Subject: City of Graham Wastewater Treatment Plant
NC00021211 Alamance County
Response to Comments to DRAFT NPDES Permit
A wasteload allocation was completed for this facility in November, 1995. A letter from the facility questioning
the various Permit requirements was sent in January, 1996. This memorandum represents the Instream
Assessment Unit response.
2. Section. Part I
a. 'Mercury -Limit of 0.09 jig/L. The City requests that this be changed to monitor only deleting the
numerical limit. In the past the City has performed mercury analysis in-house at various detection
levels with the most current at<0.5 ppb. I understand that current laboratory technology allows for
a detection level of <0.2 ppb. The City began having its monthly mercury analysis performed at a
commercial lab at the lower detection level in October, 1995. Therefore, we do not believe
enough data exists to warrant a limit at this time and requests (sic) deletion of the numerical limit.'
We cannot concur with this request. As noted on the Fact Sheet for this review, 4 out of 18
samples for mercury were above detection with a maximum value of 8.0 µg/I submitted in April,
1995.
c. 'Stream Monitoring-The process of reaching an agreement with the City of Burlington to
coordinate stream data collection and reporting has begun. However, at this time a final agreement
has not been reached. Please, instruct us on how to complete, report, and comply with our permit
when an agreement is finalized.'
During the process of basin-wide permit review, both the Burlington-South (NC0023876) and
Burlington-East(NC0023868) plants and the City of Graham plant were found to be monitoring
instream at overlapping sites. In an effort to mitigate this duplication of effort and to gain more
useful instream monitoring information,we recommended a coordinated instream monitoring
program be established between all three of these facilities. The attached map, (not to scale)
portrays where these sites are and the duplication of effort which exists among these three
facilities.

Response to Comments to DRAFT NPDES Permit NC0021211
The current instream monitoring recommendations were required independently of a
coordinated monitoring effort. If an agreement to coordinate stream monitoring is reached
between the three facilities collectively, the seven instream monitoring sites are as follows:
1) SR 1712 (Hopedale Road)
2) Highway 54
3) SR 2158 (bridge over Haw River)
4) Highway 87 (bridge over Big Alamance Creek)
5) SR 2116 (bridge over Big Alamance Creek)
6) Saxapahaw Lake (above dam)
7) SR 1005
These sites should be monitored for temperature, dissolved oxygen, fecal coliform, total
phosphorus, and orthophosphate. Stream samples shall be collected three times per week
during June, July, August, and September and once per week during the remaining months of
the year. Orthophosphate need only be taken during the months of June, July, August, and
September. Effluent monitoring of total phosphorus and orthophosphate needs to take place
on the same days that the instream samples are taken.
Efforts should be made to collect these samples at each location on the same day and at the
same time of day every time a sample run is made. It.should also be noted that instream
monitoring for BOD5 and NH3-N have been removed from our recommendations.
When the cities of Burlington and Graham have decided how to coordinate their instream
monitoring of the above sites, a request for permit modification will need to be submitted for
each facility.
e. 'Other Metals -The City requests that the frequency of sampling for copper, lead, cyanide,and zinc
be changed from 2/month to 1/month.'
Lead and cyanide are being monitored in the facility's Long Term Monitoring Plan (LTMP)
through Pretreatment and this LTMP sampling should provide the necessary data required.
Therefore, we recommend that the requirements for lead and cyanide be dropped from the -
NPDES permit.
Copper and zinc can be changed to once per month monitoring, but should be kept in the
NPDES permit requirements.
Please let us know if we can be of more assistance.

b. B.(6j. " AUTHORiZATiON TO CONSTRUCT," the language of this section
implies that the City must determine and approve the upgrades of any Industrial
Users' pretreatment facility upgrades_. The City while willing to assist our industrial
clients' pretreatment needs does_ not wart to be responsible for their upgrade that
may cr may not correct their p:oblern. The wording a this section appears to mean
that the City could be financially and/or legally injured if the industry elects a process
that does not workout. Clarification of the evaluation requirement is needed for t'ne
Cdy to comply.
Section 7b Clarification is needed for definition of "sampling for organic compounds."
Si5ecificaiiy, what parameters need to be sampled?
d Section 14. Clarification is needed as to "modification to pretreatment program shall
be considered a permit modification." Is this referring to the industrial permit issued by
the City to the industry or the Citv's NPDES permit?

SLUDGE MANAGEMENT PLAN
CITY OF GRAHAM WASTEWATER TREATMENT PLANT
NPDES PERMIT No. NCO021211
• Wastewater Treatment Plant sludge is aerobically digested,lime-stabilized,and then surface applied
to a dedicated land application site.
• Aerobic digestion takes place in the primary and secondary digesters(combined volume of 375,900
gallons). The digested sludge is the lime stablized by adding approximately 1.4 tons of lime per
48,000 gallons of sludge(sludge pH is raised to 12.0 standard units for 2 hours and then held at 11.5
pH for an additional 22 hours minimum). Two lime stabilization tanks(combined volume of 100,000
gallons)are utilized for this process. Sludge can then be pumped directly to the Transport truck or
diverted to storage in one 200,000 gallon storage basin.
• Stabilized sludge is transported in one of two sealed tanker trucks to the land application site.The
vehicle that is used carries a copy of the Non-Discharge permit and spill control and prevention
policy. Remote routes are used and equipment meets DOT standards.Drivers are trained and
educated concerting operational components of the permit and receiver site procedures.Drivers have
CDL license with tanker and air brake certifications.
• The land application site is dedicated city owned land. There are 89.4 acres of land that is permitted
under Non-Discharge permit No. W00003824. Sludge is surface applied in accordance with the
permit restrictions using an off road high-wheeler with sealed tank.
• A fescue cover crop is maintained on the fields and is harvested and used for cattle feed. Fields are
maintained and crops harvested in accordance with permit restrictions.
• Nutrient and metal loading rates and application rates are calculated and reported in accordance with
W00003824 requirements.
• All land application activities are performed in accordance with W00003824 requirements and 40
CFR Part 503 federal regulations. The permit was reissued on June 28, 1995 and will expire on May
31, 1995.
If you have any questions or require additional information please call me at 910-578-3264 or write to my
attention at the above address.

Wasteload Allocation Summary
(approach taken,correspondence with region, EPA,etc.)
Pe n�: 3•�gP c `T -- -`^urlington-East,Graham,and Burlington
-South were reviewed and allocated based upon a new toxics pro cedure utilizing a statistical review and
analysis of current effluent data
The current permit requirements for Burlington-East,Graham,and Burlington-South collectively contain
seven instream monitoring sites, (some which are monitored by two different facilities) : SR 1712
(Hopedale Road),Highway 54,SR 2116(bridge over Haw River),Highway 87(bridge over Big Alamance
Creek),SR 2116(bridge over Big Alamance Creek),Saxapahaw Lake(above dam),and SR 1005.
Recommendations for permit renewals will not change these sites, but the Technical Support Branch
requests these facilities coordinate instream monitoring under the guidance of the Winston-Salem Regional
Office. Recommendations from the Technical Support Branch would be a collective effort to monitor
instream on the same day and if possible at the same time of day.
Recommendations for parameters to be monitored instream will change for some of these permits. For
example, those permits which previously contained BODS and NH3-N monitoring will no longer be
required to take these samples. Instead, all three of these permits will need to take instream TP and
orthophosphate samples as well as temperature,dissolved oxygen,fecal coliform,and conductivity.

Facility Name City of Graham Waste Water Treatment Plant Permit # NCO021211 Pipe # 001
CHRONIC TOXICITY PASS/FAH. 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 14 % (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 fast test will be performed after thirty days from the effective date of this permit during
the months of Mar., Jun., Sep., and Dec Effluent sampling for this testing shall be performed at
the NPDES permitted final effluent 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 survival and appropriate environmental controls, shall constitute an invalid test and will require
immediate retesting(within 30 days of initial monitoring event). Failure to submit suita a test results will
constitute noncompliance with monitoring requirements.

1987: 3.5 mgd discharge to Town Branch w/12/4/5 limits;limits for Cd, Cr, Pb,CN plus toxicity test and metals monitoring
1988: Questions of sampling techniques and lab analysis which indicated high metals values both at the effluent and instream.
Rigorous protocol and instream sampiing was undertaken which resulted in much lower values than previously seen.
Continued monitoring and limits were required. Facility put under SOC for not meeting metals limits.
1989: 3.5 mgd discharge to Town Branch w/12/4/5 limits; limits for Cd, Ni, Pb, CN plus toxicity test and metals monitoring. it was
during this renewal that the limits were determined based on interaction between the Burlington- East and Burlington-South
discharges. The Cr and CN limits were determined by adding all the discharges together and using a dilution equation with a
s7Q10 of 42 cis, (flow statistic just prior to confluence with Alamance Creek). The Ni and Pb limit was given at the standard
because it was thought that all the assimilative capacity for these metals was used up.

The current permit requirements for Burlington - East, Graham, and Burlington- South collectively contain seven instream
mdnitoring sites, (some which are monitored by two different facilities) : SR 1712 (Hopedale Road), Highway 54, SR 2116
(bridge over Haw River), Highway 87 (bridge over Big Alamance Creek), SR 2116 (bridge over Big Alamance Creek),
Saxapahaw Lake(above dam), and SR 1005.
Recommendations for permit renewals will not change these sites, but the Technical Support Branch requests these
facilities coordinate instream monitoring under the guidance of the Winston - Salem Regional Office. Recommendations
from the Technical Support Branch would be a collective effort to monitor instream on the same day and if possible at the
same time of day.
Recommendations for parameters to be monitored instream will change for some of these permits. For example, those
