Understanding the Canadian Environmental Technology Verification (ETV) Program for Stormwater Equipment Manufacturers Part 2

Verification for Stormwater Equipment Manufacturers

Oil grit separator (OGS) manufacturers can get their equipment verified in two different ways. One is, if they already have data that has been approved by another nationally recognized program such as the New Jersey Centre for Advancement of Technology (NJCAT), they can submit that data for verification immediately and additional testing is therefore not required.   Because NJCAT allows for testing to be done at the manufacturer’s site with an independent witness while ETV requires that testing be done at an independent lab, not all data accepted by NJCAT will be acceptable to ETV.

The other way is if an OGS manufacturer does not already have an acceptable dataset. In this route, data must be generated by following the ETV OGS protocol. Details of the protocol can be found at Running these tests will require the manufacturer to work with an independent testing lab.

For filter manufacturers, there are also two options for verification. The first is the same as for OGS manufacturers. If they have NJCAT data that was generated at an independent lab, they can submit it as is. If new testing is required, the procedure differs slightly because there is no filter protocol in place at the present time. In this case, it is necessary to develop a claim and a test plan in accordance with the General Verification Protocol (GVP).

The process outlined in the GVP calls for generating the required data and then contacting the CETV Program. In principle, this is reasonable if the manufacturer is very confident in their data. In practice, it is wise to contact CETV before doing testing. There are grey areas in the protocols regarding how to build a proper test plan so it is a good idea for both OGS and filter manufacturers to do their due diligence in making sure their proposed test plan is going to be acceptable to their verifying organization.

For manufacturers of other types of treatment technology that are significantly different from an OGS or a typical filter there is only one option for verification. Since there is no existing protocol to work with it is necessary to put together a technology specific test plan (TSTP) from scratch. It then gets approved by the Verifying Organization and proceeds from there. Pre-commercial technologies can follow this same path. This allows a new technology to gain recognition and demonstrate proof of principle, which then allows it to be fast tracked for verification once it’s commercialized.

Pre-commercial technologies are required to put together a project team consisting of:

  • The proponent
  • An expert independent test agent, who will be involved with the proof of principle test program (or a named laboratory, institution or test agency)
  • The Canadian ETV Program
  • The Verification Organization
  • A funding program in which the project is supported (optional)

This project team is also a good idea for commercialized products that are developing their own TSTP.

Good Harbour Labs has participated in developing test plans for OGSs, filters and pre-commercial technologies. We are able help manufacturers efficiently navigate the process. For more information contact
