Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Facility requesting renewal of NPDES permit. Tech Support recommends renewal of existing
limits for this permit period. In the future, due to water plant expansions, limits will have to be
revised. Background: Revised stream flow information has been obtained from Water Resources
on the 7Q10 flow estimates in the First Broad River due to proposed water plant expansions for
Shelby and Cleveland County Sanitary District. Previous WLAs had used a summer 7Q10 of 70
cfs,Water Resources has determined that the 7Q10 will be reduced to 44.3 cfs at the WWTP
discharge point. Facility has been notified by letter (11/20/92) of anticipated revisions in effluent .

Facility Name SHELBY-BROAD RIVER WWTP Permit # NC0024538_ Pipe # 001 _
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 _12_% (defined as treatment two in the North Carolina procedure document). The permit holder shall perform
quartery monitoring using this procedure to establish compliance with the permit condition. The first test will be
performed after thirty days from the effective date of this permit during the months of_
FEB MAY AUG NOV_. 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 suitable test results will constitute
noncompliance with monitoring requirements.

PART IV - EVALUATION AND RECOMMENDATIONS
The applicant, City of Shelby, is requesting renewal of its
permit for the discharge of treated wastewater. An on -site
inspection revealed satisfactoryoperation and maintenance of the
waste treatment facilities. The City is currently operating under
the constraints of JOC No. 89-01 Ad because of inabilities to
comply with the final effluent limitations for biochemical oxygen
demand (BOD5), total suspended solids (TSS), and fecal coliform.
A blackish colored effluent was prominent due to the
contribution of wastewater from textile industries. The receiving
stream is noticeably impacted due to the color.

Pending the review and approval of the wasteload allocation it
is recommended that the permit be renewed.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Facility requesting renewal of NPDES permit. Revised stream flow information has been obtained.;
from Water Resources on the 7Q10 flow estimates in the First Broad River due to proposed watel_
plant expansions for Shelby and Cleveland County Sanitary District. Previous WLAs had used a
summer 7Q10 of 70 cfs,Water Resources has determined that the 7Q10 will be reduced to 44.3 cfs
at the WWTP discharge point. Facility has been notified by letter (11/20/92) of anticipated
revisions in effluent limits.

Facility Name SHELBY-BROAD RIVER WWTP Permit # NC0024538_ Pipe # 001 _
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 _17 % (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 performed after thirty days from the effective date of this permit during the months of_
FEB MAY AUG NOV_. 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 suitable test results will constitute
noncompliance with monitoring requirements.

Box 207 - Washington at Graham St.
Shelby, North Carolina
Dear Mr. Rhom:
The Technical Support Branch has received your letter (February 17, 1993) regarding the
recalculated 7Q10 flow at the Shelby WWTP. Concern about the accuracy of the revised 7Q10 flow
is understandable considering the 37% reduction in estimated flow from 70 cfs to 44.3 cfs.
According to your letter, you thought that the water withdrawals from the Cleveland Co.
Sanitary District (CCSD) and City of Shelby had been included in the previous flow estimate of 70
cfs. It has been verified through USGS that the flow estimate given to our Branch in 1989 was
based on natural stream flow without additions or withdrawals. USGS does not know the location
of water supply intakes in relation to the gaging stations that record flow data, and therefore
these intakes are not considered in the calculations and estimates of 7Q10 flow.
The revised flow of 44.3 cfs given in the letter to Mr. Brickhouse was evaluated by the
Division of Water Resources (DWR) in our Department. Our documentation indicates that DWR
included data from a discontinued USGS gaging station on the First Broad River as well as the
proposed water withdrawals from CCSD and Shelby. We are confident that the revised estimates
are more accurate and than the 1989 flow estimates.
If you have additional questions, please contact Jackie Nowell of my staff at (919)-733-
5083 or Jim Mead or Steve Reid of DWR at (919)-733-4064.

Mr. Trevor Clements

Dear Mr. Clements:
February 17, 1993
In regard to your letter to Mr. Dallas Brickhouse of Piedmont Olsen
Hensley, concerning the 7Q10 flow of the Broad River at the
discharge of the Cities WWTP.
I have a question concerning the calculations used to determine the
flow. It appears that you have taken the total removal rate of
both CCSD and the City of Shelby, instead of using only the
additional withdrawal amount.
My opinion of the 7Q10 at the WWTP:
The 7Q10 of 1st Broad River = 70 cfs (45 mgd).
This was determined while the water plant was extracting 15.5 cfs
(10 mgd) and had been part of the 7Q10 at the WWTP.
The recalculations should be:
cfs mgd
1992 7Q10 including 10 mgd withdrawal at WTP = 70 45
1993 Expansion of Water Plant 9.3 6
1993 CCSD Water Plant Withdrawal 9.3 6
7Q10 After Water Plant Expansion 57.4 33
As I am now making application for NPDES Permit Renewal, this is
important; please advise.
Thank you for your considerations in this matter.
Sincerely,
Don Rhom,
Plant Engineer

SUBJECT: Shelby 201 Facilities Plan Amendment
Cleveland County
The Technical Support Branch has reviewed the amendment report for the
subject facility. We have no additional comments regarding the effects of
the water treatment plant expansion decreasing the 7Q10 flow Ciownstream.
The preliminary limits detailed in the November 20th letter are based. on a
reduced 7010 flow of 44.3 cfs as calculated by the Division of Water
Resources. If a lower 7Q10 flow is maintained, such as the 25 cfs men-
tioned in the letter from the Wildlife Resource C':mi;lssion, new efflne:it
limits will have to be evaluated.
Please contact me if there are any additional questions.
