Subject: Draft NPDES Permit Renewal
Permit NC0025402
Enfield WWTP
Halifax County
Grade IV Biological WPCS
SIC Code 4952
Dear Mr. Anderson:
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please
review this draft carefully to ensure thorough understanding of the requirements and conditions it
contains. Changes made to the draft permit sent to you on November 10, 2020 are outlined below.
On December 1, 2020, the Town of Enfield submitted comments requesting the facility not be
rerated as a Grade IV facility, with the rationale that the facility's total nitrogen and total
phosphorous load limits are part of an overall basin group limit. However,The Tar-Pamlico Basin
Association group limit allows for some leniency between individual facilities, where if one
facility discharges more than their allocation, but others discharge less by the same amount, then
overall compliance is achieved. However, should that association disband, then the limits would
be applied directly to each discharger, and no leniency would be awarded at all. Participation in
the association provides each participant some overall aid while also protecting the basin,but the
dischargers are each considered to have total nitrogen and total phosphorous limits in their permits.
The reclassification of the Enfield WWTP to Grade IV has been maintained.
The following changes were made to the draft permit sent to you on November 10, 2020:
• A notation was made concerning the Electronic Reporting Rule — Phase 2 Extension.
extended the Phase 2 deadline from December 21, 2020, to December 21, 2025, effective
January 4, 2021. The current compliance date has been extended to reflect this change.
• The mailing address specified in Special Condition A. (2.) Chronic Toxicity Permit Limit
(Quarterly)has been updated.
• Based on NPDES guidance regarding the reduction of monitoring frequencies in NPDES
permits for exceptionally performing facilities, monitoring requirements for BOD5,NH3-
N,Total Suspended Solids and Fecal Coliform have been reduced to twice per week [See
A.(1)].
This draft permit maintains the following significant changes identified in the letter sent on
November 10, 2020:
• Per 15A NCAC 08G .0302, the facility class has been changed to Grade IV due to the
nutrient limits in the permit and the rule conditions.

• llIAa D-E
▪rmae •_+0+1 /'� 919.707.9000

• As the facility class has been updated, monitoring frequencies for pH, total residual
chlorine and dissolved oxygen have been revised to reflect a Grade IV facility[See A.(1.)].
• Some of the wording has changed in Special Condition A.(2.), Chronic Toxicity Permit
Limit,please review each paragraph carefully.
• Special Condition A.(6.)has been modified to include the specific three years in which the
Effluent Pollutant Scan shall be performed(2022,2023,and 2024). In addition, at the end
of the Special Condition, 2nd species Toxicity Testing Requirements for municipal permit
renewals per Federal Regulations [40 CFR 122.21(j)(5)] have been added.
• A notation was made concerning the Electronic Reporting Rule — NPDES Electronic
Reporting Rule—Phase 2 Extension. EPA extended the Phase 2 deadline to December 21,
2025. The current compliance date, effective January 4, 2021, was extended as a fmal
regulation change published in the November 2,2020 Federal Register.
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[ See A.(1.)].
The NPDES standard conditions(Parts II,III,and IV)that are a part of the permit are not included
in this draft document (cover, map, and Part I). The conditions are the same as in your current
permit except that agency and division names have been updated.The latest version is available at
https://bit.ly/3k5NFaL and can be viewed online or downloaded as a PDF file.
Concurrent with this notification the Division is publishing a notice in a newspaper having
circulation in the general Halifax County area, soliciting public comments on this draft permit.
Please provide any written comments you may have to the following: NCDEQ/DWR,NPDES
Permitting Branch, 1617 Mail Service Center, Raleigh,NC 27699-1617 no later than 30 days
after receipt of this draft permit.
Following the 30-day public comment period,the Division will review all pertinent comments
and take appropriate action prior to issuing a fmal permit. If you have questions concerning this
draft permit,please contact me at(919) 707-3609 or by email at [e-mail].
