Lead investigators will present their findings on the explosion to the five-member board on Aug. 30, NTSB spokesman Peter Knudson said.
The presentation will cover topics including what caused the pipeline to rupture, the emergency response, and the human toll of the tragedy, which killed eight people and destroyed 38 homes.
Board members will ask questions and discuss the findings, Knudson said.
Revisions will then be made to the draft before the NTSB issues a final version of the report, a process that typically takes a couple of weeks, Knudson said.
San Bruno Mayor Jim Ruane, City Manager Connie Jackson and other city officials will be traveling to the Capitol to attend the meeting, Jackson said.
"We think it's incredibly important that we're there to hear and understand the board members' discussion and their final action on the report," Jackson said.
No advance information about the content of the report will be released before it is presented to the board, Jackson said.
"We don't know what the results will be," she said. "We'll hear them at the same time everybody else does at the board meeting."
