Dear Mr. Ives:
This responds to your letter of May 6, 1976, concerning "set back" rules for gas pipelines in the
proximity of occupied housing.
Under the Natural Gas Pipeline Safety Act of 1968, the Michigan Public Service Commission
has adopted and enforces the Federal gas pipeline safety standards (49 CFR Part 192) against
intrastate gas pipeline within the Commission's jurisdiction. The Federal standards do not
contain "set back" rules, but do, however, provide for adequate safety through other types of
requirements which increase in stringency depending on the proximity of a pipeline to occupied
areas. At the same time, the Michigan Commission may impose additional or more stringent
safety requirements.
Sincerely,
Cesar DeLeon
Acting Director
Office of Pipeline
Safety Operations

Dear Mr. Furow:
The attached private gas transmission line is being presently constructed in the county road right-
of-way through a rural area. As far as I can determine there are no set back rules in terms of
existing structures. The pipeline will have an anticipated operating pressure of 400 pounds and
falls about 20 feet from my basement. It appears to fall even closer to other houses along the
right-of-way. To the best of my knowledge they have complied with Michigan's safety code.
However, it is my feeling that in the proximity of occupied housing a conduit should be installed
and vented. Otherwise there should be some set back rules particularly in heavy clay areas.
Does the Federal Government have any set back rules on constructions of this kind or are such
matters left up to the state authorities?
Sincerely,
Robert E. Ives
