V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
It wears field PO-09-1 and 2 meet the setback requirements established under 02T.1108. No apparent slopes rg eater
than 10% exist in either field. Ownership records on Polk County GIS corresponded to the signed landowner
agreements. It is recommended that Synagro label the setbacks illustrated on the field maps with the actual distances.
Inspectors assume the wells shown are buffered 100' and the houses are buffered 400' from the proposed land
application area. Polk County GIS depicted what appears to be a drainageway within field PO-09-2 (F-2); however,
inspectors did not observe a swale or ditch at the time of the site visit. No surface waters or ditches were apparent in
either field. See the add -info request above regardingthe he depression/debris pile in the northern portion of field PO-09-
2. Recommend excluding this of the field from the application area unless debris is removed, the area is
regraded, and a crop is established. A cattle watering station is in the eastern portion of PO-09-2. While not required,
its recommended that this area be buffered since there is a concrete slab underneath.
