It is shown that the divergent cross sections in the calculation of parton production can be regulated self-consistently without an {\it ad hoc} cut-off, and that the resultant parton production and transverse energy production rate are finite. Consequences on the energy density estimates are discussed.10 pages, REVTeX, 5 ps-figures uuencodedHigh Energy Physics - PhenomenologyNuclear Theorytext
