IV ADDITIONAL FLOW OR REALLOCATION OF EXISTING FLOW 2
Additional flow:or reallocation of existing flow is avaliable to facilities that are owned by a
unit of Government. Please be advised that additional flow will be allowed under an SOC
amendment only in extreme circumstances. These circumstances include elimination of other
discharges that are noncompliant with their NPDES Permit or continual noncompliance of
the flow parameter as specified in the original SOC. These circumstances do not include
failure by the facility to properly remove Infiltration and Inflow. When requesting the
additional flow, the facility must include justification why this flow is needed and su rtin
g
documents to show what has been done to eliminate any flow problem causes (ie efforts
undergone to eliminate inflow and infiltration into the plant). If the requested addtional flow
is non -domestic, then the facility must be able to demonstrate the ablility to effectively treat
the waste and that the waste will not adversely impact the wastewater system or its
ablility to dispose of or utilize residuals. The non -domestic waste must be simular to
domestic strength either before pretreatment or after pretreatment. The applicant must
provide a detailed analysis of all parameters that can reasonably be expected to be containein
the proposed non -domestic wastewater. The total domestic additional flow requested
is zer gallons per day. The total non -domestic flow requested is
zero allons per day. The total additional flow is zero
gallons per
day. (NOTE: Existing SOC permits 9.0 MGD monthly average)
If a reallocation of existing addtional flow is needed then the facility must provide
justification as to why this reallocation is needed.

APPENDIX B
APPLICATION FOR AN AMENDMENT TO A SPECIAL ORDER BY CONSENT
CITY OF MONROE WASTEWATER TREATMENT PLANT
EXPLANATION AS TO WHY SOC AMENDMENT IS NEEDED
The City of Monroe is requesting an amendment to items 2(b)(2) and
2(b)(3) of the compliance schedule of Special Order by Consent EMC
WQ No. 90-08 Ad I by an extension of three months as follows:
2) Complete construction by December 31, 1993.
3) Attain full compliance with final Permit limits by March
31, 1994.
This'Amendment does not request an extension of the expiration date
of the revised Special Order by Consent currently scheduled to
expire on March 31, 1994.
The revised SOC issued in February 1992 required constructidn to be
completed by September 30, 1993. At the time this revised SOC was
issued, design of the wastewater treatment plant improvements to
comply with the SOC were nearly completed by Hazen & Sawyer
Engineers. The design was submitted to NCDEM with Request for
Authorization to Construct in April 1992, and after receiving
appropriate authorization from NCDEM, bids were advertised in July
and received on August 18, 1992. The contracts as.bid allowed a
construction time of 11 months and was based on Hazen & Sawyer's
opinion of the minimum time necessary for a qualified contractor in
this work. Contracts were executed on October 14, 1992, after time
was .permitted for approval of contract award was 'received from
NCDEM's Construction Grahts and Loans Section. The Contractors'
initial completion date; based on date of contract execution, was
defined as September 20, 1993. Therefore, as of the beginning date
of construction, there was less than two weeks contingency for
events beyond the control of contractor before the SOC completion
date.
Two significant issues have impacted the contractors. beyond their
control or the City's control since construction was initiated.
These issues include (1) statistically abnormally wet weather
during the period of November 1992 through March 1993; and (2)
piping modifications required in current contracts to be compatible
with plant expansion design. These two issues are explained below
in detail.
Wet weather delay has- been addressed to the City by Haren
Construction based on rainfall between November and March. This
period was a critical period in the contractor's schedule to
perform pipeline installation and production concrete work and was
the type work which is highly dependent bn weather. The City asked
Hazen & Sawyer to critically evaluate this request based on factual
comparison of actual weather *during construction to normal weather

APPENDIX B -- PAGE 2
information for this season and recommend only the minimum
additional time necessary to establish a legally defensible
position. Hazen & Sawyer has recommended 32 additional days.
Rainfall amounts between November 1992 and March 1993 in Monroe was
an average 79.5% higher than statistical averages established by
NOAA at Charlotte/Douglas Airport, and the spacing of rainfall
events resulted in several periods of significant delays to the
Contractor. Rainfall in March 1993 was 8.43 inches, or 96.2% of
the highest March total on record at CLT.
The piping modifications resulted from progress by Hazen & Sawyer
on the design of a plant expansion from 7.0 MGD to 9.0 MGD. Upon
completion of surveying and geotechnical investigation, Hazen &
Sawyer identified the need to change the preliminary layout of a
new aeration basin for the plant expansion, and this change
conflicted with the location of several pipes to be constructed
under the current contract. A change order has since been
executed, with the approval of NCDEM's Construction Grafts and
Loans Office, to modify the piping -to conform to the design layout
of the plant expansion. The modified piping .plan has two
significant advantages: (a) it substantially reduced the need for
temporary plant shutdowns during the upcoming expansion
construction thereby significantly reducing the risk of plant
stress or upset; and (b) it yielded an overall reduction in cost to
the combined two phases of construction. Haren Construction
initially requested 47 days time extension to construct the
modified piping, Hazen & Sawyer and the City reduced the time to 21
days through active negotiating. Hazen & Sawyer'has since advised
the City that the actual impact of the modified work, based upon
daily construction logs), was closer to the original 47 days
initially requested.
The City intends to maintain close inspection and review of the
contractors' remaining work to provide the earliest possible
completion date consistent with the contractor's legal rights of
relief in additional time for -events beyond the contractors'
control. The additional time requested in this SOC amendment is
necessary to provide for the specific events defined in detail
above and to assure effective administration of the completion of
the construction consistent with the provisions of the construction
contracts without the anticipated need .for any further SOC
amendment.

APPENDIX C
APPLICATION FOR AN AMENDMENT TO A SPECIAL ORDER BY CONSENT
CITY OF MONROE WASTEWATER TREATMENT PLANT
EXPLANATION OF ACTIONS TAKEN TO AVOID NONCOMPLIANCE WITH SOC
As of this date, the City of Monroe has maintained compliance with
the existing SOC with the exception of the parameters listed in
Appendix A. Listed violations of cadmium and lead have been
corrected by industrial pretreatment control and have been in
continuous compliance for the past nine months. A single monthly
violation of flow in March 1993 was due to an extremely abnormal
period of frequent and heavy rainfall; the City proposes in the
current fiscal year to perform some I/I flow monitoring during the
wetter season to determine if some sources of I/I can be cost-
effectively removed. Ammonia violations in the summer of 1993 have
been effectively traced to industrial wastes from the Union County
sewer collection system and the City is actively pursuing a
compliance schedule with the County to effectively provide
permanent control. In .addition, Hazen & Sawyer completed an
evaluation of ammonia in August 1993 to confirm this cause.
The City has met the schedule•. for all construction activities to
date in the SOC but will not meet the construction completion date
of September 30, 1993 for the reasons described in detail in
Appendix B. However, by this date the City does expect all yard
piping to be installed, the new Centrifugal Blowers to be certified
and in service, and the fine bubble diffusers to be installed,
certified, and in service for one of the four aeration basins.
It is possible but not certain that a second aeration basin can be
complete by September 30. As these new aeration basins are phased
into service one -at -a --times, the City will take maximum advantage of
the new equipment fl xe ibility to optimize treatment of •the
wastewater through the plant, thereby minimizing (consistent with
achievable construction progress and equipment start-up "bugs"
which. are the responsibility of contractors) any real effect this
SOC amendment will have on plant effluent quality in the coming
months.
Delays in construction have been the result of weather and
necessary construction piping modifications, which are explained in
detail in Appendix B.
The City will provide all reasonable controls .to see remaining
construction completed in the shortest achievable time by the use
of progress meetings and full-time inspection. In addition, the
City invited a Regional Office representative of NCDEM to a recent
progress meeting to permit NCDEM to directly advise the contractors
of the seriousness of completing construction as soon as possible.

Re: Monroe WWTP Improvements
Contract No. 1 A
Change Order No. 1
H&S No. 3516
Enclosed is a review copy of Change Order No.-1. The additional work items
are required to accommodate and facilitate construction of the 9 mgd upgrade which
is presently being designed. In most cases, failure to make the modifications
proposed herein would result in unnecessary cost increases for the next construction
phase. We have included the Change Order proposal as sent to us from Haren
Construction Company as well as the results of our independent cost estimate.
The -Contractor's price increases and time extension indicated in this change
order are the final figures resulting from a lengthy period.of discussion and negotiation
between Haren Construction and Hazen and Sawyer. We feel that the Contractor's
revised Change Order prices are legitimate and reflective of the costs for the work.
We are recommending that the net change in contract amount and time of
completion be approved. Haren had originally requested 47 days time extension, but
agreed to a reduced time extension of 21 days because the City mustmeet the SOC
schedule. We feel that Haren Con,siruction has been extremely cooperative in these
negotiations. Please review the proposal and reply as soon as possible such that the
work progress will not be delayed.
if you have any questions, please contact us.
Very truly yours,

RE: Request for Extension of
Contract Completion Date
Monroe, NC
Dear Mr. Jones:
We have discussed with John Nemcik and Joe Martin in the past few
months, the possibility of granting an extension to the completion
date of our present contract to compensate for the lost work days
during the winter months. We have obtained records that shot, the
normal rainfall, and records from the City Of Monroe, NC that show
their records of actual rainfall received on a monthly basis.
Copies of these records are attached for your review and use in
evaluating this request. In your review, you will notice that
although the number of days that rain fell was -not abnormally high,
the amount of rain that fell on these days was nearly double that
of normal levels recorded for these same months for four months out
of a six month period.. These high volume rainfalls impeded our
ability of proceed with layout, excavation, and concrete pours.
When these torrential downpours came, the ground and. earth took
twice as long to dry to woryng conditions than if normal rainfall
had been received.
This has prompted this request for extending our contract
completion date to 11-12-93, which would add 32 days to the
existing contract total. Please call if additional information is
required and let us know if these days can be added so that we can
plan accordingly.
Res
ectfully,
Zfcg

IV ADDITIONAL FLOW OR REALLOCATION OF EXISTING FLOW?
Additional flow or reallocation of existing flow is avaliable to facilities that are owned by a
unit of Government. Please be advised that additional flow will be allowed under an SOC
amendment only in extreme circumstances. These circumstances include elimination of other
discharges that are noncompliant with their NPDES Permit or continual noncompliance of
the flow parameter as specified in the original SOC. These circumstances do not include
failure by the facility to properly remove Infiltration and Inflow. When requesting the
additional flow, the facility must include justification why this flow is needed and supporting
documents to show what has been done to eliminate any flow problem causes (ie.efforts
undergone to eliminate inflow and infiltration into the plant). If the requested addtional flow
is non -domestic, then the facility must be able to demonstrate the ablility to effectively treat
the waste and that the waste will not adversely impact the wastewater system or its
ablility to dispose of or utilize residuals. The non-dornestic waste must be simular to
domestic strength either before pretreatment or after pretreatment: The applicant must
provide a detailed analysis of all parameters that can reasonably be expected to be containein
the proposed non -domestic wastewater. The total domestic additional flow requested
is zero gallons per day. The total non -domestic flow requested is
z e r o Qall ons .per day. The total additional flow is zero
gallons per
day (NOTE: Existing SOC permits 9.0 MGD monthly average)
If a reallocation of existing addtional flow is needed then the facility must provide
justification as to why this reallocation is needed.

'APPENDIX B
APPLICATION FOR AN AMENDMENT TO A SPECIAL ORDER BY CONSENT
CITY OF MONROE WASTEWATER TREATMENT PLANT
EXPLANATION AS TO WHY SOC AMENDMENT IS NEEDED
The City of Monroe is requesting an amendment to items 2(b)(2) and
2(b)(3) of the compliance schedule of Special Order by Consent EMC
WQ No. 90-08 Ad I by an extension of three months as follows:
2) Complete construction by December 31, 1993.
3) Attain full compliance with final Permit limits by March
31, 1994.
This Amendment does not request an extension of the expiration date
of the revised Special Order by Consent currently scheduled to
expire on March 31, 1994.
The revised SOC issued in February 1992 required constructidn to be
completed by September 30, 1993. At the time this revised SOC was
issued, design of the wastewater treatment plant improvements to
comply with the SOC were nearly completed by Hazen & Sawyer
Engineers. The design was submitted to NCDEM with Request for
Authorization to Construct in April 1992, and after receiving
appropriate authorization•from NCDEM, bids were advertised in July
and received on August 18, 1992. The contracts as bid allowed a
construction time of 11 months and was based on Hazen & Sawyer's
opinion of the minimum time necessary for a qualified contractor in
this work. Contracts were executed on October 14, 1992, after time
was permitted for approval of contract award was •received from
NCDEM's Construction Grahts and Loans Section. The Contractors'
initial completion date; based on date of contract execution, was
defined as September 20, 1993. Therefore, as of the beginning date
of construction, there was less than two weeks contingency for
events beyond the control of contractor before the SOC completion
date.
Two significant issues have impacted the contractors.beyond their
control or the City's control since construction was initiated.
These issues include (1) statistically abnormally wet weather
during the period of November 1992 through March 1993; and (2)
piping modifications required in current contracts to be compatible
with plant expansion design. These two issues are explained below
in detail.
Wet weather delay has been addressed to the City by Haren
Construction based on rainfall between November and March. This
period was a critical period in the contractor's schedule to
perform pipeline installation and production concrete work and was
the type work which is highly dependent bn weather. The City asked
Hazen & Sawyer to critically evaluate this request based on factual
comparison of actual weather 'during construction to normal weather

APPENDIX B - PAGE 2
information for this season and recommend only the minimum
additional time necessary to establish a legally defensible
position. Hazen & Sawyer has recommended 32 additional days.
Rainfall amounts between November 1992 and March 1993 in Monroe was
an average 79.5% higher than statistical averages established by
NOAA at Charlotte/Douglas Airport, and the spacing of rainfall
events resulted in several periods of significant delays to the
Contractor. Rainfall in March 1993 was 8.43 inches, or 96.2% of
the highest March total on record at CLT.
The piping modifications resulted from progress by Hazen & Sawyer
on the design of a plant expansion from 7.0 MGD to 9.0 MGD. Upon
completion of surveying and geotechnical investigation, Hazen &
Sawyer identified the need to change the preliminary layout of a
new aeration basin for the plant expansion, and this change
conflicted with the location of several pipes to be constructed
under the current contract. A change order has since been
executed, with the approval of NCDEM's Construction Grafrts and
Loans Office, to modify the piping.to conform to the design layout
of ,the plant expansion. The modified piping plan has two
significant advantages: (a) it substantially reduced the need for
temporary plant shutdowns 'during the upcoming expansion
construction thereby significantly reducing the risk of plant
stress or upset; and (b) it yielded an overall reduction in cost to
the combined two phases of construction. Haren Construction
initially requested 47 days time extension to construct the
modified piping, Hazen & Sawyer and the City reduced the time to 21
days through active negotiating. Hazen & Sawyer has since advised
the City that the actual impact of the modified work, based upon
daily construction logs) was closer to the original 47 days
initially requested.
The Cityintends to maintain close inspection and review of the
contractors' remaining work to provide the earliest possible
completion date consistent with the contractor's legal rights of
relief in additional time for events beyond the contractors'
control. The additional time requested in this SOC amendment is
necessary to provide for the specific events defined in detail
above and to assure effective administration of the completion of
the construction consistent with the provisions of the construction
contracts without the anticipated need for any further SOC
amendment.

APPENDIX C
APPLICATION FOR AN AMENDMENT TO A SPECIAL ORDER BY CONSENT
CITY OF MONROE WASTEWATER TREATMENT PLANT
EXPLANATION OF ACTIONS TAKEN TO AVOID NONCOMPLIANCE WITH SOC
As of this date, the City of Monroe has maintained compliance with
the existing SOC with the exception of the parameters listed in
Appendix A. Listed violations of cadmium and lead have been
corrected by industrial pretreatment control and have been in
continuous compliance for the past nine months. A single monthly
violation of flow in March 1993 was due to an extremely abnormal
period of frequent and heavy rainfall; the City proposes in the
current fiscal year to perform some I/I flow monitoring during the
wetter season to determine if some sources of I/I can be cost-
effectively removed. Ammonia violations in the summer of 1993 have
been effectively traced to industrial wastes from the Union County
sewer collection system and the City is actively pursuing a
compliance schedule with the County to effectively provide
permanent control. In .addition, Hazen & Sawyer completed an
evaluation of ammonia in August 1993 to confirm this cause.
The City has met the schedule for all construction activities to
date in the SOC but will not meet the construction completion date
of September 30, 1993 for the reasons described in detail in
Appendix B. However, by this date the City does expect all yard
piping to be installed,' the new Centrifugal Blowers to be certified
and in service, and the fine bubble diffusers to be installed,
certified, and in service for one of the four aeration basins.
It is possible but not certain that a second aeration basin can be
complete by September 30. As these new aeration basins are phased
into service one -at -a -time, the City will take maximum advantage of
the new equipment flexibility to optimize treatment of the
wastewater through the plant, thereby minimizing (consistent with
achievable construction progress and equipment start-up "bugs"
which are the responsibility of contractors) any real effect this
SOC amendment will have on plant effluent quality in the coming
months.
Delays in construction have been the result of weather and
necessary construction piping modifications, which are explained in
detail in Appendix B.
The City will provide all reasonable controls to see remaining
construction completed in the shortest achievable time by the use
of progress meetings and full-time inspection. In addition, the
City invited a Regional Office representative of NCDEM to a recent
progress meeting to permit NCDEM to directly advise the contractors
of the seriousness of completing construction as soon as possible.

Re: Monroe WWTP Improvements
Contract No. 1 A

H&S No. 351.6 •
Enclosed is a review copy of Change Order No. 1. The additional work items
are required to accommodate and facilitate construction of the 9 mgd upgrade which
is presently being designed. . In most cases, failure to make the modifications
proposed herein would result in unnecessary cost increases for the next construction
phase. We have included the Change Order proposal as sent to us from Haren
Construction Company as well as the results of our independent cost estimate.
The -Contractor's price increases and time extension indicated in this change
order are the final figures resulting from a lengthy period of discussion and negotiation
between Haren Construction and Hazen and Sawyer. We feel that the Contractor's
revised Change Order prices are legitimate and reflective of the costs for the work.
We are recommending that the net change in contract amount and time of
completion be approved. Haren had originally requested 47 days time extension, but
agreed to a reduced time extension of 21 days because the City must meet the SOC
schedule. We feel that Haren Construction has been extremely cooperative in these
negotiations. Please review the proposal and reply as soon as possible such that the
work progress will not be delayed.
If you have any questions, please contact us.

RE: Request for Extension of
Contract Completion Date
Monroe, NC
Dear Mr. Jones:
We have discussed with John Nemcik and Joe Martin in the past few
months, the possibility of granting an extension to the completion
date of our present contract to compensate for the lost work days
during the winter months. We have obtained records that show the
normal rainfall, and records from the City Of Monroe, NC that show
their records of actual rainfall received on a monthly basis.
Copies of these records are attached for your review and use in
evaluating this request. In your review, you will notice that
although the number of days that rain fell was not abnormally high,
the amount of rain that fell on these days was nearly double that
of normal levels recorded for these same months for four months out
of a six month period. These high volume rainfalls impeded our
ability of proceed with layout, excavation, and concrete pours.
When these torrential downpours came, the ground and. earth took
twice as long to dry to worling conditions than if normal rainfall
had been received.
This has prompted this request for extending our contract
completion date to 11-12-93, which would add 32 days to the
existing contract total. Please call if additional information is
required and let us know if these days can be added so that we can
plan accordingly.
Respectfully,
/e dad/

ATTACHMENT D
Chronic Toxicity Testing Requirement
The permittee shall conduct chronic toxicity tests using
test procedures outlined in:
1. The North Carolina Ceriodaphnia chronic effluent
bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *February, 1987) or
subsequent versions.
The effluent concentration defined as treatment two in the
North Carolina procedure document is 97%. The permit holder
shall perform monthly monitoring using this procedure to
establish compliance with Special Order by Consent condition.
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
Special Order by Consent will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was
performed, using the appropriate 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
Post Office Box 27687
Raleigh, North Carolina 27611-7687
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 'must be
measured and reported if employed for disinfection of the
waste stream.
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 Order may be reopened and modified to
include alternate monitoring requirements.
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. Failure to submit suitable test results will
constitute a violation of Order conditions.

ATTACHMENT E
Chronic Toxicity Testing Requirement
The effluent discharge shall at no time exhibit chronic toxicity
in any two consecutive toxicity tests, using test procedures
outlined in:
1. The North Carolina Ceriodaphnia chronic effluent
bioassay procedure (North Carolina Chronic Bioassay
Procedure - Revised *February, 1987) or subsequent
version.
The effluent concentration at which there may be no observable
inhibition of reproduction or significant mortality is 97%
(defined as treatment two in the North Carolina procedure
document). The permit holder shall perform monthly monitoring
using this procedure to establish compliance with the permit
condition. 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
Post Office Box 27687
Raleigh, North Carolina 27611-7687
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 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 reopened and modified to include alternate
monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the
cited document, such a 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.

ATTACHMENT ,F
The Permittee shall conduct a test for priority pollutants
annually at the effluent from the treatment plant. The discharge
shall be evaluated as follows:
1. A pollutant analysis of the effluent must be completed
annually using EPA approved methods for the following
analytic fractions: (a) purgeables (i.e., volatile
organic compounds); (b) acid extractables; (c)
base/neutral extractables; (d) organochlorine
pesticides and PCB's (e) herbicides; and (f) metals and
other inorganics. The Annual Pollutant Analysis (APA)
Monitoring Requirement Reporting Form A, to be provided
to all discharges affected by this monitoring
requirement, describes the sampling and analysis
requirements and lists chemicals to be included in the
pollutant analysis. This monitoring requirement is to
be referred to as the "Annual Pollutant Analysis"
(APA).
2. Other significant levels of synthetic organic chemicals
must be identified and approximately quantified. For
the purpose of implementing this requirement, the
largest 10 GC/MS peaks in each organic chemical analytic
fraction (or fewer than 10, if less than 10
unidentified peaks) that occur for chemicals other than
those specified on the APA Monitoring Requirement
Reporting Form A should be identified and approximately
quantified as stated in the APA Reporting Form A
instructions. This part (item 2) of the APA monitoring
requirement is to be referred to as the "10. significant
peaks rule".
