WASTE DISCHARGE REQUIREMENTS ORDER NO. -9- CALIFORNIA NATURAL PRODUCTS WASTEWATER TREATMENT FACILITY SAN JOAQUINCOUNTY 55. Section 13267(b) of California Water Code provides that: "In conducting an investigation specified in subdivision (a), the regional board may require that any person who has discharged, discharges, or is suspected of having discharged or discharging, or who proposes to discharge waste within its region, or any citizen or domiciliary, or political agency or entity of this state who has discharged, discharges, or is suspected of having discharged or discharging, or who proposes to discharge, waste outside of its region that could affect the quality of waters within its region shall furnish, under penalty of perjury, technical or monitoring program reports which the regional board requires. The burden, including costs, of these reports shall bear a reasonable relationship to the need for the report and the benefits to be obtained from the reports. In requiring those reports, the regional board shall provide the person with a written explanation with regard to the need for the reports, and shall identify the evidence that supports requiring that person to provide the reports. " The monitoring and reporting program required by this Order and the attached Monitoring and Reporting Program No. are necessary to assure compliance with these WDRs. The Discharger operates the facility that discharges the waste subject to this Order 56. Excessive application of food processing wastewater to land application areas can create objectionable odors, soil conditions that are harmful to crops, and degradation of underlying groundwater by overloading the shallow soil profile and causing pollutants (organic carbon, nitrate, dissolved solids, and metals) to percolate below the root zone. If sufficient information becomes available, this Order may be revised to increase or further reduce loading rates as appropriate. If the Discharger is unable to modify its waste stream or application methods such that groundwater quality will not be impacted, then the Regional Board would be required to classify the waste as a designated waste and require full containment under Title 27 of the California Code of Regulations (hereafter Title 27). 57. State regulations pertaining to water quality monitoring for waste management units are found in Title 27, California Code of Regulations (CCR), Section 20380 et seq., (hereafter Title 27). These regulations prescribe procedures for detecting and characterizing the impact of waste constituents on groundwater. While the facility has been found exempt from Title 27, the data analysis methods of Title 27 are appropriate for determining whether the discharge complies with the terms for protection of groundwater specified in this Order. 58. According to Pollution Abatement in the Fruit and Vegetable Industry,published by the United States Environmental Protection Agency(US EPA Publication No. 625/3-77-0007) (hereafter Pollution Abatement), in applying food processing wastewater to land for biological treatment, the loading of BODS should not exceed 100 lbs/acre/day(average) to prevent development of nuisance conditions. 59. Acidic soil conditions can be detrimental to land treatment system function, and may also cause groundwater degradation. If the buffering capacity of the soil is exceeded and soil pH decreases below 5, naturally occurring metals (including iron and manganese)may dissolve and degrade underlying groundwater. Pollution Abatement recommends that water applied to crops have a pH V,\ an_Joaquin Non l5\Slali\ObrivnTSan Joaquin\Cal_Nat_Produces\WDR O]W\WDR July US.doc
