(c) The final use of the treated waste.
(3) Permittees shall maintain the records required by Part III B 10 b (1) and (2) on site for a period of three years. All records shall be made available to department personnel upon request.
11. Animal waste generated by this facility shall not be applied to fields owned by or under the operational control of either the permittee or a legal entity in which the permittee has an ownership interest unless the fields are included in the facility's approved nutrient management plan.
12. The permittee shall implement a nutrient management plan (NMP) developed by a certified nutrient management planner in accordance with § 10.1-104.2 of the Code of Virginia and approved by the Department of Conservation and Recreation and maintain the plan on site. The NMP shall address the form, source, amount, timing, and method of application of nutrients on each field to achieve realistic production goals, while minimizing nitrogen and phosphorus loss to ground and surface waters. The terms of the NMP shall be enforceable through this permit. The NMP shall contain at a minimum the following information:
a. Site map indicating the location of the waste storage facilities and the fields where waste will be applied;
b. Site evaluation and assessment of soil types and potential productivities;
c. Nutrient management sampling including soil and waste monitoring;
d. Storage and land area requirements;
e. Calculation of waste application rates; and
f. Waste application schedules.
13. Waste shall not be land applied within buffer zones. Buffer zones at waste application sites shall, at a minimum, be maintained as follows:
a. Distance from occupied dwellings not on the permittee's property: 200 feet (unless the occupant of the dwelling signs a waiver of the buffer zone);
b. Distance from water supply wells or springs: 100 feet;
c. Distance from surface water courses: 100 feet (without a permanent vegetated buffer) or 35 feet (if a permanent vegetated buffer exists). Other site-specific conservation practices may be approved by the department that will provide pollutant reductions equivalent or better than the reductions that would be achieved by the 100-foot buffer or 35-foot wide vegetated buffer;
d. Distance from rock outcropping (except limestone): 25 feet;
e. Distance from limestone outcroppings: 50 feet; and
f. Waste shall not be applied in such a matter that it would discharge to sinkholes that may exist in the area.
14. The following land application records shall be maintained:
a. The identification of the land application field sites where the waste is utilized or stored;
b. The application rate;
c. The application dates; and
d. What crops have been planted.
