The design and inspection of septic systems falls under the auspices of the Environmental Complaints and Local Services Division of the Department of Environmental Quality, which has offices spread across the state.Environmental programs manager Matt Pace says the agency works closely with the Oklahoma Certified Installers Association (OCIA), founded in 2000 when its executive director, Bill Warden, retired from his job as DEQ’s onsite coordinator.
