Annual Report templates are here!

There are two versions of the Annual Report template: one for existing 2004 MS4 permittees and another for new 2017 MS4 permittees. They are nearly identical – the biggest difference is that the due dates for many BMPs are later for new permittees. DEEP  strongly encourages using these templates but they’ll accept other formats that include all permit reporting requirements.

The templates can be found under the Implementation section > Annual Reports and they’re saved as Microsoft Word documents to allow for easy editing.  If you have any trouble working with the document – feel free to reach out to me (Amanda) I might be able to help!

Timeline for completing the report: Notify the public about the pending availability of the Annual Report and Stormwater Management Plan by January 31st. The deadline to actually post the report and plan to your website is February 15th. Then the final report should be submitted to DEEP by April 1st.




Green infrastructure demonstration sites at East Lyme beach parking lot

After 7 years of diligent stormwater infiltration, it seems like a lot of people know about the green stormwater infrastructure (GSI) practices at the Hole-in-the-Wall beach parking lot in East Lyme – in no small part due to the stormwater classroom held here every year.

Permeable paver demonstration

Each May, town staff with help from many partners including CT DEEP, Southern Connecticut Regional Resources Recovery Authority, Ledge Light Health District, and teachers and students from East Lyme’s Middle and High schools host a stormwater classroom at the beach for all third grade students (and this year students from Salem participated too). This event has become a time-honored East Lyme tradition and a key part of their MS4 public outreach and education program.

It’s worth visiting anytime if you’re interested in seeing many different types of pervious surfaces and how they’ve fared after many years with minimal maintenance.  Bill Scheer (bscheer@eltownhall.com) Deputy public works director or Victor Benni (vbenni@eltownhall.com) Town engineer, would be happy to share their insights and favorite treatments from the perspective of people responsible for their original installation and ongoing maintenance.

In addition to ten different types of pervious surfaces, you can see an above ground hydrodynamic separator (very rare opportunity!), a tree box filter, a rain garden, and a series of detention/infiltration basins which are the last line of defense before stormwater and all it carries with it from a 23-acre watershed empties into Long Island Sound.

Take a look at this PowerPoint for pictures of all the green stormwater infrastructure practices at Hole-in-the-Wall Beach.


MS4 Management Software Demos

Several folks have been asking if there is a software program available to help manage MS4 activities and reporting under the new permit. We have found a couple of options: PermitTrack and MS4Front.

To help you compare the two and evaluate whether they would be of use to you, we held webinar demos for each on Feb. 15. See recordings of the webinars below.

Webinar – Getting Started with Your SWM Plan

NEMO is holding a webinar on Tuesday February 7 at 2pm focused on the first step in your journey through the new MS4 General Permit requirements – registration and your Stormwater Management (SWM) Plan.

For the 121 communities (plus institutions) covered under CT DEEP’s newly revised “MS4” stormwater regulations, the first requirements are to develop (or revise) a Stormwater Management Plan (SWMP) and register as an MS4. Draft SWMPs are to be posted for public comment and submitted to CT DEEP by April 1, 2017. That’s 2 months away. Yikes!

Fear not, this presentation will cover what’s required to be in the plan, share a template for a SWM Plan that you can adapt and use, and introduce you to NEMO’s new MS4 Online Guide (the website you are on now) – a repository for tools, maps and information related to the permit.

The webinar will be presented by our new MS4 Circuit Rider, Amanda Ryan, and Dave Dickson.

The webinar recording can be found on our Webinars Page (in the Tools section).
