## Document text

<<<PAGE 1>>>

January 11, 1994
This is in response to your correspondence of September 17, 1993, requesting an opinion to
determine whether services provided by a particular contractor would subject their employees to
the drug testing requirements under Parts 199 and 40.
Your correspondence indicates that the contractor shall perform such functions as ultrasonic
testing techniques, radiographic test methods to include isotope or x-ray, liquid penetrate
examinations, and magnetic particle testing methods. Based on the information you provided, it
would appear that the contractor's employees would perform covered functions on a pipeline or
LNG facility that would subject them to the drug testing regulations.
Thank you for your inquiry. Please let me know if you need additional information about our
drug testing requirements.
Sincerely,
Richard L. Rippert
Drug Compliance Coordinator
