Certification for Nonroad (NR) Spark-Ignition (SI) Engines
Follow these steps for certification.
STEP 1: Confirm that you have access to EV-CIS.
STEP 2: Update manufacturer information in EV-CIS.
To update information, users must have the "Maintain Manufacturer Information" role in EV-CIS. Otherwise, users will only be able to view the information.
- Industry sector(s);
- Addresses;
- Contacts and Industry/Compliance Programs;
- Test labs; and
- Notification email addresses (used for EV-CIS' broadcast notifications).
STEP 3: Review all applicable regulations.
Regulations provide requirements for certification and compliance.
- 40 CFR Part 1045
Control of emissions from new, gasoline boats and personal watercraft. - 40 CFR Part 1048
Control of emissions from new large spark-ignition engines. - 40 CFR Part 1054
Control of emissions from new, small nonroad spark-ignition engines and equipment. - 40 CFR Part 1060
Control of evaporative emissions from new and in-use nonroad and stationary equipment. - 40 CFR Part 1065

STEP 4: Pay appropriate certification fees, as applicable.
A fee payment may be required for each certificate issued by EPA.
For more details, go to: Fees Information
STEP 5: Prepare certification application materials.
For each model year for a family, you must provide the applicable certification dataset and supporting materials.

STEP 6: Submit the completed certification application materials in EV-CIS.
Login to EV-CIS through the CDX portal: Central Data Exchange (CDX)
Click the applicable industry role on the MyCDX homepage.
Submit the completed certification dataset and upload any required supporting materials.
STEP 7: Confirm that your submission(s) from Step 6 were accepted by EV-CIS.
Within a few minutes of all submissions, the submitter will receive a notification in their CDX inbox indicating whether the submission was accepted or rejected.
To access your CDX inbox, click the "Inbox" link on the left navigation bar of the MyCDX homepage.
STEP 8: Submit a request for certificate (RFC).
A CROMERR signer must submit an RFC for each Engine Family.
To do so, click the "CROMERR Signer" role on your MyCDX homepage.
- For more about submitting an RFC, see: Webinar and Demonstration about RFC
STEP 9: Receive Certificate of Conformity.
The CROMERR signer will receive the certificate in his or her CDX inbox.
