General Manager’s Office (Administration, Financial Management and Planning, Safety, and Contracts and Procurement)

The General Manager’s Office includes staff for Administration, Financial Management and Planning, Contracts and Procurement, and Safety. The Offices of Administration and Financial Management and Planning provide expertise in finance and administration specific to the needs of MCES customers, staff and partners. In addition, both offices provide coordination with the regional administration departments of the Metropolitan Council.

Financial Overview. Resource allocation decisions are driven by the Council’s policy and plans and MCES’s performance objectives that align with those plans. MCES is a user-fee based organization, which is run as an enterprise. The Council’s rate-setting philosophy is that user classes should each pay their “cost of service.”

Revenues include the volume-based municipal wastewater charge, industry-specific charges, service availability charges (SAC), and miscellaneous revenues. Municipal wastewater charges account for 75.4 percent of total revenues and are determined by a utility-like rate that reflects the cost of providing service based on the volume of use. This rate is a wholesale rate that MCES charges to its customer communities. The communities charge their residents (customers) a retail rate that is specific to their city and covers their administrative and infrastructure costs.

Expenses fall into three major categories. The largest, debt service, includes costs of infrastructure planning, design, construction and rehabilitation. Labor is the second largest and includes all staff costs including salaries, wages, and benefits. The third category, non-labor, includes costs for utilities, chemicals, materials and supplies, and contracted services. MCES’s revenue and expense categories are represented in the following graphic.

MCES’s 2007 Annual (Operating) Budget. The rate for the 2007 operating budget is approximately $152.6 per 100,000 gallons of treated wastewater. The budget is based on actual systemwide flows from June 2005 to June 2006 of 95.6 billion gallons. Budgeted revenues and expenses for 2007 are shown in the following table:

MCES’s 2007 Operating Budget ($s in millions)

Total Revenue $193.6 Total Expenses $193.6

The MCES budget process includes interaction with the MCES Management Team, Regional Administration staff and municipal and industrial customers. The result is financial planning that incorporates funding for new and existing programs essential to the goals of the Council, MCES and our customers. MCES’s budget is incorporated into the Council’s Unified Budget and is approved in December of each year.

MCES’s 2007 Capital Budget. The 2007 capital budget, which consists of the project expenses for all of the active projects in the capital program, is $127 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 2005 Water Resources Management Policy Plan. The Policy Plan 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.

Finally, during project implementation, projects are delivered through one of two procurement options:

Public ownership and financing: using a design-bid-build procurement.

Interceptor Services Department (Maintenance, Operations, Metering/Alarm, Interceptor Engineering, and Fleet Management)

Metro-area homes and industries are connected to MCES’s treatment plants through an extensive network of sewer pipes. Each community in the Twin Cities metropolitan area maintains the sanitary sewer pipes from homes or industries; these sewer pipes connect to regional “interceptor” sewers. MCES’s Interceptor Services Department operates and maintains the infrastructure necessary for the collection and transport of wastewater from 104 community sewer systems to the eight MCES-operated wastewater treatment plants. The infrastructure includes approximately 600 miles of interceptors, which can be up to 12 feet in diameter; 61 lift stations, which pump the flow to keep it moving toward the treatment plants; and 190 meter stations, which measure the flow from each community and help determine each community’s share of cost.

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 dispatch center in Eagan. Dispatchers staff the center 24 hours a day, 365 days a year. Interceptor Services’ staff work at and out of the Regional Maintenance Facility in Eagan and the Mounds View and Mound lift stations.

Treatment Services Department (Six Business Units: Metro Plant Liquids, Metro Plant Solids Management, East, Southwest, Maintenance and Security, and Support Services; and Eight Treatment Plants)

The Treatment Services Department provides overall operation and maintenance of the system’s wastewater treatment plants. About 260 million gallons of wastewater are treated daily at the eight regional plants. Treatment Services is the largest of MCES’s four departments; approximately 75 percent of the staff positions are budgeted in this department.

The department is organized in six business units. Because of its size and complexity, the Metro Plant is divided into two business units: Liquids and Solids Management. The East Business Unit includes five plants: Empire, Rosemount, Eagles Point, Hastings and St. Croix Valley. The Southwest Business Unit includes Seneca and Blue Lake. The remaining two business units —Maintenance Services and Support Services — serve all eight plants.

The Metro Plant Liquids Business Unit is responsible for two basic stages in the treatment of wastes: 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. In the Metro Plant’s liquids process, these stages are combined into one operation.

The Metro Plant Solids Management Business Unit processes sludge produced by the Liquids Business Unit. Solid waste is created from the liquid sewage by separating as much liquid from the solids as possible, creating sludge cakes to be processed by incineration. Ash, a by-product of this process, is stored and loaded into trucks for private contractors who service the concrete industry. This business unit also produces and distributes the steam used to heat all parts of the Metro Plant.

Barely into its second year of full operation, the new Solids Management Building earned a prestigious “2006 National Environmental Achievement Award” from the National Association of Clean Water Agencies (NACWA). The award, in the operations category 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.

The East Business Unit and Southwest Business Unit work in various capacities (at seven plant sites listed on the previous page) to provide quality service to all communities and customers in the metro area not serviced by the Metro Plant.

The Maintenance and Security Business Unit provides service and technical guidance to all of MCES’s facilities in support of short- and long-range operating plans. Staff in this unit (electricians, machinists, painters, pipefitters, warehouse workers, security specialists, and maintenance operators) proactively maintain the assets of the division.

The Support Services Business Unit provides technical support throughout the Treatment Services Department. Staff in this unit include engineers, environmental scientists, computer system specialists and administrative support personnel.

Award-Winning Treatment Performance NACWA Awards: In early 2006 MCES was awarded several Peak Performance Awards from the National Association of Clean Water Agencies. The organization represents the nation’s 300

largest wastewater collection and treatment utilities and their more than 500 treatment plants. The Seneca Plant heads the list this year, earning a Platinum Award for achieving five consecutive years (2001–2005) of full compliance with clean water discharge permits. This is the second platinum award for the Seneca Plant which registered full compliance from 1994 through1998. Plants earning Gold Awards for full compliance during 2005 were Empire, Hastings, Metro, Rosemount and St. Croix Valley.

MPCA Awards: The Minnesota Pollution Control Agency recognized six treatment plants for outstanding operation, maintenance and management from October 2004 through September 2005. The Empire, Hastings, Metropolitan, Rosemount, St. Croix Valley and Seneca Plants earned certificates of commendation at the annual MPCA awards program in March 2006.

The following pages provide information on the treatment plants and the areas they serve. More information on business units and plants can be found on MCES’s Intranet and Internet sites.

Metropolitan Wastewater Treatment Plant

Built in 1938 near Pig’s Eye Lake in St. Paul, the Metro Plant was the first wastewater treatment plant in a major city located on the Mississippi River. It is the largest treatment facility in Minnesota and is among the nation’s largest, treating an average of 185 million gallons per day (mgd) of wastewater from 65 communities and 617 industries. About 75 percent of the wastewater generated in the Twin Cities metropolitan area is treated at the Metro Plant.

The Metro Plant utilizes the activated-sludge process for treating wastewater to an advanced secondary treatment level prior to discharge to the Mississippi River. A very high level of ammonia, phosphorus and other conventional pollutants are removed. Sludge is processed by thickening, chemical and/or thermal conditioning and high-pressure or centrifugal dewatering prior to incineration. Ash from incineration is transferred off-site for beneficial use. Energy recovered as steam in the waste-heat boilers is used to heat buildings, to thermally condition sludge, or to power steam turbines.

The plant has an excellent environmental record and regularly earns state and national awards for operational excellence (refer to the award information on pages 8 and 9).

Originally designed as a primary treatment facility to treat an average flow of 134 million gallons of wastewater per day, the plant has been expanded four times and upgraded to its current advanced secondary treatment level with chlorination/dechlorination.

A major upgrade to the Metro Plant was completed in 2004 which included full biological phosphorus removal capability, state-of-the-art solids processing and air emissions control technology, energy recovery systems, and rehabilitation of the pre-treatment and primary facilities. Operation of the new Solids Management Building began in 2004. The building includes three fluid-bed incinerators, dewatering equipment, energy recovery and pollution-control systems, and a process for preparing up to 10 percent of the solids to be safely applied to agricultural land. The building processes about 220 dry tons of solids per day.

In addition, completed Metro Plant odor control projects have greatly reduced the number of complaints from citizens in the plant neighborhood.

Information on upgrades and projects at all eight of the treatment plants can be found in MCES’s Capital Improvement Plan (CIP) and MCES’s Summary Budget. These documents are available from the Council’s Data Center or on MCES’s Intranet and Internet Web sites.

Empire Wastewater Treatment Plant

Built in 1979, the Empire Plant, located in Empire Township, provides wastewater treatment for five communities in the southeast metro area. The facility serves a population of 134,000 and treats an average of 8.5 mgd. The facility is a two-stage, activated sludge plant followed by effluent filtration to provide advanced treatment and ammonia removal. Recent construction has increased the plant’s capacity from 12 mgd to 24 mgd, which will accommodate the rapidly expanding growth in the current and future service areas. The sludge from the plant is thickened, anaerobically digested and dewatered, stored onsite, and then spread on farmland. Empire Plant Statistics Located in: Empire Township Type: Advanced secondary with ultraviolet disinfection Capacity: 24 million gallons/day Discharges to: Vermillion River Communities served: 5 Population served: 134,000 Interceptors to plant: 16 miles

Recognizing that doubling the discharge of treated wastewater to the small, environmentally sensitive Vermillion River could harm the river, the Council has chosen to pump treated wastewater through a new 13-mile pipe being built from the Empire Plant to the Missisippi River in Rosemount. This pipe, along with a new interceptor to convey wastewater from the current Rosemount Plant to the Empire Plant, is scheduled for completion in 2008. At that time, MCES will close the Rosemount Plant, the smallest of eight in the system.

Rosemount Wastewater Treatment Plant

The Rosemount Plant is MCES’s smallest facility, treating an average of 800,000 gallons per day. Built in 1973, the plant was operated in cooperation with the U.S. Environmental Protection Agency as a demonstration project using a physical/chemical treatment process. That process proved inefficient, and in 1989 the plant was rebuilt and expanded using conventional biological treatment—an aerated pond system. Secondary treatment is provided with effluent discharged to the Mississippi River. Solids production is minimized in the aerated pond process; removal of slowly accumulating sludge inventory is provided for on a periodic basis. The facility serves most of the city of Rosemount and received a Gold Award from NACWA in 2006 for full compliance with clean water discharge permits in 2006. Rosemount Plant Statistics Located in: Rosemount, Minnesota Type: Aerated ponds with UV disinfection Capacity: 1.4 million gallons/day Discharges to: Mississippi River Communities served: 1 Population served: 7,000 Interceptors to plant: 8 miles Due to growth in this service area, MCES will close the plant in 2008 and convey flow to the Empire Plant through a new interceptor. This interceptor is being built concurrently with the 13-mile outfall pipe that will convey effluent from the Empire Plant, through Rosemount to the Mississippi River. Meanwhile, interim improvements completed in 2003 have increased the plant capacity from 0.84 million gallons per day to 1.4 mgd. The plant treats an average of 1.0 mgd.

Eagles Point Wastewater Treatment Plant

Located in Cottage Grove overlooking the Mississippi River, the Eagles Point Plant began service in September 2002, replacing the old Cottage Grove Plant that had been in operation since 1962. The new treatment plant has a capacity to treat 10 million gallons of wastewater per day. It provides primary and secondary treatment to wastewater before discharging it to the Mississippi River. Biosolids are processed and applied to farmland or transported to the Metro Plant in St. Paul for treatment.

The plant’s capacity should be sufficient to serve the growing area until approximately 2030, at which time it could be expanded to 20 million gallons per day. The plant’s liquid treatment facilities opened in the fall of 2002 and the solids treatment facilities opened in fall 2003. Ten miles of interceptors to the plant began service in 2005, which increased the flow to be treated from an average of 2.2 mgd to 4.2 mgd.

In 2006, the Eagles Point Plant earned a Gold Award from NACWA for permit compliance during 2005 (refer to awards information on page 9).

Hastings Wastewater Treatment Plant

Located in the city of Hastings along the Mississippi River, the Hastings Plant earned a national NACWA Gold Award in 2005 for perfect compliance with clean water discharge permits (see page 9 for more award information). It serves about 20,000 residents in Hastings, treating an average of 1.6 million gallons per day before discharging to the Mississippi River.

Hastings Plant Statistics Located in: Hastings, Minnesota Type: Advanced secondary with chlorination/dechlorination Capacity: 2.9 million gallons/day Discharges to: Mississippi River Communities served: 1 Population served: 21,000 Interceptors to plant: none

The original Hastings Plant was built in 1955. The plant was expanded and renovated between 1983 and 1986 at a cost of $8.3 million; 75 percent of this amount was provided by the Federal Government and 15 percent by the State of Minnesota. Odor control for the aeration tanks was added in 1989. The Hastings Plant utilizes biological treatment technology. Biosolids are transported to the Metro Plant in St. Paul for treatment and beneficial use.

Designed to treat an average wastewater flow of 2.9 million gallons per day, the plant will reach the end of its useful life by about 2015. A new site on the eastern edge of the city has been acquired and planning has begun for building a new plant.

Technical Services Department (Engineering Services, Drafting and Records, and Construction Services

MCES’s Technical Services Department provides services that support the Council’s mainte-nance and capital projects. Department staff may work on any number of projects including projects financed out of both MCES’s operating and capital budgets. Staff are located in one of three business sections: Engineering Services, Construction Services, and Drafting and Records.

Engineering Services provides for the long-range capital planning activities and the development, production, and administration of MCES’s Capital Improvement Program and Capital Budget. Capital planning staff also coordinate projects funded through the State Revolving Loan Program, and provide research and special studies to support department objectives and responsibilities. MCES’s 2007 capital budget is $127 million (as shown on the right). Of the $127 million, 49 percent is earmarked for expansion, 45 percent for rehabilitation and 6 percent for quality improvement. Quality improvement projects include phosphorus removal at the Blue Lake, Seneca and Empire Plants.

Engineering Services provides project management and in-house design for MCES’s wastewater treatment facilities operation and maintenance and capital improvement projects.

Drafting and Records’ basic function is to provide, support, and maintain Computer Aided Drafting and Design (CAD) within the organization. This includes development of CAD standards, policies and procedures and contract language as well as preparation and maintenance of engineering bid design documents.

Construction Services provides construction contract administration and inspection services for MCES’s operation and maintenance and capital improvement projects, and for Metro Transit’s capital projects. Staff are located at the Metro, Seneca, Empire and Blue Lake plants.

Environmental Quality Assurance Department (Industrial Waste/Pollution Prevention, Analytical Services, Environmental Monitoring/Water and Air Quality, Research

and Development, Environmental Compliance, Water Resources Assessment, and Water Supply Planning) MCES’s Environmental Quality Assurance (EQA) Department provides leadership and technical services for the development and implementation of environmental plans and programs for the metropolitan area. EQA also provides technical and regulatory services to the Metropolitan Council and works with other organizations to ensure that plans and programs are cost effective and are focused on regional goals. Staff work in the administrative, or special projects area (which provides a variety of resources in customer and community relations, communications and environmental education to serve MCES’s internal and external customers) or one of the following seven sections:

The Industrial Waste/Pollution Prevention (IWPP) Section manages use of the MCES system by industrial users and other discharge sources to protect wastewater facilities, operating personnel and the environment. Major functions include administration of Industrial Discharge Permits, enforcement of regulations, monitoring, and response actions. Staff also promote pollution prevention and provide technical assistance to customers to reduce volume and pollutant loadings into the system.

The Analytical (Laboratory) Services Section provides customers with quality, timely, and cost-effective technical services. These technical services include: project development; sample

analysis; sample collection and container preparation; instrument quality assurance; test method development; data reporting; and information management.

The Environmental Monitoring/Water and Air Quality Section has two areas of business: Water Quality and Air Quality. Following the standards

in the Water Resources Policy Plan, staff monitor the water quality of regional rivers, streams, lakes, and wastewater treatment plant discharges. Water quality problems are identified, management decisions are made for improving and protecting water resources, and achievement of water quality goals are measured. The Air Quality area provides for air testing services requested by MCES. Staff evaluate point source emissions, site specific air zones, and ambient air, at and around MCES facilities.

21

Research and Development conducts research and gathers information that provides advice and assistance in making informed decisions related to current and future problems, treatment processes and methods for achieving air and water quality objectives, and the impact of agency actions on the environment.

Environmental Compliance ensures that all MCES facilities have the environmental permits and licenses necessary to operate within mandated guidelines. Staff in Environmental Compliance are responsible for submitting applications for environmental permits, negotiating permit conditions, tracking permit and regulatory requirements, and monitoring regulatory developments of federal and state environmental programs. In addition, staff provide environmental expertise to the entire MCES division by advising staff on regulatory requirements impacting projects and activities, providing technical and regulatory support for recycling and sustainability activities, and administering MCES’s Environmental Audit Program.

The Water Resources Assessment Section provides technical information for Council actions on environmental matters. It also provides assistance in developing, coordinating, reviewing and implementing these actions. Water Resources Assessment staff are involved in environmental protection and management, including: technical assistance for watershed planning; environmental review; nonpoint source pollution control research; regional water supply planning; target pollutant loads development; grant coordination; and, other natural resource studies.

The Water Supply Planning Section was created early in 2006 in response to legislation that increases MCES’s role in regional water supply planning. Initially, staff is developing a base of technical information and a regional water supply master plan, clarify the responsibilities of various levels of government and provide staff support to the Metropolitan Area Water Supply Advisory Committee.
