On March 29, 2006, the Orange County Water Reclamation Division submitted a petition to initiate rulemaking to establish a Site Specific Alternative Criterion (SSAC) for pH of not greater than 8.5 standard units in the Orange County Eastern Water Reclamation Facility wetlands discharge system. The water body is classified as Class III waters with a designated use of “Recreation, Propagation and Maintenance of a Healthy, Well-Balanced Population of Fish and Wildlife.” The proposed site specific alternative criterion for pH is designed to protect this designated use.
