In December 2013, the NRDC won a lawsuit against the California Department of Public Health, and the state was required to issue a standard on the maximum contaminant level (MCL) for chromium by “no later than June 15, 2014.”[45] The MCL was added to the California Code of Regulations but, in 2017, another court ruled that the standard must be eliminated because the California Department of Public Health had not proven that the standard was economically feasible.[46]
