APPENDIX B <br />AIR POLLUTION ABATEMENT STRATEGIES <br />Abatement strategies come into focus first at the construction phase <br />and then once again during the operational phase of an airport <br />project. The Airport and Airway Development Act of 1970 states it to <br />be "...national policy that airport development projects shall provide <br />for the protection and enhancement of the natural resources and the <br />quality of environment of the nation." To meet this objective, FAA <br />has published several advisory circulars dealing with airport <br />construction controls to prevent air and water pollution. <br />The first control discussed by the advisory circular to reduce air <br />pollution during construction addresses open burning. If the state or <br />local area where the project is located does not deal directly with <br />this, the following restrictions should be considered: <br />1. Do not permit tires, soils, asphalt, paint and coated metals in <br />combustible waste piles; <br />2. Do not permit burning within 1,000 feet of a residential or built- <br />up area or within 100 feet of standing timber or flammable growth; <br />3. Do not permit burning when prevailing winds are toward a nearby <br />town or built-up area; <br />4. Do not permit burning during local air inversions or other local <br />climatic conditions that would result in a pall of smoke over a <br />nearby town or built-up area; <br />5. Restrict the size and number of fires to avoid the danger of brush <br />or forest fires. <br />In some instances, one of the following alternatives may be <br />incorporated in lieu of open burning: <br />1. Spoil materials may be buried outside of airport construction <br />graded areas; <br />2. Wood may be salvaged for firewood or commercial use, such as <br />mulch; <br />3. Logs, brush, or other wooden materials may be removed to an <br />authorized disposal area or disposed of to the general public at <br />no charge. <br />The sources of air pollution during construction were listed in a <br />previous section. For each of the sources, abatement strategies exist <br />for reducing or eliminating the problem. The following strategies <br />exist for reducing or eliminating the problem. The following <br />strategies should be considered and evaluated relative to the type of <br />construction: <br />B-1 <br />
