This is in response to your correspondence of November 1, 1993, requesting an opinion to
determine whether the services that your company provides to pipeline operators would subject
your employees to the drug testing requirements under 49 CFR Parts 199 and 40.
You indicated your company’ s major function is to independently observe pressure tests of
pipelines that transport liquid or gas hydrocarbons and then to prepare and issue certified test
reports. These services include tests of both newly constructed pipelines and for periodical
testing of existing pipelines.
Your three questions and our responses are outlined below:
QUESTION: Can a contractor disclose the specific drug test results to the pipeline
company for whom it is performing services requiring drug testing under 49 CFR Part
199? If your answer to the above question is no, can our company disclose “statistical”
drug test results to a pipeline operating company?
ANSWER: Under 49 CFR Section 199.21, an operator is responsible for ensuring that its
contractors are in compliance with the drug testing regulations. To ensure compliance, the
regulation provides that an operator must be allowed access to the contractor’ s records, including
records relating to specific drug testing results. While Section 199.23(b) restrict disclosure of
information regarding specific drug testing results, the regulation does not apply to an operator
monitoring its “ employees” for purposes of compliance with the drug testing regulations. Thus,
an operator may require a contractor to provide specific drug testing information and statistical
data on those employees performing a covered function for the operator during the duration of
the contract.
QUESTION: Are our employees subject to drug testing in accordance with Part 199? Our
employees observe initial pressure testing of newly constructed pipelines and periodical
testing of existing pipelines. Initial pressure testing of newly constructed pipelines is a
required function under 49 CFR Parts 192 and 195. However, periodical pressure testing
(other than initial pressure testing) of existing pipelines is not required under Parts 192 and
195. A representative of the California Fire Marshal’ s Office presented an opinion letter,
dated April 10, 1990, prepared by your office which addressed the issue of witnessing “Live
Gas Test.”
ANSWER: Since new construction is exempted from the drug testing regulations the
observation of initial pressure testing by your employees would not subject them to the drug

testing requirements. Also witnessing a test for some reason unconnected with compliance with a
Part 192 operation or maintenance requirement would not subject an employee to drug testing.
Subpart J of Part 192 does address various test requirements when operators perform repair,
replacement or relocation of pipelines. Hydrostatic testing would involve operation of a pipeline,
maintenance of a pipeline, or the response to a pipeline emergency. Therefore, if such testing is
done to satisfy an operation or maintenance requirement of Part 192, such as checking the line for
leaks, then the employees performing the function would be subject to the drug testing
regulations.
An example might be, when a corroded pipeline section is replaced and hydrostatically tested as
required, the hydrostatic testing involves maintenance or possibly emergency response. As
another example, when a pipeline is hydrostatically tested to qualify it for operation at a higher
pressure, the hydrostatic testing involves operation of the pipeline.
Thank you for your inquiry. Please let me know if you need additional information about our
drug testing requirements.
Sincerely,
Richard L. Rippert
