Overview
Storm Water Permits for Marinas and Boatyards
No-exposure Certification
SWPPPs
Best Practices (BMPs)
Storm Water Pollution
Potential sources of pollutants to runoff in marinas and boatyards
• Material, equipment or boat storage
• Engine maintenance, winterizing
• Sanding, blasting, painting
• Pressure washing
• Fueling
• Waste handling and storage
• Vehicle parking
NPDES stormwater program The National Pollutant Discharge Elimination System (NPDES) Stormwater Program regulates stormwater discharges from:
• Municipal separate storm sewer systems
• Construction activities
• Industrial activities
Marinas and boatyards required to have a NPDES Stormwater General Permit or a No-exposure Certification:
SIC codes 3731 and 3732
- Ship and boat building and repair facilities
SIC code 4412 - 4499 (Marinas 4493)
- Water transportation facilities
WDNR Storm Water
General Permit (individual
permits rare for marinas)
NR 216 applies to all marinas, boatyards, boat contractors and builders
Municipal permits do not cover marinas and boatyards
If you or your boaters conduct maintenance, wash boats or store materials outdoors
First file a Notice of Intent form (3400-163); download the general permit and keep a copy for your files
Tier II General Permit fee is $ 130/yr; WDNR invoices and will renew automatically every 5 years
Requires a SWPPP and quarterly visual monitoring

No Exposure Certification • Excludes facility from the general permit
• Only if business does not conduct outdoor activities that could contaminate SW (boat maintenance, pressure washing)
• Materials or operations located in storm resistant shelter and are not exposed to rain, snow or runoff
• Shelter may be a roof only without sides if no contaminants released
• File WDNR Form #3400-188 self-assessment (no fee, pictures help)
• Granted on case-by-case basis; must be renewed every 5 years
Activities not requiring a storm resistant shelter
Drums, barrels, tanks and similar containers that are sealed e.g banded or otherwise secured and without operational taps or valves
Addition or withdrawal of material to or from containers while outdoors must not release contaminants
Open, deteriorated or leaking containers must be sealed, replaced or sheltered
platforms holding or containing drums must be contaminant-free
Above Ground Storage Tanks (ASTs) separate from boat maintenance, not leaking, preferably with secondary containment (impervious dike, berm or concrete retaining structure)
Lidded dumpsters, covered trash
Adequately maintained boats, forklifts, travel lift, trailers or other vehicles (not leaking or releasing contaminants); No junked boats or equipment if deteriorating
Storm Water Map Required for Clean Marina certification and WPDES Tier II General Permit
Facility map showing property boundaries, roads, buildings, paved areas, pervious areas (grass, gravel)
Note direction of storm water flow with arrows
Locate storm drain inlets and outfalls
Locate potential sources of contamination
Identify storm water treatment areas (ponds, infiltration, pervious pavement, rain barrels)

Storm Water Pollution Prevention Plan (SWPPP)
• Identify SWPP Team
• Site map with drainage areas
• Potential pollution sources
• Past spills & leaks (keep records)
• Identify non-storm (dry weather ) discharges
• Monitoring (visual) and training (keep records)
• Identify storm water BMPs: Source Protection BMPs
Area Specific BMPs to treat SW
Site-wide BMPs
Best Practices – The Key to Managing Runoff
1. Prevent pollution (Source Protection) - clean runoff can drain to surface and groundwater
2. Treat and discharge BMPs- polluted runoff cannot drain to surface and groundwater
Source contol BMPs
These BMPs help qualify you for a no-exposure certification
• Every site will be different
• BMPs need to be tailored to each situation
• This requires site analysis and design
Analyze the site
Best done when its raining
Sources of Runoff
• Off-site runon from streets, adjacent property, streams
• Roof drains and sheetflow
• On-site contributing areas (materials and activities)
• SW Map needed
• Slope - Flat (or not)
• Soils
• Proximity to Water
• Impervious Pavement leading to water
Challenges
Source Control BMPs • Store materials and equipment out of the weather • Locate work areas away from water • Educate boaters
Source Control BMPs Cover work areas and storage areas Buildings Shed Roofs Moveable covers
Source Control BMPs
Contain dust from sanding - use tarps and vacuum sanders; collect debris
Prohibit spray painting outside of shop, use rollers & brushes
Restrict sanding or painting over water

Source Control BMPs
Spill containment and roofs for fueling stations
Capture and Treat Storm Water Onsite Minimize the amount of impervious surface
Intercept and redirect runoff
Slow down runoff allowing settling
Treat or decrease amount of pollutants through settling, filtration, & bio-degradation
Use soil erosion control practices during construction

Use pervious surfaces
Pervious Asphalt Avoid Coal Tar Sealants
Where to place BMPs? Stormwater runs off down hill
BMPs
Up-gradient BMPs Reduced treatment volume Lower discharge elevation Reduced downstream runoff
Where to put BMPs?
Implementing Stormwater BMPs
Marinas present challenges
• High value frontage
• Diverse activity
• Flat
• Low elevation
• Diffuse drainage
• Proximity to surface waters
Preferred Management Options
“An ounce of prevention” – Pollution Prevention through Source Controls • Avoid contact between rainfall and equipment,
fueling and work areas • Cover work and storage areas • Train for best material management practices Capture and treat Storm Water • Utilize roof water, or convey to surface waters • Direct off-site, infiltration through porous surfaces,
vegetated swales, rain gardens • Treat remaining “dirty” runoff (biofiltration, wash
water treatment, proprietary devices)
