April 21, 1976
Mr. Richard B. Bender
Corrosion Associates
P.O. Box 11302
Fort Worth, Texas 76110
Dear Mr. Bender:
In your letter of March 31, 1976, you ask whether the exemptions contained in Section 192.455
apply to pipelines which were installed in an apartment project 20 years ago.
By its terms, Section 192.455 specifically applies to pipelines installed after July 31, 1971.
Likewise, Section 192.457 specifically applies to pipelines installed before August 1, 1971. This
distinction in the scope of the two sections indicates that the exemptions under Section 192.455
are intended to apply only to pipelines installed after July 31, 1971, and not to pipelines 20 years
old.
We trust this satisfactorily responds to your inquiry.
Sincerely,
\signed\
Cesar DeLeon
Acting Director
Office of Pipeline
Safety Operations
