(a) Authorization. Council hereby authorizes the surface application of brine to roads, streets, highways and other similar land surfaces that the City owns or has the right to control, for the control of dust or ice.
(b) Guidelines. Council hereby adopts the following guidelines for the application of brine to roads, streets, highways and other similar land surfaces under the control of the City:
(1) Brine shall not be applied:
A. To a water-saturated surface;
B . Directly to vegetation near or adjacent to surfaces being treated;
C. Within twelve feet of structures crossing bodies of water or crossing drainage ditches; or
D . Between sundown and sunrise, except for ice control.
(2) The discharge of brine through the spreader bar shall stop when the application stops.
(3) The applicator vehicle shall be moving at least five miles per hour at all times while the brine is being applied.
(4) The maximum spreader bar nozzle opening shall be three-quarters of an inch in diameter.
(5) The maximum uniform application rate of brine shall be 3, 000 gallons per mile on a twelve-foot wide road or three gallons per sixty square feet on unpaved lots.
(6) The applicator vehicle discharge valve shall be closed between the brine collection point and the specific surfaces that have been approved for brine application.
(7) Any valves that provide for tank draining, other than through the spreader bar, shall be closed during the brine application and transport.
(8) The angle of discharge from the applicator vehicle spreader bar shall not be greater than sixty degrees from the perpendicular to the unpaved surface. Only the last twenty-five percent of an applicator vehicle's contents shall be allowed to have a pressure greater than- atmospheric pressure; therefore, the first seventy-five percent of the vehicle's contents shall be discharged under atmospheric pressure.
(c) Future Contracts. The Director is hereby directed to make the guidelines set forth in subsection (b) hereof part of any contract that is later entered into between the City and any third party for the purpose of applying brine to roads, streets, highways and other similar land surfaces it owns or has a right to control.
