Important! MASTEP status rating numbers do not equate directly to BMP performance. They rate the availability of credible performance data for a technology. A #1 rating does not necessarily mean a BMP performs better than one rated #2 or #3; it means you can have more confidence in performance evaluation studies of that product. Please read the data review explanation before making any decisions based on the information provided in this database. |
