Acknowledgements and Information This annual report is part of a series of reports that consolidate annual release reporting data: CSO/SSO Annual Report for 2006 CSO/SSO Annual Report for 2005 CSO/SSO Annual Report for 2004 CSO/SSO Annual Report for 2002 and 2003 CSO & SSO Annual Report - July 2000 - December 2001 This 2007 report was expanded to capture the history of CSO control in Michigan. This historical section was developed by DEQ staff to document and preserve information about this important control effort for present and future generations. An invaluable part of this publication were the comments provided by retired State of Michigan employees who were directly involved in CSO control during the 1980 s and early 1990 s. Of special note is Paul Zugger, who was Chief of the Department s Surface Water Quality Division during this time; he provided the leadership necessary for the development of our CSO control strategy. A heart-felt thanks to Paul for providing comments that helped turn a listing of historical events into an informative story. In addition, we would like to extend special thanks to Paul Blakeslee, the Department s former CSO specialist, who likewise assisted with the development and review of the CSO historical section. As the former departmental specialist and manager responsible for assuring completion of the very first CSO/SSO annual release report (2000 2001), he supported the vision of the inclusion of public education information within these annual release reports. His assistance helped assure an accurate accounting of CSO control history and his focus on the integration of public education is very much appreciated.

A Message from the Director Thank you for taking the time to learn about Combined Sewer Overflows (CSOs) and Sanitary Sewer Overflows (SSOs) in Michigan. This report contains 2007 annual release reporting information along with a special feature providing the history of how Michigan became a national leader in CSO control. This year s special CSO Historical Section documents and preserves for history the extensive investment that has been made in public infrastructure to address this important public health problem. Perhaps the seriousness of this challenge can best be understood through an expression of progress. The good news is that Michigan communities have eliminated 75 percent of the CSO outfalls that existed in 1988 with the expenditure of over $2 billion. This is an excellent example of how public investment in pollution control and infrastructure can improve our water resources for public safety and enjoyment. Yet even with this investment and progress, it is still expected to cost an additional $2.875 billion for continuance of construction work on CSO projects (in 2007 dollars) to address the remaining 25 percent of the CSO outfalls. There is still much progress to make, but our efforts appear to be having a significant impact. As expressed above, addressing CSOs and SSOs is a multiyear, multibillion dollar challenge. As such, yearly progress seems minimal when compared to 20 years of progress. However, the sharing of yearly achievements can help all of us recognize the steady gains that we are making toward our long-term goals. During 2007, the DEQ awarded nearly $300 million in low-interest loan assistance for projects to address sewer overflows. The cities of Lansing and Port Huron received assistance for ongoing combined sewer separation programs, while Detroit and Dearborn received assistance for additional retention/treatment facilities. Significant State Revolving Fund investments were also made in Genesee County s regional sewer system and in the city of Harbor Beach to address chronic SSO problems. Assistance from the Strategic Water Quality Initiatives Fund is being used for a footing drain disconnection program in Ann Arbor, while a number of other communities with wet sanitary systems are conducting flow monitoring work as a prerequisite to seeking loan funding to address system capacity problems. Aside from financial aspects of CSO control, annual progress has been measured in terms of CSO outfall elimination, along with volume and number of CSO events in comparison to previous reporting years. In terms of CSO outfall elimination, which is a good indicator of the implementation of construction projects pursuant to long-term control plans, ten CSO outfalls were eliminated in 2007. The city of Dearborn eliminated three, the city of Lansing eliminated two, and the city of St. Joseph eliminated five. For CSOs, both event numbers and volume of
discharge appear to be closely related to rainfall in any given year (see Figures 7, 8, and 9 on pages 34 and 35). However, it is expected that the amount of partially treated releases will become a greater percentage of the overall CSO discharge volume as control plans are implemented. SSO control has been measured in past reports by the number of administrative settlements that were entered between the DEQ and facilities that are addressing SSO issues along with some trend data from past reporting years. In 2007, the DEQ entered into four administrative settlements with municipalities that require corrective actions to address SSOs. These were with the cities of Northville, Plymouth, Westland, and Garden City. In addition, an agreement was reached with the city of Grand Rapids that resolved violations associated with an SSO event in December 2004 and requires the submittal of an updated Emergency Response Plan. Based on seven years of SSO data, a downward trend in the volume of SSOs is evident (see Figure 11 on page 44). As expressed in the CSO Historical Section of this report, a Michigan citizenry with a strong environmental ethic has already played an important role in advancing CSO control in Michigan. You can continue to provide vital assistance to address and eliminate many of these discharges from entering the environment. Please continue your Web site visit and learn whether your community is causing, or is impacted by, these discharges. Providing support to your community to address these discharges will help promote a healthy environment that is critical to our social, cultural, and economic well-being. Sincerely, Steven E. Chester, Director Michigan Department of Environmental Quality
Introduction The DEQ is concerned about releases of raw and partially treated sewage from municipal and privately owned sewer systems, an environmental and public health problem that has plagued Michigan for decades. The State of Michigan took a more aggressive approach to address these discharges in 1988 by initiating an aggressive Combined Sewer Overflow (CSO) control program and in the year 2000 by adopting a Sanitary Sewer Overflow (SSO) control strategy. As part of the 2000 initiative, local units of government were called upon to step up to the plate to help protect Michigan s waters. This report is one step in addressing these types of discharges for the people of Michigan. Specifically, it defines and publicizes the extent of this statewide problem and the actions being taken to control these discharges. What Is the Difference between a Sanitary Sewer System and a Combined Sewer System? In order to understand the difference between a CSO and an SSO, it is necessary to understand some basics of sewer system design. Separate sanitary sewers are designed to carry only sanitary sewage to a wastewater treatment plant (WWTP) (see Figure 1); storm water is directed to a nearby river, lake or stream via storm sewers. Combined sewer systems are generally older sewer systems designed to convey both sewage and storm water (combined in one pipe) to a WWTP (see Figure 2). Generally, combined sewer systems were designed with overflow points in the sewer system and/or at the WWTP. This is because the system can not handle all the volume of water that is associated with some larger storm water events. As part of corrective action programs, many combined sewer systems have installed or are installing Retention Treatment Facilities (RTFs), which are designed to capture the combined sewage and rain water that would otherwise flow to surface waters untreated. These basins hold the combined sewage long enough to provide treatment and disinfection before the combined sewage is released into waters of the state during periods of intense precipitation (see Figure 3). In General, What are CSOs and SSOs? CSOs are releases of raw or partially treated sewage from older combined sewer systems designed to carry both sanitary sewage and storm water. SSOs are releases of raw or inadequately treated sewage from separate sanitary sewer systems, which are designed to carry sanitary sewage but not storm water. Both CSO and SSO events discharge untreated or partially treated human and industrial waste, toxic materials, debris and disease causing organisms on to the ground or into our rivers, lakes or streams. 1

What Laws Require Reporting of CSO and SSO Releases? Section 324.3112(a) of the Natural Resources and Environmental Protection Act (NREPA), Public Act 451 of 1994, as amended requires responsible parties to report releases of untreated or partially treated sanitary sewage. Section 324.3112(c) of NREPA requires an annual reporting of these releases. This section was added in July, 2000. The Michigan Department of Environmental Quality (DEQ) has produced this report as a means of providing the public with information regarding known discharge of untreated and partially treated sewage to land and waters of the state. Prior to 2004, only releases from municipalities were required to be reported. However, in 2004, Section 324.3112a was amended to include reporting of treated and partially treated sewage releases from private systems (system serving more than a duplex). Who Will Let Me Know Whether the Water Is Safe for Swimming, Fishing or Canoeing? When raw or partially treated sewage is released into a river, lake or stream, the responsible party is required to notify the local health department and others as specified in the law. The local health department may sample, or may require the responsible party to sample, the waterbody that received the sewage discharge. If the discharge poses a public health threat, then the local health department is responsible for issuing a public health advisory to notify people of the dangers associated with river or lake water contact. Additionally, the local health department gathers information related to health aspects of water pollution for public and semi-public beaches (this activity may not be specifically related to CSO and SSO releases). They issue swimming advisories and track reported illnesses related to water borne organisms. Some local health departments provide citizens with information and resources to do their own beach monitoring. More information about water quality monitoring related to health aspects of water pollution, including a list of local health departments with phone numbers can be found online through the state of Michigan Beach Monitoring Website found at: www.deq.state.mi.us/beach. Phone books also contain local health department contact information. When searching the phone book, look for either the county health department or the district health department for your area. How Does Intergovernmental Cooperation Help Fund Infrastructure Improvements? The Clean Water State Revolving Fund (CWSRF or SRF) and the Strategic Water Quality Initiatives Fund (SWQIF) remain the primary sources of financial assistance for local units of government facing wastewater infrastructure investment needs. Created in 1989 and capitalized with Federal grant funds and a required state match, the SRF has tendered over $2.8 billion in loan assistance to Michigan communities for the construction, expansion and upgrade of publicly owned sewers and wastewater treatment facilities. Fully one-half of this assistance has been expended for projects to address combined sewer overflows. Remediation of sanitary sewer overflows and addressing non-point sources of pollution are increasingly becoming a focus of the SRF. The passage of the $1 billion Great Lakes Water Quality Bond referendum in November of 2002 (Proposal 2) injected additional capital into the SRF, dramatically increasing its annual lending capacity. That vote also created the SWQIF, another revolving loan fund that provides low interest loan assistance for wastewater system improvements that remain in private ownership. The portion of Proposal 2 monies dedicated to the SWQIF is available for projects that remove clear water from sewer leads on private property (often a component of successful SSO projects) or for projects to upgrade or replace failing on-site wastewater systems. A portion of these funds ($40 million) was used to provide grants to assist loan 4
applicants with completing the planning and design of their projects. The revolving funds will operate in perpetuity and result in significant cost savings for system owners and users compared to open market financing alternatives, while remaining the primary source of funding for water quality protection efforts in the state.

Report Terms and Acronyms For the purposes of this report, the following terms and acronyms are described below. Explanation of Report Headings: EventID: A unique internal DEQ tracking number assigned to an event. If you have questions about a specific event, or need additional information, providing this number to the DEQ district office staff in your area will assist them in finding the correct information. Start Date/Time: The date and time the CSO/SSO discharge event began. If there were multiple discharge locations associated with a single event, all discharging at different dates/times, then this is the date/time of the earliest discharge. End Date/Time: The date and time the CSO/SSO discharge event ended. If there were multiple discharge locations associated with a single event, all discharging at different dates/times, then this is the date/time of the latest discharge. Event Volume: Total CSO/SSO discharge volume for the event (in millions of gallons) reported by the responsible party. This value can be an estimated value as is often the case with SSOs. When the report lists Not Specified, no volume information was reported to the DEQ. Discharge Quality: Description of the quality of the wastewater discharged. See Acronym/Definitions section for detailed explanations. Point(s) of Discharge: Narrative description of wastewater discharge location(s) (separated by *** where multiple points of discharge occurred during a single event). It provides information about receiving waters and/or land areas impacted by the discharge. A three digit number preceding a receiving water name is the permittee s outfall discharge location as listed in their NPDES permit. When the report lists Not Specified, discharge information was not reported to the DEQ for the land area or waterbody impacted. Note that this term is used in the appendix. Control Program: For CSOs this area of the report provides information and status of the permittee s long term control program corrective actions as contained in their NPDES permit. Outfall Corrective Actions: For SSOs this area of the report provides information regarding corrective actions taken to reduce/eliminate future discharges from a particular SSO outfall discharge location (Note: these corrective actions do not pertain to a specific discharge event or to the owner of the sewer system as a whole). The specific locations where these corrective actions have taken place are listed under Associated Outfall(s). Definitions/Acronyms: Adequately Treated: CSO discharges that have been demonstrated to meet Water Quality Standards or discharges from an RTF that was designed to meet the presumptive regulatory approach. Clear Water: Clear Water is non-sanitary or non-industrial wastewater that may enter the sewer system. It includes, but is not limited to: groundwater that seeps in through cracks in the sewer pipes; rain water or snow-melt that flows into the sanitary system through improperly connected roof drains; groundwater that enters from footing drains and sump pumps; and storm water that enters when storm sewers are inadvertently connected to the sanitary sewer. Collection System: System of subsurface sewer pipes designed and used to convey either sanitary sewage or both sanitary sewage and storm water to a wastewater treatment plant. Combined Sewer: Sanitary sewage and storm water are conveyed in the same (combined) sewer pipe. CSO: Combined Sewer Overflow Demonstrative Regulatory Approach: For CSO retention treatment facilities that are built based on approved designs that are less conservative then the presumptive approach, and 7
therefore require a demonstration upon completion of construction to prove that discharges meet Water Quality Standards. DEQ: The State of Michigan s Department of Environmental Quality Diluted Sanitary Sewage: Sanitary sewage diluted with rain water, snow melt, or ground water. Infiltration/Inflow (I/I): rainwater, snowmelt, or groundwater flowing into separate sanitary or combined sewers via connected roof downspouts and/or building footing drains or infiltrating into the pipe through cracks in the pipe walls or joints. MG: Million Gallons, e.g., 24,000 gallons = 0.024 MG MH: Manhole NPDES Permit: National Pollutant Discharge Elimination System Permit. A permit issued by the DEQ, authorized under the federal Clean Water Act, to discharge treated wastewater to waters of the United States. mg/l: Milligrams per liter, concentration unit equivalent to parts per million. Outfall: Point of discharge of treated, partially treated or untreated wastewaters to surface waters of the state. Partially Treated Sewage: Any sewage, sewage and storm water, or sewage and wastewater, from domestic or industrial sources that meets 1 or more of the following: 1) Is not treated to national secondary treatment standards for wastewater or that is treated to a level less than that required by the person s National Pollutant Discharge Elimination System Permit; 2) Is treated to a level less than that required by the person s Groundwater Discharge Permit; and 3) Is found on the ground surface (Section 324.3112c of NREPA). Presumptive Regulatory Approach: For CSO facilities that are designed using a conservative engineering approach. In this approach, meeting WQS is assumed and there is no need for a demonstration following completion of construction. PS: Pump station Raw Sewage: Untreated sanitary sewage. RTB & RTF: Retention Treatment Basin or, more generally, Retention Treatment Facility used for treatment of combined sewage. Separate Sanitary Sewer: Separate sanitary sewer pipe, designed to convey only sanitary sewage and minor amounts of infiltration and inflow to a wastewater treatment facility. Sewer System: A public or privately owned wastewater collection facility designed and used to convey or treat sanitary sewage or sanitary sewage and storm water. Sewer system does not include an on-site wastewater treatment system serving 1 residential unit or duplex. SSO: Sanitary Sewer Overflow Surface Waters of the State: e.g., rivers, streams, creeks, lakes, some open ditches, and wetlands (as opposed to ground waters, i.e., aquifers). TSS: Total Suspended Solids Twp: Township WQS: Water Quality Standards are regulations that establish the uses for which surface waters of the state are protected and include numeric and narrative criteria to protect those uses. WWTP: Wastewater Treatment Plant or other treatment facility such as a treatment lagoon. 8
Michigan's History of Combined Sewer Overflow Control What were the Milestones and Drivers of CSO Control in Michigan? A number of factors enabled Michigan to become the national leader in CSO control. Primary among these were a citizenry with a strong environmental ethic, a state agency prepared to take on this controversial and costly issue, and leadership and political will at the state and local level to get it done. The drivers of the CSO control program include public outcry, international treaties, water quality agreements, federal law, state laws and rules, and most notably an overwhelming need to protect public health and the ability of citizens to safely swim and fish in our waters. Michigan's program evolved to focus on CSOs after water pollution control efforts driven by strong state water laws of the 1970 s and the federal Clean Water Act of 1972 improved water quality in surface waters, especially downstream of urban areas allowing these waters to be used for recreational purposes. People once again started to enjoy these waters. It became clear that the impacts on recreational use of waters and the threat to public health caused by overflows from combined sewers, mixing raw sewage with storm water during wet weather conditions, could no longer be tolerated. The control of raw sewage discharges during wet weather was necessary for the protection of public health. Once the problem was recognized, most Michigan municipalities committed substantial local resources to cooperatively pursue plans with the state and federal governments to remedy this large and costly water pollution concern. Many stakeholders and agencies have played important roles in advancing CSO control in Michigan. These include most notably the citizens and public interest groups, municipalities, the Michigan Water Resources Commission, the Michigan Department of Environmental Quality (formerly organized within the Department of Natural Resources, "Department"), the federal Environmental Protection Agency (EPA) and Federal District Court Judge John Feikens. The following is a timeline of water pollution and CSO control in Michigan: 1909 Boundary Waters Treaty was signed. Boundary Waters Treaty was entered into between the United States and Great Britain, relating to boundary waters between the United States and Canada. This agreement provided a mechanism for the two countries (United States and Canada) to prevent disputes and settle questions regarding the boundary waters between the two countries. The treaty provided in Article IV: "It is further agreed that the boundary waters and waters flowing across the boundary shall not be polluted on either side to the injury of health and property of the other." The International Joint Commission (IJC) was established through this treaty. This commission has provided the basis for resolving differences between the two nations through shared information and common understandings that are developed through IJC consultative processes. 1929 Establishment of the Stream Control Commission PA 245 of 1929 established the Michigan Stream Control Commission, which was authorized to control the management of Michigan s streams and rivers. PA 117 of 1949 changed the name of the commission to the Water Resources Commission and vastly 9
increased the scope of the commission s authority to address all waters of the state, including groundwater and the Great Lakes, and strengthened its authority to control water pollution. The Water Resources Commission was in charge of protecting and conserving the water resources of the state until it was abolished in 1994. 1960's Municipalities stopped building combined sewer systems. Most municipalities in the Great Lakes basin stopped building combined sewer systems. Expansions to existing systems were with separate sanitary and storm sewers resulting in many systems having a mix (old combined and new separate systems). 1966 Unlawful pollution is defined in law. PA 328 of 1965 (effective March 31, 1966) changed the Michigan Water Resources Commission Act PA 245 of 1929, as amended, to expand the definition of unlawful pollution, making the discharge of raw sewage prima facie evidence of a violation of the act and holding municipalities responsible for correction. This language is now contained in MCL 324.3109(2), Part 31, Water Resources Protection of PA 451 of 1994, as amended: 323.6(2) "The discharge of any raw sewage of human origin, directly or indirectly into any of the waters of the state shall be considered prima facie evidence of a violation of this act by the municipality in which the discharge originated unless the discharge shall have been permitted by an order or rule of the commission." Municipalities were therefore responsible for the control of the all sewage generated within the municipality. These changes led to a significant increase in the construction of sewers and treatment plants. CSOs, however, were rarely addressed as the primary focus was on addressing continuous (dry weather) discharges of inadequately treated sewage. 1972 Great Lakes Water Quality Agreement This Agreement between the United States and Canada called on governments, industry, agriculture and the people of these two countries to work together to clean up the Great Lakes environment. This 1972 agreement also required the identification of problem areas with degraded water quality due to pollution from industrial, municipal or non-point sources. The Detroit River was listed as a problem area (Category A Area of Concern) due to point source discharges, including upstream inputs. The Agreement helped drive the construction of additional treatment facilities, but did not focus on CSOs. 1972 United States strengthened the Clean Water Act. The Federal Water Pollution Control Act (now called the Clean Water Act, P.L. 92 500) objective is "to restore and maintain the chemical, physical, and biological integrity of the Nation's waters." The Act established an interim goal of fishable and swimmable waters wherever attainable by 1983 and established the National Pollutant Discharge Elimination System (NPDES) requiring a discharge permit for all point source discharges of wastewater into the nation's waters. Michigan was one of the first states to submit an approvable program to EPA and was the fourth state that received federal authorization to administer the NPDES program. 10
The Clean Water Act required all municipalities to provide, as a minimum, secondary treatment of sewage. This mandate placed a huge financial burden on the nation s cities and to help deal with that, the Act authorized greatly expanded funding for a new Construction Grants Program for municipal wastewater infrastructure improvements (Clean Water Act Section 201). Most investment in municipal facilities during the decade after the Clean Water Act focused on new and upgraded treatment plants (secondary and advanced treatment where needed) and collection systems. Wet weather issues were seldom directly addressed except where new separate sewers replaced old combined sewers. In some areas, however, where CSOs were identified as causing severe water quality problems, communities constructed CSO controls utilizing construction grant funds. These improvements were made well before this problem was getting much statewide attention, and inmost cases, had to be upgraded in subsequent years. Milk River: The initial CSO structure (3.5 million gallon retention treatment facility) was built in 1960. This initial CSO structure was upgraded or replaced in 1994 with a 19 million gallon facility. South Macomb Sanitation District: The initial Martin and Chapaton CSO basins were constructed in 1969; these systems were subsequently updated during the years 2000 through 2003. Oakland Co GWK RTF (Oakland Co SOCSDS 12 Towns RTB): The initial CSO facility (66 million gallon retention treatment storage tunnel) was constructed in 1972 with a federal grant for $11,739,566 and it was accompanied by a state grant of $5,336,167; a total project cost of approximately $21.3 million. Subsequently, additional sewers were separated and the initial CSO facility was upgraded during the years 1998 to 2007. Bay City (Bay City WWTP): The initial CSO facility consisted of five retention treatment basins constructed in 1977 with $30 million in construction grant funds. A subsequent upgrade to the WWTP and basins was undertaken in 2001. The performance of these basins is currently being reviewed to see if upgrades are needed. Southgate Wyandotte: The initial CSO facility (a 15 million gallon retention treatment facility) was constructed in 1977 with $45,875,000 in construction grant funds. The performance of this facility is currently being reviewed to see if upgrades are needed. 1977 Detroit WWTP lawsuit began. Detroit's WWTP was identified in various Great Lakes research projects (associated with the Great Lakes Water Quality Agreement) as the largest discharger of phosphorus to the Great Lakes system. Detroit, along with several municipalities tributary to the Detroit WWTP collection system, were sued by the federal government (and later joined by the State of Michigan) to address permit violations that required secondary treatment and phosphorus control from the City of Detroit's WWTP. This action was initially filed to seek full secondary treatment with phosphorus removal and for industrial pretreatment issues. By 1980, Detroit had spent $350 million over the prior 10 year period but had missed an interim compliance requirement in July 1978. The Mayor of the City was then appointed administrator of the plant, subject only to the Court, under the direction of the Honorable John Feikens of the United States District Court, Eastern District of Michigan, Southern Division. Judge Feikens appointed Charles Moon and Dr. Jonathon W. 11
Bulkley, P.E. to assist the court in guiding Detroit and their contributing communities. Detroit was required to achieve full secondary treatment with phosphorus removal in the early 1980's. By the mid to late 1980's the court and parties were ready to discuss wet weather discharges. Judge Feikens eventually returned enforcement oversight of the wastewater discharges to the Water Resources Commission and the Department. The court still oversees Detroit's progress and is currently involved in a rate dispute. 1978 Great Lakes Water Quality Agreement Renewal The Great Lakes Water Quality Agreement was renewed introducing an ecosystem approach, which considers the interaction of air, land, water and all living organisms including humans in an effort to clean up the Great Lakes. The US and Canada also agreed to the development and implementation of practical programs for reducing pollution from storm, sanitary and combined sewer discharges. The Detroit River and Rouge River basin were both designated "Class A" Areas of Concern at this time. 1983 The Department's 1983 CSO Policy Up until this time, the Department's attention had been directed towards the control of continuous discharges, especially point source discharges regulated under the NPDES program. By the mid 1980 s virtually all of the municipal wastewater treatment plants (of which there were over 400) in Michigan had achieved compliance with the Clean Water Act requirement to at least provide secondary treatment of all continuous flows. Michigan s treatment plants were also required to reduce phosphorous loadings to control nutrient impacts in the Great Lakes Basin in accordance with commitments made under the Great Lakes Water Quality Agreement. It was becoming clear, however, that in many areas of the state, CSOs had to be addressed to achieve the state s water quality goals and assure public health protection. To start to deal with this issue on a broad basis, the Department developed a draft CSO policy. The draft policy aimed to define the problem and provide overall direction and priorities for action. Dry weather discharges from sanitary and combined sewers not due to storm events were considered controllable discharges and would be permitted and controlled in the same manner as other continuous discharges. Under the policy, the Department would identify waters that were impaired to the point of not meeting protected designated uses due to intermittent wet weather discharges from sewer systems and initiate action to require necessary corrective programs. In effect, the policy relied on demonstrated water quality impairment to justify action. For example, in 1983 Grand Rapids and Lansing were studied in context of qualifying for funding under the Clean Water Act's Construction Grants program (Section 201) and it was concluded that there was insufficient demonstrated water quality impairment to qualify these areas for Section 201 funding for CSO correction. 1985 Refinement of CSO Terminology CSO was a catchall term for wet weather discharges from WWTPs and their collection systems (including SSOs and bypasses). To distinguish and determine what level of control was required for CSOs under the Clean Water Act, EPA defined CSOs as discharges from a combined system due to wet weather events that occurred prior to the collected flows reaching the headworks of a treatment facility. Emergency intentional releases within the POTW were identified as bypasses. This categorization of wet weather discharges was refined over time as the Department's control program developed, but clear definitions were difficult, especially in large systems that had both separated and combined sewers. Also, many systems had what came to be referred to as wet sanitary systems that were separated sanitary sewers with excessive rainwater 12
of groundwater inflow and infiltration. Some of the systems listed in 1988 as CSOs were actually wet sanitary systems, and the discharges were not CSOs but are SSOs under today s definitions. Under state and federal law, SSOs must receive secondary treatment. 1985 Control of Rouge River CSOs on Water Resources Commission s Agenda In July 1985 the Michigan Water Resources Commission recognized the Rouge River as an extremely valuable resource with a "deplorable and intolerable" environmental condition. The commission committed to do all in its power to restore the Rouge River. In October of that same year, they adopted a "Rouge River Basin Strategy" that highlighted CSOs as the most notable concern in the basin and outlined an action-based strategy to address CSOs in the Rouge River. 1986 Water Quality Standards Revision for Total Body Contact Recreation In November of 1986, Michigan's Part 4 Rules, Water Quality Standards, 1979 AC, R 323.1041-323.1117, were revised to protect all surface waters of the state for total body contact recreation (swimming). This change strengthened the state s ability to require correction of CSOs. 1987 Amendments of Great Lakes Water Quality Agreement The Great Lakes Water Quality Agreement was strengthened in 1987 to require more specific measures for cleanup of the local areas of concern. Community members and governments were called on to work together to develop "Remedial Action Plans" to address identified impairments. Several Southeast Michigan Watersheds were listed as Areas of Concern and uncontrolled CSO discharges were identified as a major source of pollution throughout much of the Rouge River Basin, the Clinton River Basin, and portions of the Lake St. Clair and Detroit River shoreline. 1987 CSO control was added to NPDES permits. In September 1987, NPDES permits were issued to Lansing, Port Huron and Belding containing new CSO control requirements. These permits established a phased approach to eliminate or provide adequate treatment for CSOs. Long term programs were to be developed and implemented under fixed date schedules established in subsequent permits, and interim corrections were to be pursued immediately. Those CSO correction requirements of these permits were contested by the municipalities for being too vague and also because municipalities realized that major expenditures of public works funds would be involved in implementing corrections. The Department formed a CSO advisory committee consisting of key stakeholders and Department staff with the purpose of developing consensus CSO language for future permits. Consensus was not reached, however, and the Department staff proposed a revised approach to the Water Resources Commission that was more specific. The Department recommended that the commission issue CSO permits that provided specific treatment requirements but also provided flexibility. The commission accepted this recommendation and directed staff to draft permits for issuance with these CSO requirements. However, stakeholders, especially municipalities, continued to object to these requirements. 1988 The stalemate ends. In the fall of 1988, a large CSO event in Grand Rapids ended the stalemate. A major storm following a long drought resulted in large CSOs causing water quality impacts as far downstream as Grand Haven. Public health agencies issued warnings against any 13
contact with the river water, and the issue received wide-spread attention in the press and at all level of government. Downstream communities, public interest groups (such as Western Michigan Environmental Action Council and Michigan United Conservations Clubs), legislators, the press, and individual citizens all demanded action. Bumper stickers adorned vehicles with statements like "When it Rains, Grand Rapids Flushes." This public awakening was driven in part by the improved water quality due to tighter regulation control of continuous discharges from industries and cities over the previous two decades. As a result of these water quality improvements, citizens were using the rivers and streams in urban areas for recreation, and the idea that raw sewage was being discharged during large storm events was clearly not acceptable. Prior to this major overflow event, the Department had already presented a draft permit to the city of Grand Rapids, with requirements for a long term CSO correction program including the construction of a large storage basin. In response to the public outcry, the Michigan Attorney General and the Director of the Department held a press conference in Grand Rapids to announce their joint intent to take enforcement action to require corrective action. Following this event, the city agreed to the permit as proposed and on September 15, 1988 the first non-contested permit requiring a long term CSO correction program was issued. Grand Rapids was able to secure a Clean Water Act Section 201 Construction grant for construction of the required storage basin, which is called the Grand Rapids Market Avenue Retention Basin. The cost was $29,670,000 when it was constructed in 1989. (More recent improvements are summarized in the SRF summary report.) The Department also required Grand Rapids to institute a notification system by which local health departments would be advised of overflows and be able to issue prompt public health advisories. This notification process was an essential component of the CSO corrective program. The Department subsequently issued a letter to all Michigan CSO Daryl Smith, former Grand Rapids WWTP Superintendent and member of the Municipal Wastewater Operator Certification Board along with the Department s Paul Zugger, former Chief of Surface Water Quality Division and Fred Eyer, former Grand Rapids District Supervisor in the Grand Rapids WWTP Control Building. communities advising them that long term CSO controls would be required in NPDES permits, and public notifications of overflows would be required. CSO communities were invited by the Department to formulate the basis of an effective CSO notification system, which would assure that local health agencies would be provided the necessary information to issue advisories when appropriate. As a result overflows were reported statewide and public health advisories were placed on many waterways. 14
The Department also advised communities of the possibility of a moratorium on sewer construction permits (required by Part 41 of NREPA and issued by the Department) unless certain conditions such as off-set programs and schedules for design and construction of control facilities were met. The off-set program provided that any increase in sewage loading to the system had to be off-set by a corresponding removal of storm water from the system at a ratio of five gallons of storm water for one gallon of new sanitary flow. The sewer moratorium and offset program provided another strong incentive for CSO correction. 1988 Bond proposal passes and launches state match for SRF. Michigan voters passed the "Quality of Life Bond" proposal in the Fall of 1988. Sixty million dollars of the bond was targeted as Michigan's match for $350 million of federal grants for the Clean Water State Revolving Fund (CWSRF or SRF) program. The Department took the necessary steps (e.g. rule promulgation, application to EPA) to begin program implementation in the Fall of 1989. While funds can be obtained through various sources, the SRF is the primary source of financial assistance for local units of government facing wastewater infrastructure investment needs. Capitalized with federal grant funds, a required state match and funds from Michigan's Great Lakes Water Quality Bond Fund, as of 2007 the SRF has tendered nearly $1.5 billion in loan assistance to Michigan communities for projects to address combined sewer overflows. It is noteworthy to mention that in today's dollars this number would be much higher because this number is not normalized. Since program inception, the Department has been committed to making this program function in a manner that would provide the maximum benefit to municipalities pursuing critical water pollution control projects. In December 2003, EPA published a Clean Water State Revolving Fund (CWSRF) Fact Sheet: Funding Wet Weather Projects with the Clean Water State Revolving Fund. In their article entitled Addressing CSOs in Michigan, EPA acknowledged: "The CWSRF contribution to Michigan's ambitious CSO program serves as a model for other states' stormwater permitting processes." 1989 The Department's 1989 CSO Control Policy In January of 1989 the Department outlined a multi-phase approach to addressing CSOs. The goal of the 1989 policy was to issue/reissue NPDES permits for all CSOs and have all overflows under a corrective program within that year. The Rouge River in Southeast Michigan was a primary focus of the 1989 policy due to the severe CSO impacts. The Department was working closely with Rouge River communities and the Southeast Michigan Council of Governments (SEMCOG) in developing a Remedial Action Plan (RAP) for the Rouge River as required under the Great Lakes Water Quality Agreement, Annex II (1987). The RAP recommended basinwide CSO correction as the key initiative necessary to restore the designated uses of the Rouge River Basin. The RAP also highlighted the need for NPDES permits to establish requirements for the correction of CSOs. 1989 National CSO Control Strategy In August of 1989, EPA issued a National CSO Control Strategy that required states to develop a state-wide permitting strategy to address CSOs through NPDES no later than January 15, 1990. 1990 Michigan's State-Wide CSO Permitting Strategy Based on the Department s 1989 CSO Policy, the Water Resources Commission 15
approved Michigan's State-Wide CSO Permitting Strategy on January 15, 1990, which was based upon the Department s CSO Policy and the approach followed in the Grand Rapids permit and Rouge River RAP. Michigan's CSO Permitting Strategy stated that the following level of CSO treatment would be considered adequate treatment: retention for transportation and treatment at the WWTP, of combined sewage flows generated during storms up to the one-year, one hour storm; primary treatment of combined sewage flows generated during storms up to the tenyear, one-hour storm (thirty minutes detention or equivalent for settling, skimming and disinfection), and treatment of combined sewage flows generated in storms in excess of the ten-year, one-hour storm to the extent possible with facilities designed for lesser flows. Also very importantly, the Strategy provided that the permittee could demonstrate that other control methods would provide adequate treatment and meet water quality standards at the time of discharge. 1990 Milestone in Detroit WWTP Lawsuit Communities in the Rouge River basin contested the CSO controls in their NPDES permits. The parties entered a settlement agreement in 1991 to address CSO control. This agreement is often referred to as the Bulkley Agreement in recognition of the role played by the Court Monitor, Dr. Jonathon W. Bulkley. The Bulkley Agreement gave communities the option to demonstrate that alternative controls (alternative to the Department s definition of adequate treatment) could be pursued on a demonstration basis. The agreement was used as a main driver for securing Rouge River National Wet Weather Demonstration Project Grants in 1992. 1992 National Policy Formulated EPA assembled a stakeholder group to develop the framework for a national policy that would serve as the guiding principle for nation-wide CSO control efforts. The Department was very active in an initial stakeholder group and also in a subsequent group that formulated the basis for the national policy framework. 1992 Congress approved the Rouge River National Wet Weather Demonstration Project Rouge River Steering Committee Members: Ted Starbuck (SEMCOG), Kelly Cave (Rouge Program Office), Phil Sanzica (Oakland County Drain Commission), Janice Bobrin (Washtenaw County Drain Commission), Jim Murray (Wayne County Department of Environment), Dr. Jonathon Bulkley (Court Monitor), Paul Zugger (Department), Beverly Ingram (DWSD), Bob Beckley (City of Livonia), Paul Blakeslee (Department), Tom Biasell (Farmington Hills DPW Director) The southeast Michigan CSO control program received support from the federal government when Congress approved the Rouge River National Wet Weather Demonstration Project in 1992. Under this program, municipalities in the Rouge River Basin served as a pilot program to demonstrate the effectiveness of various CSO control 16
measures. The program also instituted a variety of other pollution control activities related to storm water discharges, stream bank erosion control, wetland preservation, public education and other measures. This demonstration helped secure significant amounts of grant funding for the design and construction of treatment demonstration basins to hold wastewater from wet weather events in various upstream locations. 1993 Michigan Law Amendment - Notification Requirements Michigan Law, PA 245 of 1929 was amended (by Public Act 29 of 1993) to require CSO release reporting by municipalities to assure appropriate notification for the purposes of advisories and public protection. 1994 Abolishment of the Water Resources Commission The Water Resources Commission was abolished in 1994 and its powers and duties were transferred to the Director of the newly formed Department of Environmental Quality. Act 245 of 1929, as amended, was codified as Part 31 (Water Resources Protection) of PA 451 of 1994, the Natural Resources Environmental Protection Act (NREPA). 1994 The Federal Government Adopted a CSO Policy EPA's CSO Control Policy, published April 19, 1994, is the national framework for control of CSOs. The Policy provides guidance on how communities with combined sewer systems can meet Clean Water Act goals in as flexible and cost-effective a manner as possible. EPA's Report to Congress on implementation of the CSO Control Policy assesses the progress made by EPA, states, and municipalities in implementing and enforcing the CSO Control Policy. The CSO Policy was published April 19, 1994, at 59 Fed. Reg. 18688. Since the Department was involved in formulating the national policy, the national policy somewhat mimics Michigan's program and includes the concept of treatment; but the national policy falls short of adopting Michigan's concept of adequate treatment by definition. 2000 Michigan CSO Systems Have Approved Long Term Control Plans. How Does Michigan's Program Compare to Other States? As part of its National Water Program Guidance for Fiscal Year 2006, EPA s Office of Water established the following target for CSO control: "By 2008, 75 percent of CSO permittees [sic. Nationwide] will have schedules in place in permits or other enforceable mechanisms to implement approved LTCPs." In Michigan, 100% of CSO permittees had schedules in place to implement LTCPs since 2001. Please note that the LTCP for the City of Detroit is a phased LTCP. Control programs to provide adequate treatment to meet water quality standards at times of discharge for the remaining 42 untreated CSOs (39 of these are to the Detroit River) with associated schedules are required in an update to the LTCP due by 12/1/08, according 17
to the NPDES permit. From this perspective, Michigan is at least seven years ahead of other states (taken as a whole) in terms of CSO control. 2000 Michigan Law Amendment - Release Reporting In July of 2000, MCL 324.3112(c) was added to the Natural Resources Environmental Protection Act, PA 451 of 1994, as amended. It required release reporting for partially treated and untreated releases and is the basis for development of Michigan's CSO & SSO annual reports. 2002 Michigan's Great Lakes Water Quality Bond Referendum The passage of the one billion dollar Great Lakes Water Quality Bond referendum in November of 2002 (Proposal 2) injected additional capital into the SRF, and created the Strategic Water Quality Initiatives Fund (SWQIF), which dramatically increased annual lending capacity for water quality protection efforts. What Does the Future Hold? Of the states that need to implement CSO controls, Michigan is far ahead of other states, yet work remains. Michigan communities have eliminated 75% of the CSO outfalls that existed in the year 1988 and the remaining 25% are scheduled for correction through implementation of LTCPs. While volumetric discharge data would be a better indicator of the environmental impact of Michigan s success, statewide data and estimates from the eighties and nineties are scant. One such estimate exists for the City of Detroit. The estimate provides an annual average untreated CSO volume of about 20 billion gallons per year in 1988. Based upon this figure the Department estimates that since submittal of Detroit s LTCP (in 1996) the City of Detroit has reduced the discharge of untreated CSO volume by about 85% (depending upon precipitation). The reduction has occurred even though only 12 of the 78 CSO outfalls have been addressed (efforts were targeted at corrections that provided the most return on the investment). Refer to Appendix 5 for more information regarding the status of the City of Detroit s LTCP. Facilities that are still implementing their LTCPs have projected funding needs. These projections show that we still have a long way to go in terms of time and costs to treat remaining untreated CSOs. These projections are summarized in the CSO Summary Table by Permittee. Based upon these projections, there is an estimated need for more than $2.875 billion for continuance of construction work on CSO projects (in 2007 dollars). Of that figure, Detroit accounts for $2 billion to $2.25 billion. Detroit has already spent over $704 million on CSO control and over the next 10 years they will spend an additional $1 billion. After that, they still have a projected funding need of 1 billion to 1.25 billion dollars. For more information about CSO control investments in Southeast Michigan, contact the Department's Warren district office. While SRF is the primary funding source for CSO work, it is not entirely reflective of how much money has actually been spent in Michigan to date. Where monetary data could be efficiently obtained, it was included in this report. Based upon suspected monetary expenditures from other sources (including bonds, demonstration grants, direct financing and other non-srf financing), it is estimated that Michigan communities have easily spent well over $2 billion in CSO control to date. 18

The numbers do not match because permits were categorized differently in the past. As remedies were pursued some permits were consolidated per treatment structure or remedy. In addition, based upon DEQ historical files, the communities of Milan, Stockbridge, Frankfurt, Hudson, Morenci, Jackson and Flushing may have addressed CSO issues since 1988. Outfall information is not easily available to confirm CSO information for these communities. 27
Wastewater Treatment How is Wastewater Treated? Sanitary wastewater treatment involves various stages; generally there is primary and secondary treatment, then a disinfecting stage. During the first stage, called primary treatment, 40 to 50% of the solids in the influent (wastewater from homes and businesses) are removed from the waste stream. The technology often used in the primary treatment stage includes bar screens (that remove trash), grit chambers (that slow down the flow to let sand, grit and solids settle and be removed) and sedimentation tanks (that allow particles to settle and be removed). During the secondary treatment stage, the treatment process continues to remove pollutants such that, following secondary treatment, 85 to 90% of the influent pollutants have been removed from the waste stream. One method of this type of treatment includes an aeration tank followed by a secondary sedimentation tank. In the aeration tank, air is mixed into the waste stream and microorganism concentrations are kept high to speed the consumption of the organic matter. In the secondary sedimentation tank, the microorganisms form clumps and settle to the bottom so they can be removed. After secondary treatment, a disinfectant such as chlorine is often used to kill disease-causing organisms before the wastewater leaves the treatment plant. Figure 4: Wastewater Treatment Process For more information on wastewater treatment technology, contact the federal Environmental Protection Agency s Publication Clearinghouse at 1-800-490-9198. Ask for a copy of the Primer for Wastewater Treatment, July 1980; document number 832K80100. This report summarizes the discharge events of untreated or partially treated sewage from sewer systems. Most of these discharge events are classified as CSOs or SSOs, which are discussed at length elsewhere in this report. Other types of events that are reported are from blending and bypassing. These types of discharges are discussed below. What is Blending? As a result of wet weather events, some WWTPs experience higher influent flows due to significant levels of infiltration/inflow (see definition on page 8) in the associated separate sanitary sewer system. In order to accommodate these higher influent flows in their wastewater treatment operations, some WWTPs have designed a blending option at their facilities ( blending used in this discussion does not include combined sewer systems). Generally during blending, the wastewater receives primary treatment and disinfection but a portion of the wastewater will not receive secondary treatment. The term blending generally refers to the 28
mixing of the wastewater that received full (i.e., secondary) treatment with a component of primary-treated wastewater that has been diverted around the secondary treatment process (see Figure 5, below). This mixed wastewater is disinfected and then discharged from the facility. Influent Secondary Treatment Effluent Primary Treatment Diverted Flow Disinfection Figure 5: Wastewater Treatment Process - Blending Condition The term blending is used specific to an anticipated wet weather treatment scenario approved by DEQ through issuance of a NPDES permit as a means to address higher influent flows as a result of wet weather conditions. Currently there are very few approved blending scenarios in Michigan. It is important to note that the discharges associated with these approved blending scenarios are required by the NPDES permit to produce effluent quality that complies with the Michigan Water Quality Standards (WQS). The DEQ periodically reviews these approved blending scenarios to determine the appropriateness of continuing these authorizations on a long-term basis. The DEQ expects that the number of approved blending scenarios in Michigan will be reduced to less than five in the future as infiltration/inflow continues to be removed from these systems. Although Michigan has a small percentage of facilities that have approved blending through an NPDES permit, in other states, up to 30 to 40% of facilities may engage in this practice under their NPDES permits. Data in Appendix 2 (pages B-1 and B-2) contains blended effluent discharges reported in 2007 for facilities with approved blending scenarios in their NPDES permit. There were 4 blending events reported in 2007 representing a volume of 64.88 million gallons. What is Bypassing? Bypassing is the diversion of waste streams from any portion of a treatment facility other than approved blending described above. Similar to blending, bypassing can be the result of elevated influent flows due to wet weather events. However, bypassing may occur in the absence of a wet weather event due to equipment failure or some other difficulties at the WWTP. In contrast to blending, bypassing is not a pre-approved treatment scenario and is not authorized in NPDES permits except to prevent severe property damage or loss of life. Further, unlike the approved blending scenarios, the discharges associated with bypassing events may or may not be compliant with the Michigan WQS. Instead, this wastewater is variable and often partially treated (usually through the treatment train up to the process unit that failed). For example, using the wastewater process shown in Figure 4, if a malfunction shut down the mechanical disinfection system, then the wastewater would have received secondary treatment (Figure 4) but not disinfection, and this would be considered a bypass. In general, the DEQ requires that the factors contributing to the occurrence of the bypass event be corrected as soon and as aggressively as is feasible. Data in Appendix 2 (pages B-3 to B-12) contains bypass effluent discharges reported in 2007. There were 14 bypass events reported in 2007 representing a volume of 407.43 million gallons. 29
Combined Sewer Overflows What are Combined Sewer Overflows and What Causes Them? Combined sewer systems are sewers that are designed to collect snowmelt, rainwater runoff, domestic sewage, and industrial wastewater in the same pipe. Most of the time, combined sewer systems transport all of their wastewater to a sewage treatment plant, where it is treated and then discharged to a water body. During periods of heavy rainfall or snowmelt, however, the wastewater flow rate in a combined sewer system can exceed the capacity of the sewer system or treatment plant. For this reason, combined sewer systems were designed to overflow occasionally and discharge excess wastewater directly to nearby streams, rivers, or other water bodies. Historically, CSOs were among the major sources for beach closings and other water quality impairments. How are CSOs Addressed? CSOs are a problem nationwide. Michigan initiated a CSO control program in 1988, and in 1994 the federal government developed a nationwide CSO Control Policy. This policy suggested that states use an enforceable mechanism, preferably the permit program that was initiated by the federal Clean Water Act (called the National Pollutant Discharge Elimination System) to require CSO communities to implement interim measures referred to as nine minimum controls by January 1, 1997, and to develop CSO Long-Term Control Plans (LTCPs). The nine minimum controls basically included interim measures that could be undertaken to improve the quality of the combined wastewater before major sewer system construction activities would be undertaken as part of the LTCP. Once the state and the community reached agreement on the LTCP, the community would then implement the CSO controls as soon as practicable. In Michigan, these LTCPs are contained in various legal documents including state issued NPDES permits, Administrative Consent Orders, Abatement Orders, and other legal documents. In Michigan, all municipalities with CSOs have completed the necessary interim control measures and have developed LTCPs. The LTCP must assess a range of control options, including costs and benefits, and lead to selection of an alternative that would achieve appropriate water quality objectives and compliance with the federal Clean Water Act and state laws. Since the cause of CSOs is the overabundance of rain or snow melt runoff entering the sewer system, many municipalities decide to separate their combined sewers, thereby redirecting the clean runoff to lakes, rivers and streams via storm sewers. Sewer separation projects are expensive and time consuming because they involve extensive utility and road reconstruction. Sewers typically run under roads; therefore, roads need to be torn up and re-paved in order to gain access to and re-direct the sewers. 30
While separating the sewer system is a common practice to eliminate CSOs, other communities may choose to build additional treatment or storage basins to contain a portion of the volume and provide adequate treatment of any resulting discharge to meet Water Quality Standards (WQS) at times of discharge. Specifically, as part of the final corrective program, many owners of combined sewer systems have installed or are installing treatment facilities for overflows, called retention treatment facilities (RTFs), which are designed to capture the combined sewage and runoff long enough to provide treatment and disinfection. Treatment often involves allowing solids to settle, the skimming of floatable materials such as sanitary trash and oils; and disinfection of disease causing organisms, often accomplished through the addition of chlorine. This is the typical treated CSO discharge in the State of Michigan. The treatment provided significantly reduces the amount of pollutants discharged. It is important to note that the fully implemented LTCP requires the permittee to provide adequate treatment that results in full protection of WQS and the Public Health. There are two different regulatory approaches related to review, approval and oversight of RTFs, namely presumptive and demonstrative. With the presumptive approach, the RTF is designed in a conservative manner where various established engineering criteria are met. In this approach, meeting WQS is assumed because of the conservative design and there is no need for a demonstration that WQS are met. Alternatively, sometimes economics preclude the building of such facilities because of the very large size, and instead the RTF is designed less conservatively, and therefore a demonstration will be required upon completion of construction to prove that discharges meet WQS. This later scenario is considered the demonstrative approach. Most RTFs in Michigan are designed following the demonstrative regulatory approach. What is the Main Challenge for Communities to Address in Controlling CSOs? Several challenges exist in controlling CSOs, the most significant being the costs associated with mounting wastewater infrastructure improvements and the financial resource-intensive nature of CSO controls. CSO LTCPs typically involve major infrastructure investments that compete with other community financial needs. There are several ways a community can fund CSO controls including federal grant programs and the use of bonds and user fees. However, the State The Department s Paul Blakeslee (former Field Operations Chief) Revolving Fund (SRF) has been Paul Zugger (former Surface Water Quality Division Chief) and Tom a major source of financial Kamppinen (Municipal Facilities, Grants and Loans) in front of an Oakland County CSO RTB as part of the Rouge Project (1994). assistance to communities addressing CSO problems and this involvement is particularly evident when reviewing the CSO Summary Report in the previous pages. This enhanced report summarizes SRF loans applied to CSO control projects within the State of Michigan. 31
Did We Make Progress in 2007? During calendar year 2007, ten CSO outfalls were eliminated as part of LTCPs. Dearborn eliminated three CSO outfalls, the City of Lansing eliminated two CSO outfalls and St. Joseph eliminated five CSO outfalls. Outfall elimination and/or treatment is not the sole indicator of progress in implementation of CSO control as extensive design and construction consistent with approved LTCPs is continuing in various areas of the State of Michigan. This includes large-scale sewer separation projects that are being conducted in the Cities of Grand Rapids, Lansing, and Port Huron; and large construction projects by the Cities of Detroit, Dearborn, Dearborn Heights, Inkster and others, to provide treatment and/or storage facilities for overflows to the Rouge River Watershed in Southeast Michigan. Continuing implementation, including design and construction of projects which occurred during calendar year 2007 will lead to elimination of or adequate treatment of CSOs in future years. What Data Does the Detailed CSO Report (Appendix 3) Contain? The data contained in the appended CSO Report was reported (as required by law) to the DEQ by the responsible parties. During the report period from January 1, 2007, through December 31, 2007, there were 296 CSO events reported for a total volume of 26,407 million gallons (i.e., approximately 26.4 billion gallons). It is noteworthy that almost half of this total volume (12,808 MG, or approximately 12.8 billion gallons) represents partially treated sewage that, in addition to settling and skimming, has been disinfected to protect the public health in compliance with the Water Quality Standard for discharges containing human sewage (i.e., R323.1062 of the Part 4 Rules). Of this partially treated volume, approximately 473 million gallons is defined as adequately treated, the associated facilities are designated with an asterisk below. 32

This report provides trend data through three measures; number of untreated outfalls eliminated per year, number of overflow events per year and volume of discharge per year. Michigan communities have eliminated 75% of the 613 untreated CSO outfalls that existed in the year 1988 and the remaining 25% are scheduled for elimination through implementation of LTCPs. On average, since 2003, there have been 8 outfalls eliminated or redirected to retention treatment facilities per year (Figure 6). 33
With respect to the number of overflow events, the number of 700 overflow events per past years 613 has been modified for this 600 report. In past reports, the cities of Dearborn and Detroit have 500 been reporting events in a more 400 specific manner than other municipalities with CSO 300 discharges. In past reports, each time an outfall discharged, it was 190 200 179 171 168 158 counted as an event. In 2007 both of these cities modified 100 their reporting. Generally, an event is now referring to the 0 Time storm that caused the discharge, Lapse 1988 2003 2004 2005 2006 2007 even if it is from multiple outfalls (so outfalls are grouped for the Figure 6: Number of Untreated Outfalls by Year purposes of counting an event). This is new reporting methodology is consistent with reports from other facilities. Staff went back to the past years data for these two entities and re-calculated events (Figure 7 captures the modified data). In 2007, there were 296 overflow events. This event data closely tracks the precipitation data (Figure 9). 450 400 350 300 250 200 425 395 398 150 328 323 342 296 100 50 0 2001 2002 2003 2004 2005 2006 2007 Figure 7: CSO Number of Reported Events/Year Total overflow volume rather than number of events is a more important indicator of success with respect to CSO control, because even a negligible volume of overflow triggers an event to be registered consistent with statute. Of course, levels of precipitation vary annually, which directly affects the total overflow volume. As with previous years, the total overflow volume for calendar year 2007 (26,407 million gallons, Figure 8), reflects the annual precipitation rates (Figure 9). However, as implementation of LTCPs continues in the State of Michigan, it is expected that the annual number of events and annual overflow volumes will demonstrate decreasing trends in both these categories. It should be noted that the component of the total 34
overflow volume that is the treated volume will increase in the coming years as the goal of many approved LTCPs is to provide adequate treatment of overflows to meet WQS. 40,000 35,000 30,000 25,000 20,674 20,000 13,600 Total CSO Volume Untreated 15,000 31,726 23,802 27,148 9,422 Partially Treated 10,000 19,354 16,648 5,000 10,342 12,808 0 2001 2002 2003 2004 2005 2006 2007 Figure 8: CSO Reported Volume (Million of Gallons)/Year 50 45 40 35 30 25 20 15 10 5 0 2001 2002 2003 2004 2005 2006 2007 Grand Rapids Lansing Detroit Figure 9: Annual Precipitation (Inches) for Various Michigan Cities/Year 35
Sanitary Sewer Overflows What are Sanitary Sewer Overflows? Sanitary sewer overflows, or SSOs, are discharges of raw or inadequately treated sewage from separate sanitary sewer systems. These systems are designed to carry sanitary sewage but not storm water. When an SSO occurs, sewage is released into areas such as the ground, streets and/or streams rather than being transported to a treatment facility. They are illegal and usually constitute a serious environmental and public health threat. Sewage discharges into basements may also occur, but these events are not required to be reported to DEQ for entry in this report under Section 324.3112(a) of NREPA. What causes an SSO? For the purposes of this report, SSOs can be categorized in three general categories, those being chronic SSOs, site specific SSOs, and SSOs due to mechanical/electrical failure or emergency. Chronic SSOs can occur when too much water enters into a sanitary sewer system. This water, known as clear water, includes, but is not limited to, the following sources: Ground water that seeps in through cracks in the sewer pipes; Rain water or snow-melt that flows into the sanitary system through improperly connected roof drains; Groundwater that enters from footing drains and sump pumps; and Storm water that enters when storm sewers are inadvertently connected to the sanitary sewer. Chronic SSOs can also occur when sanitary systems are too small to contain all the sanitary wastewater that is in the sewer system. Specifically, if the sewers and pumps that transport the sewage through the system are undersized, SSOs can result. Factors that can lead to chronic SSOs include: increased development in a community to the point where there is not enough sewer system capacity to handle the population; or system deterioration due to the age of the sewer system. Site specific SSOs occur when blockages in the sewer cause sewage to back up in the sewer system. Some examples of blockages include tree roots growing into the sewer, when a sewer partially or totally collapses, when sediments build up in the sewers, or when grease or trash block the sewer. Finally, SSOs occur due to power outages, emergency conditions, and equipment or mechanical failures. Examples include: faulty valves within the sewer pipes, lightening strikes to pump stations; the breaking of a sewer pipe; power failures that shut down pumps (which are installed to force sewage through the system), and even car accidents that damage sewer system pump stations. 36
How Does the Sewage end up in the Environment? Sewage may escape from a sewer system in many different ways. For example, SSO events include direct releases of sewage from a broken sewer pipe and releases of sewage through a manhole in the lowest area of the sewer system. Sometimes sewage has been intentionally released from a sewer system into the environment to prevent basements flooding within the system. Additionally, some sewer systems have emergency storage basins (often called equalization basins) that hold excess sewage in an overflow scenario. These basins can provide some treatment of the sewage, and in extreme rain events, unauthorized overflow releases of sewage may occur. How are SSOs Addressed? Since SSOs have different causes, there are various ways that SSOs can be addressed. When SSOs are a chronic problem in a community, DEQ will require the responsible entity to implement corrective actions within a defined schedule ( schedule of compliance ). The schedule of compliance will outline how the SSOs will be eliminated or adequately treated, and the schedule will be embodied in a compliance document. Frequently, DEQ works to achieve a voluntary settlement. These settlements are often embodied in documents called District Compliance Agreements, permits, or Administrative Consent Orders. If a voluntary settlement is not achieved, then a schedule of compliance will often be sought through litigation resulting in a court order or court judgment. For site specific SSOs caused by sewer blockages, the response is undertaken by the responsible entity. The response activity will usually include the removal of the sewer blockage to restore the proper function of the sewer system, along with cleanup and/or disinfection of the areas where sewage was spilled to limit public exposure. The emergency response for SSOs due to equipment failures are handled in a similar way. The power is restored or the mechanical problem is fixed (i.e. the cracked sewer is repaired, or the faulty pump is replaced); and the area is similarly cleaned up or disinfected. While this report is intended to provide the public with an overview of the issues surrounding SSOs and how they are addressed, other documents may be useful for professionals in the environmental field that would like to learn more about Water Bureau s policy in addressing SSOs. On December 27, 2002 a policy statement was issued and a subsequent clarification statement was issued on October 23, 2003. The policy statement was the result of consultation with a stakeholder group to develop guidance for implementing the May 2000 Strategy for the Regulatory Control and Correction of Illegal Overflows from Separate Sanitary Sewer Systems in Michigan. These documents can be found on our website www.michigan.gov/deqwater, select Surface Water then Sanitary and Combined Sewer Overflows. 37
What Factors Might Justify Longer-term Plans for Stopping Chronic SSOs? Sewer systems are frequently complex and expensive to fix. Consider that sewer pipes are buried with other utility lines, oftentimes under roads, making access to them difficult. This limited access not only makes repair difficult, but it also makes the identification of extra sources of water to the sewer system a challenge. In addition, many sewer systems were built over 30 years ago, are reaching the end of their design-life and are in need of rehabilitation or replacement. Additional costs could include engineering to design system improvements, upgrades to the WWTP to handle additional flow, and replacement of pumps and other equipment that make up the sewage system. Monies may or may not be available via grants, low rate loans or rate increases; therefore, many communities and private sewer system owners need time to secure funding. Sewer system owners usually need time to find the cause of large systemic problems such as identifying the sources of clear water infiltrating into the system or finding the components in the system that are undersized. In addition the system owners will need time to review financing alternatives, design construction improvements, and to implement the project. Did We Make Progress in 2007? The DEQ entered into four formal schedules of compliance addressing SSOs in calendar year 2007. These were with the cities of Northville, Plymouth, Westland and Garden City. In addition, an agreement was entered with the City of Grand Rapids that resolved violations associated with a December 2004 SSO discharge event and requires the submittal of an updated Emergency Response Plan. During calendar year 2007, $27 million in low interest loan funding was awarded through the State Revolving Fund to address SSOs. Assistance went to Genesee County for improvements to the regional sewer system tributary to the Anthony Ragnone Wastewater Treatment Plant, the city of Harbor Beach for the construction collection system improvements, including an equalization basin. In addition to the progress mentioned above, there was a great deal of other progress in 2007 to address SSOs (as required by compliance schedules). For example, the village of Almont completed a newly constructed storage basin to meet the remedial design storm of the DEQ s Sanitary Sewer Overflow Policy. The city of Trenton completed major upgrades to its sanitary collection system including pump stations and storage facilities. The charter township of Van Buren finished the construction of a sanitary sewer collection system equalization basin. Each of these construction projects will help reduce SSO discharges in the future. 38

In calendar year 2003 there was an electrical blackout (sometimes referred to as the Northeast United States Regional Blackout), lasting from August 14-16, 2003. This event impacted much of the southern portion of the State of Michigan. To minimize events due to electrical failure, Michigan WWTPs are required to have either dual direct power feeds from two independent electrical substations, or to have one direct power source and a standby generator. During the blackout, entire electrical grids went down. This event differed from past power outages. This event left the facilities that depended upon the two independent electrical substations without power and about 117 Million Gallons from 2003 can be attributed to this event. KEY TO THE REPORTED VOLUME CODES: In the Appendices, when a volume range was reported, the greatest value was used for the purposes of this report. In addition, volume totals were rounded off to a maximum of three decimal places, when applicable. The following codes mean: a = reported as an approximate value c = reported volume unit (e.g., cubic feet) converted to standard units (million gallons) g = reported volume greater than or equal to listed value l = reported volume less than or equal to listed value 46

Appendix 5 Status of the Detroit Long-term CSO Control Plan (LTCP) The City of Detroit continues to make significant progress implementing the LTCP that was submitted in 1996, with approved elements first embodied in the 1997 NPDES permit. Revisions to LTCP projects were made and further included in the 2003 NPDES permit, and again in the 2007 NPDES permit. Detroit s LTCP has initially focused on 1) bringing as much wet weather flow to the WWTP during events and treating it to NPDES required primary levels (some treated through full secondary treatment as required by EPA CSO policy), 2) using insystem storage in the combined collection system (large flat sewers are available for storage), and 3) by storing/treating priority CSOs on the collection system using RTBs, etc. The 2007 NPDES permit requires that an updated LTCP be submitted by December 1, 2008 that defines the correction projects and associated schedules for the remaining untreated CSOs in Detroit. These specific correction projects and associated schedules will be incorporated into the NPDES permit once approved (either through modification or at the next reissuance). The MDEQ requires that all CSOs be corrected to provide adequate treatment to meet all water quality standards at times of discharge. The State of Michigan does not use less restrictive wet weather water quality standards nor are permittees allowed the option of use-attainability analyses to downgrade designated uses of receiving waters. MDEQ District staff is participating in the DWSD meetings where this updated LTCP is currently being developed. Significant progress includes completion of: 4 CSO Storage/Treatment Facilities along the Rouge River. These include the Seven Mile RTB (2.2 MG), the Puritan Fenkell RTB (2.8 MG), the Hubbell-Southfield RTB (24 MG), and the Baby Creek Screening & Disinfection Facility (screens and disinfects all CSO flow ~5000 cfs peak), 3 CSO Storage/Treatment Facilities along the Detroit River. These include the Conner Creek RTB (30 MG), the Leib Screening & Disinfection Facility (screens and disinfects all CSO flow ~1500 cfs peak), and the St. Aubin Screening & Disinfection Facility (screens and disinfects ~250 cfs peak), 6 in-system storage gates at CSO outfalls along the Rouge River (interim control until completion of the Upper Rouge Capture Tunnel), 13 in-system storage devices within the collection system. These are inflatable dams in large sewers. 11 of the 13 are in combined sewers that are tributary to Detroit River CSOs, and 2 are in combined sewers that are tributary to the Baby Creek CSO Facility, additional facilities at the WWTP(i.e. 2 180 MGD primary clarifiers, an additional influent pump in PS 2) that have increased its ability to treat combined wet weather flows to primary treatment levels as required by the NPDES permit (capacity now 1.7 billion gallons per day (BGD) as compared to 1.2 BGD prior to submittal of the LTCP), Rehabilitation of pump stations and regulators along the Detroit River, Completion of the instrumentation/control system that determines CSO flows and discharge times for the remaining untreated CSOs. This instrumentation and control system also has many other functions for both the wastewater system and water system. 1
Completion and several revisions to collection system hydraulic model used for LTCP planning, and specific project design. Additional projects with established NPDES schedules of compliance: construction of the >201 million gallon Upper Rouge Tunnel (URT) by 2013 (will control 17 Detroit and 11 suburban CSOs), construction of the 9 MG Oakwood CSO RTB and pump station by December 1, 2010 (will control one CSO), construction of the 0.3 MG Belle Isle CSO Treatment Facility by March 1, 2008 (will control one CSO), and completion of additional control facilities for five CSOs in the lower Rouge River by August 1, 2012. Completion of the second Detroit WWTP Outfall to the Detroit River (DRO-2, outfall 084A) by December 31, 2011. Currently, wet weather flow discharged from the RRO (outfall 050A to the Rouge River) is treated using preliminary and primary treatment, but is not disinfected. Completion of the DRO-2 will allow all excess wet weather flow to be fully disinfected and dechlorinated. The wet weather flow discharged out the DRO-1 (049A through outfall 049F to the Detroit River) is treated using preliminary and primary treatment and currently receives full disinfection and dechlorination. Note that the last 30 days of discharge from 1) 050A averaged 37 mg/l TSS, 16 mg/l CBOD 5 and 0.9 mg/l T. Phosphorus, and 2) 049A averaged 48 mg/l TSS, 23 mg/l CBOD 5, and 1.1 mg/l T. Phosphorus. Estimate of reduction of untreated CSO due to LTCP: The Department estimates that since these current controls have been completed less than 15% of the previously discharged untreated CSO volume (annual average of about 20 billion BGY before submittal of the LTCP) remains, though to date 12 of the 78 CSOs have been addressed. Established correction projects will by 2013 further eliminate two untreated CSOs once construction currently underway is completed, 17 untreated CSOs once the URT project is completed (plans now in-house for final construction permitting), and an additional five untreated CSOs (for a total of 36 of the 78 CSOs). It is estimated that the cost of LTCP controls through 2013 will be approximately 1.1 billion dollars. Note that CSO volume is highly dependent upon annual precipitation. In 2006 for example, over 32 billion gallons (BG) of wet weather flow were discharged by Detroit. This value exceeds that typical annual average discharge level due to a wet 2006 (42 of precipitation vs. 32 in an average year). Note that, as described above, most of this 32 BG was treated to NPDES levels either at the WWTP or at CSO Storage/Treatment facilities, with only a smaller portion discharged as untreated CSO.
