Frequency of monitoring during the day <br /> shall be sufficient to determine if runoff is occurring. <br /> f <br /> In addition,the Discharger shall maintain a log of discharges to the land application area. Observations <br /> shall be noted and shall record which check is receiving wastewater, observations of ponding water, soil <br /> clogging, odors, insects, or other potential nuisance conditions. The notations shall also document any <br /> corrective actions taken. A copy of the notations recorded each month shall be submitted along with <br /> 4 monthly monitoring reports. <br /> GROUNDWATER MONITORING <br /> The following monitoring requirement is only necessary if the Discharger installs groundwater <br /> monitoring wells as a result of the Effluent Evaluation. If wells are installed, then this program shall be <br /> effective beginning with the second quarter of 2004. If the Discharger elects to install lysimeters instead <br /> of groundwater monitoring wells, then this same program is in effect, with the exception of the first four <br /> items in the table below. If lysimeters are installed,then this program is also effective beginning with <br /> the second quarter of 2004. <br /> Prior to construction and/or sampling of any groundwater monitoring wells, the Discharger shall submit <br /> i plans and specifications to the Regional Board for review and approval. Once installed, all new wells <br /> shall be added to the MRP and shall be sampled and analyzed according to the schedule below. <br /> Prior to sampling,the groundwater elevations shall be measured and the wells shall be purged at least <br /> three well volumes until temperature,pH and electrical conductivity have stabilized. Depth to <br /> groundwater shall be measured to the nearest 0.01 feet. Samples shall be collected using standard EPA <br /> methods. Groundwater monitoring shall include, at a minimum, the following; <br /> I <br />
