Chemical Technology Assessment Protocol - Ecology (CTAPE)

Ecology's CTAPE program establishes the testing protocol and process for evaluating and reporting on the performance and appropriate uses of emerging temporary stormwater chemical treatment technologies. Generally, these temporary chemical treatment technologies are utilized at active construction sites.

Technologies that have been approved by the CTAPE program can be found on Ecology's website, under the Construction Treatment category.

The CTAPE Guidance Manual can be found here.
