MONITORING AND REPORTING PROGRAM No. R5-2013-0122 MRP-2 GENERAL ORDER FOR EXISTING MILK COW DAIRIES A. MONITORING REQUIREMENTS Visual Inspections The Discharger shall conduct and record the inspections specified in Table 1 below and maintain records of the results on-site for a period of five years. Table 1. INSPECTIONS Production Area Weekly during the wet season 0 October to 30 April) and monthly between 1 May and 30 September: Inspect all waste storage areas and note any conditions or changes that could result in discharges to surface water and/or from property under control of the Discharger. Note whether freeboard within each liquid storage structure is less than, equal to, or greater than the minimum required (two feet for above ground ponds and one foot for below ground ponds). During and after each significant storm event': Visual inspections of storm water containment structures for discharge, freeboard, berm integrity, cracking, slumping, erosion, excess vegetation, animal burrows, and seepage. Monthly on the 1St day of each month: Photograph each pond showing the height of wastewater relative to the depth marker and the current freeboard on that date. All photos shall be dated and maintained as part of the discharger's record. Land Application Areas Prior to each wastewater application: Inspect the land application area and note the condition of land application berms including rodent holes, piping, and bank erosion. Verify that any field valves are correctly set to preclude off-property or accidental discharges of wastewater. Daily when process wastewater is being applied: Inspect the land application area and note the condition of land application berms including rodent holes, piping, and bank erosion; the presence (or lack)of field saturation, ponding, erosion, runoff (including tailwater discharges from the end of fields, pipes, or other conveyances), and nuisance conditions; and the conditions of any vegetated buffers or alternative conservation practices. A significant storm event is defined as a storm event that results in continuous runoff of storm water for a minimum of one hour, or intermittent runoff for a minimum of three hours in a 12-hour period. Nutrient Monitoring The Discharger shall monitor process wastewater, manure, and plant tissue produced at the facility, soil in each land application area, and irrigation water used on each land application area for the constituents and at the frequency as specified in Table 2 below. This information is for use in conducting nutrient management on the individual land application areas and at the facility on the whole. It must be used to develop and implement the Nutrient Management Plan. The Discharger is encouraged to collect and use additional data, as necessary, to refine nutrient management.
