This permit shall become effective Month Day, 2023. This permit and authorization to discharge shall expire at midnight on Month day, 2028. Signed this day Month Day, 2023. DRAFT Richard E. Rogers, Jr., Director Division of Water Resources By Authority of the Environmental Management Commission Permit NCO049905 SUPPLEMENT TO PERMIT COVER SHEET All previous NPDES Permits issued to this facility, whether for operation or discharge are hereby revoked, and as of this issuance, any previously issued permit bearing this number is no longer effective. Therefore, the exclusive authority to operate and discharge from this facility arises under the permit conditions, requirements, terms, and provisions included herein. Associated Asphalt Salisbury, LLC is hereby authorized to: 1. Continue to operate an existing Wastewater Treatment Facility consisting of the following: ➢ A 0.5 MGD retention pond with effluent discharge into a dry ditch via Outfall 001, and ➢ A stormwater containment berm (around tank #5) with a discharge into a dry ditch via Outfall 002. 2. The facility is located at 1825 Jake Alexander Boulevard, Salisbury, Rowan County. 3. Discharge of boiler blowdown, water softener blowdown and stormwater (via outfall 001) and stormwater from stormwater containment berm (via outfall 002) into an unnamed tributary to Grants Creek, classified C waters in the Yadkin -Pee Dee River Basin, at the location specified on the attached map. Page 2 of 8 Permit NCO049905 PART I A. (1) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS [15A NCAC 02B .0400 et seq., 02B .0500 et seq.] Grade I Physical/Chemical Water Pollution Control System [I 5A NCAC 08G .0306] Beginning on the effective date of this permit and lasting until permit expiration, the Permittee is authorized to discharge boiler blowdown, water softener blowdown and stormwater from Outfall 001 and stormwater from Outfall 002. Such discharges shall be limited and monitored' by the Permittee as specified below: Effluent Characteristics Parameter Code Discharge Limitations Monitoring Requirements Monthly Average Daily Maximum Measurement Frequency Sample Type Sample Location FlowZ 50050 Quarterly Estimated Effluent Total Suspended Solids C0530 45.0 m L 67.5 mg/L Quarterly Grab Effluent Total Residual Chlorine 3 50060 50 ,,/L Quarterly Grab Effluent Oil and Grease' 00556 45.0 m 67.5 mg/L Quarterly Grab Effluent Turbidity5 50 NTU Quarterly Grab Effluent Temperature' °C 00010 Quarterly Grab Effluent H 00400 1 Between 6.0 and 9.0 standard units i Quarterly Grab Effluent Footnotes: 1. Submit discharge monitoring reports electronically using the NC DWR's eDMR application system [See section A. (2.)]. 2. Flow shall be monitored with each discharge event. During periods of no flow, the Permittee shall submit a signed, monthly Discharge Monitoring Report (DMR) indicating "No discharge." Flow may be monitored using any one of four methods: a) Measure flow continuously b) Calculate flow (see Rational Equation below) based on total rainfall per unit area draining to the outfall; exclude built -upon areas (best method for facilities with large runoff -collection ponds) The Rational Equation: Q = KuC1A, where: Q = flow (peak flow rate (cfs or m3/sec) Ku = units conversation factor =1.008 for U.S. standard units (usually ignored because it is so close to 1), or 0.278 for SI units C = dimensionless runoff coefficient for the watershed, loosely defined as the ratio of runoff to rainfall I = intensity of rainfall taken from the intensity -duration -frequency curves for the specified design return period at the time of concentration, tc (in/h or mm/h). tc = time of concentration (time after the beginning of rainfall excess when all portions of the drainage basin are contributing simultaneously to flow at the outlet). A = area of tributary watershed (acres or km') The rational equation is used to calculate the runoff from a region, given: i) the runoff coefficient which accounts for infiltration and other potential losses in the region ii) the rainfall intensity to the region iii) the time it takes for runoff to travel from the region's upper reaches to its outlet iv) the region's drainage area Page 3 of 8 Permit NCO049905 c) Estimate flow at 20-minute intervals during the entire discharge event d) Report flow based on discharge pump logs 3. Effluent monitoring and limitation only apply if chlorine or a chlorine derivative is added to the waste stream during treatment. The Division shall consider all effluent TRC values reported below 50 µg/L to be in compliance with the permit. However, the Permittee shall continue to record and submit all values reported by a North Carolina certified laboratory (including field certified), even if these values fall below 50 µg/L. 4. Oil and grease samples shall be skimmed from the surface of a quiescent (calm water) zone. 5. The discharge from this facility shall not cause turbidity in the receiving stream to exceed 50 NTU. If the instream turbidity exceeds 50 NTU due to natural background conditions, the discharge cannot cause turbidity to increase in the receiving stream. Therefore, if the effluent measurement exceeds 50 NTU, the Permittee shall sample upstream and downstream turbidity in the receiving waterbody, within 24 hours, to demonstrate the existing turbidity level in the receiving waterbody was not increased. All data shall be reported on the DMRs. (See 15A NCAC 2B .0211 (21)). 6. The temperature of the effluent shall be regulated so as not to cause an increase in the temperature of the receiving stream of more than 2.8°C and in no case cause the ambient water temperature to exceed 32°C. The permittee shall obtain authorization from the Division prior to the use of any chemical additive in the discharge. The permittee shall notify the Director in writing at least ninety (90) days prior to instituting use of any additional additive in the discharge which may be toxic to aquatic life (other than additives previously approved by the Division). Such notification shall include completion of Biocide Worksheet 101 (if applicable), a copy of the MSDS for the additive, and a map indicating the discharge point and receiving stream. There shall be no chromium, zinc, or copper added to the discharge except as pre -approved additives to biocidal compounds. All samples collected should be from a representative discharge event. There shall be no discharge of floating solids or visible foam in other than trace amounts. Page 4 of 8 Permit NCO049905 A. (8) ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.1(b)] Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December 21, 2015. NOTE: This special condition supplements or supersedes the following sections within Part II of this permit (Standard Conditions for NPDES Permits): • Section B. (11.) Signatory Requirements • Section D. (2.) • Section D. (6.) • Section E. (5.) Reporting Records Retention Monitoring Reports 1. Reporting Reauirements (Supersedes Section D. (2.) and Section E. (5.) (a)] The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application. Monitoring results obtained during the previous month(s) shall be summarized for each month and submitted electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring data and submit DMRs electronically using the internet. Until such time that the state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR), permittees will be required to submit all discharge monitoring data to the state electronically using eDMR and will be required to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the computer printed eDMR to the following address: NC DEQ / Division of Water Resources / Water Quality Permitting Section ATTENTION: Central Files 1617 Mail Service Center Raleigh, North Carolina 27699-1617 If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being physically located in an area where less than 10 percent of the households have broadband access, then a temporary waiver from the NPDES electronic reporting requirements may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the mailing address above. See "How to Request a Waiver from Electronic Reporting" section below. Regardless of the submission method, the first DMR is due on the last day of the month following the issuance of the permit or in the case of a new facility, on the last day of the month following the commencement of discharge. Starting on December 21, 2025, the permittee must electronically report the following compliance monitoring data and reports, when applicable: Sewer Overflow/Bypass Event Reports; Pretreatment Program Annual Reports; and Clean Water Act (CWA) Section 316(b) Annual Reports. The permittee may seek an electronic reporting waiver from the Division (see "How to Request a Waiver from Electronic Reporting" section below). Page 5 of 8 Permit NC0049905 2. Electronic Submissions In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time of each electronic submission. The permittee should use the EPA's website resources to identify the initial recipient for the electronic submission. Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity (EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity for receiving electronic NPDES data [see 40 CFR 127.2(b)]. EPA plans to establish a website that will also link to the appropriate electronic reporting tool for each type of electronic submission and for each state. Instructions on how to access and use the appropriate electronic reporting tool will be available as well. Information on EPA's NPDES Electronic Reporting Rule is found at: https://www.federalre ig ster.gov/documents/2015/10/22/2015-24954/national-pollutant-discharge-elimination- system-nodes-electronic-reporting-rule. Electronic submissions must start by the dates listed in the "Reporting Requirements" section above 3. How to Request a Waiver from Electronic Reportinu The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to the Division. Requests for temporary electronic reporting waivers must be submitted in writing to the Division for written approval at least sixty (60) days prior to the date the facility would be required under this permit to begin submitting monitoring data and reports. The duration of a temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data and reports shall be submitted electronically to the Division unless the permittee re -applies for and is granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting waivers are not transferrable. Only permittees with an approved reporting waiver request may submit monitoring data and reports on paper to the Division for the period that the approved reporting waiver request is effective. Information on eDMR and the application for a temporary electronic reporting waiver are found on the following web page: http://deq. nc. gov/about/divisions/water-resources/edm r 4. Sip_natory Requirements (Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)1 All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II, Section B. (I 1.)(a) or by a duly authorized representative of that person as described in Part II, Section B. (I 1.)(b). A person, and not a position, must be delegated signatory authority for eDMR reporting purposes. For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user account and login credentials to access the eDMR system. For more information on North Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit the following web page: http:Hdeg.nc.,pov/about/divisions/water-resources/edmr Certification. Any person submitting an electronic DMR using the state's eDMR system shall make the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION WILL BE ACCEPTED: V certijy, under penalty of law, that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and Page 6 of 8 Permit NCO049905 evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fines and imprisonment for knowing violations. " 5. Records Retention [Supplements Section D. (6.)l The permittee shall retain records of all Discharge Monitoring Reports, including eDMR submissions.
