Clean all vehicles and equipment to remove all visible traces of soil, plant material, debris, and petroleum from wheels, tires, tracks, drive mechanisms, undercarriages, etc. before entry into Yellowstone National Park. Follow applicable Federal land management agency requirements and state requirements. Maintain cleaning and inspection records. Only materials and equipment free of toxic pollutants may be placed within wetlands and waters.

All equipment and tools for tree work including tree removal shall be cleaned completely prior to entering and leaving the work zone to prevent the spreading of non-invasive plant seeds. Ensure equipment and tools are pressure washed with hot water (greater than 102 degrees F) between locations and prior to entering the park.

All vehicles and equipment will be inspected by NPS personnel before their entry into the

Park for mud, weeds, and other unwanted substances. Contact the Yellowstone Veg Management team (Monday through Thursday only) a minimum of 48 hours before entry to allow for inspec-tion (see Equipment Inspection Contact List included in specification package).

Contactor to provide the CO documentation in writing that decontamination of equipment was completed following the parameters shown in this specification.

Decontaminating equipment conveying water or coming in contact with waters within the

Park: Decontaminate equipment including water tanks, pumps, hoses, excavators, etc. be-fore entering Yellowstone National Park. If equipment is transferred from one watershed to another it must first be decontaminated again according to this Subsection.

1. Clean the exterior surface of all equipment transporting or coming in contact with wa-ter by pressure washing with a minimum of 3000 pounds per square inch at 125 °F.

2. Pressure wash with hot water the interior of all tanks, hoses and equipment to eliminate dirt, debris and organic matter prior to disinfecting.

3. After pressure washing is complete, perform disinfection process with a chlorine/water solution of 200 parts per million (ppm) chlorine and allow to stand in the tank a mini-mum of 12 hours. Use water for the disinfection process from a potable municipal source. Obtain CO approval of the water source. Use either powder (calcium) or liquid (sodium) hypochlorite as follows:

a) 0.5 fluid ounce of household bleach sodium hypochlorite per gallon of water produces a 200-ppm solution.

b) Example: For a 4000-gallon truck, (4000 gallon x 0.5 fluid ounce = 2000 fluid ounce) = approximately 16 gallons of bleach required.

c) 0.044 ounce of 65 percent available powder calcium hypochlorite per gallon of water also produces a 200-ppm solution. Calcium hypochlorite is commonly used as swimming pool chlorine. Example: For a 4000-gallon truck, (4000 gal-lon x 0.044 ounce = 176 ounces) = 11.00 pounds of powder required.

YELL 338223 01 10 00 - 8

d) Mix additional 200 ppm solution and fill pumps, hoses, etc. and allow to stand a minimum of 12 hours. Take a sample and test it to verify the 200-ppm require-ment is met.

e) Open the distribution bar of the truck to allow chlorinated water into all parts of the system. Take a sample and test it to verify the 200-ppm requirement is met.

Do not discharge chlorine-water solution into any body of surface water. Legally dispose of the chlorinated water outside of the Park.

Use water drawn from one body of water only within that watershed; do not transfer water to another watershed. If a truck or equipment is transferred to a different extraction site, or is transferred between watersheds, it must first be decontaminated again according to this subsection. Cover the intake hose of pumps with a fish protection screen when pumping and use an intake float, structural frame, or other acceptable means to keep the intake point off the bottom to prevent mud from being disturbed or collected.
