On April 8, 2010 the long-awaited proposed DFARS clause on minimizing the use of hexavalent chromium from DoD contracts was published in the federal register. Written comments to the proposed rule will be accepted until June 7, 2010.
The published proposal differs in several potentially important ways from the draft last reviewed by Army ESO in the fall. The significant differences are discussed below:
1) The prohibition in sec. 223.7302 simplifies the language by stating that the prohibition for deliverables or the use of hexavalent chromium, shall be “in contract performance” rather than “during sustainment phases of a system.”
2) For legacy systems the revised language states that alternative “shall” (vice “should”) be considered during system modifications, …
3) The exception for “barium chromate based corrosion inhibitors” has been eliminated.
4) The prohibition language to be placed into contracts not only prohibits any “deliverables” from containing hexavalent chromium, but also prohibits contractors using such materials in performance of the subject contract. This clause would seem to then prohibit the use of hard chrome on DoD weapons systems without explicit approval.
