Mr. Terry M. Winter
Director
Engineering and Construction
San Diego Gas and Electric
P.O. Box 1831
San Diego, CA 92112
Dear Mr. Winter:
This responds to your letter of September 30, 1992, in which you ask if the Federal
pipeline safety regulations address the issue of proximity of people and buildings to a
pipeline.
The pipeline safety standards in 49 CFR Part 192 govern the design, construction
operation and maintenance of gas pipelines nationwide in environments varying from
highly populated to rural. The regulations establish a class location scheme for gas
pipelines based on population density in proximity to the pipeline. The regulations include
more stringent requirements for greater population in proximity to the pipeline. A pipeline
designed and operated in accordance with these requirements will protect the safety of the
public.
Sincerely,
Cesar De Leon
Director, Regulatory Programs
Office of Pipeline Safety
