--Sole Source Justification

This contract represents the sole source award for the final phase (phase 4) of a multi-phase research project involving the Bureau of Land Management (BLM), United States Geological Survey (USGS), and PolyAnalytic Laboratory. The project focuses on testing soil palliatives to control dust at a solar energy facility located in Southern Nevada. The previous three phases consisted of developing the sampling methodology, conducting tests, and gathering related data, each managed under separate contracts. The continuation into this fourth phase suggests ongoing collaboration and the importance of consistency in testing methods and data collection across all project stages. The contract, identified by solicitation number 140L3918P0052 and posted in March 2018, falls under the NAICS code 541715, indicating research and development in the physical, engineering, and life sciences. It is managed through the Nevada State Office of the Department of the Interior, based in Reno, Nevada. Although certain details such as the place of performance and point of contact are not specified in the posting, the contract is part of the government's efforts to address environmental concerns related to dust mitigation at renewable energy sites. The sole source justification, which is not included in the public posting, further explains the necessity for awarding this contract without competition, likely due to the specialized nature of the work and the involvement of prior phases with the same research partners.
