Amendment 1 transmits Attachment 3, Clarifications (4 pages), which augments the Statement of Work, Work Plan, and solicitation and includes a list of site visit attendees. This acquisition is for a Non-Time Critical Removal Action (NTCRA) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) at the Hidden Hill Mine contaminated site within Mojave National Preserve (MOJA) in California. It is set-aside for Indian Small Business Economic Enterprises (ISBEEs) in accordance with Department of the Interior Acquisition Regulation (DIAR) 1480. SITE VISIT: A group site visit is scheduled at 10:00 am on 4/9/26. Pertinent details are in Section L of the solicitation. Attendance at the site visit is strongly encouraged (not mandatory). Requests for individual site visits will not be honored. DESCRIPTION: The site is a relatively small and remote abandoned mine located on approximately five acres and is at an elevation of approximately 3,400 feet above sea level. The work includes removing approximately 69 CY of comingled tailings and potentially affected underlying material (assuming a thickness of approximately one foot) that are distributed over an area of approximately 1,850 sf. Including any ancillary soils which may become commingled during excavation activities, approximately 100 CY (conservative estimate, includes underlying/commingling) are estimated for the purpose of this Removal Action. Applying a conversion factor of 1.5 tons per cubic yard, NPS estimates 150 tons of material will be excavated, transported, and disposed in the removal action (RA). The work also includes preparation of post-award plans (Site Health and Safety Plan (SHASP), Under-an-Acre Pollution Prevention Plan (UPPP), Traffic Control Plan (TCP), Hazardous Material Spill Plan (HMSP), and Confirmatory and Waste Sampling and Analysis Plan (SAP)), characterizing the material, transporting it to appropriate disposal facility/ies, collecting and analyzing confirmation samples, and preparing a Response Action Completion Report (RACR). The estimated removal quantities are based on previous site investigations. The firm fixed price contract will use a combination of lump sum and unit-priced items subject to the variation in quantity clause in conjunction with an established ceiling and notification requirements. Additional details will be provided in the documents to be posted with the solicitation. A payment bond (100%), performance bond (100%), and liability insurance will be required prior to contract performance.
