002.02A Set Backs and Buffer Zones
002.02B Soil and Crop Criteria
002.02A1 There shall be no public drinking water wells within 500 feet of the application area.
002.02A2 There shall be no private drinking water wells within 100 feet of the application area.
002.02A3 Effluent shall not be applied to sites less than 100 feet from any inhabited dwellings.
002.02A4 Land application sites shall not be located within or adjacent to residential areas.
002.02A5 Effluent shall not be allowed to exceed the land application site boundaries.
002.02A6 Effluent application, runoff or spray shall not be allowed on public roadways.
002.02C Land Application Site Prohibitions
002.02B1 Treated effluent shall be land applied at an agronomic rate. Agronomic rate is defined as the application rate of nitrogen to meet the estimated nitrogen requirements of the crop being produced based on past or projected yields. In determining the agronomic rate, the permittee shall consider the nitrogen content of the wastewater, available nitrogen in the soil, and the amount of nitrogen from commercial fertilizer. Any laboratory testing or other documentation regarding the determination of agronomic rate for the land application site shall be retained by the permittee. Documentation shall be made available immediately upon request to NDEQ.
002.02B2 Treated wastewater shall not be applied to crops that are intended for distribution in their raw form for direct human consumption (e.g. fresh produce).
002.02D Ground Water Criteria
002.02C1 Land application shall not be conducted when the ground is frozen or saturated.
002.02C2 Land application sites shall have a slope of 12% or less.
002.02C3 Surface runoff of effluent shall be prohibited. Application of wastewater shall cease immediately if ponding or runoff occurs.
002.02C4 Land application sites shall be free of perennial or intermittent streams, ponds, lakes or wetlands.
002.02E Effluent Criteria
002.02D1 There shall be no impairment to the beneficial uses of ground water. Any substance introduced directly or indirectly by human activity shall not be allowed to exceed the applicable standards for ground water as set forth in Chapter 4, of Title 118 - Ground Water Quality Standards and Use Classification
002.02D2 The distance of land surface to the seasonal high groundwater level as specified either by a soil survey map or well logs, shall be, at a minimum, greater than 4 feet.
002.02D3 Where the potential for ground water contamination is a concern, the NDEQ may require monitoring wells to be installed and ground water monitoring to be conducted.
002.02F The permittee shall maintain and retain logs containing the following information;
002.02E1 The total hydraulic application rate shall be based on weekly local crop uptake values. (This information may be obtained through the County Extension Office or the Natural Resource District.) The total hydraulic application rate shall not exceed 2 inches per acre (54,304 gallons) per week.
002.02E2 Treated wastewater used for land application must comply with all numeric and narrative limits, conditions and requirements set forth herein.
002.02E3 The effluent shall be monitored for the following parameters; pH, Total Kjeldahl Nitrogen, Nitrate as Nitrogen, Ammonia as Nitrogen, Total Dissolved Solids, Chloride, Phosphorous and Sodium Adsorption Ratio (SAR).
002.02G Monitoring Frequency Requirements
002.02F1 Each land application site shall be identified in the log by the legal description. All information pertaining to that land application site shall be identified as such.
002.02F2 The inches per acre per week of treated wastewater applied to each land application site. The beginning and ending date of the week shall be noted in the log.
002.02F3 The results of the laboratory analysis for the following parameters; pH, Total Kjeldahl Nitrogen, Nitrate as Nitrogen, Ammonia as Nitrogen, Total Dissolved Solids, Chloride, Phosphorous, and Sodium Adsorption Ratio (SAR). A copy of the laboratory analysis shall be attached to the log entry.
002.02F4 Any additional nitrogen applied to the land application site per irrigation season per year. The amount of nitrogen shall be reported in tons per acre per year.
002.02F5 If additional nitrogen is applied to the application site, the source and amount from each source shall be noted in the log.
002.02F6 The permittee shall make these logs available for review upon request by NDEQ.
002.02G1 The monitoring frequency for Restricted Public Access Sites shall be, at a minimum, annually. The effluent shall be sampled on the first day of land application.
002.02G2 The monitoring frequency for Unrestricted Public Access Sites shall be, at a minimum, once during the first week of the initial land application (irrigation) event and once every month thereafter for all parameters except flow.
