[owtsinfo at listserve.ri.gov]

N-removal systems approved under Rule 37.4.2(B)(i) are subject to
monitoring of 10 systems (7 year round and 3 seasonal).   A maximum of
50 of each of these systems will be approved until sufficient data are
received through the RIDEM monitoring protocol indicating treatment
objectives are being achieved.

As of March 23, 2015 the number of approvals, for sites requiring
nitrogen reduction, for each of these technologies are listed below:

*         Norweco, Inc. Singulair TNT: 50* systems approved 

*Absolutely NO additional permits proposing the Singulair TNT will be
accepted for sites requiring nitrogen reduction until sufficient
sampling, testing & reporting have been completed.

*         Orenco Systems Incorporated AdvanTex AX-RT: 33 systems
approved 

*         Norweco, Inc. Hydro-Kinetic: 3** system approved 

** No additional Hydro-Kinetic systems will be accepted for a review
until the proposed Vendor training is completed.

Designers considering specifying any of these technologies in a design
plan for submission to the DEM OWTS Program, are advised to contact the
Permitting Program before initiating the design, for an update on the
number of these systems that have been approved.
