This letter is to follow -tip to our meeting at your office on August 12, 1992. (Christianne C.
Farraro, P.E. was also in attendance.)
The meeting dealt with a review of the proposed cattle grazing operation for Site 10 and (lie
report we prepared on August 11, 1992, addressing runoff.water quality related to cattle grazing
on improved and native pastures. Cattle grazing would be in addition to the citrus operation
and hay harvesting already permitted for the site.
We hereby request modification to the above - referenced permit to allow a cow /calf operation
on the Site 10 hay crop area based on the following conditions:
1. The cattle operation shall be limited initially to one mature cow or heifer per
three acres of improved pasture. Later adjustments of stocking rates"will be
considered after the first six montlis to one year of cattle operation, and will be
based upon forage volume and runoff water quality testing.
2. We will provide additional testing in selected ponds for an interim period before
cattle arc introduced to help establish a baseline for:
A. Non - irrigated pasture areas - Pond B -2
B. Irrigated areas (Citrus) - Pond E -1
C. Natural undeveloped areas (the woods in Eagle Protection Area I{1).

Testing will be done bi- monthly until effluent is applied, then quarterly for one
year after the effluent and cattle operation has begun. After the first year of
operation, the testing program will be reviewed for reduction to the current
permit requirements. (Quarterly in Pond B -2)
The following test parameters shall be as stated in the permit monitoring plan.
A. Fecal Coliforms
B. Total Keldgal Nitrogen
C. Nitrate Nitrogen
D. Total Phosphorus
E. PH
3. The following Best Management Practices shall be incorporated into the lease for
the cattle operation.
1. Control the location of supplemental feeding areas and other areas where
cattle will be collected, to areas away or buffered from the wetlands and
the main drainage system collection ditches.
2. Fertilize the pasture solely based.on leaf analysis in order to supplement
deficiencies not supplied in sufficient quality in the effluent.
3. Fence off the stormwater holding areas.
4. Fence off selected wetlands that are connected to offsite drainage where
they are not first intercepted or buffered by the onsite drainage system.
5. Control grazing density and timing to prevent over grazing and excess
dung deposition.
