WASTE DISCHARGE REQUIREMENTS ORDER NO.R5-2003-0178 - 11- MORADA PRODUCE COMPANY LINDEN PACKING SHED SAN JOAQUIN COUNTY C. Effluent Limitations 1. The maximum total nitrogen loading to the land application areas shall not exceed the agronomic rate for plant available nitrogen (PAN) for the type of crop to be grown, as specified in the most recent edition of the Western Fertilizer Handbook. PAN shall be calculated as 100 percent of the total nitrogen content of the waste, unless and until the Discharger demonstrates that another proportion is technically justified, as described in Provision No. G.14. 2. The maximum BODS loading to the land application areas shall not exceed any of the following, unless the Discharger demonstrates that another loading rate is technically justified, as described in Provision No. G.13 : a. 300 lbs/acre on any single day; b. 100 lbs/acre-day as a 7-day average; c. The maximum loading rate that ensures that the discharge will not create a nuisance. 3. Wastewater discharged to the land application area shall not have a pH of less than 6.5 or greater than 8.4. 1). Land Application Area Specifications I. The discharge shall be distributed uniformly on adequate acreage in compliance with the Discharge Specifications. 2. Crops shall be grown on the application area. Crops shall be selected based on nutrient uptake capacity,tolerance to anticipated soil moisture conditions, and consumptive use of water and irrigation requirements. Cropping activities shall be sufficient to take up all the nitrogen applied. Crops shall be harvested and removed from the land application area. 3. Hydraulic loading of wastewater and irrigation water shall be at reasonable agronomic rates designed to minimize the percolation of process wastewater and irrigation water below the root zone (i.e., deep percolation). 4. The discharge of process wastewater, including runoff, spray or droplets from the irrigation system, shall not occur outside the boundaries of the land application area. 5. The Discharger may not discharge effluent to the land application area 24 hours before a predicted storm, during periods of precipitation, or within 24 hours after cessation of any precipitation event, nor shall effluent be discharged when the soil is saturated. 6. Wastewater conveyance lines shall be clearly marked as such. Wastewater controllers, valves, etc. shall be posted with advisory signs; all equipment shall be of a type, or secured in such a manner,that permits operation by authorized personnel only. 7. No physical connection shall exist between wastewater piping and any domestic water supply or other domestic/industrial supply well without an air gap or approved reduced pressure device.
