Mr. Oliver J. Semmes, Jr.
City Engineer

P. O. Box 640
Gulf Breeze, Florida 32561

Dear Mr. Semmes:

This is in reply to your letter of November 6, 1970, requesting an explanation of the relationship
between Sections 192.619 and 192.621, of 40 CFR.

Section 192.619 establishes a maximum allowable operating pressure for all steel and plastic
pipelines. The requirements of Section 192.621 are additional requirements which apply to highpressure
distribution systems, defined in Section 192.3 as those systems in which the gas pressure
in the main is higher than the pressure provided to the customer.

Therefore, the two sections in question do not conflict. Both sections must be complied with
when operating high-pressure distribution systems in order to establish a maximum allowable
operating pressure.

You are correct in your view that if your line has not been operated at the new increased pressure
during the five years preceding July 1, 1970, you must follow the uprating or testing procedures
required by Part 192.

Thank you for your interest in pipeline safety.

Sincerely,

/signed/

Joseph C. Caldwell
Director, Acting
Office of Pipeline Safety
