This guide provides direction for planning and managing smoke from prescribed fires to achieve air quality requirements through improved smoke management practices. The Guide applies to all prescribed fires, those started by managers or by nature throughout the Manti-La Sal National Forest. When planning and conducting prescribed fires on the Manti-La Sal, the Prescribed Fire Manager and Prescribed Burn Boss will meet the Clean Air Act Standards and the Air Quality direction in the Manti-La Sal National Forest land and Resource Management Plan. Prescribed fire managers will emphasize the safety of all personnel conducting the burn; the health, safety, and protection of the property of others that may be directly affected by the fire; and the avoidance of off-site adverse effects to public health and visibility. Smoke management on the Manti-La Sal will be considered in every prescribed fire plan. This guide addresses methods for avoiding or mitigating the adverse impacts of smoke on the public health, and visibility. The Prescribed Fire Manager and the Prescribed Burn Boss can use this guide to develop techniques to meet smoke management objectives for individual prescribed fires and assure that prescribed fire programs on Manti-La Sal National Forest will meet air quality objectives of the States SIP and the Forest, Land and Resource Management Plan. Prescribed fires can be used to control the amount of fuel consumed and the time, direction, concentration, amount, duration and rate of release of smoke from fuels on the forest. Wildfire, may eventually consume any untreated fuels, but may occur at in opportune time from the standpoint of environmental quality. Such was the case in Yellowstone National Park in 1988 when one million acres were consumed in one month. The prescribed fires should not aggravate existing atmospheric loading situations through poor timing or poor execution of burns. These smoke management guides are intended to assist resource managers in planning prescribed fires in a manner which will minimize air quality effects. The guides provide for coordination between units and various governmental agencies. Properly applied they also assure that the Manti-La Sal National Forest will comply with the National and State Clean Air Act regulations and Manti-La Sal Land and Resource Management Plan. Failure to follow the smoke guidelines and the prescribed fire scheduling and reporting procedures or failure to secure clean burning may result in fines, restrictions or the loss of the privilege to use fire as a tool in wildland management on the Manti-La Sal National Forest. The principles stated here apply to the use of prescribed fires on the Manti-La Sal National Forest for any purpose, including the reduction of hazardous slash from timber activity, precommercial thinning, road clearing, range vegetation improvement, wildlife habitat diversity improvement, the maintenance of ecological plant communities, and to reduce fire hazards around structural improvements and the urban interface.
