INTRODUCTION The City of Prior Lake owns and operates a Public Works Garage which stores and repairs trucks, tractors, trailers, lawn and garden tractors, lawn and garden equipment and oil and gas machinery and equipment. In addition, the City of Prior Lake also stores sand, de-icing salt, and gravel for the purpose of road maintenance and repair activities. Because these activities are identified by the Pollution Control Agency's list of Standard Industrial Classification (SIC) codes, the City of Prior Lake is required to apply for permit coverage. A. MPCA NPDES Phase II Storm Water Permit The City of Prior Lake is submitting this permit to satisfy the 1987 Amendments to the Clean Water Act. These amendments were a two-phased comprehensive national program to address pollutants in storm water runoff. The program covers construction sites, industrial activities, and municipal storm sewer systems. As part ofthe second phase (phase II) of these changes, the City of Prior Lake falls under the category of smaller municipalities (populations of less than 100,000) which were previously exempt from the program. . J These storm water regulations are part of the National Pollutant Discharge Elimination System (NPDES) permit program. As of March 10,2003, the City of Prior Lake will be required to obtain a permit to discharge storm water from its Public Works Garage, from the Minnesota Pollution Control agency (MPCA), which has received permitting authority from the Environmental Protection Agency (EPA). The City of Prior Lake understands that the intent ofthese storm water regulations is to improve water quality by reducing or eliminating polluted storm water runoff. Specifically this plan will be in place to reduce or eliminate the exposure of oil and grease, pesticides, fertilizers, sediment, de-icing salts and other chemicals used by the City, to storm water. With this understanding, the City of Prior Lake has developed Best Management Practices (BMPs) to reduce or eliminate the exposure of City activities into the storm water system to the greatest extent practical. II. GOALS AND OBJECTIVES This Storm Water Pollution Prevention Plan (SWPPP) was prepared by the City of Prior Lake with the intention, of developing a program, which, to the best extent possible, would improve water quality by reducing the exposure of pollutants to the storm water discharges originating from the City's municipal operations. In accordance to the Minnesota General Storm Water Permit authorization to discharge storm water associated with industrial activities under NPDES/SDS Permit Program, This Storm Water Pollution Prevention Plan should at a minimum: 1. Identify potential sources of pollutants, which may affect the quality of storm water discharges. 2. Employ the use of appropriate erosion control measures and best management practices (BMPs) to reduce the impact of any pollutants, which may reach storm sewer discharges. 3. Implement practices, which will reduce pollutants in the storm water discharges to the greatest extent practical. 4. Certify that the NPDES Phase II Industrial Discharge Permit covers all storm water discharges from the City of Prior Lake Public Works Garage. 1 In addition, a copy of the SWPPP will be maintained on site and readily accessible. By meeting these stated goals to reduce the pollutants contained in storm water to greatest extent practical, the City of Prior Lake will meet the objective of NPDES Phase II Industrial Discharge Permit. III. MANAGEMENT POLICY The City of Prior Lake acknowledges the authority of the MPCA, to permit the discharge of storm water associated with industrial activity under the NPDES Phase II program. By submitting this SWPPP document, the City of Prior Lake will meet the terms and conditions contained within the Minnesota General Storm Water Permit. The City of Prior Lake will also develop an implement best management practices to minimize pollution to storm water discharges and will continue to evaluate operations, materials handling and storage practices to make these practices more environmentally safe. A. SWPP Organization The following list outlines the people responsible for the administration, construction, and maintenance of the City of Prior Lake storm water system. In addition, these individuals are also responsible for the activities associated with the operation, policies, and procedures within the Public Works Garage and its workers. This section also key people involved in implementation of this SWPPP, this section details the persons title and the direct responsibilities they will have in implementing this plan. ill , B. Responsible Parties Sue McDermott - City Engineer C. Description of Activities The following summarizes the activities associated with each area of responsibility: 1. SWPPP Manager Sue McDermott -City Engineer SWPPP team leader and administrative program. Maintains materials, inventories, and handling storage practices. Manages for team inspection and maintenance of best management practices. Plans and schedules education-training programs 2. Site Manager _ Performs detailed site inspections and assessments. Manages turf maintenances, litter and erosion control measures. Coordinates clean up of spills and releases. " D. Site Operations The City of Prior Lake's Public Works Garage is designed to perfonn the following activities: storage and maintenance for all of the City's maintenance vehicles in addition to the storage of the sand, salt, and construction materials used in road maintenance and repair activities. The City's maintenance vehicles are washed and repaired at this site. These sites also are act of storage facilities for all snow plowing materials, road-deicing materials, pesticides, and herbicides we used to weed control and agricultural spraying. iI , IV SITE ASSESSMENT AND PROCEDURES In this section of the SWPPP, the site conditions are examined, potential problems area identified, Best Management Practices (BMPs) are identified and a detailed description of the procedures used to meet the terms of this permit are presented. A. Site Information and Description This section will be completed based upon a site inspection. t B. Drainage System Characteristics This section will be completed based upon a site inspection. C. Evaluation for Significant Materials Exposure A list of the activities and operations, which take place at the Public Works Garage, are found in the Appendix 2. In addition, Appendix 3 lists the significant materials, which have the potential of becoming a source pollutant, if exposed to stonn water discharges. The goal ofthis SWPPP is to prevent the exposure of significant materials before they are allowed to enter the storm sewer discharges. This section evaluates areas and opportunities within the site where significant materials are stored and evaluates the risk of these materials exposure to storm water discharges. It should also be noted that to date, there have been no recorded incidents of a significant spill or discharge from this facility into the City's stonn sewer system 1 D. Best Management Practices A required element of this SWPPP is to introduce and adopt Best Management Practices (BMPs) which creates ways to minimize the exposure of potential pollutants to receiving water bodies. There are a wide variety of BMPs, which include operational activities, a change in procedures or structural devices. An example of operational BMPs would be training programs or inventories, which could identify possible risks within the current operational practices. Once these risks are identified, change of procedure BMPs can be put into action, which would eliminate potential risk. These actions could be a simple as a change in storage facility or the extreme measure of the total ban of a product or procedure. Structural BMPs are typically constructed measures such as ponds, detention basins, skimmers, or grit chambers. These BMPs are designed to remove pollutants from storm water, or create a barrier between the pollutants and the storm water such as berms, dikes, and buildings. The following lists the sites and conditions of the potential pollutants and describe BMPs, which the City will employ to prevent the possibility of exposure to stonn water. ia J. Storage Areas · Cover and/or enclose stored materials to prevent contact. · Divert storm water around storage areas. · Stock/pile material to minimize surface area exposed to precipitation. · Practice good housekeeping measures such as frequent removal of debris. · Install treatment measures to remove pollutants from runoff prior to discharge from the site. Waste Storage Areas · Minimize waste generated at the site. · Store indoors or in covered dumpsters or under other types of cover. · Divert stonn water around areas. · Install treatment devices to remove pollutants from runoff prior to discharge from the site. Loading /Unloading - Materials Handling .waste storage areas loading/unloading and other material handling areas loading/unloading and other material handling areas · Cover loading and unloading areas. · Divert stonn water around areas. · Where dust is likely to be generated during material handling, install equipment or change methods of handling to minimize or eliminate dust generation. · If liquid materials are being loaded or unloaded and if loading/unloading areas drain to stonn sewer inlets, prevent material from getting into the stonn sewer inlets. " · Install treatment measures to remove pollutants from runoff prior to discharge from the site. Outdoor Storage · Store drums inside (if allowed by Fire Marshall or insurer). · Prepare and train appropriate employees in dealing with spills and leaks properly, use dry clean-up methods when possible. · Install impervious surface underneath drums. · Prevent run-on to and runoff from tank and drum storage areas, provide adequate containment to hold spills and leaks. Exterior Obsolete Vehicle Storage · When possible, dispose of unused equipment properly, or move indoors. · Drain fluids from equipment. · Cover equipment. · Divert storm water around equipment. floor, sink, or process wastewater connected to a storm sewer Vehicle Washing · Conduct washing indoors or in a covered area. · Contain and recycle washwaters. · Discharge washwaters to sanitary sewer with permission of the receiving wastewater treatment authority. · Do not allow off-site discharge of wash water. · Evaluate washwater from steam cleaning of parts contaminated with oils, greases or solvents that is not recycled to determine if it is hazardous. Dispose of hazardous sludge and washwater appropriately. i Fueling Areas · Minimize run-on of storm water into the fueling area. · Use dry clean-up methods for fuel area rather than hosing down the fuel area. · Train appropriate employees on proper fueling practices. · Install treatment devices to remove pollutants from runoffbefore it discharges from the site. Vehicle and Equipment Dismantling and Maintenance · Prevent spills during dismantling process. · Contain any leaking or dripping fluids. · Store dismantled vehicles and equipment and parts out of concentrated storm water flows (ditches, channels). · Cover parts that have been contaminated with oils, greases or solvents. · Store batteries in a non-leaking, covered container. · Promptly transfer used fluids to the proper closed container; empty drip pans when they fill. Spills of Liquid Materials · Stop the source of the spill immediately. · Contain the liquid until cleanup is complete. · Deploy oil containment booms if the spill may reach waters of the state or drainage ways to waters of the state. · Cover the spill with absorbent material. · Dispose of cleanup materials properly. · Report the spill to the Duty Officer, when appropriate. Areas of the Facility With Unstable Soils · Minimize run-on from adjacent areas. · Seed and mulch or sod low traffic areas. · Stabilize high traffic areas including vehicle entrances, exits, loading, unloading and vehicle storage areas. · Prevent sediment from unstabilized areas from leaving the site. , E. Employee Training Program As part of the Surface Water Pollution Prevention Plan, the City of Prior Lake will administer an employee-training program. This training program will include all of the public works personnel who are directly or indirectly involved in activities occurring within the Public Works garage and with the equipment and materials stored at the garage. Each of these employees will attend at a minimum one training session over viewing BMPs, the SWPPP, handling significant material and spill response procedures. These training sessions will be a combination of on-site workshops and presentations as well as outside training from industry offered classes. The goal of this program is to educate employees involved in maintenance and repair activities in the City owned facilities. Training shall include BMPs in everyday activities such as good housekeeping, preventative maintenance, proper material handling, operations following spills, and making observations of pollution prevention potential impacts. This training shall be designed to develop proactive attitudes towards pollution prevention and have each employee take on a personal responsibility to contribute to a clean, safe, and pollution-free worksite. 11 .. The program basics will define the problem, define the program, describe how individuals can make a difference in the program, encourage and require participation in the program and include pollution prevention responsibilities as part of an employee job description. These seminars will also solicit and list comments received from employees on the overall program and suggestions for improvements to the program. F. Preventative Maintenance Program This program will require regular inspection and maintenance of storm water management devices both internal and external to the public works garage. This program will require an inspection, as well as testing ofBMPs in place and to look for, identify conditions that could result in breakdowns or failures in the existing Pollution Prevention Program. These inspections should be conducted once every two months, and should include both inside activities and outside activities. It should be noted that these will also be conducted at least twice a year during storm conditions where runoff is accumulating in the storm water system. As part of this program, all catch basis, ditches, and work areas will be checked for cleaning and maintenance schedules to see if they were adhered to. G.

Spill of Pesticides & Fertilizer Procedure A. Minor Spills - A minor spill small enough to be controlled, contained and cleaned up using available equipment and materials. Our most likely procedure of a minor spill would be to contain the spill using sand or a similar substance. Next you must determine whether it is appropriate to stop the source of the spill or to limit the flow. Protect yourself before proceeding - wear appropriate protective equipment. Do not allow anyone to walk in spilled area. Prevent vehicles from driving over spilled area. For traffic control materials, see page 9. I. Container Spills - If the material starts to spread, contain by diking with sand, soil or absorbent clay. Do not allow material to enter storm sewers, waterways, etc. or pool at well heads. 2. Or nearest source of sand or soil is listed on page 9. Tools for moving these materials are listed on page 9. Our front end loader is listed on page 9. 3. After emergency containment is completed, start the recovery and clean up operation. When first response and evaluation of the situation are completed, F:\ WPWlN\NPDESPHASEIl\Forms\lncident Response Plan.doc notify appropriate authorities per call list on page 1 and request appropriate assistance and materials from emergency contacts listed on page 1. 4. Do not allow anyone to smoke near the spilled pesticide or fertilizer, or to provide any other potential ignition source. 5. Wear appropriate protective equipment. This equipment is listed on page 9. 6. Do not hose down the spill because hosing spreads the spilled material. Small spills within a paved area may be cleaned up using a low pressure water line and as little water a possible as long the spill is contained. t F:\ WPWlN\NPDESPHASEll\Forms\lncident Response Plan.doc v. MONITORING AND REPORTING This section of the SWPPP describes the details of the periodic site observations and required site inspections. With each of these site evaluations the inspector will be looking at the site's stormwater characteristics noting any changes since the last inspection, breeches in the structural BMPs, or any evidence that would suggest pollutants in the storm water runoff from the site. Based on the results of these inspections, the City of Prior Lake staffwill annually evaluate the effectiveness of the selected BMPs and if necessary, BMPs that are more appropriate may replace the existing practices. A. Monitoring Program As part of the requirements of the NPDES permit, the City of Prior Lake must conduct regularly scheduled site inspections of the Public Works Garage. This activity fulfills the permit requirement that conditions are kept current and that if changes in design, operation; or construction is put in place, the SWPPP must be updated to reflect the new conditions. These inspections also detail the condition of the BMPs in place, the storage, aild handling of significant materials, and the overall condition of the storm sewer system. Appendix 4 of this document includes a Site Inspection Form provided by the MPCA. As part of each inspection, a Site Inspection Form will be completed and inserted into the SWPPP. ;; , The inspection schedule, as required by this pennit, will be once every two months during non-frozen conditions. For the City of Prior Lake, the inspection period will be between the months of April and November. In addition, at least one of these inspections should occur during rainfall conditions so that stonn water flows can be observed. In addition to filling out a Site Inspection Form, the inspector will also be making sure that the site meets the current SWPPP descriptions. The inspector will also look for new exposures to materials not included within the original SWPPP. If these inspections show that corrective action needs to be taken, the permit requires that this action take place within 30 days of the findings ofthis report. B. Reporting Additional terms of this permit have specific reporting requirements. The reporting activities consist of four primary tasks: 1. Documenting the process involved in preparing the SWPPP. 2. Documenting, evaluating and implementation of the BMPs. 3. Recordkeeping. 4. Submittal of all annual reports. " Keeping updated and accurate records is required by SWPPP regulations. The auditing of stormwater records for permitted facilities is used by the MPCA as the enforcement tool of the pennit process. The records required by the MPCA stormwater permit are defined in the permit as follows: A. The SWPPP shall be maintained and updated for the duration of the permit (4/l0/2003 - 4/l0/2008). B. A copy of the SWPPP, shall remain on the permitted site at all times and be available upon request. In addition, the City of Prior Lake shall maintain the following records for a minimum of three years after the life of the permit: A. Date of inspection B. Findings of inspections C. Corrective actions taken D. Documentation of all changes to the SWPPP E. Methodology for planning and implementing selected BMPs and SWPPP. ; Each of the annual reports will also contain: A. A brief summary of the SWPPP. B. Certification that the SWPPP has been completed. C. List any spills or known contaminants ofthe stormwater from significant materials and the corrective action taken to prevent future spills, or the contamination of stormwater. D. Description of inspections, date of inspections, finding of inspections, and corrective actions taken.
