WASTE DISCHARGE REQUMAL S ORDER NO. GOLDSTONE LAND COMPANY, LLC AND KURT KAUTZ BEAR CREEK WINERY SAN JOAQUIN COUNTY pollutants that, under ambient environmental conditions at a waste management unit, could be released in concentrations exceeding applicable water quality objectives or that could reasonably be expected to affect beneficial uses..." 57. Consolidated Regulations for Treatment, Storage, Processing, or Disposal of Solid Waste, as set forth in Title 27, California Code of Regulations, §20005 et seq., specify types of waste that must be fully contained and prescribes standards for containment, including for designated waste. 58. Title 27, §20210, specifies criteria for containment and disposal of designated waste constituents on land. Liquid designated waste in surface impoundments is subject to full containment with double liners in accordance with standards prescribed in Title 27. Land treatment of designated waste is subject to standards prescribed by Title 27 for a Class I or Class II LTU. Title 27, §20164, defines an LTU as a`waste management unit (Unit) at which liquid and solid waste is discharged to, or incorporated into, soil for degradation, transformation, or immobilization within the treatment zone." It defines treatment zone as "a soil area of the unsaturated zone of a LTU within which constituents of concern are degraded, transformed, or immobilized." 59. Designated waste subject to the Title 27 prescriptive and performance standards for an LTU may qualify for conditional exemption from Title 27 pursuant to §20090(b). A discharge of decomposable waste that need not be managed as a hazardous waste can be exempted under §20090(b) if all waste constituents are treated and controlled to a degree that the discharge complies with the Basin Plan. Documentation for such exemption must at least equal the scientific rigor of the test plot required as a prerequisite of approval of a Title 27 LTU. 60. Performance standards of Title 27 applicable to LTUs require that: a. Prior to discharge, the Discharger must demonstrate that the LTU can completely degrade transform, or immobilize designated waste constituents in the treatment zone, not to exceed five feet below the initial ground surface(§20250(6)); b. Prior to discharge, the Discharger must establish the appropriate design depth of the treatment zone for each designated waste constituent,not to exceed five feet below the initial ground surface (§20250(b)); c. Prior to discharge, the Discharger must establish a site-specific Water Quality Protection Standard(§20390) for each designated waste constituent (§20395),the concentration limits (§20405), and the Point of Compliance and all Monitoring Points (§20405); d. Specific standards are prescribed by which to monitor water quality(§20420), including a detection monitoring program(§20420), an evaluation monitoring program(§20425), and an unsaturated zone monitoring program for the LTU (§20435),which requires soil-pore liquid monitoring to ensure effective operation. 61. Pursuant to §20090(b), the Board may exempt a discharge from Title 27 only if: a. The Regional Board issues waste discharge requirements; V:�San laagwn_Nont SSufflObricnTProjen Filez\Bcu Gak\WDREx
