The Manual is prepared in two parts. Part I lists some of the industrial activities by their Standard Industrial Classification number and the equipment associated with the air pollution sources found in that activity. Part II illustrates the code numbers assigned to the equipment; two digit numbers representing control devices while the three digit numbers are assigned to the basic equipment. By definition, basic equipment is equipment from which the pollutant is primarily discharged. The basic equipment is further categoried by assigning a series of numbers according to the 'unit process' under which it may be found.
