(Introduce ourselves on next slide)

3. Interlocal Stormwater Working Group
CCSWCD facilitates the ISWG group
Brings together 14 communities in the Greater Portland and Saco areas to work together on stormwater issues

4. Clean Water Act
Regulated municipalities must have a permit to direct runoff to water bodies in their communities and requirements to minimize pollution must be met.
Federal Clean Water Act dictates that
Regulated municipalities must have a permit to direct runoff to water bodies in their communities and requirements to minimize pollution must be met.

5. Regulatory Background
City of Westbrook MS4 O&M Training
Regulatory Background
Federal Authority
National Pollutant Discharge Elimination System
(NPDES)
CLEAN WATER ACT > Authorizes Environmental Protection Agency > Authorizes Maine DEP
Maine program administered by DEP
40 stormwater permits issued under the program
30 municipalities, 10 “other” agencies (transportation agencies, public universities, prisons, military bases, and other state and federal facilities)
State Delegated Authority
Maine Pollutant Discharge and Elimination System
(MPDES)

6. Municipal Permit Municipal Separate Storm Sewer System (MS4)
5-year permit cycles, first permit issued in 2003
Additional regulations in each permit cycle
Next permit due in 2018
Municipal permit is known as the MS4 permit (Municipal Separate Storm Sewer System)
Program has been around for a while; first permits issued in 2003
Updated every 5 years
Each permit builds on the previous permit - new and increased requirements with each new permit
Next permit 2018

7. Municipal Permit Municipal Separate Storm Sewer System (MS4)
Public Education & Outreach
Public Involvement & Participation
Illicit Discharge Detection & Elimination
Construction Site Runoff Control
Post-Construction Stormwater Management
Pollution Prevention & Good Housekeeping
Municipal permit has extensive requirements within the categories listed above – also sometimes called Minimum Control Measures or MCMs
We’re focusing in on Illicit Discharge Detection & Elimination AND Construction Site Runoff Control
Define “illicit discharge”
Define “urbanized area”

8. Regulatory Background
MS4 requirements that effect CEOs
Adopt and enforce a non-stormwater discharge ordinance / detect and eliminate illicit discharges
Inspect to ensure compliance with MCGP & Ch. 500 requirements for construction sites 1 acre or greater
Any construction project within the urbanized area with 1 acre or more of disturbance, must meet the requirements of the MCGP
Construction projects under an acre may cause an illicit discharge to the stormwater system and therefore erosion & sedimentation control is critical on those projects as well

9. Non-Stormwater Discharge Ordinance
Sometimes referred to as the Illicit Discharge Ordinance
Forbids discharge of ANYTHING other than stormwater into the stormwater system
With a few exceptions - allowable non-stormwater discharges
Talk about uncontaminated groundwater from underdrains, foundation drains, etc.

10. Spill Response / Illicit Discharge
City of Westbrook MS4 O&M Training
Spill Response / Illicit Discharge
Proper response is NOT to sit down and drink the spilled material. (This is my sarcastic humor. It may come up again.)
March 24, 2016

11. Spill Response / Illicit Discharge
See it. Stop it. Say something.
Our new catch phrase for spill response. What do you think?

12. Spill Response / Illicit Discharge
(Ask them to respond!)
Oil – petroleum product
DEP must be notified of any oil spill (municipal policy might have threshold, Maine wants to know about ALL spills)
What do you see here?

13. Spill Response / Illicit Discharge
(Ask them to respond!)
Intentionally pouring material into storm drain
This never happens, right??!!?!
What do you see here?

14. Spill Response / Illicit Discharge
(Ask them to respond!)
Gray water discharge to ditch – might smell like detergent, might have bubbles
What do you see here?

15. Spill Response / Illicit Discharge
(Ask them to respond!)
Illicit discharge from tracking sediment from construction site
What do you see here?

16. Spill Response / Illicit Discharge
(Ask them to respond!)
Erosion into waterway – from construction? Agriculture?
What do you see here?

17. Spill Response / Illicit Discharge
See it.
Stop it.
Say something.
Remember – see it, stop it, say something. Well, we’ve seen things. Now what?

18. Stop it Exercise your authority – tell them to stop
If it’s a spill, can you use something to contain it?

19. Say something
Who in your municipality is responsible for tracking illicit discharges? Stormwater coordinator?
THE SPILL / DISCHARGE NEEDS TO BE RECORDED. And, they may want to check to see if it entered the stormwater system or if further response is needed.

21. Erosion vs. Sedimentation SPECIAL NOTE
City of Westbrook MS4 O&M Training
Erosion vs. Sedimentation SPECIAL NOTE
Special note . . .
Which one depicts erosion? Which depicts sedimentation?
Is it better to prevent erosion or control sedimentation?
Who has heard of “RUN – ON?”
March 24, 2016

22. Erosion Control Plan
Projects 1 acre or greater are required to have ESC plan on site. You can ask (and should ask) to see it.

23. Self-Inspection Records

24. City of Westbrook MS4 O&M Training
Materials Storage
Stockpiling issues.
What could be done here?
What BMPs would you recommend here?
March 24, 2016

25. City of Westbrook MS4 O&M Training
Materials Storage
Tarp it
Contain it
March 24, 2016

26. Tracking What BMPs would you recommend for tracking?
Tracking is a big problem. Cumulative effect is huge.
What BMPs would you recommend for tracking?

27. Tracking
Stabilized construction entrance, street sweeper for larger projects
Broom for small jobs

28. City of Westbrook MS4 O&M Training
Inlet Protection
How are these two pictures related?
What could be done to prevent this?
Don’t park over the drain
Use inlet protection
March 24, 2016

29. Inlet Protection Inlet protection must be maintained in good condition
Care must also be used when removing these
MORE THAN ONE PERSON is needed

30. City of Westbrook MS4 O&M Training
Erosion Controls
Someone didn’t know what they were doing here
How are these two pictures related?
March 24, 2016

31. City of Westbrook MS4 O&M Training
Erosion Controls
Jute netting
Check dams
Straw wattle – staked in, of sufficient height
March 24, 2016

32. Erosion Controls A big mess
Silt fence with vegetated buffer – not right at the edge of the disturbed ground

33. Site Stabilization Temporary stabilization – jute netting, hay mulch
Permanent stabilization – sod (instant), hydroseed (takes a while – should check during/after storms)
What else can be permanent stabilization that is NOT SHOWN - pavement, cement

34. Trash and Debris
No liquids, not overflowing, not rusted out and leaking, ideally covered

35. Dust Control
Sprayers – water NEVER OIL

36. Dewatering Dirt bags Settling basin Silt sock
They should have a PLAN – and they need to stick to the plan or get approval for something different

37. Enforcement Discussion
Non-stormwater discharge ordinance does not provide authority to municipalities to enforce against larger construction projects.
How can municipalities ensure compliance with MCGP and Ch. 500?
Authority through another ordinance or code?
Call DEP for enforcement?

38. Reporting and Recordkeeping
Comprehensive records documenting compliance with all permit requirements must be kept.
Without the record, it didn’t happen
Paper trail for all enforcement

39. Interdepartmental Coordination
Public Works Department
Planning & Code
Parks and Recreation
School Department
Public Safety
Wastewater Treatment
Essential to the success of your municipal stormwater program
NOT A ONE PERSON JOB – you are not alone!
Departments must work together to meet the permit requirements
Each department has responsibilities under the stormwater program
