Clayton Merrill Cell Phone: 702-371-7548

LAKE 317191 Page 7 of 46

Kelly Wallace Cell Phone: 702-371-9673

G. Equipment Washing:

1. Equipment washing is required to preclude the introduction and spread of non-native species into the Park. Therefore, all equipment shall be cleaned outside of the Park before entering the Park. Equipment leaving the park for any reason must be re-washed before returning to the job site. Equipment that is moved from the job site, but remains within the original developed area, need not be re-washed prior to returning to the job site. It is also known that there are areas inside the Park that have non-native plants and weed species infestation. Therefore, before equipment can be moved from one developed area to another, it must be washed at the location identified on the Site Plan (see attached site plan and mileage table) to ensure weeds are not spread from one developed area to another.

2. The Contractor shall clean all equipment prior to the equipment entering Lake Mead National Recreation Area. It is recommended that cleaning be accomplished by hot water, pressure washing, using water only. All equipment surfaces shall be cleaned, with special emphasis given to the undercarriage. This includes, but is not limited to:

wheel wells, bumpers, radiator grills, springs, shock absorbers, wire harnesses, skid plates, oil pans, axles, frame ledges, buckets, tracks, belly pans, etc. Cleaning shall also include all dirt and debris inside the cab, or operator area. A Shop-Vac or commercial car wash vacuum system may be used for operator compartments, provided the method used effectively removes all visible debris. Equipment cleaning is for the purpose of removing any seed and soil accumulations to prevent the potential spread of non-native plant and weed species from outside the park to locations inside the park. Cleaning shall be performed in a manner that will reasonably remove all visible soil, plant and other foreign material. All equipment that requires washing shall be inspected by government personnel, or contractors/partners assigned to this duty, to ensure compliance.

3. Equipment that requires washing is generally defined as track or rubber-tired machinery intended for use primarily off-road. Examples include backhoes, loaders, earthmovers, graders, rollers, bulldozers, water trucks, etc; or four wheel drive or passenger vehicles that are driven in off road areas. Equipment may also be stationary, such as a material screening plant, conex storage containers, or a mobile office (mobile offices may be cleaned in the same manner as operator compartments as outlined in paragraph 2). The equipment is generally under the direct control of the contractor or sub-contractors, is likely to remain on the construction site for an extended period of time, and may contain adhered soil and seed from other project sites.

4. Equipment/Vehicles that do not require washing are defined as those normally used for highway driving only, and travel primarily on paved surfaces and well maintained service roads and parking areas (this includes approved staging areas). Examples include semi-tractor trailers, dump trucks, concrete trucks, pickup trucks, fuel trucks, LAKE 317191 Page 8 of 46 service trucks, etc. These delivery and passenger vehicles are generally not under the direct control of the contractor, have no earth-moving function, and do not remain on the project site. These vehicles have a low probability of carrying adhered soil and seed from other projects. However, every vehicle and piece of equipment is subject to rejection from entering the park if there are obvious signs (covered in mud, plant material adhered to it, etc.) that it could be transporting non-native species into the Park.

H. Post Equipment Washing Inspections:

1. All equipment subject to inspection will be inspected by government, or other authorized personnel prior to leaving the paved surface or designated washing area identified on the Site Plan. Equipment determined to be free of soil or mud based on visual examination by government personnel will be cleared to enter the project area, or proceed to other areas of the park as appropriate. The Contractor shall arrange for needed inspections by contacting the NPS inspection office no less than 5 working days prior to the inspection. Such contact shall provide sufficient time to accommodate scheduling and travel to the site. Equipment not passing initial inspection must be rewashed outside the park at no additional expense to the government.

2. A list of government Inspectors for this project will be provided by:
