3 HOW DOES BOAT WASHING FIT? VOLUNTARY GUIDELINES TO PREVENT THE SPREAD OF AQUATIC INVASIVE SPECIES THROUGH RECREATIONAL ACTIVITIES November 2012 Purpose of guidelines: Consistent, practical, and effective guidance to communication and outreach efforts Take into account key pathways, vectors, and life history of all AIS, including fish, aquatic plants, invertebrates and pathogens Support, not supersede local, state or tribal laws Promote voluntary actions to support the national Stop Aquatic Hitchhikers! campaign as well as statewide efforts such as Clan Boats, Clean Waters

4 HOW DOES BOAT WASHING FIT? VOLUNTARY GUIDELINES TO PREVENT THE SPREAD OF AQUATIC INVASIVE SPECIES THROUGH RECREATIONAL ACTIVITIES November 2012 Recreational Equipment Decontamination A key concept for recreational equipment decontamination is that the effectiveness of the treatment depends on the activity and the type of AIS. Bottom Line: Hot water kills AIS, while rinsing, flushing or high pressure washing removes them.

5 SCENARIO 1: If aquatic recreational equipment has been left in the water for less than a day, key actions to prevent the spread of all AIS are: Inspect and clean off any aquatic plants, animals, and mud from all equipment before leaving a water access Drain water from livewell, and other water containing equipment Dispose of unwanted bait, worms, and fish parts in the trash Don t move live organisms from one water body to another

6 SCENARIO 1 (cont.): The intent of those actions is to clean off any visible large-bodied organisms attached to or in watercraft or recreational equipment so that what remains are small-bodied organisms, which are easily rinsed off or die out of water in a short period of time. To this end, added precautions that improve treatment effectiveness are to: Spray/rinse recreational equipment with high pressure hot water to clean off mud and kill aquatic invasive species, AND/OR Dry everything for at least five days before reuse or wipe briskly with a towel if complete air drying is not possible before reuse Rinsing recreational equipment is an effective way to clean off species not visible to the naked eye.

7 SCENARIO 2: If aquatic recreational equipment has been left in the water for more than a day, the following decontamination methods are recommended: Spray/rinse hull and other external areas or recreational equipment with high pressure (2,500 psi) hot water (140 o F for 10 sec) Rinse/flush motors with hot water (120 o F) for 2 minutes Rinse/flush interior compartments with hot water (120 o F) All equipment surfaces exposed to surface water, especially if left in the water for more than a day on invasive mussel infested waters should be decontaminated. Young invasive mussel settlers are difficult to see with the unaided eye, but on smooth surfaces they feel like sandpaper.

8 EITHER SCENARIO: After the initial removal of aquatic plants and animals at the water access, follow these steps: Spray/rinse recreational equipment either at home or at a car wash unless state, tribal or local regulations prohibit leaving the site without washing. Inspect, clean and rinse first, while higher temperature and pressure will speed up treatment and improve efficacy. Basically, rinsing is good, but using hot water is better. Generally, residential hot water heaters are set at 120 o F. However, temperatures at the nozzle will be lower because of the water s heat loss to pipes, hoses, ambient temperature, etc. Commercial car washes typically use water pressure of no more than 1,500 psi and car washes rarely have water hotter than 100 o F. If recreational equipment is heavily bio-fouled, certified decontamination services are highly recommended and may be required based on local, state, or tribal regulations.

9 SUMMARY Recommended actions for day users are: inspect, clean off, drain, rinse (with low pressure, hot as possible) and dry for more than five days. For recreational equipment left in zebra mussel infested waters for more than a day, do all of the above, except use high pressure, hot water for exterior surfaces, and low pressure hot water for interior components.
