Information Sheet IS-34 <br /> Reissued Waste Discharge Requirements General Order R5-2013-0122 <br /> Existing Milk Cow Dairies <br /> groundwater. This process includes ongoing monitoring and analysis, field studies of <br /> management alternatives, and more intensive evaluation of existing practices, including existing <br /> manure storage ponds and nutrient management plans. <br /> Considering the need to evaluate the effectiveness of current practices that are being <br /> implemented to comply with the Dairy Order, the Regional Board finds that it is not possible in <br /> all circumstances for dairy facilities to immediately comply with groundwater limitations. <br /> Accordingly, the Dairy Order provides dischargers with an appropriate amount of time to comply <br /> with such limitations. The time being provided is consistent with the time frames established in <br /> the MRP with respect implementation of RMPs. <br /> Individual Monitoring Orders:The Executive Officer has issued orders to each dairy that require <br /> the dairies to either submit individual groundwater monitoring and sampling plans or join a <br /> representative groundwater monitoring program. Submitted groundwater monitoring and <br /> sampling plans must include a schedule to install groundwater monitoring wells into first <br /> encountered groundwater, to collect representative groundwater samples from the wells and <br /> have these samples analyzed by a State-certified laboratory for selected constituents, and to <br /> report the results back to the Board. The first phase of orders were issued to those dairies <br /> where nitrate-nitrogen was detected at 10 milligrams per liter or more in any one domestic well, <br /> agricultural well, or subsurface (tile) drainage system in the vicinity of the dairy. The Executive <br /> Officer further prioritized the orders based on factors such as: proximity to a municipal or <br /> domestic supply well, artificial recharge area, or Department of Pesticide Regulation <br /> Groundwater Protection Area; nitrate concentrations in neighboring domestic wells; number of <br /> crops grown per year; whether or not the NMP was completed by 1 July 2009; and any other <br /> pertinent site-specific conditions. A summary of how the Executive Officer determined priorities <br /> for installation of monitoring wells is provided in Table 5 of Attachment A to the MRP. <br /> What Has Been Done Under the 2007 General Order? <br /> The 2007 General Order established a schedule for Dischargers to develop and implement their <br /> Waste Management Plan (WMP) and NMP and required them to make interim facility <br /> modifications as necessary to protect surface water and groundwater, improve storage capacity, <br /> and improve the facility's nitrogen balance before all infrastructure changes are completed. The <br /> 2007 General Order required that all Dischargers submit: <br /> • By 31 December 2007 <br /> o Existing Conditions Report (Attachment A). <br /> • By 1 July 2008 <br /> o Annual Report including Annual Dairy Facility Assessment (an update to the <br /> Preliminary Dairy Facility Assessment of Attachment A) with interim facility <br /> modifications considered to be implemented. <br /> o Statement of Completion of the following items in Attachment C (Nutrient <br /> Management Plan): <br />
