HomeMy WebLinkAboutNC0006220_Fact Sheet_20190506FACT SHEET FOR EXPEDITED PERMIT RENEWALS This form must be completed by Permit Writers for all expedited permits which do not require full Fact Sheets. Expedited permits are generally simple 100% domestics (e.g., schools, mobile home parks, etc) that can be administratively renewed with minor changes, but can include facilities with more complex issues (Special Conditions, 303(d) listed water, toxicity testing, instream monitoring, compliance concerns). Basic Information for Expedited Permit Renewals Permit Writer / Date Sydney Carpenter 11/8/18 Permit Number NC0006220 Facility Name / Facility Class City of Kanna olis WTP / PC-1 Basin Name / Sub -basin number Yadkin -Pee Dee / 03-07-12 Receiving Stream / HUC UT to Irish Buffalo Creek (locally known as Bakers Branch)/ 0304010502 Stream Classification / Stream Segment C / Index: 13-17-9- 2 Does permit need Daily Max NH3 limits? No Does permit need TRC limits/language? Already included. Does permit have toxicity testing? IWC if so. Yes; IWC % is 90 Does permit have Special Conditions? Yes — Compliance Schedule for new Zinc limits Does permit have instream monitoring? Yes — Hardness Total as CaCO3 sampling upstream Is the stream impaired (on 303(d) list)? If yes, for what arameter(s)? Yes — Copper (7 µg/l, AL, FW) Any obvious compliance concerns? No, compliance record is good. Any permit mods since lastpermit? No New expiration date 10/31/2023 Facility Overview: The City of Kannapolis WTP operates a conventional treatment WTP designed for a potable flowrate of 15 MGD and a continuous wastewater (backwash) discharge of 0.250 MGD. The maximum, monthly average wastewater discharge between Sept 2015 and Sept 2018 was approximately 0.3744 MGD. Compliance History: • Two violations during a 2009 Compliance Inspection regarding proper certification to perform pH measurements and the procedure not followed for pH and TRC. • 100% Tox test passing rate in past 3 years. RPA: The maximum monthly average flow between Sept 2015 and Sept 2018 was approximately 0.3744 MGD. • Copper - no reasonable potential to exceed water quality standards; predicted max > 50% of allowable concentration; monitoring kept at quarterly, and receiving stream is on the 2016 303(d) impaired waters list for copper. • Fluoride - no reasonable potential to exceed water quality standards; predicted max < 50% of allowable concentration; monitoring kept at quarterly as facility indicated fluoride has the potential to be discharged. • Zinc - reasonable potential to exceed water quality standards; applying monthly monitoring with limits. NCG59 General Permit Eligibility (for Conventional & Greensand WTPs): • They've passed the all TOX tests within the last 3 years (July 2015-July 2018) — eligible • Zinc limits required based on most recent RPA — ineligible • Conclusion: Ineligible for NCG59 General Permit. Changes from previous permit to draft: • Added regulatory citations • Updated map • Updated eDMR footnote in A(1) and language in A(4) • Updated Supplement to Cover Sheet #1 information to include facility address and #2 to include stream index and HUC. • Added facility grade in A(1) • Updated components list to add Residuals Lagoon • Removed former footnote #2 stating "Parameters should be monitored in conjunction with toxicity test.", as this is no longer required per 2009 Changes to WTP Strategy Memo • Removed Iron parameter in A(1) Effluent table. Application states Iron sulfate does not have the potential to be discharged. As per "Assistance with BPJ on WTP renewals" 2012 Memo, Iron does not have a recommend limit and was monitoring only in previous permit. All reported values in previous 3 years are < 1 mg/L. • Added Hardness to A(1) Effluent table to monitor in conjunction with hardness dependent metals already being monitored (copper, zinc), as per "Implementation of Instream Dissolved Metals Standards" 2016 Memo. Sampling in effluent and upstream. • Added Zinc limits and monthly monitoring to A(1) Effluent table, as RPA showed a reasonable potential to exceed WQS. • Added footnote #3 for new compliance schedule. • Added Section A(3) compliance schedule for new zinc limits and monitoring. • Updated Turbidity monitoring frequency to monthly, as per "Assistance with BPJ on WTP renewals" 2012 Memo. Changes from draft to final: • No changes made. Comments received on draft permit: • No comments received.

Page 3 of 3 Version 6/2017 R U City of Kannapolis WTP Solids Handling Plan Settled solids and Alum residuals are removed from our Sedimentation basins by way of a Trac- Vac system. These solids are pumped to a Residuals Lagoon. Any decant water from the lagoon is sent to the Rocky River WWTP, Cabarrus County (Local Pretreatment No. 203). Solids/Alum Residuals are generally removed from the lagoon and disposed of, per regulations, when necessary. Budgeting has been approved to contract out the removal of solids from the lagoon in 2019. These solids will be removed in compliance with state and local regulations. Backwash water is sent to an Equalization basin and then pumped to a circular Clarifier, which settles out the solids. A scraper arm pushes solids into a trough and then sends them to the sludge pumping station where they are pumped to the Solids Lagoon. The decant water is then de - chlorinated and sent to Bakers Branch of Irish Buffalo Creek.. Flow measurement is calibrated quarterly by Fortech, Inc, Charlotte, NC.

Re: [EXTERNAL] 7Q10 and 30Q2 Mr. Faulkner, In response to your inquiry about the 7Q10 and 30Q2 low -flow characteristics for a "drainage ditch" to an unnamed tributary of Irish Buffalo Creek adjacent to Secondary Road 1109 (Pump Station Road) near Kannapolis in southern Rowan County, the following information is provided: A check of the low -flow files here at the USGS South Atlantic Water Science Center (Raleigh office) does not indicate a previous low -flow determination for the point of interest, as identified by the lat/long coordinates (35.509886,-80.645548) confirmed via your email dated January 28, 2019. No USGS discharge records are likewise known to exist for the point of interest. In the absence of site -specific discharge records sufficient for a low -flow analysis, estimates of low -flow characteristics at ungaged locations are determined by assessing a range in the low -flow yields (expressed as flow per square mile drainage area, of cfsm) at nearby sites where estimates have been determined. For streams in southern Rowan County, low -flow characteristics published by the USGS are provided in the following reports: (1) The first is a statewide report completed in the early 1990's. It is USGS Water -Supply Paper 2403, "Low -flow characteristics of streams in North Carolina" (Giese and Mason, 1993). An online version of the report is available at http://pubs.usgs.gov/wsp/2403/report.pdf. The report provides the low -flow characteristics (based on data through 1988) via regional relations and at -site values for sites with drainage basins between 1 and 400 sgmi and not considered or known to be affected by regulation and/or diversions. (2) The second is a basin -wide report for the Rocky River basin published in 2003. It is USGS Water - Resources Investigations Report 03-4147, "Low -Flow Characteristics and Profiles for the Rocky River in the Yadkin -Pee Dee River Basin, North Carolina, through 2002" (Weaver and Fine, 2003). An online version of the report is available through http://pubs.usgs.gov/wri/wri034147/. The report provides the low -flow characteristics (based on data through 2002) for continuous -record gaging stations and partial - record sites within the Rocky River basin. The report also provides low -flow discharge profiles (7Q10, 30Q2, winter 7Q10, and 7Q2) for the Rocky River from its headwaters in Mecklenburg County to its mouth. (3) The third is a statewide report recently published in March 2015. It is USGS Scientific Investigations Report 2015-5001, "Low -flow characteristics and flow -duration statistics for selectedUSGS continuous - record streamgaging stations in North Carolina through 2012" (Weaver, 2015). The report is available online at http://pubs.usgs.gov/sir/2015/5001/. The report provides updated low -flow characteristics and flow -duration statistics for 266 active (as of 2012 water year) and discontinued streamgages across the state where a minimum of 10 climatic years discharge records were available for flow analyses. A basin delineation completed using the online USGS StreamStats application (https://water.usgs.gov/osw/streamstats/) indicates the drainage area for the point of interest (35.50990 -80.64552 NAD83) is about 0.03 sgmi. Consideration of the very small drainage area upstream from the point of interest results in a conclusion that the 7Q10 discharge for the point of interest is zero flow. Inspection of 30Q2 low -flow yields in the second report for nearby sites where low -flow characteristics were published suggests the 30Q2 discharge for the point of interest is less than 0.01 cfs, if not zero flow. Please understand the information provided in this message is based on a preliminary assessment and considered provisional, subject to revision pending further analyses. Again, I regret any inconvenience for you caused by the delay of this response (due to federal government shutdown December 22 through January 25), but am appreciative of your understanding. Hope this information is helpful. Thank you. Curtis Weaver J.
