Each MS4 must submit an Annual Report indicating progress on implementing their stormwater management plan. CT DEEP strongly recommends using these templates but alternate formats will be accepted as long as all the required information is provided.
There are two different Annual Report templates: one for existing 2004 MS4 permittees and one for new 2017 MS4 permittees (8 new towns and all institutions).
We developed a short video to provide an overview on completing the Annual Report and explain the submission process:
- Notify the public when the Annual Report and stormwater management plan will be made available for review and describe the process and the point of contact for providing comments no later than January 31st (see page 21 of the general MS4 permit for all the details). Providing earlier notice is encouraged.
- Post the Annual Report and current stormwater management plan to the town or institution website by February 15th (see page 16 of permit for details). Also have hardcopies of the report and plan available at town hall or a public library.
- Submit the Annual Report to DEEP by Monday, April 2nd, the first business day after April 1st (see page 45 of permit for details). Mail the review fee which is $375 for institutions and $187.5 for municipalities and the Annual Report transmittal form (download here) to CT DEEP Central Permit Processing Unit and email an electronic copy of the Annual Report to DEEP.Stormwaterstaff@ct.gov.
In the past, MS4 communities were able to use a software called Assist to manage compliance with the MS4 permit and produce annual reports. That program is unfortunately no longer supported by the company. However, there are other companies that offer similar programs. NEMO is reviewing those options and will post more information here when it is available.
Some of the programs we are currently reviewing include:
