Becker, President c/o Amanda Berger Aqua North Carolina, Inc. 202 Mackenan Court Cary, North Carolina 27511 Subject: Request for Additional Information Renewal Application Stonington Subdivision - Well #1 NPDES permit NC0088501 Forsyth County Dear Mr. Becker: The Division has reviewed your application, received on October 5, 2018, for renewal of NPDES permit NC0088501. To enable us complete our review in accordance with N.C.G.S. 143-215.1 and 15A NCAC 2H.0105, please provide additional or revised information to address the following comments: 1. Please provide five (5) days of Total Hardness (CaCO3 or (Ca + Mg)) data for the effluent at Outfall 001. 2. Please note the attached data reporting errors form May2014 to October 2018 for permit NC0088501 and others. Many errors involved reporting the incorrect unit of measure (UoM) such as mg/L verses µg/L. Another error noted was reporting a value of zero (0) for “no detection” for Total Residual Chorine (TRC) results instead of reporting the method practical quantitation limit (PQL) such as < 20 µg/L. If these are indeed errors, please correct DMRs accordingly. Please note you may want to review and correct DMRs since October 2018 as well. The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the NC Environmental Management Committee (EMC) on November 13, 2014. The US EPA subsequently approved the WQS revisions on April 6, 2016 with some exceptions. The NC Division of Water Resources is required to implement the new dissolved metal standards in all permits public noticed after April 6, 2016. The new standards for most metals include acute standards. Furthermore, the freshwater standards for several metals are expressed as the dissolved form of the metals, and seven metals have hardness- dependent equations. As a result, the Division will need site-specific effluent hardness data and instream hardness data, upstream of the discharge, for each facility monitoring these metals in order to calculate permit limitations. The metal of concern for this permit renewal is Zinc. To evaluate dissolved Zinc, a Reasonable Potential Analysis (RPA) was conducted using data from DMRs (May2014–Oct2018) [see attached RPA spreadsheets for Outfall 001]. Results indicated a reasonable potential to exceed the new dissolved metals standard for Zinc. Consequently, the following Mr. Becker May 6, 2019 Page 2 of 2 daily maximum limits (acute standard) and monthly average limits (in this case the acute standard) for Total Zinc could be applied for this permit renewal: Parameter Outfall Monthly Average Limit Daily Maximum Limit Zinc 001 125.7 µg/L 125.7 µg/L Please note that the hardness-dependent water quality standard for zinc typically results in a more stringent permit limit for the acute total allowable metal verses the chronic value. In this situation, we use the acute total allowable metal concentration (permit limit) as the limitation for both the Daily Maximum and the Monthly Average. To calculate these limits a default hardness of 25 mg/L was entered for both the effluent and upstream values. Since this facility discharges under zero flow conditions a value of 0 was entered for all stream flow data. Please note that under zero flow conditions the default value of 25 mg/L will be using for the upstream Total Hardness. Additionally, the maximum monthly average flow of 0.0009 MGD from November 2015 to October 2018 (3 years) data was used as the effluent flow. For a summary of this information, please see the attached “Dissolved to Total Metal Calculator”. If no response is received within 60 calendar days [per 15A NCAC 2H.0107(b)], the permit will be renewed without the benefit of the requested additional information. Therefore, a default effluent hardness of 25 mg/L will be used to calculate effluent limits for Zinc as indicated above.
