paraphase text Prescriptive designs for engineered alternatives provided by the 27 CCR 20080(b), must maintain containment capabilities in all components [4]. A standard liner option must perform all criteria mentioned to meet the prescriptive design standards to be a chemically compatible liner system (of equal or lesser equivalent hydraulic conductivity). When reviewing the 27 CCR 20080(b) and (c), all engineered alternatives must be specified in construction and reports [4]. Alternatives must be considered under the prescriptive standards stated in the SWRCB [5]. An alternative will be approved once a discharger demonstrates: Consistent with performance goals; equivalent protection against water quality impairment; and discharger compliance with prescriptive standards
