Ecology implemented a new water quality permit database system called PARIS on April 19, 2010. When reviewing data that was entered before and after that date, you may see differences. In addition, permits that were cancelled or terminated before that date may not be in PARIS. If you have questions, would like to report inconsistencies, or need data for permits not in PARIS, please contact the “Ecology Contact” found on the Facility Detail Page.
