In coordination with Department of Health Services' (DHS) efforts to gain 'State Authorization' to administer the federal hazardous waste management system regulations ('RCRA' regulations) in the State of California (State), the State Water Resources Control Board (State Board) and DHS have been involved since early 1988 in a joint effort to make their respective water quality monitoring regulations fully equivalent to their federal counterparts. Maintaining parallel water quality monitoring regulations between the two State agencies will simplify both administration of and compliance with the regulations. The State Board's new regulations totally replaced Article 5 (Water Quality Monitoring) of Chapter 15 and revised Section 2601 (Technical Definitions) of Article 10 of that chapter. Like their federal counterparts, the revised DHS regulations apply only to hazardous waste; however, revised Article 5 applies to classified waste management units (units) designed for classified waste (hazardous waste, designated waste, or nonhazardous solid waste). The principal new features of revised Article 5 include: (1) USEPA-equivalent statistical methods, plus allowances for retests in order to minimize false-positive indications; (2) two non-statistical methods for indicating the presence of a release; and (3) allowance of cleanup concentrations greater than background under certain instances.
