The existing manure management system is adequate for the existing facilities and operations.
<br /> necessary to accommodate this growth.
<br /> The expansion of herd population at Phase I through Phase IV will require site improvements
<br /> • Phase /— In phase one (fall 2003) install a state of the art milking parlor, a well, and two state
<br /> of the art freestall barns to accommodate a population of 960 lactating cows. Replace the
<br /> existing settling pond with a new settling pond and extend the lagoon. Install a manure solids
<br /> storage area, and install a manure water irrigation system with drain ditches and return system
<br /> designed to control all onsite water.
<br /> • Phase //—(spring 2005) install two additional freestall barns and a well to bring lactating cow
<br /> - population to 1310. Install a new settling pond.
<br /> • Phase ///— (spring 2007) install two additional freestall barns to bring lactating cow population
<br /> to 1665.
<br /> • Phase /V— (spring 2008) install two additional freestall barns to bring lactating cow population
<br /> to 1900.
<br /> - The projected capacity required at this facility (based on a six month storage of manure effluent,
<br /> milk parlor water and rainfall runoff) to ensure the maximum volume can be retained on site is
<br /> 10,364,203 gallons (Phase 1), 13,595,590 gallons (Phase II); 17,034,478 gallons (Phase III); and
<br /> adding the 3.4 inches from a 25 year 24 hour storm is 2,630i 105 A gallons (Phase 1), 3,212,889 B
<br /> gallons (Phase 11), 3,555,172 B gallons (Phase III), resulting n a total volume of manure effluent to
<br />— be 12,994,308 gallons (Phase 1), 16,808,479 gallons (Phase 11); and 20,589,650 gallons (Phase
<br /> III). The projected capacities required for Phase IV,
<br /> gallons 4,009,452 B gallons, and 19,177,162 gallons. based on 120 day storage c, are 15,167,710

<br /> Storage Capacity
<br /> Notes:
<br /> A. For Phase I, Capacity of lagoon is sufficient to retain all liquids. Settling pond will not be
<br /> needed for winter rainfall storage.
<br /> B. Capacity includes storage for one settling pond, in lieu of two ponds. The design of settling
<br /> ponds is to retain the solids, and the liquids will overspill from one pond to the other; then to
<br /> the flush lagoon. Therefore, both ponds will never be full simultaneously. Refer to Effluent
<br /> Calculations, Appendix F.
<br /> C. Note that Phase IV is calculated for 120 day storage of manure effluent, milk parlor water
<br /> and rainfall runoff, as required by the State Water Quality Control Board.
