This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the US Environmental Protection Agency dated October 15, 2007 (or as subsequently amended). Please take notice that this certificate of coverage is not transferable except after notice to the Division of Energy, Mineral, and Land Resources. The Division may require modification or revocation and reissuance of the certificate of coverage (COC). Please be advised that EPA Region 4 staff who performed a Compliance Sampling Inspection (CSI) at the end of March 2015 and follow-up sampling in June 2015 at other industrial mineral mines in North Carolina raised concerns about metals levels in the discharges. The Stormwater Permitting Program identified mines like this one that have similar activities. During the term of this General Permit, this site may be evaluated further for an alternative permitting action, such as applying to the Division of Water Resources (DWR) for an individual NPDES discharge permit (or modification of its existing wastewater individual permit) prior to the expiration of this General Permit in 2020. This permit does not affect the legal requirements to obtain other permits which may be required by the Division of Energy, Mineral, and Land Resources, or permits required by the Division of Water Resources (DWR), Coastal Area Management Act, or any other federal or local governmental permit that may be required. If the conditions as stipulated in the COC are unacceptable to you, you may apply sooner for an individual NPDES discharge permit.

Davis, P.E., CPM Director, Division of Energy, Mineral and Land Resources By the Authority of the Environmental Management Commission http:/Iportal.ncdenr.org/web/Ir/2015-erenewa1 11 /19/2015 North Carolina Department of Environmental Quality Technical Bulletin for N.C. General NPDES Permit NCG020000 (Mining Environmental Activities) Division of Energy, Mineral, and Land Resources Quality Technical Bulletin for NCG020000 (Mining) Last Revised 101812015 What activities are covered by this general permit? NCG020000 coverage authorizes: • Stormwater discharges associated with mining and quarrying of non-metallic minerals (except fuels), mine excavation, processing, and vehicle maintenance activities (VMA) at mine sites. • Wastewater discharges (dewatering, process wastewater, wastewater recycle system overflows). • Operation of wastewater treatment systems (Authorization to Construct no longer required). NCG020000 coverage is NOT APPLICABLE to: • Borrow Pits covered by the NC DOT statewide stormwater permit. • Peat mining, coal mining, metal mining, or oil & gas extraction operations. • Wastewater not specifically identified by the general permit. What are key stormwater requirements? NCG020000 requires periodic discharge monitoring and a Stormwater Pollution Prevention Plan (SPPP): • Develop and implement an SPPP, and update it at least annually. • Inspect Stormwater Best Management Practices (BMPs) once every seven (7) calendar days. • Semi-annual analytical monitoring and qualitative (visual) monitoring. • Report stormwater monitoring data once a year by March 1 st to DEQ Central Office. • Report benchmark exceedances or Tier 2 monitoring to the DEMLR Regional Office within 30 days. • Respond to benchmark exceedances according to Tier response requirements. What are key wastewater requirements? NCG020000 stipulates wastewater treatment facility operational requirements and periodic discharge monitoring: • Notify DEQ if facility fails to perform satisfactorily or creates nuisance conditions. • Only DEQ-evaluated flocculants may be used, if administered according to maximum application doses. • Quarterly analytical monitoring for first year, or until four consecutive samples comply with all limits (then semi-annual monitoring allowed). Quarterly monitoring schedule resumes upon any limit violation. • Settleable solids (SS) monitoring applies to discharges to HQW, ORW, SA, SB, PNA, or Tr designated waters. • Total Suspended Solids (TSS) limits specific to industrial sand mines, and to any mine discharging to HQW. • Report wastewater effluent monitoring data once a year (by March 1 st) to DEQ Central Office. • Report effluent limitation violations to the DEMLR Regional Office within 30 days. • Effluent turbidity levels above the water quality standard prompt upstream and downstream monitoring. What has changed from the previous permit? Some changes specific to Stormwater: • Reduced BMP inspections (weekly) for active mines; additional allowances for inactive mines that qualify for "dormant status." • Changes to SPPP Annual Update. • "Measureable storm event" (any size that results in a discharge) replaces "Representative" event. • New benchmarks and Tiers specific to turbidity. • Total Flow and event duration no longer required. • pH removed from VMA monitoring. Some changes specific to Wastewater: • May drop to semi-annual WW monitoring after four quarterly samples that comply with all limitations. • Turbidity instream monitoring is required if effluent levels above the water quality standard. • SS monitoring for sensitive waters only (HQW, etc.) . TSS limits apply to industrial sand mines and HQWs. Changes from the last permit are detailed in the "Response to Comments and Summary of Changes" Document for the 2015 NCG02 GP on our website. PACE TECHNICAL BULLETIN FOR N.C. GENERAL NPOES PERMIT NCG020000 (MINING ACTIVITIES) Frequently Asked Questions What if my mine is inactive? The permit makes allowances for Inactive mines that have sus- pended all industrial activities and that certify to DEMLR that the site has been stabilized. If approved for "dormant status," these operations qualify for re- duced 8MP inspections and may be exempted from outfall moni- toring by the Regional Engineer. Do I have to monitor all outfalls? Yes. However, you may request Representative Outfall Status f ROS). If approved, ROS allows monitoring at fewer outfalls. To request ROS, submit an ROS Re- quest Form to the DEMLR Region- al Office. The form is available on our website (below). Also, the Regional Office may exempt mines with "dormant sta- tus" from analytical and/or quali- tative monitoring. What if I sell my business, or the name changes? You are required to notify DEMLR of those changes in writing, and continuation of permit coverage is subject to the Director's ap- proval. Please submit the Name/ Ownership Change form located on our Program website. What do I do when my permit expires? Permitees are not required to sub- mit an application for renewal un- less directed by the Division. The permittee should continue to abide by this general permit if it expires and renewed coverage has not yet been issued. What is wastewater, and what is stormwater at a mine site? Any water contacting an actively mined area, water used to pro- cess mined materials, and mine dewatering water are all consid- ered "wastewater." For some mines, "mine dewatering" also means wet pit overflows, and not just pumped -out water. Any stormwater that commingles with these waters is "wastewater." "stormwater" includes runoff from areas related to mining, pro- cessing, or raw material storage areas, such as haul roads or pro- cessing plant areas at the mine. Sometimes the answer is not clear because of how broad the defini- tions are. For example, N.C. con- siders runoff from areas that cori- tain overburden only (no mined or processed m(iterial), and that does not commingle with wastewater (including runoff from the mine), to be stormwater. If you are unsure about discharges, please contact the DEMLR Re- gional Office for assistance. Does a certified lab need to analyze my samples? Monitoring under NPDES permits must be conducted in accord- ance with test procedures ap- proved in federal regulations in 40 CFR § 136. All labs certified by LAST REV. 101811 S North Carolina perform analysis in accordance with those proce- dures. While N.C. certification re- quirements do not apply to testing stormwater-only discharges, data gathered under an NPDES permit must still conform to federal re- quirements. Using a North Caroli- no certified lab is one way to en- sure compliance. A list of certified labs is available from: http:// . portal.ncdenr.org/web/wq/lab/ cert/ What if I pull samples for my analytical monitoring, and I'm unable to get a sample or valid results for a parameter? If this happens, please sample for the missing parameter during the next measureable storm event or wastewater discharge. If I sample my discharge, do have to do visual monitoring at the same time? You may, but it is not necessary under NCG02. Some other gen- eral permits require it, however. What if there is no flow for a period between two samples that exceed a benchmark? Are those consecutive exceedances? Yes. This scenario still puts you in Tier 2. The new permit is more clear about how the Tier 2 trigger omits periods of no discharge.

(See information below.) ❑ Yes ❑ No Please verify whether Qualitative Monitoring must be performed during a "representative storm event" or "measureable storm event" (requirements vary, depending on the permit). Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be performed during a "representative storm event" or during a "measureable storm event." However, some permits do not have this requirement. Please refer to these. definitions, if applicable. A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than 0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no precipitation. A "measurable storm event" is a storm event that results in an actual discharge from the permitted site outfall. The previous measurable storm event must have'been atleast 72 hours prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter interval is representative for local storm events during the sampling period, and the permittee obtains approval from the local DWQ Regional Office.
