WASTE DISCHARGE REQUIREMENTS ORDER NO. • 10- <br /> CALIFORNIA NATURAL PRODUCTS <br /> WASTEWATER TREATMENT FACILITY <br /> SAN JOAQUIN COUNTY <br /> 61. According to Pollution Abatement in the Fruit and Vegetable Industry,published by the United <br /> States Environmental Protection Agency(US EPA Publication No. 625/3-77-0007) (hereafter <br /> Pollution Abatement), in applying food processing wastewater to land for biological treatment, the <br /> loading of BODS should not exceed 100 lbs/acre/day(average)to prevent development of nuisance <br /> conditions. <br /> 62. Acidic soil conditions can be detrimental to land treatment system function, and may also cause <br /> groundwater degradation. If the buffering capacity of the soil is exceeded and soil pH decreases <br /> below 5, naturally occurring metals (including iron and manganese)may dissolve and degrade <br /> underlying groundwater. Pollution Abatement recommends that water applied to crops have a pH <br /> within 6.4 to 8.4 to protect crops from damage by food processing wastewater. Near neutral pH is <br /> also required to maintain adequate active microbial populations in the soil. <br /> 63. The California Department of Water Resources sets standards for the construction and destruction <br /> of groundwater wells (hereafter DWR Well Standards), as described in California Well Standards <br /> Bulletin 74-90(June 199 1) and Water Well Standards: State of California Bulletin 94-81 <br /> (December 1981). These standards, and any more stringent standards adopted by the State or <br /> County pursuant to CWC section 13801, apply to all monitoring wells. <br /> 64. On 15 November 2001, the City of Lathrop issued a Notice of Exemption for the installation of a <br /> pipeline in order to utilize wastewater to irrigate the 16.0 acre land application area from the <br /> provisions of the California Environmental Quality Act(CEQA),in accordance with Title 14, <br /> California Code of Regulations(CCR), Section 15301. <br /> 65. This discharge is exempt from the requirements of Consolidated Regulations for Treatment, <br /> Storage, Processing, or Disposal of Solid Waste, as set forth in Title 27, CCR,Division 2, <br /> Subdivision 1, Section 2005, et seq., (hereafter Title 27). The exemption pursuant to Section <br /> 20090(b), is based on the following: <br /> a. The Board is issuing waste discharge requirements, <br /> b. The discharge complies with the Basin Plan, and <br /> c. The wastewater does not need to be managed according to Title 22 CCR, Division 4.5, and <br /> Chapter 11, as a hazardous waste. <br /> 66. Pursuant to California Water Code Section 13263(g), discharge is a privilege, not a right, and <br /> adoption of this Order does not create a vested right to continue the discharge. <br /> PUBLIC NOTICE <br /> 67. The Board has notified the Discharger and interested agencies and persons of its intent to prescribe <br /> WDRs for this discharge and has provided them with an opportunity for a public hearing and an <br /> opportunity to submit their written views and recommendations <br /> 68.
