Exhibit a pH of less than 6.5 or greater than 8.5 pH units. <br /> C. Impart taste, odor, or color that creates nuisance or impairs any beneficial use. <br /> G. Provisions <br /> 1. All of the following reports shall be submitted pursuant to Section 13267 of the California <br /> Water Code and shall be prepared as described by Provision G.3. <br /> a. By 30 June 2006, the Discharger shall submit a Background Groundwater Quality Study <br /> Report. For each groundwater monitoring parameter/constituent identified in the MRP, the <br /> report shall present a summary of monitoring data, calculation of the concentration in <br /> background monitoring wells, and comparison of background groundwater quality to that in <br /> wells used to monitor the facility. Determination of background quality shall be made <br /> using the methods described in Title 27, Section 20415(e)(10), and shall be based on data <br /> from at least four consecutive quarterly(or more frequent) groundwater monitoring events. <br /> For each monitoring parameter/constituent, the report shall compare measured <br /> concentrations for compliance monitoring wells with: 1) the calculated background <br /> concentration, and 2) the interim numeric limitations set forth in Groundwater Limitation <br /> F.La. Where background concentrations are statistically greater than the interim limitations <br />
