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 Noexposure 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) http://dnr.wi.gov/topic/stormwater/industrial/forms 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) Instructions on WMA Clean Marina webpages/resources

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 Photo from Indiana Clean Marina Guidebook
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 Egg Harbor Marina (JJR Smith Group) Quarter Deck Marina Photos by Vicky Harris

Treatment BMPs - Roof Water Rain Gardens Rain Barrels Cisterns
Use pervious surfaces POROUS PAVERS AIR EXCHANGE TEMPORARY STORAGE INFILTRATION AGGREGATE SUBSOIL K. Potter UW-CEE Voids between pavers filled with gravel or grass
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)
