Subject: SIU Permit Renewal. Permit#0001 Century Hosiery
Dear Mr. Hassan;
I am enclosing Century Hosiery, Inc. Industrial Permit. This is a scheduled renewal.
In this permit renewal we decreased the allocation of Copper and Zinc. These changes were
made due to the industry changing their dyes used and reduction in business. All other
parameters including Flow remain the same.
If you require further information, please contact Troy B. Branch at 336/859-4460
[e-mail]. Thank you for your assistance in this matter.
Sincerely,

RATIONALE#1:
Review of IU Monitoring Data, with no Over Allocation situation:
The following pollutants were assigned numerical limits in this IUP based on a
review of monitoring data for the permittee to determine what ranges of
concentrations are currently being discharged. To account for sample variability a
factor was applied to the monitoring data to determine the permit limit. Permit limits
assigned by the Local IUP Control Authority can not results in an Over Allocation
situation for any pollutants.

Over Allocation Prevention, with IU pollutant reduction:
The following pollutants were assigned numerical limits in this IUP based on
allocating the Maximum Allowable Industrial Loading(MAIL) determined with the
Headworks Analysis (HWA) among all Industrial Users. The total loading of each
pollutant from all permitted discharges does not exceed the MAIL. These limits do
not result on over allocations.

RATIONALE#3b:
Interim Limits for IU pollutant reduction:
The following pollutants were assigned interim numerical limits in this IUP to allow
time for the industry to come compliance with final limits that will not in over
