APPLICABILITY This permit is applicable to the following types of discharges defined below: 1. Non -contact cooling water and open recirculation cooling water systems used in industrial processes for the sole purpose of cooling machinery and other equipment. Non -contact cooling water is defined as water used for cooling which does not come into direct contact with any raw material, intermediate product, waste product or finished product. Contact cooling water is defined as cooling water that comes into contact with raw material, intermediate product, finished product, byproduct or waste product. Open recirculating cooling water systems, continuously reuse the cooling water which passes through the heat transfer equipment. Open recirculating cooling water system discharges to a Water Supply water body may require an individual NPDES permit. Contact cooling water discharges require an individual NPDES permit. 2. Condensate wastewater from atmospheric cooling systems. 3. Blowdown wastewaters. Blowdown is defined as the minimum discharge of recirculating water for the purpose of discharging materials contained in the water, the further buildup of which would cause concentration in amounts exceeding limits established by best engineering practice. 4. Exempt stormwater, which is defined as discharges of stormwater which do not require permits under the state or Federal NPDES programs. Exempt stormwater includes stormwater which accumulates in outdoor basins or ponds designed for cooling water or other waters covered by this permit. 5. Water associated with hydroelectric power facilities, including cooling waters, waters from sumps and drains, dam seepage and exempt stormwater. 6. Other similar wastewaters which may qualify for coverage under this General Permit. Facilities are ineligible for coverage under this General Permit if they qualify as a Major discharger, as classified by the EPA. SECTION B. (l.)

Composite Sample A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite samples may be obtained by the following methods: (1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow. (2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period of discharge and combined proportional to the rate of flow measured at the time of individual sample collection, (3) or Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at the treatment system, or (4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a constant time interval. Use of this method requires prior approval by the Director. This method may only be used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply: Page 12 of 23 DocuSign Envelope ID: A5A31D1C-527B-48C6-A13E-AE070AC8CF23 General Permit NCG500000 ➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters ➢ Influent samples shall not be collected more than once per hour. ➢ Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab samples at intervals of no greater than 20 minutes apart during any 24-hour period. ➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling period. Continuous flow measurement Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance activities on the flow device. Daily Discharge The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the "daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also "Composite Sample," above.) Daily Maximum The highest "daily discharge" during the calendar month. Daily Sampling Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that requirement will be so noted on the Effluent Limitations and Monitoring Page(s). DWR or "the Division" The Division of Water Resources, Department of Environmental Quality. Effluent Wastewater discharged following all treatment processes from a water pollution control facility or other point source whether treated or untreated. EMC The North Carolina Environmental Management Commission EPA The United States Environmental Protection Agency Facility Closure Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this permit to be rescinded. Geometric Mean The Nth root of the product of the individual values where N = the number of individual values. For purposes of calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered = 1. Grab Sample Individual samples of at least 100 mL collected over a period of time not exceeding 15 minutes. Grab samples can be collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream samples). Hazardous Substance Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the CWA. Instantaneous flow measurement The flow measured during the minimum time required for the flow measuring device or method to produce a result in that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab samples required for the same sampling period so that together the samples and flow are representative of the discharge during that sampling period.
