A recipient other than an individual is in
violation of the requirements of this part if the
Secretary of the Treasury determines, in writing,
that—
(a)
The recipient has violated the requirements
of subpart B of this part; or
(b)
The number of convictions of the
recipient's employees for violating criminal drug
statutes in the workplace is large enough to
indicate that the recipient has failed to make a
good faith effort to provide a drug-free
workplace.
