Minneapolis Pazk Board staff conducted the monitoring program. The Storm Water Monitoring Prograw Manual and the Joint Monitoring Agreement were submitted to the MPCA in 2001 and are incorporated by reference. All of the Joint Monitoring Program data, results, summary and budget aze found in the Appendix. The 2004 Climatological Summary is also located in the Appendix. The sampling sites were selected from the sites used in the storm water pemut applicarion 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 and three aze located in Saint Paul. The City is in the process of developing partnerships with the Capitol Region Watershed Dishict and the Ramsey-Washington Metro Watershed District to conduct the permit monitoring program in 2005. Pollutant Loading Calculations Annual and seasonal pollutant loading calculations are included in the Appendix.

Tlus system is being jointly implemented with St. Paul Regional Water Services to gain substantial economies of scale. The CMMS implementation is continuing as previously reported. The softwaze has been installed and configuration is neazly complete. Public Works has an ongoing contract in place with a data conversion vendor. System start-up is scheduled for August 21, 2005. GIS data from the conversion process will be loaded to coincide with system start-up. NPDES Permitted Facilities Facilities in Saint Paul that aze issued NPDES permits by the MPCA aze found in the Appendix. Indush Land Use Indushial land uses may generate higher concentrations of hydrocazbons, trace metals, or toacicants than aze found in typical storm water nxnoff. A map showing the azeas of indushial land use in St. Paul is included in the Appendix. Storm Water Ponds Saint Paul's storm water ponding azeas are constructed to collect and detain flows fi storm events. These ponds aze designed to reduce peak flow rates in downstream storm sewers. A map showing the storm water ponding areas in the City of Saint Paul is found in the Appendis. The Appendiz also contains the hibutary azea, population and design capaciTy for each City ponding area. A list of storm water ponding azeas by Watershed is included in the Appendix.

Minor maintenance was completed as needed from the inspection reports. In addition to these inspections, pond inlets and ouflets aze checked routinely after rainfalls for blockage. A summary of the pond inspection and maintenance activities is included in the Appendix. The City's 22 storm water ponding areas will be inspected in the spring of 2005. Maintenance will be conducted as necessary. Arlington Pascal Storm Water Improvement Pro�ject The Cities of St. Paui, RoseviIle and FaIcon Heights along witfi Ramsey County and the Capitot Region Watershed Dishict (CRWD) formed a parCnership in 2003 to conduct an evaluarion of the Como 7 sub-watershed. The results of the evaluation provided a plan to reduce the frequency and duration of flooding in the watershed and at Midway Pazkway, while improving water quality in Como Iake. Tlus was accomplished through an improved drainage system, ponding azeas, rainwater gazdens and infiltration h The watershed district worked with the Cily of St. Paul Public Works Depattment to plan and design several rainwater gazdens on McKinley Street and infiltration trenches along Arlington and Nebraska Avenues as part of the Arlington/Pascal Resideniial Street Vitality Program. In addition to these improvements, the CRWD is working with the Division of Parks and Recrearion to construct water qualiTy improvements in Como Park. Cons�uction is to begin in the spring of 2005. A flyer suwniarizing the project is found in the Appendis. Bruce Vento Nature Sanctuarv Saint Paul's newest pazk, the Brnce Vento Nature Sanctuary, is a unique.27-acre urban natural azea neaz the Mississippi River at the foot of Dayton's Bluff. A former rail yazd, the land has been transformed through years of hard work by Saint Paul's East Side and I.owertown comnnunities and more than 25 public and private partners. A community celebration introducing the pazk was held in May of 2005. Lake Phalen Shoreland Restoration Project This restoration iniriative is an important element in both St. Paul Parks and Recreation and the Ramsey-Washington Metro WD's overall objectives. Land managers understand that vegetation is essential to preventing soil erosion. In order to create a shoreline that will withstand erosive forces over the long-term and impmve the Phalen Lake ecosystem, native shoreline plants need to be rein�oduced and a natural shoreline created. A nat�ual shoreline is made up of a network of strong vegetarion to hold soil in place. Using native plants accustomed to the Phalen shoreline environment and protecting the plants in the short term, as their mots aze establishing, is imperative to the long term viability of the shoreline. The Phalen Shoreline Restoration Project incorporates all of these considerations and creates a natural and long lasting shoreline. Eroded azeas along the west, south and south east shores were graded and stabilized. Native seedlings and seeds were planted into erosion control mats. A majority of the sites axe complete with work on some sections going into 2005 and 2006. Page 8 Storm Sewer Consiruction and Maintenance Catch Basin Inventorv As part of the on-going effort to implement CMMS, a consultant was hired to conduct a field survey of the City's catch basins. Workers using GPS equipment located all city owned catch basins. The total number of catch basins inventoried was 25,922. Luella/Orange Catch Basin Studv Area The Catch Basin Pilot proj ect as required by the permit was completed in 2003. City staff decided to continue studying this azea. The catch basin accumulation was measured in the fall of 2004. The basins were cleaned and then dimensions of each catch basin sump were determined. The selected study area is the tributary azea to the Luella/Orange sampling site. This 95 acre site is 100% residential. Page 9 � �� .`�$ � � Street Management Program Responsible department: Public Works Street Maintenance. Tazgeted Pollutants: Sediments, nutrients, oxygen-demanding substances, chlorides Perfo2mance Measures: Frequency of sweeping on each street type, quantity and breakdown of materials removed. Quantity of deicing and anti-icing materials used. Pemut Section: 2.8 Roadways Street Cleanin� and Maintenance Prog� The City of Saint Paul cottducts a street and alley cleaning prograin to promote the health and welfaze of its citizens and to reduce the amount of pollutants to receiving waters from storm water dischazges. Streets and alleys are divided into seven classes, each of which receives a different level of service as defined below: Class I-A - Downtown or Loop streets Downtown or loop sireets are within the following boundaries: Kellogg Blvd. on the south and west, 12�' St. on the north and Broadway St. on the east. These streets aze swept appm�mately three times per week during the spring, suwmer, fall and winter as weather allows. All routine maintenance, including patching and repairing of street surfaces, is performed on an as-needed basis. Class I-B - Downtown Streets (Brick) The following are the downtown brick streets: St. Peter and Wabasha Streets, from Kellogg Blvd. to 6 St., and 4` 5�', and 6th S�eets, from St. Peter to Wabasha. These streets are swept approximately three times per week during the spring, summer, fall and winter as weather allows. All routine 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 pedeshian traffic. These streets also have business or commercial properties fronting on them. Typical examples aze: University Ave., Snelling Ave., West 7`� St., East 7`� St., Rice St., Payne Ave, Arcade St., Summit Ave. and C'Trand Ave.. Class II streets aze swept or cleaned fifteen to eighteen times annually on the following schedule: every two weeks in April, May, October, and November for spring and fall cleanup and every three weeks in June through September for litter, tree debris and sediment. All routine maintenance, including patching and repairing of sireet surfaces, is done on a scheduled or as-needed basis. Page 10 t� �— _; � .�' .� _ � � a Class III - Residential Streets In the spring, all residenrial streets, including oiled, paved and intermediate streets, receive a thorough sweeping. Patching and repairing is done on a scheduled or as-needed basis. Oiled streets aze chip sealed on a 5-year cycle. All existing paved streets are on the 8-year cycle chip seal list. Approximately 12 miles of oiled streets and 60 miles of paved streets were clup sealed in 2004. Oil and sand sealing of oded streets is no longer done. The City recycles reclaimed sand and seal rock. These materials are no longer hauled to the landfill. In the fall, streets aze swept for leaf pickup. All material swept up during ttus fall cleanup is hauled to a commercial composting facility. Class IV - Oiled and Paved Alleys All oiled and paved alleys aze swept during the late spring. All routine maintenance, including patching and repairing of the alley surfaces, is performed on a scheduled or as-needed basis. Oiled alleys are chip sealed on a 5-year cycle. All existing paved alleys aze on the 8-yeaz cycle chip seal list. Oil and sand sealing of oiled streets is no longer done. The City recycles reclaimed sand and seal rock. These materials aze no longer hauled to the landfill. Class V and VI - Unimproved Streets and Alleys Unimproved streets and alleys aze right-of-ways that have not been developed. There are approacimately 50 miles of nnimproved streets and approacimately 288 unimproved assessed alleys in the City. Because they are City right-of-ways, the City has the responsibility to perform minuual 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 Sweeping is a major operation for the Street Maintenance Division and is done every month of the yeaz, day and night. Elgin Pelican mechanical sweepers handle the vast maj ority of the sweeping. An Elgin Crosswind Regenerative air sweeper is utIlized Downtown. A second Crosswind will be purchased and in use in 2005. In recent years, the target date for complerion of spring sweeping has moved up from Memorial Day to May 15th. The primary material swept in the spring is sand from ice control operations. Fall cleanup is done during the last week of October and the first half of November. The fall sweep is timed so that a majority of the leaves are down and enough time is allowed to sweep all St. Paul streets before the November snows. Currently the wide variety of trees with varying leaf drop times makes it impossible to wait for all of the leaves to drop. To compensate for this, touch up sweeping continues most yeazs through November and eazly December. In the interest of conrinued improvement to our sweeping prograw, workers attend training and best management pracrices aze implemented. In 2001, the sweepings collected from city streets and alleys were tested and found to be within EPA (Environmental Protection Agency) guidelines for recycling purposes after screening out waste and debris. Only 7 to 10% of swept up material is disposed of in a landfill. The following table shows the volumes removed from City streets in 2004.

Any of these materials collected from city streets aze disposed of in envuonmentally acceptable means. Street Maintenance also services over 320 hash receptacles and disposes of refuse from neighborhood cleanups each yeaz. Ice Control Operations Minuesota weather requires ice control from late September through euly May. Frost forming on bridge decks is usually the first and last ice control event of the winter season. From eazly November through mid-April, the need for pavement treahnent is determined by temperature and precipitation Frequency of snow events through the winter season ittfluences amounts of material used. The City's foremost objective is Yo maintain safe roads for all users. The consequences of icy roads aze longer travel times, adverse economic impact, accidents and injuries. Sa1t is the primary material used to melt snow and ice. Salt is theoretically effective to -6°F but factors such as dazlmess, continuing snow, temperatures below 10°F or type and quantity of precipitation all reduce melting performance. Sand is sometimes used in conjunction with salt to enUance traction; usually when temperatures aze below 10°F and snowfall amount is likely to be greater than 3 inches. Specific applicalion rates aze decided upon for each snow event and adjusted to the ..�;n;m� �o�t necessary to achieve the desired results. St. Paul has made use of alternative ice control products for the past ten years. The best results have been with liquid magnesium chloride blends applied to selected bridge decks as anti-icing material to prevent bridge frost. One application of 20 gallons per lane mile eliminates frost formation twice before needing re-application. Our evolving plan currenfly is to spray 16 bridges in the City, when conditions aze favorable for good performance. Tlus pmgram is reducing salt and sand/salt use. Another product of significant interest is salt treated with liquid magnesium chloride and aariculhual byproducts. Potential benefits aze better melting perfonvauce, residual value, and reduction in amount of salt used. Page 12 - . � , Salt is covered year round to eliminate runoff. Sand and salt misture piles aze stored in the open from December through February. The City does not store sand/salt mixture during the remainder of the year and likely will avoid outside storage of all products year round beginniug in 2005-2006. Storage facilities are located at the following locations: 873 N. Dale Slreet (Increased storage is expected at this location in 2005.) 510 East Sth Street 310 South Victoria Street Ice control materials used as of March 15, 2005 for the 2004-2005 Winter Season 16,250 tons salt 4,483 tons sand 3,000 gallons Magnesium Chloride 1,200 tons treated salt Emplovee Trainin� St. Paul Public Works is an advocate of networking within the industry for informarion and regulazly attends events such as the American Public Works Association North American Snow Conference. Street Maintenance staff attended MnDOT's Circuit Training and Assistance Program in November of 2003. A total of 70 employees attended the traiuiug session on Sensible Material Applicarion for Snow and Ice Conh�ol. The main purpose of this session is to train employees to get the most out of every application, maintaining the safest roads possible in the most economical way, while pmtecting the environment. The session addressed the following: abrasives, salt, pre-wetting. anfi-icing, equipment calibrarion and material storage. In November of 2004, ten newly hired workers attended a 90 minute ice control class and did an all day ride along with an experienced driver.

The ordinance bans the use of fertilizer containing phosphoms in the CiTy with the exception of establishing a new lawn or if a soIl test shows that phosphorus is needed. The ordinance also requires retailers to cleazly label fertilizer containing phosphorus and post a notice advising that the use of such fertilizer is restricted within the City. In addition, the City amended an ordinance regulating commercial applicators in Saint Paul. The amendment requires commercial fertilizer applicators to be licensed by the City in addition to the pesticide applicators. The state passed legislation that sets a 0% phosphorus ban on fertilizer for the metro area effecrive in 2005. A fact sheet about this legislarion is included in the Appendix. The City will continue to coordinate with existing education efforts, such as WaterShed Partners, to develop and distribute educational pieces. The Public Education and Outreach section contains additional infoimation on education efforts. Pesticide and Fertilizer Use on City Facilities The City has strict requirements that aze followed for applications on all City facilities. The Department of Public Works does not apply pesticides or fertilizers. All City prograius for pesticide use shall be reviewed and approved by the city council prior to any application upon ci?y properry. Each use of pesticide or fertilizer is documented and reported to the City Clerk and to the District Council in which the application occurred. City policy was developed upon the recommendarions of a report done by the City Council Investigation & Research Center in May of 1990. In addition, all City staff that apply pesricides and fertilizers must be licensed in accordance the City Ordinance, which requires commercial applicators to be licensed by the City. The City will continue to apply pesricides and fertilizer and document and report use in accordance with these requirements.

The permit requirement was to conduct the prograui throughout the entire City in a 5 year period. The field screening inspection program was conducted in conjuncrion with the outfall and pond inspecrion progiam. The results of the field screening conducted in 2004 can be found in the Appendix. Inspections are done during dry weather in order to detennine if there is any non- storm water discharges in the storm sewer system. A LaMotte Storm Drain Pollution Detecrion kit is used to test the samples. The ldt includes tests for pH, phenols, chlorine, copper and detergents. In 2004, 17 sites were inspected for flow representing 9,754 acres or 29% of the City's drainage area. Flow was found at 11 sites out of the 51 sites inspected. Flow at all 11 sites was determined to be ciean flow. The results of this program to date show the same conclusion reached in the dry weather field screening required for the permit application. Dry weather flows are not a significant source of pollution in Saint Paul. A majority of the sites that have flow are cleaz water, such as ground water and lawn sprinkling water. This screening was completed in 2004. In 2005, the City will continue to check for dry weather flow during the annual inspections of outfalls and ponds.

We can track the number of door hangers dishibuted, the number of storm drains stenciled and the number of volunteers involved. For each storm drain that is stenciled, the message is going out to the volunteers doing the project and the residents in that area. As the program develops, the emphasis is moving away from maxim;z�g �e number of storm drains stenciled to education of the volunteers participating in the program.

Metro WaterShed Partriers is an innovative, dynauiic coalition of over 40 public, private and non-profit organizations in the Minneapolis/St. Paul metropolitan azea that, through collaborarive educarional outreach, teaches residents how to caze for area waters. Ongoing projects include Project NEMO (Nonpoint Source Pollution Education for Municipal Officials), Volunteer Stream Monitoring Partnership, the WaterShed Eachibit and the Communications Campaign. This partnership has leveraged grant dollars and staff time to develop educational literature and a narionally recon i�ed interactive display. The WaterShed e�ibit was at schools and events in and around Saint Paul in 2004. The WaterShed is also at the Minnesota State Fair in the Department of Nariuxl Resources Building each yeaz. The Partners staff it during this time. Appro�mately 100,000 people visit the WaterShed at the State Fair each yeaz. Friends of the Mississippi River setup the WaterShed at the St. Paul Public Works Open House held in August of 2004. Metro Clean Water Camnai�n To assist Twin Cities Phase II Storm Water Prograui cities with educarional efforts Metro WaterShed Partners is conducting the Metro Clean Water Campaign. This type of collaboration allows for the development of a consistent message, which is dishibuted cost effectively. The project was funded by Metropolitan Council Environmental Services, the Minuesota Office of Environmental Assistance and the Minnesota Pollution Control Agency. Periscope was hired as the advertising agency to work on this campaign along with a committee made up of state agencies and local units of government. A City of Saint Pau1 staff person is a member of this committee. The campaign will be continued in 2005 with money raised from local units of government. The objective of the campaign is to support city-based education efforts by: • Creating & distributing clean water and yard waste management images and publications via a website to cities and watershed distdcts. • Electronically dishibuting key education materials to cities on a timely basis. • Including messages in TV weather broadcasts and a TV weather website in cooperation with Stormcenter and KAREl l. • Launching the cleanwatermu.org website which contains information and products from the campaign. It will be updated and expanded as the campaign progresses. • Spring 2004 and 2005 radio ad campaigns focusing on using phosphorus free fertilizer. • Print ads were developed and placed in community newspapers and the two daily papers in 2004 and in the daily papers in the spring of 2005. The Me�o Clean Water Campaign won a MnGREAT Award in 2004. MnGREAT recognizes environmental achievements by government employees. The award recoa i�ed the consistent clean-water messages in mass media across the Twin Cities metro area and the ready-to-adapt storm water educational materials made available to cities and neighborhood organizations.

This was the Sth yeaz of tlus event and the 3rd yeaz that it was held in Saint Paul. The Watershed Dishict estimates that 1000 people atteud this free family fesrival. The Pazks Department is assisting in coordinating tlus event, which is being held in a City Pazk. The Public Works Department provides volunteers and a street sweeper to be on display for this event. A flyer for the 2005 event is included in the Appendix. Como Lake Water Festival The Capitol Region Watershed District, Black Beaz Crossings and the St. Paul Pazks and Recreation Department sponsor this annual family event at Lake Como to celebrate clean water. Tlus event includes elchibits on lawn caze, hands-on educational activities, tips for impmving lake water quality, fishing demonstrations, a Como L,ake clean-up, tour of rain gazdens and shoreland restoration sites, and animals from the Como Zoo. The Public Works Department pmvides a street sweeper to be on display far this event. A flyer for the 2004 event is included in the AppendiY. Grand Excursion 2004 Grand Excursion 2004 was a collaborative effort of more that 50 upper Mississippi River communities and dozens of regional organizarions guided by Graud Excursion, Inc., a non-profit organization coordinating this four-state initiative designed to celebrate the upper Mississippi River region_ The largest riverboat and steamboat flotiila in over a cenhuy followed the 1854 Grand Excursion's mute up the Mississippi River, fi the Quad Cities of Iowa and Illinois to the Twin Cities of Minneapolis and Saint Paul. River Ea�loration Trunks The River Exploration Truuks aze valuable collections of resources that will bring together science, history, culture, literature, art, music, technology and environmental education resources to foster students' personal understanding of the River and educate the next generation of river stewazds. This educational program joins together fow states (IA, IL, MN, WI), 54 communities, 788 schools, 50,000 students, thousands of teachers and countless volunteers. Annual Spring Parks Clean-Up St. Pau1 Pazks and Recreation's hosts an Annual Spring Pazks Clean-Up every year during the month of April. The City provides clean-up supplies, trash removal, recycling services and a "tLank you" celebration. During this event families, groups and individuaIs cIean irash from Saint Paul's pazks and recreation centers. Over the last 20 years, over 54,000 volunteers have removed over 390,000 pounds of trash and recyclables during the Spring Parks Cleanup. Without the help of volunteers during the cleanup, trash accumulates in these natural areas harming wildlife, polluting lakes and rivers and detracting from the beauty of our community. This event is a fun and effective way to impmve the environment in our local community. The event is sponsored by Saint Paul Pazks and Recreation, Ramsey-Washington Metro WD, Capitol Region WD, Xcel Energy, Captain Ken's Foods, Super America, Volunteer Resource Center, BFI, Waste Management, Vasko Disposal Solutions, Coca-Cola, Genpak and Citrus Systems, Inc.

Permit Sections 2.16 Coordination with Other Governmental Entities As stated in each section of this report, the City of Saint Paul coordinates with many entities in all aspects of managing storm water. Each project, event or activity listed involves numerous entities. By its nature, water does not follow political boundaries therefore it is necessary to cooperate with other enrities in order to effecrively resolve these issues. The limited resources that aze available must be used efficienfly with min;m� duplication of efforts. The main azea of coordination on these issues is with St. Paul's watershed mauagement organizarions. In 2005, the City will be working with the watershed organizations on the development of the City's Local Surface Water Management Plan. Saint Paul Local Surface Water Management Plan The City of Saint Paul issued a request for pmposats in April of 2004 to hire a consulting engineering firm to complete its Local Surface Water Management Plan. A consultant was selected in May of 2004. This plan will be developed to meet the requirements of Minnesota Statue 103B235 and Minnesota rules 8410.00160 and 8410.0170. The plan must aLso be in conformance with the Watershed Management Plan's of St. Paul's watershed management organizations. The Metropolitan Council also reviews the local water plans in the Meiro Area. The plan will be completed in the summer of 2005. Watershed Organizations The following briefly describes each organization and provides some of the cooperative efforts between the City and its watershed management organization. Many examples of coordination can be found throughout this report. The City provides a staff person to coordinate efforts with each of its watershed organizztions. A map of St. Paul's watershed ma.na.gement organizations is found in the Appendiz. Mississippi Watershed ManaEement Organizafion (MWMO) The MWMO is a joint powers organization which lies mainly in Minneapolis. Members include the Minneapolis Pazk and Recreation Board, Minneapolis, St. Anthony Park, Lauderdale and St. Paul. A small area in the northwest comer of St. Paul is within the MWMO boundary.

The purpose of these samples was to ensure sample integrity. Field bianks consisting of deionized water accompanied samples from the sites to the analytical laboretory. One fieid blank was used for the five sites each sampling trip for a complete analysis of NPDES parameters. An equipment blank (1-2 L sample) was collected on 12/7/04. To collect the equipment blank, a large bottle of deionized water was placed at the end of the samplers pump tubing. The intake line was flushed and pumped by pulling deionized water through the sampler, simulating the pre-sample flush. The flush water was back-pumped to waste and then a sample of deionized water was collected. The sampie was of su�cient volume to allow analysis of all parameters. Data Handling, Validation and Reporting Manual transcription of data was minimized to reduce the need for data validation. However, 10% of all manually transcribed data were checked for transcription errors. Since none of the checked data were found to be incorrect, all transcribed data were not checked. See Section 27, Quality Assurance/Quality Control Assessment Report for details. Field measurements were recorded on the Field Measurement Form in the Field Log Book. All field measurements were entered into a computerized database. Nard copy and computerized data from the laboretory were fonvarded to the Monitoring Manager, as defined in the Storm 2�G4 L�'at€r Res�c�rces r2e�4rt — ta�i�rea�otis Park &?�ecreatiora 3aard Page 10 Appendix � :z m �� ^ � � � � Water Monitoring Progrem Manual (MPRB, 2001), for review. Computerized data from the laboratory were checked and passed laborato,ry quality assurance procedures. � The Field Coordinator reviewed data approaching the extremes of the range for consistency. Ultimate responsibility for flagging data was jointly shared among the Monitori ng Manager, the Feld Coordinator and the Laboratory Quality Assurence Coordinator, as defined in the Storm Water Monitoring Program Manual (MPRB, 2001). The Laboratory Quality Assurance Coordinator was responsible for verifying i nconsistent data within the laboratory. Data considered inconsistent were those data values eacceeding three times the standard deviation. The Field Coordinator reviewed computerized data received from the analytical laboratory for completeness. For data reported below the reporting limit, the reporting limit value was divided in half and then used 4or all calcu{ations. A Chain of Custody form accompanied each set of sample bottles delivered to the lab. Each sampler tray was labeled ind icating the date and time of collection, site location and the field personnel's initials. The time each sample was collected was recorded from the ISCO sampler onto field sheets. A complete description of inethods can be found in the Storm Water Monitoring Program Manual (MPRB, 2001). Results of this season's monitoring can be found in the following results section. Statistics for event mean concentrations were calculated using Microsoft Excel spreadsheets. The computer program FLUX and computer model P8 were used to calculate flow-weighted mean concentrations and estimate snowmelt runoff vofume respectively. A description of FLUX as described in the FLUX manuai (Walker 1996): "FLUX is an interactive program designed for use in estimating the loadings of nutrients or other water quality components passing a tributary sampling station over a given period of tim e. These estimates can be used in formulating reservoir nutrient balances over annual or seasonal averaging periods appropriate for application of empirical eutrophication models. Using six calculation techniques, FLUX maps the flow/concentration relationship developed from the sample record onto the entire flow record to calculate total mass discharge and associated error statistics. In many cases, stratifying the data increases the accuracy and precision ofloading estimates." A description of P8 as described in the software's introduction: "PS is a model for predicting the generation and transport of stormwater runoff pollutants in small urban catchments... Simulations are driven by houriy rainfall and daily air-temperature time series..." 2t34� l�later f�escscarc�s R�pc�rt - Mirsneapa[is Fark & P.ecre�tian �aard Page 11 Appendix � �� o ��, RESULTS & DISCUSSION Event mean concentrations are listed in Table 23 F. The 7/11/04 event was coliected after 24 hours 6ut was still used in calculations because the numbers were comparable to other events. EYpired parameters were dropped for this event (cBOD, TDP, F. Coli). Tabie 23G lists the mean, median, maximum, minimum, and standard deviations for all measured parameters. Many parameters fluctuate with season. Typically, maximums for most parameters were reached during early spring and fa II, This was probably due to snowmelt accumulations and leaf litter, respectively. Peak phosphorus levels during snowmeit were probably due to an accumulation of animal, lawn, and leaf litter waste in late fall and during winter months. The maximum 7P of 2.03 mg/L at Site 2 was on li/19/04. This sample was very dark brown and mostly organic matter. In general, TKN had high peaks during snowmelt and spring. Both NO3NO2 and NH3 showed increases during snowmelt and fall. Leaf litter and debris accumulation over winter, fertilizer application in the spring, and decomposing leaf litter in the fall are possible reasons for high values during these periods. High CI conc�ntrations are typical for stormwater runoff during winter and early spring months when street salt is used. Chloride levels exceeded U.S. Environmental Protection Agency's Chronic Freshwater Quality Criteria of 230 mg/L oniy during these months. All samples after May were well below the standard. Currently there is no chloride standard for stormwater. Also, specific conductivity, TDS, and TSS generally tend to be high during winter and spring months. High TSS values might be attributed to accumulated sand applied to icy roads. AlmosY all maximum metal values followed the same trend as TSS. Fecal coliform values were lowest for the snowmelt event and generally peaked during sum mer months. Sampled data were fairly comparable to typical urban stormwater data (Tables 23H and 23I). Table Z3H shows the TP and TKN medians for MPRB monitored residential and commercial sampled sites were slightly higher than reported Nationwide Urban Runoff Program (NURP) values. All metals, NO3NO2, and TSS were lower than reported NURP values. All BOD median values were higher than NURP values. The MPRB mean concentrations for TP, TDP, TKN, NO3NO3, TSS, and all metals were less than NURP, Minneapolis Public Works, and City of St. Paui reported average concentrations in Tabie 23I. The MPRB mean concent2tions of BOD and TDS were comparable to other reported values shown in Table 23I, while NH3 was slightly larger. 2QC34 l+Vater s2esasarc�s 2ep4rt -�6i€��eapn[ss Pari� c� EZecreat6on �aar�+ Page 12 Appendix x � c :J Q Q � � 0 � N L � � d �M+ .

The model P8 was used to estimate daily flows for snowmelt events from January through April. Daily flows were used as input for the interactive program FLUX. Daily temperature and houriy precipitation files obtained from the National Oceanic and Atmospheric Administration (NOAA) National Data Center (NNDC) were used as input for P8. The rain gauge location is the Minneapolis/St. Paul International Airport. All flow-weighted mean concentrations were calculated using FLUX (Table 23J). FLUX calculates total mass discharge and associated error statistics based on six different calculation methods. Calculation methods 1-Direct Mean Loading and 5-Regression, Second-Order were ignored because they are inappropriate for storm sewer applications where the daily flow file contains a significant num ber of zero flows (Bruce Wiison, personal communication, 2001). In general, calculation methods 2- Flow-Weighted Concentration and 6- Regression Applied to Individual Daily Flows were used. Sample mncentrations and associated daily average flows were used as input for these calculations. The data were often stratified by flow or seasons to achieve the most accurate and precise results (Table 23K). The highest TP, TDP, and TKN concentrations were estimated at Site 1 and Site 2. Both sites are primarily residential land use. Site 4 had the highest metals concentrations. This could be due to runoff from University Avenue which is highly commercialized, densely populated and a major commuter route. Site 4 has approximately 40% commercial land use and 60% residenfial land use. The lowest concentrations of phosphorus, TKN, NH3, CI, cBOD, and TDS were found at Site 3. Site 3 has 100% industrial land use coverage. Low phosphorus could be attributed to limited fertilizer application, minimal soil disLurbances, and low inputs from lack of trees (leaves and seeds). Flow-weighted mean concenttations for CI and TDS were difFicult to estimate using FLUX due to large outliers from the single snowmelt sample therefore these estimates should be used with discretion. Flow-weighted mean concentrations for Cd should be used with discretion as only one sample was above the minimum detection limit (MDL). When samples are below the M DL then half the MDL is used for calculations. Table 23L includes flow-weighted mean pollutant concentrations reported by the U.S. Geological Survey for various sites within the Twin Cities (as cited in MPCA, 2000). The Yates watershed was a stabilized residential area. Iverson was a residential watershed under development while Sandberg was predominantly light industrial land use as reported by the U.S. Geological Survey (as cited in MPCA, 2000). Sites 1 and 2 are most comparable to the Yates watershed land use characteristics. Site 3 is more closely related to the Sandberg watershed land use characteristics. When comparing the flow-weighted meam m�centrations for these sites, it is evident that Site 1 an d 2 have lower concentrations tha n Yates for all parameters. Site 3 also has lower flow-weighted mean concentrations than Sandberg. The water quality of Sites 1-3 is better than the study sites of 1980. Event mean concentration seasonal staYistics for a mmbination of all sites were calculated and are listed in Table 23M.

The entire summary can be found at httn:/lciimate.umn.edu/cawaplmorl041231.bct. Highlights of this summary are presented here: "A warmer than normal year, witfi excess precipitation in many places... Cold temperatures in late January and February drove frost deep into the ground, beyond 60 inches in places. Many septic systems were frozen and homeowners had to bear the expense of thawing them out. A snow burst on the morning of March 8th produced 2-3 inches of snow in an hour, snarled traffic and caused numerous accidents in the Metro area. Over 25 Minnesota communities reported temperatures of 90 F or higher on Apri I 28�'.... A terrific wind storm in the Twin Cities on Mother's Day (May 9th) brought down many trees, especially in Como Park. A very cold growing season in Minnesota caused crops to develop very slowly... the crop season was rescued by one of the warmest Septembers in history and most crops reached maturity. For many communities there were more days with 90 F or greater temperatures in September than any other month of the year, a highly unusual pattern... Fnally, a freezing rain and driule on Decemher 20th across central Minnesota produced nearly 350 traffic accidents, the most for any single day of the yea r." TWIN CITIES RAIN GAGE COMPARISON Precipitation amounts can vary greatly within a city. In order to undersland the pattern of a storm event, rainfall data from other agencies was obtained from various sites throughout Minneapolis and St. Paul. The rain gages are not heated and cannot measure snowmelt, therefore oniy totals for the growi ng season (April - October) were calculated. Table 25B lists the rain gages by operator and their locations. The Minneapolis Park & Recreation Board (MPRB) obtained data from four Ramsey Soil and Water Conservation District (RSWCD) manual rain gages. The rain gages were located near the Nationwide Pollutant Discharge Elimination System (NPDES) sites in St. Paul. Volunteers for the RSWCD recorded the data from the rain gages, and monthly totals were calculated. The monthly totals were then averaged for ali four sites (Table 25C, Figure 25B). The MPRB operates a tipping bucket rain gage in southwest Minneapolis and the City operates a tipping bucket rain gage downtown. The data is recorded from employees at the rain gage location. Monthly totals were calculated (Table 25C, Fgure 256). 2�3�4 �N«ter R�_=ourc2s ;Ze�€art — C�t'sn�ae�pa!is Par�c �u �ecraaticn �aar� Page26 Appendix � � `' � � � .6 -� .� � .� .s. Table 25B.

All flow weighted mean concentrations were calculated using the model FLLTX . FLUX calculates total mass dischazge and associated error staristics based on six different calculation methods. Calcularion methods 1-Direct Mean Loading and 5-Regression, Second-Order (Walker 1987) were ignored because they aze inappropriate for storm sewer applicarions where the daily flow file contains a significant number of zero flows (Bruce Wilson, personal communication, 2001). Sample concentrarions and associated daily average flows were used as input for these calcularions. In order to achieve the most accurate and precise results, the data was often stratified by flow or by season. The model P8 was used to calculate daily flows for the snowmelt events during January through April. Daily temperature and hourly precipitation files obtained from the National Oceanic and Ahnospheric Administration (NOAA) National Data Center (NNDC) were used as input for P8. A description of FLiTX as described in the FLiJX manual (Walker 1996): "FLIJX is an interactive program designed for use in estimating the loadings of nuh or other water quality components passing a tributary sampling station over a given period of 6me. These estimates can be used in formulating reservoir nutrient balances over annual or seasonal averaging periods appropriate for application of empirical eutrophication models. Using six calculation techniques, FLUX maps the flow/concentrarion relationship developed from the sample record onto the entire flow record to calculate total mass discharge and associated enor starisrics. In many cases, stratifying the data increases the accuracy and precision of loading estimates." A description of P8 as described in the software's introduction: "P8 is a model for predicting the generation and transport of stormwater runoff pollutants in striall urban catchments... Simulations are driven by hourly rainfall and daily air-temperature time series..." Page 29 Appendix 2004 Pollutant Loading Calculations r , , -- � _ s�a � � ° _ _ Pollutaut loadings in pounds were calculated for each watershed using the following formula: L = IP �J) �v) / 12l �C) �A)� P= rainfall depth in inches over the desired time period Pj = correction factor for storms that produce no runoff Rv = runoff coefficient, which is the fraction of rainfall which is converted to runoff C= event mean concentrarion of the pollutant (mg/1) A= area of the development site in acres Values used in loading calculations: P= 2739 inches annual rainfall Pj = 0.85 Rv and A- See Watershed Inventory in Appendix C= flow weighted mean concentration The flow weighted mean concentrarion (FWMC) expressed as a mean of all sites was used for the annual load esrimarion calcularions as it most accurately reflects storm water loadings on an annual basis. The seasonal loadings were calculated from the pooled data using the median event mean concentration as there were too few data points from each watershed to use FLL7X to determine with a reasonable degee of accuracy a seasonal FWMC for each site. The median of the data set is a better representariott of the runoff data than the mean values (Bannerman et al., 1992). The annualload and a suwmation of the seasonal loads will not be equal due to this difference in calcularion methods.

Public Meeting on Tuesday, November 9�', 7:00-8:00 pm at Northwest Como Rec Center Gymnasium —1550 N Haznline Ave., St. Paul. The Capitol Region Watershed Distdct will hold an informa6onal meeting on November l and November 9`� to update the public on the Arlington Pascal Storm Water Improvement project, present the project components being considezed and respond to questions. Specific information that will be presented at the meeting includes: ♦ Update of studies completed; ♦ Schedule for the project; ♦ Descriprion of the storm water unprovements. The meeting will use the following format: 7:00 — 7:30 there will be an Open House with Display Boards with text and graphics; 730 — 8:00 Formal Presentafion describing the project with a question and answer session. The purpose of the meeting is to solicit comments regarding the storm water improvements under consideration, and to promote public understanding of the over all project goals. Project Update On June 30`� the CRWD conducted an open house to display and explain the three major components that the watershed district will be implementing for the Arlington Pascal Storm Water Improvement Project. At that meeting, many residents expressed concem over a proposed storm water pond to be located at the southeast corner �of Arlington and Hamline. Currently the watershed distdct is considering design altematives for the Arlington/Hamline ponding azea to address neighborhood concerns. (update con't on back) For more information visit o ur website at: www.capitolregionwd.org Project Summary Arlington Pascal Storm Water Improvement Project The Cities of St. Paul, Roseville and Falcon Heights along with Ramsey County and the Capitol Region Watershed District (CRWD) formed a partnership in 2003 to conduct an evaluation of the Como 7 Sub-Watershed. Now referred to as the Arlington Pascal Storm Water Improvement Project. This sub watershed of Como Lake is roughly bounded by Snelling Avenue on the west, Midway Pazkway on the south, Roseiawn to the north and Como Park on the east. The goals of the project were: 1) Reduce the frequency and duration of flooding in the sub-watershed and adjacent sub-watersheds because of Como 7 overflows; 2) Address needed improvements in the storm sewer pipes within the sub-watershed; 3) Improve water quality by reducing the amount of phosphorous tfiat reaches Como Lake; and 4) Detemune an equitable distribution of costs for any necessary improvements. (con't on back) Page 57 Appendix .,�rCin�ton/�1'ascaCStorm ZUater Project Summary (con't) �: g � � ;� J � A ��z� The results of the evaluation provided a plan to reduce the frequency and durarion of flooding in watershed and Midway Pazkway while at the same time improving water qualiry in Como Lake. �� ; j These goals are accomplished through an improved drainage system, = =� -----'��'�': f ponding azeas, rainwater gardens and infilharion trenches. ,.. ..,-� � I The watershed dish is now working with the City of St. Paul Public Works Department to plan and design several rainwater gazdens on McKinley St. and infiltration trenches along Arlington and Nebraska Avenues as part of the Arlington/Pascal Residential Sh�eet Vitality Program. In addition to these improvements, the CRWD is working with the Division of Pazks and Recreafion to construct water quality improvements in Como Pazk. (update con't from page 1) Any altemative design will still need to meet the overall project goals of reducing flooding and improving water quality while at the same time addressing neighborhood and Pazks concems. While many of the comments expressed at the meeting were directed towazds the proposed Arlington/Haniline pond, the watershed district did receive many favonble comments regazding the overall project. The watershed dishict will present altemative plans for the Arlington Hamline area. The distact is considering two altematives for the Southeast comer of Arlington and Hamline. One altemative is a pond on underground stormwater storage system.

S� Paul Water Quality Education Project 2004 Final Report Submitted by Friends of the Mississippi River November 2004 Storm Drain Stencilin� In 2004 Friends of the Mississippi River coordinated the stenciling of 2,431 storm drains and the dishibution of 9,192 doorhangers in partnership with 931 volunteers from school groups, community groups, and residents of the Ciry of St. Paul who stenciled for 2844 volunteers hours. A list of groups and event dates with goals aclueved is attached to this report. Storm drain stenciling was promoted using the following means: • Announcement at Center for Neighborhoods' teacher workshop at their January Sustainability Conference • Recruitment through Saint Pau) Public School (SPPS) Community Resource Specialists • Flyer and emailing to all SPPS teachers on FMR database • Flyer mailing to 2003 Children's Water Fesrival participants • Flyer mailing and phone call to Spring 2004 and Fall 2004 Big 12iver Joumey teachers • Mailing to Eco Education teachers • Mailing to teachers partnering with Sage Passi at Ramsey Washington Metro Watershed Dish • Mailing to SPPS's Fresh Force teachers • Posting on FMR's website, and announcements in FMR's email newsletter, Mississippi Messages • Announcement in the Metropolitan Council print & email newsletters Extra Education FMR staff made 31 extra education visits to 24 classrooms in nine public schools, two private schools, and three metro stormwater educarion events sponsored by WaterShed Partners The specific groups included: • Arlington High School (2 classrooms, 1 visit each) • Avalon School (4 classrooms, 1 visit each) • Farnsworth Aerospace Magnet (1 classroom, 2 visits) • Harding High School (4 classrooms, 1 visit each) • Johnson High School, (2 classrooms, 1 visit each) • St. Paul Open School, (3 classrooms, 1 visit each) • St. Paul Academy (1 classroom, 1 visit) • Talmud Torah School (1 classroom, 1 visit) • WaterShed Partners (3 stormwater education events) • Pazkway School (1 classroom, 1 visit) • Battle Creek Elementary (3 classrooms, 1 visit each) • Great River School (2 classrooms, 1 visit each) Page 75 Appendix . �., _; ._ `a Highlights: ' In March FMR staff did a presentation about rain barrels to fifth grade students at Farnsworth Aerospace Magnet. Afrer a slide presentation, FMR staff led a discussion about reducing run-off -., from residenrial lawns. In cooperation with staff at Ramsey Washington Metro Watershed District, FMR staff led a group of the same fifth graders in an outdoor rain gazden activity. Students determined a desirable rain gazden location in a residential lot by calcularing slope, measuring run-off azea, and testing soil type. Later that month, students planted a rain gazden in an east side St. Paul neighborhood and stenciled nearUy storm drains. FMR staff participated in a spring river cruise event that included Hazding High School students. After the cruise, and prior to a stenciling event at Harriet Island Park, students completed a mapping activity that involved calculating the amount of impervious surface in a given drainage azea. Students at Johnson $igh School learned about non point source pollurion in general, and the litter epidemic in particulaz during an April extra education visit. Students designed a campus litter reduction campaign that involved education, an increased number of trash receptacles, encouraging proper cigarette butt disposal by lughlighting butt bins, and rewarding students for proper disposal of recyclables. In May, FMR staff did a presentation at Johnson Hi� School about the river gorge and the role woody and herbaceous plants play in water quality and energy conservation. Students in cooperarion with school maintenance then planted several native wild plum trees on campus, donations from Minnesota DNR Forestry. Communitv Workshops FMR staff presented the watershed protection workshop Gardening for a Rainy Day: Native Plants, Rain Garderr.s, & Lawncare for Water Quality. Beth Storey, Watershed EducaUOn Coordinator, and Karen Schik, Restoration Ecologist, co-presented the workshops focusing on urban homeowner education. Alternative lawncare practices, landscaping with native plant species, the proper use of lawn fertilizer, rain barrels, backyazd composting, and soil testing were discussed using a slide presentation. Staff also in�oduced the concept of rain gardens and provided informarion about resources for homeowners interested in exploring this as an innovative stormwater management teclwique. A variety of printed materials and resource information was made available to participants to take home. The content was presented to 141 community members at seven workshops in St. Paul: • Mississippi Market Co-op, Selby location (2 workshops, 26 participants) • Ramsey County Master Gardeners composting workshops (3 workshops, 82 participants) • Living Green Ercpo (13 participants) • Hmong American Parinership (20 participants) Planning for the workshops included research on homeowner-installed rain gardens, rain gardens in clay soils, and mosquito control. Staff also met with a representaUve from a pervious paver company, interoiewed John Schmelz of Countryside Volkswagon who installed a pervious paver lot in Maplewood, took new slide photos for the presentarion, and collected a host of printed materials to be dish at the workshops. Participants for the workshop were recnuted using the following means: • A 600-piece postcazd mailing and emaiiing to selected horneowners on fhe FMK database • Announcement on the WaterShed Parhiers website Page 76 Appendix • Announcement on the Mississippi River Forum Items of Interest posting �'y �� E� �� • Emailing to all St. Paul neighborhood contacts �� - • Emailiug to all St. Paul city council members and planning districts "' `� • Posring on FMR's website and announcements in FMR's Mississippi Messages • Radio appearance on KFAI's Radio Antilles show =. • Press releases via faac and/or email to two daily and eight non-daily newspapers • Posting on MOEA's Next Step website • Posting on GreenSpace Partner's web announcement page • Posters in seven area coffee shops and three food co-ops Evaluation feedback from these workshops was overwhelmingly posirive. Participants often expressed that they felt inspired and morivated to make positive changes in their lawncaze practices. Sample evaluations from stenciling/education and workshop activities attached. Rain Garden Workshop Puttzng Down Roots — Rain Gardens in Residential Settings," was presented to forry-four participants in two sessions in September. On September 21 at the Virginia Street Church in St. Paul, Beth Storey gave a brief presentarion on non point source pollutants, followed by a ninety- minute presentation by Fred Rozumalski, RLA from Bazr Engineering. Mr. Rozumalski described what a rainwater garden is and how to build one, incorporating a"how to" approach that gave participants information about where a rainwater garden should be placed, soil preparation, plant selection and other elements of garden design and conshuction. The following week a bus tour visited two established rain gazdens designed by Mr. Rozumalski, and one recendy installed at Dayton's Bluff Elementary School. Staff from Ramsey County Soil and Water Conservation Dish also shared information about a cost-share program and available project assistauce for Ramsey County residents. Printed materials about rain gazdens were also available to workshop participants.
