ATTACHMENT #1 - REQUIRED MITIGATIONS

For the proposed project actions to be within compliance requirements during construction and/or project implementation, the following mitigations must be adhered to.

Air Quality

• Cover all haul trucks carrying construction materials or debris.

• Control dust by periodic water sprinkling.

Fires

• If construction requires the use of spark or flame producing equipment in the summer months, contact the Fire Management Office for a hot work permit.

Night Sky

• Lighting shall not be permitted to adversely affect views of the night-sky. Any lighting replaced during this project will be dark sky compliant.

Park Operations & Management

• Provide coordinates of new or relocated NPS infrastructure, including solar array and leach fields to the GIS/ Data Management Office upon project completion. Contact the GIS Coordinator at 559- 565-3725 for more information.

• Contractors will develop a Safety Plan and Transportation Plan and share this with the National Park Service for comment and compliance with park health and safety regulations 30 days prior to any construction activities.

• If proposal includes new radio frequency use, frequencies must be verified non-interfering to public safety communications by SEKI Telecom.

Rare, Threatened & Endangered Species - Fisher

Common to All Projects o Avoid habitat modifications or disturbance-causing activities within potential or high-quality denning habitat or within 370 acres of known active natal or maternal dens during the LOP.

o Store food and anthropogenic garbage in park-approved containers so fishers cannot obtain it.

o Ensure construction fencing allows for the safe passage of fishers and does not cause entrapment.

o Teach work crews how to identify a fisher and den trees before work begins. Instruct them to contact dispatch immediately if a fisher is seen in or near the project site. If a fisher is spotted within a construction site, work should cease until the animal moves on without harassment. If a fisher is spotted in a potential den tree, work will cease, and the wildlife biologist will be contacted. The wildlife biologist would contact USFWS for further guidance.

Human Developments and Infrastructure o Retrofit pipes, water tanks, and other such structures with capping, screening, and escape ramps to avoid entrapment of wildlife.

o Maintain or remove old tanks, pipes, and irrigation canals.

o Avoid expansion of footprints of existing development in suitable fisher habitat. Do not install new developments in high quality fisher habitat.

SEKI – 200843 01 11 00 - 8

Vehicular Strikes o All project staff would follow posted speed limits but will reduce their speed by an additional 5 mph during dawn and dusk.

o All project work would begin at least 30 minutes after dawn and end at least 30 minutes before dusk unless special permission is given. In the case night work is approved, all lighting would follow NPS lighting guidelines.

o As feasible, rapidly remove road-killed wildlife from roads in suitable habitat so fishers are not killed while feeding.

Noise Disturbance o Through the third week of April, when the highway typically opens to the public, work crews would be dispersed, when possible, to reduce noise disturbance.

o Equipment to be used prior to the third week of May would be limited to hand tools, dump truck, and backhoe.

Soundscapes

• Consider noise effects when scheduling project work. Construction is only allowed between 8 am to 6 pm, Monday through Friday, excluding all Federal Holidays.

Visitor Use & Experience

• Consult with SEKI's Public Affairs Office at a minimum of 3 weeks prior to project work to allow adequate time for public notification.

Vegetation - Exotic Plants

• The unpaved staging area may need to be treated for non-native plants pre-project and monitored post project. Please contact Rich Thiel as early as possible to determine whether pre-project or post project treatment or monitoring will be needed.

• Pressure wash equipment to remove all dirt and plant parts before entering the park for the first time, paying special attention to undercarriage and grill/radiator; subsequent entries will not require pressure washing unless the vehicle shows signs of mud, plant material, or other substances. Project manager will inspect equipment for compliance prior to entry into the park and reject equipment that is not adequately clean.

• Inspect, remove, and properly dispose of invasive plant seed and plant parts found on clothing, boots, tools, and camping equipment. Disposal consists of removing the seed and plant parts from clothing and equipment at a spot near the infestation or bagging the seeds and plant parts and disposing in bagged garbage.

• Materials must come from an approved source. Consult with the senior invasive plant ecologist at least a month in advance of project work.

• Before moving vehicles or equipment to a new job site, visually inspect and clean the vehicles or equipment (including the undercarriage) thoroughly to remove all mud, dirt, and plant parts.

6. All pricing and production rates within the estimate must be based on fair and reasonable pricing and cannot include a built-in contingency.

B. Labor:

1. The contractor shall estimate the cost of labor by itemizing each craft involved, indicating worker hourly rate (base rate + labor burden + fringe benefits) for each, and itemizing hours required for each craft directly engaged in modification work. Any work proposed requiring overtime work or premium pay shall be itemized separately. Rates shall be in accordance with the Davis-Bacon Act as incorporated herein. Labor Burden may include payroll taxes, Social Security, unemployment insurances, workers compensation insurance, Federal Insurance Contributions Act (FICA), FUTA, and other direct costs resulting from Federal, State, or local laws.

2. Itemize labor costs for equipment operators separate from equipment costs.

3. Labor costs for foremen shall only be costs for related work required for the modification.

C. Materials:

1. The estimated cost for materials shall include quotes from multiple sources. Material prices shall include applicable fees and credits, including but not limited to, sales tax, freight and delivery charges, and tax rebates.

2. No markup shall be applied to any material provided by NPS.

D. Equipment:

1. Equipment used for the project must be appropriately sized for the work being performed.

2. Do not include costs for "miscellaneous tools and equipment", in your proposal for a replacement value of $500 or less. Costs shown in excess of $500 shall be broken out separately.

3. Regardless of ownership, rates to be used in determining equipment rental costs shall be the lowest cost from one of the following sources:

a. United States (U.S.) Army Corps of Engineers, Ownership and Operating Expense

Schedule (use the latest edition and applicable region)

b. Construction Blue Book

c. Local equipment rental rates, documented by actual invoice charges, or itemized vendor quotes.

4. Estimated equipment rates shall include operating costs of all fuel, oil, lubrication, supplies, small tools, necessary attachments, ground engaging components, tires and tracks, routine repairs, and maintenance (cost of major repair and overhaul is not allowed per Federal Acquisition Regulation (FAR) 31.105(d)(2)), depreciation, storage, insurance, and all incidentals. Mobilization, if applicable, may be included for equipment solely used on the modification work but must be listed separately.

SEKI – 200843 01 26 01 - 5

5. Estimate full rate for equipment only for the duration that equipment will be utilized to accomplish work of the modification.

6. Standby unit rates are used in accordance with paragraphs 1.3, D, 2, above. If the U.S.

Army Corp of Engineers is utilized then their standby rates prevail. If Bluebook or local equipment pricing is accepted, then 1/2 of equipment costs minus any operating costs, major repair, and overhaul will be accepted.

7. If equipment is in standby mode due solely to a documented NPS delay, an established standby rate shall apply from the first day of the delay.

8. Equipment not used and on the job site for up to five consecutive days may be classified at standby rates, provided the equipment is or has been used solely to perform work on the modification and will be necessary to complete additional modification work. Equipment still on the job site but not in use after five consecutive days will not be considered in the modification pricing.

9. Requests for compensation for equipment stand-by time must be justified, documented, and itemized separately.

10. The estimated timeframe (daily, weekly, monthly) for use of the equipment must reflect the lowest cost to the Government.

E. Establishment and Application of Overhead and Profit Percentages:

1. Home Office Overhead and Profit (OH&P) shall be applied to direct costs only. Profit shall not be applied to overhead amounts, and overhead shall not be applied to profit. Home office overhead shall contain only allowable, allocable, and reasonable costs per the contract documents and FAR Part 31. Profit percentages are based on risk factors found in FAR Part 31which have been applied to the specific type of work included in this project.

Negotiated rates shall not exceed the following percentages for OH&P for contractor self-performed work:

Overhead………………8% Profit………………..…8%

2. The total aggregate limit of markup (OH&P) for Contractor and Subcontractors on modification work shall not exceed 25%. The NPS will not be responsible for the allocation of percentages between contractors and subcontractors at any tier.

3. If Contractors form a partnership, the partnership may only receive home office overhead and profit in the same amount as an individual Contractor (refer to paragraph 1.3, E,1 above). It is the responsibility of the partners to decide on the division of revenue.

4. Combined Increases and Decreases: On proposals involving both increases and decreases in the Contract Price, overhead and profit mark-ups are required on net increases and deducted on net decreases.

5. At no time can profit be calculated on Overhead or itself, it must be calculated on direct costs of work only.
