LOUIS * MISSOURI 2019 Adopted September 3, 2019 Note From The Authors This document is a Model Operation and Maintenance Program template developed to meet the requirements in the St. Louis Metropolitan Small MS4 Stormwater Permit, Section 4.2.6. All co-permittees are required to implement an Operation and Maintenance Program to comply with their permit. Stormwater 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-permittee 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-permittee 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-permittee 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.

December 2018 Chapter 1 - Program Administration A. Introduction: The Missouri Department of Natural Resources (MDNR) issued Phase II Stormwater Permit MO -R040005 to the City of Bel -Ridge and other co-permittees in St. Louis County, effective March 10, 2003. The area served by the 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, MCM 6 section of the permit requires each co-permittee 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 Stormwater Management Plan (SWMP) for the St. Louis Metropolitan Small MS4 Stormwater is implemented under the Phase II permit. As a co-permittee under the state permit the City of Bel -Ridge is bound by the commitments contained in the SWMP. The SWMP requires a model operation and maintenance program template and that each co- permittee implement a written operation and maintenance program. This document represents the City of Bel -Ridge implementation of the model operation and maintenance program as applicable and tailored to specifically meet City of Bel -Ridge needs and goals. This program impacts all facets of municipal operations. It is the City of Bel - Ridge 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 Bel -Ridge 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. B. Policies: The City of Bel -Ridge 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-B1. C. Organization of Manual: The SWMP prepared for St. Louis County by the Planning Committee contains a detailed 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-permittee may have activities in only some or in Page 4 of 31 Rev. December 2018 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 City of Bel -Ridge is not engaged in the subject activity. D. Administration: 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 Bel -Ridge will train all staff associated with activities that can impact pollution in stormwater runoff. Each chapter will identify employees who should be subject to training on that particular chapter. Employees will receive general stormwater 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 stormwater BMPs, proper waste management and 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 City of Bel -Ridge 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. Chapter 2 - General Housekeeping, Operation and Maintenance A. Description of Activities: Municipal operations include a variety of activities conducted to maintain City of Bel - Ridge 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.

Best Management Practices (BMP): FACILITIES • City uses recyclable materials whenever possible. o City uses non -hazardous fluorescent light bulbs. ® Avoid using copper or silver -containing algaecides in lake. ® Maintain site plumbing plans showing sanitary and storm sewer connections. Ensure wastewater is discharged only to the sanitary sewer, and stormwater to the storm sewer. Label storm drain inlets to ensure they are used only for stormwater drainage. MATERIAL MANAGEMENT • Collect and recycle, to the Kediice • then Recycle maximum extent practicable, wastes generated by municipal operations. (See the policy in Appendix 2-F1.) ® 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. ® Outdoor material stockpiles at both permanent locations and at job sites should be covered to protect from rainfall and prevent contamination of stormwater runoff. ® Material stockpiles which cannot feasibly be covered should be surrounded by a berm, sock or otherwise contained so that stormwater runoff can be captured. Page 8 of 31 Rev. December 2018 ® Petroleum products, fuels, chemicals, hazardous and toxic materials, and all wastes should be stored and handled with appropriate safeguards to prevent contamination of stormwater 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 clean-up 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. • 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. Page 9 of 31 Rev. December2018 COMMUNITY ® Develop/enforce ordinances for waste containers which regulate size, type, covers and water -tightness for residential, commercial and industrial areas. ® Develop/enforce ordinances against illegal dumping, littering and improper yard waste disposal, providing for corrective action, enforcement and penalties. ® Develop/enforce ordinances requiring pet owners, property owners, and equestrian and animal boarding facilities to clean up wastes from their pets and other animals. ® 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. ® 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 stormwater from sources such as failing septic tanks, septic tanks discharging to stormwater, 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. 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. F. NPDES Permit status: MDNR general storm water permits are not applicable — no city activities. G. Training: All employees involved in maintenance operations, construction, purchasing, facility or site design, or building or facility management will be trained on this chapter, including the following Departments and work units: In addition to training on the housekeeping BMPs and proper waste management, employees will be provided general awareness of NPDES discharge requirements. Page 10 of 31 Rev. December 2018 Chapter 3 o Vehicle/Equipment Repair and Maintenance Operations A.

Best Management Practices (BMP): OPERATIONS ® Institute a preventive maintenance program to minimize fluid leaks and equipment failures. Inspect vehicles and equipment frequently for leaks, collecting leaks with pans or absorbent, and repairing leaks. ® All routine vehicle maintenance and repairs at (municipality) 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. ® Environmentally safe detergents are used instead of caustic cleaning solutions. ® Flammable liquids are kept in a vented fire -rated cabinet. ® All supply material and waste containers are marked clearly and properly to identify the contents. ® Keep material safety data sheets (MSDS) for chemicals onsite for information on reportable spill quantities, proper handling and health and safety. Page 12 of 31 Rev. December 2018 " All supply material and waste containers are stored under cover to prevent contact with rainfall; or when uncovered, containers are clean and sealed. " Tops of containers have absorbent mats and are free of standing liquid, and stored containers are kept closed. � Waste oils, filters, antifreeze, and other wastes are collected in designated, labeled containers and recycled to the maximum extent practicable. � Wheel weights are kept in a container marked _' "scrap lead". ^P -,'L � 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. � 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. 9 Batteries, waste oil, etc. having spill/leak potential are stored indoors and are in secondary containment, when possible. � Neutralizer and absorbent are kept by both new and used batteries. � All floors are clean of oil and grease. O 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. O 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. � Procedures for loading, unloading and transfer operations should be developed to prevent overfilling and spills. O 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. Page 13 of 31 Rev. December 2018 " Maintain equipment to ensure the proper operation of automatic shutoff devices on pumps and, overfill protection and spill buckets on tanks. " Emergency phone numbers are clearly posted in the shop and near material storage areas. FACILITY " All floors in work areas are sloped to floor drains that are connected to an MSD- approved sediment /oil trap prior to discharge into the sanitary sewer system. Trap is pumped out quarterly, or as needed. " A site -plumbing schematic showing all drains, traps, and shut offs for utilities should be posted in shop. Employees should be made aware of sanitary and storm sewers to ensure all wastewater is discharged to the sanitary sewer. " 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 stormwater. The area should be graded and sloped to direct stormwater runoff away from the site and to prevent runoff from flowing over the fueling area. " Stormwater 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. F. NPDES (National Pollutant Discharge Elimination System) Permit status: Vehicle maintenance facilities of this type are considered "municipal industrial" facilities under the Missouri Stormwater Regulations and are subject to separate NPDES stormwater (Phase I) permitting requirements under MDNR general permit R80C. As stated above, all of City of Bel -Ridge vehicle repairs and maintenance are preformed indoors or are otherwise done without exposure to stormwater. Therefore, a NPDES Stormwater permit is not required and a no -exposure certification has been filed with the Missouri Department of Natural Resources. H. Training: Training on stormwater BMPs will be provided to mechanics, storekeepers, material handlers, laborers, equipment operators, janitors, and management staff working at facilities identified in Section B. All employees will be provided safety training and training on written procedures pertaining to general housekeeping. Implement monthly safety meetings to include environmental training and HAZMAT training. Chapter 4 - Vehicle/Equipment Washing A. Description of Activities: The City of Bel -Ridge does not wash vehicles at its facilities. Vehicles are taken off -site for washing. Page 14 of 31 Rev. December 2018 Chapter 5 - Facility Repair, Remodeling and Construction A. Description of Activities: On an as -needed basis, City personnel perform minor renovations/repairs and small capital improvements on City facilities, such as erecting or removing partitions, replacing a door or window, painting, etc. Major projects are typically contracted out to commercial firms specializing in the type of work required. Chapter 6 - Cleaning and Maintenance of Roadways, Highways, Bridges and Parking Facilities A. Description of Activities: The City of Bel -Ridge performs the cleaning and maintenance of roadways, highways, and parking facilities under their maintenance purview. Activities include, but may not be limited to trash pickup from gutters & sewer inlets, patching, snow removal, and emergency situations involving spills and accidents. Trash pickup from gutters & sewer inlets are performed on a scheduled basis, or when requested, and is usually conducted on roads with curbs where debris can accumulate in the gutter line. Patching operations involve the preparation of potholes and the fill of either hot mix or cold patching material. 1. Preparation — Cut hole out with straight edges at 90 degree angles. Remove loose asphalt and debris. Line edges with emulations and fill. 2. Filling & Finishing — April to October months, hot patch is used to fill asphalt holes, November to March months, cold patch is used to fill asphalt holes. Both patches are then either rolled or power tamped. The City of Bel -Ridge plow and salt the roadways under their maintenance jurisdiction during winter snow events. Typically, 16 tons of salt is used to de-ice the pavement per snow event. The City of Bel -Ridge will contact the corresponding fire department 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 structures of the City of St. Louis, Saint Louis County, and all municipalities within the boundaries of Saint Louis County. Page 15 of 31 Rev.
