circumstances prevented sampling in 2012. The sample results greatly varied between
the two sampling events so typical characteristics of the discharge were not
determined. Phase ensure that future sampling results are compared with the limits in

NORTH CAROL.INA WASTEWATER/GROUNDWATER LABORATORY CERTIFICATION APPROVED
PROCEDURE FOR THE ANALYSIS OF pH
This document provides an approved procedure for the analysis of pH per 15A NCAC 2H .0305 (a) (6) (F) and (g) (3).The
procedures in this document, in addition to all requirements of the EPA approved method found in 40 CFR Fart 130.3, must be met.
HOLDING TIME.
• Samples must be analyzed within 15 minutes of collection (40 CFR Part 136 Table 11).
METER CALIBRATION:
• Instruments are to be calibrated according to the manufacturer's calibration procedure prior to analysis of samples each day
compliance monitoring is performed.
• Use a pH meter accurate and reproducible to 01 pH unit (as demonstrated daily by acceptable performance of a check standard
buffer) with a range of 0 to 14 and equipped with temperature -compensation adjustment. The meter must be calibrated with at
least two buffers. In addition to the calibration buffers, the meter calibration must be verified with a third standard buffer solution.
The calibration and check standard buffers must bracket the ranee of the samples being analyzed. A portion of the buffer
solutions should not be used for more than one calibration. Discard any used buffer portions.
• The check standard buffer must read within f0.1 S.U. to be acceptable. If the meter verification does not read within 0.1 S.U.,
the meter must be recalibrated before any samples are analyzed.
• When performing analyses away from the certified laboratory's primary location, a post analysis calibration verification using the
check standard buffer must be analyzed at the end of the run. It is recommended that amid-day check standard buffer be
analyzed when samples are analyzed over an extended period of time. The post analysis check standard buffer(s) must read'
within t0.1 S.0 or corrective actions must be taken.
General Information
• Samples shall be gently stirred during measurement, Steps must be taken to eliminate cross contamination between
measurements (e.g., rinsing and blotting the electrode dry, dipping the electrode in stream multiple times, etc.).
• The units of measure for pH analyses are Standard Units (S,U,). It is recommended that pH be read in one -hundredths (0,01).
Values must be reported in tenths (0.1). It should be noted that many proficiency testing (PT) providers require samples be
reported to one -hundredths.
DOCUMENTATION:
The following must be documented in indelible ink whenever sample analysis is performed,
1. Date and time of sample collection.
2. Date and time of sample analysis to verify the 15 minute holding time is met. Alternatively, onetime maybe documented
for collection and analysis with the notation that samples are measured in situ or immediately at the sample site.
. Sample site including' facility name and location, ID, etc.
4. Collector's/analyst's name or initials:
. Meter calibration and meter calibration time(s).
. True values of buffers used for calibration.
. True value for the check standard buffer.
. Value obtained for the check standard buffer (verification of t 0.1 &U.):
. True value and value obtained for the post analysis calibration verification(s), where applicable.
% Report all data values to the nearest 0.1 pH unit.'
if. Traceability for chemicals, reagents, standards and consumables.
12, Instrument identification.
3. Parameter analyzed:
14, Data qualifer(s), when applicable.
1. Equipment maintenance (recommended).

Dear Pe ittee.
e facility listed above is covered' under NPDES General Permit NCG500000. NCG500000 expires
on July 31, 2007. Federal (40 CFR .22.41) and North Carolina (15A NCAC'2H.0105(e)) regulations require
that permit renewal applications must be filed at least 180 days prior to expiration of the current permit. If
you have already mailed a renewal request, you may disregard this notice.
To satisfy this requirement, the Division must receive a renewal request postmarked no later than
February 1, 2007. Failure to request renewal by this date may result in a civil penalty assessment. Larger
penalties may be assessed depending upon the delinquency of the request. This renewal notice is being sent
well in advance of the clue date so that you have adequate time to prepare your application.
f any discharge previously covered under NCG500000 will occur after July 31, 2007, the
CoC must be renewed. Discharge of wastewater without a valid permit would violate North Carolina
General Statute 14-215.1; unpermitted discharges of wastewater may be assessed civil penalties of up to
2,000 per day.
If all discharge has ceased at your facility and you wish to rescind this CoC [or if you have other
questions], contact me at the telephone number or e-mail address listed below.
