LA-based company reaches $29,000 settlement with Ventura County DA over wastewater spill
A Paramount-based industrial coating company has reached a $29,736 settlement with the Ventura County District Attorney's Office over a 150-gallon spill of petroleum-contaminated wastewater into a creek bed, prosecutors said Friday.
Advanced Industrial Services, Inc. was also ordered to comply with certain permanent conditions prohibiting unlawful disposal of petroleum products, according to the DA's office. In November 2022, an investigation was launched into the wastewater spill after an employee of the California Natural Resources Group found petroleum byproduct in a dry creek bed in Fillmore.
The creek bed was located at a leased facility for motor oil manufacturer Dryden, but prosecutors said investigators later learned the wastewater had come from a truck being operated by a temporary employee of AIS. Investigators with the Ventura County DA's Office and California Department of Fish and Wildlife made the connection after going through evidence including interviews with witnesses, photos, tire tread analysis and logbook records, according to prosecutors.
They determined that between 4 a.m. and 4:49 a.m. one morning, a driver had backed up a vacuum truck operated by AIS into Grimes Canyon Creek and discharged about 150 gallons of petroleum-contaminated wastewater into a ravine which led into the creek bed, according to prosecutors.
The driver, a temporary employee of AIS, left the area without reporting the spill as required by law, prosecutors said. AIS, which lists services such as industrial painting and fireproofing, did not immediately respond to an emailed request for comment.
The U.S. Department of Energy previously investigated the company based in the city of Paramount in Los Angeles County, announcing a $10,600 penalty in December 2022 in connection with the a severe blasting injury suffered by an AIS employee working at the Lawrence Berkeley National Laboratory.
The University of California, which runs the lab, did not allow any further blasting work at the site to be performed by AIS.
The company had reported the incident "promptly" and cooperated with the federal agency's investigation while also carrying out its own probe, Department of Energy officials said in a letter addressing the president and CEO of AIS.

Exclusive-UnitedHealth eyes $1 billion deal to exit Latin America as insurer refocuses on US, sources say
By Tatiana Bautzer and Sabrina Valle NEW YORK (Reuters) -UnitedHealth Group is weighing multiple bids for its Latin American operations, according to two people with direct knowledge of the matter, as the insurer buckles down after a series of unprecedented missteps that include the ouster of its CEO and a reported criminal accounting probe. The largest U.S. health insurer has been trying to exit Latin America since 2022, but the sale of Banmedica has taken on increasing urgency in recent months as the insurer took hits on multiple fronts, according to one of the people. New CEO Steve Hemsley told shareholders last week that he was determined to earn back their trust after an earnings miss and a Wall Street Journal report that the company was under criminal investigation for alleged Medicare fraud. UnitedHealth has said it was not notified by the Department of Justice and that it stands by the integrity of its operations. Hemsley replaced Andrew Witty as CEO, who had been in the post for only a matter of months following the murder of his predecessor, Brian Thompson, in New York in December while on his way to a meeting with investors. The company has four non-binding bids for its Banmedica subsidiary, which operates in Colombia and Chile, for about $1 billion, according to both people, who asked not to be identified because the talks are private. UnitedHealth's shares tumbled 25.5% in May alone and year-to-date are down 40%. UnitedHealth left Brazil in 2023 and Peru in March. It's aiming to get around $1 billion for Banmedica's operations in Colombia and Chile, the people said. The two people said the company expects to set a deadline for binding proposals as soon as July. UnitedHealth received bids from Washington, D.C.-based private equity firm Acon Investments; Sao Paulo-based private equity firm Patria Investments; Texas non-profit health firm Christus Health; and Lima-based healthcare and insurance provider Auna, the people said. Auna is in talks with a financial partner, one of the sources added. Banmedica's annual earnings before income taxes, depreciation and amortization, or EBITDA, is more than $200 million a year. Patria and Christus Health declined to comment. UnitedHealth, Acon and Auna did not respond to requests for comment. FAILED EXPANSION PLANS UnitedHealth bought Banmedica in 2018, with CEO David Scott saying he was "establishing a foundation for growth in South America for the next decades." At the time, UnitedHealth paid around 12 times Banmedica's EBITDA, according to one of the people. Three years later, the insurer decided to leave Latin America as it grappled with losses in its largest operation in the region, Brazil's Amil, which had been acquired a decade earlier. It divested from its Brazilian operations in late 2023. Banmedica is currently profitable, but is considered too small by UnitedHealth. It serves over 2.1 million consumers through its health insurance programs and has around 4 million patient visits annually across its network of 13 hospitals and 143 medical centers. UnitedHealth booked an $8.3 billion loss last year related to the sale of its South American operations - $7.1 billion stemming from the Brazil exit and $1.2 billion from Banmedica. "These losses relate to our strategic exit of South American markets and include significant losses related to foreign currency translation effects," the company said in a February filing. Brazilian investment bank BTG Pactual is advising UnitedHealth on the sale.
