<p> November 2008 WASTE TREATMENT </p><p>PRACTICE INTRODUCTION</p><p>USDA, Natural Resources Conservation Service―Practice Code 629</p><p>WASTE TREATMENT COMMON ASSOCIATED PRACTICES Waste treatment is the mechanical, chemical, or Waste Treatment is commonly used in a biological treatment of agricultural waste. Conservation Management System with the following practices: PRACTICE INFORMATION  Waste Storage Facility (313) The purpose of the practice is to change the form  Waste Treatment Lagoon (359) or composition of waste as part of an agricultural waste management system. The composition or  Waste Transfer (634) form of the waste is modified to provide additional  Subsurface Drain (606) utilization alternatives. This includes the  Heavy Use Area Protection (561) separation of liquids and solids (e.g., milk room waste) for further processing or for effective  Wastewater Treatment Strip (635) transport and subsequent utilization or treatment in For further information, refer to the practice a subsurface drain field; the dilution of raw standard in the local Field Office Technical Guide agricultural waste (e.g., silage leachate), which and associated specifications and job sheets. contains excess or unavailable nutrients for land application based on crop utilization requirements. Value added by-products can be produced to offset treatment costs. Planned mitigating practices include Pest Management (595), Nutrient Management (590), and Waste Utilization (633).</p><p>The following page identifies the effects expected to occur when this practice is applied. These effects are subjective and somewhat dependent on variables such as climate, terrain, soil, etc. All appropriate local, State, Tribal, and Federal permits and approvals are the responsibility of the landowner and are presumed to have been obtained. Users are cautioned that these effects are estimates that may or may not apply to a specific site.

These effects are subjective and somewhat dependent on variables such as climate, terrain, soil, etc. All appropriate local, State, Tribal, and Federal permits and approvals are the responsibility of the landowners and are presumed to have been obtained. All income changes are partially dependent upon market fluctuations which are independent of the conservation practices.
