EVALUATION AND RECOMMENDATIONS
1. Provide any additional narrative regarding your review of the application.: The Town of Angier
currently operates two( 2) wastewater treatment systems. One is permitted under NPDES Permit #
NC0082597 which is permitted to discharge .5 MGD into a receiving stream. The other treatment
system is the one which the Town has requested to be renewed:This is a land application/spray
irrigation system permitted to land apply 258,000 GPD to 46 acres of land. The subject system is only
utilized durning wet conditions due to the Town of Angier's extreme I/I problems. In the summer
months the spray system typically has little to no flow. Raw wastewater is only diverted to this
facility so that the NPDES facility does not exceed its design flow. The Town wishes to retain this
Permit for the above reasons. The subject facility was first permitted in the late 1980's and was built
from a 201 Grant issued through our Construction Grants & Loans Section.The system has not
changed _since it was origionally issued. This is a 100% renewal application.
2. List any items that you would like NDPU to obtain through an additional information request. Make
sure that you provide a reason for each item:
Item
Reason
3. List specific Permit conditions that you recommend to be removed from the permit when issued.
Make sure that you provide a reason for each condition:

4. List specific special conditions or compliance schedules that you recommend to be included in the
permit when issued. Make sure that you provide a reason for each special condition:
