This permit shall be effective from the date of issuance until March 31, 2007, shall void Permit No. WQ0000884 issued February 24, 1997, and shall be subject to the following specified conditions and limitations: 1. PERFORMANCE STANDARDS The Permittee shall submit a request to the Division by August 1, 2002 to modify the wastewater treatment system to include a Biological Nutrient Removal Upgrade to reduce effluent Plant Available Nitrogen (PAN). The upgrade to the system will be designed so that the wastewater treatment system will not exceed a cumulative loading of 350 lbs per acre per active growing season of Coastal Bermuda and a cumulative loading of 50 lbs per acre per active growing season of small grain overseed. Construction of the approved wastewater treatment system upgrade shall be complete within six months of permit issuance approving the proposed treatment upgrades. 2. The spray irrigation facilities shall be effectively maintained and operated at all times so that there is no discharge to the surface waters, nor any contamination of ground waters which will render them unsatisfactory for normal use. In the event that the facilities fail to perform satisfactorily, including the creation of nuisance conditions or failure of the irrigation area to adequately assimilate the wastewater, the Permittee shall take immediate corrective actions including those actions that may be required by the Division of Water Quality (Division), such as the construction of additional or replacement wastewater treatment and disposal facilities. 2. Adequate records shall be maintained by the Permittee tracking the amount of wastewater disposed. These records shall include, but are not necessarily limited to, the following information: a. date of irrigation, b. volume of wastewater irrigated, c. field irrigated, d. length of time field is irrigated, e, continuous weekly, monthly, and year-to-date hydraulic (inches/acre) loadings for each field, f. continuous weekly, monthly, and year-to-date PAN (pounds/acre) loadings for each field and crop, g. nitrogen balance for each field and crop after an application event, h. any ponding or runoff of wastewater from the irrigation fields, i. maintenance of cover crops, j. maintenance performed on the wastewater treatment and irrigation facilities, and k. wastewater and surface water sample collection activities. 3. Influent flow shall be continuously monitored and daily flow values shall be reported on Form NDMR. The Permittee shall install an appropriate flow measurement device consistent with approved engineering and scientific practices to ensure the accuracy and reliability of influent flow measurement. Flow measurement devices selected shall be capable of measuring flows with a maximum deviation of less than 10 percent from true flow, accurately calibrated at a minimum of once per year, and maintained to ensure that the accuracy of the measurements is consistent with the accepted capability of that type of device. Records of flow measurement device calibration shall be kept on file by the Permittee for a period of at least three years. At a minimum, data to be included in this documentation shall be: a. Date of flow measurement device calibration b. Name of person performing calibration c. Percent from true flow Plans and specifications for the flow measuring device shall be prepared by a licensed Professional Engineer and submitted to the appropriate regional office 30 days prior to installation. The flow measuring device shall be installed within 1 year of the date of this perm it. 4. The effluent from the subject facilities shall be monitored by the Permittee at the point prior to irrigation twice per month for the following parameters: BODS TSS Fecal Coliform pH NH3 as N Total Kjeldahl Nitrogen NO3 as N Oil and Grease Total Organic Carbon Sodium Magnesium Calcium Sodium Adsorption Ratio by Calculation 5. Samples shall be collected monthly from the surface waters at the five locations marked by an "X" on Figure 1 and analyzed by a certified laboratory for the following parameters: Total Organic Carbon Total Kjeldahl Nitrogen Nitrates Fecal Coliform NH3 pH 6. The Permittee shall maintain records of all cutting and harvesting events on the irrigation fields. These shall include the date of cutting or harvesting, how many acres are harvested, and the amount of hay harvested. 4
