WASTE DISCHARGE REQUIREMENTS ORDER NO. -23- <br /> MUSCO FAMILY OLIVE COMPANY AND THE STUDLEY COMPANY <br /> WASTEWATER TREATMENT AND LAND DISPOSAL FACILITY <br /> SAN JOAQUIN COUNTY <br /> 2. The maximum total nitrogen loading to the LTUs shall not exceed 480 lbs/ac-year, or if the crop <br /> uptake is lower, the nitrogen loading shall not exceed the agronomic rate for the crop grown. <br /> Plant available nitrogen shall be calculated as 100-percent of the total nitrogen content of the <br /> waste, unless and until the Discharger demonstrates that another proportion is technically <br /> justified, as described in the Provisions. <br /> 3. The maximum BOD, loading to the LTUs shall not exceed any of the following: <br /> a. 300 lbs/acre on any single day; <br /> b. 100 lbs/acre•day as a 7-day average; <br /> c. The maximum loading rate that ensures that the discharge will not create a nuisance. <br /> 4. Wastewater discharged to the LTUs shall not have a pH of less than 6.5 or greater than 8.5. <br /> D. Land Application Areas Specifications <br /> 1. The discharge shall be distributed uniformly on adequate acreage in compliance with the <br /> Discharge Specifications. <br /> 2. Crops shall be grown on the application areas and landscaped areas. Crops shall be selected <br /> based on nutrient uptake capacity, tolerance to high soil moisture conditions, and consumptive <br /> use of water and irrigation requirements. Cropping activities shall be sufficient to take up all <br /> the nitrogen applied. Crops shall be harvested and removed from the land application areas <br /> and landscaped areas. <br /> 3. Planting and harvesting of crops shall be staggered so that there are always two to three crops <br /> at a time. As described in the RWD, the process will be started by seeding alfalfa into one- <br /> third to one-half the sprayfrelds during the fall of 2002, while the remaining fields shall be <br /> double cropped with winter barley. <br /> 4. As described in the RWD, to prevent erosion, double crops shall be planted into existing <br /> stubble from previous crops whenever possible. <br /> 5. The Discharger shall use soil moisture monitoring and soil sampling to determine soil fertility <br /> status and shall take the necessary steps to maintain fertility. <br /> 6. As sprinkler nozzles and heads wear out, they should be replaced with low output, low <br /> pressure devices that minimize raindrop impacts on the clay soils. It is anticipated that it will <br /> take 2-3 years to accomplish this task. <br /> 7. Irrigation with process wastewater shall not be performed within 24 hours of a forecasted <br /> storm, during a precipitation event, 24 hours after a precipitation event, or when the ground is <br /> saturated. <br /> [iW1NWWYIbtnpNDP.Pd.Jm <br />
