CDH Consulting air quality staff work closely with our clients to plan for upcoming development and modifications to existing operations so that development is not delayed by the air permitting process. Our staff has decades of combined emissions permitting/registration and compliance experience at the federal, tribal, and state levels. Understanding timelines and obligations associated with pre-construction, production, and modification permits and registrations are key to operational planning and cost management. We remain active in industry working groups and monitor agency activities to maintain up-to-date knowledge of the regulations and trends affecting your business.
