PRICE SUBMITTED BY: Signature Phone Vendor Name FAX Address Email SECTION C--DESCRIPTION/SPECIFICATIONS/STATEMENT OF WORK C.1 SCOPE OF CONTRACT Description of Work: The intent of this contract is to have a contractor divert Upper Truckee River (UTR) flows during implementation of the UTR Reach 5 Restoration Project and install dewatering BMPs in the upland areas surrounding the project area in 2016. First option (option 1) includes, approximately 2,170 ft of temporary river bypass be put in place which includes temporary coffer dams, pumps and pipe to accommodate stream flows of 30 cfs (with an additional 10 cfs capacity to accommodate a potential storm event). Second option (option 2) includes, installation of coffer dams and 2,170 ft of gravity fed pipes. Next, the contractor must install upland dewatering basins in the locations shown on the plan sheets provided. Finally, a second river diversion/bypass approximately 3,055 ft in length must be put in place before the first diversion is removed. The second diversion would be smaller in size, needing to accommodate stream flows of 15 cfs (with an additional 5 cfs capacity to accommodate a potential storm event). In addition, we are asking the contractor to provide us (USFS Staff) with the equipment necessary to operate a discharge water spray field in the dewatering basins. Contractor Responsibility: The Contractor shall provide all equipment, supplies, transportation, labor, and supervision--necessary to complete the project, except for that which the contract clearly states is to be furnished by the Government. C.2 Project Location & Description Location: The project is located on National Forest and California Tahoe Conservancy land just south of South Lake Tahoe, CA in El Dorado County under the direction of the Lake Tahoe Basin Management Unit (LTBMU). Description: Access to the work site will be from 2 locations, across the Lake Tahoe Airport runway and on Highway 50/89, across from Jewel Rd and South of the Lake Tahoe Airport. * Exclusions (non-work areas): *Construction fencing will be in place to protect the non-work areas. Accessibility: * Access in the work area will be on a combination of surfaces including; across the airport runway and on a temporary road constructed by the LTBMU on crane mats, encapsulated roadway, steel plates and native meadow surfaces through the project area meadow. Any prospective contractor desiring an explanation or interpretation of the solicitation, drawings, specifications, etc., must request it in writing from the Contracting Officer soon enough to allow a reply to reach all prospective contractors before the solicitation closing date.

C.4 Estimated Start Date & Contract Time Start: 07/11/2016 and stay in place until 10/15/2016 Time: Approximately 14 weeks. See also Section F C.5 Restrictions on Work. Work may be performed at any time during the period of the contract, except as outlined here. Nothing in this part shall be construed to take away any of the Government's rights under the Suspension of Work Clause (52.242-14). Restrictions are as follows: 1. In accordance with the fire plan, if included in Section J. 2. When the Contracting Officer (or designated representative) determines that adverse weather has made access too dangerous or that continued vehicular travel would cause unacceptable road damage. 3. Scheduled setup and removal of all equipment and supplies will be limited to 7am to 6pm Monday thru Friday. 4. If delays are needed for complete removal of aquatic organisms from the existing channel. C.6 Licenses and Insurance The contractor shall obtain the insurance and licenses listed here; (see also Section L, Notices to Offerors and Respondents). MSPA Card (Form WH510): This contract [ ] does [ x ] does not require the contractor to be registered with the US Department of Labor as a Farm Labor Contractor. The Contractor shall provide a current Form WH510 or legible copy. Other: NONE C.7 Camping and Housing Camping is not permitted in US Forest Service campgrounds. Contractor [ ] will [X] will not be permitted to camp elsewhere on US Forest Service land. Camping on Forest Service land is not a right; permission may be revoked for failure to comply with the terms of the permit. (See also Section H, Camping Permit Compliance) C.8 Technical Requirements 1) The entire flow of the Upper Truckee River (UTR) must bypass the Project site by way of two separate diversions. The Contractor will install temporary dams on the UTR sufficient to capture all stream flow as well as two back to back downstream dams at the bottom of the project to control backwater. - By July 11th, stream flow is expected to be 30 cfs or less for the 1st diversion (D-1), pumps and piping will be used (option 1). Under the option 1 scenario, an additional 10 cfs capacity will be required to accommodate a potential storm event. If flows are higher than expected, at the LTBMU's discretion the contractor would install the temporary dams and piping, and the LTBMU would initiate a gravity diversion option rather than pumping (option 2). D-1 will be put in place starting the week of July11, 2016 and stay in place for 5-7 weeks. - The 2nd diversion (D-2) will be installed late enough in the season that flows are expected to be 15 cfs, this diversion will be pumped and piped. An additional 5 cfs capacity will be required for this diversion to accommodate a potential storm event. D-2 will be installed approximately Aug 22, 2016, and stay in place for 4-6 weeks. - Both water diversions must operate 24 hours a day until end of contract terms (or an earlier date specified by the LTBMU). - Contractor will be responsible for installation of all instream flow dissipaters at the outlet of each diversion. Contractor shall provide specifications for flow dissipaters for LTBMU approval. 2) Sound attenuation is required on all pumps and motors used on the project site. 3) Scheduled setup and removal of all equipment and supplies will be limited to Monday through Friday from 7am to 6pm. 4) Security fencing/personnel will be required around all vulnerable pumps and equipment to insure dewatering/diversion is not interrupted and resources are protected. - Contractor shall provide a contingency plan in the event of system failure. 5) Contractor will be allowed two weeks starting no earlier than 07/11/2016 to install and activate the first diversion system. - Access for installing the first diversion will be provided through/across the Lake Tahoe airport runway (which will require a designated vehicle escort) and along a temporary access road constructed by the LTBMU on the meadow surface. o The number of trips into the site across the airport runway shall be minimized to the extent feasible. - Timing of 1st Diversion (D-1) installation will depend on river flows, anticipated to be approximately July 11th. - The 1st diversion (D-1) will need to be left in place until after the 2nd diversion (D-2) is installed. 6) Exact timing of the 2nd diversion installation is currently unknown, however the contractor will be provided 2 week notice prior to activating the diversion to establish the dam and divert full UTR flows. 7) For both diversions: - The diversion dam installations and removal shall follow the guidance provided in the design plans and the technical specifications. - The LTBMU will pump and discharge water encountered within the dewatered reach of the river while the diversion is in place (i.e. groundwater seepage). - The LTBMU will conduct aquatic organism salvage and removal in the existing channel during each diversion installation, which must be completed prior to full diversion activation. o Metered flows into the channel downstream of the coffer dam would be required to maintain some flow for aquatic organism salvage, and to conduct channel flushing. For the pumped diversion(s), a wye fitting shall be installed near the upstream end of the diversion pipes. o During this time, the diversion system will be required to be tested for leaks before full channel diversion. o Contractor will need to coordinate closely with the LTBMU during aquatic organism salvage and relocation efforts, and possibly will need to delay the full river diversion to enable the crew to get the remaining organisms out of the river prior to diverting the entire river flow. - For protection of aquatic organisms and to prevent the spread of aquatic invasive species and pathogens: o All equipment and vehicles used in a waterbody during project implementation shall be inspected and free of invasive species prior to implementation. o Use screening devices for water drafting pumps to avoid impacts to aquatic species. o Ensure that field gear (waders, float tubes, etc.) is cleaned, decontaminated, and/or fully dried prior to entering or moving between aquatic habitats. o To minimize the risk of spreading potential aquatic pathogens and/or diseases through aquatic systems, all field gear (footwear, nets, etc.) that comes in contact with water shall be disinfected using a 0.016% solution of quaternary ammonia. 8) Contractor will be responsible for construction/installation and demobilizing of the Upland Dewater Basin (per sheet C-5 of the engineering plans and technical specifications). Upland Dewater Basin North (3.4 acres) and Dewater Irrigation Cell 6 (1.8 acres) will be required. Upland Dewater Basin North and Dewater Irrigation Cell 6 will be constructed immediately after installation of the first diversion (D-1) and completion of access road construction. Impermeable barrier fence (or approved equivalent) will be installed at the downslope perimeter of each of the Dewatering areas. 9) The contractor will be responsible for removal of both diversions and coffer dams at the completion of project activities in each respective area. Timing of removal of each diversion will depend on project progress. The contractor will be provided 1 week notice prior to needing each diversion demobilized. 10) The contractor will provide all the equipment necessary for our staff to assemble and operate a spray field in the dewatering basins. Items needed would include two 25yd filter boxes (which we could attach our 6" pump to), 300' of 6" alum pipe, 6" manifolds, six sprinklers on tripods (50-75gpm each), and 1500' of hose to supply the sprinklers. 11) Quotes should include make and model numbers for all mechanical equipment proposed for use to accommodate the flow capacities described above for each diversion.
