impact on the water table aquifer. He said since there is separation between the
surficial aquifer and the Upper Florida Aquifer there is no impact there. He discussed
the evaporation rates and said it is replenished by rainfall. He said the sand mines
have proven that the mining operations do not have any impact on the water table
aquifer.
Mr. Allen said the sand skink studies happen closer to disturbing the land. He said they
have months of engineering and design before we get to that point. He said
non-phosphate mines are allowed in every future land use classification but
preservation. He discussed the Conditional Uses and the additional criteria that
ensures compatibility. He said they provided reports and an analysis for all of the
conditions. He said they have met those conditions and they are in compliance. He
said the decibels showed by Ms. Pratt are in acceptable ranges. He said at the Level 2
that they will do an intersection safety analysis.
Upon question, Dr. DeMott said the berm height is not relevant to the concerns about
respirable silica. He said it would be relevant to controlling the material coming off the
trucks. He said with summer storms or if there is a strong wind flow you may see those
types of conditions. He said with regards to lung cancer or silicosis it is related to daily
exposure over many years and not on occasional days when there might be wind
blown dust. He said based on the scientific literature there are no indications that we
see silicosis or lung cancer in communities near sand mining operations. He said that
data goes back into the 80's.
Upon question, Mr. Nance discussed the areas between Lake Wales and Indian Lakes
Estates. He said there are old developments that probably would not be approved
today under the rural development area or agriculture residential rural districts. He said
that there are pockets of intense development that occurred during previous zoning
rules. He said Saddlebag would be higher density.
Upon question, Matt Mouncey, applicant, said the material would stay on site for use,
reclamation and berms. He said for dust mitigation there will be the use of water trucks
to tamper it down.
Upon question, Mr. Stephens discussed the range in depths of water supply for wells.
He said there could be some residual wells that are older in the area and some are
installed to irrigate lawns. He said when talking about the groundwater flow depending
on where you are in the topography it flows out from the higher elevations. He said if
you are excavating through and into the surficial aquifer though the water table the
mining area would have had a slope on it. He said when you dig a lake the water level
becomes level. He said it will be higher on the down gradient side and lower on the up
gradient side. He discussed an environmental management plan for a mine and said it
involves what parameters you will monitor, the period of time and where you are going
to monitor those things. He said majority of that is water level in the surficial aquifer. He
said you may have ten years of baseline water level data that you can use to evaluate
the effect of the mining on the water levels.
Upon question, Mr. Allen said he has not heard of a health report on sand mines. He
said those kinds of cases are not in existence based on Dr. DeMott's report. He said
