  The Steenrod operations (mod p) in Chow theory are defined for any prime p
for a quasi-projective scheme, without appealing to the results of any domain
but Milnor's K-theory. The new definition also gives a direct formula that
depends only on the scheme itself. Additionally, basic properties of the
operations are proved from the new definition. The idea is based on a
construction of M. Rost.
