Introduction: The Missouri Department of Natural Resources (MDNR) issued Phase II Storm Water Permit MO-R040005 to the (municipality name) and 60 other co-permittees in St. Louis County, effective March 10, 2003. The area served by the 61 co-permittees is collectively known as the St. Louis Metropolitan Small MS4. One of the minimum control measures in the permit that must be addressed by the co-permittees includes pollution prevention and good housekeeping for municipal operations. Specifically, section 4.2.6.1.1 of the permit (Appendix 1-A2) requires each co-permit tee to "develop and implement an operation and maintenance program that includes a training component and has the ultimate goal of preventing or reducing pollutant runoff from municipal operations." A Storm Water Management Plan (SWMP) for the St. Louis Metropolitan Small MS4 was developed by the St. Louis Municipalities Phase II Storm Water Planning Committee in the Fall of 2002 and submitted to MDNR as part of the application for the Phase II permit. As a co-permit tee under the state permit the City of Shrewsbury is bound by the commitments contained in the Plan. Chapter 14 of that Plan provided for organization of a municipal work group to develop a model operation and maintenance program to be adopted by each of the 61 co-permittees. This document represents the City of Shrewsbury adoption of the work group's model program as applicable and tailored to specifically meet Shrewsbury needs and goals. This program impacts all facets of municipal operations. It is the City of Shrewsbury intent to adhere to the policies and procedures stated herein in order to prevent pollution, to safeguard the environment for the health and benefit of all Shrewsbury employees, residents and visitors and to serve as a model for the entire regulated area. Where the municipal operations described in this manual are contracted, rather than performed by municipal employees, the best management practices (BMPs) will be imposed to the maximum extent practicable on the contractor through purchasing or contract mechanisms by including BMPs in the scope of work or job/service specifications. Contractors will be required to obtain all applicable local/state/federal environmental permits. This program has been adopted by (Resolution/Ordinance#2533) on (03-11-09), (See appendix 1-A4). B. Policies: The City of Shrewsbury has adopted several policies regarding the purchase of recycled products; janitorial and other supplies exhibiting lower toxicity; utilization of integrated pest management practices; and other pollution prevention policies. Copies of policies are contained in Appendix 1-61. C. Organization of Manual: The SWMP prepared for St. Louis County by the Planning Committee contains a detailed 9 listing of BMP elements that were to be considered when developing a model operation and maintenance program for the 61 co-permittees. The Planning Committee placed these elements into nine major categories of municipal operations/activities. Based on its size and the nature of its municipal services each co-permit tee may have activities in only some or in all nine categories. For consistency within the Plan area, each of the nine categories is addressed in the following Chapters 2 through 10. A statement of non-applicability is contained in those chapters where the (municipality name) is not engaged in the subject activity. REGARDLESS OF THE PRIMARY FUNCTION OF ANY PARTICULAR FACILITY, THE PLANNING COMMITTEE ANTICIPATED THAT ALL CHAPTERS MAY POTENTIALLY APPLY TO ACTIVITIES AT THAT FACILITY. FOR EXAMPLE AT A PARK MAINTENANCE FACILITY, THE MAINTENANCE OF PARKS MAY INVOLVE SOME ACTIVITIES THAT HAVE BEEN COVERED BY EACH OF THE OTHER CHAPTERS IN THIS DOCUMENT. THE HANDLING OF SUPPLIES WOULD BE SUBJECT TO GENERAL HOUSEKEEPING BMPs IN CHAPTER 2. THE MAINTENANCE AND CLEANING OF PARK EQUIPMENT, SUCH AS MOWERS, TRACTORS, TRUCKS, ETC., WOULD BE SUBJECT TO BMPS IN CHAPTERS 3 AND 4; CONSTRUCTION OR REPAIR OF FACILITIES, IN CHAPTER 5; MAINTENANCE OF PARK DRIVEWAYS AND PARKING AREAS, IN CHAPTER 6; CLEANING DRAINAGE CHANNELS AND STORM SEWERS, IN CHAPTER 8;AND MAINTAINING COMPOST PILES FOR MULCH, IN CHAPTER 9. MUNICIPALITIES ARE EXPECTED TO INCORPORATE ALL APPLICABLE BMPs FROM ALL CHAPTERS INTO PROCEDURES THAT APPLY TO ANY GIVEN FACILITY OR ANY GROUP OF EMPLOYEES TO ENSURE THAT EMPLOYEES ARE MADE AWARE OF ALL APPLICABLE BMPs. D. Administration: THIS SECTION SHOULD IDENTIFY THE CO-PERMIT TEE'S PROCEDURES AND THE STAFF RESPONSIBLE FOR ENSURING: THE PROGRAM IS KEPT UP-TO-DATE ALL AFFECTED EMPLOYEES ARE PROVIDED WITH PROGRAM ORIENTATION TRAINING RETRAINING AND DISCIPLINARY PROCEDURES FOR EMPLOYEES WHO FAIL TO FOLLOW THE SPECIFIED PROCEDURES REPORTING IMPLEMENTATION STATUS TO THE PLAN AREA COORDINATING AUTHORITY(MSD) The responsible party for administration of the operation and maintenance (O&M) program is the Director of Public Works. This person is responsible for ensuring the program is kept up to date, and that employees are trained on the procedures implementing the program. The City of Shrewsbury will train all staff associated with activities that can impact pollution in storm water runoff. Each chapter will identify employees who should be subject to training on that particular chapter. Employees will receive general storm water pollution prevention training provided by the Missouri Department of Natural Resources, Environmental Assistance Office or others. Upon implementation of specific procedures, management will review the new procedures that incorporate storm water BMPs, proper waste management and 1O applicable NPDES permit requirements with all employees affected. New employees will be trained on applicable procedures within the first three months of employment. Contractors working for the municipality and implementing BMPs for municipal work, as described in Section A., must train their employees on applicable BMPs before work begins. To maintain proficiency, a schedule of periodic retraining will be implemented, or provisions made for an employee awareness campaign to ensure employees remain aware of the BMPs and proper waste management. Records documenting the training of employees and contractors must be maintained in file. II Chapter 2 - General Housekeeping, Operation and Maintenance A. Description of Activities: Municipal operations include a variety of activities conducted to maintain City owned property and facilities. This chapter will cover those activities that are not specifically covered in the other chapters of this document. This chapter covers custodial and building maintenance activities, materials management and storage, safe material substitutions, spill plans, establishment of general O&M procedures, scheduling, record keeping and housekeeping practices in general. This chapter also covers general municipal housekeeping issues, which include illegal dumping, littering, pet wastes, trash storage, and recycling. B. Locations: 1. City Hall — 5200 Shrewsbury ave.

Best Management Practices (BMP): FACILITIES Pool drainage and filter backwash water from chlorinated swimming pools, fountains and lined ponds must be discharged into the sanitary sewer system. Other chlorinated water from water line or tank disinfection must also be directed to the sanitary sewer. Any discharge to surface water of pool or backwash water from pools and ponds must be de chlorinated prior to discharging into storm sewer system under the conditions of an NPDES permit obtained by the facility. The NPDES permit requires ceasing chlorination 7 days prior to discharge or using chemical de chlorination. These discharges to surface water must be approved under local building code, and not create a nuisance to adjoining property. Avoid using copper or silver-containing algaecides in pools, fountains and ponds. O Ensure grease traps and oil/water separators in kitchens and food service areas are maintained. Avoid sanitary sewer grease-blockage by regularly pumping out traps and separators. O Maintain site plumbing plans showing sanitary and storm sewer connections. Ensure wastewater is discharged only to the sanitary sewer, and storm water to the storm sewer. Label storm drain inlets to ensure they are used only for storm water drainage. • Minimize the use of pesticides through an Integrated Pest Management (IPM) Program. An IPM Program uses monitoring of pest populations compared to an action threshold, and then choosing the proper tactics, using nonchemical pest control practices, such as mechanical and biological controls, when possible, or less toxic products when needed. IPM does not rely on routine applications of pesticide based on a calendar date. 19 Reduce the risk of West Nile Virus by reducing stagnant water (mosquito breeding grounds) caused by cans, containers and tires present in litter and junk piles. Keeping storm water drainage gutters and drains clean will also reduce conditions suitable for mosquito breeding. Refer to MU Extension IPM Guides at: http://ipm.missouri.edu/ipmresources.htm (See Chapter 7 for additional BMPs.) Minimize the use of herbicides through an Integrated Pest Management Program for weed control. With turf grass, prevention of weed infestation begins with practices to promote healthy grass through proper planting, watering, fertilizing, mowing and thatch control. Refer to MU Extension Publication IPM1009: http://muextension.missouri.edu/xplor/agguides/pests/ipm1009.htm (See Chapter 7 for additional BMPs.) Reduce they,Recycle ti MATERIAL MANAGEMENT • Develop a policy to purchase recycled products or products with high post-consumer waste content whenever practical. Many resources are available from the EPA Waste Wise Helpline: 800 EPA-WISE. Website: http://www.epa.gov/epaoswer/non- hw/reduce/wstewise/wrr/buyq&a.htm (See Appendix 2-F1 for a sample waste reduction and recycling policy.) • Collect and recycle, to the maximum extent practicable, wastes generated by municipal operations. (See the policy in Appendix 2-F1.) • Develop policy to purchase environmentally preferred products whenever practical. For a "Database of Environmental Information for Products and Services," see EPA website: http://vosemitel.epa.qov/oppt/eppstand2.nsf/ (See Appendix 2-F2 for a sample green procurement policy or http://www.pwgsc.gc.ca/sd-env/sds2003/green-procurement-e.html). • Provide for the proper disposal of all wastes generated or collected in the course of municipal operations, in accordance with all applicable local, state and federal laws. • Inspect facilities for litter on a regular basis, and clean up as needed. • Keep trash container lids closed to keep rain out. Do not dispose of liquid waste in the trash container. • Ensure that the collection frequency of trash containers is appropriate to avoid overflows. 2U Outdoor material stockpiles at permanent location and at job sites should be covered to protect from rainfall and prevent contamination of storm water runoff. Material stockpiles which cannot feasibly be covered should be surrounded by a burm or otherwise contained so that storm water runoff can be captured. s Petroleum products, fuels, chemicals, hazardous and toxic materials, and all wastes should be properly labeled to ensure appropriate handling and disposal. c Petroleum products, fuels, chemicals, hazardous and toxic materials, and all wastes 21 should be stored and handled with appropriate safeguards to prevent contamination of storm water from drips and spillage from the transfer of materials (for example, cover storage containers, use collection trays for drips, maintain spill kits and floor drain plugs to contain spills, etc.). Liquid containers should be stored under roof; or if outdoors, containers should be kept clean and sealed water-tight• Prevent spills of hazardous materials by selecting storage areas that avoid traffic to minimize accidental contact, and select areas that are away from storm drain inlets and streams to minimize the impact of a spill. Storage areas should be kept clean and organized. . Contain and clean up all spills immediately. Ensure employees are familiar with spill response procedures and the location of spill kits to enable them to stop the spills at the source and contain the spilled material. With training on hazards from a material safety data sheet, minor spills can be addressed by employees, however, significant spills will require evacuation and contacting emergency responders. • Keep material safety data sheets (MSDS) for chemicals onsite for information on reportable spill quantities, proper handling, and health and safety issues. • Maintain and post a list of emergency contact numbers for spill reporting and spill clean-up contractor response, including: Missouri Department of Natural Resources (MDNR) — 573-634-2436, National Response Center— 800-424-8802, and for releases to the sewer, MSD — 314-768-6260. Reportable quantities (RQ) for chemicals are listed on the MSDS, and petroleum RQs include: any amount released to a storm sewer or waterway causing a sheen, 25 gallons from an underground tank, and 50 gallons from all other sources. • Prepare for appropriately handling the cleanup of the spilled material and disposal of waste. Do not hose down spills to the storm sewer system. Clean up spills with dry methods, using absorbent to pickup fluids. • Spill response plans are recommended for all areas of municipal operations. Spill Prevention Control and Countermeasure (SPCC) plans are required to meet regulatory criteria in 40 CFR 112 for sites with a storage capacity over 660 gallons oil in one container or 1,320 gallons on site. 22 a Establish at all municipal facilities materials management and inventory controls to include the proper identification of hazardous and non-hazardous substances, and proper labeling of all containers. Regular inspections and inventory of material storage and use areas should be performed to ensure BMPs are being used. COMMUNITY e Develop/enforce ordinances for waste containers which regulate size, type, covers and water-tightness for residential, ?3 commercial and industrial areas. (See Appendix 2-F3 for language from the St. Louis County Waste Management Code.) F Develop/enforce ordinances against illegal dumping, littering and improper yard waste disposal, providing for corrective action, enforcement and penalties. (See Appendix 2-F4 and 2-F5 for Model Ordinances.) • Develop/enforce ordinances requiring pet owners, property owners, and equestrian and animal boarding facilities to clean up wastes from their pets and other animals. (See Appendix 2-F6 for Model Ordinance). • Provide pet waste scoop dispensers and signage in parks and other public areas frequented by pet walkers to promote the proper disposal of pet waste and notify the public of ordinance requirements. • Provide recycling and yard waste services for residential waste. E Provide sufficient numbers of appropriately-sized waste receptacles at municipal facilities and in public areas with regularly scheduled servicing, collection and disposal. • Educate citizens on trash and pet waste issues to promote compliance with ordinances using available methods such as resident newsletters, brochures, internet sites, storm drain marking projects, etc. • Promote and assist in neighborhood and stream clean-up activities. • Develop/enforce municipal ordinances against illegal discharges to storm water from sources such as failing septic tanks, septic tanks discharging to storm water, etc. Ordinances to address illegal connections of sanitary sewers should be at least as stringent as the Missouri Department of Health regulations in 19 CSR 20-3 and County requirements, such as St. Louis County Plumbing Code Section 1103. • Develop/enforce municipal ordinances requiring the proper maintenance of septic tanks and other small onsite sewage disposal systems. For a model ordinance, see: http://www.aniec.org/htmllord-modelseptic.htm O&M PROGRAM • Establish standard operation and maintenance procedures, maintenance schedules and long term inspection procedures in accordance with this program manual with emphasis on safety, efficiency, and compliance with applicable laws and good environmental stewardship. • General housekeeping inspections of facilities and storage areas should be performed once a month and records kept of the inspections. • Develop record keeping procedures that effectively track implementation of program elements and that provide the information necessary to meet the reporting requirements of the MS4 permit. G. NPDES Permit status: N/A Applicable MDNR general storm water permits must be obtained if the city of Shrewsbury engages in the following activities described by the following categories: Airports (R8OF) — Storm water runoff from airports that use de-dicers or conduct uncovered vehicle maintenance, washing, or fueling. 24 EquipmentNehicle Washing (G75, See also Chapter 4) - Car wash wastewater treatment systems for design flows of 50,000 gallons per day or less. This includes no-discharge land application systems. Provides for 500 gallons per day de-minims exemption under certain conditions. Recycling facilities (R8OH, See also Chapter 9) - Solid waste transfer stations, and solid waste recovery facilities. Yard Waste compost facilities (G97, See also Chapter 9) - Yard Waste Composting operations between 2 to 5 acres. Solid Waste Transfer— requires a site specific storm water permit.

Inspect vehicles and equipment frequently for leaks, collecting leaks with pans or absorbent, and repairing leaks. • All routine vehicle maintenance and repairs at (Shrewsbury) facilities are performed indoors. On occasion and when necessary, outside maintenance work will be performed in a paved area with provisions made to contain and clean up all drips and spills. • Use non-hazardous, environmentally safe products when possible. Avoid use of chlorinated organic solvents. e Environmentally safe detergents are used instead of caustic cleaning solutions. e Flammable liquids are kept in a vented fire-rated cabinet. e All supply material and waste containers are marked clearly and properly to identify the contents. e Keep material safety data sheets (MSDS) for chemicals onsite for information on reportable spill quantities, proper handling and health and safety. D All supply material and waste containers are stored under cover to prevent contact with rainfall; or when uncovered, containers are clean and sealed. • 4 h • ., L. Tops of containers have absorbent mats and are free of standing liquid, and stored containers are kept closed. e Waste oils, filters, antifreeze, and other wastes are collected in designated, labeled containers and recycled to the maximum extent practicable. O Wheel weights are kept in a container marked "scrap lead". • Records of waste pick-ups are logged and maintained in file. • Drain pans are labeled for specific types of fluid. Use pans under vehicles and equipment with fluid leaks. Always use drip pans when making and breaking connections. 31 m Used oil filters should be gravity drained for 24 hrs with the anti-drain back valve or filter dome punctured to facilitate the draining process. Crushing the oil filter and recycling is preferred. Batteries, waste oil, etc. having spill/leak potential are stored indoors and are in secondary containment, when possible. F Neutralizer and absorbent are kept by both new and used batteries. o All floors are clean of oil and grease. ;? Immediately clean up all spills of chemicals or vehicle fluids using dry methods (absorbents), minimizing the use of water whenever possible. • Vehicle operators should be instructed to remain with the vehicle during fueling, and not to top-off the fuel tank to avoid overflows and spills. • For painting or sanding activities outdoors, use a tarp enclosure to contain and capture material. Collect and dispose of paint chips and sand blast waste in the trash for non- lead based paint, or evaluate lead based paint for hazardous waste disposal. • Keep the facility and surrounding area clear of litter. SPILL PREVENTION • Spill control plans should be in place with procedures for proper spill response to minimize environmental impacts. SPCC plans must meet regulatory criteria in 40 CFR 112 for sites with a storage capacity over 660 gallons oil in one container or 1,320 gallons on site. c Procedures for loading, unloading and transfer operations should be developed to prevent overfilling and spills. • In areas where spills could occur, such as fueling and loading areas, keep spill kits with absorbent materials nearby and display signage indicating the location of those spill kits. Storm drain plugs or covers are recommended to prevent the flow of spilled material from entering the storm drain. ® For fueling areas, post signs that state "no topping off'. • Regularly inspect all tanks and containers to ensure physical integrity. • Maintain equipment to ensure the proper operation of automatic shutoff devices on pumps and, overfill protection and spill buckets on tanks. O Emergency phone numbers are clearly posted in the shop and near material storage areas. FACILITY • Storm drains/inlets can be labeled to help protect from improper usage. • All above ground storage tanks have secondary containment in accordance with SPCC requirements and are covered with a roof. If containment is not roofed, inspect accumulated rain water for contamination prior to discharge. • Fueling areas are recommended to be designed with a roof to prevent contact with storm water. The area should be graded and sloped to direct storm water runoff away from the site and to prevent runoff from flowing over the fueling area. O Storm water treatment devices can be used to treat runoff from fueling areas. "No smoking" signs are posted in the shop, and near hazardous waste and flammable material storage areas. Verify that fire extinguishers are charged and inspected yearly. G. NPDES (National Pollutant Discharge Elimination System) Permit status: 33 Vehicle maintenance facilities of this type are considered "municipal industrial" facilities under the Missouri Storm Water Regulations and are subject to separate NPDES storm water (Phase I) permitting requirements under MDNR general permit R80C. As stated above, all of (municipality) vehicle repairs and maintenance are preformed indoors or are otherwise done without exposure to storm water. Therefore, a NPDES Storm Water permit is not required and a no-exposure certification has been filed with the Missouri Department of Natural Resources.

Never clean up concrete equipment or paint brushes and allow the washout into the street, storm drains, drainage ditches, or streams. F. Best Management Practices (BMP): FACILITY DESIGN • Consider designing facilities for "Low Impact Development" to reduce the volume and rate of storm water runoff from impervious areas to improve water quality. Refer to information on Low Impact Development from EPA's web site at: http://www.epa.gov/owowwtrl/NPS/lid/lidlit.html for more information about Low Impact Development methods. • In designing storm water drainage facilities, use the following BMPs, in accordance with MSD's storm water drainage facility design regulations, to improve the water quality of site drainage: wet detention ponds, wetlands, structural filter systems, grass swales, vegetative filter strips, and riparian buffers along streams. MSD's design regulations are contained in the "Rules and Regulations and Engineering Design Requirements for Sanitary Sewage and Storm water Drainage Facilities". Fact sheets on storm water management practices are available from the Storm Water Manager's Resource Center at the following web site: http://www.stormwatercenter.net O Carefully design and install plumbing and storm water systems to code, eliminating cross- connections between sanitary and storm drain systems. d Design material storage and handling areas to avoid rain and storm water runoff contacting stored material. • Design landscaping that uses native vegetation to reduce the need for irrigation, fertilizer and pesticide. LAND DISTURBANCE © Comply with St. Louis County or municipal land disturbance ordinances and programs implemented under the St. Louis County Phase II Storm Water Management Plan. For projects less than the land disturbance program thresholds, prevent erosion of soil from bare ground at the site by employing erosion and sediment control BMPs, such as: soil stabilization with mulch or seeding, settling basins, sediment traps, vegetated buffer strips, and silt fencing for perimeter controls. For details concerning these BMPs, see the SWPPP link on the following web page: www.stlouisco.com/plan/land disturbance.html 4 All construction or maintenance activities that excavate in or discharge any dredge or fill material into a "water of the United States" requires a Corps of Engineers 404 permit and a MDNR 401 water quality certification. Waters of the United States include ditches, creeks, rivers, lakes, ponds and wetlands. See Appendix 5-F1 for a summary of permit requirements. 39 CONSTRUCTION/REMODELING In accordance with city purchasing policies as stated in Chapter 1 and 2, every effort is made to purchase materials that are manufactured with recycled materials. Properly store materials as far away from storm inlets and streams as practical, and cover stored materials to avoid storm water impacts. Recycle or properly dispose of wastes, as indicated in Section E above. Never clean out or wash out paint or concrete mixers in the street or near a gutter, storm drain or stream. Small quantities of inert demolition wastes and construction scraps are disposed in the city hall dumpster. If larger quantities are generated, arrangements are made with a city- contracted hauler for a special pick-up. Keep work sites clean, pick up trash that can be windblown daily. Utilize certified asbestos inspectors to inspect floor tile, ceiling tile, fire-proof barriers and doors, roofing material and insulating materials for asbestos content prior to demolition. Manage material using certified asbestos personnel. Utilize certified inspectors to inspect for lead based paint on structures older than 1978. Use only state certified removal contractors for lead based paint abatement. When scraping or washing to remove non-lead based paint, collect paint chips in a tarp for proper disposal. Use water-based paint instead of oil-based paint whenever possible. Ensure that facility plumbing connects all sanitary wastewater discharges to the sanitary sewer, and that storm water is sent to the storm sewer system. G. NPDES Permit status: Land disturbance projects over 1 acre require a Land Disturbance Permit MO-R100A (if regulated under a Phase II compliant land disturbance program) or Permit MO-R101 from the MDNR. Storm water operating permits will not apply unless process water will be discharged to storm water and not to the sanitary sewers. H. Training: All employees involved in facility construction, facility repair and remodeling activities will be trained on the BMPs presented in this chapter. Personnel should be trained in the items noted below: General housekeeping Material storage, cleanup, and disposal Material reuse and recycling Equipment maintenance and cleanup Land disturbance erosion control Reduction of material for disposal through storage, reuse, or recycling can greatly reduce material and disposal costs, long term liability, preserve environmental quality, improve 40 workplace safety and provide a positive public image. 41 Chapter 6 - Cleaning and Maintenance of Roadways, Highways, Bridges and Parking Facilities A. Description of Activities: Most highway agencies and municipalities are responsible for the cleaning and maintenance of roadways, highways, and parking facilities under their maintenance purview. Activities include, but may not be limited to, street sweeping, flushing, applying surface seals, patching, snow removal, and emergency response to spills and accidents. Street sweeping operations normally involve self-contained and powered collection devices, utilizing belt conveyors or vacuum systems. This work may be performed on a scheduled basis, or when requested, and is usually conducted on roads with curbs where debris can accumulate in the gutter line. Many agencies flush bridge decks and parking structures in the spring to remove de-icing chemicals and to clean the drainage structures. Also, flushing operations are performed on sections of pavement where mud or debris accumulates after flooding, creating hazardous conditions. Bridge decks and parking structures are normally sealed on a five-to-seven year cycle to protect the concrete and steel reinforcement from corrosive elements. Patching operations involve the preparation of potholes and the fill of either hot mix or cold patching material. Highway agencies plow and salt the roadways under their maintenance jurisdiction during winter snow events. Typically, 200 to 400 pounds of salt per lane mile is used to de-ice the pavement. Other chemicals, such as calcium chloride, are used when prevailing temperatures fall below 20° Fahrenheit. Most highway agencies are required to respond to emergency situations involving spills and debris from vehicles. This work is performed if it is determined that the material which will be removed from the public road right-of-way is of a non-hazardous nature. Hazardous material is handled through hazardous material removal procedures not specified in this chapter. B. Locations: All road networks or public parking lots of the City of Shrewsbury. C. Responsible Parties: 42 The responsible parties involved in the cleaning and maintenance of streets and parking lots include: Public Works Staff. D. Materials/Supplies Acquisition, Storage and Usage: Large quantities of materials are expended in the performance of work. Some material is purchased and used immediately, while other material is stockpiled. Agencies working within the constraints of their budget weigh fiscal responsibility against the immediate and long- range needs for such materials, and adjust their purchasing habits accordingly. Maximum Material Quantity Kept On For Use Within Storage Location Hand Salt (Sodium Chloride, Calcium Up to 600 tons One Year Public Works Chloride) Aggregate(various sizes) Up to 30 Tons Yearly Public Works Cold-Patching Material Up to 5 Tons Yearly Public Works Hot Mix Asphalt Purchased When Daily y Deck Sealing Materials Up to 5 Gallons As Needed Public Works Topsoil Purchased When Yearly y Concrete Ready-Mix Purchased When Daily y Concrete Bag Mix 4 bags One Season Public Works E. Waste Generation, Storage, Disposal, Recycling: A certain amount of construction spoil and waste is generated during the performance of maintenance operations on our road network. Recycling methods are employed if they are determined to be cost-effective; however, in many instances, waste material must be removed from the work site by various disposal methods. 43 Maximum Storage Waste Storage Location Method Of Disposal Frequency Capacity Asphalt Millings Unlimited Recycling We take all Asphalt and Asphalt As from Co-Planning Storage Plant millings to the recycling plant Generated Operation Options Unlimited Recycling We take all Concrete to the As Concrete Rubble Storage Plant recycling plant Generated Options Trash, Grit and Debris from Unlimited Recycling We pick out the trash the best As Street Sweeping Storage Plant we can and recycle the rest with and Road Clean Options the compost.

Best Management Practices (BMP): 44 MAINTENANCE • If certain road maintenance activities are prone to produce pollutants that can be carried off with storm water runoff, schedule these maintenance activities during times of dry weather if possible. • Capture scrapings/rust/dirt/sandblasting grit/over spray/drips, etc., from preparation and painting of bridges/structures/traffic control devices. • For steel girders on bridges, utilize certified inspectors to inspect for lead based paint on structures older than 1978. Use only state certified removal contractors for lead based paint abatement. 45 Used asphalt is recycled when it is cost-beneficial. • Block scuppers and drains when sealing bridge decks. c On asphalt overlays, ensure storm water drainage capacity of curbs and inlets is maintained by milling down into the street at the curb, or using open graded thin bonded overlay. • Comply with St. Louis County or municipal land disturbance ordinances and programs implemented under the St. Louis County Phase II Storm Water Management Plan. For projects less than the land disturbance program thresholds, employ BMPs for erosion and sediment control. • All construction or maintenance activities that excavate in or discharge any dredge or fill material into a "water of the United States", which includes ditches, creeks, rivers, lakes, ponds and wetlands, requires a Corps of Engineers 404 permit and a MDNR 401 water quality certification. Examples of construction or repair activities requiring a permit include: bridge work, culverts under road crossings, dredging or placing rip rap in creeks. See Appendix 5-F1 for a summary of permit requirements. DE-ICING F.. Aw' K Use calibrated chemical applicators for salt and brine applications when equipped. i Minimize the use of salt without compromising public safety. Stop salt feed on trucks at stop signs, lights, ect. Stored salt is on an impervious surface and is covered. • As available, use road weather information such as weather forecasts, meteorological data, and pavement sensors to maximize the efficiency and effectiveness of resources. CLEANING • Remove as much mud, grit, salt and debris as possible (by scraping, sweeping, etc.) prior to roadway flushing on bridges ect. 46 Evaluate the need for street sweeping to remove grit and trash at facility parking lots and roadways within jurisdiction. Implement street sweeping, when feasible, focusing on heavy traffic patterns, seasonal variations (spring/fall), and problem areas. Record the volume of trash/debris removed to identify the priority of areas being cleaned and the effectiveness of resources used. Investigate to determine sources of litter in areas of excessive accumulation. ® The environmentally preferred sweepers are those with an integral collection device and fugitive dust control. Properly dispose of trash/debris as indicated in Section E above. c Do not hose down parking lots in a manner that discharges wash water to the storm drain untreated. G. NPDES Permit status: Not Applicable H. Training: Employees involved in Street and Highway maintenance and repair will be trained on the BMPs in this chapter. -17 Chapter 7 - Maintenance of Parks, Green Spaces, Trails and Landscaping A. Description of Activities: The (City of Shrewsbury) has 4 parks totaling nearly 30 acres of land, and over 2 miles of biking, hiking and jogging trails. The City of Shrewsbury has responsibility for the development and maintenance of recreational areas and green space within the city, including neighborhood and regional parks, community gardens, bike and walking paths, trees, public facility landscaping and public street right-of-way landscaping. The city promotes an interconnected system of open space and trails that facilitates active and passive recreational opportunities for the community. The creation and design of parks and open space can assist in management of storm water by providing green infrastructure and a means of absorbing rainwater, slowing its release in to streams, storing, filtering and slowing storm water runoff down and thus preventing or reducing flash flooding downstream. Local governments have an opportunity to use their park lands to benefit the environment and to demonstrate best practices for storm water management. Maintenance activities include mowing of grassy areas, pruning trees, removing fallen limbs, mulching, emptying trash receptacles, trail maintenance (repairing asphalt bike path and walking trails), routine cleaning of park restrooms, and parking lot maintenance. B. Locations: Wehner park 5200 Shrewsbury ave. Hartry park 4115 Exeter ave. Brinkop park 4810 Laurella ave. Ackfield park 7400 Sutherland ave. Green spaces are interlaced throughout the community and are maintained by the Public works Department and local volunteers. C. Responsible Parties: The Director of Public Works has authority over all parks Maintenance. Parks are actively managed by the Director of Parks and recreation. Volunteers donate their time to assist in park beatification. D. Materials/Supplies acquisition, storage and usage: The following materials and quantities are typically kept on hand for landscaping and park maintenance operations. 49 Maximum Material Quantity Kept On For Use Within Storage Location Comments Hand Mulch Pile 10 yd 12 Months Concrete Pad Fertilizer 0 Bags As Needed Garage Herbicide 10 Gallons 6 Months Garage Rock 30 Tons 1 Year E. Waste generation, storage, disposal, recycling: Wastes generated by landscaping and park maintenance operations are as follows. Maximum Storage Method Of Waste Storage Location Disposal Contractor Frequency Capacity Wood, brush 20 yd Public Chip into works Mulch Public works 12 Months Leaves, Grass 100 yd Public Recycle as works compost Public works 12 Months F. Best Management Practices (BMP): PARK DESIGN AND SITING a Creating undeveloped, natural open space and preserving established trees and other natural vegetation, particularly around natural drainage areas, such as creeks, is recommended. Tree buffers and tall grass filters around streams improve water quality, slow runoff and prevent erosion. A minimum buffer width of 50 feet is recommended. © Avoid site development and placing facilities in the flood plain. • Design park sites to preserve natural resources such as wetlands and existing natural draining areas, minimizing their loss and maintaining existing trees and a riparian corridor next to creeks to the degree possible. Minimize creek crossings, and place them only after consideration of the stream features to enable natural flow. a Design landscaping that uses native vegetation to reduce the need for irrigation, fertilizer and pesticide. Select plants appropriate for site conditions for sun, moisture, and soil type. • Utilize low impact development to minimize impervious surfaces, See Chapter 5. • In designing storm water drainage facilities, use the following BMPs to improve the water 50 quality of site drainage and slow the release of water to streams: wet detention ponds, micro detention basins, wetlands, rain gardens, vegetative filter strips and riparian buffers along streams, structural filter systems, pervious pavement and green (vegetated) roofs. The use of swales instead of curbs along roads and parking lots is beneficial to filter pollutants and reduce the volume and rate of storm water flow. Fact Sheets on storm water management practices are available from the Storm water Manager's Resource Center at the following web site: http://www.stormwatercenter.net COMMUNITY PROGRAMS • Sponsor activities and annual events that involve the general public, schools, watershed groups, stream teams, etc., providing hands-on activities that promote water quality in their adopted parks and greenways. Typical activities include: field trips, cleanups, educational programs, restoration projects, stream monitoring, storm drain marking, and trail projects. e Organize or participate in reforestation programs, planting native trees to buffer streams, create shade, and beautify parks. Support community volunteer group efforts in these programs. • Require pet owners to pickup and properly dispose of pet waste in parks. Provide pet waste scoop dispensers and signage in parks to notify visitors of the requirement. PARK/LANDSCAPE MAINTENANCE • Remove litter and debris regularly. • Properly dispose of yard waste, for example, by composting. Do not dump yard waste into creeks. • Minimize mowing of open space sites, depending on site objectives. • Mow grass higher and leave grass clippings on the lawn to retain moisture and provide nutrients. • . L . Remove exotic invasive vegetation and replace with native plantings as resources are available. • Perform soil tests to determine the optimum fertilizer application rate. • • Apply fertilizer only in cool weather, preferably fall. Avoid application before a rain, and do not apply fertilizer at rates higher than indicated in on label instructions. Apply slow release fertilizers such as ethylene urea, IDBU or resin coated fertilizer. 5I When disturbing land, such as clearing vegetation and destroying the root zone, employ BMPs for erosion and sediment control. For details concerning these BMPs, see the SWPPP link on the following web page: www.stlouisco.com/plan/land disturbance.html • All construction or maintenance activities that excavate in or discharge any dredge or fill material into a "water of the United States", which includes ditches, creeks, rivers, lakes, ponds and wetlands, requires a Corps of Engineers 404 permit and a MDNR 401 water quality certification. Examples of activities that require a permit include: placing culverts in creeks, constructing outfalls, and stream restoration activities. See Appendix 5-F1 for a summary of permit requirements. INTEGRATED PEST MANAGEMENT • Use Integrated Pest Management (IPM) techniques to minimize the use of pesticides. Pesticide application should be timed carefully and combined with other pest management practices. Pests and their development stage should be identified accurately and pesticide applications made only when necessary, using the least amount needed and the least toxic product for adequate pest control. • Use mechanical controls to keep pests in check, such as species specific, pheromone based traps. Remove pests by hand. Eliminate conditions favorable to pests and place barriers to control pests and weeds. • Use natural, biological controls, when feasible, including natural enemies of pests, such as: predators, parasites, pathogens, pheromones, and juvenile hormones. • Reduce the risk of West Nile Virus by reducing stagnant water (mosquito breeding grounds) caused by cans, containers and tires present in litter and junk piles. Keeping storm water drainage gutters and drains clean will also reduce conditions suitable for mosquito breeding. Refer to MU Extension IPM Guides at: http://ipm.missouri.edu/ipmresources.htm • Minimize the use of herbicides through an Integrated Pest Management techniques for weed control. This includes practices that keep plants healthy, such as selecting disease and pest resistant varieties and maintaining good growing conditions. For turf grass, prevention of weed infestation begins with practices to promote healthy grass through proper planting, watering, fertilizing, mowing, aerification, and thatch control. Refer to MU Extension Publication IPM1009: http://muextension.missouri.edu/xplor/agquides/pests/ipm1009.htm PESTICIDE/HERBICIDE USE • When pesticide or herbicide use is required, select pesticides carefully, avoiding highly water soluble and very environmentally stable products to minimize potential for leaching from soils into waterways. Environmentally friendly products readily degrade in the environment and/or bind to soil particles. • Consider the vulnerability of the area in which pesticides are applied, avoiding areas with streams, ponds, sinkholes or wells. Sinkholes are an environmentally sensitive area because they allow surface water to reach groundwater quickly with little natural soil filtering. 52 e Apply pesticides when the target pest is at its most vulnerable life stage, and use site specific rather than wholesale application. e Read pesticide labels carefully for information and restrictions about the rate, timing, and placement of the pesticide in that container. Calibrate equipment to apply at the proper rate. Apply when the threat of rain is low to avoid wasting material and washing pesticide into the waterways. Carefully calculate how much pesticide concentrate is needed to treat the specific site with the equipment being used, to eliminate disposal of excess spray mix. • Store pesticides in their original containers in a cool, well-ventilated building with a concrete floor. Handle pesticides carefully to avoid spills. • Dispose of pesticide waste properly, following label instructions. G. NPDES Permit status: Not applicable H. Training: All employees directly involved in the design, construction and maintenance of landscaping, trails, green spaces and parks will be trained on the BMPs in this chapter. Affected employees will likely be: facility engineers, park management, equipment operators, gardeners, laborers, and contract operations providing these services. Chapter 8 - Cleaning and Maintenance of Drainage Channels, Storm Sewers and Inlet Structures A. Description of Activities: The storm drainage system functions to collect and convey surface runoff to receiving waters during storms in order to prevent flooding. The system consists of improved and unimproved drainage channels, culverts, bridges, trench drains, gutters, ditches, swales, storm sewers and storm inlet structures. Maintenance of the system is necessary to ensure it functions hydraulically as intended. MSD has the major responsibility for the cleaning and maintenance of improved channels and storm sewers in the Plan Area. Maintenance responsibilities are defined in MSD's "Statement of Policy for Maintenance of Storm water Sewer Systems and Facilities". Many of the co-permittees are responsible for maintaining the storm sewer systems on their property, and on systems not dedicated to the MSD system. In addition, municipalities are responsible for maintaining bridges, storm culverts, ditches and gutters along the streets in their city. MSD does maintain road inlets and culverts on systems dedicated to MSD. MSD does not maintain detention and retention basins or yard swales. Maintenance of basins and yard swales is the responsibility of property owners, as addressed in MSD's "Rules and Regulations and Engineering Design Requirements for Sanitary Sewage and Storm water Drainage Facilities". B. Locations: The (MSD) separate storm system includes XX miles of storm sewers and YY miles of open natural drainage ditches and channels. All structures are identified on facility base maps. The number of catch basins on the separate storm system is approximately ZZ. Generally, the inlets on the storm system are not constructed with traps to capture oil, grease or debris. C. Responsible Parties: Metropolitan St. Louis Sewer District Director of Operations. Yard, Operations Manager. Municipality Public Works Department, Director, Telephone: (314) 645-7441 D. Equipment/Materials/Supplies acquisition, storage and usage: City of Shrewsbury Public Works Department has (1) Street Sweeper to help maintain the inlets. E. Waste generation, storage, disposal, recycling: 56 Wastes generated from maintenance of the storm drainage system must be disposed of properly, as indicated in the table. All waste being disposed of in a landfill must not contain free liquid. Water draining from waste destined for a sanitary landfill is considered wastewater and must be disposed of in a sanitary sewer system.

Best Management Practices (BMP): GENERAL e Within budgetary constraints and responsibilities, perform preventative maintenance of the storm drainage system to remove flow obstructions to reduce flooding and erosion problems and improve water quality. • Utilize care in cleaning catch basins, storm sewers and drainage channels, to properly collect and dispose of waste as indicated in Section E to minimize contaminants discharged into storm water. Note in the work order the volume of waste collected and disposed of. Investigate into the source of increased maintenance needs, if excessive. When possible, focus cleaning efforts before rainy seasons. • If storm inlets/catch basins, storm sewers and drainage channels are impacted by non- storm water discharges or illegal dumping of waste, contact MSD, Division of Environmental Compliance at 314-436-8710 for investigation and enforcement. • Implement Phase II public education efforts; public participation efforts to mark inlets 57 with "No Dumping, Drains to Stream"; or organize public stream clean-up events. • Identify failing detention or retention basins and report them to MSD Customer Service at 314-768-6260. • Comply with St. Louis County or municipal land disturbance ordinances and programs implemented under the St. Louis County Phase II Storm Water Management Plan. For projects less than the land disturbance program thresholds, employ BMPs for erosion and sediment control. - o rat k - r : Ate " ' t t 7r' CATCH BASINS (MSD) • Prioritize catch basins for routine maintenance on a specified frequency based on need. Identify areas for additional maintenance to coincide with litter from major public events, and based on work orders generated by customer complaints and/or flooding. Increase maintenance of inlets that are fully blocked or 75% full of trash or debris when maintained. Reduce maintenance of catch basins that do not result in waste generation. • Consider installation of catch basin inlets in areas where storm sewers will be known to receive excessive amounts of litter or sediment. STORM SEWERS (MSD) • Prioritize storm sewers for routine maintenance on a specified frequency based on flat grades, low flow, or review of work orders. Identify areas for additional maintenance based on work orders generated by customer complaints and/or flooding. G Utilize care in cleaning storm sewers by flushing, to properly collect waste using debris/sediment traps. • Seal/repair joints in structures to prevent root intrusion and soil wash-out. • Minimize or avoid the use of chemical root/vegetation killers, and use the least toxic alternatives when necessary. DRAINAGE CHANNELS (MSD) • All construction or maintenance activities that excavate in or discharge any dredge or fill material into a "water of the United States", which includes ditches, creeks, rivers, lakes, ponds, and wetlands, requires a Corps of Engineers 404 permit and a MDNR 401 water quality certification. Examples of construction or repair activities requiring a permit include: sewer creek crossings, outfall structures, stream bank stabilization, and all channel modifications. See Appendix 5-F1 for a summary of permit requirements. Consider downstream conditions prior to spot channel stabilization efforts to avoid 58 simply moving problems downstream. Revegetate stabilized areas with native plants whenever possible, and as soon as possible. MSD's Division of Environmental Compliance will inspect all open drainage channels under its Illicit Discharge Detection Program, and will notify MSD's Operations Department, St. Louis County, the municipality or MoDOT, as applicable, regarding maintenance needs concerning damaged structures or blockages requiring removal. MUNICIPAL DETENTION BASINS 6 Existing control structures undergoing renovation are modified to the maximum extent practicable to meet new construction criteria in MSD's "Rules and Regulations and Engineering Design Requirements for Sanitary Sewage and Storm water Drainage Facilities". O Inspect facilities to insure proper operation and maintain as needed, including: trash and debris removal, vegetation control, vector control, structural and erosion repair, and sediment removal to restore capacity. G. NPDES Permit status: Not applicable H. Training: MSD collection system operators, contractors and municipal employees involved in maintenance of drainage systems will be trained on the BMPs in this chapter. i9 Chapter 9 - Operation and Maintenance of Recycling and Composting Facilities (NOTE: FOR THE PURPOSES OF THIS CHAPTER, RECYCLING INCLUDES YARD WASTE/MULCHING/COMPOSTING OPERATIONS AS WELL AS SITES COLLECTING COMMON HOUSEHOLD RECYCLABLES SUCH AS(PAPER, PLASTIC, GLASS, CARDBOARD, ETC, THIS IS OPEN TO THE PUBLIC) A. Description of Activities: The material collected at the recycling depository includes a variety of materials such as paper, plastic, glass, aluminum, steel, and Christmas trees (January-February) B. Locations: The facility is located at 7309 Melbourne ave. The site consists of 3 acres. The site is fenced and paved for the general public use of the site for recycling. C. Responsible Parties The Public Works Director has authority over the facility. The facility is actively managed by the City's Public works Director and other Public Works employees. Director of Public Works, Telephone (314) 645-7441 D. Materials/Supplies acquisition, storage and usage: Recyclable materials are delivered directly to designated, labeled storage areas. Only collected recyclable materials are kept on site until a significant quantity is obtained for shipping. Trash and waste is removed from the site by attendants and not allowed to accumulate. The following materials and quantities are typically stored onsite: Maximum StorageShipment Recyclable Quantity Location Contractor Method Frequenc Stored y Yard Waste, Brush, 100 Yards Yard Cit Compost, Grass Clippings, Wood y Mulch Steel, Tin Cans 20 Yards Yard City 20 yard box As Needed Aluminum Cans Same Paper—Newspaper, 40 Yards Yard City40 and box As Phone Book y Needed Catalogs, Magazines Same 60 Mixed Paper(junk mail, boxboard, office paper, computer Same paper) Corrugated Cardboard Same Plastic Bottles Same (#1 and#2) • Glass Same Textiles (old clothing, draperies 0 or linens) E. Waste generation, storage, disposal, recycling: A small amount of waste is generated by the public. Residents bring their recyclables to the facility in non-recyclable containers and then leave the non-recyclable container (often, plastic bags) behind. This small amount of waste is removed by attendants and disposed of in sanitary trash containers. No dumping or disposal of trash is otherwise allowed on the site. F. Best Management Practices {BMP): Yard waste composting operations and mulch piles should be located away from storm water drainage systems, and must not be located within 100 feet of a natural creek or man-made storm water drainage channel, 300 feet from a water well or 1,000 feet from a sinkhole, under MDNR permit G97. Compost/mulch is confined by an impervious base with curbing or otherwise stored to prevent leachate and runoff from contaminating storm water, and to prevent storm water drainage running into the pile. Do not discharge leachate to storm water. As necessary to manage leachate, design a system to collect and properly treat leachate or incorporate into the early stages of the composting process. Materials that will pollute storm water are collected under a roofed structure or in an enclosed dumpster. The public is notified by signage at the facility that lists materials accepted at the facility and those unauthorized items that are not acceptable. Attendants are on duty to monitor use of the facility and to ensure unauthorized items are not deposited by the public. The Police Department routinely patrols the facility to prevent unauthorized dumping. No fluids are drained into any storm water system. Every effort is made to ensure the facility is clean and that no unauthorized or contaminated materials are deposited at the facility. Materials easily moved by wind must be stored in a manner to prevent the material from 61 becoming airborne and scattered. An emergency phone is available at the site for attendants to promptly report any problems to the supervisors or the Police. Drums or containers of oil, petroleum products or hazardous materials are not accepted. Also drums or containers that have previously contained these substances are unacceptable for recycling at the facility. G. NPDES Permit status: 1. Recycling Center: Facilities involved in the recycling or composting of materials are considered "municipal industrial" facilities under Missouri Storm Water Regulations and are subject to separate NPDES Storm Water (Phase I) permitting requirements, unless they are collection points only and completely protected from storm water (run-on and run-off). Potentially applicable MDNR NPDES General Permits include: R8OH for Recycling facilities and G97 for Yard Waste Compost sites. As noted above, all of the city's recyclable collection and handling activities are conducted indoors or are otherwise conducted without exposure to storm water. Therefore, an NPDES Storm Water permit is not required for the Recycling Center. A "no-exposure certification" has been filed with the Missouri Department of Natural Resources.(No permit is required per MSD) H. Training: All City employees attending to the operation or using the recycling and composting facility will undergo initial City-provided training upon employment. All employees are regularly instructed on the use of equipment and handling of problem situations. Chapter 10 - Water Quality Impact Assessment of Flood Management Projects A. Description of Activities: New flood management projects located within the co-permittees jurisdiction must be assessed for impacts on water quality. Existing projects must be assessed for incorporation of additional water quality protection devices or practices, where feasible. Flood management projects in the Plan Area can include: regional storm water control (retention basins, detention basins); flood control levees and associated pump stations; storm water drainage conveyance capacity improvements; projects involving land buyouts; and designated uses of flood plain land. Storm water management projects in both development and re-development will be assessed for water quality impact, according to MSD's "Rules and Regulations and Engineering Design Requirements for Storm water Drainage Facilities", which address the Storm Water Management Plan water quality requirements under MCM 5. Projects within designated levee districts, such as Monarch-Chesterfield, Earth City and Riverport will be based on the Storm Water Master Plan for these districts. All flood management projects involving channel modification will also be assessed for aquatic and water quality impacts through the Corps of Engineers 404 permit and MDNR 401 water quality certification process. B. Locations: Existing projects located within the Plan Area include: C. Responsible Parties: All co-permittees that plan, design or install flood management projects are subject to this chapter. MSD has general responsibility for storm water drainage facilities in the Plan Area. St. Louis County, municipalities, and property owners have responsibility for the drainage facilities not dedicated to, and maintained by MSD. St. Louis County and municipalities maintain control over planning and zoning, land use regulations, and flood plain management through ordinances. D. Materials/Supplies acquisition, storage and usage: Not applicable. For construction phase of work, land disturbance requirements will apply. See Chapter 2 and 8 for construction and maintenance. E. Waste generation, storage, disposal, recycling: Not applicable. See Chapter 2 and 8 for maintenance. F. Best Management Practices (BMP): 64 • Implement and enforce ordinances and/or procedures requiring that water quality factors be incorporated into the design and operation of storm water/flood control structures. G Inspect existing flood management facilities on a specified frequency to determine water quality impacts and exploit opportunities for improvement. e Existing control structures undergoing renovation are modified to the maximum extent practicable to meet new construction criteria in MSD's "Rules and Regulations and Engineering Design Requirements for Sanitary Sewage and Stormwater Drainage Facilities". • Design new flood management projects to prevent or minimize adverse water quality impacts, exploring alternative programs utilizing non-structural flood damage reduction and stream bank stabilization measures to the maximum extent practicable, such as flood proofing houses, and buy outs. e Use models based on fully developed conditions, and adopt a free board above base flood elevation for development. • Identify existing wetlands or other natural open space areas, particularly around streams, and preserve them from development so they can provide natural attenuation, retention or detention of runoff. • Survey watersheds downstream from proposed projects to determine potential water quality impacts. Design proposed projects to minimize downstream impact. • Work closely with local governments, environmental organizations and others to develop multi-use open space corridors along streams which will allow for overbank floodplain storage. • Floodplains are preserved to the maximum extent practicable. • Use non-structural flood management practices to the maximum extent practicable, utilizing acquisition of flood-prone property where possible. • Open storm water conveyance systems are used to the maximum extent practicable to preserve natural conditions and habitat. • Channel improvement projects are to use natural approaches rather than concrete, riprap or other "hard" techniques to the maximum extent practicable. • Inlets and outlets from closed portions of conveyance systems are designed to minimize scour and erosion. • Trash racks are provided at outlet structures of detention ponds and other flood control structures to capture trash and floatables. • Employ natural solutions and use controls that preserve the hydrology of a site as a first line of flood control to the maximum extent practicable. G. NPDES Permit status: Not applicable H. Training: 65 •, Employees and contractors responsible for the planning and design of the flood management projects identified in Section A will be trained on the BMPs in this chapter. In addition, employees performing this work will be familiar with MSD's rules and regulations and engineering design requirements for storm water drainage facilities.

Other Permit Sections Pertinent to MCM #6 The following four sections contain pollution control requirements specifically for municipally owned facilities and were, therefore considered when drafting the O&M Program under MCM #6. 4.1.1.2 For facilities under the control of the permittee good housekeeping practices shall be maintained to keep solid waste from entry into waters of the state to the maximum extent practicable. 4.1.1.3 All fueling facilities under the control of the permittee shall adhere to applicable federal and state regulations concerning underground storage, above ground storage, and dispensers, including spill prevention, control and counter measures. 4.1.1.4 Substances regulated by federal law under the Resource Conservation and Recovery Act (RCRA) or the Comprehensive Environmental Response, 73 Compensation, and Liability Act (CERCLA) that are transported, stored, or used for maintenance, cleaning or repair by the permittee shall be managed according to the provisions of RCRA and CERCLA. 4.1.1.5 All paint, solvents, petroleum products and petroleum waste products (except fuels) under the control of the permittee shall be stored so that these materials are not exposed to storm water. Sufficient practices of spill prevention, control, and/or management shall be provided to prevent any spills of these pollutants from entering a water of the state. Any containment system used to implement this requirement shall be constructed of materials compatible with the substances contained and shall also prevent the contamination of groundwater. Other provisions of the permit also were considered in developing the municipal O&M program. MCMs #3 (Illicit Discharge Detection and Elimination), #4 (Construction Site Storm Water Runoff Control) and#5 (Post-Construction Storm Water Management in New Development and Redevelopment) all can apply to activities conducted by the municipal co- permittee at municipally owned projects. While the permit requirements for these MCMs are primarily geared toward the municipal co-permittee exerting control over these activities by the people living and working within the municipality, logically similar controls must be applied to municipal activities of the same nature. The municipal co-permittees must ensure that there are no illicit discharges from municipal facilities, that there are runoff controls in place for municipal land disturbance projects and that storm water management provisions have been considered for new or redeveloped municipal properties. 74 Glossary: Definitions of Terms Used In This Document The following definitions are specific to the St. Louis Metropolitan Small MS4 and to the (municipality). Best Management Practice (BMP) means: Schedules of activities, prohibitions of practices, maintenance procedures and other management practices to prevent or reduce the pollution of streams within St. Louis County from urban runoff. BMPs also include treatment requirements, operating procedures and practices to control site runoff, spillage or leaks, sludge or waste disposal or drainage from raw material storage. BMPs may be structural or non-structural. (This definition adapted from Section (1)(C)1 of Missouri Storm Water Regulation 10 CSR 20-6.200) Coordinating Authority means: The municipal entity, which is one of the co-permittees to a state issued Phase II storm water permit, that is recognized by the Missouri Department of Natural Resources (MDNR) as the party which will coordinate the activities of all of the co- permittees in meeting the requirements of the permit. For the St. Louis County Plan Area, the Metropolitan St. Louis Sewer District (MSD) has been identified in the permit as the coordinating authority for the 61 co-permittees. One of the coordinating authority's responsibilities is to prepare and submit an annual report to the MDNR on the status of compliance of all 61 co-permittees with the permit and approved SWMP. Co-permittee means: An individual permittee named in a Phase II permit that is issued to multiple entities within a single urbanized area such as St. Louis County. Within the St. Louis County Plan Area, each of the 61 co-permittees, is responsible only for the permit conditions relating to the discharges for which it is the owner or operator and for carrying out the responsibilities for which it has been designated within the SWMP. The co-permittees share in the financial and administrative responsibilities under the permit and cooperate with each other and with the coordinating authority in complying with the terms of the permit and with meeting the commitments in the SWMP. The co-permittees are listed in Appendix 1-Al. Green Procurement - the procurement of products and services that have a lesser or reduced effect on human health and the environment when compared with competing products or services that serve the same purpose. Green Product— a product that is less harmful than the next best alternative, having characteristics such as: ® Being recyclable. • Being biodegradable. • Containing recycled material (post-consumer recycled content). • Having minimal packaging and/or for which there will be take-back by the manufacturer/supplier of packaging. n Being reusable or contain reusable parts. • Having minimal content and use of toxic substances in production. • Producing fewer and/or less polluting by-products during manufacture, distribution, use and/or disposal. 107 Producing the minimal amount of toxic substances during use or at disposal. d Making efficient use of resources - a product that uses energy, fuel or water more efficiently or that uses less paper, ink or other resources. Being durable or having a long economically useful life and/or can be economically repaired or upgraded. Green Space - planned and preserved open land; an interconnected system of open land, determined to have cultural, ecological, developmental, agricultural, and/or recreational value. Maximum Extent Practicable (MEP) — the technology-based discharge standard for Municipal Separate Storm Sewer Systems to reduce pollutants in storm water discharges that was established by CWA §402 (p). A discussion of MEP as it applies to regulated small MS4s is found at 40 CFR 122.34. MCMs means: Minimum Control Measures. The six MCMs are: Public education and outreach; Public participation/involvement; Illicit discharge, detection and elimination; Construction site runoff control; Post-construction site runoff control; and Pollution prevention/good housekeeping. Municipal Industrial Facility means: An industrial facility, as defined in the federal and state storm water regulations, which is owned or operated by a municipality. The regulations define covered industrial facilities by their Standard Industrial Classification (SIC) codes as published by the U.S. Office of Management and Budget. From this extensive list of covered SIC codes, the following operations have been identified as those most likely to be owned or operated by a municipality: Transportation Operations, Landfills, Hazardous Waste Treatment/Storage/Disposal facilities, Vehicle Maintenance or Fueling facilities, Vehicle Washing facilities, Solid Waste Transfer facilities, Wastewater Treatment facilities, Recycling facilities, Yard Waste/Composting facilities and certain types of Warehousing & Storage facilities. Municipal Separate Storm Sewer System (MS4) means: A conveyance or system of conveyances including roads and highways with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, paved or unpaved channels or storm drains designated and utilized for routing of storm water which is contained within the municipal corporate limits or is owned and operated by the state, city, town, village, county, district, association or other public body created by or pursuant to the laws of Missouri having jurisdiction over disposal of sewage, industrial waste, storm water or other liquid wastes and is not a part or portion of a combined sewer system. (This definition adapted from Section (1)(C)16 of Missouri Storm Water Regulation 10 CSR 20-6.200). Each of the 61 co-permittees operates its own MS4. In addition, the term is used to refer to the entire St. Louis County Plan Area which is identified in the Phase II permit as the St. Louis Metropolitan Small MS4. Municipal Work Group means: A group of municipal representatives organized under the provisions of Chapter 14 of the St. Louis County SWMP to develop a model Operation and Maintenance Program and a Training Program for the 61 co-permittees in order to comply with the provisions of Section 4.2.6.1.1 of the Plan Area Phase II storm water permit. The work group members are listed in Appendix 1-A3. 108 Municipality means: Any public entity as described in the definition of Municipal Separate Storm Sewer System. St. Louis County and the Metropolitan St. Louis Sewer District are considered "municipalities" for the purposes of the Phase II storm water permit along with the 59 cities, towns and villages who are co-permittees. The Missouri Department of Transportation (MoDOT) is also a "municipality" and operates an MS4 within the Plan Area. However, MoDOT is covered by a separate state permit and is not a co-permittee under the St. Louis Metropolitan Small MS4 permit. NPDES means: National Pollutant Discharge Elimination System. This term was introduced in Section 402 of the federal Water Pollution Control Act of 1972 (last amended in 1987 and now known as the Clean Water Act). Section 402 provides for the issuance of NPDES permits for the discharge of pollutants to waters of the United States and specifies the conditions under which permits may be issued. The 1987 amendments established the phased permitting requirements for municipal storm water discharges. In Missouri, the Missouri Department of Natural Resources has been delegated the authority to issue NPDES permits. Phase I means: The first phase of the federal storm water regulations. These took effect December 17, 1990. Phase I regulations provide for storm water permitting for industrial facilities, for land disturbance sites 5 acres or greater in size and for MS4s having populations greater than 100,000 (medium and large MS4s). Industrial facilities operated by municipalities, regardless of size, are included under Phase I. See definition of"Municipal Industrial Facility." Phase II means: The second phase of the federal storm water regulations. These took effect February 7, 2000. Phase II regulations provide for storm water permitting for MS4s, in urbanized areas as defined by the Bureau of the Census, with populations below 100,000 (Small MS4s) and for land disturbance sites between 1 acre and 5 acres in size. Each of the individual municipal entities within the St. Louis County Plan Area has a population below 100,000 and is, therefore, a Small MS4 subject to Phase II requirements. Phase II Permit means: Storm water permit# MO-R040005 with effective date of March 10, 2003, issued by the Missouri Department of Natural Resources to the 61 St. Louis County co- permittees. This permit was issued pursuant to the provisions of Missouri Storm Water Regulation 10 CSR 20-6.200. Plan Area means: The portion of St. Louis County served by separate storm sewers and within the corporate boundaries of the Metropolitan St. Louis Sewer District. The Plan Area includes the 59 cities, towns and villages who are co-permittees as well as unincorporated St. Louis County. While there are a total of 77 municipalities in the Plan Area, 18 have populations of less than 1000 and are therefore, exempt from the Phase II permitting requirements, per Section (1)(C)22 of Missouri storm water regulation 10 CSR 20-6.200. The City of St. Louis and twelve county municipalities adjoining the City of St. Louis are served by combined sewers and are not part of the Plan Area. The Plan Area is identified in the Phase II permit as the St. Louis Metropolitan Small MS4. Plan Area Training Committee means: The Municipal Work Group defined above. 109 Recycling Facility means any co-permittee-owned or operated facility which collects, for recycling, common household recyclables such as paper, plastic, glass, cardboard, etc. or which collects and processes yard wastes for use as mulch or compost. St. Louis Municipalities Phase II Storm Water Planning Committee means: The group of 22 representatives from municipal governments, St. Louis County, MSD and various state and regional agencies which developed the Storm Water Management Plan for St. Louis County. Separate Storm Sewer means: A pipe, conduit, conveyance or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, manmade channels or storm drains) designed and intended to receive and convey storm water and which discharges to waters of the state and which is not part of a combined sewer system. Storm Water means: rainfall runoff, snow melt runoff and surface runoff and drainage. Storm Water Management Plan (SWMP) or Plan means: The Plan developed for the St. Louis County Plan Area by the St. Louis Municipalities Phase II Storm Water Planning Committee and approved by the Missouri Department of Natural Resources through the issuance of NPDES permit MO-R040005. Sustainable (green) Service - A service acquired from a supplier who has a green operational policy and whose internal practices promote sustainability. Threshold - the dollar value of contracts, above which a formal record is kept on file showing that environmental criteria were considered when requirements were defined. Urban Runoff means: Storm water and other runoff from streets, parking lots, rooftops, residential, commercial and industrial areas and any areas that have been rendered impervious through development activities. Such runoff becomes contaminated with fertilizers, pesticides, vehicle drippings and emissions, animal wastes, street litter, yard wastes, silt, chemical spills and other urban wastes. These contaminants are carried through the separate storm sewers and discharged into area streams where they degrade the water quality, harm aquatic life and other wildlife, reduce aesthetic and recreational values and make the waters unsafe for human use.

All co-permittees are required to implement an Operation and Maintenance Program to comply with their permit. The St. Louis County Phase II Storm Water Management Plan calls for co- permittees to adopt the program by the end of permit year three, March 9, 2006, and fully implement it by the end of permit year four, March 9, 2007.Under the permit, MSD, as coordinating authority, must annually report the status of each co-permittees' compliance with the milestones in the Plan. A model program was developed to assist co-permittees in complying with the permit Section 4.2.6, and to help foster uniform approaches to implementing the Operation and Maintenance (O&M) Program. Each co-permit tee must include in their program the applicable elements from the model program, based on the extent of their infrastructure, municipal facilities and services. In drafting the model program, the authors made an effort to be as comprehensive as possible in addressing municipal operations by including generic example text for a variety of municipal operations. However, a co-permit tee may add measures as it deems appropriate to meet its specific needs. Co-permittees are expected to edit the text in this model program to specifically apply it to their organization by including details, commitments, and policies specific to their organization. To assist in this editing process, this document contains instructions to the co-permit tee editors in A SMALL CAPITAL, ITALICIZED FONT LIKE THIS. THESE INSTRUCTIONS must be addressed in the document and removed from the text before finalizing your city's plan. For additional information on the Best Management Practices (BMPs), please contact members of the Work Group, in Appendix 1-A3, or refer to EPA Fact Sheets on the web at: http://cfpub.epa.gov/npdes/stormwater/menuofbmps/poll.cfm.
