Requirements for Verification of Clean Diesel Technology
Before applying for verification of your Clean Diesel Technology, consider the following:
- Regulatory requirements
- Documentation requirements
- Requirements for the applicant
- Requirements for availability of technology
- Requirements for health effects and safety of technology
- Requirements for intended market for technology and documentation from in-use experience
Some technologies may not qualify for verification as the product may have regulatory requirements that supersede verification. For example, manufacturers that convert diesel engines to operate on alternative fuels (CNG or LNG) must follow the regulatory requirements for certification and consequently these engine conversions could not use the verification process.
Additionally, some technologies may have regulatory requirements that must be addressed prior to applying for verification. For example, there may be regulatory requirements for safety or health effects that need to be addressed.
- For more information, go to: Register a fuel or fuel additive
- How the technology works
- Basis for emission reduction claims
- Intended market application and engine groups
- Potential unique testing needs
- Operating criteria, including any operating constraints (e.g., ambient air temperature or conditions, backpressures, etc.)
- Potential concerns for health or safety
- How and where the technology is installed on the vehicle
- Experience with in-use operation of the specific technology and similar designs
- Previous testing
The person applying for verification must be an official manufacturer representative with detailed knowledge of the technology, its manufacture, in-use operation, performance, durability and prior testing.
- All information submitted for application is correct;
- The technology will be manufactured and installed as described;
- The technology will perform as described.
The retrofit technology submitted for verification must be commercially available for installation. No products still in the research and development stage will be verified.
Concerns with health effects or safety may need to be addressed prior to EPA review of a technology for verification.
Manufacturers should identify specific engine and vehicle types for the intended market segment, and provide documentation from in-use experience. EPA has grouped together engine families with similar emissions performance characteristics for verification purposes. The retrofit manufacturer may provide test data showing that a product tested on one engine family may be applied to other similar engine families.
