Dear Mr. Hallmark:

This is in reply to your letter dated April 3, 1979. Your letter requests an interpretation of hydrostatic testing requirements for components set out in 49 CFR Part 195, ?195.304. You ask whether the 24-hour hydrostatic test period set forth in §195.302(b) applies to components such as pumps.

Please be advised that the 24-hour hydrostatic test period does not necessarily apply to components. Section 195.304(b) provides for exceptions to the 24-hour test period if the component is the only item being replaced or added to the pipeline system and if the component was hydrostatically tested at the factory or was manufactured under a quality control system that ensures each component is at least equal in strength to a prototype that was hydrostatically tested at the factory.

Inasmuch as the pumps you mentioned are apparently the only components being replaced or added and inasmuch as these pumps are hydrostatically tested at the factory; although not for a 24-hour period, please be advised that the requirements of §195.304(b) and §195.304(b((1) have been met.

Sincerely,

/signed/
