determination of the causes, chemical com position, quantity, and means for control of motor vehicle contaminant emissions Carries out research and evaluates advanced vehicu lar propulsion systems for air pollution con trol potential Division of Process Control Engineering conducts an engineering research and de velopment program directed toward identifi cation and control of pollutants discharged to the atmosphere by industrial, commercial, or domestic processes Designs, operates, and monitors contract research on prototype and demonstration control methods and equipment Conducts field evaluations and stimulates demonstration studies de signed to promote control ofstationary sources of pollution Bureau of Abatement and Control, under this division, conducts technical and adminis trative activities necessary to implement federal air pollution abatement responsi bilities Provides for the development and strengthening of state, regional, and local air pollution control programs through grants-maid and technical assistance to air pollution control programs and industry Develops and administers a national motor vehicle pollution control program to insure adherence to federal standards, the adequacy and effec tiveness of control devices, systems, and in spection programs for the control of air pol lution from automobiles Department of the Intenor 18th, 19th, and C Sts NW , Washington, D C 20240 Bureau of Mines Promotion of safe, healthful working con ditions in the nation's mines and mineral processing plants has been a major responsi bility of the Bureau of Mines since its creation by the Congress in 1910 The demands of mineral conservation over the years have required gradual broadening of bureau activ ity in such important research fields as mining, metallurgy, and fuels technology Progress m industrial techniques and equipment has required continual expansion and improve ment of bureau health and safety programs This work can be classified under research, education and training, testing of equipment. and coal mine inspection Each of these activities is described below Research Fundamental and applied re search, devoted to health and safety problems m such fields as rock physics, explosives and explosions, and mine ventilation, has con tributed to noteworthy improvements in methods (a) for supporting ground at mine workings, (b) for preventing ignition of combustible gases, liquids, and coal dust, and (c) for planning and installing effective and reliable systems for coursing air through underground workings Bureau research has defined the limits offlammability for hundreds of fluids and vapors, and has determined with precision the conditions under which many different kinds of dust will explode It has also led to advances in mine fire fighting, in underground lighting systems, m tunnel design, and in design of safer mining methods and equipment Education and Training On the basis of knowledge acquired through research and exhaustive investigation of thousands of accidents, the bureau has developed effective courses in accident prevention, first aid, and mine rescue Supplemented by the pub lished findings of its many studies and by such widely used handbooks as its First Aid Manual, these courses have instilled safety awareness and competence in emergencies in millions of mineral-industry workers The bureau also promotes safety by active sponsor ship of the Joseph A Holmes Safety Associ ation (named for the bureau's first director), the National Safety Competition, and the biennial National First Aid and Mine Rescue Contests Testing of equipment Research, fre quently conducted in cooperation with industry, also has provided the basis for many of the ngorous tests developed and given by the bureau to equipment and accessones designed for use m mining and related fields Bureau standards are used in evaluating the permissibility for underground use of items ranging from respiratory protective devices to continuous-mining machines and dieselpowered mining equipment Bureau testing is done at the request of equipment manu facturers who pav standard fees for the service and are permitted to display the bureau seal 347
