GENERAL INSTRUCTIONS 

• You must provide all information requested in this form to the extent that it is known to or reasonably ascertainable by you. Make reasonable estimates if you do not have actual data. 

• Before you complete this form, you should read the “Instructions Manual for Premanufacture Notification” (the Instructions Manual is available from the Toxic Substances Control Act 

 (TSCA) Information Service by calling 202-554-1404, or faxing 202-554-5603). 

• If a user fee has been remitted for this notice (40 CFR 700.45), indicate in the boxes above the TS-user fee identification number you have generated. Remember, your user fee ID number 

 must also appear on your corresponding fee remittance. For mailing address information see the Help instructions in the e-PMN tool.

Part I – GENERAL INFORMATION 

You must provide the currently correct Chemical Abstracts (CA) 

Name of the new chemical substance, even if you claim the 

identity as confidential. You may authorize another person to 

submit chemical identity information for you, but your submission 

will not be complete and the review will not begin until EPA 

receives this information. A letter in support of your submission 

should reference your TS user fee identification number. For all 

Section 5 Notice submissions (paper or electronic) you must 

submit an original notice including all test data; if you claimed any 

information as confidential, an original sanitized copy must also be 

submitted. 

TEST DATA AND OTHER DATA 

You are required to submit all test data in your possession or control and to provide a 

description of all other data known to or reasonably ascertainable by you, if these data are 

related to the health and environmental effects on the manufacture, processing, distribution in 

commerce, use, or disposal of the new chemical substance. Standard literature citations may 

be submitted for data in the open scientific literature. Complete test data (written in English), 

not summaries of data, must be submitted if they do not appear in the open literature. You 

should clearly identify whether test data is on the substance or on an analog. Also, the 

chemical composition of the tested material should be characterized. Following are examples 

of test data and other data. Data should be submitted according to the requirements of 

§720.50 of the Premanufacture Notification Rule (40 CFR Part 720).

 LOREX Modification 

OPTIONAL INFORMATION 

You may include any information that you want EPA to consider in 

evaluating the new substance. On page 11 of this form, space has 

been provided for you to describe pollution prevention and 

recycling information you may have regarding the new substance. 

“Binding” boxes are included throughout this form for you to 

indicate your willingness to be bound to certain statements you 

make in this section, such as use, production volume, protective 

equipment . . . The intention is to reduce delays that routinely 

accompany the development of consent orders or Significant New 

Use Rules. Checking a "binding" box in a PMN does not by itself 

prohibit the submitter from later deviating from the information 

(except chemical identity) reported in the form; however, in the 

case of exemption applications (such as TMEA, LVE, LOREX) 

certain information provided in such notifications is binding on the 

submitter when the Agency approves the exemption application, 

especially if the production volume "binding" box is chosen in a 

LVE.

OPTIONAL POLLUTION PREVENTION INFORMATION

To claim information in the following section as confidential, bracket (e.g. {}) the specific information that you claim as confidential. 

In this section you may provide information not reported elsewhere in this form regarding your efforts to reduce or minimize potential risks 

associated with activities surrounding manufacturing, processing, use and disposal of the PMN substance. Please include new information 

pertinent to pollution prevention, including source reduction, recycling activities and safer processes or products available due to the new chemical 

substance. Source reduction includes the reduction in the amount or toxicity of chemical wastes by technological modification, process and 

procedure modification, product reformulation, and/or raw materials substitution. Recycling refers to the reclamation of useful chemical components 

from wastes that would otherwise be treated or released as air emissions or water discharges, or land disposal. Quantitative or qualitative 

descriptions of pollution prevention, source reduction and recycling should emphasize potential risk reduction in addition to compliance with existing 

regulatory requirements. The EPA is interested in the information to assess overall net reductions in toxicity or environmental releases and 

exposures, not the shifting of risks to other media (e.g., air to water) or nonenvironmental areas (e.g., occupational or consumer exposure). To the 

extent known, information about the technology being replaced will assist EPA in its relative risk determination. In addition, information on the 

relative cost or performance characteristics of the PMN substance to potential alternatives may be provided. 

Describe the expected net benefits, such as 

(1) an overall reduction in risk to human health or the environment; 

(2) a reduction in the generation of waste materials through recycling, source reduction or other means; 

(3) a reduction in the use of hazardous starting materials, reagents, or feedstocks; 

(4) a reduction in potential toxicity, human exposure and/or environmental release; or 

(5) the extent to which the new chemical substance may be a substitute for an existing substance that poses a greater overall risk to human 

health or the environment.

Information provided in this section will be taken into consideration during the review of this substance. See PMN Instructions Manual 

and Pollution Prevention Guidance manual for guidance and examples.

 Enter Attachment filename for Pollution Prevention Page 11.

PMN2013P11

The 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.
