ATTACHMENT C— INFORMATION SHEET C-7 <br /> MODEL MONITORING AND REPORTING PROGRAM <br /> STATE WATER RESOURCES CONTROL BOARD <br /> ORDER WQ 2014-0153-DWQ <br /> GENERAL WASTE DISCHARGE REQUIREMENTS <br /> FOR SMALL DOMESTIC WASTEWATER TREATMENT SYSTEMS <br /> Constituent Units Sample Sample Reporting <br /> Type Frequency Frequency <br /> Total Nitrogen a mg/L Grab Monthly Quarterly <br /> mg/L denotes milligrams per liter. <br /> a. Include nitrogen monitoring when a nitrogen effluent limit is imposed. <br /> DISINFECTION SYSTEM MONITORING <br /> If disinfection is performed, samples shall be collected from immediately downstream of the <br /> disinfection system. Depending upon the level of disinfection and wastewater disposal, <br /> monitoring requirements vary. Disinfection monitoring shall be customized to the site-specific <br /> conditions from the following: <br /> Constituent Units Sample Sample Reporting <br /> Type Frequency Frequency <br /> Total Coliform Organisms MPN/100 mL Grab TBD a Quarterly <br /> Turbidity NTU Grab/Meter TBD a Quarterly <br /> MPN/100 mL denotes most probable number per 100 mL sample. NTU denotes nephelometric turbidity unit. <br /> a. TBD (to be determined) shall be specified in the NOA or as required by California Code of Regulations, <br /> title 22 section 60321. <br /> RECREATIONAL VEHICLE DISCHARGE MONITORING <br /> Any wastewater system that has accepted recreational vehicle, portable toilet, or similar <br /> waste in the previous 12 months shall perform the following additional monitoring. Samples <br /> shall be collected to characterize effluent that is stored in wastewater ponds or that will be <br /> applied to a disposal area. Wastewater shall be monitored as specified below: <br /> Constituent Units Sample Type Sample Reporting <br /> Frequency Frequency <br /> Zinc mg/L Grab Quarterly Quarterly <br /> Phenol mg/L Grab Quarterly Quarterly <br /> Formaldehyde mg/L Grab Quarterly Quarterly <br /> mg/L denotes milligrams per liter. <br /> SUBSURFACE DISPOSAL AREA <br /> Subsurface disposal areas may be configured many different ways (e.g. traditional leach <br /> field, pressure-dosed, drip system, mound/at grade, gravel less, etc.). In general, monitoring <br /> shall be sufficient to determine if wastewater is evenly applied, the disposal area is not <br /> saturated, burrowing animals and/or deep rooted plants are not present, and odors are not <br /> present. Inspection of dosing pump controllers, automatic distribution valves, etc. is required <br /> to maintain optimum treatment in the disposal area (and any sand or media filter if present). <br /> Monitoring shall include, at a minimum, the following: <br /> September 23, 2014 <br />
