Status of Construction of the 240 Poultry Houses Approved 11
GROUNDWATER WITHDRAWAL Community Concern • 2016 Poultry Report indicated that 129,000 gallons of water would be to support a poultry house for seven (7) weeks. • The 129,000 gallons of water is a solid number for poultry consumption (drinking) water usage, and has been confirmed by metered use in a newly constructed poultry house. The usage #s are representative for the new poultry houses only. • Cooling water was not accounted for in the 2016 report. • Recently, there has been significant concern over the amount of groundwater needed for poultry cooling water NOTE: The usage #s are representative for the new poultry houses only. 12
GROUNDWATER WITHDRAWAL cont.’ Consumption Water Usage (by month/per house) – Staff Estimates 129,000 gallons per flock x 5.5 flocks per year = 709,500 gallons per year 709,500 gallons per year ÷ 12 months = 59,125 gallons per month per house for consumption 13
GROUNDWATER WITHDRAWAL cont.’ Cooling Water Usage (by month/per house) – Staff Estimates • High Range (Circulating through the community) 7,500 gallons per day x 30 day s = 225,000 gallons per month (gpm) 225,000 gpm x 5 months where cooling is needed = 1,125,000 gallons per house/ per year 93,750 gallons 1,125,000 gallons per house per year ÷ 12 months = per month per house Cooling HIGH RANGE Mid Range (Derived from University of Georgia Report Dated 2017) • 2.5 gallons per minute (summer cooling) 2.5 gallons per minute x 60 minutes/per hour = 150 gph 150 gph x 12 hrs (max per day) = 1,800 gpd 1,800 gpd x 30 days = 54,000 gallons per month (gpm) 54,000 gpm x 5 warm months where cooling is needed = 270,000 gallons per year (gpy) 22,500 gallons 270,000 gpy ÷ 12 months = per month per house 14 Cooling MID RANGE
GROUNDWATER WITHDRAWAL cont.’ Cooling Water Usage (by month/per house) – Staff Estimates • Low Range (20% of Consumption Use/Year Round) 709,500 gallons per year x 20% (cooling water required) = 141,900 cooling gallons per year 11,825 gallons 141,900 cooling gallons per year ÷ 12 months = per month per house Cooling LOW RANGE CONSUMPTION PLUS COOLING GALLONS PER MONTH PER HOUSE 59,125 + 11,825 = 70,950 GPM/PER POULTRY HOUSE – Low Range 59,125 + 22,500 = 81,625 GPM/PER POULTRY HOUSE – Mid Range 59,125 + 93,750 = 152,875 GPM/PER POULTRY HOUSE – High Range 15
GROUNDWATER WITHDRAWAL cont.’ At the February 21, 2018 Board of Supervisors meeting, Tyson representatives announced that they intend to pull cooling water from the upper aquifer where possible on poultry operations where wells have not yet been drilled. They also suggested that they were going to try to retro-fit some of the recently completed poultry operations. In both instances, site groundwater conditions (availability & reliability of the upper aquifer ) will determine feasibility. Tyson did NOT announce that it would be pulling its consumption (drinking water) from the upper aquifer. 16
GROUNDWATER WITHDRAWAL cont.’ • A groundwater withdrawal permit is required from the DEQ for groundwater withdrawals that exceed 300,000 gallons per month, as reported in the 2016 report. • A groundwater withdrawal permit is required whether the withdrawal is from the lower, mid or upper aquifer. • No groundwater permits for long-time existing or new confined poultry operations have been issued by DEQ at this time. • The following slide is provided related to groundwater withdrawal applications filed in the last year. PLEASE NOTE THAT THE FOLLOWING CHART REFERS TO ZONING PERMIT #S, NOT POULTRY HOUSE NUMBERS , IN ORDER TO CORRELATE TO THE DEQ INFORMATION. 17
