Mr. Howard E. Boller
General Superintendent
Eastern Shore Natural Gas Company
P.O. Box 615
Dover, Delaware 19901
Dear Mr. Boller:
This responds to your letter of April 18, 1975, regarding construction of a public road over an existing gas
pipeline. You ask what criteria should be used in determining whether the pipeline should remain in place or
be relocated.
The Federal gas pipeline safety standards in 49 CFR Part 192 (copy enclosed) for the design, installation, and
testing of pipelines would not apply to the existing pipeline unless it is replace, relocated, or otherwise
changed as a result of constructing the road. Standards for operation and maintenance of the pipeline in 49
CFR 192.613 and 192.703(b) would require, however, that the pipeline be evaluated for safety purposes as a
result of the road construction and appropriate remedial action taken, if necessary, in accord with those
sections.
The Federal safety standards would not require that the pipeline be relocated as a result of the road
construction. In determining what other protective measures may be necessary, you should consider the
types and magnitudes of all anticipated road construction. Various causes of external forces which you should
consider include: unstable soils, floods, movement by heavy construction or maintenance equipment, and
direct damage by construction equipment.
We trust this satisfactorily answers your inquiry.
Sincerely,
Joseph C. Caldwell
Director
Office of Pipeline Safety

EASTERN SHORE NATURAL GAS COMPANY
P. O. BOX 615
DOVER, DELAWARE 19901
April 18, 1975
Mr. Joseph Caldwell, Director
Office of Pipeline Safety
Department of Transportation
Washington, D. C. 20590
Dear Mr. Caldwell:
We have a section of pipeline which lies in a Class 3 location and operates at between 30 and 39% SMYS. This
pipeline is within the confines of the state highway right of way. We have received plans from the State
Highway Department indicating they are going to widen and change the location of this road with the result
that our pipeline will be under the new roadbed.
What criteria must we use in determining whether the pipeline can remain under the new roadbed or it must
be relocated?
Sincerely yours,
EASTERN SHORE NATURAL GAS COMPANY
Howard E. Boller
General Superintendent
