1. Are there appropriately certified Operators in Charge (ORCs) for the facility? ❑ Yes ❑ No ® N/A
WWTP ORC: SI ORC: Certificate #: This is a distribution permit for Class A material
and currently Certified Operators are not required for all distribution activities: however, the Permittee contracts
with US Biosolids Inc. (formerly Southern Soil Builders) for land application events.
2. Are the design, maintenance and operation of the treatment facilities adequate for the type of waste and disposal
system? ® Yes or ❑ No
If no, please explain:
Description of existing facilities: Alum residuals are stored onsite in a 400,000 g tank until land applied or
properly disposed. In August 2020 disposal was managed by Eagle Dynamic Solutions. LLC out of Georgia. The
last land application event was in 2016.
Proposed flow:
Current permitted flow: NA — This is a Class A WTP Distribution Permit for 200 Dry Tons annually. They only
produce around 25 Dry Tons/Yr., but have capacity in the holding tank for approx. 3 years of storage between
distribution/application events.
Explain anything observed during the site visit that needs to be addressed by the permit, or that may be important
for the permit writer to know (i.e., equipment condition, function, maintenance, a change in facility ownership,
etc.)
3. Are the site conditions (e.g., soils, topography, depth to water table, etc.) maintained appropriately and adequately
assimilating the waste? ❑ Yes or ❑ No NA — This is a WTP non-503 residuals permit, specific fields and
maps are not required.
If no, please explain:

If no, please explain:
6. Are the existing application rates (e.g., hydraulic, nutrient) still acceptable? ❑ Yes or ® No
If no, please explain: Change with % Solids and application site. Lab analyses are due for all parameters prior to
the next distribution/land application event.
7. Is the existing groundwater monitoring program adequate? ❑ Yes ❑ No ® N/A
If no, explain and recommend any changes to the groundwater monitoring program:
