Docket Search​

Dockets are how the PSC organizes correspondence with utilities, contractors, and other relevant parties. This information is available to the public using the Electronic Records Filing System. They are formatted in three parts (utility ID, case type code, sequence number) separated by hyphens (e.g. 5-TI-100).

  • utility ID can be found by using the Universal Name File Search
  • case type code can be found in the Case Type Lookup or listed below for the gas-specific sections
  • sequence number increments by one for subsequent filings (for the same utility and type) or is the relevant year for the docket

These dockets contain enforcement of federal and state code for each calendar year. They contain inspections that were performed that year including any potential code violations, correspondence, and follow up.

A listing of both types of dockets can be found in this spreadsheet: Pipeline Safety Dockets
