An Annual Report shall be submitted to the Regional Board by 1 February of each year. This report shall contain an evaluation of the effectiveness and progress of the investigation and remediation, and may be substituted for the second semi-annual monitoring report. The Annual Report shall contain the following minimum information: (a) both tabular and graphical summaries of all data obtained during the year; (b) groundwater contour maps and pollutant concentration maps containing all data obtained during the previous year; (c) a discussion of the long-term trends in the concentrations of the pollutants in the groundwater monitoring wells; ” (d) an analysis of whether the pollutant plume is being captured by an extraction system or is continuing to spread;
