A. Staff Report/Inspection:
During our review of the renewal application and subsequent facility inspection, our Regional
Office staff noted that a chemical feed was added to the treatment system. Available information
on this chemical feed was limited, and our office does not have any records of a minor modification
being submitted for review. Changes to the treatment system (including the addition of chemical
feeds) require a minor modification of the permit. Please provide information regarding chemical
type, chemical dosing, chemical storage, equipment location and sizing, and piping and other
appurtenance information related to the chemical feed system. Please submit the application form
HRIS 06-16, signed and sealed engineering calculations, plans, and specifications pursuant to 15A
NCAC 02T .0704. Our understanding is that this equipment has already been installed, as such
please also provide the date it was installed, an executed engineering certification, and the updated
Operation and Maintenance (O&M) and Residuals Management Plans.
