We deliver quality solutions with integrity and expertise, every time.

CGRS began in 1987 as an environmental consulting, compliance, and construction company providing industry and regulatory compliance expertise and services to owners and operators in the upstream and downstream petroleum industry.

Over time we have diversified to meet the ever-changing customer needs by becoming experts in Environmental, Refined Fuels, RNG/CNG systems, Oil & Gas, and Water and Wastewater.

We are always on the lookout for the next opportunity to help our clients succeed. We have evolved to offer a much wider range of services: Compliance inspection, testing and repairs; permitting; engineering/design; fuel-system design/build; leak detection; water-quality sampling and assessment; air emissions management; SPCC; and Reclamation and Material Management … just to name a few.

Our expertise is multifaceted; we have subject-matter experts in diverse yet synergistic areas and are truly a one-stop shop for our customers.
