Default Re: Vermont BANS Felt Soled Wadding Boots

Here is an Email giving the decon procedures used by Vermont. Very thorough! I just wonder how much of an 8 hour day is consumed by decon, I certainly hope all of us fly fishermen will be this thorough in our personal Decon!


I will paste the disinfection example below – hopefully the formatting will not get too garbled.



This is just one example; we have separate protocols for disinfecting our electrofishing boats, and for sampling fish in rivers. Some of these are “best practices” instead of disinfection techniques – for example, when sampling multiple locations along a river, work from upstream to downstream (disinfecting gear between each location) as there is less likelihood of moving aquatic nuisance species into new areas that way.



One word of caution, the quaternary ammonia solution we use for disinfection is quite strong, and not something I would recommend for the general public unless they were very careful to contain the used solution so it didn’t run onto the ground or into the water.



Cheers,



Eric







Aquatic Nuisance Species Spread Prevention Plan

For Sea Lamprey Control Activities 2010 - 2015

Vermont Department of Fish & Wildlife

September 16, 2010



The follow document details equipment disinfection procedures designed to minimize the spread of Aquatic Nuisance Species (ANS), including pathogens, while performing sea lamprey control activities on Lake Champlain and its tributaries.



Full disinfection of equipment such as nets, waders, canoes, boats, trailers and motors will occur before moving between waterbodies. At the completion of all sea lamprey control activities equipment will be disinfected according to the techniques described below before it is moved to other bodies of water.



Upon leaving any waterbody:



· All Vehicles, boats, trailers, equipment, and all personal gear and clothing

- Visual inspection immediately after removing equipment from a waterbody.

- On-site removal of all plants, plant fragments, organisms, organic material, mud or other foreign materials.

- Remove all drain plugs and drain the bilge and well water.



Disinfection Techniques: The following techniques will be used on all equipment that will be moved between waterbodies.



1) Non-absorbent items (boats, canoes, water sampling equipment and other “hard” objects)



· Bleach Solution: soak or spray all surfaces for at least one minute in a 2% bleach solution (13oz or 1.5 cups of bleach added 5 gallons of water).



OR



• Quaternary ammonia: soak or spray all surfaces for at least one minute. When using SANICARE Quat-128™ manufactured by Buckeye International use 2.5 oz of Quat-128 for each gallon of water; or 250ml of Quat-128 with water added to make 10 liters.



OR



· Drying: All equipment will be dried for a minimum of 5 days before use on another waterbody.



OR



Pressurized Hot water: All equipment with be pressure washed for a minimum of one minute with water at a temperature at or above 140°F.


Note: small items like sampling vials may be washed in hot water and dish soap.



2) Absorbent items: (i.e. Life jackets, boots, waders)



· Bleach solutions are not recommended for absorbent materials due to ineffective penetration compared to quaternary ammonia solutions (surfactants).



· Quaternary ammonia: Equipment will be soaked for a minimum of 30 minutes to ensure disinfectant penetration. When using SANICARE Quat-128™ manufactured by Buckeye International use 2.5 oz of Quat-128 for each gallon of water; or 250ml of Quat-128 with water added to make 10 liters.



OR



· Drying: All equipment will be dried for a minimum of 5 days before use on another waterbody.



Note: Any boots with felt soles will be disinfected with quaternary ammonia.





Specific Boat Disinfection Procedures:



· Boat surfaces will be disinfected with a 2% bleach solution (1.5 cups of bleach per 5 gallons of water).

· If equipped with a livewell, insert standpipe and pour 5-gallons of 2% bleach solution in.

· Pour another 5-gallons of 2% bleach solution over the entire surface of the boat deck.

· Run any bilge or recirculating pumps for at least 10 seconds to pump bleach solution through pumps and hoses.

· Attach garden hose to motor muff and place muff over the water intake ports on the outboard’s lower unit. Turn on hose. Start outboard and run for at least 10 seconds to flush the motor coolant system with clean water.

· Remove any grates or screens covering water intakes for onboard tanks and remove visible debris/plant fragments. Clean grates or screens with garden hose.

· Insert garden hose nozzle into intake and flush with clean water. Run tank pump for at least 10 seconds to flush clean water through the tank pump hose.

· Remove stand-pipe from livewell and the bilge drain plug.

· Use garden hose to rinse the deck, bilge and any wells with freshwater. Flush for 10 minutes.

· Run any pumps with fresh water for at least 30 seconds to flush bleach solution.



OR



· Rinse boat deck, bilge, live well, boat hull and boat trailer with steam/hot water pressure washer with temperature set to a minimum of 140° Fahrenheit.

· Attach garden hose to motor muff and place muff over the water intake ports on the outboard’s lower unit. Turn on hose. Start outboard motor and run for at least 10 seconds to flush the motor coolant system with clean water.
