The O&M program shall specify the frequency of inspections and routine maintenance requirements. 2.2 Facilities Inventory An inventory of all municipally owned or operated facilities is maintained by the Stormwater Program Specialist. There is a spreadsheet named Municipal Facilities Inventory in the Stormwater Subfolder within Engineering on the Town of Mooresville OneDrive. This inventory is to be updated as needed by the Stormwater Program Specialist and contains the following information: Facility Name Facility Location Facility Manager Facility Contact Information Watershed Information Facility Activities Any SCM's present at the facility Facility Inspection Frequency Municipal facilities and operations are also mapped on ArcGIS Online to be used for digital inspections. It is the responsibility of the Stormwater Program Specialist to assure this Hosted Feature Layer is updated accordingly if any changes are made in the Municipal Facilities Inventory spreadsheet. 2.3 Facility Operation and Maintenance Plans Individual Operation and Maintenance Plans have been developed for each municipal facility/operation, with the exception of those facilities that have an NPDES General Permit requiring a Stormwater Pollution Prevention Plan (SWPPP). The SWPPP will serve as the'Operation and Maintenance Plan' for that facility and is subject to inspections, training, and documentation requirements as laid out by the General Permit. An Inventory of facilities with an NPDES General Permit is included in the Municipal Facilities Inventory spreadsheet. Stormwater O&M Plans detail the stormwater pollution prevention and good housekeeping practices utilized by the employees at that facility. Each Stormwater O&M Plan also details the frequency of facility inspections, facility specific Best Management Practices (BMPs), regular maintenance activities, employee P a g e 15 training information, and spill response procedures. O&M Plans for each facility are reviewed periodically and amended as needed. Amendments are documented in the appendix of the O&M Plan. Stormwater O&M Plans for each facility are located either at the facility itself or in the Stormwater Program Specialist's office if it is impractical to keep the plan at the facility. The Municipal Facility Inventory spreadsheet will indicate the Plan location. Digital copies of the current O&M plans and past versions/drafts are saved in the Stormwater folder in OneDrive. As new facilities and operations are established, it is the responsibility of the Stormwater Program Specialist to develop an O&M Plan for said facility and establish the appropriate inspection frequency based off the facility's potential for generating pulled stormwater runoff. 2.4 Inspections Municipal Facility inspection information and frequency can be found within the individual O&M Plans and in the Municipal Facility Inventory spreadsheet. Facility inspections are to be conducted via ArcGIS Collector and Survey123. A sample of the digital form can be found in the O&M plan 2.4.1 INSPECTION PROCEDURES 1. Before Inspection a.

If during the inspection the SCM was found not to be working properly are any areas were noted as 'Work Needed (WN)' that cannot be completed by the inspector, the Stormwater Maintenance Supervisor is to be notified immediately to schedule maintenance activities. 3.3.2 FOLLOW-UP INSPECTIONS If an initial inspection shows any areas as'Work Needed' or any other maintenance concerns that can not be conducted at the time of the inspection, a follow-up inspection is required to assure the SCM is back in compliance. To conduct the follow-up inspection, the Inspector is to wait until after the next rain event to visit the site and observe the functionality. When conducting a follow-up inspection, the Inspector should check the box for 'Follow -Up hispection' and follow the procedures from 3.2.1. 3.3.3 ANNUAL INSPECTIONS Town SCM`s fall under the same guidelines as Private SCM` s in terms of maintenance and inspections. Per the Town of Mooresville's Post Construction and Illicit Discharge and Connection Ordinance, SCMs owners are required to submit an Annual Inspection by March 315t of each Calendar year. The Annual Inspection must be completed by either a qualified registered North Carolina professional engineer, surveyor, landscape architect, or any other person otherwise authorized by the Town of Mooresville Stormwater Program Specialist. Under the discretion of the Stormwater Program Specialist, it has been determined that Stormwater SCM Inspection & Maintenance Certification from NC State University is another acceptable qualification. When the box is selected for Annual Inspections additional Survey Fields will populate at the bottom of the Questionnaire and should be completed as follows: a. Name of SCM Owner, Address, and Book and Page Number of the Lot can be found in the Town SCM Inventory Spreadsheet. b. If any areas are noted as'Work Needed (WN)' or any other maintenance is required the option for'Conditional Certificate of Compliance' should be selected i. The inspector should note an estimated date for SCM compliance and plan a follow- up inspection after this date c. For the Seal of the engineer, surveyor or landscape architect attachment field, the Inspector should include a digital image of their credential. If they hold an SCM Inspection and Maintenance Certification, a digital copy of their Inspector Card/Certificate showing their Certification Number and Expiration Date should be submitted here. P a g e 111 3.4 Maintenance Town owned Stormwater Control Measures are to be regularly maintained and inspected as laid out in the Operation and Maintenance Plans developed for each specific qW of SCM. As noted in section 3.2, all SCMs are inspected at least once annually, and most are inspected more frequently on a monthly basis and after significant rain events. The inspector who monitors these structures are to note if any maintenance is required as part of the inspection. If any areas are noted as'Work Needed', the Stormwater Maintenance Supervisor is to be contacted to schedule maintenance. Maintenance activities are to be prioritized along with other MS4 maintenance duties to assure the SCM is operating as designed in a timely manner. 3.5 Personnel The Stormwater Program Specialist is the primary personnel responsible for executing the Operation and Maintenance Program for Municipal Owned/Operated Structural Stormwater Control Measures (sCNrs). The Stormwater Program Specialist is to maintain SCM inventories and manage ArcGIS data. The Stormwater Program Specialist will be responsible for routine and annual SCM inspections, unless otherwise delegated to other qualified personnel. Per the Town of MooresviWs Post Construction and Illicit Discharge and Connection Ordinance, the Annual Inspection must be completed by either a qualified registered North Carolina professional engineer, surveyor, landscape architect, or hold an SCM Inspection & Maintenance Certification from NC State University. The town currently has a number of Professional Engineers on staff qualified to complete inspections and 6 employees under Engineering who hold SCM Inspection & Maintenance Certifications. Outside of annual and routine inspections, these SCMs are visually inspected by other Town employees such as facility managers, building and grounds maintenance personnel and Town inspectors. These parties are to notify the Stormwater Maintenance Supervisor of any issues observed or work that may be needed. The Stormwater Maintenance Supervisor and Maintenance Crew are responsible for any maintenance or repairs needed for SCMs that cannot be conducted on site by the Inspector. The Stormwater Maintenance Supervisor is also responsible for assuring SCMs are regularly mowed and vegetation is maintained per Minimum Design Criteria. Town maintained SCNfs that are unable to be mowed by the Stormwater Maintenance Crew are included in an annual mowing contract with an outside company that is set up by the Stormwater Maintenance Supervisor. 3.6 Documentation & Record Keeping Town Maintained SCM Imrentorym Storinwater OneDrive & ArcGIS Online SCM Plans/As-Buifts- Stormwater OneDrive SCM Inspection Logs - Pre 2020, logged in Town SCM Inspection log Spreadsheet on Stormwater One Drive. hispection Forms are saved in SCM Inspection Binder in Stormwater Program Specialisf s office or in Individual SCM folders on Stormwater OneDrive.

There are three main layers used to map infrastructure: • Drainage Structures- assumed structures Ounction boxes), catch basins, curb inlets, double catch basins, drop inlets, manholes, other/unknown, generic pipe inlet/outlets, pipe inlets, pipe outlets, and slab inlets. o Drainage structure layer also includes a field indicating whether or not a structure is a Major or Minor outfall • Drainage Pipes • Drainage Areas The Town hired a consultant to update Stormwater GIS infrastructure inventory in 2016 where structures were grouped into the above three feature layers. Approximately 194 structures were not classified as a specific structure type. Areas also exist where there is an absence of mapped inventory or there are duplicate features mapped for the same structure. Infrastructure should consistently be updated by Stormwater Personnel when inaccuracies are observed in the field to assure inventory is complete. 4.2.2 INFRASTRUCTURE INSPECTIONS Stormwater maintenance personnel are to routinely inspect Stormwater Infrastructure using the Drainage Structures feature layer and the Drainage Pipes feature layer discussed in Section 4.2.1. 4.2.2.1 DRAINAGE STRUCTURE AND DRAINAGE PIPE CONDITION INDICES Drainage Structures and Drainage Pipes are inspected using the fields 'Condition V, 'Condition 2' and 'Condition 3'. Each condition held will have a drop -down option of 3 different conditions for the inspection criteria. Different attributes will have different condition drop downs depending on the type of structure. Condition I will be the inspection criterion with the most importance, Condition 2 will be the inspection criterion of average importance and Condition 3 the inspection criterion of the least importance. Refer to the following tables for inspection criteria for each structure type: Index for Catch Basins, Curb Inlets, Double Catch Basins, Drop Inlets & Slab inlets Inlet (Condition 1) Ground (Condition 3) most impeo4wa AwkWANNUL- o cracks, no leaks, no block, No sag, no holes, no problem 1 (good) Not clogged, no problem missing no problem 2 (fair) small cracks, some * �M_a H cracks, small leaks, So me sagging (minimal), ci g, minor problem . minor problem minor problem clogged up, large cracks, Large cracks or leaks, missmg block, major Trees or holes around Box, I major problem — problem Major Problems Page 114 Index for Assumed Structures (junction Boxes), Manholes & Other Lid (Condition Box (Condition most � a 1,10 sag, no holes, no no problems 1110 7T least importanc No cracks, no leaks, no 1 (good) problem prc missing block, no problem 2 (fair) SO., minor Some sagging (minimal), Small cracks, small leaks, cracking/misaligned minor problem r7. minor problem 3 (bad) n-dssinglid/severe rees or holes around Box, Large cracks or leaks, missing cracking Major Problems block, major problem Index for Pipe Inlets, Pipe Outlets & Pipe InleiVOutlets Clogging (Condition 1) I L Vegetation (Condition 3) most importance no erosion/no holes least importance no obstructing vegetation 1 (good) I� No Clogging or 0 obstructions 2 (fair) Minor clog/obstruction minor erosion/small holes minor vegetation/needs monitored 3 (bad) 1� Major clog/ obstruction major erosion/ large Major vegetation/trees, brush, sinkholes obstructions need removed Index for Pipe Sy ems, Culverts & Assumed Structures Ground (Condition IL GrAddri (Condition 3) most importance No sag, no holes, no problem Joints aligned, no cracking LC rtance No crackin& good shape 1 (good) 2 (fair) Some sagging (minimal), Slight misalignment of bell minor problem or spigot, minor crackin& Minor cracking, no staining . no staining 3 (bad) Trees or holes around Misaligned/missing bell or Major cracking, pipe out of I I pipe, Major Problems I spigot, major cracking, round, water intrusion water intrusion I When these condition fields are populated, the field for 'Condition hidex' will automatically calculate a rating for the structure overnight using the following formula: Condition Index= (Condition 3 +(Condition 2 * 1.25 )+(Condition 1 *1.5))/3 Condition ratings are on a scale from 1.25 (best condition) to 3.75 (worst condition). Condition ratings will determine prioritization of repairs or potential upgrades. 4.2.2.2 INFRASTRUCTURE INSPECTION PROCEDURES 1. During Inspection a.

If at any time a structure is found to be in need of repair, the inspector should contact the Stormwaber Maintenance Supervisor and submit an iWorQ ticket detailing the issues to be addressed by the maintenance crew I. If several tickets are submitted, the work orders will be prioritized based off the Condition Index Rating, whether or not the problem is deemed a Public Health or Safety Risk and additional factors discussed in Section 4.2.5 Maintenance Prioritization Guidance. *Note: as conditions calculate on a nightly basis, if an immediate Condition Rating is needed to determine repair priority the same day, the Stormwater Program Specialist zvill be able to provide ratingsfor structures in question b. Upon completion of any repairs and a closed out iWorQ ticket, the structure should be reinspected within 60 days to update the condition index fields to their current status, and change the Safety Risk, if needed. The comments field should be utilized to note the date maintenance was completed and any relevant notes. 4.2.2.3 STORMWATER INSPECTIONS DASHBOARD A Stormwater Inspection Dashboard was developed in ArcGIS Online to track the completion of infrastructure inspections, determine condition of structures, and prioritize potential repairs. The dashboard consists of a map and several indicators that can be used to filter what features are visible on the map. This tool may also be utilized by personnel to determine areas for potential Capital Improvement Projects where there are clusters of infrastructure classified under the poor condition rating. Page 116 4.2.3 RAIN EVENT INSPECTIONS Personnel from the Stormwater Maintenance Crew will regularly inspect stormwater inlets in the public right-of-way for any obstructions prior to and during rain events. Designated Public Works field personnel are also assigned to this task when they are not able to complete their normal duties due to weather conditions. Prior to 2021 this was an informal inspection process in which Stormwater Personnel would patrol parts of Town with older infrastructure and areas known for frequent drainage issues while Public Works personnel would be assigned to one of the five plow route sections to patrol. Problems encountered in the field were dealt with accordingly without any procedures or tracking mechanisms. The Town is in current development of an improved rain event inspection program. The goal of this inspection program is to move the Stormwater program to be more proactive in identifying areas that need attention and plan for potential infrastructure repairs or upgrades. The first phase of this program was introduced to Stormwater Maintenance Crew in March 2021 to elicit feedback before being introduced to Public Works personnel. "this section will be updated accordingly once the program is infill implementation. 4.2.3.1 PROCEDURES "procedures will be updated accordingly once the program is in full implementation. 4.2.4 MAINTENANCE The Stormwater Maintenance Crew is responsible for conducting maintenance on all Town owned/maintained stormwater infrastructure. Town Service Requests and Work Orders are tracked through iWorQ.net. All relevant calls, entails and direct requests are logged in this database. Stormwater Personnel use this database to prioritize work orders and plan for materials required to conduct the necessary maintenance. 4.2.4.1 ROUTINE INSPECTION FINDINGS Upon completion of a routine inspection conducted via the procedures in 4.2.2.2, the inspecting personnel will notify the Stormwater Maintenance Supervisor if any maintenance is required and submit a Work Order via iWorQ. Prioritization of work orders will be determined using the guidance provided in section 4.2.5. 4.2.4.2 CITIZEN REQUESTS Citizens are able to submit requests for service via phone call, email, or directly through an iWorQ Service Request. Depending on the nature of the request, the appropriate Stormwater personnel will be dispatched to assess the concern. If the concern is applicable to Town maintained infrastructure (Le Drainage Infrastructure or Drainage Pipes feature layers) the personnel on site is to follow the Inspection Procedures in Section 4.2.2.2 to assess the infrastructure in question. If the infrastructure is determined to be in need of maintenance, the inspecting personnel will contact the Stormwater Maintenance Supervisor and submit a Work Order through iWorQ.net. If the citizen request was originally submitted via iWorQ service request, the ticket will be converted to a work order. Work Orders will be prioritized using the guidance in section 4.2.5. P a g e 117 4.2.4.3 NON -QUALIFYING SERVICE REQUESTS If a citizen service request is determined not to be within the scope of Town maintenance or the infrastructure is not in need of maintenance, the appropriate Stormwater personnel will complete and close out an iWorQ service request ticket detailing appropriate notes about the request and reason maintenance was not deemed appropriate at that time. The party who responded to the non -qualifying issue should do their due diligence to attempt to put the citizen in contact with the proper party to address their concern. 4.2.4.4 REINSPECTION OF REPAIRS/ MAINTENANCE Within 60-days upon completion of maintenance, infrastructure will be reinspected and assigned an updated Condition Index Value. The comments field should be utilized to note the date maintenance was completed and any relevant notes. 4.2.5 MAINTENANCE PRIORITIZATION GUIDANCE Condition Index Rating Action Description —Timerine for Repair Safety N/A Immediate Repairs prioritized 24-48 hours* Concern or Maintenance Needed by criteria on Pages Property 18 & 19 Damage Poor 75 _< Maintenance Need—ed Repairs prioritize --- Y-3 —weeks* by criteria on Pages ___�.17-2.74 18 & 19 Fair Monitor Condition Structures As schedule reinspected permits _<216 annually No action re quired Structure Stays On Structure stays routine inspection on routine schedule inspection * Table is to be used as a baseline estimate of the timelines in which maintenance is to be completed on infrastructure. See Poor Condition section for list of outsidefactors which may impact the time needed to complete maintenance. Poor Condition Infrastructure that is inspected and assigned a condition index rating 2.75 or higher is classified as being in poor condition. Poor Condition Structures are allocated to the Repair Prioritization fist based off Safety Risk, Damage to property and the Condition Index value assigned to the infrastructure upon completed inspection. Repairs that pose a public health and safety risk or cause damage to property will automatically jump to the top of the Repair Prioritization list regardless of Condition Index Value. Structures that are not deemed as such will follow these repairs on the list in order of Condition Index Value from worst condition to best condition. Condition is meant to be a baseline representation of the P age 118 state of structures based off initial field inspections. Pipes and structures on the repair prioritization list will be addressed by maintenance personnel in the order listed unless outside factors including, but not limited to the following effect the feasibility of immediate maintenance: Location Weather Conditions Accessibility Easements/ Right -of -Entry Duration of repair Equipment required Cost and availability of materials In House or Contracted out If a repair or maintenance is not feasible, maintenance personnel will move down the list to the next highest priority repair to address. Fair Condition Infrastructure that is inspected and assigned a condition index rating between 2.17 and 2.74 is classified as being in fair condition. Infrastructure that is rated as Fair Condition will not be added to the work order fist unless signs of increased damage show over time. Fair Condition Structures will be monitored and reinspected annually to determine changes in condition. Poor Condition Structure Maintenance, non - infrastructure related maintenance and regularly assigned work duties will take priority over fair condition structure maintenance by Stormwater personnel. Proactive maintenance will be conducted on these structures as workload permits and addressed in order of Condition Index Value unless feasibility is limited by the factors listed in the previous section. In that event, the next highest priority infrastructure will he addressed. Good Condition Infrastructure that is inspected and assigned a condition index rating of 2.16 or below is classified as being in good condition. This infrastructure requires no action or submission of a work order. Infrastructure and pipe systems under this classification are fully operational and not in need of any maintenance to improve functionality. Good Condition infrastructure will stay on a routine inspection schedule. 4.2.6 PERSONNEL The Stormwater Program Specialist is the primary personnel responsible for maintaining Stormwater GIS data and assure applications are properly utilized. The Stormwater Maintenance Crew is the primary personnel responsible for inspecting and conducting maintenance on the stormwater conveyance system.

The Street Sweeper works to remove dirt and debris from the streets and gutters within Town and minimize the amount of pollutants that are washed off the streets and gutters and into the storm drains. 4.3.1.1 STREET INVENTORY The Town of Mooresville Powell Map found on the ArcGIS Enterprise Server is used to track which streets and roads within the corporation limits are maintained by the Town or will eventually be turned over to the Town for maintenance. 4.3.1.2 SWEEPER ROUTES The street sweeper runs 4-5 days a week and works off of 10 different routes developed to follow brush pick-up routes from the sanitation department and to assure main roads and frequent problem areas reach a greater level of service throughout the year. Routes are as follows: Red Monday Red Tuesday Red Wednesday Red Thursday Red Friday • Blue Monday • Blue Tuesday • Blue Wednesday • Blue Thursday • Blue Friday As there is only 1 designated street sweeper the Red and Blue routes run on alternating weeks in hopes of reaching adequate coverage of serviced areas. It is the responsibility of the street sweeper operator to keep track their completion of their routes. Sweeper Example Scenarios The operator decides to kick off the fiscal year on a red week. The operator starts the work week at a designated point on the Monday Red Route. The operator will work their way through the route until the end of their designated shift that day and note the area they stopped at to pick up on in 2 weeks on the next Red Monday. The same procedure will be followed for the rest of the week utilizing the Tuesday - Friday Red Routes and for the following week utilizing Monday -Friday Blue Routes. Upon completion of a full route the operator will start the route over from their last designated starting point. P a g e 120 If the street sweeper operator works on a 4-day work week such as Monday -Thursday, it is the responsibility of the operator to assure the Friday route is completed/ receives adequate coverage another day during the week. The Stormwater Maintenance Supervisor may approve a modified schedule for the operator to have an earlier start time one or more days to accommodate this. *Operator may be pulledfrom street sweeping routes if there is an area that needs immediate attention, or if there are wet weather conditions that day that would prevent the sweeperfrom effectively cleaning the roadways. 4.3.1.3 TRACKING MECHANISMS Effectiveness of the street sweeping program will be tracked based on the frequency in which streets are swept and by the quantity of pollutants removed. 4.3.1.3.1 STREETS CLEANED The Town has one GPS unit dedicated to the Street Sweeper. This GPS unit is used to track completion of routes through Fleetmatics. At the end of each month, the Stormwater Program Specialist will pull the data from the Fleetmatics website to load into a hosted feature layer on ArcGIS Online. This Web Map can be used to determine the current level of service at the end of each year, see which areas are not receiving enough attention and address citizen inquiries. The Stormwater Program Specialist will also develop a map at the end of each month to provide to the Stormwater Maintenance Supervisor to review with the operator. Maps will be saved in the Storrawater OneDrive under Street Sweeping. 4.3.1.3.2 ESTIMATED QUANTITY OF POLLUTANTS REMOVED Pollutants that are removed utilizing the street sweeper are dumped in the decant area located at the Public Services Operations Facility. When the decant area is full the waste is to be disposed of at the Iredell County Landfill. Each load is weighed upon arrival and the quantity is billed to the Town of Mooresville. The decant area is primarily used by the street sweeper but is also utilized to dispose of waste from several other departments. The tonnage removed from decant is to be used as an estimate of the quantity of pollutants removed from street sweeping activities with some margin of error. The following table shows the quantity of pollutants removed monthly from decant in the most recent fiscal year: MONTH TONNAGE AMOUNT Jul-20 29.42 1176.8 Aug-20 9.73 389.2 Oct- 20 27.62 1104.8 Nov-20 22.47 898.8 Jan-21 55.17 2206.8 Feb-21 28.08 1132.2 Mar-21 44.26 1770.4 M 21 43.86 1754.4 13.54 541.6 TOTALS 274.15 10975 Page 121 4.3.1.4 ESTIMATED LEVEL OF SERVICE STREET Frequency Residential 5 times per year Main Street Bi-WeekIy NC150 Monthly Brawley School Road Every 6 weeks *Table to be updated at the end of each Fiscal Year based off monthly averages of streets swept 4.3.2 PARKING LOT MAINTENANCE AND CLEANING The Town of Mooresville maintains approximately 51 Parking lots between Town owned facilities, parks and public parking areas. Parking lots equipped with curbs are routinely cleaned by the Street Sweeper on an as needed basis. Parking lots are also to be regularly inspected and cleaned by facility personnel per the guidelines in the facility specific Operation and Maintenance Plans and the Parking Lot Maintenance and Cleaning Standard Operating Procedure. 4.3.3 PERSONNEL The Stormwater Equipment Operator responsible for Street Sweeping duties is the primary personnel responsible for carrying out street and parking lot cleaning. This position reports to the Stormwater Maintenance Supervisor who is responsible for delegating tasks to the operator. The Stormwater Maintenance Supervisor is responsible for obtaining the billing totals from Iredell County Land Fill to determine the quantity of pollutants removed from decant area at the end of the Fiscal Year. The Stormwater Program Specialist is responsible for documentation of this program element. The Stormwater Program Specialist is to modify routes, track completion of sweeping and develop maps to detern-dne the effectiveness of this program 4.3.4 DOCUMENTATION AND RECORD KEEPING Street Inventory- POWELL Map on ArcGIS Online Street Sweeper Routes- Map on ArcGIS Online, printed copies Streets Sweeping Completion- Fleetmatics, ArcGLS Online, Individual Maps on Stormwater OneDrive 0 Quantity of Pollutants Removed- Spreadsheet on Stormwater OneDrive 4.4 Program evaluation This program will be evaluated at least once annually by the Stormwater Program Specialist with the assistance of other personnel responsible for executing the MS4 Operation and Maintenance Program.

Taking this into consideration, it was decided that all Town employees should receive basic Stormwater training at least once during the fiscal year. Certain departments are more likely to deal with Stormwater concerns as a part of their day-to-day duties and may receive additional trainings as discussed below, 5.2.1 NEW EMPLOYEE TRAINING All Town employees are to attend New Employee Orientation put on by the Human Resources Department within the first quarter of their employment. Employees that attend this orientation receive an introductory handout that discusses general stormwater information such as the definition of stormwater, stormwater pollution, and what employees can do to prevent or minimize stormwater pollution. 5.2.1.1 DEPARTMENT SPECIFIC CHECKLISTS New employees based in the maintenance departments at the Public Operations Services facility and Building and Grounds Maintenance Shop receive additional training in the form of a New Employee checklist. The checklist describes specific actions employees can take to minimize or prevent stormwater pollution at the Public Services Operations Center/ Building & Grounds Maintenance Shop, as well as at their work sites. P a g e 123 5.2.2 ANNUAL EMPLOYEE TRAINING All Town employees who have a registered Safety Skills account are required to complete Annual Stormwater Training. These trairdngs become active in Safety Skills January 1st of each calendar year and are due by December 31$1. Three separate trainings are loaded into Safety Skills: • Illicit Discharge and Elimination Presentation (created in 2020 by Stormwater Program Specialist) • Pollution Prevention and Good Housekeeping Presentation (created in 2020 by Stormwater Program Specialist) • Stormwater Pollution: Baseline Best Management Practices'Microlearning' (training video with an interactive quiz provided by Safety Skills) 5.2.3 FACILITY MANAGER TRAINING In 2020 the 2016 versions of each facilit/,s Operation and Maintenance Plan were collected and updated by the Stormwater Program Specialist When these plans were updated and redistributed to the facility managers (or appropriate building/operation contact) the Stormwater Program Specialist completed a training called "Introduction to the O&M". Upon completion of this brainin& the facility manager was presented with a Stormwater Facility Manager Checklist to sign off on verifying they received training on the contents of the O&M plan and would follow the Best Management Practices specific to their facility. 5.2.4 ADDITIONAL TRAININGS Additional training may be provided under the discretion of the Stormwater Program Specialist. Trainings may be developed based off findings during routine or annual facility inspections, if reoccurring stormwater issues arise in the Town that need to be addressed, or if job specific duties call for additional stormwater pollution prevention or illicit discharge detection training. Trainings may be provided in person or in an online presentation format depending on the number of personnel the lesson is targeted to and the feasibility to conduct in person training. 5.3 Training Frequency New Employee Training- Once, upon hire with The Town of Mooresville (all employees) Department Specific Checklists (Ops & B&G)- once, upon hire within a field position working out of the Building and Grounds Maintenance Shop or Public Operations Center Pollution Prevention and Good Housekeeping- Annually (all employees) Illicit Discharge Detection and Elimination- Annually (all employees) Stormwater Pollution: Baseline Best Management Practices- Annually (all employees) Introduction to Operation and Maintenance Plans- Once, upon receival of new O&M plan or entering a new facility manager position (managers or designated facility contact only) Facility Manager Checklist- Once, upon receival of new O&M plan or entering a new facility manager position (managers or designated facility contact only) Page 124 5.4 Training Procedures 5.4.1 NEW EMPLOYEE TRAINING PROCEDURES HR was provided with a PDF version of the updated'New Employee Stormwater Brochure' in 2021. This brochure is to be distributed at New Hire Orientation by the HR personnel responsible for leading these sessions. *In past years, the Stormwater Program Specialist attended these sessions in person to present a short slide shozv on Stormwater Services in addition to the handout. This practice was discontinued due to time limitations and the extensive amounts of other information covered during orientation. The following steps should be taken to assure New Employee Stormwater Brochures are updated, distributed, and tracked: Check with Human Resources to assure they have adequate copies on hand of the New Employee Stormwater Brochure o The brochure is saved on the Stormwater OneDrive under FY21 Training and can be provided to the HR office to print additional copies. • Assure the brochure is up to date with current contact information for the Stormwater Program Specialist & Stormwater Maintenance Supervisor • At the end of the Fiscal Year (June 30th) reach out to Human Resources for a count of how many new employees went to Orientation during the reporting year. • The number of employees who received this brochure should be logged in the'FY## Training Log' for that reporting year. • A list of all new employees can be requested from HR as well if further documentation is deemed necessary. 5.4.1.1 DEPARTMENT SPECIFIC CHECKLISTS Blank copies of New Employee Checklists are located in the Training Tab of the Operation and Maintenance Plans for the Building and Ground Maintenance Shop and Public Operations Center. Facility Managers/designated facility stormwater contacts for these facilities are the primary personnel responsible for assuring the checklist gets distributed. The following steps should be taken to assure New Employee Checklists are completed and returned to the Stormwater Program Specialist • When a new employee is hired out of one of these locations the facility manager or supervisor will provide the employee with the checklist to complete. • The facility manager or supervisor is to provide a copy of this checklist to the Stormwater Program Specialist upon completion. • The number of employees who completed facility specific checklists should be logged in the 'FY## Training Log' for that reporting year. "*Stormwater Program Specialist may request a list of all new hires from Human Resources at the end of the year to assure all necessary personnel completed a checklist P a g e 125 5.4.2 ANNUAL EMPLOYEE TRAINING Employee training runs on the calendar year January 1st -December 316t. Completion of these trainings is mandatory for all employees. Risk Management personnel tracks completion of assigned trainings. At the end of the calendar year, Supervisors and Department Heads will be notified of the employees who have outstanding training to be completed by December 315t. At the end of the Fiscal Year, the Stormwater Program Specialist is to contact Risk Management to obtain records of employees who completed training for NPDES Permit Annual Reporting. The number of employees who completed annual training should be logged in the'FY## Training Log' for that reporting year. At the beginning of each calendar year, the Stormwater Program Specialist is to contact Risk Management Personnel to assure stormwater training will be assigned to all employees to complete that year and provide them with any updated trainings. Content included in Annual Training is to be reviewed for relevancy once annually. The content is to be updated accordingly based off results of facility inspections, documented town issues, implementation of new BMP`s, etc. 5.4.3 FACILITY MANAGER TRANING All existing Facility Managers completed a Facility Manager Checklist in Fiscal Year 2021. Completed checklists are kept with the Stormwater Program Specialist's files. Blank copies of this form are saved under FY21 Employee Training on the Stormwater OneDrive. In the event of a change in personnel, the Stormwater Program Specialist is to schedule a meeting with the new facility manager within 90 days of their employment to complete Introduction to the O&M training.
