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 (January 13, 2017)
NJDEP Field Test Certifications for MTDs expired December 1, 2016. As such, MTDs that held only the Field Test Certification can no longer be used in new installations to satisfy the requirements of the Stormwater Management rule. However, projects that have been deemed administratively complete by the Division of Land Use Regulation for a permit requirement stormwater review as of December 1, 2016 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 received preliminary or final site plan approval from the municipality as of December 1, 2016 may continue to utilize the design as specified in the prior certification letters.
For MTDs to be recognized in New Jersey for an approved TSS removal rate, the MTD must have NJCAT verification and NJDEP certification under the updated procedures and protocols dated January 25, 2013. Guidance for obtaining verification and certification can be found at the NJDEP website at http://www.njstormwater.org/mtd_guidance.htm.
The list of MTDs with expired Field Test Certifications can only be found at the Expired Stormwater MTDs page located at http://www.njstormwater.org/mtd_expired.htm.
The table below includes the listing of MTDs that are NJCAT verified and NJDEP certified under the updated procedures and protocols dated January 25, 2013.
