Attachment C C-6 <br /> Reissued Waste Discharge Requirements General Order R5-2013-0122 <br /> Existing Milk Cow Dairies <br /> Technical Standards for Nutrient Management <br /> The Discharger shall comply with the following Technical Standards for Nutrient <br /> Management in the development and implementation of the Nutrient <br /> Management Plan (NMP). <br /> I. Sampling and Analysis <br /> Soil, manure, process wastewater, irrigation water, and plant tissue <br /> shall be monitored, sampled, and analyzed as required in Monitoring <br /> and Reporting Program R5-2013-0122, and any future revisions <br /> thereto. The results of these analyses shall be used during the <br /> development and implementation of the NMP. <br /> II. Crop Requirements <br /> A. Realistic yield goals for each crop in each land application area shall <br /> be established. For new crops or varieties, industry yield <br /> recommendations may be used until documented yield information is <br /> available. <br /> B. Each crop's nutrient requirements for nitrogen, phosphorus, and <br /> potassium shall be determined based on recommendations from the <br /> University of California, Western Fertilizer Handbook (9th Edition), or <br /> from historic crop nutrient removal. <br /> III. Available Nutrients <br /> A. All sources of nutrients (nitrogen, phosphorus, and potassium) <br /> available for each crop in each land application area shall be identified <br /> prior to land applications. Potential nutrient sources include, but are <br /> not limited to, manure, process wastewater, irrigation water, <br /> commercial fertilizers, soil, and previous crops. <br /> B. Nutrient values of soil, manure, process wastewater, and irrigation <br /> water shall be determined based on laboratory analysis. "Book values" <br /> for manure and process wastewater may be used for planning of waste <br /> applications during the first two years during initial development of the <br /> NMP if necessary. Acceptable book values are those values <br /> recognized by American Society of Agricultural and Biological <br /> Engineers (ASABE), the Natural Resources Conservation Service <br /> (NRCS), and/or the University of California that accurately estimate the <br /> nutrient content of the material. The nutrient content of commercial <br />
