Expired Stormwater Manufactured Treatment Devices

NOTICE (Originally issued September 1, 2011)

The manufactured treatment devices (MTDs) on this page are only approved as off-line water quality devices unless certification specifically states otherwise or unless the Department has issued a letter to indicate that it can be used as an on-line water quality device. An on-line water quality device allows the passing of storms greater than the NJDEP water quality design storm through the device. Projects that have been deemed administratively complete by the Division of Land Use Regulation for a permit requirement stormwater review as of September 1, 2011 may continue to utilize the design as specified in the prior certification letters. If no permit is required from the Division of Land Use Regulation, projects that have been deemed administratively complete by the municipality as of September 1, 2011 may continue to utilize the design as specified in the prior certification letters.

NOTICE (Originally issued January 25, 2013)

MTDs that are set to expire on September 1, 2013 have been issued a new expiration date of January 25, 2015.

The certifications listed on this page are for site design projects that received preliminary or final site plan approval prior to January 25, 2015 or additional grandfathering listed at N.J.A.C. 7:8-1.6.
