Permit Application Correction-Page 18
Dear Julie,
In reviewing the recently submitted NPDES Permit Renewal Application for the
North Buffalo Water Reclamation Facility (NPDES Permit #NC0024 325), we
discovered a clerical error on Pare 18 Section F.2. The number of CIUs should
have been reported as 3 rather than 4. North Buffalo has a total of 4 Significant
Industrial Users. 3 of which are CIUs.
Enclosed please find 2 copies of the amended page 18, with the correction date
noted.
If you require any additional information or have any questions, please feel free to
contact me at 336-433-7229 or by email at [e-mail].
Sincerely.

Effluent Testing: 1.0 mgd and Pretreatment Works. If the treatment works has a design flow greater than or equal to 1.0 mgd or it has(or is required
to have)a pretreatment program,or is otherwise required by the permitting authority to provide the data,then provide effluent testing data for the following
pollutants. Provide the indicated effluent testing information and any other information required by the permitting authority for each outfall through which
effluent is discharged. Do not include information on combined sewer overflows in this section. All information reported must be based on data collected
through analyses conducted using 40 CFR Part 136 methods. In addition,these data must comply with QA/QC requirements of 40 CFR Part 136 and
other appropriate QA/QC requirements for standard methods for analytes not addressed by 40 CFR Part 136. Indicate in the blank rows provided below
any data you may have on pollutants not specifically listed in this form. At a minimum,effluent testing data must be based on at least three pollutant
scans and must be no more than four and one-half years old.
Outfall number: 001 (1/1/13 to 9/30/15) (Complete once for each outfall discharging effluent to waters of the United States.)

SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1)POTWs with a design flow rate greater than or equal to 1.0 mgd;2)POTWs with a pretreatment program(or those that are
required to have one under 40 CFR Part 403);or 3)POTWs required by the permitting authority to submit data for these parameters.
• At a minimum,these results must include quarterly testing for a 12-month period within the past 1 year using multiple species(minimum of two
species),or the results from four tests performed at least annually in the four and one-half years prior to the application,provided the results
show no appreciable toxicity,and testing for acute and/or chronic toxicity,depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition,this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition,submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity,provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation,if one was conducted.
• If you have already submitted any of the information requested in Part E,you need not submit it again. Rather,provide the information
requested in question E.4 for previously submitted information. If EPA methods were not used,report the reasons for using alternate methods.
If test summaries are available that contain all of the information requested below,they may be submitted in place of Part E.
