Erosion and Sedimentation Control This is just to show you that you’re in the right place For Code Enforcement Officers Heather McNally, Technical Specialist Jodie Keene, Outreach Coordinator
Introductions Name Municipality Role/Title (Introduce ourselves on next slide)
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
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.
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) March 24, 2016
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
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”
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
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.
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
Spill Response / Illicit Discharge See it. Stop it. Say something. Our new catch phrase for spill response. What do you think?
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?
Spill Response / Illicit Discharge (Ask them to respond!) Intentionally pouring material into storm drain This never happens, right??!!?! What do you see here?
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?
Spill Response / Illicit Discharge (Ask them to respond!) Illicit discharge from tracking sediment from construction site What do you see here?
Spill Response / Illicit Discharge (Ask them to respond!) Erosion into waterway – from construction? Agriculture? What do you see here?
Spill Response / Illicit Discharge See it. Stop it. Say something. Remember – see it, stop it, say something. Well, we’ve seen things. Now what?
Stop it Exercise your authority – tell them to stop If it’s a spill, can you use something to contain it?
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.
Erosion & Sedimentation Control City of Westbrook MS4 O&M Training Erosion & Sedimentation Control March 24, 2016
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
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.
Self-Inspection Records
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
City of Westbrook MS4 O&M Training Materials Storage Tarp it Contain it March 24, 2016
Tracking What BMPs would you recommend for tracking? Tracking is a big problem. Cumulative effect is huge. What BMPs would you recommend for tracking?
Tracking Stabilized construction entrance, street sweeper for larger projects Broom for small jobs
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
Inlet Protection Inlet protection must be maintained in good condition Care must also be used when removing these MORE THAN ONE PERSON is needed
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
City of Westbrook MS4 O&M Training Erosion Controls Jute netting Check dams Straw wattle – staked in, of sufficient height March 24, 2016
Erosion Controls A big mess Silt fence with vegetated buffer – not right at the edge of the disturbed ground
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
Trash and Debris No liquids, not overflowing, not rusted out and leaking, ideally covered
Dust Control Sprayers – water NEVER OIL
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
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?
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
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
