Stormwater Manufactured Treatment Devices

An MTD is required to be NJCAT verified and NJDEP certified when the MTD is used to satisfy the requirements of the Stormwater Management rule (N.J.A.C. 7:8), as a result of triggering the requirements for major development.

For projects receiving New Jersey Environmental Infrastructure Financing Program (NJEIFP) funding, an MTD must be either: 1) NJCAT verified and NJDEP certified or 2) installed using the NJEIFP MTD Funding Policy.

An MTD which is not NJCAT verified or NJDEP certified may be used as long as the MTD is not intended to satisfy the requirements of the Stormwater Management rule and is not subject to NJEIFP MTD Funding Policy.

Please note that any MTD installed should be listed on the MS4 permittee’s inventory of stormwater management measures and must be properly maintained by the responsible party. Other state, federal and local requirements may apply.

NOTICE (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 (January 25, 2013)

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