The U.S. EPA announced settlements with four Oakland companies—Sierra Pacific Ready Mix, Argent Materials, National Recycling Corp., and Nor-Cal Rock—over Clean Water Act violations. Under the terms of the settlements, the companies will pay a combined $137,000 in civil penalties and will better manage storm water runoff.

“San Francisco Bay, a National Estuary, provides crucial fish and wildlife habitat in an urban area of over seven million people,” said EPA Pacific Southwest Regional Administrator Mike Stoker. “It is essential that industrial facilities protect the bay, and those who depend on its ecological health, from polluted storm water.”

EPA partnered with the San Francisco Bay Regional Water Quality Control Board to inspect concrete, motor vehicle parts and recycling facilities in East and West Oakland. The inspections were part of an initiative by the California EPA statewide Environmental Justice Task Force, which focuses compliance and enforcement efforts related to air, water, toxics, solid waste, and pesticides.

EPA conducted a total of six inspections between February and March 2017, which resulted in enforcement actions against:

  • Sierra Pacific Ready Mix (also known as Allied Redy-Mix), a ready-mix concrete manufacturing facility – $72,169 penalty
  • Argent Materials, a concrete and asphalt recycling facility – $27,000 penalty
  • National Recycling Corporation, a recycling facility – $23,106 penalty
  • Nor-Cal Rock, a concrete and asphalt recycling company – $15,000 penalty

Each of the companies failed to develop and implement an adequate storm water pollution prevention plan and failed to use best management practices designed to prevent contaminants from entering storm water. Sierra Pacific Ready Mix and Nor-Cal Rock also discharged storm water containing industrial pollutants without first obtaining a permit.
