| The Basics of the Parks Rules | Update |
| The 1999 Regional Haze Rule (RHR) is aimed at fulfilling the national goal established by Congress in the 1977 amendments to the Clean Air Act: “the prevention of any future and the remedying of any existing impairment of visibility” in mandatory class I federal areas. The RHR Best Available Retrofit Technology (BART) Rule is aimed at implementing the RHR targets by cleaning up some of the oldest and dirtiest industrial plants that contribute to park haze. Prevention of Significant Deterioration (PSD) provision protects air quality in Class I areas from new sources emitting air pollution when the source resides in an area considered IN attainment of the national health standards. If the area was not in attainment New Source Review would apply instead of PSD. | The Regional Haze BART rule was finalized by EPA on June 15th, 2005. The AMC is very disappointed with the final rule which essentially leaves behind Congressional intent of cleaning up specific parks and wilderness air. The EPA turned a deaf ear to over 2,000 outdoor enthusiasts who expressed a desire for EPA to publish a strong and enforceable BART rule that addressed visibility at each Class I area. Keep up the drum beat and make your voice heard. |
