Statistics and Trends

While a small portion of the Pipeline Safety Division's findings lead to formal enforcement actions, the Pipeline Safety Division thoroughly investigates all methods and practices of pipeline companies, including reports, records and other information to evaluate compliance with state and federal regulations.  The voluntary cooperation of the pipeline company to provide the Pipeline Safety Division with full and open access to the operator's premises and records is essential to the effective operation of gas safety enforcement inspections. For this reason, inspection records and accident reports where a formal enforcement action has not been initiated are not made public.  Aggregated data is available on the U.S. Department of Transportation Pipeline & Hazardous Materials Safety Administration's (PHMSA) website.

Data Submissions

Each year the Commission’s Pipeline Safety Division enters into an agreement with the U.S. DOT Pipeline and Hazardous Materials Administration (PHMSA) to enforce the federal pipeline safety regulations.  As such, PHMSA audits the Pipeline Safety Division each year.  The PHMSA annual program evaluation is a review of the State agency’s pipeline safety program.  It includes an examination of State agency policies, plans, records, and procedures of the previous calendar year as well as the observation of the field inspection of a pipeline operator.
