Grade IV Biological WPCS
SIC Code 4952
Dear Mr. Smithwick,Jr.:
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.There are several changes from the existing permit,including the following:
• 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)].
• Based on Mercury TMDL evaluation showing all reported mercury values at levels< 1
ng/L, Special Condition A.(9.)Mercury Minimization Plan has been removed from the
permit.
• The Division is implementing dissolved metals standards in all permits,per the 2016
revisions to State water quality standards.As such,the NPDES Permitting Unit will need
site-specific effluent hardness data and instream hardness data,upstream of the discharge,for
each facility monitoring these metals in order to calculate permit limitations. Effluent
hardness and instream hardness sampling,upstream of the discharge,have been added to the
permit at a monitoring frequency of quarterly[See A.(1.)].
• As instream sampling requirements have been moved to Section A.(1.), Special Condition
A.(2.)Instream Monitoring Requirements has been removed from the permit.
• Some of the wording has changed in Special Condition A. (5.), 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.
• Federal regulations require electronic submittal of all discharge monitoring reports
(DMRs)and program reports.The requirement to continue reporting discharge monitoring data
electronically using the NC DWR's Electronic Discharge Monitoring Report(eDMR) Internet
application has been added to your NPDES permit[See Special Condition A. (7.)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[ See A. (1.)].
• Regulatory citations have been added to the permit.
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

reporting waivers are not transferrable. Only permittees with an approved reporting waiver
request may submit monitoring data and reports on paper to the Division for the period that the
approved reporting waiver request is effective.
