FORWARD CLASS II LANDFILL SAN JOAQUIN COUNTY m) Results of the corrective action monitoring. n) A description of the measures undertaken to implement the "Forward Landfill Odor Control Management Plan" (revised September 2007) and the "Odor Impact Minimization Plan" (dated March 2009). 2) Annual Monitoring Report: The Discharger shall submit an Annual Monitoring Report to the Central Valley Water Board by 1 February covering the reporting period of the previous monitoring year. If desired, the Annual Monitoring Report may be combined with the fourth quarter report, but if so, shall clearly state that it is both a quarterly and annual monitoring report in its title. Each Annual Monitoring Report shall contain the following information: a) All monitoring parameters, if detected, shall be graphed to show historical trends at each monitoring point and background monitoring point, for all samples taken within at least the previous five calendar years. If a 5-year COC event was performed, the detected parameters shall be graphically presented if they were also detected during any previous COC event. Each such graph shall plot the concentration of one or more constituents for the period of record for a given monitoring point or background monitoring point, at a scale appropriate to show trends or variations in water quality. The graphs shall plot each datum, rather than plotting mean values. Graphical analysis of monitoring data may be used to provide significant evidence of a release. b) An evaluation of the monitoring parameters with regards to the cation/anion balance, and a graphical presentation using a Stiff diagram, a Piper graph, or a Schoeller plot. c) All historical monitoring data for which there are detectable results, including data for the previous year, shall be submitted in tabular form in a digital file format such as a computer disk. The Central Valley Water Board regards the submittal of data in hard copy and in digital format as "...the form necessary for..." statistical analysis [Title 27, section 20420(h)], that facilitates periodic review by the Central Valley Water Board. d) Hydrographs of each well showing the elevation of groundwater with respect to the elevations of the top and bottom of the screened interval and the elevation of the pump intake. Hydrographs of each well shall be prepared quarterly and submitted annually. e) A comprehensive discussion of the compliance record, and the result of any corrective actions taken or planned which may be needed to bring the Discharger into full compliance with the waste discharge requirements. f) A map showing the area and elevations in which filling has been completed during the previous calendar year and a comparison to final closure design
