STATE WATER RESOURCES CONTROL BOARD - 26 - <br /> ORDER <br /> 26 - <br /> ORDER WQ 2014-0153-DWQ <br /> GENERAL WASTE DISCHARGE REQUIREMENTS <br /> FOR SMALL DOMESTIC WASTEWATER TREATMENT SYSTEMS <br /> 7. Land Application and/or Recycled Water Systems <br /> a. Wastewater shall not be applied to an LAA within 24 hours of forecasted <br /> precipitation with a greater than 50-percent probability of occurring, during <br /> precipitation events, or when the LAA surface soil is saturated. <br /> b. Spray irrigation with treated wastewater is prohibited when wind speed (including <br /> gusts) exceeds 30 miles per hour. Wind speed may be measured onsite or at a <br /> nearby weather station operated by a governmental organization. <br /> c. Discharge of wastewater from an LAA is prohibited. <br /> d. If undisinfected wastewater is applied to an LAA, storm water runoff from the LAA <br /> is prohibited. <br /> e. If storm water is allowed to runoff from an LAA (during the time of year wastewater <br /> is not applied), all applied wastewater shall meet disinfection requirements at a <br /> level equivalent to disinfected secondary-23 recycled water. (Cal. Code Regs., <br /> title 22, § 60301.225.) Land application of more highly treated water is <br /> acceptable. Alternatively, a Discharger may submit a technical report, for <br /> Executive Officer approval, describing how the LAA will be operated to prevent <br /> pathogens from migrating off the LAA with stormwater. <br /> f. If recycled water is applied, it shall comply with the title 22 water recycling criteria, <br /> this General Order, the NOA, a title 22 Engineering Report, and any DDW <br /> approval conditions. <br /> g. Public contact with wastewater/recycled water shall be precluded through use of <br /> fences, signs, and/or other appropriate means. All public use areas where <br /> recycled water is used shall be posted with signs that are visible, in a size no less <br /> than 4 inches by 8 inches and include the following wording, "Recycled Water— <br /> Do Not Drink." (Cal. Code Regs., tit. 22, § 60310(g).) <br /> h. Land application areas shall be managed to mitigate breeding of mosquitoes <br /> including, but not limited to the following: <br /> i. There shall be no standing water 48 hours after application of wastewater. <br /> ii. Tailwater ditches must be maintained essentially free of emergent, marginal, <br /> or floating vegetation. <br /> iii. Low-pressure and unpressurized pipelines and ditches accessible to <br /> mosquitoes shall not be used to store wastewater or recycled water. <br /> iv. Coordination with the local mosquito abatement or vector control district to <br /> supplement the measures described above in cases where other methods <br /> are infeasible. <br /> 8. Sludge/Solids/Biosolids Disposal <br /> a. Sludge means the solid, semisolid, and liquid residues removed during primary, <br /> secondary, or other wastewater treatment processes. Solid waste refers to grit <br /> and screenings generated during preliminary treatment. Residual sludge means <br /> September 23, 2014 <br />
