Regional Haze Program and RH SIP Submittals
Many of America’s national parks and wildlife areas are known for their amazing vistas. The Regional Haze Program is a long-term national program designed to protect current visibility conditions at treasured areas that have been designated by EPA as federal Class I Areas, and to restore visibility to natural conditions at those impacted by man-made sources.
Oklahoma’s 2010 Regional Haze State Implementation Plan (RH SIP) has begun to restore and protect visibility at the Wichita Mountains Wilderness Area (WMWA) and at other Class I areas that may be affected by Oklahoma emissions. The WMWA, Oklahoma’s only federally-designated Class I area, is located within the Wichita Mountains National Wildlife Refuge in Comanche County, near Fort Sill & Lawton, OK. It is managed by the U.S. Fish and Wildlife Service.
