§ 32.230 - How and when must I identify workplaces?
(a) You must identify all known workplaces under each DOT award. A failure to do so is a violation of your drug-free workplace requirements. You may identify the workplaces -
(1) To the DOT official that is making the award, either at the time of application or upon award; or
(2) In documents that you keep on file in your offices during the performance of the award, in which case you must make the information available for inspection upon request by DOT officials or their designated representatives.
(b) Your workplace identification for an award must include the actual address of buildings (or parts of buildings) or other sites where work under the award takes place. Categorical descriptions may be used (e.g., all vehicles of a mass transit authority or State highway department while in operation, State employees in each local unemployment office, performers in concert halls or radio studios).
(c) If you identified workplaces to the DOT awarding official at the time of application or award, as described in paragraph (a)(1) of this section, and any workplace that you identified changes during the performance of the award, you must inform the DOT awarding official.
