What’s in a Name? Existing New Name Manure Transfer Waste Transfer Definition Manure conveyance system Byproducts from agricultural operations Purposes Animal manure All things waste
What’s in a Name? Wastewater Manure Processing Contaminated Leachate Derivatives Runoff • milkhouse • result of treatment or • water that has • water that has • milking parlor processing touched barnyard, percolated through washwater animal lot, feed a pile of manure, • leachate • examples: storage processing • similar waste • similar waste flush water separated flush water, separated derivatives or derivatives, or sand, separated manure • generally has animal feed **wastewater from solids, digested liquids, manure, sediment, holding area is etc feed or other considered manure material in it
What’s in a Name? E i i Existing N New {tank is not used} { k i d} Tank Reception Structure Hopper Channel • never defined • collection vessel used to • sole purpose to feed • narrow structure • used used hold waste and facilitate hold waste and facilitate waste into a transfer waste into a transfer • immediate transfer to immediate transfer to throughout its transfer pump reception structures, standard • >6,000 gallon hoppers, w.s.f capacity are reception • include modified structures gutters
What’s in a Name? P Pressure Rating R i T Transfer System Pressure f S P W Working Pressure ki P Rating for pipe pipe, pipe fittings, other max. designed operating appurtenances appurtenances pressure of the transfer pressure of the transfer system max. pressure the pipe can lowest pressure rating of any 72% of the transfer system withstand without failure withstand without failure of the items listed above of the items listed above pressure rating pressure rating determined by the manufacture
General Criteria Existing New Conditions Where • Permanently installed Applicable conveyance system • Does not apply to gutters (defined as existing open (d fi d i ti troughs – think of stanchion barns) Management Assessment g Refer to 313 Components Listed p Site Assessment Refer to 313 Components Listed
General Criteria Existing New Soil Investigations Reception Structures, Channels, and Tanks Only Transfer Pipe • 1 per 40’ 1 40’ • no portion >100’ from soil ti >100’ f il • +1 per add. 80’ investigation • no more than 100’ • extend deep enough to ensure required from footprint p separation distance is achieved p • complete more if soil varies significantly • each soil investigation can be used for multiple components • logs follow new 313 criteria • logs follow new 313 criteria
Example 1
Example 2
General Criteria NEW SECTION Separation from Subsurface Saturation or Bedrock p criteria consistent with 313 separation measured from closet distance from any point on the inside surface of the component to the feature from th i id f f th t t th f t f which separation is required Perched Conditions drained via gravity system located outside the component footprint drain to surface outlet Bedrock No blasting Treat fractures or voids Min. 1% positive grade away from component
General Criteria NEW SECTION Floodplain p protect reception structures, channels, and hoppers from 25 yr 24 hr rainfall inundation structural damage instability transfer components affected by 25 yr 24 hr rainfall designed for loading (buoyancy/uplift) {companion document} evaluated for additional protections (backflow, watertight connections, auto. shutoffs) keep vents, power supplies, shutoffs out of water ff f
General Criteria Safety Safety Safety fences – refer to Fence (382) Standard design of tank cover, criteria listed design of tank cover, criteria listed ventilation of enclosed areas now required
General Criteria NEW SECTION Failure Analysis Failure Analysis evaluate entire design address issues address issues during the design phase O&M E Emergency Response Plan R Pl be sure to document the analysis and decisions made
General Criteria Construction Plans and Specifications Construction Plans and Specifications Existing New Vague Specific • only required • must include maximum • location map an inspection an inspection design working pressure design working pressure • plan view • plan view plan • profiles • transfer system • cross sections pressure rating • details and specs to ensure it can be built correctly
General Criteria NEW SECTION Engineering Design Documentation Engineering Design Documentation follow Statement of Work (efotg) includes all data, computations, assumptions includes all data, computations, assumptions must prove you have met the standard
General Criteria NEW SECTION Quality Assurance Plan {formally known as Inspection} Quality Assurance Plan {formally known as Inspection} required for each construction plan specifically lists required items specifically lists required items site info. key Parties testing/Observations/etc.
General Criteria Operation and Maintenance Operation and Maintenance Existing New refer to 313 Specific • must be reviewed with • general system overview landowner/operator landowner/operator • safety and emergency response • safety and emergency response • specific for each • operating procedures, pump start up/downs component • maintenance item schedule • detail maintenance items
