Current through June 17, 2024
007.01
  Livestock Truck Washes
007.01A Livestock
  truck washes will either connect to a public sanitary sewer system or to a
  wastewater works designed and constructed according to the following standards.
007.01B Livestock truck washes
  will include wash pads that capture all wash water from the washing operation
  and convey it to the wastewater works. Wash pads will be constructed of
  concrete or another impermeable material.
007.01C One of the following wastewater
  systems will be used for livestock truck washes.
1) A complete retention facultative lagoon
  system.
2) A wastewater storage
  pond and land application system.
3) A solids separation system, wastewater
  storage pond and land application system.
4) Another system proposed by the owner and
  approved by the Department.
007.01D Lagoons and storage ponds used for
  truck washes will meet the design standards and testing requirements in Chapter
  5, 005.
007.01E Wastewater
  facilities designed to separate solids from the wash water for separate
  handling and disposal will include a settling pit and a solids storage unit as
  specified below.
007.01E1 Solids settling
  pits will be constructed of concrete and will be watertight. Pits will have at
  least 24-hour detention time and be designed to contain both floatable and
  settleable solids. The design will include a method to remove solids from the
  pit.
007.01E2 Solids storage units
  will be watertight structures designed to dry and store solids removed from
  solids settling pits. A drain system will return surplus water back to the
  solids settling pit or to the lagoon. At least 120 days of solids storage will
  be provided with controls to prevent storm water run off.
007.01F The hydraulic design of the WWTF will
  be based on historic flow records from other facilities using similar washing
  equipment. Where verifiable flow records do not exist, a flow not less than
  1500 gallons per truck washed will be used for design.
007.01G The solids handling capacity will be
  based on data from similar facilities or on specific data from the owner's
  operation, such as the size of animals, the length of trips, the type of
  bedding material, and manure production rates. In the absence of specific data,
  the design will assume ten cubic feet of solids (bedding and manure) generated
  from each truck washed.
007.01H
  Livestock truck washes will receive written approval, including site approval,
  from the Department prior to land applying wastewater or wastewater solids.
007.01I Irrigation piping networks
  used to apply lagoon water will be equipped with check valves, vacuum relief
  valves, and low pressure drains, as necessary, to protect ground water wells or
  other sources or irrigation water from contamination from the back flow of
  lagoon water.
007.01J Livestock
  truck wash projects that are submitted for approval must include a written
  management plan adequate to prevent chemical tank trucks, garbage trucks,
  septage haulers, or other vehicles that could contain hazardous, toxic, or
  pathogenic wastes from using the livestock truck wash. Any security devices or
  structures described in the management plan to regulate usage must be shown on
  the plans submitted for approval.
007.01K A livestock truck wash that was
  reviewed and approved by the Department as part of an animal feeding operation
  (AFO) that has received approval for the livestock waste control facility under
  Title 130, Livestock Waste Control Regulations, is exempt from the construction
  permit requirements of this Title.
