State Pipeline Safety Policy
National Association of Pipeline Safety Representatives (NAPSR)
The National Association of Pipeline Safety Representatives (NAPSR), established in 1982, is an organization of state agency pipeline safety managers who are responsible for the administration of their state’s Pipeline Safety Programs.
State pipeline safety agencies
The map below is linked to state agencies responsible for pipeline safety, just click on the state you are interested in.
See the table below the map for information about the level of oversight each state has chosen for involvement in natural gas and hazardous liquid pipeline regulation. The Pipeline and Hazardous Materials Safety Administration also tracks state-by-state regulatory information, and those links can be found through our state-by-state information link here.
State pipeline safety authority
Under federal law, states may choose three different levels of involvement in natural gas and hazardous liquid pipeline safety regulation. The table below shows the status of each state’s natural gas and hazardous liquid pipeline safety authority as of 2014.
Certification | ![]() |
Agreement | ![]() |
Interstate Agent | ![]() |
None | ![]() |
Definitions for each level of authority appear below the table.

Certification: Congress permitted States to assume regulatory authority of intrastate pipelines if the state makes an annual certification to the federal Office of Pipeline Safety. The State must adopt the minimum Federal regulations and may adopt more stringent regulations for intrastate pipelines as long as the state regulations are not incompatible with Federal regulations. Under Certification, a State has responsibility for enforcement of regulations on intrastate pipelines. All states other than Alaska and Hawaii give annual certifications to OPS to allow them to regulate intrastate natural gas pipelines but only about a dozen states certify for liquid pipelines. [Under Section 60105(a) Certification]
Agreement: If a state does not meet the requirements for certification, the State can still enter an agreement with OPS to oversee certain aspects of intrastate pipeline safety. In this case, OPS retains responsibility for enforcement for any violations on intrastate pipelines. This is an infrequently used approach. Only two states, Kentucky and Indiana, use an agreement to oversee liquid pipelines. [Under Section 60106(a) Agreement]
Interstate Agent: OPS may permit a State to participate in the oversight of interstate pipeline transportation, but OPS always retains authority for enforcement of any violations. Nine states have an interstate agent agreement to oversee natural gas pipelines and five have one for oversight of liquid pipelines.
* Virginia municipal intrastate gas systems do not operate under the state certification; they have a separate Agreement (under Section 60106(a)) with PHMSA).
