EPA Updates eNOA Template in CDX System

Richard E. Engler, Ph.D.

The U.S. Environmental Protection Agency (EPA) has updated its eNOA upload template that was initially released in 2017 to assist filers with the Central Data Exchange (CDX) system.  The eNOA, or electronic Notice of Activity (NOA) Form, is used for retrospective reporting under the amended Toxic Substances Control Act’s (TSCA) Inventory notification requirements.  The eNOA template, available for download from within the eNOA system on CDX, assists users to upload many substance identities in a batch.  The template file is a comma separated value (CSV) file, CSV-NAA.csv, that is readable by most spreadsheet and database programs.  The change means that if submitters attempt to use the old template, the CSV file will not upload properly and will generate errors in CDX. 

The template was updated by adding a new field name.  The new field name that will be added to the CSV file is “Isjoint,” and the field explanation is “NOA is joint with another submitter;” which permits filers to upload and start multiple joint submissions in a batch.  The field names required, along with their field explanations, are: 

  • Isjoint: NOA is joint with another submitter.
  • CASRN:  CASRN with our without dashes; after upload, dashes will be present.  Must be “TRUE” or “FALSE”;
  • Accession Number:  Accession number for substances listed on the confidential portion of the Inventory;      
  • Chemical Cbi:  Submitter seeking to maintain CBI claim for substance identity.  Must be “TRUE” or “FALSE”;
  • Submitter Cbi: Submitter claiming CBI for submitter identity.  Must be “TRUE” or “FALSE”;
  • Company Details Cbi: Submitter claiming CBI for submitting company details.  Must be “TRUE” or “FALSE”;
  • Technical [Contact] Cbi:  Submitter claiming CBI for technical contact identity.  NB: “Contanct” is misspelled in the template.  Must be “TRUE” or “FALSE”;
  • Substantiation CBI:  Submitter claiming CBI for substantiation statement(s).  Must be “TRUE” or “FALSE”; and
  • ShowCbiQuestions:  Set to TRUE to substantiate CBI claims.  This is required for submitter, company, and technical contact claims.  Must be “TRUE” or “FALSE.”
