<br />Subsection (c) pertains to more continuous and intensive land application activities <br />based on a combination of crop uptake and land treatment techniques. <br /> <br />(a) Operators may avoid the cost and effort associated with a site-specific <br />agronomic analysis as described in subsection (b) below if no supplemental or <br />commercial fertilizers are utilized in addition to the manure and process <br />wastewater generated by the facility, and if the proper land application rate is <br />based on the applicable data presented in Appendices 0 and E. Crop nitrogen <br />uptake rates shall be computed as shown in Appendix 0 based on the <br />specified crop yields, In addition, the operator shall rely on the tabie values for <br />total nitrogen content in manure and process wastewater as shown in <br />Appendix E in computing the proper application rate. The operator shall limit <br />application based on the assumption that all of the total nitrogen applied from <br />manure and process wastewater is plant available during the year following the <br />manure application. <br /> <br />(b) Operators may apply manure and process wastewater on a year to year basis <br />at rates greater than allowed in subsection (a) above based on a site-specific <br />agronomic analysis that includes, all plant available nutrient inputs from <br />manure/process wastewater, irrigation water, legumes, residual soil nutrients, <br />and soil organic matter, based upon site specific soil, water and <br />manure/process wastewater analyses. These data, plus the yield goal for the <br />crop to be grown, will be used to calculate appropriate manure/process <br />wastewater and supplemental fertilizer nutrient additions. Management factors <br />such as manure handling, application method, tillage, irrigation regime, <br />cropping and grazing patterns and site factors such as soil texture, slope. and <br />aspect will be used to modify the manure/process wastewater application <br />rates. The operator shall maintain copies of the agronomic analyses which are <br />being relied upon for the purpose of limiting land application rates of manure <br />and process wastewater. Copies of such analyses shali-be available for <br />inspection at the facility and records shall be maintained for a minimum of <br />three years. <br /> <br />(c) Operations which land apply manure or process wastewater in an amount <br />exceeding the agronomic rates determined under subsection (5)(b) or on a <br />continuous or near continuous basis must comply with this subsection (5) (c). <br /> <br />(i) No later than 180 days following August 30, 1992 for existing facilities <br />and prior to land application for new facilities or facilities planning to <br />calculate their land application rate pursuant to this subsection (c), the <br />operator shall submit for the Division's approval, a land application plan <br />designed to demonstrate that said rate will not result in exceedances of <br />applicable water quality standards or numerical protection levels <br />established pursuant to subsection 81.5(A)(5)(c)(iv), The required land <br />application plan must include, at a minimum: <br /> <br />10 <br />
