Sunol sand-mining company Mission Valley Rock agrees to pay Water Resources Control Board fine
A company operating a sand-mining facility in Alameda County will pay hundreds of thousands of dollars to settle charges that it discharged untreated wastewater into Alameda Creek last year, officials with the state Water Resources Control Board (WRCB) said Thursday. Mission Valley Rock must pay nearly the statutory limit after it allegedly discharged 41,000 gallons of untreated wastewater from its Sunol facility in March. The total settlement is $368,940. According to the WRCB, Mission Valley Rock failed to properly decommission a pipeline, which then ruptured, depositing several inches of sediment in the creek bed and along the bank.
