WASTE DISCHARGE REQUIREMENTS ORDER NO.R5-2002-0034 7 SUTTER HOME WINERY LODI FACILITY,SAN JOAQUIN COUNTY 43. State t regulations pertaining to water quality monitoring for waste management units are found in Title 27, California Code of Regulations (CCR), Section 20380 et scq., (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.protectiorvof°groundwater specified iii this Order: -' 44. 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. 45. 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 within 6.4 to 8.4.to protect crops from damage by food processing wastewater. Near neutral pH is also required to maintain adequate active microbial populations in the soil. 46. The California Department of Water Resources sets standards for the construction and destruction of groundwater wells (hereafter DWR Well Standards), as described in California Well Standards Bulletin 74-90(June 1991) and Water Well Standards: State of California Bulletin 94-81 (December 1981). These standards, and any more stringent standards adopted by the State or County pursuant to CWC section 13801, apply to all monitoring wells. 47. Federal regulations for stormwater discharges were promulgated by the U.S. Environmental Protection Agency on 16 November 1990 (40 CFR Parts 122, 123, and 124). The regulations require specific categories of facilities which discharge stormwater associated with industrial activities to obtain NPDES permits. Sutter Home Winery's operation has a Standard Industrial Classification Number of 2084 and therefore the Discharger is required to apply for a stormwater NPDES permit. 48. On 10 June 1998, San Joaquin County Community Development Department issued a Negative Declaration for this project, in accordance with the California Environmental Quality Act (CEQA) (Public Resources Code Section 21000, et seq.) and the State CEQA Guidelines. 49: This discharge is exempt from the requirements of Consolidated Regulations for Treatment, Storage, Processing, or Disposal of Solid Waste, as set forth in Title 27, CCR, Division 2, Subdivision 1, Section 2005, et seq., (hereafter Title 27). The exemption pursuant to Section 20090(b), is based on the following: a. The Board is issuing waste discharge requirements, b. The discharge complies with the Basin Plan, and
