS ** Estimated data points from US EPA EPISUITE/ECOSAR software models
