Compliance with the flow limit in this permit shall be documented in the following manner:
I. The Permittee shall provide and maintain a refrigerated composite sampler and primary flow
measurement device for flow proportional sampling and flow measurement of the permittee's
process wastewater discharge.
2. 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 151h 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. These records shall be available to the City of
Greensboro Industrial Waste Section during inspections or upon request.
4. Immediate notification, within 24 hours of becoming aware of the problem, shall be provided
to the Pretreatment Coordinator [336-433-7227] or Pretreatment Compliance Specialist [336-
373-3285] by phone or e-mail for any periods in which the effluent meter is inoperable with
the exception of periods for maintenance/calibration. 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]. Failure to do so will result in the Industrial Waste Section and the
Water Resources Customer Service Division reverting back to the incoming water meter to
determine compliance and billing.
6. 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.
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.
