facilities such as concrete batch plants, which combine aggregate, cement, and other ingredients to produce concrete, that are subject to air and water quality regulations similar to those for aggregate production and processing operations. The term "aggregate production operations," often abbreviated to "APOs," is frequently used

Aggregate Production Planning (Sales and Operations Planning (S&OP)) Sales and Operations Planning is: • prepared for product families (i.e. products with similar labor, material or processing requirements); e.g., passenger tires. • in aggregate terms such as total units (e.g. Camry [s), standard labor hours or dollars.

sieve is called "fine aggregate" or "sand," and larger aggregate is called "coarse aggregate." Coarse aggregate may be available in several different size groups, such as 19 to 4.75 mm (3/4 in. to No. 4), or 37.5 to 19 mm (1-1/2 to 3/4 in.). ASTM C 33 ("Standard Specifications for Concrete Aggre-
