Subject: Final NPDES Permit
Permit NCO089109
Befesa Zinc Metal, LLC
Rutherford County
Facility Class II
The Division of Water Resources is forwarding herewith the Final Permit for Befesa Zinc Metal, LLC.
This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and
the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection
Agency dated October 15, 2007 (or as subsequently amended).
The Final Permit contains the following significant changes from your Draft Permit:
• The Division added the requirement to report sulfide and surfactant concentrations during
the next permit renewal.
• The monitoring for hardness was added to the permit to facilitate implementation of the
dissolved metal standards.
• The continuous monitoring for pH and conductivity was added to the permit to develop a
better understanding of the periodic toxicity test failures.
The Final Permit maintains the following significant changes contained in the Draft Permit:
• The quarterly monitoring for Total Selenium and Total Silver was added to the permit based
on the results of the Reasonable Potential Analysis.
• The monitoring for Total Nickel and Total Lead was reduced to quarterly based on the results
of the Reasonable Potential Analysis.
• The monitoring for Total Tin, Total Antimony, Total Aluminum, and Total Fluoride was
eliminated from the permit based on the results of the Reasonable Potential Analysis.
• The monitoring for Total Iron was eliminated from the permit because Iron standard for
surface waters was removed by the state of North Carolina.
• The monitoring for Total Cobalt was eliminated from the permit based on the review of the
effluent data.
• The intermediate Cadmium limits and compliance schedule was removed from the permit
since the facility already achieved compliance with the final Cadmium limits.
