Ozone-Depleting Substances (ODS) Recordkeeping and Reporting

EPA has issued a series of regulations to phase out the production and import of Class I and Class II ozone-depleting substances (ODS). The regulations include reporting and recordkeeping requirements for producers, importers, and exporters of Class I and Class II ODS. EPA provides reporting forms and instructions to assist entities in fulfilling these requirements. These Microsoft Excel-based reporting forms are designed to be submitted to EPA through the Central Data Exchange (CDX). To submit a report through CDX, you will first need to register with CDX and sign an electronic signature agreement.

On July 1, 2018 EPA updated the ODS data submission process. ODS reporting forms are now available in a Microsoft Excel format for electronic submission. 

EPA hosted training webinars to provide additional information on these recent changes. Listen to a recent webinar. The following links exit the site Exit

Class I and methyl bromide reporting forms are due 45 days after the end of the reporting period. Class II reporting forms are due 30 days after the end of the reporting period. A detailed control period calendar identifying when specific reports are due is also available.

EPA allows the import of used ODS to ease the transition to ODS alternatives. EPA has a petition process to verify that the ODS were actually used. Petition requirements are available in 40 CFR 82.13(g)(2) and 40 CFR 82.24(c)(2), (3), and (4). EPA must receive the petition 40 working days before the shipment is to leave the foreign port of export.

There is no EPA petition form. The petition may be in any format, on an as needed basis, but must include the following information about the used ODS:

  1. From what type of equipment was it removed?
  2. Who removed it?
  3. When was it removed?
  4. How much was removed?
  5. What chemical was used to replace the ODS, or was new equipment installed, or was the equipment no longer needed?
  6. If new equipment was installed, what type of equipment is it?

Submit your petition information through so EPA can track your submittal and respond in a timely manner.

Recent Updates to ODS Reporting

EPA updated the ODS data submission process. As part of this update, all reporting forms are available in a Microsoft Excel format for electronic submission. These changes went into effect on July 1, 2018. 

Why has the process changed?

• To streamline and improve the ODS reporting forms and data submission process.

• To coincide with timing of the ODS Tracking System upgrade.

• To maintain strong protections for confidential business information (CBI)

What changed?

New and improved e-reporting capability for all reporting needs.

• Streamlined: EPA consolidated the 36 reporting forms (28 print-ready and eight electronic) into 16 electronic forms. Print-ready forms are no longer available.

• Smarter: The new e-reporting forms contain data validation capabilities that prevent incorrect entries. These validations are designed to reduce error and inefficiencies associated with manual submittal.

New features to the online submission.

• Streamlined: The new application includes a submission history table that is easily searchable and viewable by all users within the same organization.

• Smarter: The new application includes validations that help ensure accurate and complete report submission packages.

New method for receiving EPA communications.

• Streamlined and Smarter: Communications from EPA are now sent electronically through CDX.

What remained the same?

• Secure Method of Reporting: All CBI and security procedures for online reporting remain. EPA places a major emphasis on the security of reported data.

• Method of Reporting: Online reporting continues to rely on CDX.

• Electronic Reporting Format: The e-reporting forms remain in Microsoft Excel. The process of generating a csv file also remains a critical step in the process of reporting.

• Reporting Requirements: ODS reporting requirements remain the same including the timing and frequency of submissions and the requirements for attachments.
