The incumbent team of INTERA and Navarro Research and Engineering appears likely to split up on the National Nuclear Security Administration’s follow-on contract for environmental characterization and remediation at the Nevada National Security Site, WC Monitor has learned. The team has held the contract since 2009 as Navarro Nevada Environmental Services, LLC. The current contract is set to expire in September, 2014, and the NNSA late last week released a draft Request for Proposals for the follow-on small business procurement. Both Navarro and INTERA declined to comment yesterday on the split.
