                           TITLE 46--SHIPPING
 
         CHAPTER I--COAST GUARD, DEPARTMENT OF HOMELAND SECURITY
 
PART 16--CHEMICAL TESTING--Table of Contents
 
                  Subpart B--Required Chemical Testing
 
Sec. 16.230  Random testing requirements.

    (a) Marine employers shall establish programs for the chemical 
testing for dangerous drugs on a random basis of crewmembers on 
inspected vessels who:
    (1) Occupy a position, or perform the duties and functions of a 
position, required by the vessel's Certificate of Inspection;
    (2) Perform the duties and functions of patrolmen or watchmen 
required by this chapter; or,
    (3) Are specifically assigned the duties of warning, mustering, 
assembling, assisting, or controlling the movement of passengers during 
emergencies.
    (b) Marine employers shall establish programs for the chemical 
testing for dangerous drugs on a random basis of crewmembers on 
uninspected vessels who:
    (1) Are required by law or regulation to hold a license issued by 
the Coast Guard in order to perform their duties on the vessel;
    (2) Perform duties and functions directly related to the safe 
operation of the vessel;
    (3) Perform the duties and functions of patrolmen or watchmen 
required by this chapter; or,
    (4) Are specifically assigned the duties of warning, mustering, 
assembling, assisting, or controlling the movement of passengers during 
emergencies.
    (c) The selection of crewmembers for random drug testing shall be 
made by a scientifically valid method, such as a random number table or 
a computer-based random number generator that is matched with 
crewmembers' Social Security numbers, payroll identification numbers, or 
other comparable identifying numbers. Under the testing frequency and 
selection process used, each covered crewmember shall have an equal 
chance of being tested each time selections are made and an employee's 
chance of selection shall continue to exist throughout his or her 
employment. As an alternative, random selection may be accomplished by 
periodically selecting one or more vessels and testing all crewmembers 
covered by this section, provided that each vessel subject to the marine 
employer's test program remains equally subject to selection.
    (d) Marine employers may form or otherwise use sponsoring 
organizations, or may use contractors, to conduct the random chemical 
testing programs required by this part.
    (e) Except as provided in paragraph (f) of this section, the minimum 
annual percentage rate for random drug testing shall be 50 percent of 
covered crewmembers.
    (f) The annual rate for random drug testing may be adjusted in 
accordance with this paragraph.
    (1) The Commandant's decision to increase or decrease the minimum 
annual percentage rate for random drug

testing is based on the reported random positive rate for the entire 
industry. All information used for this determination is drawn from the 
drug MIS reports required by this part. In order to ensure reliability 
of the data, the Commandant considers the quality and completeness of 
the reported data, may obtain additional information or reports from 
marine employers, and may make appropriate modifications in calculating 
the industry random positive rate. Each year, the Commandant will 
publish in the Federal Register the minimum annual percentage rate for 
random drug testing of covered crewmembers. The new minimum annual 
percentage rate for random drug testing will be applicable starting 
January 1 of the calendar year following publication.
    (2) When the minimum annual percentage rate for random drug testing 
is 50 percent, the Commandant may lower this rate to 25 percent of all 
covered crewmembers if the Commandant determines that the data received 
under the reporting requirements of 46 CFR 16.500 for two consecutive 
calendar years indicate that the positive rate is less than 1.0 percent.
    (3) When the minimum annual percentage rate for random drug testing 
is 25 percent, and the data received under the reporting requirements of 
46 CFR 16.500 for any calendar year indicate that the positive rate is 
equal to or greater than 1.0 percent, the Commandant will increase the 
minimum annual percentage rate for random drug testing to 50 percent of 
all covered crewmembers.
    (g) Marine employers shall randomly select a sufficient number of 
covered crewmembers for testing during each calendar year to equal an 
annual rate not less than the minimum annual percentage rate for random 
drug testing determined by the Commandant. If the marine employer 
conducts random drug testing through a consortium, the number of 
crewmembers to be tested may be calculated for each individual marine 
employer or may be based on the total number of covered crewmembers 
covered by the consortium who are subject to random drug testing at the 
same minimum annual percentage rate under this part or any DOT drug 
testing rule.
    (h) Each marine employer shall ensure that random drug tests 
conducted under this part are unannounced and that the dates for 
administering random tests are spread reasonably throughout the calendar 
year.
    (i) If a given covered crewmember is subject to random drug testing 
under the drug testing rules of more than one DOT agency for the same 
marine employer, the crewmember shall be subject to random drug testing 
at the percentage rate established for the calendar year by the DOT 
agency regulating more than 50 percent of the crewmember's function.
    (j) If a marine employer is required to conduct random drug testing 
under the drug testing rules of more than one DOT agency, the marine 
employer may--
    (1) Establish separate pools for random selection, with each pool 
containing the covered crewmembers who are subject to testing at the 
same required rate; or
    (2) Randomly select such crewmembers for testing at the highest 
percentage rate established for the calendar year by any DOT agency to 
which the marine employer is subject.
    (k) An individual may not be engaged or employed, including self-
employment, on a vessel in a position as master, operator, or person in 
charge for which a license or merchant mariner's document is required by 
law or regulation unless all crewmembers covered by this section are 
subject to the random testing requirements of this section.
