We've made some changes to EPA.gov. If the information you are looking for is not here, you may be able to find it on the EPA Web Archive or the January 19, 2017 Web Snapshot.

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 required 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. Petitions for imports of used ODS (for both destruction and reuse) must also be submitted through CDX.

EPA hosts training webinars to provide additional information on these recent changes. Listen to a recent webinar.

Petitions

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.

The petition must be submitted electronically through CDX, on an as needed basis, and 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?
  7. If it is used halon, was it from a halon bank?

Imports for Destruction

Requirements and procedures for the Agency’s import of both used and virgin Class I and II ODS for destruction are available in 40 CFR 82.13(g)(5) – (10) and 40 CFR 84.24(c)(6) – (11). A Certification of Intent to Import ODS for Destruction must be received by EPA 30 working days before the shipment is to leave the foreign port of export.

The Certification of Intent to Import for ODS Destruction must be submitted electronically through CDX and must include this information:

  1. How much is being imported for destruction?
  2. Who is the importer and who are the intermediaries assisting in aggregating the ODS for destruction?
  3. Which U.S. Port of entry and when is the exempted date of arrival?
  4. Which country is it being export from?
  5. Who is destroying the ODS and where is the facility located?

Recent Updates to ODS Reporting

All reporting forms are available in a Microsoft Excel format for electronic submission.

What are the improvements?

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

• Smarter: Strong protections for confidential business information (CBI)

• 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 e-reporting forms contain data validation capabilities that prevent incorrect entries. These validations reduce error and inefficiencies associated with manual submittal.

• Smarter: 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.

• Streamlined: ODS reporting requirements are now the same for both class I and II substances including the timing and frequency of submissions and the requirements for attachments.

What remains 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.
