                                     Report to Congress on Combined Sewer Overflows to the Great Lakes Basin
                              Executive Summary
There are 184 combined sewer systems (CSS) in the Great Lakes Basin designed to collect and transmit
both wastewater and stormwater to a publicly owned treatment works (POTW) through a single network
of pipes. Wet weather events can cause combined sewer overflows (CSO) when the stormwater entering
the CS S exceeds the capacity of the collection system. CSO events can be detrimental to human health and
the environment because they introduce pathogens, bacteria and other pollutants to receiving waters,
causing beach closures, contaminating drinking water supplies, and impairing water quality. Fish and
other aquatic populations also can be impacted by the depleted oxygen levels that can be caused by CSOs.
This Report to Congress presents the U. S. Environmental Protection Agency's (EPA) most recent
assessment of the implementation status of CSO long-term control plans (LTCPs) in the Great Lakes
Basin, as well as a summary of existing data on the CSO discharge volume in the basin during calendar
year 2014.

Data Collection Methodology
EPA's methodology for data collection focused on obtaining existing data from federal and state sources.
Data were collected through a combination of direct data requests to the states and research of previously
published or available federal, state, and local government and nongovernmental agency sources. EPA
compiled an initial CSO inventory based on its in-house data and used the inventory to develop a data
collection template spreadsheet for each of the seven states that have CSO discharges in the Great Lakes
Basin. EPA sent the template spreadsheet to the seven states and then held a series of conference calls
with those states and their EPA regions to discuss how to update and complete the spreadsheet. Lastly,
EPA evaluated the returned state spreadsheets for consistency with the data collection instructions.

Statutory and Regulatory Requirements For CSOs
EPA issued a CSO Control Policy on April 19,1994 (59 FR18688, April 19,1994). The CSO Control Policy
"represents a comprehensive national strategy to ensure that municipalities, permitting authorities, water
quality standards authorities, and the public engage in a comprehensive and coordinated effort to achieve
cost-effective CS 0 controls that ultimately meet appropriate health and environmental obj ectives."
In the Consolidated Appropriations Act for Fiscal Year2OOi, P.L. 106-554, Congress amended the Clean
Water Act (CWA) to add Section 4O2(q), which provided that "...each permit, order, or decree issued
pursuant to this Act after the date of enactment of this subsection for a discharge from a municipal
combined storm and sanitary sewer shall conform to the CSO Control Policy signed by the
Administrator on April 11,1994."

Status of LTCPs in the Great Lakes Basin
LTCPs or other alternative CSO control plans are required for 183 of 184 (99 percent) of the CSO
communities located in seven states throughout the Great Lakes Basin (Table ES-i). These communities
have submitted 181 LTCPs or other alternative CSO control plans and 178 have been approved. New York,
Pennsylvania, Michigan, Illinois, and Wisconsin have all CSO communities in the Great Lakes Basin in
their state operating under approved LTCPs or other alternative CSO control plans. Ohio has received 52
LTCPs and has not received an LTCP from 2 CSO communities. Ohio has approved 50 of the 52 LTCPs it
has received. Indiana has received 26 LTCPs and has not received an LTCP from one CSO community.
Indiana has approved 25 of the 26 LTCPs it has received.

Similarly to Table ES-i, Table ES-2 presents the information about CSOsbut summarized by the Great
Lake to which they drain rather than by state.

CSOs in the Great Lakes Basin During 2014
The seven states reported 1,482 events where untreated wastewater was discharged from CSOs in the
Great Lakes Basin in 2014 (Table ES-i). Ohio reported 824 untreated CSO events; however, the state had
only partial data available on CSO events for five communities. Michigan reported 273 untreated CSO
events and New York reported 376 untreated CSO events. New York had no readily available data for
three communities.  Pennsylvania reported seven untreated CSO events, while Illinois and Wisconsin each
reported one untreated CSO event. Indiana did not have data readily available on the number of CSO
events for 20 of the 27 communities discharging CSOs into the Great Lakes Basin. Indiana reported no
overflow events for the 7 communities for which it reported.
The states reported an estimated volume of 22 billion gallons (BG) of untreated wastewater discharged
from CSOs into the Great Lakes Basin in 2014 (Table ES-i). However, Ohio had only partial data available
on CSO volume for eight communities and New York had no data available for five
communities. Michigan reported that CSOs in the state discharged a volume of 8.8 BG of untreated
wastewater, Indiana reported that CSOs in the state discharged a volume of 8. i BG of untreated
wastewater, Ohio reported that CSOs in the state discharged a volume of 3.2 BG of untreated wastewater
(Ohio had no available data on untreated CSOs from eight communities), New York reported that CSOs in
the state discharged a volume of 1.8 BG of untreated wastewater (New York had no available data for 5
CSO communities),  Illinois reported that CSOs in the state discharged a volume of 500 MG of untreated
wastewater, Wisconsin reported that CSOs in the state discharged a volume of 30,000 gallons of
untreated wastewater and Pennsylvania reported that CSOs in the state discharged a volume of 10,000
gallons of untreated wastewater.
The seven states reported 187 events where CSOs discharged treated wastewater in the Great Lakes Basin
in 2014 (Table ES-i). Ohio reported 27 treated CSO events; however, the state had only partial data
availableon CSO eventsfor five communities. Michigan reported i6otreated CSO events. New York,
Pennsylvania, Illinois, Indiana, and Wisconsin reported no treated CSO events in 2014. However, New
York did not have data readily available for three communities and Indiana did not have data readily
available for 20 of the 27 communities discharging CSOs into the Great Lakes Basin.
The states reported an estimated volume of 26 BG of wastewater that was treated with a minimum of
primary treatment (or its equivalent) and disinfected was discharged from CSOs into the Great Lakes
Basin in 2014 (Table ES-i). However, Ohio had no available data for five communities. Michigan reported
that CSOs in the state discharged a volume of 25 BG of treated wastewater, Ohio reported that CSOs in the
state discharged a volume of 400 MG of treated wastewater (Ohio had no available data on treated CSOs
from eight communities), and Indiana reported that CSOs in the state discharged a volume of 20 MG of
treated wastewater.
Table ES -2 presents the results discussed above by Great Lake. Figure ES -i depicts the volumes of treated
and untreated CS 0 volumes by state. Figure ES-2 depicts the same information by lake.

                                    Report to Congress on Combined Sewer Overflows to the Great Lakes Basin
                   1  Introduction and Background
   1.1 Why Is EPA Preparing this Report to Congress?

In the Consolidated and Further Continuing Appropriations Act, 2015, Congress directed the
U. S. Environmental Protection Agency (EPA) to provide available information on the status of the
Combined Sewer Overflow (CSO) Long Term Control Plans (LTCPs) for each CSO community in the Great
Lakes Basin. In addition, Congress requested a summary of the annual CSO discharge volumes in the
Basin during 2014. The Act provides:
   CSOs are a major contributor to water quality issues in the Lake Michigan Basin and it is noted that
   many communities have made strides to update wastewater infrastructure to mitigate the impact of
   CSOs. As such, the Agency is directed to provide a report based on available data indicating, for
   each CSOcommunity in the Great Lakes Basin, the implementation status of each CSOlong term
   controlplan. Additionally, the report should include a summary ofannualdischarge volumes.
EPA published three previous Reports to Congress that addressed CSO issues:

   •   Report to Congress—Implementation and Enforcement of the Combined Sewer Overflow
       Control Policy (EPA 2OOib), about progress made by EPA, states, and municipalities in
       implementing andenforcingthe CSO Control Policy.

   •   Report to Congress—Impacts and Control of CSOs and SSOs (EPA 2004), about the
       characteristics and impacts that CSOs have on receiving waters and human health and
       technologies used to control CSOs.

   •   Report to Congress—Combined Sewer Overflows to the Lake Michigan Basin (EPA 2007), about
       EPA's assessment of CSO events in the Lake Michigan Basin, the enforcement of existing
       regulations concerning such discharges, and the future steps EPA planned to take to minimize
       such overflows.

   1.2 The Challenges of Combined Sewer Systems and  Combined Sewer

         Overflows

There are two types of public wastewater collection systems in the United States: combined sewer systems
(CSS) andseparatesanitarysewers(SSS). CSSs were among the earliest sewer systems constructed in the
United States until the first part of the twentieth century. In contrast to SSSs, CSSs were specifically
designed to collect wastewater and stormwater in a single-pipe system to transmit the combined waters to
a publically owned treatment works (POTW) (see Figure 1-1).
Wet weather events (i.e., rain and snow events) can exceed the capacity of the CSS to convey
wastewater through the system and cause CSOs. During wet weather, most CSSs are designed to
discharge CSO flows directly to surface waters, including rivers, streams, estuaries, and coastal waters.
A CSO discharge is defined as "the discharge from a CSS at a point prior to the POTW treatment plant."
                                                                                  Page | 1

Figure l-l. Typical Combined Sewer System.

SomeCSO outfalls discharge infrequently, while others discharge every time it rains. Overflow frequency
and duration vary from system to system and from outfall to outfall within a single system. When
constructed, CSSs were commonly designed to handle between two and four times more than the average
dry weather flow (Moffa 1997). Thus, there is usually considerable conveyance capacity within a CSS
during dry weather. Consequently a CSS should not discharge during dry weather, but shouldconvey
flows to a treatment plant. One of the nine minimum controls (NMCs) of the CSO policy prohibits
discharges from a CSS during dry weather.
CSO discharges that occur as the result of wet weather can include wastewater from domestic,
commercial, and industrial sources as well as stormwater runoff. As a result, CSO discharges can contain
the waste from these sources as well as pollutants washed from streets, parking lots, and other surfaces.
CSO discharges vary greatly, both in terms of the specific pollutants in an individual CSO discharge and in
the concentrations of those pollutants in the discharge (EPA 2004). Pollutant concentrations in CSO
discharges depend on a number of factors, including the service population, the characteristics of theCSS,
weather conditions, and any treatment provided to the CSO prior to discharge.
CSO discharges can cause or contribute to water quality impairments and potentially expose people to
untreated sewage. Sewer overflows can also back up into residential homes, publicbuildings and
commercial facilities.
CSO discharges that occur as the result of a wet weather event are point source discharges subject to
National Pollutant Discharge Elimination System (NPDES) permit requirements including both
technology-based and water quality-based requirements of the CWA As of September 2015,859 active
NPDES permits for CSO discharges had been issued in 30 states plus the District of Columbia and Puerto
Rico. Of these 859 CSOs, 184 are located in the Great Lakes Basin. NPDES permits for CSO discharges are
issued to either:

   •  The operator of the wastewater treatment plant if the CS 0 outfall is owned and operated by the
       same entity as the treatment plant.

   •  The operator of a CS 0 outfall that operates a portion of a CS S that conveys flows to a wastewater
       treatment plant that is owned and operated by a separate entity.
                                                                                      Page | 2

                                       Report to Congress on Combined Sewer Overflows to the Great Lakes Basin
Most of the communities served by CSSs are located in the Northeast and Great Lakes regions, as shown
in Figure 1-2. Additional information on CSOs is provided in Report to Congress—Impacts and Control of
CSOs and SSOs (EPA 2004).

   1.3 What is the "Great Lakes Basin"?

The Great Lakes Basin is the connected watershed of lakes Erie, Huron, Michigan, Ontario (including the
St. Lawrence Seaway), and Superior. Together, the Great Lakes span both the United States and Canada
and drain an area of over 200,000 square miles (Table 1-1). The portion of the basin that lies in the
United States is approximately 111,548 square miles, exclusive of the St. Lawrence Seaway area
(Figure 1-3). As shown in the figure, the basin reaches into eight states (i.e., New York, Pennsylvania,
Ohio, Michigan, Indiana, Illinois, Wisconsin, and Minnesota1) and includes many major cities. The Great
Lakes Basin has relatively undeveloped portions in its northern reach, but is also home to major
metropolitan areas including Chicago, Illinois; Milwaukee, Wisconsin; Detroit, Michigan; Cleveland,
Ohio; and Buffalo, New York. I n total, more than 30 million people live within and impact the
environment of the Great Lakes Basin.
1 There are no CSO communities discharging to the Great Lakes Basin in Minnesota. The only remaining CSO
community in Minnesota is designed to discharge to the Mississippi River. Therefore, no results are provided for
Minnesota in this report.

The Great Lakes provide immeasurable value. They contain approximately 84 percent of the fresh surface
water in the United States. They provide sustenance and drinking water for millions of people, support
recreation and tourism, and provide transportation of materials and goods for industry. As many as 1.5
million jobs are supported by the Great Lakes, contributing to an estimated $62 billion in annual wages
(EPA 20153).

   1.4 How Do CSOs Impact the Great Lakes?

EPA has documented in earlier Reports to Congress that CSOs can cause human health and
environmental impacts (EPA2OOib, 2004). CSOs are one of many pollutant sources that impact the Great
Lakes. Other point sources include wastewater treatment facilities, stormwater discharges [e.g., from
municipal separate storm sewer systems (MS4s)], and concentrated animal feeding operations
(CAFOs). Nonpoint sources of pollution include agricultural runoff, atmospheric pollution, legacy
pollutants, and natural background sources. As shown in Figure 1-4, CSO communities are scattered
across the Great Lakes Basin, with the greatest concentration in Ohio, southeastern Michigan, and
northeastern Indiana discharging to Lake Erie, and in northern Indiana and southwestern Michigan
discharging to Lake Michigan.
                                                                                     Page | 5

CSOs often discharge simultaneously with other wet weather sources of water pollution, including
stormwater discharges from municipal separate storm sewer system (MS4s) and other sources, wet
weather sanitary sewer overflows (SSOs) from SSSs, and other nonpoint sources of pollution. The
combined effect of the wet weather pollution can make it difficult to identify and assign specific cause-
and-effect relationships between CSOs and observed water quality problems. The environmental impacts
of CSOsaremost apparent at the local level (EPA2OO4).

   1.5 The Federal Framework for CSO Control

The Clean Water Act (CWA) establishes national goals and requirements for maintaining and restoring
the nation's waters. CSO discharges are subject to the technology-based and water quality-based
requirements of the CWA. CSOs are not subject to limits based on secondary treatment requirements
applicable to POTWs. Technology-based effluent limits for CSO discharges are based on the application
of best available technology economically achievable (BAT) for toxic and nonconventional pollutants and
best conventional pollutant control technology (BCT) for conventional pollutants. BAT and BCT effluent
limits are determined based on "best professional judgment." Permits authorizing discharges from CSO
outfalls must include more stringent water quality-based requirements, when necessary, to meet water
quality standards (WQS).
                                                                                       Page | 6

                                     Report to Congress on Combined Sewer Overflows to the Great Lakes Basin


For more information about the development of the federal framework to address CSOs and CSO control
history see, Report to Congress—Implementation and Enforcement of the Combined Sewer Overflow
Control Policy (EPA 2OOib).

1.5.1 CSO Control Policy

EPA issued the CSO Control Policy on April 19,1994 (59 FR18688, April 19,1994). The CSO Control
Policy "represents a comprehensive national strategy to ensure that municipalities, permitting authorities,
WQS authorities, and the public engage in a comprehensive and coordinative effort to achieve cost-
effective CS 0 controls that ultimately meet appropriate health and environmental obj ectives." The policy
assigns primary responsibility for implementation and enforcement to NPDES authorities and water
quality standards authorities.
The policy also established objectives for CSO communities: i) to implement the NMCs and submit
documentation on NMC implementation; and 2) to develop and implement a long-term CSO control plan
(LTCP).
The policy provides that permittees with CSOs are responsible for developing and implementing an
LTCP that includes measures to ultimately result in compliance with the requirements of the CWA,
including water quality-based requirements. The policy identified the following nine minimum elements
that an LTCP should address:

    •   Characterization, monitoring, and modeling of the CSS;
    •   Public participation;
    •   Consideration of sensitive areas;
    •   Evaluation of alternatives;
    •   Cost/performance considerations;
    •   Operational plan;
    •   Maximization of treatment at the POTW treatment plant;
    •   Implementation schedule; and
    •   Post-construction compliance monitoring program.

The policy provides that at the discretion of the NPDES Authority, jurisdictions with populations under
75,000 may not need to complete each of the LTCP elements outlined above. In addition, the policy
provides that the NPD ES permitting authority may determine that some of the LTCP elements listed
above should not apply to certain permittees that had addressed their CS Os before the policy was issued.

1.5.2 Wet Weather Water Quality Act

In December 2000, as part of the Consolidated Appropriations Act for Fiscal Year 2001 (P.L. 106-554),
Congress amended the CWA by adding Section 4O2(q). This amendment is commonly referred to as the
"Wet Weather Water Quality Act of 2000." It requires that each permit, order, or decree issued
pursuant to the CWA after the date of enactment for a discharge from a municipal CSS shall conform to
the CSO Control Policy.

                                 2   Methodology
   2.1 Data Collection Method

The data collection supporting this report emphasized collecting readily available data from federal, state,
and local sources. Subsequent to the directive from Congress to develop this report, EPA conducted initial
discussions with the states by telephone and e-mail to get preliminary feedback on the types of data
relating to CSO communities that were available. EPA compiled an initial CSO inventory based on its in-
house data and used this inventory to develop and populate a data collection template for state
information. The collection template included three spreadsheets:

    •   The Data Collection Template spreadsheet, which included fields for all elements to be
       completed/updated by the states. In cases in which EPA had draft data from the states, draft data
       were included in the appropriate field, and states were asked to review and update them as
       necessary. In cases where no draft data were available, the fields were left blank and states were
       instructed to provide the information.
          o  In many cases, updates were made from prepopulated data choices accessible from drop-
              down menus [e.g., Yes, No, or Not Applicable (NA) options]. That approach helped
              ensure consistency of data between states. I n other cases, the state was able to enter
              information without restriction.

    •   The I nstructions spreadsheet contained specific instructions for each element to be completed on
       the Data Collection Template spreadsheet.

    •   The Definitions spreadsheet included definitions of key terms to help states complete the Data
       Collection Template spreadsheet. The definitions were intended to ensure that all states
       interpreted terms in a consistent manner and completed the data updates in a way that would be
       comparable across all states.
Data returned by the states were evaluated for consistency with the Data Collection Template spreadsheet
instructions. Because there is no specific guidance in the CSO Control Policy for CSO data collection,
reporting, or CSO volume quantification, information collected by the responsible agencies varies greatly
among states. Therefore, while the emphasis remained on collecting only readily available details (i.e.,
states were not requested to do additional collection or research to find requested data if they were not
immediately available), EPA reviewed the data the states returned to ensure they complied with the data
request—particularly with respect to the instructions and definitions included in the Data Collection
Template spreadsheet. EPA made requests for clarification to the states as necessary.

   2.2 What Data Were Collected?

Data collected included information on CSO permittees, their discharge locations, the status of LTCPs and
post-construction compliance monitoring programs, historical and anticipated future CSOs, and 2014
CSOs. The various data collected are summarized in Tables 2-1 through 2-4.
                                                                                      Page | 9

   3.1 Distribution of CSO Communities

The Great Lakes Basin in the United States includes 184 CSO communities in seven states (New York,
Pennsylvania, Ohio, Michigan, Indiana, Illinois and Wisconsin).2 As shown in both Figure 3-1 and Table
3-1, Ohio has the most CSO communities in the Great Lakes basin (54), while Pennsylvania has the least
(i). Only 4 percent (8 out of 184) of CSO communities in the Great Lakes Basin discharge directly into the
Great Lakes; most discharge to a stream or river that eventually discharges to a Great Lake.
                                                                            Great Lakes CSO

Most of thelarger CSO communities in the Great Lakes Basin in the U.S. discharge to Lake Erie and Lake
Michigan. For example, Detroit, Cleveland, Buffalo, Toledo, Akron, and Erie discharge to Lake Erie; and
Chicago,3 Milwaukee, South Bend, Grand Rapids, and Lansing discharge to Lake Michigan.

   3.2 LTCP Status of CSO Communities

As shown in Table 3-3, the vast majority of CSO communities in each Great Lakes Basin state required to
submit an LTCP or other alternative CSO control plan are operating under approved plans. New York,
Pennsylvania, Michigan, Illinois, and Wisconsin have all CSO communities in the Great Lakes Basin in
their state operating under approved LTCPs or other alternative CSO control plans.

The status of LTCPs and other alternative CSO control plans by lake is shown in Table 3-4. Similar to the
analysis of LTCP and other alternative CSO control plan status by state, the vast majority of CSO
communities draining to each lake operate under approved LTCPs or other alternative CSO control plans.
Lake Ontario/St. Lawrence Seaway, Lake Huron and Lake Superior have 100 percent of their CSO
communities operating under approved LTCPs or other alternative CSO control plans.
 Chicago is part of the TARP system, where CSOs are designed to discharge to the Illinois River system. Discharges
occur to Lake Michigan only under extreme weather conditions.

   3.3 Post-Construction Compliance Monitoring Program  Status of CSO

          Communities

The states that had available data on post-construction compliance monitoring plans indicated they are
requiring 153 out of 183 (84 percent) of U.S. CSO communities in the Great Lakes Basin to submit post-
construction compliance monitoring plans (Table 3-5). The majority of the communities in the Great
Lakes Basin that are not required to submit post-construction compliance monitoring plans are in
Michigan (26). New York (3) and Ohio (i) also indicated they are not requiring some CSO communities to
submit post-construction compliance monitoring plans. Pennsylvania had no available data on post-
construction compliance monitoring plans.
The majority of required post-construction compliance monitoring plans have been submitted in
Wisconsin, Indiana, Michigan, and New York. Michigan and Wisconsin have received 100 percent,
Indiana 93 percent, and New York 80 percent of their required plans. Ohio reported receiving 91 percent
post-construction compliance monitoring plans for which they have available data; however, Ohio had no
available data on the submission of 42 required post-construction compliance monitoring plans. In
addition, as described above, Ohio has one community that does not require a post-construction
compliance monitoring plan. Illinois has received 32 percent of their required plans.
Sixty-three of the 78 post-construction compliance monitoring plans (81 percent) that have been received
have been approved by the states. Ohio, Michigan, Indiana, and Wisconsin haveapproved 100 percent of
the post-construction compliance monitoring plans they have received, and New York has approved 75
percent of the plans it has received. No post-construction compliance monitoring plans have been
approved in Illinois.
                                                                                     Page | 16

The states require post-construction compliance monitoring plans for most of the CSO communities
discharging into lakes Ontario, Erie, and Michigan. However, states have not required the majority of
communities with CSOs discharging to lakes Huron and Superior to submit post-construction compliance
monitoring plans (Table 3-6). With respect to submission and approval of post-construction compliance
monitoring plans, of those communities for which the states had available data, Lake Huron and Lake
Superior had 100 percent of their required post-construction compliance monitoring plans approved.
LakeOntario/St. Lawrence Sea way had five of eight required plans approved (63 percent), while Lake
Erie had 34 of 78 required plans approved (44 percent) and Lake Michigan had 21 of 64 required plans
approved (33 percent).

   3.4 Treated and Untreated CSOs

Treatment is provided for some CSOs prior to discharge.  Other CSO outfalls discharge untreated
wastewater and stormwater. This Report distinguishes between treated CSO discharges and untreated
CSO discharges. For the purposes of this Report, "treated CSO discharges" refers to those discharges that
receive a minimum level of treatment as described in the 1994 CSO Control Policy FR18688,18693:

    •   Primary clarification (Removal of floatables and settleable solids may be achieved by any
       combination of treatment technologies or methods that are shown to be equivalent to primary
       clarification.);

    •   Solids and floatables disposal; and

    •   Disinfection of effluent, if necessary, to meet WQS, protect designated uses and protect human
       health, including removal of harmful disinfection chemical residuals, where necessary.

"Untreated CSO discharges" refers to those that either receive no treatment or less treatment than
described above.

   3.5 Untreated CSO  Events  in 2014

The states reported 1,482 untreated CSO events in the Great Lakes Basin in 2014 (Table 3-7). The states
reported the following numbers of CSO events:

    •   Ohio—824 untreated CSO events. NotethatOhiohadonlypartialdataavailableforfive
       communities;
    •   New York—376 untreated CSO events. Note that New York had no data available for three
       communities;
    •   Michigan—273 untreated CSO events;
                                                                                     Page | 18

Basin and only one event in 2014 was to Lake Michigan.
A tabulation of reported untreated CSO events in 2014 by Great Lake is presented in Table 3-8. A total of
1,334 untreated CSO events were reported for Lake Erie in 2014, which was the most by far for any of the
Great Lakes. Lake Ontario/St. Lawrence Seaway had the second most events (74 untreated CSO events),
followed by Lake Michigan (73 untreated CSO events) and Lake Huron (one untreated CSO event). The
states reported no untreated CSO events occurred in the Lake Superior basin.

   3.9 Summary of Individual State Data

3.9.1 New York
New York has 13 communities with CSO discharges in the Great Lakes Basin, including 10 that discharge
to LakeOntario/St. Lawrence Seaway and three that discharge to Lake Erie (Figure 3-2 and Appendix
Table A-i). New York's CSO communities in the Great Lakes Basin are primarily small, with the exception
of Buffalo, which discharges into waterbodies leading to Lake Erie; and Rochester, which discharges into
waterbodies leading to Lake Ontario. Most CSO communities in New York do not discharge directly into
the Great Lakes, although Dunkirk discharges directly into Lake Erie.

Figure 3-2. CSO Communities in the Great Lakes Basin in New York.

All CSO communities in New York require LTCPs, and LTCPs for all of these communities have been
submitted and approved (AppendixTable A-2). Post-construction compliance monitoring plans are
required for all CSO communities except Rochester, Medina, and Gouverneur (AppendixTable A-3). Post-
construction compliance monitoring plans have been submitted for eight out of the 10 communities where
they are required and approved in six.
New York reported 376 untreated CSO events in 2014, consisting of 1,800 MG of combined sewage

Niagara Falls. In addition, no CSO volume data was readily available for Clayton Village, Ogdensburg, the
Frank E. VanLare STP in Rochester, Lockport, or Niagara Falls. The number of CSO events and volume of
combined sewage discharge are estimates based mostly on local modeling the overflows using a baseline
annual precipitation. They are not actual measured quantities.

3.9.2 Pennsylvania

The City of Erie, located in northwestern Pennsylvania on Lake Erie, is the only CSO community in
Pennsylvania that is in the Great Lakes Basin (Figure 3-3 and Appendix Table A-6). The city's CSOs
include direct discharges into Lake Erie. The city's LTCP was approved in 2001 (Appendix Table A-y), but
no data was available regarding its post-construction compliance monitoring program (Appendix Table A-
8). Erie reported seven untreated CSO events in 2014, which discharged 0.12 MG of untreated combined
sewage into Lake Erie (Appendix Table A-io).4

 The City of Erie used the presumption approach in its LTCP (with an 85 percent capture WQBEL); however, the
city has documented as of its 2014 Annual Report that it is capturing more than 99 percent of its CSO volume.

3.9.3 Ohio

The 54 CSO communities in the Great Lakes Basin in Ohio all discharge to Lake Erie (Figure 3-4). The
communities range from very large systems [e.g., Northeast Ohio Regional Sewer District (NEORSD)
around Cleveland] to very small systems (several communities, including Hamler and Metamora, serve
populations of fewer than 1,000). Avon, Euclid, Lakewood, and NEORSD discharge directly into Lake
Erie, while the remainder of the communities discharge to other receiving waters that eventually drain to
Lake Erie (see Appendix Table A-n for a list of individual communities).

Figure 3-4. CSO Communities in the Great Lakes Basin in Ohio.

A total of 52 of the 54 communities in the Great Lakes Basin in Ohio required LTCPs or alternative CSO
control plans (Table 3-3 and Appendix Table A-12).5 Two communities did not require LTCPs or
alternative CSO control plans:

    •   Wauseon submitted an LTCP to the state of Ohio, although the city's NPDES permit did not
       require it.

    •   Willard achieved compliance with the CSO Control Policy without needing an LTCP.
 Luckey's NPDES permit required submission of a sewer separation plan as an alternative CSO control plan rather
than an LTCP.
                                                                                    Page | 27

                                     Report to Congress on Combined Sewer Overflows to the Great Lakes Basin


Fifty-one of the 52 communities required to submit LTCPs or alternative CSO control plans have done so;
Elyria is the exception (Appendix Table A-12). With the exception of Bucyrus and Lakewood, all of the
LTCPs or alternative CSO control plans that have been submitted have been approved.
Fifty-three of 54 communities had a requirement to develop a post-construction compliance monitoring
plan (Appendix Table A-is). Willard was the exception. Ten communities have submitted post-
construction compliance monitoring plans that have been approved.
Thirty-two Ohio communities reported CSO events in 2014 (five communities did not have complete
available data on CSO events in 2014) (Appendix Table A-IS). They ranged from a high of 107 CSO events
in Lakewood to single events in Bowling Green and Paulding. Almost all reported CSO events were
untreated. However, NEORSD reported 27 treated CSO events resulting in 435 MG of discharge, but had
no available data on untreated CSO events. The total reported volume of CSO discharges in in Ohio in
2014 was approximately 3,200 MG of untreated combined sewage and 440 MG of treated combined
sewage. Akron and Fremont reported the highest volume of untreated combined sewage, at over 800 MG
each. This was more than double the next highest reported volume, which was approximately 300 MG by
the City of Toledo.

3.9.4  Michigan

There are46 communities discharging CS Os to the Great Lakes in Michigan (Figure 3-5 andAppendix
Table A-i6). They include 18 CSO communities in the Detroit Water and Sewerage Department (DWSD)
service area, as well as medium-sized cities like Grand Rapids and Lansing. There are also much smaller
communities, like Croswell and Crystal Falls, which have populations under 3,000 people. CSO
communities in Michigan discharge to four out of the five Great Lakes: 27 to Lake Erie (including the
Detroit area CSOs), six to Lake Huron, 11 to Lake Michigan (including Grand Rapids and Lansing), and
two to Lake Superior. There are no CSOs discharging directly to the Great Lakes in Michigan; all CSOs
discharge to a river, stream, or other water body leading to a Great Lake.
                                                                                    Page | 28

monitoring plans. Twenty-six communities do not require post-construction compliance monitoring plans
(Appendix Table A-i8).
Thirty-two of the 46 communities reported CSO events in 2014 (Appendix Table A-2O). The number of
events per community ranged from one to 60 (treated plus untreated events). The largest CSO volumes

3.9.5 Indiana

There are 27 CSO communities in the Great Lakes Basin in Indiana (Figure 3-6 and Appendix Table A-2i).
Nine of these communities (primarily in the northeastern part of the state) have CSOsthat discharge to a
water body that eventually discharges to Lake Erie, while the remaining 18 (mostly in the northwestern
part of the state) have CSOs that discharge to a water body that eventually discharges to Lake Michigan.
Most of the communities are relatively small, with only Gary, South Bend, Hammond, and Fort Wayne
having substantial populations. There are no CSOs discharging directly to the Great Lakes in Indiana; all
CSOs discharge to a river, stream, or other water body leading to a Great Lake.

Figure 3-6. CSO Communities in the Great Lakes Basin in Indiana.

All 27 Indiana CSO communities in the Great Lakes Basin require LTCPs except Kendalville, which has
completed an alternative control plan (Appendix Table A-22). All communities have submitted their
LTCPs except for Gary, and all have had their plans accepted except for Gary and Hammond. A similar
pattern occurs with post-construction compliance monitoring plans. All communities have submitted and
had their plans approved except Gary and Hammond, which have yet to submit plans (Appendix
TableA-23).

Indiana did not have data readily available on the number of CSO events in 2014 for a large majority of
CSO communities (Appendix Table A-25). However, the state did have data available on CSO volume. All
communities reported untreated CSO overflows in 2014 except the seven communities that had
                                                                                   Page | 30

completely separated their sewers, with untreated CSO volumes ranging from under i MG (in Angola,
Auburn, Kendalville, and Ligonier) to over 1,000 MG (in Fort Wayne, Gary, and Hammond). Butler,
Goshen, Valparaiso, and Waterloo also reported some treated CSO discharges, with volumes ranging from
less than i MG to 14 MG.

3.9.6 Illinois

All CSO communities in the Great Lakes Basin in Illinois are in the Chicago metropolitan area (Figure 3-7
and Appendix Table A-26) and part of the TARP. TARP was approved as the LTCP for the Metropolitan
Water Reclamation District of Greater Chicago (MWRDGC), the City of Chicago, and 40 satellite
communities. TARP provides a good example of an LTCP with CSO remedial control measures that, upon
completion, are expected to address CSOs containing untreated sewage in Chicago area waterways that
occur during flood and wet weather events. TARP is the subject of a Federal Judicial Consent Decree that
was upheld in July 2015 by the Seventh Circuit Court of Appeals. Under the Consent Decree, MWRDGC
will complete implementation of TARP to eliminate a substantial percentage of CSOs by December 31,
2029, that, upon completion, is estimated will cost more than $3 billion. This plan includes the
construction of 109 miles of tunnels that will have a storage capacity of approximately 2.3 billion gallons
and the completion of three reservoirs. The tunnel and reservoirs will have a combined capacity of
approximately 17 billion gallons of sewage and flood water.
MWRDGC is required under the CSO Decree to implement a green infrastructure program. Under that
program, where feasible, MWRDGC will prioritize green infrastructure projects where they (i) will help
reduce flooding and basement backups; (2) can be readily accommodated as permanent stormwater
control measures on vacant parcels that can be retrofitted into "stormwater parks" that would store and
infiltrate or reuse rainfall and runoff, and be an amenity for local residents; and (3) can improve
socioeconomic conditions in the MWRDGC service area where the need is greatest, specifically by
improving conditions in areas impacted by environmental justice concerns.

Illinois reported 41 CSO events from TARP in 2014 (becauseTARP is an integrated system, this means
that on 41 occasions in 2014, at least one of the CSO points in the TARP interceptors discharged combined
sewageto the local waterway (Appendix Table A-so). However, only one of the events discharged to Lake
Michigan; the other 40 discharged to Chicago-area rivers draining away from Lake Michigan. The one
discharge event to Lake Michigan in 2014 resulted in a discharge of 525 MG of untreated CSO into the
lake.

3.9.7 Wisconsin

Wisconsin has two CSO communities that discharge to the Great Lakes Basin (Appendix Table A-3i).
Milwaukee's Metropolitan Sewerage District (MMSD) discharges to Lake Michigan and the community of
Superior discharges to Lake Superior (Figure 3-8). MMSD is a large system that serves 26 communities,
including the City of Milwaukee; Superior is smaller. The MMSD permit includes discharges to
waterbodies leading to Lake Michigan and two discharges into Milwaukee's Outer Harbor on Lake
Michigan. Similarly, the City of Superior has direct discharges to Superior Bay and St. Louis Bay on Lake
Superior, aswell as to waterbodies leading to the lake.

approved in 2007, while Superior's was approved in 2013. Both communities also have approved post-
construction compliance monitoring plans (AppendixTable A-33). MMSD's plan was approved at the
sametime as its LTCP in 2007, while Superior's was approved in 2015.
MMSD reported one untreated CSO event in 2014, with an untreated CSO volume of 0.3 MG (Appendix
Table A-35). Superior reported no CSO overflow events and no CSO overflow volume in 2014.

1 Hearing completion of separation and storage projects.
2 Currently collecting flow and rain fall data to conduct an evaluation study (Submitted) and model collection system for each of the 5 retention/treatment basins
b determine whether adequate presumptive treatment is provided for the discharges; improvements to the retention/treatment basins may be required in the
future pending the results of the evaluation studies. The study will evaluate basin 4 as a representative of basins 1 thru 4, and basin 5 separately.
3 Long-term Control Program being implemented; retention/treatment basin (RTB) construction complete and facility is "on-line"; no remaining untreated
overflow outfalls; RTB has been shown to provide treatment that meets criteria for elimination of raw sewage S protection of public health, protection of
dissolved oxygen standard, protection of physical characteristic standard, and no significant impact on downstream biological communities. The permit
required "Total Residual Chlorine Mixing Zone/Plume Definition Study" has been submitted and reviewed and it has been determined that TRC in discharges
does not cause violations of water quality standards. Therefore dechiorinafon is not required.
4 Long-term Control Program being implemented; retention/treatment basin (RTB) construction complete and facility is "on-line"; no remaining untreated
overflow outfalls; RTB has been shown to provide treatment that meets criteria for elimination of raw sewage S protection of public health, protection of
dissolved oxygen standard, protection of physical characteristic standard, and no significant impact on downstream biological communities. The permit
required "Total Residual Chlorine Mixing Zone/Plume Definition Study;" has been submitted and is currently under review by the Department. The report
evaluates whether or not the Total Residual Chlorine (TRC) discharges from the RTB cause violations of water quality standards.
6 Long-term Control Program has been completed; program & permit required 3-phase sewer construction project designed to reduce wet-weather flow
quantities directed to the retention/treatment basin (RTB); permit also required submittal of RTB Evaluation Study to determine whether adequate treatment is
provided to meet water quality standards (the results of the study were ultimately approved on Jan. 31, 2007); the actual construction phase of the current
project is complete; there are no "uncontrolled" (i.e., untreated) CSO outfalls associated with this permittee/program. An "In-Stream Total Residual Chlorine
(TRC) Effluent Plume Evaluation" is required by the permit (October 1, 2012) and shall identify the location and size of the TRC effluent plume during and
after CSO discharge events and identify the maximum TRC concentrations instream at various downstream locations.
6 Mostly separated, retention basin and overflow pond constructed to retain excess wet weather flow.

  Separation  complete.
  Long-term Control Program being implemented; the Department reissued a permit  that recognizes a modified LTCP. The permittee  submitted  a revised basis
  of design report in late 2009 followed  by a f nancial  capability assessment.  The City requested a modified  LTCP (and NPDES permit),  to extend the
  construction  schedule due to economic  hardship. The modified  LTCP will  1) correct existing construction issues with some shafts by using sewer separation
  and/or reconfigured use of shafts,  and 2) revise some of the additional shaft projects to sewer separation projects. The Department  approved the City's
  request and  issued a  schedule in the  modified  permit requiring elimination  of all overflow outfalls by December 31, 2025; several outfalls and the associated
  overflows have already been eliminated.	
  Final outfall re-routed to Wayne Co Dearborn Heights RTB.
 ' Long-term Control Program being implemented; controls include retention/treatment basins (6 online), CSO Screening/Disinfection  Facilities  (3 online), and
  13 in-system storage dams in the collection system sewers (online) for temporary storing and subsequent transport of combined flow to the wastewater
  treatment plant; expansion of primary treatment capacity attheWWTP to 1700 MGD (online). To date,  14 CSOs have been eliminated, and construction of
  the Oakwood RTB has been completed. In addition to these 14 outfalls,  5 untreated Rouge River CSOs downstream  of the turning basin are now controlled.
  An amended LTCP was submitted in late 2008 that proposed control projects and associated schedules for 3 untreated CSOs to the Old Channel of the
  Rouge River, and the 39 remaining untreated CSOs to the Detroit River. However, in 2009, due to  its deteriorating  financial condition, Detroit terminated
  construction  of (he Upper RougeCSO Capture Tunnel (URT). A f nancial capability assessment  (FCA)  was submitted  and approved by the Department. The
  alternative LTCP was included in the 2011 permit modification.  Another FCA was submitted  by Detroit in 2012 as required by the Permit. The FCA again
  documented  that costs associated with continued implementation of the CSO correction program were  a high burden to the City of Detroit  residents.
  Reflecting  the 2012 FCA and updated  costs for effectively  operating the WWTP and other facilities,  and taking into  account opportunities to use Green
  Infrastructure and apply adaptive management, the permit again revised the LTCP. Remaining high-priority outfalls  are due corrected by 2037. Note  that the
  adaptive approach was acceptable to EPA because  of the high level of treatment  (95%) by 2019 upon completion of disinfection  of all excess flow  at the
  VWVTP.
 1 Long-term Control Program complete; controls included both sewer separation and construction of a retention treatment  basin (RTB) and tunnel.
 - Presumptive basin construction  complete.  An "In-Stream Total Residual Chlorine (TRC) Effluent Plume Evaluation"  is required by the permit (October
  2018) and shall  identify the location and size of the TRC effluent  plume during and after CSO discharge events and identify  the maximum TRC
  concentrations  in-stream  at various downstream  locations.
 ' Long-term Control Program being implemented; controls include 30-MG Market Ave. Retention  Treatment Basin in conjunction  with sewer separation
  construction; permittee has completed  sewer separation projects; permit is in the process of being  revised to include  a schedule for a system project
  performance certification.	
 ' Outfall  011  scheduled to be eliminated  by 12/30/22.
 > Long-term Control Program considered complete (an existing retention/treatment basin); permittee submitted  2008 report characterizing  discharges from
  existing  retention/treatment basin based upon the type of sewer collection system (i.e., separate or combined) leading to this CSO treatment facility  adjacent
  b the municipal  wastewater treatment  plant. Facility is implementing revisions to disinfection feed system and conducting  visual assessments  of CSO
  discharges to evaluate screening effectiveness.	
 1 Long-term Control Program (sewer separation  project) being implemented;  separation construction is to be conducted in 6 phases; Phases I, II, III and IV
  have been completed;  permit schedule requires completion of construction  of sewer separation phases and elimination  of overflows by 2019.
 ' Long-term Control Program (sewer separation  project) being implemented;  permit requires elimination  of overflows from Outfall 018 by Dec. 31, 2016.
 1 Long-term Control Program being implemented; permit requires elimination of discharges from the one remaining outfall  by Jan. 1, 2020. Facility is one
  construction  project away from elimination  of the last CSO.	
 1 Long-term Control Program being implemented; existing  retention/treatment  basin was upgraded in mid-1990s; reissued permit required an "Instream
  Dissolved Oxygen Study" to determine whether discharges from the facility cause violations of water quality standards and if additional  corrections might be
  necessary;  there are no uncontrolled (i.e., untreated)  CSO outfalls associated with this permittee/program.	
 ' Long-term Control Program has been implemented;  controls included partial sewer separation & in-system storage tunnel in conjunction w/exisfng
  retention/treatment  basin; construction  phase of the project is complete  and all discharges have been re-directed to the storage tunnel; and the permittee has
  certified  the project; there are no remaining "uncontrolled" (i.e., untreated) CSO outfalls associated with this permittee/program.	
 1 Separation  and basin construction  complete; sewer lining and manhole rehabilitation planned.
 - Long-term Control Program being implemented; too existing clarifers with disinfection  and dechlorinafon; additional work is being conducted
  (infiltration/inflow  reduction) to increase transport capacity to the wastewater treatment plant;  permit requires submittal  of Evaluation Study to confirm whether
  adequate treatment is provided.	
 1 RTB construction complete.

24 Long-term Control Program has been completed; permit S program required construction project to upgrade the George W. Kuhn (formerly "12 Towns")
  Retention Treatment Facility to ensure that fealty provides adequate  presumptive treatment of discharges; upgrades included capacity /volume increase and
  disinfection  improvements; construction  offecilty upgrades was completed on Dec. 22, 2005; presumptive basin;  there are no "uncontrolled"  (i.e., untreated)
  CSO outfalls associated with this permittee/program.	
26 Long-term Control Program (sewer separation  project) being implemented;  Director's Final Order (issued 2/19/98) & permit include schedule  requiring
  elimination of all overflow oufells by Dec. 31, 2012. The City requested a 4-year schedule extension in April 2007, due to economic hardship. The
  Department approved the City's request and issued a schedule  in the modified permit requiring elimination  of all overflow oufells by December  31, 2016;
  several oufalls and the associated  overflows have already been eliminated  through sewer separation construction.	
26 Long-term Control Program being implemented.  The reissued permit will require CSO correction  that may include a regional project with DWSD, with
  completion by 2025.	
27 Long-term Control Program has been implemented; the program included a presumptively sized retention/treatment  basin to provide adequate treatment of
  all combined sewer overflows (the facility went "on-line" and began treating overflows in 1999); remaining corrective projects have been completed and the
  project has been certified.  The permit required "Total Residual Chlorine Mixing Zone/Plume  Definition Study" has been submitted  and is currently under
  review by the Department.  The report evaluates whether or not the Total Residual Chlorine (TRC) discharges from the RTB cause violations of water quality
  standards.
28 Long-term Control Program complete; existing  retention/treatment basin provides adequate treatment to meet Water Quality Standards at times  of discharge.
 ' Long-term Control Program being implemented;  upgrades for too of the "RTBs" (Weiss St. RTB & 14th St. RTB) in order to provide for adequate treatment of
  all overflows has been completed; in accordance with the permit  & approved program, permittee is re-conducing a Retention/Treatment  Basin Evaluation
  Studies for the "East Side" system and "West Side" system to determine whether these facilities provide adequate treatment and whether facility  upgrade will
  be required; the original studies were not approvable.	
 ' Long-term Control Program (sewer separation  project) being implemented;  approved program with phased construction requires elimination of all discharges
  by Dec. 31, 2018.	
 1 Long-term Control Program currently considered complete (existing retention/treatment  facility); reissued permit requires a Water Quality Study (due October
  1, 2015) for a determination of whether the facility  provides adequate  treatment  of all overflows; Long-term Control Program for facility  upgrade and
  provisions for adequate treatment  may be required in the future. The  NPDES permit also requires the permittee to submit  a Hydraulic Capacity  Study for the
  Pine St PS. The study will be used to determine if any improvements  can be made to eliminate CSO discharges from the  Pine St PS.	
 - Long-term Control Program approved; program requires elimination of overflows through reduction of flows (via sewer rehabilitation, infiltration/inflow
  removal, et.) and transport of all flows to the wastewater treatment plant; on or before April 30, 2016, the permittee  shall submit apian and schedule for
  implementation of Corrective Measures. On or before November 30, 2017, the permittee  shall complete construction/implementation of the collection  system
  corrective  measures. The construction  for the in-line storage tanks shall be completed by November 30, 2020. A Project Performance  Certification  (PCC) will
  follow.
33 Long-term Control Program (sewer separation  project) was agreed to in February 1995 and modified  in June 1996 and includes sewer separation to eliminate
  discharges. A number of separation projects have been completed  to date, resulfng in elimination of all oufells. Permit is in the process of being revised to
  include a schedule for a system project performance cerflcation.	
34 Long-term Control Program revised in reissued permit; construction of retention/treatment basin is complete & facility  is "on-line" and the Department agrees
  that the  RTB protects  public health, eliminates raw sewage, protects the physical characteristics standard,  and does not impact biological  communities.  An
  evaluation of the RTB discharges on the dissolved oxygen standard has been submitted  and is under Department review. Oufells M18 S M19 have been
  eliminated and certified by December 2005 (flow has been directed to the existing RTB). The permit requires control of one oufell by October 2012. The
  reissued permit will require CSO correction that  may include a regional project with DWSD, with completion  by 2025.	
36 Long-term Control Program revised in reissued permit; construction of retention/treatment basin is complete & facility  is "on-line" and the Department agrees
  that the  RTB protects  public health, eliminates raw sewage, protects the physical characteristics standard,  and does not impact biological  communities.  An
  evaluation of the RTB discharges on the dissolved oxygen standard has been submitted  and is under Department review. Oufells M18 SM19 have been
  eliminated and certified by December 2005 (flow has been directed to the existing RTB). The permit requires control of one oufell by October 2012.
  Upcoming permit reissuance will likely include a schedule extension due to financial  considerations.	
 5 Long-term Control Program revised in reissued permit; the program will address the too remaining  "uncontrolled"  (i.e., untreated)  CSO oufells;  permit
  requires completion of construction  by July 1, 2015 of an approved program for facilities to meet criteria for elimination of raw sewage discharges & protection
  of public health, and to ensure compliance with water quality standards; the  Department agreed to a revised correction schedule for control of the remaining
  untreated oufalls based on the City of Inkster's financial demonstration.

1 Using dab from 2005-2013, the average annual statewide total volume of treated discharges of combined sewage from existing RTBswas 16,882 MG/year. In
2019, when Detroit provides disinfection for discharges from outfall 050A, that average (using 2005-2013 data) will increase to 28,833 MG/year. For reference,
during the time period 2005-2013, the average annual discharge of untreated CSOs was 16,348 MG/year (including discharges from Detroit outfall 050A).
2 RTBs designed under the Presumptive definition in Michigan are expected to discharge adequately treated combined sewage -4 times per year or less. Those
designed under the Demonstration definition areexpected to discharge adequately treated combined sewage -4-10 times peryear.
3 Generally, a 0.2" rainfall event might trigger a CSO. Using this estimate, and an average number of 0.2" or greater events occurring approximately 30-50 times
per year, a rough estimate of the number of events per outfall would be -30-50 times per year. In 1 988, Michigan had 61 3 untreated CSOs, in 201 3 there were
136 untreated CSOs remaining.

1 All CSO communities in the Great Lakes Basin in Illinois are in the Chicago metropolitan area and part ofthe Tunnel and Reservoir Plan (TARP). TARPwas
approved as the LTCP for the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC), the City of Chicago, and 40 satellite communities.
Therefore, while each individual community that is part of TARP is listed in this table, there is also a record for the TARP system as a whole because all LTCP
and CSO-related data is reported for TARP as a whole.

1 All CSO communities in the Great Lakes Basin in Illinois are in the Chicago metropolitan area and part ofthe Tunnel and Reservoir Plan (TARP). TARPwas
approved as the LTCP for the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC), the City of Chicago, and 40 satellite communities.
Therefore, while each individual community that is part of TARP is listed in this table, there is also a record for the TARP system as a whole because all LTCP
and CSO-related data is reported for TARP as a whole.
2 Illinois reported 41 CSO events from TARP in 2014. However, most ofthe events goto Chicago-area rivers and only one event went to Lake Michigan.

                                      Glossary
A
Altern ative Co mbined
Sewer Overflow (CSO)
Control Plan
Any CSO control plan that is
recognized by a regulatory
authority as an acceptable
CSO control plan but does
not meet the nine elements of
a long-term control plan as
documented in the CSO
Control Policy, and/or does
not meet the minimum
requirements for a long-term
control plan for a small
community under 75,000, as
described in the CSO Control
Policy. Examples include
sewer separation,
grandfathered or pre-policy
CSO control, and Tunnel and
Reservoir Plan.
B
Best Available
Technology Economically
Achievable (BAT)
Technology-based standard
established under the Clean
Water Act (CWA) for effluent
limitations in National
Pollutant Discharge
Elimination System (NPDES)
permits for toxic antim sd
nonconventional pollutants.
Best Conventional
Pollutant Control
Technology (BCT)
Technology-based standard
established under the C WA
for effluent limitations in
NPDES permits for
conventional pollutants,
including biochemical oxygen
demand, total suspended
solids, fecal coliform, pH, and
oil and grease.
Clean Water Act (CWA)
Refers to the Federal Water
Pollution Control Act
Amendments of 1972 (P.L.
92-500), 33 U.S.C. 1251 et
seq., as amended.
Combined Sewer
Overflow (CSO)
The discharge from a
combined sewer system at a
point prior to the publicly
owned treatment works
treatment plant.
Combined Sewer
Overflow (CSO) Control
Policy
An EPA policy published on
April 19,1994 (59 FR18688).
Combined Sewer
Overflow (CSO) Event
One or more overflows from a
combined sewer system
resulting from a wet weather
event that does not receive at
least primary clarification,
solids and floatables disposal,
and disinfection of the
effluent.
Combined Sewer
Overflow (CSO) Volume
The total volume (in millions
of gallons) of effluent
discharged in a combined
sewer overflow event.
Combined Sewer System
(CSS)
A wastewater collection
system owned by a state or
municipality [as defined by
section 502 (4) of the CWA]
that conveys sanitary
wastewaters (domestic,
commercial, and industrial
wastewaters) andstormwater
through a single-pipe system
to a publicly owned treatment
works treatment plant [as
defined in4O CFR4O3-3(p)].
Construction Grants
Program
Federal assistance program
authorized under Section 201
of the Clean Water Act to
make grants to states,
municipalities, and inter-
municipal or interstate
agencies for the construction
of publicly owned treatment
works.
Conventional Pollutants
The CWA defines
conventional pollutants that
include biochemical oxygen
demand, total suspended
solids, fecal coliform, pH, and
oil and grease.
                                                                                 Page | G-l

                                      Report to Congress on Combined Sewer Overflows to the Great Lakes Basin
D
Demonstration Approach
One of two methods
described in the CSO Control
Policy for developing a LTCP.
The CSO Control Policy
provides that a permittee
may demonstrate that a
selected control program is
adequate to meet the water
quality-based requirements
oftheCWA
Direct Discharger
For the purposes of this
Report to Congress, an
owner/operator of a
combined sewer system with
one or more combined sewer
overflow outfalls discharging
directly into one of the Great
Lakes.
Dissolved Oxygen (DO)
The oxygen freely available in
water, which is vital for
sustaining fish and other
aquatic life as well as for
preventing odors. DO levels
are considered one of the
most important indicators of
a water body's ability to
support desirable aquatic life.
Dry Weather Flow
Conditions
Hydraulic flow conditions
within the combined sewer
system resulting from one or
more of the following: flows
of domestic sewage, ground
water infiltration,
commercial and industrial
wastewaters, or any other
nonprecipitation event-
related flows (e.g., tidal
infiltration under certain
circumstances).
Floatables and Trash
Visible buoyant or semi-
buoyant solids including but
not limited to organic matter,
personal hygiene items,
plastics, styrofoam, paper,
rubber, glass, and wood.
G
Great Lakes Basin
The total watershed areas
within the United States
discharging into the Great
Lakes. Note that areas of
Canada also discharge into
the Great Lakes, but they are
not considered in this Report.
Green Infrastructure
An engineered structure or
natural feature that utilizes
natural processes to control
stormwater runoff as close to
its source as possible. Green
infrastructure reduces the
quantity and rate of
stormwater flows through the
processes of infiltration,
evapotranspiration, and
capture and use (i.e.,
rainwater harvesting).
H
Headworks of a
Wastewater Treatment
Plant
The initial structures,
devices, and processes
provided at a wastewater
treatment plant, including
screening, pumping,
measuring, and grit removal
facilities.
Infiltration
Stormwater and ground
water that enter a sewer
system through such means
as defective pipes, pipe joints,
connections, or manholes.
(Infiltration does not include
inflow).
Infiltration/Inflow(I/I)
The combined volume of flow
in a sewer system from both
infiltration and inflow.
Inflow
Water, other than
wastewater, that enters a
sewer system from sources
such as roof leaders, cellar
drains, yard drains, area
drains, foundation drains,
drains from springs and
swampy areas, manhole
covers, cross connections
between storm drains and
sanitary sewers, catch basins,
cooling towers, stormwater,
surface runoff, street waste
waters, and other drainage.
(Inflow does not include
infiltration).
Long-Term Control Plan
(LTCP)
A combined sewer overflow
control plan that is ultimately
intended to result in
compliance with the CWA.
LTCPs consider the site-
specific nature of combined
sewer overflows and evaluate
the cost-effectiveness of a
range of controls. The CSO
Control Policy describes two
                                                                                    Page | G-2

                                     Report to Congress on Combined Sewer Overflows to the Great Lakes Basin
approaches for selecting an
adequate level of control in
the LTCP - the presumption
approach and the
demonstration approach.
M
Major Publicly Owned
Treatment Works
(POTW)
A classification for POTWs
that are designed to
discharge i million or more
gallons per day. Some
publicly owned treatment
works with smaller design
flows are classified as major
when the NPDES authority
deems it necessary for a
specific NPDES permit to
have a stronger regulatory
focus.
Million Gallons per Day
(MOD)
A unit of flow commonly used
for wastewater discharges.
One million gallons per day is
equivalent to a flow rate of
1.547 cubic feet per second
over a 24-hour period.
Minor Publicly Owned
Treatment Works
(POTW)
A classification for POTWs
that are designed to
discharge less than i million
gallons per day.
N
National Pollutant
Disch arge Elimination
System (NPDES)
The national program for
issuing, modifying, revoking
and reissuing, terminating,
monitoring, and enforcing
permits, and imposing and
enforcing pretreatment
requirements under Sections
307,318, 402, and 405 of the
CWA
Nine Minimum Controls
(NMC)
Specific steps set forth in the
CSO Control Policythat
comprise the minimum
technology-based effluent
limitations to be included in a
NPDES permit for combined
sewer overflows.
Nutrient
A compound that is necessary
for metabolism.
Point Source
Defined in section 502(14) of
the CWA as any discernible,
confined, and discrete
conveyance, including but
not limited to any pipe, ditch,
channel, tunnel, conduit,
well, discrete fixture,
container, rolling stock,
concentrated animal feeding
operation, landfill leachate
collection system, vessel, or
other floating craft from
which pollutants are or may
could be discharged. The
term does not include
agricultural stormwater
discharges and return flows
from irrigated agriculture.
Post-Construction
Compliance Monitoring
A water quality monitoring
program to verify compliance
with WQSs and protection of
designated uses as well as to
ascertain the effectiveness of
combined sewer overflow
controls after completion of
construction called for in the
long-term control plan, as
described in Section 11. C. 9 of
the CSO Control Policy.
Presu mption Approach
One of two methods
described in the CSO Control
Policy for developing a LTCP.
The CSO Control Policy
provides that a program in a
LTCP that meets certain
minimum performance
criteria defined in the Policy
".. .would be presumed to
provide an adequate level of
control to meet the water
quality-based requirements
of the CWA, provided the
permitting authority
determines that such
presumption is reasonable in
light of the data and analysis
conducted in the
characterization, monitoring,
and modeling of the system
and the consideration of
sensitive areas..." (CSO
Control Policy II.C.4.a).
Primary Treatment
First steps in wastewater
treatment wherein screens
and sedimentation tanks are
used to remove most
materials that float or will
settle. For purposes of this
Report, "primary treatment"
means the same as "primary
treatment or equivalent
treatment" in Section 3Oi(h)
of the CWA: "treatment by
screening, sedimentation,
and skimming adequate to
remove 30 percent of
biochemical oxygen demand
(BOD) and 30 percent of
suspended solids."

Publicly Owned
Treatment Works
(POTW)
As defined in 40 CFR
4O3-3(q), a treatment works
as defined by section 212 of
the CWAthat is owned by a
state or municipality. This
definition includes any
devices and systems used in
the storage, treatment,
recycling, and reclamation of
municipal sewage or
industrial wastes of a liquid
nature. It also includes
sewers, pipes, and other
conveyances only if they
convey wastewater to a
publicly owned treatment
works treatment plant.
Sanitary Sewer Overflow
(SSO)
An untreated or partially
treated sewage release from a
separate sanitary sewer
system.
Secondary Treatment
Technology-based
requirements for discharges
from municipal sewage
treatment facilities. 40 CFR
133.102 defines secondary
treatment as so-day averages
of 30 milligrams per liter
BOD  and 30 milligrams per
liter suspended solids, along
with maintenance of pH
within 6. o to 9.0 (except as
provided for special
considerations and treatment
equivalent to secondary
treatment).
Separate Sanitary Sewer
(SSS)
A municipal wastewater
collection system that
conveys domestic,
commercial, and industrial
wastewater, andlimited
amounts of infiltrated ground
water and stormwater to a
publicly owned treatment
works treatment plant. Areas
served by separate sanitary
sewer systems often have a
municipal separate storm
sewer system to collect and
convey runoff from rainfall
andsnowmelt.
Sewer Separation
The practice of separating a
combined sewer system into
storm sewers for stormwater
flows and separate sanitary
sewers for sanitary flows.
State Revolving Fund
(SRF) Program
A federal program created by
the CWA Amendments in
1987 that offers low-interest
loans for wastewater
treatment projects.
Total Suspended Solids
(TSS)
A measure of the filterable
solids present in a sample of
water or wastewater (as
determined by the method
specified in 40 CFR Part 136).
Toxics
Materials contaminating the
environment that cause
death, disease, and/or birth
defects in organisms that
ingest or absorb them. The
quantities and length of
