Dear Mr. Clements:
Enclosed herewith please find a copy of the analysis for priority
pollutants in accordance with Part III Section J of NPDES permit
NC0023868. Should you have any questions or need further
information, please feel free to contact me at (919) 222- 5133.

Annual Pollutant Analysis Monitoring Requirement
Reporting Form A
(Revised June 1990)
1. Facility Information:
Page 1 of 9
NPDES Permit No: NC O023868 Discharge (Pipe) No: 01 Year. 1991
Facility Name: East Burlington WWTP Class: TV County: Alamance
Person(s) Collecting Samples: Allen D. Isley
Status of facility wastewater treatment operation on day of sampling: typical: _X_ Yes No
If no, explain briefly:
Analytical Laboratory: Research & Analytical Lab
II. Sampling:
24 hr composite for main sample / grab sample for purgeable fraction
Date Sampled: (composite sample) Corresponding sample taken for toxicity testing:
Sampling begun (date, time): 8/8/91 12:00 am X Yes
Sampling finished (date, time): 8 / 9 / 91 12 : 00 am No
Date and time sampled (grab sample): 8 / 9 / 91 9 : 00 am
Instructions
The purpose of this document and the accompanying memo is to standardize the sampling, analysis and reporting procedures to be used
for the Annual Pollutant Analysis Monitoring (APAM) Requirement as described in the permit.
Sampling
1 - Take a 24-hour composite sample from the final effluent during mid -week (Wednesday through Friday). Collect a grab sample for the volatile
organic fraction when collection of the 24-hour composite sample is completed. Follow any other sampling instructions provided by the laboratory
performing the analysis.
2 - Indicate in the space provided at the top of this page whether a corresponding sample for toxicity testing was taken.
3 - Make note of any unusual wastewater treatment operating conditions occurring on the day of sampling in the space provided on the form.
Analysis
4 - Analyze the effluent for pollutants listed on the APAM form, including those to be identified and approximately quantified under the 10
significant peaks rule, using appropriate EPA -approved methods for each of the analytic fractions. Other analytical methods can be substituted
only with prior, written approval of the Director of the Division of Environmental Management (DEM). Read and distribute to the laboratory
performing the analysis the accompanying memo (Tedder, October 1990), clarifying analytical requirements.
5 - Identify chemicals to be analyzed for according to the 10 significant peaks rule (as described in item 2 of the Annual Pollutant Analysis
Monitoring Requirement in the permit) using a GCIMS library search. Tentative identification is all that is required; confirmation by standard
injection is not necessary. Estimate the concentration of each based on an internal standard having the closest retention time.
Reporting
6 - Quantitation Limit Targets that should be met are listed on this Revised APAM Reporting Form A. Report the use of any higher quantita-
tion limit and an explanation as to why the listed quantitatlon limit target could not be met. Examples of acceptable reasons for not meeting
a quantitation limit -target could be high background concentrations in a sample, or the necessity for sample fraction dilution to bring a chemical
to within a quantifiable concentration. List any quantitation limit differtent (whether higher or lower) from the target in the column provided
for this purpose.
7 - If a chemical is found to be below the quantitation limit, report the concentration detected as less than (or'<') the quantitation limit
in the appropriate space. Provide a concentration estimate for chemicals detected In concentrations greater than the detection limit and less
than the quantitation limit. Enter the detection limit in parentheses beside the estimate. Chemicals detected In concentrations above the quan-
titation limits must be quantified. Quantitation limit and detection limit are defined in the accompanying memo (Tedder, October 1990). Enter
the total number of peaks detected in each analytic fraction in the appropriate space on this Revised APAM Form A. Report all concentrations
in units of micrograms per liter (ug11) and metals as total recoverable metal. If no peaks to be identified under the 10 significant peaks rule
are observed, enter "none" in the space provided for "other" compounds in each appropriate analytic fraction section. Provide the concentra-
tion estimate and retention time for "unknowns" as well as for "significant peaks" for which a structural assignment can be made.
8 - If "significant peaks" are found, provide probable molecular weight, library match probability, retention time, identification basis, and
MS scan number for each. In addition, list internal standards and their retention times.
9 - In the section labeled "Organic Analytical Information" (p. 9), Include for each organic fraction the method, extraction technique, GC
operating conditions, and surrogate recovery. Report the size of the GCIMS library being utilized in the appropriate space.
10 - Use copies of this Annual Pollutant Analysis Monitoring Revised Form A to report the results of the analysis. Both the analytical laboratory
representative and the facility operator in responsible charge should sign completed forms (last page).
11 - Mail two completed copies of the form (and the laboratory report, if submitted to the facility on a different form) to: ATTN: Central Files,
Division of Environmental Management, NC DEHNR, P.O. Box 27687, Raleigh, NC 27611. Mail the APAM form separately from Discharge Monitoring
Reports.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Facility continues to upgrade according to staff report. Is dechlorination part of the plant
improvements? Several toxicants were documented in the effluent at levels which require further
monitoring and/or a limit. They are: Cd, Cr, Cn, Hg, Ag, Chloride, Fluoride, and Bis(2-
ethylhexyl) phthalate. The fecal limit should be changed to 200/100 ml.

CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay
Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality
is _50 % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform
Quarterly monitoring using this procedure to establish compliance with the permit condition. The first test will be
performe after thirty 4ays from the effective date of this permit during the months of
F a v ✓ . Effluent sampling for this testing shall be performed at the NPDES
permitted final a went discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DEM Form AT-1(original) is to be sent to the following address:
Attention_: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity
sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Environmental Management indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
I urvival and appropriate environmental controls, shall constitute an invalid test and will require immediate
retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.
