BRF Ranking Document: CLICK HERE

As required by legislation, the Department must rank all Best Available Technology systems for removing nitrogen for onsite sewage dispersal systems. Rankings are to be provided for the following factors:

Total Nitrogen reduction for the technologies
Total Cost of the technology to include operation/maintenance and electrical consumption
Cost per pound for nitrogen reduction.

The Department is to provide to the public this ranking of BAT systems. This ranking is largely based on information provided by the vendors. The Department strongly advises the applicant to contact each vendor directly for more information.

The BAT Technical Review Committee is accepting applications for determining systems for consideration as BAT and eligibility for Bay Restoration Fund grants.
