The NPMS Public Map Viewer allows everyone, including the general public to view maps of Gas Ttransmission, Hazardous Liquid and Carbon dioxide pipelines, Liquefied Natural Gas (LNG) plants, and Hazardous Liquid breakout tanks in one selected county. Gas Distribution and Gas Gathering systems are not included in NPMS. Users are permitted to print maps of the data, but the data is not downloadable. Always call 811 before digging.

The Pipeline Safety Enforcement Program is designed to monitor and enforce compliance with pipeline safety regulations and confirm operators are meeting PHMSA expectations for safe, reliable, and environmentally sound operation of their facilities.

On this website PHMSA offers a variety of reports and records detailing its enforcement activity involving pipeline operators. These reports and records are offered on both nationwide and operator-specific bases and includes the following:
Nationwide Enforcement Activity - A high-level summary of PHMSA's overall enforcement activity.

Enforcement Actions - A summary of the various enforcement actions that have been undertaken by PHMSA.

Enforcement Case Status - The status of various types of enforcement cases by the year they were initiated.

Civil Penalty Case Status - The status of enforcement cases involving civil penalties.

Enforcement Information for Specific Operators - The national-level reports above are also provided on an operator-specific basis.

In the flagged files, PHMSA add data that are routinely used during data analysis and when presenting certain 20-year trends. Information includes: serious incidents (involving a fatality or injury requiring in-patient hospitalization), significant incidents (meet a number of predefined conditions, including inflation adjusted value of property damage, minimum threshold for volume spilled for hazardous liquid, fire and explosion for hazardous liquid), reported incidents (all pipeline incidents reported to PHMSA in accordance with reporting criterion which has changed over time), consequences (effects on both the general public and the pipeline industry), and state-based reports.

Series of Incident data and summary statistics reports produced which provide statistical information on incidents by type, year, geographical location, and others. The data provided is that from the Hazardous Materials Incident Report Form 5800.1

The Pipeline and Hazardous Materials Safety Administration has the primary responsibility for the issuance of DOT Special Permits and Approvals to the Hazardous Materials Regulations (HMR). A Special Permit or Approval is a document which authorizes a person to perform a function that is not currently authorized under the authority of the HMR. Also, in many instances, the Regulations require approvals and/or registrations prior to transportation in commerce. The Special Permits Search tool allows a user to search for active Special permits.

Title 49 of the Code of Federal Regulations (49 CFR Parts 191, 195) requires pipeline operators to submit incident reports within 30 days of a pipeline incident or accident. The CFR defines accidents and incidents, as well as criteria for submitting reports to the Office of Pipeline Safety. Specific information includes the time and location of the incident(s), number of any injuries and/ or fatalities, commodity spilled/gas released, causes of failure and evacuation procedures. The reports are used for identifying long- and short-term trends at the national, state and operator-specific levels.

A list of Significant Guidance documents, which include guidance document disseminated to regulated entities or the general public that may reasonably be anticipated to lead to an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or tribal governments or communities; create a serious inconsistency or otherwise interfere with an action taken or planned by another agency; materially alter the budgetary impact of entitlements, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or raise novel legal or policy issues arising out of legal mandates, the President's priorities, or the principles set forth in Executive Order 12866, as further amended.

PHMSA tracks Safety-Related Condition Reports (SRCR) and Integrity Assurance (formerly IM) Notifications submitted by operators to monitor the effectiveness of integrity programs and safety management systems before accidents, damages, or failures happen. PHMSA regulations include several exemptions from SRCR reporting. These exemptions limit the usefulness of SRCR as a leading indicator.
