Building or repairing a pipeline is a major effort, and the last thing you want to worry about is compliance with a maze of environmental rules and regulations, looking for bird nests or wildlife on the right-of-way or rescuing a snake in the trench. DRG Environmental can perform all these tasks and more, from pre-construction surveys for wildlife, nesting birds, desert tortoise, weed and rare plants to environmental training for your crews, biological monitoring during construction and post-construction restoration with native plants.
