is crushed; when compacted, dolomite fines facilitate the
hardening of the roadbed.
The concrete aggregate sold by petitioner is a washed
dolomite ranging in size from 5/16" to 3/4" in diameter. It is
used, together with water, fine aggregate (usually sand), and
cement, as an ingredient in concrete. During the years at issue,
only the Merriam quarry, of all of petitioner's quarries, had
washing facilities.
The utility and bedding rock sold by petitioner is dolomite
ranging in size from 3/4" to 4" in diameter, with smaller sizes
included in the product. Some dolomite fines are included, but
not to the extent they are included with road base. Utility and
bedding rock is used as a base for concrete pipe or PVC pipe,
especially sewer pipe.
The rip rap sold by petitioner consists of dolomite used for
erosion control, especially around waterways. Petitioner sells
rip rap as small as 4" to 9" in diameter, but also in a small
boulder size, 24" in diameter and sometimes larger. The aglime
sold by petitioner is a fine, pulverized dolomite material,
crushed to a size generally no larger than a grain of white rice,
which is used to neutralize soil acidity and to provide magnesium
to soil compositions. The red ball diamond aggregate sold by
petitioner is identical to aglime in size and composition but,
unlike aglime, always has a red color. Petitioner's customers
used this product as a ball diamond surface.
