Subject: Review of NPDES Permit DRAFT
Renewal of NPDES NC0007609 for
Diamond Shoal Seafood,Inc.,WPCS Class PCNC
4146 Orchard Creek Road,
Oriental,North Carolina
Pamlico County
Mr.Fulcher:
In response to your request to renew the subject NPDES permit, received September 26,2023,the
Division of Water Resources (DWR or the Division)hereby transmits this draft permit for your
review and comment. Please review this document carefully to assure your understanding of the
permit limits and monitoring conditions, and to correct errors,if any.
Concurrent with this notification,the Division will solicit public comment on this draft by
publishing a notice in newspapers having circulation in the general Pamlico County area, as
required by the NPDES Program. Please provide your written comments, if any, to me via email
[[e-mail]] or write to my attention care of NCDEQ/DWR/NPDES Program no
later than May 31,2024, approximately 30 days after receiving this letter. Your written comments
are welcome,but they are not mandatory.
The Division notes from your renewal application that Diamond Shoal Seafood, Inc(herein
Diamond of the Permittee)has made no significant alterations to site activities since last renewal.
However, we have made updates to your permit texts and format. We note that you have not
estimated speciated production that may infer daily maximums (DM)or monthly averages (MA).
DWR needs these to calculate permit limits under 40 CFR. We have therefore calculated renewal
permit limits based on your database reported during the previous permit cycle. In addition, DWR
has replaced federal technology-based effluent limits(TBELs)with North Carolina water-quality
based effluent limits(WQBELs)for seafood process-contact discharges (see Fact Sheet). We have
thereby made some significant permit limit changes for renewal:
OUTFALL 001 —NON-Process-Contact Wastewater—O&G limits lowered from 15 mg/L
Monthly Average(MA) and 20 mg/L Daily Max (DM) to 7.5 mg/L MA/ 10 mg/L DM,
consistent with process-contact outfalls.
OUTFALLS 002, 003, and 004 --Upon review of 40 CFR 408.122, the Division concludes that
calculated federal TBEL permit limits in mass are less protective of local surface water-quality.
Consistent with permitting statewide, it is DWR's best professional judgment(BPJ)that NC limits
better protect surface waters. Therefore,DWR has applied WQBEL limits in concentrations(mg/L)to all
production-based outfalls(see permit tables, Sections A. (2.),A. (3.), and A.(4.).
