AMENDMENT TO CONSENT ORDER 05.2375
The State of Florida Department of Environmental Protection ("Department") and the City
of Sanford ("Respondent") executed a Consent Order in OGC Case No. 05-2375 ("Original Order"),
on January 18,2006. This Amended Consent Order which amends the Original Consent Order is
entered into between the Department and the Respondent. It is hereby agreed between the parties
that this Amended Consent Order shall amend all of the provisions of the Original Order in its
entirety .
The Department fmds and the Respondent admits the following:
1. The Department is the administrative agency of the State of Florida having the power
.
and duty to protect Florida's air and water resources and to administer and enforce the provisions of
.'~ .
Chapter 403, Florida Statutes, and the rules promulgated thereunder, Title 62, Florida
Administrative Code. The Department has jurisdiction over the matters addressed in this Amended
Consent Order.
2. Respondent is a person within the meaning of Section 403.031 (5), Florida Statutes.
3. Respondent is the owner and is responsible for the operation of the SanfordINorth
WRF, a 7.3 MGD annual average daily flow (AADF) permitted capacity complete-mix activate
sludge wastewater treatment facility ("Facility") with a 1.0 MGD AADF permitted capacity
discharge (D-OO 1) of dechlorinated efiluent to the St. Johns River and chlorinated effluent to a 7.14
MGD AADF permitted capacity slow-rate land application system and a public access irrigation
reuse system. The Facility is located at 1201 West Seminole Boulevard, Seminole County, Sanford,
Florida, Latitude 280 48' 57" North and Longitude 810 16' 42" West.
4. The Department finds that the Respondent operates the Facility under Department
permit No. FL0020141, which expires on April 7, 2008. A file review conducted on August 22,
2005, attached as Exhibit 1, indicates that flow to the plant, wet weather flow, Total Nitrogen,
Carbonaceous Biochemical Oxygen Demand (CBODs), and Total Ammonia permit limits were
exceeded. In addition, on. August 9, 2005, a spill of approximately 100,000 gallons of partially
treated wastewater occurred at the Facility's reject pond. This overflow and exceedance of permit
limits are violations of Section 403.161(l)(b), Florida Statutes (lfF.S.If), and Rule 62-620.300(5),
Florida Administrative Code (ifF .A.C. If).
5. On September 13, 2005, the Department received a document from the Respondent
entitled If Abbreviated Water Quality Status Report" for the Facility, attached as Exhibit 2. This
document included the following:
a. Water Quality Issues at the SNWRF
I. Flow to the plant is exceeding the permitted limit.
2. Elevated concentrations and loadings of oil and grease and CBODs.
3. Periods when Nocardia is affecting the secondary treatment process.
4. Reject water recycled from the detention ponds has the potential to convey
algae and other microorganisms into the biological treatment system.
5. A new Pretreatment Ordinance was adopted in September 2004. This new
Ordinance provides a better system to control illegal discharges of oil, solids, CBOD, and other
pollutants of concern.
AMENDED

OGC File No. 05-2375B
6. Additional disinfection application points were added to the aeration basins,
RAS lines and detention pond return lines in an effort to control Nocardia and algae.
b. Class ill Water Quality Issues - SNWRF Wet Weather Discharges
I. The wet weather discharge flow is exceeding the permitted limit due to
extensive rainfall from the hurricanes, low reuse because of significant wet periods and rejection of
substandard efiluent.
2. Elevated concentrations of various Class III water quality criteria and
Nitrogen, on an occasional basis, during wet weather discharge to the St. Johns River.
3. An Actiflo pilot unit was utilized to evaluate the effect of the treatment unit
and various chemical coagulants and aids on reducing water quality characteristics of concern with
regard to surface water discharges and reclaimed water characteristics. Pilot testing showed
excellent results.
c. Water Quality Improvement Schedule
1. The City has completed a number of projects and has a number of on-going
projects to improve the utility infrastructure that will have a significant "positive" impact on the
operation of the Sanford Wastewater Management System such as: new influent structure, flow
metering system, odor control, grit removal, electrical controls, storage systems, digester tank
covers, a Class A biosolids management system, etc.
2. A consortium known as the "Tri-Party" is being formed to develop
reclaimed/augmentation water resources in the North Seminole County region to reduce
groundwater withdrawals associated with irrigation. A "high priority" project is the Mill Creek
Reclaimed Water Storage Pond. The development of recharge basins in the Tri-Party Service Area
was determined to be a very useful tool in mitigating the impact of groundwater withdrawals used
for potable water supply at area WTPs. A Tri-Party Agreement for the implementation of these
AMENDED
3 of 14
OGC File No. 05-2375B
infrastructure improvements is almost in place~ Upon completion of the Agreement, the engineering
design and permitting will proceed, with construction to proceed at a future date.
3. Phenol removal bench-scale studies began in August 2005 to evaluate
potential systems or chemical additions to remove phenolic compounds from the SNWRF wet
weather discharge to the St. Johns River. The most cost-effective and efficient alternative will be
selected to be incorporated with the ACTIFLO treatment process, which will be installed in FY's
2007 - 2008.
4. The two (2) new pretreatment employees will take a more active role in
reducing the discharge of pollutants of concern into the City's collection system.
5. Collection System Pollutant Discharge Surveys will begin in October 2005.
The purpose of the program will be to identify potential discharges of pollutants of concern and the
industries, establishments or individuals responsible for the discharges or whether the pollutant are
entering the system through infiltration and inflow.
d. InfiltrationlInflow (1/1) Improvements within the City's Wastewater Collection
System
1. Infiltration and inflow ("III"), in older portions of the collection system, are
causing lift stations overflows and increased wastewater flows to the Facility.
2. Excessive oil and grease concentrations are causing sewer overflows.
3. Outside contractors are causing damages to collection lines during
construction of road projects.
4. A number of lift stations have been rehabilitated and other lift stations have
"quick fix" lists for repairs that are being completed. The remainder of the repairs for lift stations
with "quick fix" lists are scheduled to be completed in fiscal year 2007. Some new lift stations and
collection systems will be built and some existing lift stations and collection systems will be
AMENDED
4 of 14
OGC File No. 05-2375B
abandoned. There are currently eleven (II) lift stations without SCADA systems. These lift stations
are scheduled to be retrofitted in fiscal year 2006.
5. The City of Sanford completed a Capacity, Management, Operation and
Maintenance (CMOM) Plan evaluation of the wastewater management collection system in 2004.
The City is maintaining the wastewater collection system as recommended and in accordance with
the CMOM Plan.
6. Existing GIS data must be evaluated and verified and new data collected as
required. Upon collection of all required data, a hydraulic model of the collection and transmission
system will be generated using a non-proprietary simulation package to evaluate the system, which
will allow identification of potential collection system problems and required infrastructure
improvements.
6. In a letter dated February 6, 2006, the Department revised Permit No. FL0020141 to
remove the requirements for monthly monitoring for Total Phenolic Compounds.
7. In a letter dated December I, 2006, the Respondent requested modifications of
Paragraphs 8 and 10 of the Original Order.
8. On January 22, 2007, the Department verified that the Respondent has installed
SCADA systems on all existing lift stations. All new SCADA units that are installed shall monitor
lift station flows, pressures and transmission main pressure immediately adjacent to the lift stations.
9. Having reached a resolution of the matter the Department and the Respondent
mutually agree and it is
ORDERED:
10. No later than June 30, 2006, Respondent shall c~mplete construction of and place in
service the improvements to the Chemical Application System - Secondary Clarification System.

anticipated delay has been or will be caused by circumstances beyond the reasonable control of
Respondent, the time for performance hereunder shall be extended for a period equal to the agreed
delay resulting from such circumstances. Such agreement shall adopt all reasonable measures
necessary to avoid or minimize delay. Failure of Respondent to comply with the notice
requirements of this Paragraph in a timely manner shall constitute a waiver of Respondenfs right to
request an extension of time for compliance with the requirements of this Amended Consent Order.
19. Persons who are not parties to this Amended Consent Order, but whose substantial
interests are affected by this Amended Consent Order, have a right, pursuant to Sections 120.569

this Notice. Persons whose substantial interests will be affected by any decision of the Department
with regard to the subject Amended Consent Order have the right to petition to become a party to
the proceeding. The petition must conform to the requirements specified above and be filed
(received) within 21 days of receipt of this notice in the Office of General Counsel at the above
address of the Department. Failure to petition within the allowed time frame constitutes a waiver of
any right such person has to request a hearing under Sections 120.569 and 120.57, Florida Statutes,
and to participate as a party to this proceeding. Any subsequent intervention will only be at the
approval of the presiding officer upon motion filed pursuant to Rule 28-106.205, Florida
Administrative Code.

AMENDED
10 of 14
OGe File No. 05-2375B
Mediation may only take place if the Department and all the parties to the proceeding agree
that mediation is appropriate. A person may pursue mediation by reaching a mediation agreement
with all parties to the proceeding (which include the Respondent, the Department, and any person
who has filed a timely and sufficient petition for a hearing) and by showing how the substantial
interests of each mediating party are affected by the Amended Consent Order. The agreement must
be filed in (received by) the Office of General Counsel of the Department at 3900 Commonwealth
Boulevard, MS #35, Tallahassee, Florida 32399-3000, within 10 days after the deadline as set forth
above for the filing of a petition.
The agreement to mediate must include the following:
(a) The names, addresses, and telephone numbers of any persons who may attend the
mediation;
(b) The name, address, and telephone number of the mediator selected by the parties, or a
provision for selecting a mediator within a specified time;
(c) The agreed allocation of the costs and fees associated with the mediation;
(d) The agreement of the parties on the confidentiality of discussions and documents
introduced during mediation;
(e) The date, time, and place of the first mediation session, or a deadline for holding the fIrst
session, if no mediator has yet been chosen;
(t) The name of each party's representative who shall have authority to settle or recommend
settlement; and

affected by the action or proposed action addressed in this notice of intent or a statement clearly
identifying the petition for hearing that each party has already filed, and incorporating it by
reference.
. (h) The signatures of all parties or their authorized representatives.
As provided in Section 120.573, Florida Statutes, the timely agreement of all parties to
mediate will toll the time limitations imposed by Sections 120.569 and 120.57, Florida Statutes, for
requesting and holding an administrative hearing. Unless otherwise agreed by the parties, the
mediation must be concluded within sixty days of the execution of the agreement. If mediation
results in settlement of the administrative dispute, the Department must enter a final order
incorporating the agreement of the parties. Persons whose substantial interests will be affected by
such a modified fmal decision of the Department have a right to petition for a hearing only in
accordance with the requirements for such petitions set forth above, and must therefore file their
petitions within 21 days of receipt of this notice. If mediation terminates without settlement of the
dispute, the Department shall notify all parties in writing that the administrative hearing processes
under Sections 120.569 and 120.57, Florida Statutes, remain available for disposition of the dispute,
and the notice will specify the deadlines that then will apply for challenging the agency action and
electing remedies under those two statutes.
20. Respondent shall allow all authorized representatives of the Department access to the
property and facility at reasonable times for the purpose sf determining compliance with the terms
of this Amended Consent Order and the rules and statutes of the Department.

Re: Sanford North Water Reclamation Facility (SNWRF)
Abbreviated Water Quality Status Report
Dear Ms. Ferraro:
The City of Sanford appreciates the District's assistance in resolving some of the water quality
issues occurring at the above referenced facility. Per your request at our meeting last month in
Sanford, this letter serves as a vehicle to address the City's on-going efforts to resolve various
utility system issues by issuing this "abbreviated" water quality status report for the SNWRF, to
include the following:
. Water quality issues at the SNWRF.
. Meeting the Class III Surface Water discharge limits, when discharging to the St. Johns
River via the wet weather discharge system.
. Minimize infiltration and inflow entering the wastewater collection system during heavy
rainfall events.
Each Item will be discussed with regards to the current condition, corrective actions being taken
by the City and the proposed "action- schedule. This will then be followed by a request for "Interim"
permit modification during the period where construction activities. pilot studies. etc. are being
conducted to resolve the system issues described herein.
Additional items addressed in the report include:
. A brief discussion of the current and proposed utility construction projects within the City
of Sanford Wastewater Management System Service Area.
. Additional proposed systems and programs associated with the Tri-Party Team (Sanford,
Lake Mary, Seminole County) that may be able to address additional reclaimed water
disposal options during periodS of wet weather.
"The Friendly City"
As always, the City is utilizing all potential resources to resolve these issues, meet all permit
requirements and produce an environmentally safe effiuent for beneficial use. As you know, our
collection system in parts of the City Is over 100 years old and is in need of some repair or
rehabilitation. Additionally, as growth is moving into the greater Sanford area, we are on the verge
of having to implement a new IWPP to ensure that commercial and light Industrial users are not
conveying significantly high concentrations of various constituents to the SNWRF or SSWRC that
could lead to problems In the treatment of the incoming substrate. A new Pretreatment Ordinance
has just been approved by the City Commission and is in the process of being implemented.
We hope that you find the infonnatton provided In this "abbreviated" water quality status report
gives you some Insight Into the efforts that the City and its Consultants are putting forth to resolve
our existing water quality issues as quickly as possible and that the methods or methodologies
selected are Illong-term" solutions, not "quick fixes.
If I can be of any further assistance, please do not hesitate to contact me at (407) 330-5640. We
look forward to working with the Department In the resolution of these issues and appreciate your
assistance, cooperation and coordination during this interim perloct
Sincerely,
CITY OF SANFORD

Rainfall received from the hurricanes in August and September 2004 totaled 34.91 inches
in a total of approximately 30 days. This caused the flows to the SNWRF to Increase
significantly which can be seen In the monthly ADF flows for August - October 2004. After
this period In time. the average monthly raw wastewater flow decreased to levels below the
currenUy permitted capacity of the SNWRF (7.30 MGD). In the period of June - July 2005,
another significantly wet period of approximately 30 days dropped another 22.96 inches
of rain In the focal area and the raw wastewater flows increased somewhat due to high
groundwater conditions; however, they are currently dropping back to norrnallevels.
With respect to water quality conditions at the SNWRF. the following observations have
been Identified:
1. Elevated concentrations and loadings of oil and grease and CBOD!.
2. There are periods when Nocardia is affecting the secondary treatment process.
3. Reject water recycled from the detention ponds has the potential to convey algae
and other microorganisms Into the biological treatment system.
The City of Sanford and its consultants have been taking a "proactive" approach to
identifying the cause of the problems and have been attempting to take "aggressive-
actions to correct these situations. The following actions have been proposed and
implemented with respect to the above issues:
1. Pretreatment Ordinance Modifications
a. A new Pretreatment Ordinance was adopted In September 2004. This new
ordinance provides a better system to control illegal discharges of oils and
greases, suspended solids, CBODs. and other pollutants of concem entering the
City of Sanford Wastewater Collection System.
b. Pretreatment Solutions. Inc. has been retained by the City for assistance in
implementing the "new. Pretreatment Ordinance and to conduct pollutant
discharge surveys throughout the service area.
c. Two (2) pretreatment positions were created by the City of Sanford to provide
enforcement of the "new" Pretreatment Ordinance. One position has been filled
and the employee is currently working and the other position will be filled within
the next thirty (30) days.

Rainfall received from the hurricanes In August and September 2004 totaled 34.91 Inches
in a total of approximately 30 days. This caused the seasonal discharge flows to the Sl
Johns River to increase slgniflcanUy as utility customers were not demanding reclaimed
water and Influent flows to the SNWRF were in an elevated condition due to the high
groundwater table. This is evident when one reviews the seasonal discharge flows for the
period from August - October 2004. After this period in time, the monthly seasonal
discharge flows to normal levels;. however, since the permit Is based on an annual average
basis, the MDF flow will not decrease significantly until the August - October 2004
seasonal flows are .cycled- out of the mathematical calculation. In addition, during the
. period of June - July 2005, another significantly wet period of approximately 30 days
dropped another 22.96 Inches of rain In the local area and the se~~~mal discharge flows
increased somewhat, again due to low demand for reclaimed water and elevated raw
wastewater flows entering the SNWRF.
With respect to seasonal discharge water quality conditions at the SNWRF, the fotrowing
observations have been identified:
1. Elevated concentrations of various Class III water Quality parameters, on an
occasional basis, during wet weather discharges to the St. Johns River.
2. Elevated Giardia and Cryptosporidlum counts.
3. Elevat.,d Total Nitrogen concentrations, on an occasional basis, during wet weather
discharges to the St. Johns River.
The City of Sanford has been taking a .proactive" approacb to identifying the cause of the
problems and have been attempting to take .aggressive. actions to correct these
situations. The following actions have been proposed and Implemented with resped to the

1. Bench-Scale Pilot Testing
a. The City has been conducting "bench-scale" pilot studies at the SNWRF since
2003. Various coagulants and coagulant aids (polymers) have been tested to
address wet weather discharge water quality Issues. when discharging to the St.
Johns River (Class III water).
b. Bench-scale testing results have indicated identified various coagulants and
coagulant aids that appear to be successful in meeting the objectives of the
study being conducted by the City's Water Resources Engineer.
c. Based on the results of the bench.scale studies, "full-scale" pilot studies were
conducted at the SNWRF to thoroughly test the above-referenced chemicals
that appeared promising in the ability to reduce various Class III water quality
parameters of concern in the SNWRF effluent.
2. Full-Scal~ Pilot T sstina
a. Aditio Pilot Testing
i. An Actiflo pilot unit (manufactured by KrOger, Inc.) was utilized for a three-
week period in November 2004 to evaluate the effect of the treatment unit,
and various chemical coagulants and aids, on reducing water quality
characteristics of concern with regard to surface water discharges and
reclaimed water characteristics. The water Quality characteristics evaluated
included all related Class 11/ surface water parameters, TSS, turbidity, true
color and Giardia and Crypto$porld;um.
iI. The following table presents analytical data from the ACTIFLO testing of the
effluent from the SNWRF. The test results Indicate that the chemical ACH
provided the best performance with regard to keeping the water quality
characteristics of concern below their MCL or required levels.

iii. "Full-Scale" pilot testing showed excellent results using the ACTIFLO
process. Chemical dosages and effluent water qual ity parameter excursions
were minimized by using the ACTIFLO process prior to tertiary filtration. Due
to the use of "ballasted-flocculation" In the ACTIFLO treatment scheme. the
required chemical dosages are about fifty percent (50%) of the typical
coagulation/flocculatlon chemical demand. This chemical savings, on a "Yull-
scale" basis, equates to approxImately $150,OOO/year.
iv. The City's consultant engineer. CPH Engineers, Inc., is currently performing
the preliminary engineering associated with the addition of two (2) 4.00 MGD
ACTIFLO units, process piping, sludge management modifications. yard
piping modifications, associated equipment,
electrical/controls/instrumentation, and SCAOA at the SNWRF. One (1)
ACTIFLO unit will be installed in each of the next two fiscal years.
b. Full-Scale Chemical Application Pilot Testing - SecondsI)' Clarification System
i. Full-scale chemical application pilot testing was conducted at the SNWRF,
using the coagulants and coagulant aids previously identified, during the
period from March 2004 to June 2004. The process chemicals were injected
into the influent flow to the secondary clarification system to assure that
enough reaction time was provided prior to discharge of the fluid into the
secondary clarification system, thereby enhancing the sedimentation of
solids and precipitation of water quality parameters of concern. The water
quality characteristics evaluated included all related Class 11/ surface water
parameters, TSS. turbidity, true color, phosphorus. nitrates. nitrates, Giardia
and Cryptosporidium.

(1) Test results indicate that all parameters of concern were found to be
below their method detection limit (MOL) with the exception of the copper,

(2) As was the case with the bench-scale studies, the chemical ACH
appeared to provide the best results with regard to ensurJng that all water
quality parameters were below the required Class III surface water limits.
(3) Effluent cyanide concentrations were below the Class III water quality
MeL 01 5 ugIL and were found to be below the MOL in three (3) of the
seven (7) sampling events conducted during the "fuU-scale- pilot testing
program.
(4) Nitrate, nitrite and phosphorous were reduced by all coagulants utilized
in the "full-scale- pilot testing program. As previously indicated. it
appears that the best results, with respect to these water quality
parameters, were produced through the use of the coagulant ACH.
(5) The only parameter not removed effectively to the Class III surface water
discharge limits. regardless of the coagulant or aid utifized In this series
of testing. was phenol. Therefore. the City is currently addressing the
phenol removal issue along two fronts:
(a) Conducting additional bench-scale pilot studies utilizing other
products/systems to investigate the best cost-effective treatment for
phenol removal.
(b) Collection system investigations to identify the source of the phenols
in the raw wastewater entering the SNWRF and the use of the
Pretreatment Program to control its discharge into said system.
(6) ~;ardia and CryptosDoridlum were not effectively removed by ACH, a
Harcross polymer, and/or A405 at low dosages. However, further
evaluations of the chemical coagulants Indicated that the use of the
Harcross polymer, at a dosage 4 mgIL, was found to effectlve~ remove
Giardia and CryJJto~poridium oocysts to the .proposed- compliance
levels. The City will be conducting additional Giardia and
Crypto~poridium "full-scale- pilot testing when the permanent ACTI FLO
unit is Installed and becomes operational.

WA8TEWATER COLLECTION SVaT..
The City of Sanford has one of the oldest water distribution and wastewater collection
systems in the State of Florida. Therefore, infrastructure Improvements in the older
portions of the systems is inevitable. The City's Utility Department annually budgets
approximately $500,000 to replace and/or repair water and sewer lines. The City also
created a .n~w" utility staff position (Water Resources Engineer) In an effort to evaluate the
City's needs regarding compliance with existing and forthcoming state and federal
environmental regulations. The Water Resources Engineer has been Integral in evaluating
the condition of the utility infrastructure and has perform a CMOM evaluation (2004) as well
as the Pilot Testing previously discussed at the SNWRF.
With respect to the wastewater management collection system, the following observations
have been identified:
1. Excessive oil and grease concentrations are causing sewer overflows.
2. Collection System staff are spen~lng a considerable amount of time cleaning
oil/grease from City's lift station to avoid potential overflows.
3. Outside contractors are causing damages to collection lines during construction of
road projects throughout the area as the population growth expands into the
Sanford area.
4. Infiltration and Inflow (III), In older portions of the collection system, are causing lift
stations overflows and increased WRF wastewater flows being conveyed to the
SNWRF due to the high groundwater levels associated with the hurricanes of 2004
. and the wet season that we are experiencing. .
The commissioning of the SSWRC will allow the City of Sanford to handle increased flows
being generated within the wastewater collection system from either growth or III.

iv. Construction of two "new" triplex lift stations (identical in configuration to the
"new" Fort Mellon Lift Station).
3. The Collection System Pollutant Discharge Surveys and the two "neW' pretreatment
employees will provide additional assistance in the monitoring and elimination of
significant discharges of oil and grease into the collection system. A key component
with regard to this issue Is to ensure that restaurants are pumping their grease traps
on a regular basis and not transferring these materials to the collection system and
treatment facilities whereby conveyance and treatment systems are significantly
impacted as well as effluent concentrations of pollutants of concern.
4. Capacity. Manaaement. Operation and Maintenance (C~9M) Plan
a. The City of Sanford completed a CMOM Plan evaluation of their wastewater
management collection system in 2004. The following elements were evaluated:
i. Proper management, operation and maintenance of the sewer colleetion
system.
ii. Sewer system capacity.
iii. Steps in place to mitigate the Impact of sanitary sewer overflows.

iv. A System Evaluation and Capacity Assurance Plan (SECAP) Is needed to
evaluate peak flow conditions.
c. QiI and Grease
i. It was determined that approximately eighty percent (80%) of th~ s_ani~!lry
sewer overflows within the Sanford Wastewater Management System
Service Area were caused by 011 and grease plugging of the system. The
number of sewer overflows has decreased since the "new" Ft. Mellonville Lift
station was constructed and with the implementation of the City's oil and
grease management program (2003).
ii. The City adopted a new Pretreatment Ordinance in September 2004
establishing fines a surcharges for non-compatible pollutants discharged Into
the City's wastewater management collection system. With the addition of
new pretreatment staff, It is anticipated that oil and grease program will take
two (2) to three (3) years to become "fully" and "globally" effective within th~_
service area.
5. Lift Station Maintenance Program
8. A City-wide SCADA system was installed In 1999 for the majority of the utility
system components within the City of Sanford Water and Wastewater
Management System Service Area. The major 11ft stations were retrofitted with
these systems. Since this time, the City has been Installing SCADA systems in
all of the remaining lift stations and all new lift stations are required to have
them. The SCADA systems provide the City with the ability to:
I. Monitor the lift stations performance.
ii. Monitor the forcemains.
III. Manage the "preventive" and "corrective. maintenance of the lift stations.
b. This collection of data assists the City with setting up and managing system
priorities, personnel and resources more effectively.

6. System Evaluation and CapacitY Assurance Plan (SECAP)
a. A System Evaluation and Capacity Assurance Plan (SECAP) for .the Sanford
Wastewater Management Collection System is needed, based on the results of
the CMOM analysis and Plan to evaluate peak flow conditions within the system.
The Plan will include flow evaluation during rainy days and a study of the
collection system hydraulics. The following task items and projects must be
completed before the SECAP can be performed and generated:
i. All of the City lift s'ations must have SCADA systems installed and the ability
to monitor lift station flows, pressures and transmission main pressure
Immediately adjacent to the lift stations.. There are currently eleven (11) lift
stations without SCADA systems. These lift stations are scheduled to be
retrofitted in fiscal year 2006.
ii. Existing GIS data must be evaluated and verified and new data collected as
required. Data shall include, but not be limited to, pipe size, pipe material,
lift station dimensions, pump capacity. horsepower and TDH (including pump
curves), etc.
b. Upon collection of all of the required data, a hydraulic model of the collection
and transmission system will be generated using a non-proprietary simulation
package (SewerCAD. etc.) to evaluate the system during wet and dry weather
conditions. The results of the computer simulation will allow the City to identify
potential collection system problems and required infrastructure improvements.
c. Schedule
i. The City will continue upgrading its GIS system, associated electronic
equipment, and utility computer software library to accelerate the collection
of data required to perform the SECAP. The process of system upgrading
began in 2003 and will continue into 2006. The "proposed" schedule is as

ii. An 1/1 study is scheduled to begin and be completed in Fiscal Year 2006.
The III study findings are to be scheduled for repairs in Fiscal Year 2007.
d. Utility funds will be budgeted every fiscal year to study areas that are know to
have high III inputs into the City's wastewater management collection system.
The results of said studies will lead to the generation of a capital improvements
program line item and future budgeting to correct the problem{s).
e. A number of overflows occurred during the hurricanes of 2004. One of the
hardest hit areas was the downtown service .area that connects into the vacuum
sewer collection system via nine (9) buffer tank connections. The City received
a mitigation grant thnJ FEMA to purchase fifty-three (53) stainless steel manhole
covers to minimIze stormwater inflow into the system at these sensitive sites.
f. The City of Sanford's Public Works Department will be implementing a "storm
drain cleaning program" in those.areas of the City where wastewater collection
system manholes were installed at a lower elevation than storm drains. This
condition leads to obstruction of storm drains, due to debris collection. thereby
causing a flooding of the roadway and a significant increase in the amount of
Inflow to the wastewater collection system through the pick holes in the manhole
covers.

2. Interim MCL of 47 uglL for phenolic compounds (Surface Water Discharge to Class
III W sters)
a. Water quality data from the pilot tests perfonned at the SNWRF Indicates that
phenolic compounds cannot be removed. to the levels required for discharge
into Class IIJ waters, by conventional treatment or through the use of the
coagulants/aids (those used in the pilot tests).
b. The City is proposing an interim MCL 47 ugIL for phenolic compounds in the wet
weather discharge to the St. Johns River until the two (2) ACTIFLO treatment
units are Installed. test, calibrated and become fully operatiQ!1al,... The City is
beginning to perform additional bench-scale pilottesting to additional chemicals,
measures and methodologies that can be used for the effective removal of
phenolic compounds.
c. The best technology for phenol removal, selected by the City, will be provided
to CPH Engineers. I nc. for their use and evaluation and to be incorporated with
the final design and construction of the ACTIFLO treatment units at the SNWRF.
The ACTIFLO installation will be fully complete. tested and operationally
functional, at full capacity, in Fiscal Year 2007.
d. The City is herein requesting that the interim MCL for phenolic compounds be
extended throughout Fiscal Year 2007.
3. A 2.0 MGD interim Wet Weather Discharge to the St. Johns River
a. The City of Sanford has a permitted seasonal discharge, to the St. Johns River,
during periods of wet weather. The annual average dally flow Is limited to 1.00
MGO by permit. A synopsis of the seasonal discharge water quality, for the
period between January 2004 and July 2005, was previously presented herein
and Indicates that this permitted flow limit has been exceeded.
b. Rainfall received from the hurricanes in August and September 2004 totaled
34.91 inches in a total of approximately 30 days. This caused the seasonal
discharge flQws to the St. Johns River to increase significantly as utility
customers. were not demanding reclaimed water and influent flows to the
SNWRF were in an elevated condition due to the high groundwater table. This
Is evident when one reviews the seasonal discharge flows for the period from
August - October 2004. After this period in time, the monthly seasonal
discharge flows to normal levels; however, since the permit Is based on an
annual'average basis, the MDF flow will not decrease significantly until the

August - October 2004 seasonal flows are "cycled" out of the mathematical
calculation. In addition, during the period of June - July 2005, another
significantly wet period of approximately 30 days dropped another 22.96 Inches
of rain in the local area and the seasonal discharge flows increased somewhat.
again due to low demand for reclaimed water and elevated rawwastewaterflows
entering the SNWRF.
c. As discussed previously, the City will be performing a SECAP and create a
hydraulic model to evaluate the wastewater collection system III problems. The
City Is also budgeting funds annual to study areas where III flows are
significant. Due to the time that Is required to perform collection system III
evaluations, Identify potential repairs or replacements, and budget constraints.
the City of Sanford is respectfully requesting an increase the of the permitted
Wet Weather Discharge to the St. Johns River, on an interim ba~is. to 2.0 M~D

frequency for the full-scale waste load allocation (WLA) analysis. The City
would propose a minimum testing and sampling period of at least one (1) year.
This would allow the generation of sufficient water quality data from surface
water discharges utilizing the ACTIFLO "advanced- treatment technology to
prove that the effluent would have no harmful effects to the receiving water and
could potentially provide a beneficial increase in current river water quality.
4. An interim 14.0 mg/L Annual AveraQe Nitroaen Limit
,
a. After evaluating operational records and the events leading to total nitrogen
violations in the wet weather discharges to the St. Johns River, it is clear that
many of the violations were caused by Nocardia blooms and related operational
problems during high rain events. Nocardia Is a filamentous bacteria that feeds
on animal fats, oil and grease. The City has been addressing this issue and
working to resolve the issues associated with an influx of Nocardia into the
biological treatment system, including, Qut not limited to, foaming issues, impad
on the beneficial microorganisms in the activated sludge process and poor
settling in the secondary clarification system. Nocardia outbreaks typically
occurs during cold/cool weather conditions In the fall or winter months.
However, due to the because of the hurricanes of 2004 and the excess flow
being received at the SNWRF due to elevated groundwater conditions this year,
the problem was extended through the spring and summer months.
b. A sample of the biological treatment system aeration basins was collected and
sent to Novozimes Biologicals for a microscopic evaluation of the biological ~
speciation within the biological reactors. As reported by Novozymes
Biologicals, the major microbial organism within the aeration basins was
determined to be Nocardia(bridging). The City requested a quotation from
Harcross Chemicals to treat the Nocardia infestation based on the results of the
analysis from Novozymes Biologicals. Unfortunately, the City will have to wait
until cold weather conditions this fall or winter to assess the need for this
treatment.
.c. Therefore, the City is requesting an interim increase In the limit for this
parameter until the following projects and studies are Completed:
i. The City is attempting to control the impact of the Nocardia by chlorinating
the RAS flow stream and the surface of the biological treatment system
aeration basins. This procedure began in July 2004 as well as the addition
of a polymer in January 2005. The seasonal discharge from the SNWRF,
with respect to total nitrogen concentrations, have not been exceeded the

permitted limit of 12 mgfL since the City started the combination of these two
chemicals. At the current time a nitrate meter is being installed in the
common effluent channel of the tertiary filtration system to monitor this
parameter and to make process changes as needed to control its
concentration. The City requests to complete a total of twelve (12) months
of monitoring ammonia, nitrate and total nitrogen to decide if these two
chemicals will keep the effluent product within the mandatory limits in the
long-term.
ii. The City Is in the process of conducting a "full-scale" pilot study of
Enviroquip's Symbio Process ,to promote simultaneous nitrification and
denitrification with the biological treatment systems' aeration basins. This
pilot study is expected to begin in November 2005, under the dIrect
supervision of Enviroquip and CPH Engineers, Inc.. and Is anticipated to
conclude In January 2006. If the test is successful, the system will be utilized
on a full-time basis for reduction of TN levels at the SNWRF.
m. The City will wait until cool weather conditions In FalllWinter 2005 to decide
if the Nocardia control with heavy dosages of chlorine in conjunction with
bioaugmentation is necessary to improve the SNWRF seasonal discharge
water quality and to minimize the potential of Nocardia blooms at the facility.
5. An interim CBODs monthly average limit of 35 moll and a maximum concentration
of 60 mg/L
a. The CBODs violations that occurred in January and February 2005 were related
to the lack of proper treatment due to a Nocardia bloom. This microbial issue
may be resolved once the ~9cardla is controlled primarily through control of its
food source (lactic products) or by chemical action. The City Is asking for a two
(2) year interim level, as indicated above, to collect and review data regarding
treatment improvements after the following process improvement are
implemented:
i. Oil/Grease Management Program
.
(1) The implementation ofthis program includes heavy fines and surcharges
for high strength discharges of CBODs and TSS by users within the.
wastewater management collection system. As previously indicated, the
City has hired an Environmental Coordinator as part of its Pretreatment
System expansion (September 2005).

(2) This staff member will be inspecting food related businesses to enforce
this new program and the discharge limitations. The use of fines and
surcharges for high strengths discharges are expected to impact these
business which will result in best management practices being
Implemented regarding the handling of oil, grease, CeODIS and TSS.
(3) The City has already "kick-started" this program by issuing collection
system surveys. to 238 of its commercial users (food related businesses)
in June 2005 to evaluate the discharges from said users. With the
addition of new pretreatment staff, It is anticipated that oil and grease
program will take two (2) to three (3) years to become "fully" and.
-globally" effective within the service area.
ii. Nocardia blooms at the SNWRF are controlled.
6. An interim weekly and monthly average Ammonia limit 7 maiL and maximum
concentration of 11 mQIL
a. Permit levels were exceeded due to NocardIa problems and it is expected to be
under control after the oiVgrease program Is Implemented and after the Nocardia
bloom are minimized by the methodologies described herein.
b. The City is respectfully requesting a two (2) year interim level for all three
ammonia compliance frequencies.

INTRODUCTION
The City of Santoro's Water Reclamation Facility (WRF) is loosted at 1201 West Seminole
Boulevard. It has a 7.3 mgd annual average daily ftow pennitted C8psclty and Is a complete mix
activated sludge domestic wastewater treatment plant consisting of flow equalization. Influent
screening, grit removal, aeration. secondary clalification, chemical feed, ftnration, chlorlnatfon,
followed bydechlortnation prior to surface water discharge, with sludge thickening, aerobic
digestion and dewatertngof residuals.
On March 29, 2005, the Florida Department of Environmental Protection (FOEp) mocflfied the
Domestic Wastewater Facility Permit # FLOO20141 for the City of SanfoRt's WRF to Include a
monthly monitoring requirement for all calendar months in which surface water discharge
occurred for beryllium, cadmium, copper. lead, selenium, silver, cyanide, total phenolic
compounds, pentaChlorophenol, 2,4,6 t"chlorophenol, total PoIycycnc Aromatic Hydrocarbons
(PAHs) and 2,4 dlnKrototuene.
On May 31, 2005. the Industrial Pretreatment sectiOn of the FDEP sent an assessment report for
the City of Sanford's Annual Report covertng the period from January 1, 2004 to December 31.
20~ which was submitted to the FDEP on time by May 1, 2005, The assessment noted that the
effluent priority pollutant scan perfonned on July 22, 2204 Indicated that poor removal efficiencies
had resulted In exceedSI1C85 of the Class III fresh water quality standards for cadmlLlll, lead and
mercury. The assessment alsO noted that total phenolic compounds, as measured by the 420.1
method, should be used as 8 screening tool rather than a compliance detennlnstlon with the
Class III fresh water quality standard of 1.0 ug/J. The effluent reported total phenolic compounds
concentration of 598 ugll however concerned the FDEP who is now requiring the City cI sanford
to identify Individual phenOlic and cresol spedes present in the wastewater.
A P'an of study to monitor for phenolic species using EPA Method 8270 to identify ,II phenolic
and cresol species together wlth other metallic pollutants of concern across the WRF at nine
different points on a totaf of three separate days was submitted to the FDEP on or before June
27, 2005. The following proposal sets out the procedures Intended to perform this sampling.

Grab sampling will begin at locations 1A. 1 B. 1 C and 1, Ontluent Sites) which will all be sampled
within 10 minutes of each other.
sampling wiD be performed at location 2 (Influent ftume) approximately 8 minutes later.
Sampling will be perfonned at location 2A (exit point from aeration tanks) approxtmately 5 hours
after locatlon 2.
Sampling will be performed at location 3 (Influent to filters) approximately e hours, 15 minutes
after locatlon 2A.
Sampling will be perfonned at location 4 (exit from Chlorfne Contact Chamber) approximately 46
minutes after localion 3.
Sampling will be performed at locatiOn 5 (inflow from pond) after all other sampling has been
completed.
The times quoted above are appUcable only to an influent flow of 7.3 MGD. The actual influent
ftow on the sampling days wi. be used to nx:omputed the sampling times using the volumes
shown In Table 1.
The WRF should be in good worldng condition with all processes functioning nonnally and within
engineering specifications at the time of all sampling procedures.
Discharge to the reject pond should not occur durfng the sampling procedure on any of the three
sampling days. Inflow from the pond will be sampled separately on each sampling day In
coordination wfth WRF operating personnel.
SAMPLING SCHEDULE AND COSTS
It is proposed to perfOITT1 the sampling on a SUNDAY, TUESDAY and THURSDAY of the same
week If possible. SampUng will begfn at 5:00 IN on the first day during low weekend ftow.
Sampling will begin at 5:00AM on the second day to represent weekday law flow conditions.
Slmpllng will begin 8112:00 midday on the third day to represent high flow contalnfng domestic
and industriaUcomrnercial ftOWl. sampUng wiD depend on low rainfall to keep Influent flows within
engineering speclftcations and plant processing capabilities Including the ability to cease flow
from the reject pond durtng the sampling period. The week of July 31 to August -4, 2005 is
targeted as the sampling week for this project. but this may change due to the above factors.
All simple bottles. preservation materials and field data sheets will be supplied by the contract
laboratory (TestAmer1ca) In adVance. The estimated costs are Itemized below.
