Permit Renewal NC0034754
Dear Mr. Coco:
Please find enclosed the renewal application for NPDES permit NC0034754 located at 6519 CommScope
Road, Catawba, NC 28609. There have been no changes at the WWTP since the last permit issuance and
the treatment facility continues to handle 100% domestic wastewater. Two items should be noted on EPA
Form 2E. The facility indicated that chlorine is used in Section 4.5. The facility does not currently add
chlorine to the water that is discharged and therefore does not sample for TRC. However, the permittee
requests this parameter remain in the permit to maintain flexibility to use chlorine if needed. In addition,
the maximum and average values presented in Sections 4.2 and 4.4 are an overestimation of the facility's
sampling data. Lab results which were presented with less than symbols have been replaced with the lab
Iess than value. For example, a sample result of < 2.7 mg/1 has been changed to 2.7 mg/1 to calculate
maximum and average values. As shown in Attachment C, Table 1 demonstrates the actual sampled
data and Table 2 demonstrates the overestimated data.
Please feel free to contact me at 828-241-6037 with any questions.
Sincerely,
Laura R. Moody
