NPDES Storm Water Permit Annual Report City of Saint Paul June 1, 2001 The City of Saint Paul submits this report in fulfillment of the annual reporting requirements of the NPDES Storm Water Dischazge Pernut MN 0061263 issued to the City of Saint Paul on December 1, 2000. This report satisfies the criteria set forth in Pernut Section 2.18. Storm Water Management Program The proposed storm water management program to be implemented in 2001 is included as Appendix A. The cost benefit analysis of individuai BMPs will be submitted in the 2002 Annual Report. Inventory Storm Sewer Outfall Inventorv Saint PauPs storm sewer outfalls are found in Appendix B. This listing includes the outfall identification number and the size of the outfall pipe. Drainage azea, land use, population, percent impervious and number of structural controls will be provided for Saint Paul's watersheds in the 2002 Annual Report. Figure 1 shows Saint Paul's watersheds. The Department of Public Works is actively developing a computer based asset and infrastructure management system. This system will include both the storm and sanitary sewer networks. A contract is currently being awarded to obtain City-wide, LIDAR generated, 1 foot digital contour mapping. When the asset and infrastructure management system is complete, we will have the data and systems necessary to accurately detemune the sub-watershed for each of the outfalls. This, in conjunction with other existing data sets such as land use and zoning, will allow us to determine the inventory information by outfail. The estimated time line for the systems and products discussed is two to three years. Storm Water Pond Inventorv Saint Paul's storm water ponding areas aze constructed to collect and detain flows from storm events. These ponds aze designed to reduce peak flow rates in downstream storm sewers. Figure 2 shows the storm water ponding areas in the City of Saint Paui. Tributary azea, land use type and distribution, population and design capacity for each City ponding azea will be provided in the 2002 Annual Report. _ � o�_co� , x . �• � m � , az� -.

Storm Water Monitoring and Modeling .Toint MonitoringProgram The Cities of Saint Paul and Minneapolis and the Minneapolis Park and Recreation Board aze participating in a joint storm water monitoring program as required by the storm water permit. Minneapolis Park Boazd staff will be conducting the monitoring program for the three year pernut term. The Storm Water Monitoring Program Manual was completed by Minneapolis Park Boazd staff and submitted sepazately to the MPCA in April of 2001. This manual is incorporated by reference. A copy of the joint monitoring agreement will be submitted to the MPCA after signatures are obtained from all three parties. The five-yeaz budget for the joint monitoring program is included in Appendix D. Sampling sites are identified in the Storm Water Monitoring Program Manual. The sampling sites were selected from the sites used in the storm water permit application monitoring program. Five sites were chosen, representative of the following land use types: two residential sites, two industriaUcommercial sites, and one mixed use site. Two sites are located in Minneapolis with three in Saint Paul. Saint Paul sampling sites are located on Figure 3. A snow melt and a rainfall event was collected in April of 2001. Monitoring results for the 1994 storm water pernut application monitoring program are found in Table 1.

Currently, the river is monitored to measure the effecriveness of wastewater treaunent processes, measure compliance with water quality standards, and identify pollution sources. Agencies involved in Mississippi River flow and/or quality monitoring include the Metropolitan Council, U.S. Geological Survey, MPCA, Hennepin County, and the Corps of Engineers. Monitoring data for the Mississippi River is summarized by sections or reaches and miles of the River. The first of these reaches (#401) extends from the Minnesota River to the Metropolitan Wastewater Treatment Plant. Reach #401 is partially supporting for swimming and supporting, but threatened for aquatic life. A Fish Consumption Advisory for PCB's and mercury applies to this reach. The impact of the Minnesota River is significant through this reach. The Minnesota River Basin Project involves efforts to reduce nonpoint source pollution through coordination among multiple units of government and citizens. The Mississippi River from the Ford Dam to Hastings has become a nationally recognized fishery as a result of water quality improvements and a catch-and-release policy. The river is also becoming increasingly utilized for recreation. Metro�olitan Council The Metropolitan Council does routine river water quality monitoring at two stations in Saint Paul. These are L.ock and Dam No. l, located above the Ford Dam, and Saint Paul, located at 7ackson Street and Lambert's Landing. The data is from 1994 - 1998 and contains conventionai pollutant monitoring and toxics data. Table 2 is a summary of this water quality data. Table 2: Mississippi River Mean Water Quality Values 1994-1998 Source: Met Council ot-Cob Minnesota Pollution Control Aeencv The Minnesota Pollution Control Agency monitors reach #401, Mississippi River above the Metro Wastewater Treatment Plant, sampled at the Minnesota Rowing Club dock upstream of the Wabasha Street Bridge in Saint Paul. A monitoring station at reach #402, Mississippi River above Saint Anthony Falls, sampled at the Minneapolis Waterworks intake at Fridley, provides additional upstream water quality information. Reach #201 is located above Lock and Dam #2 in Washina onlDakota County. This site provides data on water quality below the Metropolitan Waste Water Treatment Plant and as the river meets up with the St. Croix River downstream of Saint Paul. These sites are sampied monthly by the MPCA. Table 3 shows the Mississippi River Mean Water Quality Values from 1986 to 1996.

The subwatershed is 1,786 acres in size and land uses include a public golf course, zoo, pazklands, residential housing, and a few higher density shopping areas. Runoff from the golf course is routed through a series of two constructed ponds prior to entering Como Lake. Discharge from the lake enters into the Trout Brook Stortn Sewer, and ultimately discharges into the Mississippi River. Gottfried's Pit, located upstream of Como Lake, collects drainage from 549 acres including intercommunity flow from Roseville, Faicon Heights> Ramsey County right-of-ways, and St. Paul. The pond has a pumped outlet to Como Lake with a maacimum capacity of 3200 galions per minute. Como Lake average summer water quality is summarized for the period 1982-2000 in Table 4. Growing season sampling is done by the Ramsey County Lake Management Program on a yearly basis. Profile sampling in the deepest azea of Como Lake is done at least 6-8 times during the May through September. In addition to chemical measures of water quality, biological samples are collected for analysis of phytoplankton abundance and composition, crustacean zooplankton, and aquatic plant community composition. Como Lake is a biologically productive shallow lake. Even so, water quality has fluctuated over the monitoring period. Long-term plots (1982-2000) of secchi depth, total phosphorus and chlorophyll-a are shown in Figures 4, 5 and 6. This lake is considered to be hypereutrophic. b �-CO� Table 4: Como Lake Water Quality 1982 - 2000 _ Year '' ;Secclu.(n►) TP Cmg/m') CCHL(mglm'). =- 1982 0.65 219 67.7 1984 0.60 190 9$•7 1985 0.50 225 101.0 1986 1.10 310 38•� 1987 2.70 186 7.8 1988 2.00 137 24.6 1989 2.00 152 24•7 1990 0.90 198 493 1991 0.80 224 43.9 1992 1.20 152 26•8 1993 2.20 108 21•g 1994 1.70 121 29.0 1995 1.40 255 51.2 1996 1.20 276 57.6 1997 1.20 141 37.6 1998 3.20 104 9•Z 1999 3.20 ll2 11.3 2000 2.08 133 19.6 Source: Ramsey Co.

Two major projects included: 1) Biomanipulation and aeration Ramsey County received an EPA Clean Lake grant to evaluate phosphorus loads and water quality in Como Lake. Implementarion strategies included biomanipulation, which consisted of removal of rough fish by the DNR using the chemical rotenone and aigal control in 1985, followed by restocking of largemouth bass, bluegili and walleye in 1986 and implementation of fishing restriction on lazgemouth bass. Macrophyte harvesting was initiated 'an the period following the fisheries renovation and has been done during several subsequent yeazs. Also in 1985, a partial air-lift aeration system was installed to limit winter fish kilis. 2) Renovation of the Como Lake Golf Course that included the diversion of some inflows to �onds within the golf course. The renovation of the Como Lake Golf Course included the addition of several ponds to the course in 1987. Storm water runoff from three major storm sewers entering the north end of Como Lake (which contribute about 85% of the annual surface water budget for Como Lake) were partiaily diverted to two new sedimentation ponds in the golf course. A 1982 study, (Runke) concluded that there were three water quality problems in Como Lake: 1. High levels of nutrient input which leads to increased algae levels and decreased transparency; 2. Hypolimnetic oxygen depletion and subsequent sediment phosphorus release (internal loading}; and 3. An imbalance of the biology of the lake. Monitoring since the eaziy 1980's indicate water quality in Como Lake follows a cyclic pattern, as measured by water transpazency or secchi depth. The onset of the cyclic changes in water quality in Como Iake is related to the biomanipulation or fisheries management completed in 1985. This biomanipulation activity manipulates the food chain and the cycles appear to reflect nature's way of adapting to these changes. At one point in September 1986, visibility in Como Lake extended to the bottom in the deepest portion of the lake. \ A 1998 report (Noonan) on the water quality changes in Como Lake identified three factors \ which aze important to the observed water quality `cycle' and also future management strategies. � �', l. The amount of phosphorous in Como Lake drives the biological productivity, or energy level, in the system. 2. Daphnia directly affect the abundance of algae in Como Lake, which triggers the observed cyclic trend in water transpazency. 3. Macrophtyes provide valuable habitat for fish, Daphnia, and other biota and also provide a possible mechanism to reduce the abundance of algae in Como I.ake. 10 ��-CO� Lake Phalen Lake Phalen has a surface azea of 198 acres, a masimum depth of 91 feet and a mean depth of approximately 24 feet. The drainage azea is 1822 acres and land uses inciude a public golf course, parklands, residential housing, and a few commercial azeas. Lake Phalen is a meso/eutrophic lake even through annual phosphorus and water loads are chazacteristic of eutrophic lakes. It appears that the physical structure of L,ake Phalen provides a significant water quality buffer. The depth of the lake basin provides for extremely stable thermal stratification during the summer, which effectively separates the upper and lower portions of the water column. Nutrient export processes from the upper part of the water column during the summer aze very important because the nutrients lost to the bottom layer aze unavailabie to algae unUl the fall mixing period. Algae abundance remains quite low through the summer as a result, particulariy in dry summer periods. L,ake Phalen's average summer water quality is summarized for the period 1987-2000 in Table 7. Growing season sampling is done by the Ramsey County Lake Management Program on a yearly basis. Long-term plots of secchi depth, total phosphorus, and chlorophyll-a are given in Figures 7, 8 and 9.

When repairs, improvements, or changes aze planned for existing flood control devices, the City will evaluate the feasibility of retrofitting the existing devices to provide additional poliutant removal from storm water dischazges. The City will also report in each annual report the number and type of flood control projects planned and describe the poilutant removal capabilities associated with each project. Figure 2 in the Annual Report shows the storm water ponding areas located in the City of Saint Paul. 1.4 Removed Substances (Perrrrit 2.6) 'The disposal, handling and recording of removed substances will be addressed as part of the foilowing sections of the Storm Water Management Plan: 1.6 Storm Water Pond Maintenance 1.7 Catch Basin Pilot Project 2.1 Street Cleaning and Maintenance 3 ��-to� 1.5 Outfalls (Permit 1.2.1 & 2.4.5) A lisi of the City of Saint Paul storm sewer outfalls aze found in Appendix B. Twenty percent of the cities 102 permitted outfalls or 20 outfalls will be inspected each year beginning in 2001. Erosion protection will be provided as necessary based on an ouflet inspection. Erosion protection will be completed during the same year as the inspection or a schedule for completion will be submitted in the annual report. Results of outlet inspection will be included in the annual report, including the dates of inspection and the date of completion of additional erosion protection. ax o Bridal Veii Creek 1 Mississippi River 66 LTpper Lake 2 Crosby Lake 2 Fairview North Pond 2 Lake Como 11 I.oeb Lake 1 Lake Phalen 6 Beaver Lake 2 Suburban Ave. Pond 2 Little Pig's Eye Lake 1 Pig's Eye Lake 2 Battle Creek 4 Total Discharge Points 102 � 6�-�0` 1.6 Storm Water Ponding Areas (Pernut 2.4.1- 2.4.2) The City will operate and maintain all storm water structural conuols in a manner so as to reduce the dischazge of pollutants. The City will inspect all storm water ponds a minimum of two times per year. The City will also keep records of inspection results, date, antecedent weather conditions, sediment storage and capacity remaining, and any maintenance performed or recommended. After two years of inspections, if patterns of maintenance become apparent the frequency of inspections may be adjusted. If maintenance or sediment removal is required as a result of both inspections the freguency o£ inspection shall be increased to at least three times per year or more frequent if needed to prevent cazry-over or washout of pollutants from the structures and maximize pollutant removal. If maintenance or sediment removal is not required as a result of both inspections, the frequency may be reduced to one time per yeaz. Figure 2 in the Annual Report shows the storm water ponding azeas located in the City of Saint Paul. 1.7 Catch Basin Pilot Project (Permit 2.43 - 2.4.4) The City will conduct a catch basin pilot pmject according to the following schedule: Scheduie Select study area Clean all catch basins in area Monitor accumulation (monthly) Clean catch basins as required Final Report July to September 2001 October to November 2001 March 2002 through October 2003 March 2002 through October 2003. 7anuary 1, 2004 5 01-�4� 2. Roadwavs The responsible department is Pubiic Works Street Maintenance. 2.1 Street Cleaning and Maintenance Program (Permit 2.81 & 2.8.2) The City of Saint Paul conducts a street cleaning program to promote the health and welfare of its citizens and to reduce the amount of pollutants to receiving waters from storm water discharges. Streets and alleys are divided into six classes, each of which receives a different level of service as defined below: Class I- Downtown or Loop streets The following service is performed on all downtown or loop streets within the following boundaries: Kelloag Boulevard on the south and west, Twelfth Street on the north and Broadway Street on the east. These streets are swept approximately three times per week and flushed five times per week during the spring, summer and fall. All rourine maintenance, including patching and repairing of street surfaces, is performed on an as-needed basis. Class II - Outlying Commercial and Arterial Streets These streets are the major arteries in the City and have both heavy volumes of vehicular and pedestrian traffia These streets also have business or commercial properties fronting on them. Typical examples aze: University Avenue, Snelling Avenue, West Seventh Street, East Seventh Street, Rice Street, Payne Avenue, Arcade Street, Summit Avenue and Grand Avenue. The Ciass II streets are swept or cleaned fifteen to eighteen times in annually. All routine maintenance, including patching and repairing of street surfaces, is done on a scheduled or as-needed basis. Class III - Residential Streets The following service is performed on all residential streeis including oiled, paved and intermediate type streets. In the spring, all residential streets receive a thorough cleaning which includes sweeping and flushing. Patching and repairing is done on a scheduled or as-needed basis. Street Maintenance initiated the foilowing policy in August 1997: Oiled streets aze seal coated on a five-year cycle until the oiled street is scheduled to be paved as part of the Residential Street Vitality Program. The street is then be added to the ten- year cycle seal coat list. All existing paved streets are on the ten-year cycle seal coat list. Approximately 12 miles of oiled streets and 60 miles of paved streets were seal coated in 2000. Oil and sand sealing of oiled streets is no longer done. Tn 1995, a recycling program was initiated for all reclaimed sand and seal coat rock. These materials are no longer hauled to the landfill. In the fall, streets are swept for leaf pickup. All material swept up during this fall cleanup is hauled to a commercial composting facility. o�-c.o� Class IV - Oiled and Paved Alleys All oiled and paved alleys are swept during the late spring. Ail routine maintenance, including patching and repairing of the alley surfaces, is performed on a scheduled or as-needed basis. Street Maintenance initiated the following policy in August 1997: Oiled alieys are seal coated on a five-yeaz cycie. Paved alleys are seal coated on a ten-yeaz cycle. Oil and sand sealing of oiled alleys is longer done. In 1995, a recycling pro�ram was initiated for ali reclaimed sand and seal coat rock. These materials aze no longer hauled to the landfill. Class V and VI - Unitnproved Streets and Alleys Unimproved streets and alleys aze right-of-ways that have not been developed. There are approximately 50 miles of unimproved streets and approximately 288 miles of unimproved assessed alleys in the City. Because they are City right-of-ways, the City has the responsibility to perform minimal repairs and maintenance work on them to make them passable and to reduce hazards. The maintenance and repair of these streets and alleys consists of patching, minor blading, and placing of crushed rock or other stabilized material. Debris Collection In 2000, the sweepings collected from city streets and alleys were tested and found to be within EPA guidelines for safe disposal in landfills and for recyciing purposes. The following approximate volumes were removed from City streets in 2000 based on vehicular measure. Class I,II � IV Totals General Debris 7,164 cu.yds. 3,336 cu.yds. 1.392 cu.yds. 11,892 cu.yds. Leaves (Fall Cleaning) 4,354 cu.yds. 12,922 cu.yds. 0 cu.yds. 17,276 cu.yds. o�-co` Street Maintenance has a Hazazdous Waste Disposal Policy in piace. Any of these materials collected from city streets are disposed of in environmentally acceptable means. Street Maintenance also collects trash receptacles and disposes of refuse from neighborhood cleanups each year. The following is the street cleanina and maintenance budget for 2001: 2001 Street Cleaning & Maintenance Budget 2.2 Downtown 5treet Repair & Cleaning Outlying Commercial & Arterial Street Repair and Cleaning Residential Street Repair & Cleaning Oiled & Pave ailey Repair & Cleaning Trash Receptacle Pickup Neighborhood Cleanup Total Deicing Operations (Permit 2.83 - 2.8.5) $383,327 $2,848,243 $3,569,476 $1,683,246 $296,954 $132,896 $8,914,142 Deicing operations are weather dependent. Better ice control is obtained with salt above 0°F. Sand is necessary below this temperature. Deicing is done on arterial streets first and then on residential intersections after piowing. The City has been using less sand in recent years because of the effectiveness of salt at warmer temperatures, wanner winters, and the increasing expense of sand removal from streets. The City has experimented with liquid deicing products and has not found a effective alternative to salt. The City will continue to evaluate alternative products and report the findings in the following years, annual report. Salt piles aze covered year round. Sand and salt mixture piles are stored in the open from December to February. The City does not store sand/salt mixture during the remainder of the yeaz. Salt storage facilities are located in the following locations: 873 N. Dale Street 5�' Street and Kittson Street Pleasant Avenue & View Street QuanUty of deicing materials used will be reported starting with the 2002 Annual Report. a�-co6 3. Storm Water Management Ordinance The responsible departments are Pubiic Works Sewer Utility and License, Inspection and Environmental Protection. 3.1 Storm Water Management Ordinance (Permit 7.1- 7.3) The City will adopt a Storm Water Ordinance which meets the requirements of this section by June 1, 2003. The ordinance wiil include sediment and erosion control and long term storm water management requirements. A status report on this process will be given in the 2002 Annual Report. 3.2 Desi� Manual (Permit 2.7.4) The City is working with the parties listed below to develop a Small Site Urban BMP Manual. Barr Engineering is the consultant working on this project. The manual is in draft format and is scheduled to be completed in August of 2001.

Pesticides and Fertilizers (Permit 2.10.1- 2.103) The responsible departments aze Public Works Sewer Utility and Parks and Recreation. The City will implement a program to reduce the discharge of pollutants related to the application of pesticides and fertilizers. This will be accomplished through coordination with existing efforts, such as WaterShed Partners, the education program and the pilot project to investigate use on City facilities. 4.1 City Wide Education Program Component of 6.0 Public Education Program 4.2 Pilot Project City facilities that use fertilizer and pesticides on a regular basis, such as the golf courses, have procedures that are followed. This pilot project will document current city procedures including soii analysis to determine application amounts and rates. Investigate and document fertilizer and pesticide use on City Facilities Submit final report July 2001 through September 2003 January 1, 2004 � bl-Go� 5. Illicit Dischar�es and Improper Disposal The responsible department is the Public VJorks Sewer Utility. 5.1 Prohibit Non-storm Water Discharges (Permit 2.11.1, 2.113 & 2.11.5) The City will develop an ordinance defining proper discharges to the storm sewer system by January 1, 2QQ4. 5.2 Duty to Notify and Avoid Water Pollution (Permit 2.11.4, 3.8) The City will notify the Minnesota Department of Public Safety Duty Officer immediately of a discharge, accidental or otherwise, which may case pollution of waters of the state. Beginning with the 2002 Annual Report, the City will report the number of spills and unauthorized discharges that occuned and the response to the spills. T'he City will also implement an education program for its staff regazding the duty to notify the Department of Public Safety Duty Officer. The education program will include a notification protocol for maintenance staff in other department for response and containment of materials. 5.3 Field Screening Program (Permit 2.11.2) The City will implement a program to detect, remove, or require to obtain a separate NPDES or other permit illicit dischazges and improper disposal into the storm sewer system under its jurisdiction. An ongoing field screening program wil] be implemented which is similar to the program required in the pernut application. The program wil] be performed annually in 20% of the drainage azeas listed in the description on page 3 of the permit. The number of screening activities, the results, and responses to the results will be reported annually beginning in the 2002 Annual Report. 5.4 Allowable Non-storm Water Discharges (Pernut 2.11.6) The education program for non-storm water dischazges is a component of Public Education Program found in Section 6.0 of this plan.. 10 O�.�o6 6. Public Education Program (Pemut 2.10.2, 2.11.6, 2.13 & 2.16) The responsible Department is the Public Works Sewer Utility. Copies of educational materials, description of the education activities, and the quantity of material distributed will be included in the 2002 Annual Report. Storm Drain Stenciling Education Program The City of Saint Paul has been conducting a successful storm drain stenciling education program since 1993. For the past severai yeazs the Friends of the Mississippi River (FMR) has coordinated this program. FMR is the leading cirizens' organization working to protect the Mississippi River and its watershed in the Twin Cities area. The storm-drain stenciling project is designed to meet the following three objectives: • To stencil storm drains with the message "Please Don't Pollute—Drains to River," and distribute educational door-hangers to residents and businesses in the stenciled neighborhoods. • To involve community residents in hands-on learning experiences about urban runoff pollution and ways to prevent it. • To facilitate school service leaming initiarives that include storm drain stenciling as a key component. Project Components: • Identify and organize approximately 1,200 volunteers to stencil at least 2,800 storm drains and distribute 12,000 door hangers within the City of St. Paul during each year of the project. • Provide a 30-minute educational orientation to eacA volunteer group that participates in the stenciling project. • Provide an additional one-hour lesson on urban runoff pollution with school students that participate in storm drain stenciling (approximately 40-50% of the 1,200 volunteers). • Provide a training workshop for St. Paul teachers on storm drain stenciling and water quality classroom activities that complement the service project. • Present three community workshops for city residents on urban runoff pollution and ways to prevent it. • Develop and implement an evaluation system to deternune project effectiveness. • Coordinate the purchase, maintenance and storage of all stenciling supplies and equipment. • Project staff will generate publicity for at least two stenciling groups or events each year. Metropolitan daily newspapers, TV news and community press will be targeted. 11 ot-c.oa • FMR will develop a system to evaluate the effecriveness of participating in stenciling. A pre and post test will be implemented with a variety of groups and a summary of results will be distributed to WaterShed Partners and other interested groups. • Set-up, staff and take-down the WaterShed Exhibit at the St. Paul Department of Public Works Open House in September 2001. Project Budget The total cost for the 2-year project is $54,500. The following is the detailed budget for the two-year program: 2001 Budget 2002 Budget Stencil Coordination Service LearninglEducation Evaluation Community Workshops Teacher Workshop/Support Project Management Equipment and Supplies 13,290 3,300 1,200 0 0 2,000 1,930 12,750 3,300 600 1,800 7,400 3,000 3,930 Annual Totals Project Total $21,720 $32,780 $54,500 In addition to this budget, a Met Council grant is providing funding in 2001 for the community workshops, teacher training, door hangers and some supplies. Metro WaterShed Partners Saint Paul is an active participant in Metro WaterShed Partners. This group consists of municipalities, nonprofit groups, and state, federal and local government. This partnership has leveraged grant dollars and staff time to develop educational literature and a nationally recognized interactive display. The display is now being used at schools and events throughout the Twin Cities metro area. This partnership ailows Saint Paul to tap into a pooi of expertise and to not reinvent the wheel in its own pro�am. It also provides consistency in the message that the community is hearing. St. Paul's participation in this partnership shows a good faith effort in meeting current and future requirements and has allowed the City to maximize the staff time and dollars conuibuted. In 2001, the City contributed staff time and $2,000 to the annual operating budget of the WaterShed Partners and toward purchasing a van to transport the WaterShed Exhibit. 12 O!-LO6 7. Coordination with Other Governmental Entities (Permit 2.16) The responsible department is the Public Works Sewer Utility. 7.1 The City will submit a report listing the other govemmental enfities that perform storm water management activities in the drainage area. The report will include a summary of each activity performed by more than one group in a specific area, and how the activity relates to the requirements of the pernrit. This report will be submitted by June 1, 2002. 7.2 The City will submit a report that describes how the different governmental enrities are cooperating and coordinating efforts in managing storm water related activities in the drainage area. The report will include the goals for each cooperative effort, where and how the activity will be performed, and a schedule for implementing it. This report will be submitted by June 1, 2003. Ongoing coordinated activities and status of cooperative efforts will be reported in each subsequent Annual Report. 13 �1-co� 8.

NPDES Storm Water Permit Annual Report City of Saint Paul June 1, 2001 The City of Saint Paul submits this report in fulfillment of the annual reporting requirements of the NPDES Storm Water Dischazge Pernut MN 0061263 issued to the City of Saint Paul on December 1, 2000. This report satisfies the criteria set forth in Pernut Section 2.18. Storm Water Management Program The proposed storm water management program to be implemented in 2001 is included as Appendix A. The cost benefit analysis of individuai BMPs will be submitted in the 2002 Annual Report. Inventory Storm Sewer Outfall Inventorv Saint PauPs storm sewer outfalls are found in Appendix B. This listing includes the outfall identification number and the size of the outfall pipe. Drainage azea, land use, population, percent impervious and number of structural controls will be provided for Saint Paul's watersheds in the 2002 Annual Report. Figure 1 shows Saint Paul's watersheds. The Department of Public Works is actively developing a computer based asset and infrastructure management system. This system will include both the storm and sanitary sewer networks. A contract is currently being awarded to obtain City-wide, LIDAR generated, 1 foot digital contour mapping. When the asset and infrastructure management system is complete, we will have the data and systems necessary to accurately detemune the sub-watershed for each of the outfalls. This, in conjunction with other existing data sets such as land use and zoning, will allow us to determine the inventory information by outfail. The estimated time line for the systems and products discussed is two to three years. Storm Water Pond Inventorv Saint Paul's storm water ponding areas aze constructed to collect and detain flows from storm events. These ponds aze designed to reduce peak flow rates in downstream storm sewers. Figure 2 shows the storm water ponding areas in the City of Saint Paui. Tributary azea, land use type and distribution, population and design capacity for each City ponding azea will be provided in the 2002 Annual Report. _ � o�_co� , x . �• � m � , az� -.

Currently, the river is monitored to measure the effecriveness of wastewater treaunent processes, measure compliance with water quality standards, and identify pollution sources. Agencies involved in Mississippi River flow and/or quality monitoring include the Metropolitan Council, U.S. Geological Survey, MPCA, Hennepin County, and the Corps of Engineers. Monitoring data for the Mississippi River is summarized by sections or reaches and miles of the River. The first of these reaches (#401) extends from the Minnesota River to the Metropolitan Wastewater Treatment Plant. Reach #401 is partially supporting for swimming and supporting, but threatened for aquatic life. A Fish Consumption Advisory for PCB's and mercury applies to this reach. The impact of the Minnesota River is significant through this reach. The Minnesota River Basin Project involves efforts to reduce nonpoint source pollution through coordination among multiple units of government and citizens. The Mississippi River from the Ford Dam to Hastings has become a nationally recognized fishery as a result of water quality improvements and a catch-and-release policy. The river is also becoming increasingly utilized for recreation. Metro�olitan Council The Metropolitan Council does routine river water quality monitoring at two stations in Saint Paul. These are L.ock and Dam No. l, located above the Ford Dam, and Saint Paul, located at 7ackson Street and Lambert's Landing. The data is from 1994 - 1998 and contains conventionai pollutant monitoring and toxics data. Table 2 is a summary of this water quality data. Table 2: Mississippi River Mean Water Quality Values 1994-1998 Source: Met Council ot-Cob Minnesota Pollution Control Aeencv The Minnesota Pollution Control Agency monitors reach #401, Mississippi River above the Metro Wastewater Treatment Plant, sampled at the Minnesota Rowing Club dock upstream of the Wabasha Street Bridge in Saint Paul. A monitoring station at reach #402, Mississippi River above Saint Anthony Falls, sampled at the Minneapolis Waterworks intake at Fridley, provides additional upstream water quality information. Reach #201 is located above Lock and Dam #2 in Washina onlDakota County. This site provides data on water quality below the Metropolitan Waste Water Treatment Plant and as the river meets up with the St. Croix River downstream of Saint Paul. These sites are sampied monthly by the MPCA. Table 3 shows the Mississippi River Mean Water Quality Values from 1986 to 1996.

The subwatershed is 1,786 acres in size and land uses include a public golf course, zoo, pazklands, residential housing, and a few higher density shopping areas. Runoff from the golf course is routed through a series of two constructed ponds prior to entering Como Lake. Discharge from the lake enters into the Trout Brook Stortn Sewer, and ultimately discharges into the Mississippi River. Gottfried's Pit, located upstream of Como Lake, collects drainage from 549 acres including intercommunity flow from Roseville, Faicon Heights> Ramsey County right-of-ways, and St. Paul. The pond has a pumped outlet to Como Lake with a maacimum capacity of 3200 galions per minute. Como Lake average summer water quality is summarized for the period 1982-2000 in Table 4. Growing season sampling is done by the Ramsey County Lake Management Program on a yearly basis. Profile sampling in the deepest azea of Como Lake is done at least 6-8 times during the May through September. In addition to chemical measures of water quality, biological samples are collected for analysis of phytoplankton abundance and composition, crustacean zooplankton, and aquatic plant community composition. Como Lake is a biologically productive shallow lake. Even so, water quality has fluctuated over the monitoring period. Long-term plots (1982-2000) of secchi depth, total phosphorus and chlorophyll-a are shown in Figures 4, 5 and 6. This lake is considered to be hypereutrophic. b �-CO� Table 4: Como Lake Water Quality 1982 - 2000 _ Year '' ;Secclu.(n►) TP Cmg/m') CCHL(mglm'). =- 1982 0.65 219 67.7 1984 0.60 190 9$•7 1985 0.50 225 101.0 1986 1.10 310 38•� 1987 2.70 186 7.8 1988 2.00 137 24.6 1989 2.00 152 24•7 1990 0.90 198 493 1991 0.80 224 43.9 1992 1.20 152 26•8 1993 2.20 108 21•g 1994 1.70 121 29.0 1995 1.40 255 51.2 1996 1.20 276 57.6 1997 1.20 141 37.6 1998 3.20 104 9•Z 1999 3.20 ll2 11.3 2000 2.08 133 19.6 Source: Ramsey Co.

Two major projects included: 1) Biomanipulation and aeration Ramsey County received an EPA Clean Lake grant to evaluate phosphorus loads and water quality in Como Lake. Implementarion strategies included biomanipulation, which consisted of removal of rough fish by the DNR using the chemical rotenone and aigal control in 1985, followed by restocking of largemouth bass, bluegili and walleye in 1986 and implementation of fishing restriction on lazgemouth bass. Macrophyte harvesting was initiated 'an the period following the fisheries renovation and has been done during several subsequent yeazs. Also in 1985, a partial air-lift aeration system was installed to limit winter fish kilis. 2) Renovation of the Como Lake Golf Course that included the diversion of some inflows to �onds within the golf course. The renovation of the Como Lake Golf Course included the addition of several ponds to the course in 1987. Storm water runoff from three major storm sewers entering the north end of Como Lake (which contribute about 85% of the annual surface water budget for Como Lake) were partiaily diverted to two new sedimentation ponds in the golf course. A 1982 study, (Runke) concluded that there were three water quality problems in Como Lake: 1. High levels of nutrient input which leads to increased algae levels and decreased transparency; 2. Hypolimnetic oxygen depletion and subsequent sediment phosphorus release (internal loading}; and 3. An imbalance of the biology of the lake. Monitoring since the eaziy 1980's indicate water quality in Como Lake follows a cyclic pattern, as measured by water transpazency or secchi depth. The onset of the cyclic changes in water quality in Como Iake is related to the biomanipulation or fisheries management completed in 1985. This biomanipulation activity manipulates the food chain and the cycles appear to reflect nature's way of adapting to these changes. At one point in September 1986, visibility in Como Lake extended to the bottom in the deepest portion of the lake. \ A 1998 report (Noonan) on the water quality changes in Como Lake identified three factors \ which aze important to the observed water quality `cycle' and also future management strategies. � �', l. The amount of phosphorous in Como Lake drives the biological productivity, or energy level, in the system. 2. Daphnia directly affect the abundance of algae in Como Lake, which triggers the observed cyclic trend in water transpazency. 3. Macrophtyes provide valuable habitat for fish, Daphnia, and other biota and also provide a possible mechanism to reduce the abundance of algae in Como I.ake. 10 ��-CO� Lake Phalen Lake Phalen has a surface azea of 198 acres, a masimum depth of 91 feet and a mean depth of approximately 24 feet. The drainage azea is 1822 acres and land uses inciude a public golf course, parklands, residential housing, and a few commercial azeas. Lake Phalen is a meso/eutrophic lake even through annual phosphorus and water loads are chazacteristic of eutrophic lakes. It appears that the physical structure of L,ake Phalen provides a significant water quality buffer. The depth of the lake basin provides for extremely stable thermal stratification during the summer, which effectively separates the upper and lower portions of the water column. Nutrient export processes from the upper part of the water column during the summer aze very important because the nutrients lost to the bottom layer aze unavailabie to algae unUl the fall mixing period. Algae abundance remains quite low through the summer as a result, particulariy in dry summer periods. L,ake Phalen's average summer water quality is summarized for the period 1987-2000 in Table 7. Growing season sampling is done by the Ramsey County Lake Management Program on a yearly basis. Long-term plots of secchi depth, total phosphorus, and chlorophyll-a are given in Figures 7, 8 and 9.

Streets and alleys are divided into six classes, each of which receives a different level of service as defined below: Class I- Downtown or Loop streets The following service is performed on all downtown or loop streets within the following boundaries: Kelloag Boulevard on the south and west, Twelfth Street on the north and Broadway Street on the east. These streets are swept approximately three times per week and flushed five times per week during the spring, summer and fall. All rourine maintenance, including patching and repairing of street surfaces, is performed on an as-needed basis. Class II - Outlying Commercial and Arterial Streets These streets are the major arteries in the City and have both heavy volumes of vehicular and pedestrian traffia These streets also have business or commercial properties fronting on them. Typical examples aze: University Avenue, Snelling Avenue, West Seventh Street, East Seventh Street, Rice Street, Payne Avenue, Arcade Street, Summit Avenue and Grand Avenue. The Ciass II streets are swept or cleaned fifteen to eighteen times in annually. All routine maintenance, including patching and repairing of street surfaces, is done on a scheduled or as-needed basis. Class III - Residential Streets The following service is performed on all residential streeis including oiled, paved and intermediate type streets. In the spring, all residential streets receive a thorough cleaning which includes sweeping and flushing. Patching and repairing is done on a scheduled or as-needed basis. Street Maintenance initiated the foilowing policy in August 1997: Oiled streets aze seal coated on a five-year cycle until the oiled street is scheduled to be paved as part of the Residential Street Vitality Program. The street is then be added to the ten- year cycle seal coat list. All existing paved streets are on the ten-year cycle seal coat list. Approximately 12 miles of oiled streets and 60 miles of paved streets were seal coated in 2000. Oil and sand sealing of oiled streets is no longer done. Tn 1995, a recycling program was initiated for all reclaimed sand and seal coat rock. These materials are no longer hauled to the landfill. In the fall, streets are swept for leaf pickup. All material swept up during this fall cleanup is hauled to a commercial composting facility. o�-c.o� Class IV - Oiled and Paved Alleys All oiled and paved alleys are swept during the late spring. Ail routine maintenance, including patching and repairing of the alley surfaces, is performed on a scheduled or as-needed basis. Street Maintenance initiated the following policy in August 1997: Oiled alieys are seal coated on a five-yeaz cycie. Paved alleys are seal coated on a ten-yeaz cycle. Oil and sand sealing of oiled alleys is longer done. In 1995, a recycling pro�ram was initiated for ali reclaimed sand and seal coat rock. These materials aze no longer hauled to the landfill. Class V and VI - Unitnproved Streets and Alleys Unimproved streets and alleys aze right-of-ways that have not been developed. There are approximately 50 miles of unimproved streets and approximately 288 miles of unimproved assessed alleys in the City. Because they are City right-of-ways, the City has the responsibility to perform minimal repairs and maintenance work on them to make them passable and to reduce hazards. The maintenance and repair of these streets and alleys consists of patching, minor blading, and placing of crushed rock or other stabilized material. Debris Collection In 2000, the sweepings collected from city streets and alleys were tested and found to be within EPA guidelines for safe disposal in landfills and for recyciing purposes. The following approximate volumes were removed from City streets in 2000 based on vehicular measure. Class I,II � IV Totals General Debris 7,164 cu.yds. 3,336 cu.yds. 1.392 cu.yds. 11,892 cu.yds. Leaves (Fall Cleaning) 4,354 cu.yds. 12,922 cu.yds. 0 cu.yds. 17,276 cu.yds. o�-co` Street Maintenance has a Hazazdous Waste Disposal Policy in piace.

Better ice control is obtained with salt above 0°F. Sand is necessary below this temperature. Deicing is done on arterial streets first and then on residential intersections after piowing. The City has been using less sand in recent years because of the effectiveness of salt at warmer temperatures, wanner winters, and the increasing expense of sand removal from streets. The City has experimented with liquid deicing products and has not found a effective alternative to salt. The City will continue to evaluate alternative products and report the findings in the following years, annual report. Salt piles aze covered year round. Sand and salt mixture piles are stored in the open from December to February. The City does not store sand/salt mixture during the remainder of the yeaz.

Storm Drain Stenciling Education Program The City of Saint Paul has been conducting a successful storm drain stenciling education program since 1993. For the past severai yeazs the Friends of the Mississippi River (FMR) has coordinated this program. FMR is the leading cirizens' organization working to protect the Mississippi River and its watershed in the Twin Cities area. The storm-drain stenciling project is designed to meet the following three objectives: • To stencil storm drains with the message "Please Don't Pollute—Drains to River," and distribute educational door-hangers to residents and businesses in the stenciled neighborhoods. • To involve community residents in hands-on learning experiences about urban runoff pollution and ways to prevent it. • To facilitate school service leaming initiarives that include storm drain stenciling as a key component. Project Components: • Identify and organize approximately 1,200 volunteers to stencil at least 2,800 storm drains and distribute 12,000 door hangers within the City of St. Paul during each year of the project. • Provide a 30-minute educational orientation to eacA volunteer group that participates in the stenciling project. • Provide an additional one-hour lesson on urban runoff pollution with school students that participate in storm drain stenciling (approximately 40-50% of the 1,200 volunteers). • Provide a training workshop for St. Paul teachers on storm drain stenciling and water quality classroom activities that complement the service project. • Present three community workshops for city residents on urban runoff pollution and ways to prevent it. • Develop and implement an evaluation system to deternune project effectiveness. • Coordinate the purchase, maintenance and storage of all stenciling supplies and equipment. • Project staff will generate publicity for at least two stenciling groups or events each year. Metropolitan daily newspapers, TV news and community press will be targeted. 11 ot-c.oa • FMR will develop a system to evaluate the effecriveness of participating in stenciling. A pre and post test will be implemented with a variety of groups and a summary of results will be distributed to WaterShed Partners and other interested groups. • Set-up, staff and take-down the WaterShed Exhibit at the St. Paul Department of Public Works Open House in September 2001. Project Budget The total cost for the 2-year project is $54,500. The following is the detailed budget for the two-year program: 2001 Budget 2002 Budget Stencil Coordination Service LearninglEducation Evaluation Community Workshops Teacher Workshop/Support Project Management Equipment and Supplies 13,290 3,300 1,200 0 0 2,000 1,930 12,750 3,300 600 1,800 7,400 3,000 3,930 Annual Totals Project Total $21,720 $32,780 $54,500 In addition to this budget, a Met Council grant is providing funding in 2001 for the community workshops, teacher training, door hangers and some supplies. Metro WaterShed Partners Saint Paul is an active participant in Metro WaterShed Partners. This group consists of municipalities, nonprofit groups, and state, federal and local government. This partnership has leveraged grant dollars and staff time to develop educational literature and a nationally recognized interactive display. The display is now being used at schools and events throughout the Twin Cities metro area. This partnership ailows Saint Paul to tap into a pooi of expertise and to not reinvent the wheel in its own pro�am. It also provides consistency in the message that the community is hearing. St. Paul's participation in this partnership shows a good faith effort in meeting current and future requirements and has allowed the City to maximize the staff time and dollars conuibuted. In 2001, the City contributed staff time and $2,000 to the annual operating budget of the WaterShed Partners and toward purchasing a van to transport the WaterShed Exhibit. 12 O!-LO6 7.

NPDES Storm Water Permit Annual Report City of Saint Paul June 1, 2001 The City of Saint Paul submits this report in fulfillment of the annual reporting requirements of the NPDES Storm Water Dischazge Pernut MN 0061263 issued to the City of Saint Paul on December 1, 2000. This report satisfies the criteria set forth in Pernut Section 2.18. Storm Water Management Program The proposed storm water management program to be implemented in 2001 is included as Appendix A. The cost benefit analysis of individuai BMPs will be submitted in the 2002 Annual Report. Inventory Storm Sewer Outfall Inventorv Saint PauPs storm sewer outfalls are found in Appendix B. This listing includes the outfall identification number and the size of the outfall pipe. Drainage azea, land use, population, percent impervious and number of structural controls will be provided for Saint Paul's watersheds in the 2002 Annual Report. Figure 1 shows Saint Paul's watersheds. The Department of Public Works is actively developing a computer based asset and infrastructure management system. This system will include both the storm and sanitary sewer networks. A contract is currently being awarded to obtain City-wide, LIDAR generated, 1 foot digital contour mapping. When the asset and infrastructure management system is complete, we will have the data and systems necessary to accurately detemune the sub-watershed for each of the outfalls. This, in conjunction with other existing data sets such as land use and zoning, will allow us to determine the inventory information by outfail. The estimated time line for the systems and products discussed is two to three years. Storm Water Pond Inventorv Saint Paul's storm water ponding areas aze constructed to collect and detain flows from storm events. These ponds aze designed to reduce peak flow rates in downstream storm sewers. Figure 2 shows the storm water ponding areas in the City of Saint Paui. Tributary azea, land use type and distribution, population and design capacity for each City ponding azea will be provided in the 2002 Annual Report. _ � o�_co� , x . �• � m � , az� -.

Storm Water Monitoring and Modeling .Toint MonitoringProgram The Cities of Saint Paul and Minneapolis and the Minneapolis Park and Recreation Board aze participating in a joint storm water monitoring program as required by the storm water permit. Minneapolis Park Boazd staff will be conducting the monitoring program for the three year pernut term. The Storm Water Monitoring Program Manual was completed by Minneapolis Park Boazd staff and submitted sepazately to the MPCA in April of 2001. This manual is incorporated by reference. A copy of the joint monitoring agreement will be submitted to the MPCA after signatures are obtained from all three parties. The five-yeaz budget for the joint monitoring program is included in Appendix D. Sampling sites are identified in the Storm Water Monitoring Program Manual. The sampling sites were selected from the sites used in the storm water permit application monitoring program. Five sites were chosen, representative of the following land use types: two residential sites, two industriaUcommercial sites, and one mixed use site. Two sites are located in Minneapolis with three in Saint Paul. Saint Paul sampling sites are located on Figure 3. A snow melt and a rainfall event was collected in April of 2001.

Currently, the river is monitored to measure the effecriveness of wastewater treaunent processes, measure compliance with water quality standards, and identify pollution sources. Agencies involved in Mississippi River flow and/or quality monitoring include the Metropolitan Council, U.S. Geological Survey, MPCA, Hennepin County, and the Corps of Engineers. Monitoring data for the Mississippi River is summarized by sections or reaches and miles of the River. The first of these reaches (#401) extends from the Minnesota River to the Metropolitan Wastewater Treatment Plant. Reach #401 is partially supporting for swimming and supporting, but threatened for aquatic life. A Fish Consumption Advisory for PCB's and mercury applies to this reach. The impact of the Minnesota River is significant through this reach. The Minnesota River Basin Project involves efforts to reduce nonpoint source pollution through coordination among multiple units of government and citizens. The Mississippi River from the Ford Dam to Hastings has become a nationally recognized fishery as a result of water quality improvements and a catch-and-release policy. The river is also becoming increasingly utilized for recreation. Metro�olitan Council The Metropolitan Council does routine river water quality monitoring at two stations in Saint Paul. These are L.ock and Dam No. l, located above the Ford Dam, and Saint Paul, located at 7ackson Street and Lambert's Landing. The data is from 1994 - 1998 and contains conventionai pollutant monitoring and toxics data. Table 2 is a summary of this water quality data. Table 2: Mississippi River Mean Water Quality Values 1994-1998 Source: Met Council ot-Cob Minnesota Pollution Control Aeencv The Minnesota Pollution Control Agency monitors reach #401, Mississippi River above the Metro Wastewater Treatment Plant, sampled at the Minnesota Rowing Club dock upstream of the Wabasha Street Bridge in Saint Paul. A monitoring station at reach #402, Mississippi River above Saint Anthony Falls, sampled at the Minneapolis Waterworks intake at Fridley, provides additional upstream water quality information. Reach #201 is located above Lock and Dam #2 in Washina onlDakota County. This site provides data on water quality below the Metropolitan Waste Water Treatment Plant and as the river meets up with the St. Croix River downstream of Saint Paul. These sites are sampied monthly by the MPCA. Table 3 shows the Mississippi River Mean Water Quality Values from 1986 to 1996.

The subwatershed is 1,786 acres in size and land uses include a public golf course, zoo, pazklands, residential housing, and a few higher density shopping areas. Runoff from the golf course is routed through a series of two constructed ponds prior to entering Como Lake. Discharge from the lake enters into the Trout Brook Stortn Sewer, and ultimately discharges into the Mississippi River. Gottfried's Pit, located upstream of Como Lake, collects drainage from 549 acres including intercommunity flow from Roseville, Faicon Heights> Ramsey County right-of-ways, and St. Paul. The pond has a pumped outlet to Como Lake with a maacimum capacity of 3200 galions per minute. Como Lake average summer water quality is summarized for the period 1982-2000 in Table 4. Growing season sampling is done by the Ramsey County Lake Management Program on a yearly basis. Profile sampling in the deepest azea of Como Lake is done at least 6-8 times during the May through September. In addition to chemical measures of water quality, biological samples are collected for analysis of phytoplankton abundance and composition, crustacean zooplankton, and aquatic plant community composition. Como Lake is a biologically productive shallow lake. Even so, water quality has fluctuated over the monitoring period. Long-term plots (1982-2000) of secchi depth, total phosphorus and chlorophyll-a are shown in Figures 4, 5 and 6. This lake is considered to be hypereutrophic. b �-CO� Table 4: Como Lake Water Quality 1982 - 2000 _ Year '' ;Secclu.(n►) TP Cmg/m') CCHL(mglm'). =- 1982 0.65 219 67.7 1984 0.60 190 9$•7 1985 0.50 225 101.0 1986 1.10 310 38•� 1987 2.70 186 7.8 1988 2.00 137 24.6 1989 2.00 152 24•7 1990 0.90 198 493 1991 0.80 224 43.9 1992 1.20 152 26•8 1993 2.20 108 21•g 1994 1.70 121 29.0 1995 1.40 255 51.2 1996 1.20 276 57.6 1997 1.20 141 37.6 1998 3.20 104 9•Z 1999 3.20 ll2 11.3 2000 2.08 133 19.6 Source: Ramsey Co.

Two major projects included: 1) Biomanipulation and aeration Ramsey County received an EPA Clean Lake grant to evaluate phosphorus loads and water quality in Como Lake. Implementarion strategies included biomanipulation, which consisted of removal of rough fish by the DNR using the chemical rotenone and aigal control in 1985, followed by restocking of largemouth bass, bluegili and walleye in 1986 and implementation of fishing restriction on lazgemouth bass. Macrophyte harvesting was initiated 'an the period following the fisheries renovation and has been done during several subsequent yeazs. Also in 1985, a partial air-lift aeration system was installed to limit winter fish kilis. 2) Renovation of the Como Lake Golf Course that included the diversion of some inflows to �onds within the golf course. The renovation of the Como Lake Golf Course included the addition of several ponds to the course in 1987. Storm water runoff from three major storm sewers entering the north end of Como Lake (which contribute about 85% of the annual surface water budget for Como Lake) were partiaily diverted to two new sedimentation ponds in the golf course. A 1982 study, (Runke) concluded that there were three water quality problems in Como Lake: 1. High levels of nutrient input which leads to increased algae levels and decreased transparency; 2. Hypolimnetic oxygen depletion and subsequent sediment phosphorus release (internal loading}; and 3. An imbalance of the biology of the lake. Monitoring since the eaziy 1980's indicate water quality in Como Lake follows a cyclic pattern, as measured by water transpazency or secchi depth. The onset of the cyclic changes in water quality in Como Iake is related to the biomanipulation or fisheries management completed in 1985. This biomanipulation activity manipulates the food chain and the cycles appear to reflect nature's way of adapting to these changes. At one point in September 1986, visibility in Como Lake extended to the bottom in the deepest portion of the lake. \ A 1998 report (Noonan) on the water quality changes in Como Lake identified three factors \ which aze important to the observed water quality `cycle' and also future management strategies. � �', l. The amount of phosphorous in Como Lake drives the biological productivity, or energy level, in the system. 2. Daphnia directly affect the abundance of algae in Como Lake, which triggers the observed cyclic trend in water transpazency. 3. Macrophtyes provide valuable habitat for fish, Daphnia, and other biota and also provide a possible mechanism to reduce the abundance of algae in Como I.ake. 10 ��-CO� Lake Phalen Lake Phalen has a surface azea of 198 acres, a masimum depth of 91 feet and a mean depth of approximately 24 feet. The drainage azea is 1822 acres and land uses inciude a public golf course, parklands, residential housing, and a few commercial azeas. Lake Phalen is a meso/eutrophic lake even through annual phosphorus and water loads are chazacteristic of eutrophic lakes. It appears that the physical structure of L,ake Phalen provides a significant water quality buffer. The depth of the lake basin provides for extremely stable thermal stratification during the summer, which effectively separates the upper and lower portions of the water column. Nutrient export processes from the upper part of the water column during the summer aze very important because the nutrients lost to the bottom layer aze unavailabie to algae unUl the fall mixing period. Algae abundance remains quite low through the summer as a result, particulariy in dry summer periods. L,ake Phalen's average summer water quality is summarized for the period 1987-2000 in Table 7. Growing season sampling is done by the Ramsey County Lake Management Program on a yearly basis. Long-term plots of secchi depth, total phosphorus, and chlorophyll-a are given in Figures 7, 8 and 9.

Class III - Residential Streets The following service is performed on all residential streeis including oiled, paved and intermediate type streets. In the spring, all residential streets receive a thorough cleaning which includes sweeping and flushing. Patching and repairing is done on a scheduled or as-needed basis. Street Maintenance initiated the foilowing policy in August 1997: Oiled streets aze seal coated on a five-year cycle until the oiled street is scheduled to be paved as part of the Residential Street Vitality Program. The street is then be added to the ten- year cycle seal coat list. All existing paved streets are on the ten-year cycle seal coat list. Approximately 12 miles of oiled streets and 60 miles of paved streets were seal coated in 2000. Oil and sand sealing of oiled streets is no longer done. Tn 1995, a recycling program was initiated for all reclaimed sand and seal coat rock. These materials are no longer hauled to the landfill. In the fall, streets are swept for leaf pickup. All material swept up during this fall cleanup is hauled to a commercial composting facility. o�-c.o� Class IV - Oiled and Paved Alleys All oiled and paved alleys are swept during the late spring. Ail routine maintenance, including patching and repairing of the alley surfaces, is performed on a scheduled or as-needed basis. Street Maintenance initiated the following policy in August 1997: Oiled alieys are seal coated on a five-yeaz cycie. Paved alleys are seal coated on a ten-yeaz cycle. Oil and sand sealing of oiled alleys is longer done. In 1995, a recycling pro�ram was initiated for ali reclaimed sand and seal coat rock. These materials aze no longer hauled to the landfill. Class V and VI - Unitnproved Streets and Alleys Unimproved streets and alleys aze right-of-ways that have not been developed. There are approximately 50 miles of unimproved streets and approximately 288 miles of unimproved assessed alleys in the City. Because they are City right-of-ways, the City has the responsibility to perform minimal repairs and maintenance work on them to make them passable and to reduce hazards. The maintenance and repair of these streets and alleys consists of patching, minor blading, and placing of crushed rock or other stabilized material. Debris Collection In 2000, the sweepings collected from city streets and alleys were tested and found to be within EPA guidelines for safe disposal in landfills and for recyciing purposes. The following approximate volumes were removed from City streets in 2000 based on vehicular measure. Class I,II � IV Totals General Debris 7,164 cu.yds. 3,336 cu.yds. 1.392 cu.yds. 11,892 cu.yds.

Better ice control is obtained with salt above 0°F. Sand is necessary below this temperature. Deicing is done on arterial streets first and then on residential intersections after piowing. The City has been using less sand in recent years because of the effectiveness of salt at warmer temperatures, wanner winters, and the increasing expense of sand removal from streets. The City has experimented with liquid deicing products and has not found a effective alternative to salt. The City will continue to evaluate alternative products and report the findings in the following years, annual report. Salt piles aze covered year round. Sand and salt mixture piles are stored in the open from December to February. The City does not store sand/salt mixture during the remainder of the yeaz.

Storm Drain Stenciling Education Program The City of Saint Paul has been conducting a successful storm drain stenciling education program since 1993. For the past severai yeazs the Friends of the Mississippi River (FMR) has coordinated this program. FMR is the leading cirizens' organization working to protect the Mississippi River and its watershed in the Twin Cities area. The storm-drain stenciling project is designed to meet the following three objectives: • To stencil storm drains with the message "Please Don't Pollute—Drains to River," and distribute educational door-hangers to residents and businesses in the stenciled neighborhoods. • To involve community residents in hands-on learning experiences about urban runoff pollution and ways to prevent it. • To facilitate school service leaming initiarives that include storm drain stenciling as a key component. Project Components: • Identify and organize approximately 1,200 volunteers to stencil at least 2,800 storm drains and distribute 12,000 door hangers within the City of St. Paul during each year of the project. • Provide a 30-minute educational orientation to eacA volunteer group that participates in the stenciling project. • Provide an additional one-hour lesson on urban runoff pollution with school students that participate in storm drain stenciling (approximately 40-50% of the 1,200 volunteers). • Provide a training workshop for St. Paul teachers on storm drain stenciling and water quality classroom activities that complement the service project. • Present three community workshops for city residents on urban runoff pollution and ways to prevent it. • Develop and implement an evaluation system to deternune project effectiveness. • Coordinate the purchase, maintenance and storage of all stenciling supplies and equipment. • Project staff will generate publicity for at least two stenciling groups or events each year. Metropolitan daily newspapers, TV news and community press will be targeted. 11 ot-c.oa • FMR will develop a system to evaluate the effecriveness of participating in stenciling. A pre and post test will be implemented with a variety of groups and a summary of results will be distributed to WaterShed Partners and other interested groups. • Set-up, staff and take-down the WaterShed Exhibit at the St. Paul Department of Public Works Open House in September 2001.
