PHMSA is proposing changes to the HL Accident Report form, some of which will mirror changes already accepted for the NG Gathering & Transmission Incident Report. Listed below are some important proposed changes. The comment period is open until May 8th, 2020. To view the proposed changes or make a comment, please see docket PHMSA-2019-0141-0003 or click on this link.
The proposal includes:
- Adding new items to build a complete timeline including interactions with emergency responders, spill response resources, and details about ignition. In addition, PHMSA is proposing new questions regarding detection, discovery, and confirmation of the accident.
- Collecting information on the operational status of the pipeline at the time of the accident.
- Requesting not just the first, but all subsequent, NRC notification numbers.
- Adding questions about initial actions the operator took to control the flow of products to the failure location.
- Adding a question to collect the date of the most recent evaluation of the water crossing. These formal evaluations can provide information critical to protecting the integrity of water crossings.
- Collecting the date of installation and manufacture for all items involved in the accident.
- Collecting more data on accident consequences including # of businesses affected, persons harmed but not hospitalized, and amount of HL product consumed by fire.
- Data on Maximum Pressure, its determination method, and Flow Reversals
- Updated questions and answers for Stray Current Corrosion and Natural Force Damage.
- Questions about the length of pipe isolated during/after an accident.
- Providing State Damage Prevention Law Exemptions by the Operator
- Adding “post-construction pressure test” questions for the Cause, “Material Failure of Pipe or Weld”.
- New, updated sections on Inspection Methods and Contributing Factors to the accident. ILI inspection questions will ask for more details on the type of tool, what it was tuned to detect, and the date of the previous and last inspections with each method. Direct Assessment inspection methods have also been updated. Contributing factors will be available to choose and should be explained in the Narrative section of the form.
