If yes, please explain:
2. List any items that you would like the NPDES Unit or Non -Discharge Unit Central Office to obtain through an
additional information request:
Item
Reason
3. List specific permit conditions recommended to be removed from the permit when issued:
Condition
Reason
Assess sampling
requirements in
Attachments A & C
Nutrient and phosphorus results historically low. How long do we assess /
impose expense on permittee?
4. List specific special conditions or compliance schedules recommended to be included in the permit when issued:
Condition
Reason
Assessment of the lagoons'
clay bottom and
concrete/fabric apron.
Age of facility warrants Engineer assessment for lagoon integrity. ORC noted
in 2020 inspection — fibers from the concrete/fabric apron have caused
equipment damage in the treatment works.
Assess septic tank, lagoon
and clear well solids and
remove as needed.
Typical recommendation.
5. Recommendation: n Hold, pending receipt and review of additional information by regional office
® Hold, pending review of draft permit by regional office
n Issue upon receipt of needed additional information
