WinDOT Documents

I love that the GPTC Guide and the PHMSA Enforcement Guidance are listed in the Table of Contents; so convenient.

Grouping of Documents

A major time-savings benefit of WinDOT is that related documents are grouped within each CFR code section for quick access. Clicking on those related documents opens them to their sections that are relevant to the currently selected federal code.

A good analogy would be opening an encyclopedia to a specific topic, and having it magically pull the other related books from the library shelves, and open them for you to the pages that are relevant to that same topic.

Examples of the related documents are interpretations, enforcement cases, guide materials, amendments, docket histories, FAQ's, drawings, permits, and many more.

The navigation and functionality is wonderful. Very user friendly.

Navigation Features

  • Code references are clickable links to the relevant section

  • Each Code Part is organized by an easy-to-use table of contents

  • Context sensitive glossary with inline definitions

  • Formatted for use from phones, tablets, and desktops

  • Print code sections directly to your printer

  • Cut and paste code sections into documents and emails

The search function is so much faster. I love it!

Powerful Search Features

With the sheer size of the Code Parts and the related materials, such as interpretations, waivers, alerts, and guide materials, a powerful search tool is important to help you save time, effort, and frustration locating the information you need.

WinDOT includes simple search features, as well as advanced Boolean search features with AND, OR, and AND NOT capabilities that make it easy to narrow the results to just the materials you need to assure safety and compliance of your pipelines.

ViaData continuously strives to provide a superior product with high levels of customer satisfaction.

History of the Regulations

Have you ever needed to know what the regulations were on on a date in the past? With the WinDOT History of the Regulations for Gas and Liquids, you can!


This subscription add-on from ViaData shows the complete text of all regulations after every amendment, back to 1970. It shows the old text in strikethrough, and the new text bold and underlined. Links to the final rules with preamble are included. 

This is a great research tool to assist your compliance programs, saving valuable time when researching the code changes and effective dates.

WinDOT would have saved me a week of research if I had purchased it sooner.

GPTC Guide

As an additional value, the Gas Piping Technology Committee Guide is included at no extra charge with subscriptions to the WinDOT Federal Gas Regulations.

The GPTC Guide provides operators with recommendations and references for complying with the federal gas pipeline safety regulations. The guide covers 49 CFR Parts 191 and 192 in detail, and dates back to 1970.

The GPTC is sponsored by the American Gas Association and is accredited by the American National Standards Institute. The committee meets 3 times per year to update the guide, and those updates are added immediately to WinDOT.

When I accepted the offer, I specifically said WinDOT had to be part of the package.

Technical Standards

With many technical standards incorporated by reference in the Code of Federal Regulations (and therefore federally enforceable), ViaData offers the option to purchase standards from these organizations:

  • American Gas Association

  • American Society of Mechanical Engineers

  • National Association of Corrosion Engineers

  • National Fire Protection Association

While priced similarly to other reseller options, the benefit of purchasing technical standards from ViaData is that they are delivered in the same user--friendly and feature-rich electronic manuals format as WinDOT, as opposed to PDF files.

Technical standards can be purchased separately from our subscription services, and you own the ones you buy for life, even if you are not a WinDOT subscriber.

WinDOT's functionality, ease of use and vast amount of information make it a must have for not only code and compliance engineers, but anyone involved in operating gas or liquid pipelines.

Always Up-To-Date

Daily monitoring for changes to federal and state regulations, related documents and guides is a key part of the WinDOT service that can save you a significant amount of work.

In addition, we offer our free Rapid Update Service to alert you proactively of any changes to federal and state regulations.


WinDOT is updated within one business day of any changes, and as a cloud-delivered service, you can feel confident that when you log in to WinDOT, you are using the latest information to maintain the safety and compliance of your pipelines.
