## Document text

<<<PAGE 1>>>

October 3, 1983
Odorization of Gas, Section 192.625
James C. Thomas, chief
Southern Region, Pipeline Safety, DMt-16
Richard L. Beam, DMT-30
Robert L. Paullin, DMT-10
Your memorandum of September 14, 1983, indicates the need for further information to respond
to my cases 1, 2 and 3.
Assume that the source line is transmission or non-rural gathering and that it is "legally
unodorized" because it meets the provisions of either 192.625(b)(1) or (3) but not (b)(2). I trust
this information will be sufficient to respond to cases 1, 2 and 3 which concern "one customer"
pipelines.
If the type of ultimate consumer does influence your responses to cases 1, 2 and 3 (as suggested
in your final paragraph), I request guidance as to how to distinguish between "large volume
customer: and, for example, an industrial or farm tap customer.
