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.

Solar tracking and manufacturing company PV Hardware USA is increasing its production capacity and expanding its Houston facility in an effort to meet growing demands.

The move marks the company's third expansion in the Houston area in three years. PV Hardware reports a 400 percent surge in national market growth over the past three years, as solar-based projects have been pivotal in energy resilience efforts.

PV Hardware plans to increase the capacity at its Houston facility by 42 percent, according to a news release. With the additional capacity, PV Hardware expects a 35 percent increase in production of pre-assembled parts. The company has not announced whether any additional employees will be hired or the costs of expansion.

In September, the company completed its new dedicated pre-assembly facility, which will help migrate difficult assembly into an easier manufacturing setting. The new pre-assembly area will also assist with streamlined field installation, enhanced schedule predictability and reduction of manual labor.

Citybiz reports that the expansion totals approximately 34,200 square feet.

PV Hardware USA aims to make solar installation more efficient. For large-scale solar projects, PV Hardware USA’s pre-assembly process helps to relieve assembly work done by installation teams. According to PV Hardware USA, it reduces the number of on-site components by 70 percent.

“Traditionally, manufacturers pushed the assembly burden onto the jobsite,” Rodolfo Bitar, vice president of business development for PVH USA, told Renewable Energy Magazine. “We ask a different question: what work can be done more efficiently before the equipment ever leaves the factory? By managing the assembly of 188 loose parts per row in our controlled manufacturing environment, we remove field complexity and make installation highly predictable.”

PV Hardware USA produces single-axis solar trackers made in Texas and has supplied over 52 gigawatts of solar trackers worldwide.

“The expanded presence in Texas underscores a long-term commitment: bringing world-class solar expertise to local American manufacturing, supporting communities, and serving as a reliable partner through the clean energy transition,” the company said in the release.

In July of 2025, the company opened its 95,000-square-foot facility, which was the second Houston location following its initial $30 million U.S. manufacturing facility, which, at 50,000 square feet, is one of America's largest solar tracker manufacturing facilities.
