 Plastic Piping Data 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 Database Committee, or PPDC. 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 (AGA), the American Public Gas Association (APGA), the Plastics Pipe Institute (PPI), the National Association of Regulatory Commissioners (NARUC), the National Association of Pipeline Safety Represenatives (NAPSR), the U.S. Department of Transportation (DOT) and its Office of Pipeline Safety (OPS).

Continued industry-wide participation is vital. We ask that your company seriously consider participation in this program.  Active participants have been recognized for their proactive actions.

This is a voluntary data collection effort. Contributed data elements will always be aggregated. No individual company will be identified with any specific data.

AGA directly receives the contributed data from the participating companies and inputs it into the database. No other organization, or member of the PPDC, may independently view or analyze the data. 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 montyly, and if in any month there are no reportable failures, participants are  asked to submit a "negative report."

Data submission also has been made easy. Data can be submitted in a variety of ways: by mail, electronically on diskette, or by fax. 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 purposes of the Operator Qualification Rule.
For data submission by fax, please return to fax number: 202-824-7136

The PPDC will use the information only in the aggregate. No member of the PPDC will be able to independently conduct a trend analysis of 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. 

If you are willing to participate, please complete and return the Volunteer Form. If you need additional information about the project, please contact: Kate Miller at (202) 824-7342 or
