March 7, 1974

Director, Safety Department
Florida Public Service Commission

Tallahassee, FL 32304

Dear Mr. Batten:

This responds to your letter of February 20, 1974, asking whether a particular riser assembly
manufactured by Robroy Industries complies with 49 CFR 192.123(b).

As you noted, in a letter to Mr. Thomas G. Giles, Marker Manager, Robroy Industries, we
indicated that the assembly casing is not a pipeline and, therefore, the requirements for corrosion
control are inapplicable to it. We added, however, that the casing's mechanical connection
between the enclosed plastic pipe and a steel fitting above the ground must comply with section

All of the Federal safety standards applicable to plastic pipe, such as section 192.123(b), must be
met with respect to pipe enclosed in the casing. This does not mean that the riser assembly itself
is governed by the same standards. Since we do not know the quality of insulation provided by
the casing, if any, we cannot determine whether its use would enable enclosed plastic pipe to
comply with section 192.123(b) in relevant situations.

If we may be of further assistance, please let us know.
