MONITORING AND REPORTING PROGRAM -2 - <br /> PAT <br /> 2 - <br /> PAT MITCHELL AND CALIFORNIA NATURAL PRODUCTS <br /> WASTEWATER TREATMENT AND DISPOSAL FACILITY <br /> SAN JOAQUIN COUNTY <br /> Total Nitrogen Loading Rate lbs/acre/month Calculated, Monthly <br /> BODS loading shall be calculated using the daily applied volume of wastewater, estimated <br /> daily application area, and applicable results of effluent BODS. Non-working time shall not <br /> be included in loading concentrations. <br /> , Total nitrogen loading rates shall be calculated using the daily applied volume of wastewater, <br /> estimated daily application area, and the most recent results of total nitrogen. <br /> . LAND APPLICATION AREA SOILS MONITORING <br /> The Discharger shall establish, with concurrence of Board staff, four soil profile monitoring locations and <br /> one representative background location (i.e., in an area that historically has not received process <br /> wastewater). The samples shall be collected and analyzed for at least the following constituents <br /> immediately upon implementation of this MRP, and at the following frequency thereafter: <br /> Constituents Units Soil Profile Frequency <br /> Soil pH pH Standard' Annually, <br /> Volatile Solids % Total Weight Standard' Annually, <br /> Cation Exchange Capacity meq/100 g Standard' Annually, <br /> Nitrate (as N) mg/kg Standard' Annually, <br /> Kjeldahl-Nitrogen(as N) mg/kg Standard' Annually, <br /> 1 Samples shall be collected at 0.5 feet, 3 feet, and 6 feet. <br /> , Samples shall be collected in September. <br /> In addition, the Discharger shall maintain a log of discharges to the land application area. Notations shall <br /> be made in a bound log book record which check is receiving wastewater, and observations of ponding <br /> water, soil clogging, odors, insects, or other potential nuisance conditions. The notations shall also <br /> document any corrective actions taken. A copy of the entries made in the log during each month shall be <br /> submitted along with monthly monitoring reports. <br /> GROUNDWATER MONITORING <br /> Prior to sampling or purging, equilibrated groundwater elevations shall be measured to the nearest 0.01 <br /> foot. The wells shall be purged at least three well volumes until pH and electrical conductivity have <br /> stabilized. Sample collection shall follow standard analytical method protocols. Groundwater monitoring <br /> shall include, at a minimum, the following: <br /> Sampling Reporting <br /> Constituent Units Type of Sample Frequency Frequency <br /> Groundwater elevation feet Measurement Quarterly Quarterly <br /> pH S.U. Grab Quarterly Quarterly <br /> Total Dissolved Solids mg/l Grab Quarterly Quarterly <br /> Fixed Dissolved Solids mg/1 Grab Quarterly Quarterly <br /> Nitrate as Nitrogen mg/1 Grab Quarterly Quarterly <br />
