PO Box 2151 Smithfield, NC 27577 Subject: General Permit No, NCG020000 McBryde Farm Pit COC NCG020936 Johnston County Dear Mr. Eason: In accordance with your application for a discharge permit received on August 08, 2018, we are forwarding herewith the subject certificate of coverage to discharge under the subject state - NPDES general permit. 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. Per the requirements of the Neuse Riparian Buffer Rule, all stormwater drainage to stream buffers, from portions of this site that have been constructed after July 22, 1997, must be discharged through a correctly designed level spreader or another device that meets diffuse flow requirements per 15A NCAC 2B .0233. Diffuse flow requirements are described in Chapter C-9 of the North Carolina Stormwater BM P Manual, available at: http://Dortal.ncdenr,g/web/lr/bmp-manual. This general permit allows the discharge of stormwater. If separate point -source discharges of stormwater occur (i.e., stormwater notcombined with mine dewatering water), you will be required to adhere to the conditions in this permit for stormwater discharges. This permit does not affect the legal requirements to obtain other permits which may be required by the Division of Energy, Mining, and Land Resources, or permits required by the Division of Water Resources, Coastal Area Management Act, or any other federal or local governmental permit that may be required. If you have any questions concerning this permit, please contact Richard Riddle at telephone number (919) 707-3648. Sincerely, for illiam E.

(see attachment) The dewatering basin will receive flow from the pumps (77,400 gpd or 0.12 cfs, see attached calculations) as well as surface water (4.85 ac or Q25 = 8.74efs, see attached calculations) A 40' X 80' X 3' dewatering basin is proposed. The surface area and volume are greater than that required for a dewatering basin sized for these proposed pumps (required 20' X 40' X3' see attached "dewatering basin design" worksheet) The attached calculations show that this dewatering basin will also act as a "non -discharge stormwater control", because the volume and surface area is large enough for the Q25yr storm event plus flow from the dewatering pumps and the time to drain is less than 5 days. Attached are specifications and information the client provided pertaining to the dewatering pump that will be used at the site. The client also provided hours of operation. See below 7AM — 5PM = 10hrs @ 80 gpm = 48,000 gallons 5PM -- 7AM = 141irs @ 35 gpm = 29,400 gallons 77,400 gallons per day or 0. 12cfs Permit No. NCG020000 and process areas. Analytical monitoring for stormwater discharges shall be performed for parameters as specified in Tables 1 through 3. All analytical monitoring shall be performed aurine a representanve storm event as aennea petow. Monitoring Exemption Analytical monitoring is not required for any basin or pond designed to contain the 25-year, 24- hour storm (see Part Vll, Definitions) without discharging, and that can regain capacity to hold such an event within five (5) days' time through means other than discharge to surface waters. A basin or pond that meets this provision is considered a non -discharging stormwater control. Table 1.

Grab samples shall he collected within the first 30 minutes of discharge. For sites where multiple outfalls are separated by distances that preclude collection within 30 minutes of each discharge event is not feasible, begin collection procedures within 30 minutes and continue until all outfalls with discharges are sampled. Documentation explaining why it was not possible to take samples within the first 30 minutes must be kept in the SPPP. 3. Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless representative outfall status (ROS) has been granted and documented by the Division of Water Quality. A copy of the letter granting ROS shall be kept on site. 4. Turbidity may be monitored at the Stormwater Discharge Outfall. Alternatively, the permittee may choose to monitor turbidity in the receiving water, directly upstream and downstream of the stormwater discharge outfall(s). 5. For each sampled representative storm event the total precipitation must be recorded. An on -site rain gauge or local rain gauge reading must be recorded. 6. Total flow shall be; (a) measured continuously, or (b) calculated based on the amount of area draining to the outfall, the amount of Impervious area, and the total amount of rainfall, or (c) estimated by the measurement of flow at 20 minute intervals during the rainfall event Total rainfall precipitation and duration of the rainfall event refers to the representative storm event sampled. All analytical monitoring shall be performed during a representative storm event at each stormwater discharge outfall (SDO). The permit allows the permittee to monitor turbidity at the SDO or up- and downstream of the SDO; however, the permittee should consider regular turbidity sampling up- and downstream of the discharge(s) when feasible to ensure compliance with water quality standards.

Smaller areas with slowly permeable soils, steep slopes, and sparse vegetation should be assigned highest C values. Source: American Society of Civil Engineers The overland flow portion of flow time may be determined from Figure 8.03a. The flow time (in minutes) in the channel can be estimated by calculating the average velocity in feet per minute and dividing the length (in feet) by the average velocity. Step 4. Determine the rainfall intensity, frequency, and duration (Figures 8.03b through 8,03g source: North Carolina State Highway Commission: Jan. 1973). Select the chart for the locality closest to your location. Enter the "duration" axis of the chart with the calculated time of concentration, Tc. Move vertically until you intersect the curve of the appropriate design storm, then move horizontally to read the rainfall intensity factor, i, in inches per hour. Step S. Determine peak discharge, Q (ft31sec), by multiplying the previously determined factors using the rational formula (Sample Problem 8.03a). i� McBRYDE FARM PIT USGS 41 -� iY- •�} � Jam,.
