Show May 1, 1971* Basically, the assignment of the committee was to establish air quality standards and develop a comprehensive plan for prevention, abatement, and control of air pollution in the State of Utah. The basic processes by which the goal of cleaner air could be attained in Utah are as follows: ( 1) Determine what foreign elements are in the air and the concentration of each; ( 2) Determine where these elements come from; ( 3) Determine how they can be controlled; and ( k) Develop appropriate standards and regulations and suitable compliance measures for accomplishing the goal. A " source inventory" to determine the source and amount of pollutants has been completed by the Utah Division of Health using procedures recommended by the U. S. Air Pollution Control Administration. These data are contained in Division of Health Report dated May 1, 1971* and updated in their report dated April 1972.^ 55 Figure B- 6 shows the percentage of various pollutants discharged into Utah's air ( State as a whole) and percentage of total air pollutants discharged by each source classification ( State as a whole). Table B- 12 shows the total emissions inventory summary in tons for the year 1970 for Area 1 which includes the Wasatch Front counties. Similar data on a county basis for Area 2, which includes the remainder of the State, are available in the reports referenced above. Sufficient data, however, are not available to show the rate of increase of air pollution although it is quite apparent that increase is occurring, especially along the Wasatch Front. For comparison, Table B- 13 shows the total emission summary in tons for 1970 for the entire State, the Wasatch Front area, the proposed Bonneville Unit area, and the Uinta Basin ( Duchesne and Uintah Counties). Agricultural Chemicals a. General The 12- county area within the Central Utah Water Conservancy District contains over 21 million acres, of which about 805,000 acres are farmed. The remaining 20.2 million acres are forest or range lands. Present use of pesticides on the forest and range lands is not known. Present use of agricultural chemicals is carried out more or less on a limited basis but is dictated by the types of agriculture practiced in each area or subarea as described . below. 203 |
