The purpose of the Arkansas Smoke Management Program (SMP) is to assure adherence to air quality standards and to manage smoke from prescribed fire to keep the smoke’s impact on people and the environment within acceptable limits. In 1997, the Environmental Protection Agency (EPA) reported that fine particles (2.5 micrometers or smaller) have the potential to significantly impair human health when people are exposed to high levels. The fine particles that can impair human health can also reduce visibility in federally mandated Class I areas such as Caney Creek Wilderness Area and Upper Buffalo Wilderness Area where the United States has established a goal to make reasonable progress at removing any human impairment of visibility. An estimated 70 percent of the particulate matter emissions in smoke are fine particles. Therefore, prescribed fire should follow these guidelines to limit public safety hazards posed by smoke intrusion into populated areas, prevent deterioration of air quality, prevent National Ambient Air Quality Standards (NAAQS) violations, and protect visibility impairment at Class I areas and other smoke-sensitive areas.
