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)

SSYC

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

K. Potter UW-CEE

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)
