The effluent process flow meter readings shall be recorded daily and the daily effluent flow calculated in gallons per day. Flow measurement records shall be submitted to the City of Greensboro Industrial Waste Section monthly. Data is to be submitted by the 15th of each month for the previous month's flow measurements. 3. The permittee shall maintain permanent flow records and maintenance and calibration records on-site for a minimum of three years.

This notification shall include the cause of the malfunction/failure, anticipated repair time and/or plan of action to allow the permittee to comply with the requirement to record the flow meter readings daily. 5. Malfunction/failure of effluent flow meters that are used for sewer billing purposes shall also be immediately reported, within 24 hours of becoming aware of the problem, to the Water Resources Customer Service Division by phone---Assistant Manager [336-373-4108] or Manager [336-373-2639].

The wastewater meter must have a non-resettable totalizer that reads in cubic feet or gallons. There shall be no by-pass capability of the wastewater metering devices and monitoring point(s). 7. If the wastewater meter is being used for billing or compliance, it must have permanent flow records (i.e. strip chart recordings) that include at minimum the following basic information: date, time, totalizer reading (with units), interval flow volume (with units), maximum flow rate (with units), and primary measuring device type. Any interruption in such records with the exception of periods for maintenance/calibration are a violation of this permit and may result in a civil penalty each day the interruption is allowed to continue. September 1, 2023 Permit Renewal Page 7, SIU Permit#P043 ZINK HOLDINGS, LLC. Effective September 1, 2023 8. The wastewater meter shall have a back-up power source (battery or generator) to ensure uninterrupted measurement of the discharge flow in the event of a power failure unless loss of power automatically prevents any discharge from the facility. The back-up source shall provide power to the wastewater meter's sensor and permanent flow records for a minimum of 12 hours. B. RESTRICTED DISCHARGE ZINK shall at no time discharge wastewaters generated from the"Active" cyan layer or magenta layer. This wastewater is to be disposed of offsite with commercial hauler.

FLOW MEASUREMENT CALIBRATION/VERIFICATION Flow meters used for flow monitoring under this permit shall be calibrated in accordance with manufacturer's recommendation by an independent contractor or a Greensboro Industrial Waste Section approved in-house technician. Calibration documentation shall be maintained for a minimum of three (3) years and made available upon request and during on-site inspections. 1. Industries with a highly-accurate (<0.5% variance) flow meter, such as a magnetic or ultrasonic (Doppler and transit) meter, must have the meter calibrated/verified once every five years. 2. Industries with effluent wastewater meters that are used for City of Greensboro sewer billing purposes, must calibrate the meters annually. Permanent records in the form of electronic data trend sheets, strip or circular chart recordings that have back-up and fail- safe capabilities are also required to be maintained. 3. Any industry may conduct meter calibration more frequently than required in this permit. The following flow meters/systems have no calibration requirements: 1. Industries with custom built Memtek©pretreatment systems have a permanently calibrated flow measurement system (as long as the plumbing remains intact and the viscosity of the liquid does not change) and no calibration is required. 2. Industries with a non-discharge closed-loop system are not required to have any meter on the system calibrated. 3. Industries that record daily flow from a City of Greensboro owned, maintained, and calibrated incoming potable water meter are not required to have the meters calibrated. 4.
