The first of the contracts is a five-year $22m indefinite delivery/indefinite quantity contract to provide technical and outreach support services for the agency’s Science to Achieve Results (STAR) program.

The program encourages oil and natural gas companies to adopt cost-effective technologies and practices that improve operational efficiency and reduce methane emissions.

The second of the contracts is also spread over a five year term and is a $10m blanket purchase agreement to support the agency’s agricultural methane reduction programs to reduce emissions from livestock and agro-industrial by promoting the use of anaerobic digestion systems.

Tetra Tech’s Chairman and CEO Dan Batrack said, "The Natural Gas STAR and AgSTAR programs aim to help EPA and industry partners improve efficiencies, reduce emissions, and generate additional revenues through clean energy applications."
