Permitting Section
Please see attached NPDES Permit Renewal request and application for NPDES Permit NC0031879, Corpening Creek
WWTP in McDowell County.
Of note the City respectfully requests a renewal of our tiered permit with first level tier of 2.5 MGD and second level
tier of 3.0 MGD.
This would also allow Corpening Creek WWTP to continue to plan and allocate resources to maximize operations,
monitoring, and water quality protection. We are in hopes of having our monitoring requirements remain at 3 times
per week due to our average flow being less than 1.2MGD. And as the tier requirements are increased so would our
testing back to the level as the permit requires at 3.0 MGD. Also we would like to request our ammonia limits be
established at a level that is compatible to the surrounding WWTP facilities in our area (The permits for the
surrounding facilities reflect the weekly average 11 to 35mg/I and the monthly average 4 to 16mg/I) our DMRS show
that we have never had a toxicity problem at our facility, The toxicity information will be submitted upon completion
of the laboratory, Should you have any questions or need additional information please contact me at 828-652-8843
or [e-mail].
Thank llqu , Larry rver WWTP Superintendent

PARTS 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. AU 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.
If no biomonitoring data is required, do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to complete.
