C&H Sugar to Pay $500,000, Add Fixes in Contra Costa Odor Case

Prosecutors say operational disruptions at a co-owned wastewater plant created excessive sewage odors during a 2022 heat wave.

Overview

  • The Contra Costa County district attorney announced a civil settlement requiring C&H Sugar to pay $400,000 in penalties and $100,000 in costs over 2022 emissions violations in Crockett.
  • Under the judgment, C&H must install a backup generator, replace diffuser heads in all three reactors, upgrade blower motors, complete a comprehensive internal audit, and operate a 24-hour toll-free community hotline.
  • Prosecutors said the odors stemmed from operational disruptions between Sept. 8 and Oct. 14, 2022, and unusually high temperatures worsened the impact on nearby residents.
  • The Bay Area Air Quality Management District investigated the incidents and referred the matter to the district attorney for enforcement.
  • District Attorney Diana Becton said the company cooperated and that the compliance framework aims to prevent future public nuisances, following widespread complaints and protests in 2022.
