Title
PLN2021-0030 - Silva's Holsteins Dairy
Description
Request to expand an existing dairy facility, operating on two parcels totaling 124± acres, in the General Agriculture (A-2-40) zoning district, by expanding the herd from 1,095 mature cows (880 milk and 215 dry cows) to 2,200 mature cows (1,900 milk and 300 dry cows); and to increase support stock numbers by 1,015, from 885 to 1,900 heifers. The proposed support stock will consist of 600 heifers, 15-24 months old; 600 heifers, 7-14 months; 350 calves, 4-6 months old; and 350 calves, 0-3 months. The total number of animal units is to increase by 2,120. Consequently, additional waste will be generated. The dairy‚Äôs existing Waste Management plan (WMP) and Nutrient Management Plan (NMP) were revised to account for the increase in waste and resulting storage and disposal needs associated with the increase in herd size. The updated WMP estimates that the expansion will increase the daily manure production by 3,135 cubic feet, for a total of 5,889 cubic feet of manure per day, which equates to approximately 10,588,324 gallons and 1,415,453 cubic feet of manure per year (pre-separation). The estimated wastewater storage needs will be accommodated by the existing capacity of the on-site lagoons.
