There’s an app for that! In 2009, at our request, Tekk Innovations developed an iPhone application containing the federal pipeline safety regulations (49 CFR 40, and 190-199). It has keyword search and the capability to e-mail excerpts of the regulations to others. There have been several updates since the original app was released and was last updated on May 20, 2016. The app can be found in the iTunes store. The cost is $19.99.
Tekk Innovations has also developed apps for all the other CFRs, including all of 49 CFR for those who want all the transportation regulations, not just the pipeline ones; Louisiana Law, California Law and FAA FAR for Pilots.
Editor’s Note: I like the app with just the pipeline parts of 49 CFR, since I can search the pipeline regulations easier that way without getting hits from the other transportation regulations.
