Mr. Dean R. Moyer
Regulatory Compliance Administrator
Buckeye Pipe Line Company
P.O. Box 368
Emmaus, PA 18049-0368

Dear Mr. Moyer:

This responds to your letter of November 1, 1993, requesting that we better define the term "closure" in 49 CFR 195.124.

Closure as used in §195.124 is a device used for access to the interior of the pipeline system, including that used on hazardous liquid pipeline scraper launching and receiving vessels commonly referred to as "scraper traps."

The term "closure" also includes a blind flange. Such flanges may be constructed to meet American National Standards Institute B16.5 as provided in the ASME Boiler and Pressure Vessel code referenced in §195.124. The B16.5 code is an acceptable industry standard for the construction of a blind flange.

More comprehensive industry code requirements on closures can be found in section 406.6 of the American Society of Mechanical Engineers B31.4 Code.
