Information Sheet IS-33 Reissued Waste Discharge Requirements General Order R5-2013-0122 Existing Milk Cow Dairies the Representative Monitoring Program. The submittal must include a description of the methods used in evaluating the groundwater monitoring data. No later than six (6) years following submittal of the first ARMR, the Representative Monitoring Program must produce a Summary Representative Monitoring Report (SRMR) identifying management practices for the various management units (i.e., production areas, land application areas and wastewater ponds) that are protective of groundwater quality for the range of conditions found at facilities covered by the Representative Monitoring Program. The identification of management practices for the range of conditions must be of sufficient specificity to allow participants covered by the Representative Monitoring Program and the Central Valley Water Board to identify which practices at monitored facilities are appropriate for facilities with a corresponding range of site conditions, and generally where such facilities may be located within the Central Valley (e.g., the summary report may need to include maps of the Central Valley that identify the types of management practices that should be implemented in certain areas based on specified site conditions). The summary report must include adequate technical justification for the conclusions incorporating available data and reasonable interpretations of geologic and engineering principles to identify management practices protective of groundwater quality. Further, the SRMR must include a proposed schedule for implementation of management practices that are protective of groundwater quality that is as short as practicable. Each ARMR must include an evaluation of whether the representative monitoring program is on track to provide the data needed to complete the SRMR. If the evaluation concludes that information needed to complete the summary report may not be available by the required deadline, the ARMR shall include measures that will be taken to bring the program back on track. The ARMR shall include an evaluation of data collected to date and an assessment of whether monitored dairies are implementing management practices that are protective of groundwater quality. If the management practices being implemented at a dairy being monitored are found to not be protective of groundwater quality, the Executive Officer can issue an order to the owner/operator of the monitored dairy to identify and implement management practices that are protective of groundwater quality prior to submittal of the report. Both the individual groundwater monitoring provisions and the RMP monitoring requirements are designed to measure water quality data in first-encountered groundwater. A RMP is further required to conduct such monitoring on a variety of dairy farms that represent the overall range of conditions on dairies within the Central Valley. This means for a RMP that a variety of physical site conditions must be monitored, such as varying soil types and depth to groundwater. Varying management practices must also be measured, such as different types of crops, irrigation methods, waste storage structures, and animal housing. In cases where water quality is not being sufficiently protected, additional time is needed to identify additional practices for the various dairy facility areas that both improve water quality protection, and are feasible and practicable for dairy operators to implement. This is a chief goal of the RMP process and work is actively underway, to be completed no later than 2019, to identify and verify additional practices where necessary to protect beneficial uses of
