Cleanup activities will include dredging and disposing of sediments, and continuing a public advisory to publicize risks from eating contaminated seafood. Sediments are contaminated primarily with polychlorinated biphenyls (PCBs), metals, dioxins/furans, tributyltin (TBT), and carcinogenic polycyclic aromatic hydrocarbons (cPAHs).
Two Los Angeles-based consulting firms, MotorScience and MotorScience Enterprise, and their owner, Chi Zheng, have agreed to have a stipulated judgment entered against them for a $3.55 million civil penalty and to pay an additional $60,000 civil penalty within six months, to settle alleged Clean Air Act (CAA) violations stemming from the illegal import of 24,478 all-terrain, recreational vehicles into the U.S. from China without emissions testing, the EPA, California Air Resources Board and Department of Justice announced. MotorScience obtained EPA certificates of conformity for numerous vehicles without required testing, reusing results from a handful of vehicles, the agency says.
