Civil Engineering & Environmental Permitting

To address the growing needs of our clients, Keystone expanded its engineering services related to the development of oil and gas sites in 2012. The engineering practice has grown to more than 20 civil engineers and five biologists supporting projects for gas production, midstream, transmission, distribution, and land developments. These developments generally involve the construction of improvements such as access roads, well pads, pipelines, and impoundments, along with supplemental facilities. The Keystone Engineering and Environmental team provides all civil engineering, natural resource, state, and federal permits necessary to construct these facilities. The team has outstanding relationships with the State and Federal regulatory agencies and has a thorough understanding of the requirements. Keystone also provides construction compliance services for as-built, construction quantities, and environmental compliance.
