HomeMy Public PortalAboutCity of Rock Hilla guR THEPREVENTIO ay0 MINTHEC Note From The Authors This document is a Model Operation and Maintenance Program developed to meet the requirements in the St. Louis Metropolitan Small MS4 Storm Water Permit, Section 4.2,6. 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-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 ais 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. 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. Page 3 of 91Rev. 2/18/05 Chapter 1 , Program Administration A. Introduction: The Missouri Department of Natural Resources (MDNR) issued Phase 11 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-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 (municipality name) 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 Rock Hill adoption of the work group's model program as applicable and tailored to specifically meet Rock Hill needs and goals. This program impacts all facets of municipal operations. It is the city of Rock Hill 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 (city) 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. 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 Page 7 of 91 Rev. 2/18I05 addressed in the following Chapters 2 through 10. A statement of non -applicability is contained in those chapters where the city of Rock Hill is not engaged in the subject activity. 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 Rock Hill 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 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. Page 8 of 91Rcv.2/18ro5 Chapter 2 - General Housekeeping, Operation and Maintenance A.

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. Page 13 of 91xtv.2/18/05 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, aerification, and thatch control. Refer to MU Extension Publication IPM1009: http://muextension.missouri.edu/xplor/agguides/pests/ipm1009.htm (See Chapter 7 for additional BMPs.) MATERIAL MANAGEMENT Develop.a policy to purchase Redrice %.!. then Recycl recycled products or products with high post -consumer waste content whenever practical. Many resources are available from the EPA WasteWise Helpline: 800 EPA -WISE. Website: http://www.epa.gov/epaoswer/non- hw/reduce/wstewise/wrr/buyq&a. htrn 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://yosernite1.epa.gov/oppt/eppstand2.nsf/ See Appendix 2-F2 for a sample green procurement policy or http://www. pwq sc.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. Outdoor material stockpiles at both permanent, locations and at job sites should be covered to protect from rainfall and prevent contamination of storm water runoff. Material stockpiles which can not feasibly be covered should be surrounded by a berm or otherwise contained so that storm water runoff can be captured. Petroleum products, fuels, chemicals, hazardous and toxic materials, and all wastes should be properly labeled to ensure appropriate handling and disposal. Petroleum products, fuels, chemicals, hazardous and toxic materials, and all wastes should be stored and handled with appropriate Page 14 of 91 Rev. vi B/os 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 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. 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. 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 Develop/enforce ordinances for waste containers which regulate size, type, covers and water -tightness for residential, commercial and industrial areas. (See Appendix 2- F3 for language from the St. Louis County Waste Management Code.) Page 15 of 91 Rev. 2/18/05 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. 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: htto://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: Applicable MDNR general storm water permits must be obtained if the (city) engages in the following activities described by the following categories: . Airports (R80F) — Storm water runoff from airports that use de-icers or conduct uncovered vehicle or aircraft maintenance, washing, or fueling. 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-minimis exemption under certain conditions. Page 16. of 91 Rev. VI8/05 Recycling facilities (R80H, 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. Swimming pools (G76) — Discharges of filter backwash and pool drainage from swimming pools and lined ponds. Transportation Operations (local bus, etc.) — requires a site specific storm water permit. Trucking (R80C) - Motor freight transportation (garbage, refuse, etc.). Vehicle Maintenance (R80C, See also Chapter 3) - Motor freight transportation and warehousing. Warehousing and storage (R80C) - Motor freight transportation and warehousing. If the above categories describe (city) operations, but the activities and materials stored or handled are not exposed to storm water, a "No Exposure Certification" must be submitted in lieu of obtaining a permit. Further descriptions and a copy of the general permits are available at: www.dnr.mo.gov/wpscd/wpcp/permits/wpcpermits-qeneral.htm The discharge of process waste water to a storm water inlet from any (city) facility requires an NPDES Operating Permit from MDNR's Water Pollution Control Program. All permit conditions and limitations must be complied with. H. Traininq: 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: Vehicle maintenance department — mechanics, storekeepers and management. Public works department — equipment operators, laborers, and management. In addition to training on the housekeeping BMPs and proper waste management, employees will be provided general awareness of NPDES discharge requirements. Page 17 of 91 Rev. 2118/05 Chapter 3 - Vehicle/Equipment Repair and Maintenance Operations A. Description of Activities: Most vehicle maintenance and repairs are contracted with the city of Kirkwood fleet maintenance. Outside contractors perform services such as glass repair or replacement and all bodywork. B. Locations: The main garage located at 930 Des Peres Avenue. It is responsible for approximately 10 pieces of equipment. This location has one welding area and five work bays. None of the work bays have above ground lifts. The materials/ supplies used at this facility are all stored inside. These facilities are responsible for 10 pieces of equipment combined. The floor drains at districts 3,4, and 5 are connected to sediment/ oil traps. The bulk oils and fluids that are used at the districts are stored inside in a designated area. All bottled oils and spray chemicals are stored inside in the storage room. The majority of repairs of vehicle maintenance is done at the fleet maintenance operations in Kirkwood. C. Responsible Parties: The public works director oversees -all vehicle maintenance. D. Materials/Supplies acquisition, storage and usage: Materials /supplies for all locations are ordered through the main garage and delivered directly to each location. The following materials and quantities are typically kept on hand for main garage operation: Page 18 of 91 Rev. 2/ 18/05 The following aterials and quantities are typically kept on hand for each work location: Material MaximumOnHu n ity Kept For Use Within Stora e Location VARIOUS MOTOR OILS 50 quarts 6 months Locked storage room E.

Inspect vehicles and equipment frequently for leaks, collecting leaks with pans or absorbent, and repairing leaks. Ali 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. 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". 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. 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. 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. Always use drip pans Page 20 of 91xev. vis/os 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. 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. 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 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. 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. Page 21 of 91 Rev. vi Rios G.. NPDES (National Pollutant Discharge Elimination System) Permit status: 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. H. Training: Training on storm water 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 Description of Activities: Municipality) will wash vehicles and equipment at wash bay facilities designed according to this chapter. At (municipality) facilities where no wash bay exists, all vehicles and equipment will be taken to commercial facilities when washing is required. B. Locations: The (municipality) wash bay facili#ies are located at the following locations: 1) 930 Des Peres C. Responsible Parties: The Facility Superintendent responsible for pool vehicles, Ron Meyer, is responsible for ensuring that vehicles are taken off -site to approved commercial facilities for washing, or that washing on (municipality) property is done in the locations specified in Section B. D. Materials/Supplies acquisition, storage and usage: The wash soap to be used is Salt -Away. E. Wash bay design and waste disposal: Page 22 of 91 Revv t a/os Wash water from vehicle and equipment washing must be disposed in the MSD sanitary sewer, with pretreatment using a sediment/oil trap. The accumulated solids in the sediment/oil trap must be pumped out and properly disposed of, such as at a wastewater treatment plant by an MSD approved waste hauler. If floating oils and grease accumulate in the sediment/oil trap, the contents must be disposed by a permitted waste hauler at a commercial facility able to handle oily waste. F. Best Management Practices (BMPs): All vehicles are taken to commercial facilities when washing is needed. Commercial facilities used are verified to be in compliance with MSD sewer discharge requirements. Facilities must discharge wastewater to the sanitary sewer system, and wash bays must be covered to prevent storm water in the sanitary system. Wash bay facilities are designed to collect wash water, pretreat with a sediment/oil trap interceptor), and discharge to the sanitary sewer system. The trap must be pumped quarterly, or as needed. Wash bays are covered and wash area curbed or otherwise drained to prevent storm water runoff from discharging to the sanitary system. Uncovered wash bays have an inlet valve to the sanitary sewer. The wash bay is cleaned and the valve is maintained closed when washing is not occurring, to keep uncontaminated storm water out of the sanitary sewer. Post instructions regarding the use of the valve. Mobile wash services must collect wash water for recycling or proper disposal into a sanitary sewer. Job -site mud removal is performed without detergent in a contained, permeable (gravel) area with wash water infiltrating into soil or gravel. G. NPDES Permit status: Not applicable. H. Training: Employees responsible for operating fleet vehicles and equipment will be made aware of BMPs regarding washing, and the proper, designated locations for washing. Page 23 of 91 Rev. VI8/05 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. B. Locations: City hall and central garage contain a shop and material storage areas for facility repair, remodeling and construction; and city employees are involved in these activities. Repair, remodeling, construction and capital improvements are periodically performed on all types of municipal facilities. C. Responsible Parties: Facilities Manager — The Facilities Manager or Facilities Supervisor is the responsible party that will ensure all repairs, remodeling and construction will be preformed without subjecting the storm water system to any new contaminant streams. They are responsible for the construction practices of the contractors that work for them on municipal facilities. D. Materials/Supplies acquisition, storage and usage: Varies with nature of job. Materials are purchased 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, such as bagged cement. 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 uE". Routinely stocked materials are identified in the following table. Material Maximum Quantity Kept onsite Storage Location Lumber 100 Linear Feet Shop area Drywall NIA r Dirt 50 Tons Yard Rock 50 Tons Yard Oil -Based Paint 15 Gallons Locked storage area Page 24 of 9 t Rev. 2/18/05 Latex Paint 50 Gallons Waste generation, storage, disposal, recycling: Locked storage area Waste generation varies with the nature of the job. Typically, wastes consist of small amounts of lumber cutoffs, 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. Such materials are disposed in the city hall dumpster for pick-up by the city contracted waste hauler. Listed below are the disposal methods for various types of materials that are generated from facility repairs and remodeling: Waste Storage Requirements Method Of Disposal Contractor Lumber, Drywall, Siding, Roof Shingles, Insulation Dumpster or Container Sanitary or Demolition Landfill Waste Vendor Fluorescent, Sodium Vapor, Mercury Vapor Lamps Closed, Labeled Container Recycling as Universal.

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): Page 25 of 91 Rev. 2/I8/05 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 and 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.stormwatercenternet 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 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. 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. Page 26 of 91 Rev. 2/18/05 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 durnpster. if larger quantities are generated, arrangements are made with a city - contracted hauler for a special pick-up. Keep work sites clean, pickup trash that can be wind blown 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 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 workplace safety and provide a positive public image. Page 27 of 91 Rev. 2118/05 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 riormally 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 400pounds 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 public streets with the exception of start highways and county roads. C. Responsible Parties: Page 28 of 91 Rev, 2/18/05 Public Works Director — (314) 561-4316 Public Works Foreman- (314) 561-4316 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 immed ate and long- range needs for such materials, and adjust their purchasing habits accordingly.

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. Page 29 of 91 Rev. 2/18/05 Waste Maximum Storage Capacity Storage Location Method Of Disposal Frequency Asphalt Millings from Co -Planing Operation Unlimited Storage Options 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 can't be economically recycled, it will be disposed of in a landfill. Twice a year Concrete Rubble Unlimited Storage Options 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.

Store <90 Days 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 slate certified removal contractors for lead based paint abatement. Page 30 of 91 Rev. 2/18/05 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: 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 Use calibrated 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.) prio 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. 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. Do not hose down parking lots in a manner that discharges wash water to the storm drain untreated. Page 31 of 91 Rev. 2/18/05 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. Chapter 7 - Maintenance of Parks, Green Spaces, Trails and Landscaping A. Description of Activities: The city of Rock Hill has 6 parks totaling approximately 15 acres of land, and over 1 mile of hiking trails. The city of Rock Hill has responsibility for the development and maintenance of recreational areas and green space within the city, including neighborhood and walking paths, trees, public facility landscaping and public street right-of-way landscaping. 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 the walking trail), routine cleaning of park restrooms, and parking lot maintenance. B. Locations: Hensley Park is located between N. Berry Road and Salem Hills Drive Whitfield Park is located at 1348 N. Berry Road Turner Park is located at 229 Eldridge Stroup Field is located at 9650 Old Warson Road Oakhaven Park is located at 9930 0 khaven Avenue Oak Trail is located at 9955 Oakhaven Avenue Green spaces are interlaced throughout the community and are maintained by the. Public Works Department. C. Responsible Parties: Page 32 of 91 Rcv. 2/18ro5 The Director of Public Works has authority over all parks maintenance. Parks are actively managed by the Director of Parks and Recreation and the Public Works Director. D. Materials/Supplies acquisition, storage and usage: The following materials and quantities are typically kept on hand for landscaping and park maintenance operations. Material Maximum Quantity Kept On Hand For Use Within Storage Location Comments Mulch Pile 50 yards 6 Months Dirt area Fertilizer Purchased as needed Herbicide Purchases as needed Rock NIA Waste generation, storage, disposal, recycling: Wastes' generated by landscaping and park maintenance operations are as follows.

Tree buffers and tall grass filters around streams im •rove wate slow runoff and prevent erosion. A minimum buffer Avoid site development and placing facilities in the Design park sites to preserve natural resources suc draining areas, minimizing their loss and maintaining Page 33 of 91Rev, 2/18/05 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 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. Do Rest* •` 1 Place hag cal hand 1'htk Ur4149Mr-ige 3 Rcvcr<c bag 1. Uispate uiy Its trash Oh 1.:•4-r: 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 Page 34 of 91 Rey. 2/18/05 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 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://muextensionsnissouri.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. Page 35 of 91Rev. vivos 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. Page 36 of 91Rev. artams Chapter 8 - Cleaning and Maintenance of Drainage Chan Sewers and Inlet Structures A. Description of Activities: nets, Storm 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". B. Locations: The city of Rock Hill 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.

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. Page 39 of 91 Rev. yis/as Implement Phase II public education efforts; public participation efforts to mark inlets with uNo 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 7 5 % 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 o 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. 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 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. 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.

Waste generation, storage, disposal, recycling: NIA - 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 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: R80H 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. Page 43 of 91xcv. arlsros 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 Stormwater 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 oh 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: None at this time. 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. Page 44 of 91 Rev. 2/18/05 E. Waste generation, storage, disposal, recycling: Not applicable. See Chapter 2 and 8 for maintenance. Best Management Practices (BMP): 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. Inspect existing flood management facilities on a specified frequency to determine water quality impacts and exploit opportunities for improvement. 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. 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. Pale 45 of 91 Rev. VI8/05 C. NPDES Permit status: Not applicable H. Training: 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.
