ASC GPTC Z380 – Gas Piping Technology
The Gas Piping Technology Committee (GPTC) is accredited by the American National Standards Institute (ANSI) as an Accredited Standards Committee (ASC) and is designated Z380/GPTC. The Committee developed and maintains the ANSI Z380.1, Guide for Gas Transmission, Distribution, and Gathering Piping Systems (The GPTC Guide).
The GPTC Guide contains information and some “how to” methods to assist the operator in complying with U.S. DOT Pipeline Safety Code Title 49 – Part 191 and Part 192.
GPTC members include persons with expertise from the natural gas transmission, distribution and manufacturing fields as well as from federal and state regulatory agencies.
The American Gas Association, an ANSI-accredited Standards Developing Organization (SDO), serves as the secretariat to GPTC.

More About The Committee
The Committee has approximately 100 members, 40 of which have voting rights and are known as the Main Body.
The GPTC is structured as follows:
- Main Body: Voting group of record, responsible for final approval of Guide Material.
- Divisions: Review work product of the Task Groups and moves it forward to Main Body consideration. The three Divisions are:
- Transmission
- Distribution
- Manufacturers
- Task Groups: Develop new Guide Material or revise existing material. The four Task Groups are:
- Design and Construction
- Damager Prevention / Emergency Response (DPER)
- Operations and Maintenance / Operator Qualification (O&M/OQ)
- Integrity Management Plan / Corrosion (IMP-Corr)
Member Commitments:
Members are required to attend all meetings. If you can not attend a meeting then notification must be provided in advance. Failure to routinely attend meetings is a reason for membership termination. Therefore, members must commit themselves to travel expenses for three meetings per year. Meeting attendees are also required to pay a meeting registration fee to cover committee expenses.
