The Northshore refinery has agreed to install new equipment to reduce flaring, after a neighborhood group documented 312 flaring events over 12 months using phone cameras and a shared spreadsheet.

“They told us it was rare. We showed them it wasn’t,” said organizer Jamal Pierce. The agreement with state regulators includes $2.1 million in penalties.

A refinery spokesperson said the company is committed to reducing emissions and meeting its obligations.
