(c) Water Utility Use. 1. Initial pressure at the point of use (meter) shall be reduced to levels no greater than 45 pounds per square inch. Voluntary initial pressure reductions below 45 psi shall be made consistent with the utility’s ability to maintain adequate service and fire flow pressures. Upon reduction of pressure, the utility shall notify the appropriate fire-fighting agencies and make arrangements for direct communication when additional pressure is required. 2. New water line flushing and disinfection shall be restricted to the hours of 7:00 P.M. to 7:00 A.M. seven days per week. 3. As may be appropriate the utility shall institute additional voluntary conservation measures such as reclaiming of backwash water, improving and accelerating leak detection surveys and repair programs, installing and calibrating meters, and stabilizing and equalizing system pressures. (d) Power Production Use. 1. Water used for power production shall be voluntarily reduced. (e) Commercial and Industrial Process Use. 1. Commercial car washes shall be restricted as follows: a. For washes servicing passenger vehicles and mobile equipment weighing less than 10,000 pounds, i. Use in excess of 75 gallons per wash shall be prohibited, ii.

Overhead irrigation shall be restricted to the hours of 7:00 P.M. to 7:00 A.M. 2. Low volume irrigation hours shall not be restricted. 3. Allirrigation systems shall be operated in a manner that will maximize the percentage of water withdrawn and held which is placed in the root zone of the crop and will minimize the amount of water which is withdrawn and released or lost to the user but is not immediately available for other users. 4. Users having access to more than one source class shall maximize the use of the lesser or least restricted source class. 5. Withdrawals by each user from each source class in each month shall be limited to an amount that represents each user’s share of the total allocation for agricultural irrigation made by the District from that source for that month and in that basin. The District’s allocation determination for agricultural irrigation will be based on its evaluation of the supply capabilities of the source class, the supply capabilities of other source classes available in the area, the needs of agriculture and all other users in the area and the District’s overall management strategy for handling the uncertainties of future climatological events. The share of the total agricultural irrigation allocation available to each user will be based on any prioritization among crops the District establishes based on irrigation efficiency, economic loss and equity considerations and the acreage and quantity of withdrawals for which the user has been permitted. The District’s allocation determination for agricultural irrigation within the Lake Okeechobee Region, as described in subsection 40E-21.691(3), F.A.C., will be based on the supply capacity of Lake Okeechobee as defined by the establishment of a temporary revised reference elevation. In making the determination the District will consider the following: a. The short and long term harm to the water resources and economy associated with further reduction in Lake stage; b. The harm to the crops, and associated economic impacts, projected to result from the reduction or elimination of water supply; and c. The projected drought duration. The day to day operational decisions associated with implementing the temporary revised reference elevation shall be delegated to staff in the Phase III water shortage order. The governing board will be updated on a monthly basis at a governing board or other public meeting of past and projected changes to the temporary revised reference elevation. 6.
