The U.S. Department of Transportation has scheduled three public meetings to discuss proposed changes in drug and alcohol testing rules for transportation workers.

Among other things, the proposed new rules would require labs to test all specimens for adulterations and substitution attempts. If tampering is discovered, it will reported as a refusal to be tested.
DOT also wants more mandated training for people involved in alcohol and drug testing and a "public interest exculsion" procedure that would prohibit the use of service agents that don't meet DOT standards. Another change would allow medical review officers to report positive test results to all employers of the person being tested, not just the employer that ordered the test.
The meetings are scheduled for March 20-21, Ronald Reagan Building and International Trade Center, Washington, D.C.; March 28, at the Hilton Los Angeles Airport; and March 30 at the Crowne Plaza, Dallas Market Center.
