Information Sheet IS-28 Reissued Waste Discharge Requirements General Order R5-2013-0122 Existing Milk Cow Dairies properly graded and drained; all portions of the production area shall be designed and maintained to convey all water that has contacted animal wastes or feed to the wastewater retention system and shall be designed and maintained to minimize standing water. Standing water is not to be present as of 72 hours after the last rainfall. Dischargers shall implement any newly identified management practices/activities from the Summary Representative Monitoring Report which are applicable for their facility on a time schedule that is as short as practicable but cannot exceed 10 years. Land Application Area Specifications: This General Order includes land application specifications that require Dischargers to develop and implement a Nutrient Management Plan (NMP) that provides protection of both surface water and groundwater. The contents of the NMP and technical standards for nutrient management are specified in Attachment C to this General Order. The land application specifications also require Dischargers to have a written agreement with each third party that receives process wastewater from the Discharger for its own use. The written agreement will be effective until the third party is covered under waste discharge requirements or a waiver of waste discharge requirements that are adopted by the Central Valley Water Board and that are specific to the application of the Discharger's process wastewater to land under the third party's control. The written agreement must identify the Discharger, the third party, the Assessor's Parcel Number and acreage of the cropland where the process wastewater will be applied, and the types of crops to be fertilized with the process wastewater. The written agreement must also include an agreement by the third party to: (1) use the process wastewater at agronomic rates appropriate for the crop(s) grown, and (2) prevent the runoff to surface waters of wastewater, storm water or irrigation supply water that has come into contact with manure or is blended with wastewater. The technical standards for nutrient management require Dischargers to monitor soil, manure, process wastewater, irrigation water, and plant tissue. The results of this monitoring are to be used in the development and implementation of the NMP. The Dairy General Order also requires Dischargers to create and maintain specific records to document implementation and management of the minimum elements of the NMP, records for the land application area, a copy of the Discharger's NMP, and records on manure, bedding, and process wastewater transferred to other persons. If existing management practices implemented in the land application area(s) are found not to be sufficiently protective of underlying groundwater, a dairy must change its management practices in accordance with the time schedule for compliance detailed in section M. of the reissued Dairy General Order. Alternatively, if groundwater monitoring demonstrates that a discharge of waste threatens to exceed a water quality objective, the Executive Officer may issue an order to the owner/operator of the monitored dairy to identify and implement management practices that are protective of groundwater quality on a schedule that is as short as practicable (Reissued Dairy General Order, General Specification B.5) Closure Provisions:This General Order includes a provision that the Discharger must maintain coverage under this Order or a subsequent revision to this Order until all manure, process
