Changes

Existing ‘General Use Level Designation’ certification of Filtration MTDs through the Washington TAPE process may satisfy ETV testing requirements in Canada provided that the design of the tested unit has not changed, TAPE requirements were followed, and hydraulic laboratory testing is used only to augment, rather than replace field testing requirements.  In some cases, additional testing and data analysis may be required to support the ISO 14034 verification.

A list of TAPE approved Filtration MTDs with General Use Designation can be found on the Washington TAPE website, along with technical reports for each device. You can find the list of over 106+ approved devices here [https://ecology.wa.gov/Regulations-Permits/Guidance-technical-assistance/Stormwater-permittee-guidance-resources/Emerging-stormwater-treatment-technologies#tape Emerging stormwater treatment technologies (TAPE)]. The following table on the TAPE website lists the devices that have received a use designation through the TAPE process. These use designations can be divided into three separate Use Level Designation (ULD) categories:

A list of TAPE approved Filtration MTDs with General Use Designation can be found on the Washington TAPE website, along with technical reports for each device. You can find several Filtration MTDs on the TAPE approved list of stormwater technologies here: [https://ecology.wa.gov/Regulations-Permits/Guidance-technical-assistance/Stormwater-permittee-guidance-resources/Emerging-stormwater-treatment-technologies#tape Emerging stormwater treatment technologies (TAPE)]. The following table on the TAPE website lists the devices that have received a use designation through the TAPE process. These use designations can be divided into three separate Use Level Designation (ULD) categories:

# '''General Use Level Designation (GULD'''): Known technologies whose given evaluation report showcases that they can confidently achieve Washington state Technology Assessment Protocol - Ecology's required performance goals.

# '''General Use Level Designation (GULD'''): Known technologies whose given evaluation report showcases that they can confidently achieve Washington state Technology Assessment Protocol - Ecology's required performance goals.

# '''Conditional Use Level Designation (CULD)''': These are technologies that should most likely and feasibly be able to meet stated performance goals, but the developer most conduct additional verification field testing (within a given time period) to achieve General Use Level designation.
