Quick Summary
The U.S. Geological Survey (USGS) has issued an Intent to Award Notice for a sole source contract to Siskiyou County for precipitation sample collection at the NADP/NTN wet atmospheric monitoring station CA76 in Yreka, California. This notice serves to inform potential vendors that the USGS intends to award this contract without full and open competition.
Purpose & Scope
The USGS requires weekly site visits to collect, process, and ship precipitation samples, collect and transmit associated data, and perform routine instrument maintenance and repairs at the CA76 station. This effort supports the National Atmospheric Deposition Program (NADP) and National Trends Network (NTN).
Contract Details & Justification
This is an Intent to Award a sole source contract to Siskiyou County. The justification for this non-competitive award is that Siskiyou County owns the property where site CA76 is located and houses the sampling and laboratory equipment within a county building on their land. They do not permit third-party vendors access to the site or equipment, making them the only authorized and qualified source for collecting atmospheric deposition data in the Yreka, California area. The USGS is unaware of any other source that can provide these services.
Set-Aside
No set-aside designation applies to this sole source intent.
