SECTION C: Specifications/Drawings Project Location: Mojave National Preserve, San Bernadino County, southern California.

The contractor shall perform all work in accordance with the documents listed in Section J, which are attached and incorporated into this solicitation/contract. The work is a non-time critical removal action (NTCRA) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), 42 U.S.C. §§9601 et seq. The contractor will implement a previously developed Non Time- Critical Removal Action work plan (NTCRAWP) and Statement of Work (SOW) at Hidden Hill mine in Mojave National Preserve (MOJA), to remove mine tailings and commingled contaminated soil (“materials”) and transport them to appropriate disposal facilities.

The intent of the contract is to remove the materials to reach the removal action objectives (RAOs) at the site as confirmed by post-removal testing. RAOs address risk to human health and the environment, constraints on park resources, and federal and state regulations and guidance. The specific RAO for this site is to eliminate the potential for metals impacts to human health and the environment from copper in the mine tailings. The estimated removal quantities in this contract are based on previous site investigations and may have changed since the surveys. The contract uses unit-priced items subject to the variation in quantity clause in conjunction with an established ceiling to reach the Site’s RAOs.

F.1 Commencement, Prosecution, and Completion of Work The Contractor shall be required to (a) commence work under this contract within 10 calendar days after

52.252-2 FAR Clauses Incorporated By Reference (Feb 1998) This contract incorporates one or more Federal Acquisition Regulation (FAR) and Department of the Interior Acquisition Regulation (DIAR) clauses by reference, with the same force and effect as if they were given in full text. Upon request, the Contracting Officer will make their full text available. Also, the full text of a clause may be accessed electronically at these addresses:

FAR - FAR | Acquisition.GOV (https://www.acquisition.gov/browse/index/far) RFO - https://acquisition.gov/far-overhaul/far-part-deviation-guide DIAR - eCFR :: 48 CFR Chapter 14 -- Department of the Interior (DIAR) (https://www.ecfr.gov/current/title- 48/chapter-14) Clauses that are from the DIAR begin with “14”.

Addendum to 52.252-2: This procurement cites clauses and provisions from both the codified Federal Acquisition Regulation (FAR) and the Revolutionary Federal Acquisition Regulation Overhaul (RFO); RFO will be cited only for parts whose deviations have been adopted by the Department of the Interior.

https://www.acquisition.gov/browse/index/far https://acquisition.gov/far-overhaul/far-part-deviation-guide https://www.ecfr.gov/current/title-48/chapter-14 the date the Contractor receives the notice to proceed (NTP), (b) prosecute the work diligently, and (c) complete the entire work not later than 400 days thereafter. The time stated for completion shall include final cleanup of the premises.

The CO will issue the NTP after receipt and acceptance of performance and payment bonds, and authorize access to the site for reconnaissance after receipt and acceptance of relevant liability insurance certificates. The CO will issue an authorization to mobilize and commence on-site sampling and removal activities after NPS acceptance of Contractor’s post-award planning documents and any remaining subcontractors’ liability insurance certificates.

F.2 Variation in Estimated Quantity If the quantity of a unit-priced item in this contract is an estimated quantity and the actual quantity of the unit-priced item varies more than 15 percent above or below the estimated quantity, an equitable adjustment in the contract unit price shall be made upon demand of either party. The equitable adjustment shall be based upon any increase or decrease in costs due solely to the variation above 115 percent or below 85 percent of the estimated quantity. If the quantity variation is such as to cause an increase in the time necessary for completion, the Contractor may request, in writing, an extension of time, to be received by the Contracting Officer within 10 days from the beginning of the delay, or within such further period as may be granted by the Contracting Officer before the date of final settlement of the contract.

Upon the receipt of a written request for an extension, the Contracting Officer shall ascertain the facts and make an adjustment for extending the completion date as, in the judgement of the Contracting Officer, is justified.

Unit prices include all necessary labor to perform the work, lodging and per diem for workers, plus cost for materials, delivery, installation, insurance, applicable taxes, overhead, and profit.

The Government may, at its sole discretion, increase or decrease the quantities of unit-priced line items to accomplish the work. The Contracting Officer may unilaterally authorize increased quantities by written notice to the Contractor any time prior to demobilization from the Site, and for decreased quantities any time prior to final payment. Refer to paragraphs F.2 and G.1.

If occupational diseases are not compensable under those statutes, they shall be covered under the employer’s liability section of the insurance policy, except when contract operations are so commingled with a contractor’s commercial operations that it would not be practical to require this coverage. Employer’s liability coverage of at least $100,000 shall be required, except in States with exclusive or monopolistic funds that do not permit workers’ compensation to be written by private carriers.

H.9 Archeological Findings Petroglyphs, artifacts, burial grounds or remains, structural features, ceremonial, domestic, and archeological objects of any nature, historic or prehistoric, found within the construction area, are the property of and will be removed only by the Government. Should Contractor's operations uncover or their employees find any archeological remains, Contractor shall suspend operations at the site of discovery;

notify Contracting Officer immediately of the findings; and continue operations in other areas. Included with the notification shall be a brief statement of the location and details of the findings.
