Plastic Pipe Database Collection Initiative

A group of representatives of federal and state regulatory agencies and the natural gas and plastic pipe industries have come together and formed The Plastic Pipe Data Collection Initiative. Their goal has been to create a national database of information related to the in-service performance of plastic piping materials. Members include the American Gas Association, the American Public Gas Association, the Plastics Pipe Institute (PPI), the National Association of Regulatory Commissioners, the National Association of Pipeline Safety Representatives (NAPSR), the U.S. Department of Transportation and its Office of Pipeline Safety.


Continued industry-wide participation is vital. Participants have been recognized for their proactive actions, and we ask that your company consider participation in this important, voluntary data collection effort. Contributed data elements will always be aggregated, and no individual company will be identified with any specific data.

HOW TO VOLUNTEER: Access the volunteer form here

HOW TO SUBMIT DATA: PPDC submission forms can be accessed here. They can then be submitted in a variety of ways:

  1. Email to 
  2. Fax to 202.824.7136
  3. Electronically on a CD or thumb drive. Mail to AGA, Attn: Debbie Ellis.
  4. Hard copy. Mail to AGA, Attn: Debbie Ellis.

Regardless of the form that is used, or the way in which the data are submitted, the information can be entered into the AGA-secure database and confidentiality can be preserved. The collection of this data is not a "covered task" for Operator Qualification (OQ).

AGA inputs data into the database unpon receival from participating companies. No other organization, or member of the PPDC, may independently view or analyze the data. The PPDC as a group will review the data for trends and patterns, ensuring the use of uniform and scientifically sound statistical approaches. Of course, AGA cannot assure that the aggregate data would not have to be shared in the unlikely event of a subpoena or valid order to produce it to a competent authority.

Because the project mission is to gather data on plastic material failures, contemporaneous failures caused by third-party excavation activity are not reported. Participating companies would report instances of third-party damage discovered through post-failure analysis of the piping. The PPDC has designed a unique data collection form to facilitate the process. However, the data can also be collected using your company's existing failure report forms. Participants are asked to report monthly, and if in any month there are no reportable failures, participants are asked to submit a "negative report."

The PPDC also compiled historical plastic piping manufacturer information.  This ongoing effort is maintained by Plastics Pipe Institute and helps to identify the manufacturers of pipe, fittings and appurtenances for plastic gas distribution operations, including material designations, when the materials were produced, size ranges and other important information.  Corrections and/or additions are encouraged and should be communicated to PPDC c/o Gerianne Cain at PPI (  It should be noted that operators are required to install piping that meets current regulations.
