Oil company Phillips 66 has been federally indicted in connection with alleged violations of the Clean Water Act in California, authorities said Thursday.

The Houston-based company is accused of discharging hundreds of thousands of gallons of industrial wastewater containing excessive amounts of oil and grease, the U.S. Department of Justice said.

The company allegedly dumped the wastewater from its Carson oil refinery into the Los Angeles County sewer system in 2020 and 2021 and did not report the violations, prosecutors said.

Phillips is charged with two counts of negligently violating the Clean Water Act and four counts of knowingly violating the Clean Water Act. The company faces up to five years of probation on each count and a maximum of $2.4 million in fines.

An arraignment date has not been set.

“Phillips 66 will continue its cooperation with the U.S. Attorney’s office and is prepared to present its case in these matters in court,” a spokesperson said in a statement Thursday. “The company remains committed to operating safely and protecting the health and safety of our employees and the communities where we operate.”

Last month, Phillips announced it would close its Southern California refinery by the end of 2025, citing market concerns. That refinery accounts for about 8% of California’s refining capacity, according to the state’s Energy Commission.

The company also operates a refinery near San Francisco that accounts for about 5% of California’s refining capacity, according to the state Energy Commission.

Houston-based ExxonMobil and Rice University announced a master research agreement this week to collaborate on research initiatives on sustainable energy efforts and solutions. The agreement includes one project that’s underway and more that are expected to launch this year.

“Our commitment to science and engineering, combined with Rice’s exceptional resources for research and innovation, will drive solutions to help meet growing energy demand,” Mike Zamora, president of ExxonMobil Technology and Engineering Co., said in a news release. “We’re thrilled to work together with Rice.”

Rice and Exxon will aim to develop “systematic and comprehensive solutions” to support the global energy transition, according to Rice. The university will pull from the university’s prowess in materials science, polymers and catalysts, high-performance computing and applied mathematics.

“Our agreement with ExxonMobil highlights Rice’s ability to bring together diverse expertise to create lasting solutions,” Ramamoorthy Ramesh, executive vice president for research at Rice, said in the release. “This collaboration allows us to tackle key challenges in energy, water and resource sustainability by harnessing the power of an interdisciplinary systems approach.”

The first research project under the agreement focuses on developing advanced technologies to treat desalinated produced water from oil and gas operations for potential reuse. It's being led by Qilin Li, professor of civil and environmental engineering at Rice and co-director of the Nanosystems Engineering Research Center for Nanotechnology-Enabled Water Treatment (NEWT) Center.

Li’s research employs electrochemical advanced oxidation processes to remove harmful organic compounds and ammonia-nitrogen, aiming to make the water safe for applications such as agriculture, wildlife and industrial processes. Additionally, the project explores recovering ammonia and producing hydrogen, contributing to sustainable resource management.

Additional projects under the agreement with Exxon are set to launch in the coming months and years, according to Rice.
