INTRODUCTION: The Missouri Department of Natural Resources (MDNR) issued Phase II Storm Water Permit MO -R040005 to the City of Oakland 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-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 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- permittee under the state permit, the City of Oakland 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 Oakland's adoption of the work group's model program as applicable and tailored to specifically meet the City of Oakland's needs and goals. This program impacts all facets of municipal operations. It is the City of Oakland's 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 Oakland 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 No. 2007-02 on May 14th, 2007 (See Appendix 1- A4). B. POLICIES: Not Applicable. 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 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 Oakland is not engaged in the subject activity. D. ADMINISTRATION: The responsible party for administration of the Operation & Maintenance (O&M) Program is the City Administrator/City Clerk . 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 Oakland 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, when required and appropriate. Upon implementation of specific procedures, management will review the new procedures that incorporate storm water 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, when required and appropriate. 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 when required. To maintain proficiency, a schedule of periodic retraining will be implemented or provisions will be 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 (when required) will be maintained.

DESCRIPTION OF ACTIVITIES: Municipal operations include a variety of activities conducted to maintain City leased 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: NA- The City of Oakland does not have a City Hall or any other municipal facilities. City Hall staff consists of one full-time employee and two part-time employees who each work from their respective homes. C. RESPONSIBLE PARTIES: The City Administrator/City Clerk has authority over City contractors. o City Administrator/City Clerk: (314) 416-0026 D. MATERIALS/SUPPLIES ACQUISITION, STORAGE AND USAGE: NA F. BEST MANAGEMENT PRACTICES (BMP): Facilities: • 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 non -chemical 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. • 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.)

DESCRIPTION OF ACTIVITIES: On an as -needed basis, repairs and maintenance are contracted out to commercial firms specializing in the type of work required. B. LOCATIONS: City Parks C. RESPONSIBLE PARTIES: The City Administrator/City Clerk is the responsible party that will ensure all repairs or construction will be preformed without subjecting the storm water system to any new contaminant streams. He/she is responsible for monitoring the construction practices of the contractors that work for them at these sites. D. MATERIALS/SUPPLIES ACQUISITION, STORAGE AND USAGE: The contractor hired by the City is responsible for purchasing and storing materials on an as needed basis and in quantities expected to be completely consumed in the process of completing the project. Materials used for every project will vary. The majority of materials are purchased on a project basis and are consumed during that project. Materials should be stored indoors or under cover so they are protected from rainfall and runoff. All unused portions of materials should be properly secured to prevent loss. Tarps should be used on the ground to collect fallen debris and other spilled material. Waste should be cleaned up on a daily basis and properly disposed of as noted below in section "E". E. WASTE GENERATION, STORAGE, DISPOSAL, RECYCLING: Waste generation varies with the nature of the job. Typically, wastes consist of small amounts of lumber cut-offs, wallboard scraps, empty paint cans, etc. Order and mix only the amount of materials necessary for the work to be completed. Dispose of all waste properly, recycle whenever possible. Never bury waste material or leave material in the street, gutter, or near a creek or streambed that would allow the material to enter the storm water system. It is the contractor's responsibility to dispose of such materials in accordance with requirements defined herein, per the City's Solid Waste Code, and as defined in the contract and/or agreement. Leaks, drips, or spills should be cleaned up immediately. Clean up using "dry" methods, absorbent materials or rags, or remove the contaminated soil or material. Clean up of equipment is to be performed in designated areas. Never clean up concrete equipment or paintbrushes and allow the washout into the street, storm drains, drainage ditches, or streams. Page of 86 CITY OF OAKLAND - OPERATION AND MAINTENANCE PROD 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/owowwtr1/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, Regulations, and Engineering Design Requirements for Sanitary Sewage and Stormwater 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 • Carefully design and install plumbing and storm water systems to code, eliminating cross - connections between sanitary and storm drain systems. • 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 • All construction or maintenance activities that excavate in, 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 -Fl for a summary of permit requirements. Construction/Remolding: • 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 of by the City contractor. CITY OF OAKLAND - OPERATION AND MAINTENANCE PROGRAM Page of $5 " Keep work sites clean, pickup trash that can be wind blown daily. " Utilize certified asbestos inspectors to inspect floor tile, ceiling tile, fireproof 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. NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (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: Not Applicable. Page of 86 CITY OF OAKLAND - OPERATION AND MAINTENANCE PROG11A41 CRY OF OAKLAND - OPERATION AND MAINTENANCE PROGRAM Page of S6 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 structures of the City of St. Louis, Saint Louis County, and all municipalities within the boundaries of Saint Louis County. The City of Oakland is responsible for maintaining all public streets within the City of Oakland. The responsibilities include but are not limited to street cleaning, street striping, pot hole repair, asphalt overlay and street replacement when necessary. Page of 86 CITY OF OAKLAND - OPERATION AND MAINTENANCE PROOF C. RESPONSIBLE PARTIES: The responsible party involved in the cleaning and maintenance of streets is the City Administrator/City Clerk. D. MATERIALS/SUPPLIES ACQUISITION, STORAGE AND USAGE: All materials are purchased and used immediately. 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 by the City Contractor. Waste Maximum Storage Capacity Storage Location Method Of Disposal Frequency Asphalt Millings from Co- Planning Operation Stored by City Contractor Landfill or Other Locations First preference is to recycle the material, using it for road base, parts, earth fill (if laws permit), or in asphaltic concrete, etc. If material cannot be economically recycled, it will be disposed of in a landfill. As Generated Concrete Rubble Stored by City Contractor Earth Fill or Landfill First preference is to place concrete waste in earth fill; however, if this cannot be economically accomplished, the spoil material is taken to a landfill. As Generated Trash, Grit and Debris from Street Sweeping and Road Clean Up Sanitary Landfill As Generated Water Based Paint Sanitary Sewer, as Approved by MSD. As Generated CITY OF OAKLAND - OPERATION AND MAINTENANCE PROGRAM Page of $6 F. BEST MANAGEMENT PRACTICES (BMP): 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. • Used asphalt is recycled when it is cost -beneficial. • Block scuppers and drains when sealing bridge decks. • 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: bridgework, culverts under road crossings, dredging or placing riprap in creeks. See Appendix 5-F1 for a summary of permit requirements. De -Icing: • Use calibrated/controlled chemical applicators for salt and brine applications. • Minimize the use of salt without compromising public safety. • Stop salt feed on trucks at stop signs, where equipped. • 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, brooming, etc.) prior to roadway flushing on bridges. • 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. • 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. • Do not hose down parking lots in a manner that discharges wash water to the storm drain untreated.

RESPONSIBLE PARTIES: Not Applicable D. MATERIALS/SUPPLIES ACQUISITION, STORAGE AND USAGE: Not Applicable E. WASTE GENERATION, STORAGE, DISPOSAL, RECYCLING: Not Applicable F. BEST MANAGEMENT PRACTICES (BMP): Park Design and Sitting: • 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. • 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 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 Page of 86 CITY OF OAKLAND - OPERATION AND MAINTENANCE PROGN 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 Stormwater 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. • 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. • Control wild geese populations near lakes with "no feeding the geese" signs and ordinances. Other techniques to control populations include habitat modification by increasing shoreline vegetation height, scare tactics or relocation. 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. • 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 methylene urea, IDBU or resin coated fertilizer. • 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 CITY OF OAKLAND - OPERATION AND MAINTENANCE PROGRAM Page of 86 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/agguides/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. • Apply pesticides when the target pest is at its most vulnerable life stage, and use site specific rather than wholesale application. • 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.

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 Stormwater 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 Stormwater Drainage Facilities".

BEST MANAGEMENT PRACTICES (BMP) • General: • 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 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. Catch Basins: • 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: • 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. • Utilize care in cleaning storm sewers by flushing, to properly collect waste using debris/sediment traps.

" Minimize or avoid the use of chemical root/vegetation killers, and use the least toxic alternatives when necessary. Drainage Channels: " 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 simply moving problems downstream. Re -vegetate 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: " 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".

The permittee shall describe Page of 86 CITY OF OAKLAND - OPERATION AND MAINTENANCE PR003441 how this training program will be coordinated with the outreach programs developed for the public information minimum measure and the illicit discharge minimum measure. 4.2.6.2.3 The permittee' s program description shall specifically address the following areas: 4.2.6.2.3.1 Maintenance activities, maintenance schedules, and long term inspection procedures for controls to reduce floatables and other pollutants to the permittee's regulated small MS4. 4.2.6.2.3.2 Controls for reducing or eliminating the discharge of pollutants from streets, roads, highways, municipal parking lots, maintenance and storage yards, waste transfer stations, fleet or maintenance shops with outdoor storage areas, and salt/sand storage locations and snow disposal areas the permittee operates. 4.2.6.2.3.3 Procedures for the proper disposal of waste removed from the permittee's MS4 and area of jurisdiction, including dredged material, accumulated sediments, floatables, and other debris. 4.2.6.2.3.4 Procedures to ensure that new flood management projects are assessed for impacts on water quality and existing projects are assessed for incorporation of additional water quality protection devices or practices. 4.2.6.2.4 Identification of the person(s) responsible for overall management and implementation of their pollution prevention/good housekeeping program and if different, the person responsible for each of the BMPs identified for this program. 4.2.6.2.5 How the permittee will evaluate the success of this minimum measure, including how the permittee selected the measurable goals for each of the BMPs. 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, Compensation, and CITY OF OAKLAND - OPERATION AND MAINTENANCE PROGRAM Page of 86 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.

SECTION TWO: That the City Administrator is hereby directed to keep the plan up to date as required by the Plan. SECTION THREE: That this Resolution is immediately accepted upon its passage and approval. This Resolution Passed and Approved this 14th day of May, 2007. Paul Marti Mayor ATTEST: Kathleen Yahl City Administrator/Clerk Page of 86 CITY OF OAKLAND - OPERATION AND MAINTENANCE PROG449 APPENDIX 2-F1 THE CITY OF OAKLAND WASTE REDUCTION AND RECYCLING POLICY STATEMENT POLICY The City of Oakland is committed to good stewardship of the environment. A key element of that stewardship is the reduction of the amount of solid waste going from the City into landfills. Solid waste landfills have negative long-range environmental impacts, drain community resources, and have limited capacity to accept the large quantities of waste generated by our society today. The City of Oakland will make every effort to reduce the solid waste generated at our facilities. Four methods will be used to implement this policy: source reduction, reuse of materials, recycling, and purchase of recycled materials when practical and cost effective. Every City employee has a personal responsibility for implementing this policy. METHODS TO ACHIEVE SOLID WASTE REDUCTION • Source Reduction: All members of the City staff are responsible for implementing operational practices that prevent waste from being produced, when practical and where such practices will not compromise the mission or end product. Examples include printing reports and documents on both sides of the paper; printing appropriate numbers of documents; using email rather than printed correspondence; and using products that are reusable, refillable, repairable, non-toxic, recyclable. Products with reusable, returnable packaging or items requiring the least possible packaging should be purchased when practical. Every effort should be made to prevent excess or unneeded materials from being purchased. • Reuse of Materials: All employees of the City are responsible for reusing products whenever possible. An example would be to use dishes, glasses, and reusable flatware rather than disposable paper and plastic ware. • Recycling: All City employees are responsible for separating identified recyclable materials and placing them in appropriate recycling containers. City Recycling includes, cardboard, hard back books, newspapers, phone books, catalogs and magazines, brown paper bags, news blend, office blend,) toner cartridges, and additional items as implemented. . • Purchase of Recycled Content Material: The City Administrator/City Clerk is responsible for making efforts to purchase and use products manufactured from or containing recycled materials. PROCEDURES The City Administrator/City Clerk will be responsible for implementing this policy. CITY OF OAKLAND - OPERATION AND MAINTENANCE PROGRAM Page of 8tb APPENDIX 2-F2 THE CITY OF OAKLAND GREEN PROCUREMENT POLICY POLICY OBJECTIVE: The objective of this policy is to provide direction for greening City of Oakland procurement. POLICY STATEMENT: As set out in this Policy, priority in procurement will be given to green products and services, including construction. DEFINITIONS: • Green Procurement — is 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. This comparison may consider raw material acquisition, production, manufacturing, packaging, distribution, operation, maintenance, disposal and re -use of the product or service. Green procurement encompasses the concept of the procurement of goods and services that provide for basic human needs and bring a better quality of life, while minimizing the use of non-renewable natural resources and toxic materials and the emission of wastes and pollutants over the life cycle, so as not to jeopardize the ability of future generations to meet their own needs. • Green Product — is one that is less harmful than the alternative, having characteristics including, but not limited to, the following: o Recyclable - local facilities exist that are capable of recycling the product at the end of its useful life. o Biodegradable - will not take a long time to decompose in landfill. o Contain recycled material (post -consumer recycled content). o Minimal packaging and/or for which there will be take -back by the manufacturer/supplier of packaging. o Reusable or contain reusable parts. o Minimal content and use of toxic substances in production. o Produce fewer and/or less polluting by-products during manufacture, distribution, use and/or disposal. o Produce the minimal amount of toxic substances during use or at disposal. o Make efficient use of resources - a product that uses energy, fuel or water more efficiently or that uses less paper, ink or other resources. o Durable - have a long economically useful life and/or can be economically repaired or upgraded. • Sustainable (green) Service - A service acquired from a supplier who has a green operational policy and whose internal practices promote sustainability. Page of 86 CITY OF OAKLAND- OPERATION AND MAINTENANCE PROD " 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. POLICY PROCEDURES: Where available and cost effective, green products and services, including construction, that are of equal or better performance and quality, will be purchased. In determining cost effectiveness, the City should give consideration to the costs and benefits that accrue, in the shorter and longer term, to the City of Oakland. For all bid solicitations (e.g. requests for proposal, requests for quote, and requests for standing), environmental factors or impact will be considered when requirements are defined. In addition, bid solicitations will include instructions asking bidders to identify any environmental benefits over the life cycle of their products and/or services. Green procurement principles will be applied to construction projects beginning with the design stage. Departments will determine the contract dollar value (hereafter referred to as the threshold) above which a formal record is kept on file showing that environmental criteria were considered when requirements were defined. In determining their threshold, departments may wish to consider contracting volumes, training requirements and budgetary constraints. For all procurement, consideration will be given to environmental factors or impact. For requirements: " Valued in excess of a threshold, a formal record of the evaluation will be kept on file. In the case where a green purchase was made, the record will list the environmental criteria included in the bid solicitation. In the case where a green product or service was not acquired, the reasons for not selecting an environmentally preferable product or service will be documented. See Documentation Form attached. " Valued at or below the threshold, a formal record of the evaluation is not required. Each department will be responsible for ensuring that its personnel have sufficient training about the environment and green procurement to carry out the directives in this policy. GUIDELINES " The life cycle approach and the environment o Applying the four R's (Reduce, Reuse, Recycle and Recover) at each phase of the material management life cycle helps protect the environment and reduce costs. " Planning o During the planning process, managers will assess the need for a given purchase and, whenever possible, CITY OF OAKLAND - OPERATION AND MAINTENANCE PROGRAM Page of 88 " Reduce consumption. " Consider acquiring second-hand or used material. " Consider products that are less damaging to the environment, such as those made with resource -saving materials or processes. " Consider the environmental cost of purchases during each phase of the life cycle. " Acquisition o As much as practical, products selected should: " Be reusable and contain reusable parts. �% Be recyclable and contain recycled materials (e.g. recycled paper, reconditioned laser printer cartridges). " Include second-hand or used material. " Use resources and energy efficiently. " Have a long service life or be economical to repair. �% Contain minimal packaging, or use returnable or reusable shipping containers. " Be non-toxic and non-polluting. " Maintenance and Operations o Ensure that products are properly maintained and used. This will extend the service life of a product. When economically feasible, equipment should be repaired, refinished and reused. o Hazardous material must be shipped, stored and handled in accordance with applicable federal and provincial law, and regulations. " Disposal o Consider alternatives to disposing of material, such as reusing, recycling or recovering it. Try to minimize the amount of waste generated. o Combine environmental actions with fiscal responsibility " Government interest in economy of operations is fully compatible with environmental interests. Many sound environmental practices have resulted in savings. �% Most environmental actions can be phased in gradually without additional cost. When these actions may entail additional costs for the government, managers should accommodate them within existing budgets. " Government should lead by example. In light of the volume of government procurement, the government can play a significant role in promoting the development and marketing of green products and services. As demand for these products and services increase their prices will drop and become more affordable to all consumers.

The permitting and certification process is shared between the Corps and the MDNR. If you are considering a project that may involve placing materials in a lake, river, stream, ditch or wetland (including dry streams, ditches or wetlands) contact the Corps to find out if the project you are planning is in jurisdictional waters and is a regulated activity. The Corps has the sole authority to determine whether the activity is regulated; whether a site specific, individual 404 permit is required, or whether a Nationwide Permit (NWP) applies for projects with minor impacts. If a NWP does apply, contacting the Corps of Engineers is recommended to determine thresholds for notification under the NWP, and to obtain additional regional requirements imposed by the Corps' St. Louis Office. The MDNR requires any project that needs a 404 Permit from the Corps (individual or NWP) to also obtain a 401 Water Quality Certification (401 Certification) from MDNR. The 401 Certification is verification by the state that the project will not violate water quality standards. The department may require actions on projects to protect water quality in the form of certification conditions. For some of the NWPs, the MDNR has published their conditions that must be met in addition to the NWP conditions. After you contact the Corps about your project and, if applicable, submit an application, they will send you a letter authorizing your project under a particular permit. If the Corp's letter to you indicates that you must obtain an individual 401 certification, you must send an application to MDNR also. If they state that MDNR has `conditionally certified' your activity, and have enclosed certification conditions, then nothing further is needed. Questions about permit applicability and procedures for obtaining individual permits can be found by calling the Corps of Engineers at 314-331-8575 or 314-331-8186. Permit application forms and procedures for applying to the Corps and the MDNR can be found on the following web pages: http://www.mvs.usace.army.mil/permits/permitap.htm. http://www.dnr.mo.gov/wpscd/wpcp/401/wpcp-401.htm#general. The following is a list of NWPs commonly applicable to municipal operations. For most of these NWPs, the MDNR has conditionally certified these activities. The NWPs will list numerous thresholds for applicability and notification in terms of linear feet and acreage of the project. • NWP 3 Maintenance — repair or replacement of an existing structure, and removal of accumulated sediment or placement of riprap to protect a structure. • NWP 7 Outfall Structures — construction of new outfall and intake structures, and removal of accumulated sediment blocking these structures. Page of 86 CITY OF OAKLAND - OPERATION AND MAINTENANCE PROOF " NWP 12 Utility Lines  construction, maintenance, and repair of utility lines (sewer, water, electric or communication), including outfalls and excavations for the utility line. " NWP 13 Bank Stabilization  stabilization projects for erosion protection. " NWP 14 Linear Transportation  construction or modification of linear transportation crossings, such as bridges and culverts for roads and trails. " NWP 27 Stream and Wetland Restoration Activities  activities associated with the restoration of former waters, or the enhancement or creation of wetlands and riparian areas, or the restoration and enhancement of streams, including activities associated with flow modification, habitat and vegetation. " NWP 31 Maintenance of Existing Flood Control Facilities  dredge or fill activities associated with maintaining existing flood control facilities such as retention/detention basins and channels. " NWP 41 Reshaping Existing Drainage Ditches  dredge or fill activities to modify the cross- sectional configuration of drainage ditches, not modifying capacity beyond the original design. " NWP 43 Storm Water Management  construction, maintenance, and dredging of storm water management facilities, such as ponds, detention/retention basins, outfalls, and emergency spillways.

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  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)  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  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. CITY OF OAKLAND - OPERATION AND MAINTENANCE PROGRAM Page of 86 Municipality — 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 — 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 — 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 — 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 — 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 — 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 — The Municipal Work Group defined above. Page of 86 CIT Y OF OAKLAND - OPERATION AND MAINTENANCE PROOH Recycling Facility — 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 — 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 — 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 — Rainfall runoff, snow melt runoff and surface runoff and drainage. Storm Water Management Plan (SWMP) or Plan — 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 — 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.
