As a result of the task force, the Met Council will implement an ongoing inflow and infiltration mitigation program in 2013. The Council sets a million gallon per day peak flow discharge threshold by metershed based on a ten- year average flow. This flow is reportedly adjusted to consider additional flow generated from growth. In 2011 the City's threshold for peak flow was 1.52 MGD, the 2012 threshold is set at 2.18 MGD. Any excessive flow over the 2.18 MGD threshold will require the City to respond to the Met Council with I/I mitigation efforts in 2013. Overall the City does not have an I/I problem; however in July 2011 the City did exceed the 1.52 MGD threshold albeit very briefly. If this occurs in 2012, the Met Council reports the City will either pay a fine of roughly $375,000 per MGD over the threshold, or OPH could submit a work plan for Met Council approval distributing that same amount over a four (4) year period to mitigate any I/I issues.

Design plans for constructing a monitoring point shall be submitted to the Regional Administrator for approval 60 calendar days prior to any construction necessary to meet the criteria specified in this section. All new installations shall be in accordance with provisions of the Minnesota Plumbing Code, Minnesota Rules, chapter 4715. Each permittee is responsible for all maintenance on the approved monitoring point, including routine cleaning. MCES Waste Discharge Rules Page 13 212.02 Inspection Maintenance Hole. The Regional Administrator may require the installation of an inspection maintenance hole (manhole), in the event of any construction, replacement or modification of a permittee's sewer connection(s). Permittees shall provide notice to the Regional Administrator prior to any such replacement or modification. The inspection maintenance hole shall be of standard size and shape, and be located on the private sewer line between the facility and the public sewer. If feasible, the inspection maintenance hole shall convey the total facility wastewater discharge. The inspection maintenance hole may serve as a permittee's monitoring point provided all provisions of Section 212.01 are met. 212.03 Representative Sampling. Representative samples shall be collected by permittees at an approved monitoring point. Sampling shall be conducted on a normal operating day and in accordance with standard monitoring techniques described in Section 213.00. The samples shall accurately characterize the discharge, taking into account batch discharges, daily production variations, downtime, cleanup and other operating conditions. Each permittee shall accurately determine wastewater flow volumes during periods of sample collection. Sample compositing shall be flow proportional unless specified otherwise by the Regional Administrator. 212.04 Volume Determination. Wastewater volumes discharged by permittees to public sewers shall be determined during sampling periods using metered water supply or wastewater flow measuring devices or both. Use of water meters for sampling period wastewater volume determinations shall comply with requirements of Section 215.00. When hourly water meter volumes do not correlate with monitoring point hourly wastewater volumes, hourly wastewater volume measurements at the monitoring point may be required. The installation and operation of flow measuring devices shall be in accordance with requirements and methods in Sections 213.00 and 215.00. 212.05 Monitoring Requirements for Non - permitted Industrial Users. Representative sampling and volume determination requirements, applicable for permit applicants and other persons utilizing public sewers for the disposal of industrial waste, shall be determined by the Regional Administrator. Such requirements shall conform to Sections 212.01 to 212.04 whenever feasible. 213.00 Monitoring Techniques This section describes monitoring methods to be used by industrial users and contracted monitoring services and/or commercial analytical laboratories who collect and/or analyze wastewater samples to fulfill requirements of these rules or any permit issued under these Page 14 MCES Waste Discharge Rules rules. Monitoring methods specified in this section include sample collection, preservation, handling, analysis, and flow measurement. 213.01 Grab and Composite Samples. Samples shall be collected as specified in the permit or as determined by the Regional Administrator. Grab and/or composite samples may be required. A. A series of at least four grab samples is required when analyzing wastewater for pH, grease and oil, total phenols, and sulfides. Samples for cyanide and volatile organics may be collected by the grab sampling procedure described above or by an automatic sampler, using acceptable techniques. For other parameters, grab samples may be required when the wastewater flow is not continuous or when necessary to determine the instantaneous wastewater characteristics. Grab samples can be taken manually or automatically. Appropriate containers shall be used when collecting grab samples. B. Composite samples are formed by combining discrete samples collected either manually or by an automatic sampler. Each discrete sample shall have a minimum volume of at least 100 milliliters. Discrete samples can be composited using any of the following methods: (1) equal time intervals and equal volume samples; (2) equal time intervals and unequal volume samples; or (3) unequal time intervals and equal volume samples. When an equal time interval method is used, the maximum sampling interval shall be 30 minutes. The composite sample volume shall be well mixed before subsampling. 213.02 Required Sampling Methods. Samples shall be collected in a well -mixed region of the wastewater. In order to avoid collecting nonrepresentative amounts of sediment or floating material, the intake of the sampling device shall be placed appropriately. When using an automatic sampler, the intake line velocity shall be sufficient to ensure representative sampling of suspended solids. The minimum intake velocity should be two feet per second. The minimum automatic sampler intake line inside diameter shall be one -fourth inch. When feasible, the automatic sampler intake shall be downstream of any primary flow device. 213.03 Sample Handling Procedures. All samples shall be contained, preserved and held in accordance with 40 CFR part 136. The sample temperature shall be maintained at 4 degrees Celsius, if necessary, from the time of collection until sample analysis is performed. When applicable, additional preservation shall be performed upon sample collection. MCES Waste Discharge Rules Page 15 213.04 Wastewater Flow Measuring. The following requirements apply to the selection and installation of wastewater flow measuring devices: A. Flow measuring devices including, but not limited to, weirs, flumes, area - velocity sensors and closed -pipe flow meters, shall be installed such that proper hydraulic conditions exist.

Box 2007 Stillwater, MN 55082 -3007 RE: 2013 Ongoing Inflow /Infiltration (I /1) Program Peak Hourly Discharge Thresholds Dear Mr. Kegley On January 1, 2012 the Metropolitan Council will begin measuring and reporting peak hourly flow exceedances to your community as part of its ongoing III program. Any exceedances that are measured within your community between January 1. 2012 and June 30. 2012 will require a response frcm your community relative to 1/1 mitigation efforts beginning in 2013. Details regarding the Council's ongoing 1/I program were previously forwarded to your community and can also be found on the Council's web site at: hrtp ://www.metrocouncil.org/ environment /ProjectTeams /1- 1- I- Iome.htm As specified in the Council's Demand Charge Task Force Report, peak flow discharge thresholds will be based on ten -year average flow by metershed adjusted to 2011. Adjustments to the ten -year average shall consider additional flow generated by growth and I/1 mitigation efforts within the ten -year average flow period. The Council has reviewed your community's flow records and has assigned the following adjusted average and peak hourly flow thresholds to the metershed(s) within your community: Adjust. Avg. Threshold Metershed (MGD) (MGD) M607 0.66 2.18 These peak flow thresholds are valid for the initial flow period between January 1, 2012 and June 30, 2012, Also specified in the Task Force Report was an adjustment for potential I/I in regional facilities which are located within a community. These adjustments are currently being determined and will be applied to peak exceedances if they occur. Your c5. w \'' community may or may not qualify for this adjustment as it is dependent on whether or not your community has any c L O.‘ regional interce ptors located within it. The Council will be scheduling a community 1/1 workshop for sometime in February 2012. Specific details regarding this workshop will be forwarded to you in the near future. Please contact Kyle Colvin at (651) 602 -1151 or kvle.colvin ametc.state.mn.us if you have any questions or require additional information regarding the Council's ongoing I/1 program, the commencement of peak flow exceedance monitoring starting January 2012, or the upcoming I/I workshop.

Infiltration . ublicly occurs when groundwater seeps into sewer pipes through. ; 1 owned sewer cracks, leaky joints or deteriorated manholes. The far.. ..., Cracked pipe or open larger problem, however, is inflow. sewer Joint Inflow occurs in direct proportion to rainfall. The typical source is water from rain leaders, basement sump pumps (designed to capture water that enters basements) or foundation drains illegally connected directly to a sanitary sewer pipe. A sump pump can contribute 7,200 gallons of clear water to the wastewater system in 24 hours, the equivalent of the normal daily flow from 26 homes. This clear water entering wastewater pipes consumes capacity in the system needed for future growth in the region. For example, during a heavy rainstorm, the normal 200 million gallons a day (mgd) of wastewater flowing to the Metro Plant in St. Paul can more than triple to 700 mgd or more. Excess clear water is also a financial burden on residents, since the Council charges communities for the amount of wastewater they contribute to the treatment system. More than half of the region's 103 sewered communities currently show a significant response to rainfall events. The updated Water Plan details how the Council will work closely with communities to reduce I/I to reasonable amounts so that the system continues to have adequate capacity to serve future growth. The Council will: • Establish I/I goals for all communities discharging wastewater into the metropolitan disposal system. • Require communities served by the metropolitan disposal system to include an I/I reduction program in their comprehensive plan. • Potentially limit increases in service to communities with ongoing excessive I /I. • Starting in 2007, institute a surcharge program to provide funding for I/I reduction efforts. • Starting in 2013, institute a demand charge for communities that do not meet their I/I goals. Another policy change is that the Council will consider acquiring and operating local wastewater treatment plants in rural growth centers where the community requests it and enough growth is projected to make Council involvement economically feasible. The plan establishes criteria whereby the Council can evaluate such requests, and also outlines circumstances where the Council might share the costs of system improvements with local communities. • • • • • • • n source po ution — ur.at gency estimates that more than 90 percent of the pollu urce controls alone cannot adequately begin to address ater management section of a community's local compt t source pollution, the Council could find the local pla "system impact," would require modification °of the lo ship with local governments, watershed organizations, a -duce nonpoint source pollution, including: e region's lakes, rivers and streams. •artners institute best management practices that reduce aintain or improve water quality. shed management plans, local surface water manageme is to ensure that communities are fulfilling their nonpo -fore reducing the impacts on the region's wastewater sy Jointed by the governor.

The Offices of Administration and Financial Management and Planning provide expertise in finance and administration specific to the needs of MCES customers, employees and partners. Both offices provide project coordination with the Council's Regional Administration department. I Financial Overview MCES is a user -fee based organization, which is run as an enterprise. Revenues MCES revenues include volume -based Municipal Wastewater Charges (MWC), industry- specific charges, Sewer Availability Charge (SAC) and miscellaneous revenues. MWC account for most of the revenues and are determined by a utility -like rate that reflects the cost of providing service based on the volume of use. This charge is a Revenue /Sources wholesale charge that MCES allocates 1 to its 105 customer 5.5% 1.9% communities (listed, 9.8% l pg. 21).

Labor includes all staff costs including salaries, wages and benefits. 3. Non -Labor includes costs for utilities, chemicals, materials and supplies and contracted services. 4. Interdivisional Charges are mostly labor costs allocated to MCES for shared Council Central Services (like Human Resources) and shared governance expenses. 2011 Annual (Operating) Budget The 2011 operating rate is approximately $2,026 per 1 million gallons (or $203 per 100,000 gallons) of treated wastewater. The cost allocation is based on actual system -wide flows from June 2009 through June 2010 of 85.3 billion gallons. 2011 • Municipal Wastewater Charges = 172.8 • SAC Transfer = 20.4 ti p • Industry-Specific Charges = 11.5 Char Revenue rY-S pec� g • Other = 6.5 :es • TOTAL Revenue = 211.2 ($ in millions) 2011 ! • Debt Service & PAYG = 93.5 • Labor = 59.7 Expenses/ • Non - Labor = 48.3 • Interdivisional = 9.7 Uses • TOTAL Expenses = 211.2 About MCES 1 7 The MCES budget process includes collaboration with the MCES Management Team and Regional Administration staff, as well as municipal and industrial customers. The result is financial planning that incorporates funding for new and existing programs essential to goals of the Council and MCES and its customers. The MCES budget is incorporated into the Council's unified budget and approved every December. MCES 2011 Capital Budget The 2011 capital budget, which consists of the project expenses for all of the active projects in the capital program, is $142 million. Capital planning takes place at several levels. • Long -range master plans have been developed for the interceptor system and treatment plants. These master plans are updated periodically to reflect the most recent demographic forecasts and impacts from local comprehensive plans, federal and state regulations and permits, and other relevant factors. These plans have been incorporated into the 2030 Water Resources Management Policy Plan, which also contains policies and strategies for efficiently and effectively addressing pollution from point sources and non -point sources (runoff) to achieve regional water quality goals. • Facility plans evaluate alternative solutions for specific projects, recommend facilities and estimate costs and timing, and evaluate the impacts of a project. During project implementation, projects are delivered through one of two procurement options: 1. Public ownership and financing: using a design- bid -build procurement. 2. Public ownership and financing: using a design -build procurement.

A lift station in St. Paul is one of 62 in the metro -wide system The infrastructure includes: • Almost 600 miles of interceptor (or 11 I sewer) pipes, which range in size from 6 inches to 14 feet in diameter I I • 62 lift stations, which pump wastewater toward the treatment plants row • 188 meter stations, which measure each �"""� community's flow and help determine each community's cost share The interceptor network is closely monitored by a sophisticated computerized telemetry system that provides continuous data and monitors the status of MCES facilities, flow meters and regulators. Data is transmitted to the Regional Maintenance Facility (RMF) in Eagan. m•rsr. Dispatchers staff RMF 24 hours a day, 7 days a week, 365 days a year. Interceptor Services employees work at and out of the Eagan facility mow and the Mounds View and Mound lift stations. Larger lift stations, like the one pictured above, process higher volumes of wastewater daily About MCES 1 10 wow - Treatment Services w Treatment Services provides overall operation eFm and maintenance of the system's wastewater treatment plants. Treatment Services is the largest of the four MCES departments; it comprises 55 percent of all MCES employees. Treatment Services is organized into seven business units: 1. Metro Plant Liquids 2. Metro Plant Solids Management 3. East (includes Empire, Eagles Point, Hastings, St. Croix Plants) 4. Seneca 5. Blue Lake 6. Maintenance and Security (serves all treatment plants) 7. Support Services (serves all treatment plants) Metro Plant Liquids Business Unit This group is responsible for two basic stages in wastewater treatment: primary and secondary. In the primary stage, solids are allowed to settle and are removed from the wastewater. The secondary stage uses biological processes to further purify the wastewater. Metro Plant Solids Management Business Unit This group processes solids that are removed during the liquids treatment stages. After separating as much liquid from the solids as possible, the solids are processed in fluidized -bed incinerators. The resulting ash is disposed of in a landfill. Heat recovered from the incinerators produces steam that helps heat the plant and produces enough electricity to meet about 20 percent of the plant's power demand. In 2006, the Solids Management Building (SMB) earned a National Environmental Achievement Award from the National Association of Clean Water Agencies (NACWA). The award cited the successful planning, design, construction, and operation of the facility. In addition, the Minnesota Public Works Association presented MCES with a 2006 Project of the Year Award for this new state -of -the -art facility which has dramatically reduced air emissions, energy usage, and costs since beginning operation in 2004. About MCES ) 11. East Business Unit, Seneca Business Unit, Blue Lake Business Unit These groups work in various capacities (at six plant sites listed previously) to provide quality service to all communities and customers in the metro area not served by the Metro Plant. Maintenance and Security Business Unit This group provides service and technical guidance to all MCES facilities in support of short- and long -range operating plans. Employees in this unit — electricians, machinists, painters, pipefitters, warehouse workers, security specialists and maintenance operators— maintain MCES's assets. Support Services Business Unit This group provides technical support throughout the Treatment Services Department.

About MCES 12 Awards MCES wastewater treatment plants continue to perform at a high level in complying with clean water discharge permits. In 2011, all MCES plants earned Peak Performance Awards from the National Association of Clean Water Agencies (NACWA) for their performance in 2010. The NACWA Platinum Awards represents five or more consecutive years of full compliance with clean water discharge permits. The Hastings and St. Croix Valley Plants are among the top 10 plants in the country in this regard. Through 2010, Hastings had 20 consecutive years of full if compliance, St. Croix had 19, Seneca had 10, Blue Lake had 5, and Eagles Point had 5. The Empire and Metro Plants earned Gold Awards for perfect compliance for the calendar year. Through Wastewater exiting the final stage of treatment February 2011, all seven treatment plants combined have been in full permit compliance for 49 consecutive months. • +� ��i. In addition, all seven treatment , plants received Certificates of Commendation from the Minnesota Pollution Control Agency (MPCA) for their — performance in 2010.

Operation of the new Solids Management Building (SMB) began in 2004. �_ SMB includes three fluid -bed incinerators, t. .. dewatering equipment, and energy recovery and pollution- control systems. SMB processes about 240 dry tons of solids per day. The fluid -bed incinerators are more energy efficient and produce cleaner air emissions than the previous technology utilized at the plant. Energy from the hot incineration gases is converted to steam in waste -heat boilers. The steam is used to heat plant buildings or to power a turbine generator to meet some of Metro's electrical demand. In addition, completed plant odor control projects w have greatly reduced the number of complaints , irk ; 111 from the Metro Plant's neighbors.
