Help Desk at helpdesk@epacdx.net or call 1-888-890-1995 between the hours of 8am – 6pm 

EST. 

2.2 Installation 

There are two methods for installing the eTSCA/e-PMN software. The Web Start installation 

option can be accessed and downloaded via two CDX internet sites. The version of the 

eTSCA/e-PMN software with encryption requires a CDX login, whereas the version of the 

software without encryption can be accessed at https://cdx.epa.gov/ssl/cdx/eTSCADownloadLiteClient.asp. The InstallAnywhere version runs off a CD and may be more suitable 

for users without an internet connection. 

2.2.1 Web Start Installation (with encryption) 

To download the eTSCA/e-PMN reporting software from the CDX website, log in normally to 

http://cdx.epa.gov. The installation files can be retrieved from the “TSCA: eTSCA Client 

Download” link located on the user’s MyCDX page [Figure 2-1]. This link will only appear if 

the user has registered and been approved under the TSCA Program. 
eTSCA CDX Registration Guide Getting Started 

December 28, 2009 8 

Figure 2-1 MyCDX Page / Link to eTSCA/e-PMN software download 

The page seen in Figure 2-2 contains a link to the install file for the eTSCA/e-PMN software. 

There are two (2) versions of the software: a full version and a lite version. The full client 

includes all of the required encryption libraries to enable online file submission, whereas the lite 

client does not include the encryption libraries and submissions must be made via CD. Note that 

only the full client is available for download from this page. To download the lite client, users 

must visit https://cdx.epa.gov/ssl/cdx/eTSCA-DownloadLiteClient.asp. 

Figure 2-2 eTSCA/e-PMN software download page

2.6 Navigation 

Navigating the eTSCA/e-PMN software is simple and intuitive. Most users will move through 

the forms in the navigation pane simply by using a mouse. Clicking on a section will highlight 

the title and open the corresponding form in the form editor window. 

Figure 2-18 Navigation Pane 

The left-right arrows on the upper-right corner of the toolbar [Figure 2-19] can be used as well. 

Figure 2-19 Navigation arrows 

2.6.1 Navigating using only the keyboard 

For users who prefer to work without a mouse, there are a number of keyboard shortcuts to 

navigate the eTSCA/e-PMN software. When the application focus is on the navigator window, 

the Up Arrow and Down Arrow will move forward and backward respectively through the 

forms in the navigation pane. Pressing Ctrl+F will manually give focus to the form editor 

window. With the application focus on this window, the Ctrl + Right Arrow and Ctrl + Left 

Arrow combinations will work to traverse the forms. Pressing the Tab button will toggle 

between fields within a form. If a table is encountered, tabbing will only move the focus amongst 

fields within that table. To exit the table and move the focus to the field following the table, press

Ctrl+Tab.

3 Using the eTSCA/e-PMN Reporting Software 

3.1 Saving a project 

Projects can be saved in an incomplete state to be finished later. Note that incomplete forms 

cannot be submitted to EPA. When Save or Save As is selected from the toolbar or the file 

menu, eTSCA/e-PMN automatically runs a validation check on the currently open form. If there 

are validation errors (due to invalid data or incomplete fields), the error message seen in Figure 

3-1 will appear, stating that the file was saved with validation errors. A validation window will 

appear at the bottom of the screen detailing the errors. 

Figure 3-1 File saved with validation errors

Double-clicking one of the listed items in the validation window will allow users to jump to the 

page of the error for easy correction. 

Saving a file without any validation errors produces the following dialog box, seen in Figure 3-2.

3.2 Closing a project 

Projects can be closed by selecting the Close command from the File menu. Selecting the Exit

command from the File menu will close the application completely. 

Figure 3-3 Closing a project 

3.3 Opening an existing project 

Opening an existing project is similar to creating a new one. Simply select the Open an Existing 

Form button ( ) or choose Open an Existing Form from the File menu to pop up the dialog 

box. Selecting a file type will filter the files that will appear on the following screen for file 

selection. 

Figure 3-4 Opening an existing project 
eTSCA CDX Registration Guide Using the eTSCA/e-PMN Reporting Software 

December 28, 2009 20

3.5 Confidential Business Information (CBI) 

Fields marked as CBI are highlighted in red for easier identification. These fields will be stripped 

out when a sanitized version is created. (See section 5.4.1 for details on sanitation). Some fields 

allow for curvy brackets (e.g., {CBI name}) to designate CBI. Any data between the curvy 

brackets in these large text fields will be replaced with XXX in the sanitized version. 

Figure 3-11 Confidential Business Information 

3.6 Contact Profiles 

Profiles make form completion more efficient by allowing users to pre-establish and save static 

information. With the simple click of a button, users can fill in contact information fields such as 

name, address, phone number, etc. or site information fields such as address and site name. 

Profiles are not Notice-specific. Once a profile is established for a current Notice, that profile is 

stored on the user’s local machine (as profiles.xml) and can be utilized later for any other 

eTSCA/e-PMN project. eTSCA/e-PMN has the ability to store multiple profiles. 

A profile can be added/modified by choosing Create/Edit Profile from the Tools menu or by 

clicking on the Profile button ( ) in the toolbar. The following window will appear. 

Figure 3-12 Profiles List Window 

The box displays a list of profiles currently stored on the machine. Clicking Edit or New will 

bring up the Create/Edit Profile dialog box, as seen in Figure 3-13 below. To edit an existing 

profile, highlight the profile name and click the Edit button. 
eTSCA CDX Registration Guide Using the eTSCA/e-PMN Reporting Software 

December 28, 2009 24 

Figure 3-13 Create/Edit Profile Window 

Existing profiles will display all fields currently populated, as well as any blank fields. New 

profiles will display all blank fields. The Profile ID field is used to identify the profile in the 

Profiles List dialog box—this field is required. All other fields are optional. To save the profile 

information, click the OK button. 

Note: If creating a profile for a user registered with the Central Data Exchange (CDX), it is 

imperative that the First Name, Last Name, and Company fields remain consistent with the 

information entered at the point of CDX registration. This information will be used for 

authentication. Incorrectly entered information will not pass validation upon submission via 

CDX. 

To use a profile within a form or dialog box, look for the “Copy from Profile” or “Profile” link 

wherever a contact or site information section is located on a form or dialog box. 

Figure 3-14 below exemplifies a section where a profile may be used.

3.7 Validation 

eTSCA/e-PMN provides data and business validations on both a field level and an application 

level. 

3.7.1 Field-level Validation 

Some fields contain special business rules that require inline validation. In the example seen 

below, the “TS Code” field requires a six-character alphanumeric string value. eTSCA/e-PMN 

handles these special validation cases by throwing an error at the point of field exit, preventing 

an invalid value to be entered. The error will specify the type of input expected for the given 

field. 

Figure 3-17 Field-level validation 

3.7.2 Application-level Validation 

eTSCA/e-PMN also performs application-level validation for the entire form. Validation can be 

activated manually at any time by choosing Validate from the Tools menu or clicking the 

validate icon ( ) from the toolbar. This action will start the validation checker, which opens the 

Validation window at the bottom of the screen and displays any validation errors and warnings. 
eTSCA CDX Registration Guide Using the eTSCA/e-PMN Reporting Software 

December 28, 2009 27 

Figure 3-18 Toolbar Validation icon 

Figure 3-19 Application-level validation 

Validation errors are critical errors that prevent the form from being submitted. Validation 

warnings point to potential problems in the form, but are not required to be corrected. 

Double-clicking one of the listed items in the validation window will allow users to jump to the 

page of the error for easy correction. 

Validation is automatically performed upon saving an existing project or finalizing a project for 

EPA submission. 

3.8 Printing 

Forms are easily printed with eTSCA/e-PMN. The software will create printer-friendly versions 

of forms in PDF format to facilitate this process. A PDF reader tool, such as Adobe Reader, will 

be needed to open the PDF files. 

A PDF copy can be generated by clicking on the Print command from the File menu [Figure 

3-20] or from the toolbar [Figure 3-21].

5 Pre-Manufacture Notice Form 

5.1 Usage 

Any organization planning to manufacture or import a new chemical substance for a non-exempt 

commercial purpose is required by Section 5 of TSCA to provide the Environmental Protection 

Agency with notice before initiating the activity. This Pre-manufacture notice, or PMN, must be 

submitted at least 90 days prior to the manufacture or import of the chemical. For more 

information on the New Chemicals Program, please visit: 

http://www.epa.gov/oppt/newchems/index.htm. 

The PMN form should be used to submit PMNs, SNUNs, LVEs and LoRex Exemptions and 

Modifications, TMEA exemptions, and Mock PMNs. 

5.2 PMN Navigation 

The toggle button seen in Figure 5-1 below will switch the view of the navigator window 

between displaying forms by name and by page number. 

Figure 5-1 Navigator Windows with titled by page name and page number 

 

5.3 Consolidated Submissions 

Up to six cases may be included in one submission. Any submission containing more than one 

case is considered a consolidated submission. 

Consolidated submissions require preapproval from the EPA. Contact EPA to receive a PreNotice Communication (PNC) number before attempting to submit a consolidated submission. 
eTSCA CDX Registration Guide Pre-Manufacture Notice Form 

December 28, 2009 37

Consolidated submissions do not need to be specified on the PMN page 1 in advance of adding 

extra chemicals. See the Adding, Deleting, or Cloning Chemical Data section for information on 

how to dynamically add or delete a chemical group. 

5.4 PMN-specific actions 

5.4.1 Sanitization 

Sanitization removes CBI data from the form so that the data can be shared with the general 

public. 

5.4.1.1 Creating a sanitized version of the PMN form 

Submitters should create a sanitized PDF to confirm that all CBI has been properly denoted and 

removed. A PDF file of a sanitized PMN form can be created by selecting Print Sanitized PMN

from the File menu or by selecting the Sanitize button ( ) from the toolbar. 
eTSCA CDX Registration Guide Pre-Manufacture Notice Form

Figure 5-4 Sanitizing a PMN 

5.4.1.2 Sanitizing attachment files 

File attachments marked as CBI require a sanitized version. The sanitized version must be 

created by the submitter and attached before submission. The validation checker prevents 

finalization of the submission until all CBI attachments have corresponding sanitized files 

attached as well. 

Figure 5-5 Sanitized file required 

5.4.1.3 Submitting a sanitized version of the PMN form 

When a PMN project is finalized for submission, a sanitized copy of the data is automatically 

generated within the finalized file. A separate submission is not required. 

5.4.1.4 Adding, Deleting or Cloning Chemical Data 

Users can add, delete, or create an exact copy (clone) of a chemical group (PMN Pages 4-6) by 

clicking on the respective menu items from the Edit menu or using the toolbar icons.

6 Notice of Commencement Form 

6.1 Usage 

A new chemical is eligible for addition to TSCA Inventory after the PMN review period has 

expired and the PMN submitter has commenced non-exempt commercial manufacture or import. 

The submitter of a PMN must provide a Notice of Commencement of Manufacture or Import 

(EPA Form 7710-56) to EPA within 30 days of the date the substance is first manufactured or 

imported for nonexempt commercial purposes. It will then be listed on the TSCA Inventory. 

Once a substance is listed on the TSCA (Toxic Substances Control Act) Inventory, it is 

considered an "existing" chemical. 

For more information on filing a Notice of Commencement, please visit 

http://www.epa.gov/oppt/newchems/pubs/filenoc.htm. 

6.2 Notice of Commencement tab 

The main form tab contains all the fields needed to complete a Notice of Commencement form.

7 Biotechnology Form (MCAN, TERA, TIER I & TIER 2) 

7.1 Regulation 

Under a 1986 intergovernmental policy statement and TSCA Section 5, intergeneric 

microorganisms (microorganisms created to contain genetic material from organisms in more 

than one taxonomic genera) are considered new chemicals. The Biotechnology rule sets forth the 

manner in which the Agency will review and regulate the use of intergeneric microorganisms in 

commerce, or commercial research. For more information, please visit: 

http://www.epa.gov/oppt/biotech/pubs/biorule.htm. 

These regulations create a reporting vehicle specifically designed for microorganisms, the 

Microbial Commercial Activity Notice (MCAN). Persons intending to use intergeneric 

microorganisms for commercial purposes in the United States would submit an MCAN to EPA 

at least 90 days before such use. EPA has 90 days to review the submission in order to determine 

whether the intergeneric microorganism may present an unreasonable risk to human health or the 

environment. 

The rules also address intergeneric microorganisms used in R&D for commercial purposes and 

create a vehicle for reporting on testing of new microorganisms in the environment, a TSCA 

Experimental Release Application (TERA). A TERA would be submitted to EPA at least 60 

days prior to initiating such field trials. The TERA is designed, in recognition of the needs of 

researchers, to provide a high measure of flexibility and a shorter review period of 60 days. 

Research & Development for commercial purposes are those activities which are funded directly, 

in whole or in part, by a commercial entity, regardless of who is actually conducting the 

research; or which will obtain for the researcher an immediate or eventual commercial 

advantage. For more information on Microbial Products of Biotechnology, please visit:

9 Submission Process 

9.1 Finalize Command 

Projects must be finalized before submission. The finalization process insures that the submitted 

data is valid and that all preliminary steps have been completed. 

Select Finalize from the Tools menu, or click the Finalize icon ( ) on the toolbar to begin the 

finalization process. The validation checker will then run. If a project fails validation, the user 

will not be able to continue until the necessary fixes are made. 

Figure 9-1 Cannot finalize due to validation errors

If no critical errors are found, the software will alert the user that a new report number has been 

generated for the current submission [Figure 9-2], and the Finalize Submission dialog box will 

appear [Figure 9-3]. 

Figure 9-2 New report number generated 
eTSCA CDX Registration Guide Submission Process 

December 28, 2009 53 

The user will be prompted to select a method of submission to the EPA. Three options will be 

displayed: 

• “I will submit my data electronically via CDX” 

• “I will submit my data via delivery service on a CD” 

• “I will submit my data on paper” 

Figure 9-3 Finalize Submission Dialog Box 

9.2 Paper Submission 

If the paper submission option is chosen, eTSCA/e-PMN will create a PDF file in your current 

working directory called “<Project Name>_finalized.pdf” and, if necessary, a suitable for 

submission sanitized PDF file called “<Project Name>_sanitized_finalized.pdf.” For example, 

a PMN project called “proj1.pmn_tsca” will produce a “proj1_finalized.pdf” submission file. 

 PDF files will contain a barcode on the top-left corner of each page. This is used by EPA for 

scanning purposes. 

If the form contains attachments, the finalized PDF will have a header page for each attachment. 

Attachments should be printed out (if not already a hardcopy) and placed behind each attachment 

header page. 

9.3 CD Submission 

If the CD submission option is chosen, eTSCA/e-PMN will create a “finalized” project file 

called “<Project Name>_finalized.<project_type_extension>” in the current working 

directory. For example, a PMN project called “proj1.pmn_tsca” will produce a 

“proj1_finalized.pmn_tsca” read-only file. The finalized file will contain the sanitized data. 
eTSCA CDX Registration Guide Submission Process 

December 28, 2009 54 

eTSCA/e-PMN will also create a certification PDF print out containing the MD5 checksum 

value of the file. This checksum number uniquely identifies the content of the finalized file. If 

the finalized file is changed in any way, the checksum will not be reproducible. In other words, 

the checksum guarantees that data has not been tampered with after it leaves the user’s hands. 

This file will use the naming convention “<Project Name>_cert.<project_type_extension>” 

(e.g., “proj1.pmn_tsca” will produce a “proj1_cert.pdf” file). 

The certification file will also contain the cover letter, the certification/signature page (PMN 

page 2) and the contact information page (PMN page 3). Please certify and sign when 

appropriate and submit the original with the CD to the EPA by courier. 

The finalized file must be burned to a CD and submitted along with a copy of the PDF printout 

containing the checksum. PMN and NOC form printouts must also be signed and dated. 

9.4 Online CDX Submission 

Only CDX registered users will be able to use the CDX submission option. Please see the CDX 

Registration Guide for more information on how to register with CDX 

((https://cdx.epa.gov/TSCA/ eTSCA-CDX_Registration_Guide.pdf). Users submitting on behalf 

of another organization must have registered the names of those companies and be authorized to 

submit for those organizations. 

After selecting the Finalize button and after choosing to submit via CDX, eTSCA/e-PMN creates 

a “finalized” project file called “<Project Name>_finalized.<project_type_extension>” in a 

directory of your choosing. For example, a PMN project called “proj1.pmn_tsca” will produce a 

“proj1_finalized.pmn_tsca” read-only file. 

Users will be prompted to enter a username and password in order to login before submission 

[Figure 9-4]. 
eTSCA CDX Registration Guide Submission Process 

December 28, 2009 55 

Figure 9-4 Login to CDX from eTSCA/e-PMN software 

eTSCA/e-PMN software will verify the submission information with CDX registration. If the 

data agrees, eTSCA/e-PMN will display a message informing the user that a finalized version of 

the file is being created.

Figure 9-7 Node Client 

Click the “Submit File to CDX” button to continue the submission process. 

9.4.1 User Certificate and Key Pair Generation 

A user certificate and Private/Public Key pair is used to digitally sign and encrypt the submitted 

documents, providing security protection for eTSCA/e-PMN submissions. The certificate and 

key pair will be automatically obtained by the Node Client after the first login. 

The Node Client stores the following data into a keystore under the user home directory: 

• user ID 

• user private key 

• user certificate 

• creation time 

The following file will be created: \<userHome>\ .<userId>-cromerr-keystore.jks where 

<userHome> is a local user home directory (C:\Documents and Settings\myuser) and <userId> is 

an eTSCA/e-PMN user ID registered with CDX Web. Since this file is stored on the user’s local 

drive, the user will only be able to access the submitted documents from this specific machine 

unless the key file is copied into the same location of another machine. In any case, the user can 

copy this file to another safe location for backup, if desired. 
eTSCA CDX Registration Guide Submission Process 

December 28, 2009 58 

Upon clicking the “Submit File to CDX” button, the user will need to complete the electronic 

signature agreement and verify his or her identify. The following screens will be displayed.
