SUMMARY OF WORK

PART 1 � GENERAL

1.1 WORK COVERED BY CONTRACT DOCUMENTS

PROJECT LOCATION:

The project location is the Lake Mead National Recreation Area. The site is located in Echo Bay developed area outside of Boulder City, Nevada.

EXISITING CONDITIONS:

The backwash pond is located to the east of the water treatment plant off Echo Bay Road. The pond system consists of an approximately 960 square foot pond with 28,000 gallons of storage capacity.

The water treatment plant performs routine backwashing through the system to remove accumulated particles and debris, helping maintain the efficiency of the filters. The backwash water flows east by gravity to the backwash water pond through approximately 85 feet of 6-inch PVC pipe and past a 6-inch flapper valve where it drops into the pond. There is a small continuous flow of water into the pond, and every time the water plant performs a cleaning, it sends approximately 1000 gallons of chlorinated water into the pond where it has time to slow down the outflow and dilute before flowing out through the overflow drain and pipe into the nearby wash to the southeast side.

The pond structure is approximately 32 feet by 30 feet and has a maximum depth of 4 feet. There is a layer of geotextile fabric and a single membrane liner layer. The liner was damaged and ripped apart and a large amount of sediment has settled on top of the liner layer. Many tall reed plants have grown through the liner and various other vegetation debris surrounding the pond have fallen in as well, such as tree branches and shrubs. The liner is secured by an anchor trench around the perimeter of the pond

(2 feet deep and 2 feet wide). There is an overflow drain in the middle of the pond and approximately

35 feet of piping to the outlet into the wash.

The project requires construction services to repair and remedy the current deficiencies to the existing operation of the Backwash Pond. Annual inspections from the State of Nevada have determined the damaged liner as being out of compliance with holes in the liner. The installation of new liner in the backwash pond will allow the water plant to discharge to the pond as the permit states keeping the facility within the regulations. The National Park Service will not have to be concerned with possible state enforcing a violation order for not meeting the requirements for groundwater protection and possible groundwater contamination issues.

LAKE � PMIS #248827 01 11 00 - 7

a. Kelly Wallace, Biologist: kelly_wallace@nps.gov

D. 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 rewashed 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, service trucks, etc. These

LAKE � PMIS #248827 01 11 00 - 8

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.

E. Post Washing Equipment 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 the list below. Please contact via email all members and coordinate designated representative for inspection:
