Storm Sewer System Information 1.1 Population: -Permanent: 7478 -Basis of Population statistic: 2004 Census -Seasonal: n/a -Method used to create seasonal estimates: n/a 1.2 Growth Rate: 2.2 1.3 Jurisdictional Area: 14.9 square miles (City Limits + ETJ) MS4 Service Area: Same 1.4 MS4 Conveyance System The City of Conover storm water system includes drainage infrastructure such as inlets, basins, manholes, pipes, culverts, bridges, ditches, and swales. These structures contain and move storm water that naturally gravitates to privately owned storm water systems and receiving streams of the State. The City has (13) thirteen receiving streams throughout our area that direct waters to the Catawba River Basin. Open channels make up the majority of the City and privately owned systems throughout Conover. City Crews provide maintenance to the City System by the following methods: • Open Channel / Ditch -line Maintenance -- Operation includes cleaning, clearing and restoration of open ditch -lines within the City rights of way. Providing riprap stabilization and seed/grass measures are commonly used to correct, minimize and control erosion issues in these areas. • Drainage Pipe Maintenance - City Staff provides pipe installation for property owners desiring to pipe areas within the public right of ways. Other related work may include; catch -basin construction, catch -basin and pipe cleaning, catch -basin and pipe repair, erosion control measures and spill hazard response. • Sweeping - The City provides curb -sweeping service for removal of trash, litter and other debris. Additionally, they may respond to emergency situations possibly involving hazardous substances. • Flushing - The City provides flushing service to the downtown curbed streets and other areas on an as needed basis. • Litter / Dead Animal Collection - This activity includes the removal of trash, debris and dead animals from City maintained streets, parking lots and walkways. • Leaf Collection - The City has (2) two options for leaf collection services for its residents. Citizens may bag their leaves in clear bags or rake loose leaves to the curb or ditch -line boundaries to receive vacuum service. Residents are asked to keep ditch -lines free of leaves at all times. The city employs (3) Full -Time positions for system maintenance. The system is inspected yearly for maintenance problems and cleaned following rain events. 3 1.5 Land Use Composition Estimates Residential: 69.5 % Commercial: 9.1 % Industrial: 16.4 % Open Space: 5.0 % Total: 100 % 1.6 Estimate Methodology Land Use Percentages were calculated based on the zoning information maintained by the Planning and GIS Departments. By grouping the various zoning districts within the City of Conover into 4 main categories, using Arclnfo software and calculating the total area of each category, percentages were calculated by dividing each category by the total area of Conover. 1.7 TMDL Identification NONE 2.

Continue use of local government Utilize local cable television to cable Environmental 6 remind citizens of X X X X X government seasonal stormwater Coordinator channel issues and water duality messages. 7.1.2. Target Audience The City of Conover will target a majority of the community with respect to Public Education. Households, farmers, businesses and industry, gas station owners and gardeners are some of the citizen groups targeted. Every member of the community has been targeted for education, because only with citizen participation, can we reduce or remove pollution from the stormwater system. 7.1.3 Target Pollutant Sources Specific pollutants being targeted by Conover's program include soils & silts, trash, bacteria, yard waste and grease / oils that may intentionally or inadvertently be discharged into the system. These pollutants are common among storm water systems located within urban and suburban areas and are impacted by construction site development. Such pollutants may be reduced or eliminated by following proper principles in the disposal, transportation, use and containment of the components. 7.1.4 Outreach Program For the past several years Conover has provided Public Education through these efforts: • Use of local government cable channel • Use of Conover Neighbors newsletter to all utility customers • Development and distribution of educational handouts to residents • Display of posters and storm water information at various public functions such as National Night Out, Earth Day, Catawba River fest, Conover Farmers Market. • Storm water related brochures placed in public areas and local vet offices. We plan to continue those practices and expand efforts by further development of our web site, partner with the local storm water working group in offering additional educational programs to local schools / civic organizations and working with developers and contractors to develop and implement procedures to address construction run-off. 7.1.5 Decision Process The City of Conover feels that the practices currently used and those proposed blend well with our community efforts to keep the public informed on all issues. Efforts such as these have been successful for our community. Expanding on current practices will help keep the cost of the program down for our residents. 7.1.6 Evaluation The Public Education Program will be evaluated every year by referencing the suggested BMP's and reporting any activity in the annual report to the State. By tracking the number of publications produced, and comparing the amount of information provided to the public through mailers, brochures and web hits, a count of citizens reached can be calculated. 10 7.2 Public Involvement and Participation 7.2.1 BMP Summary Table BMP Measurable Goals Yr 1 Yr Yr Yr Yr Responsible 2 3 4 5 Party/Position Maintain existing Stormwater Advisory 1 Citizen Board to illicit Environmental Advisory Group public input and X X X X X Coordinator advice on stormwater issues.

Homeowner associations, neighborhood groups, and local businesses and industries are just a few of the groups targeted. Every member of the community has been targeted for involvement, because only with citizen participation, can we reduce or remove pollution from the stormwater system. 7.2.3 Participation Program The City of Conover realizes the importance of public involvement in the overall success of the Stormwater Management Plan. A citizen's Stormwater Advisory Board has been established to hear items related to stormwater, provide a public contact and venue for stormwater issues, and offer recommendations to the City Council. Continue to make available storm drain stenciling materials for local volunteer groups who are interested in civic projects or raising water quality awareness. Continue to involve local scouts who have participated in past years in stenciling drains, as well as public postings for stenciling opportunities. Promote public involvement in local litter pick up campaigns such as the existing Keep Catawba County Beautiful program. Encourage citizen participation at biannual hazardous household waste disposal days. Continue the successful curbside and specialty drive to recycling programs. 7.2.4. Decision Process The City of Conover is going to develop the public involvement and participation program using the BMP's suggested. These measures were decided upon because they involve not only the general public, but give groups who are interested in water quality and the environment the opportunity to participate in programs and contribute. Since developers will install storm drains as part of stormwater infrastructure, we will require that the drains castings contain a "drains to stream" message. 7.2.5 Evaluation The success of this measure will be evaluated by determining if the BMP's listed above have been accomplished and reporting accomplishments annually to the State. 12 7.3 Illicit Discharge and Elimination 7.3.1.

Maintain mechanism for reporting of 4 IDDE Reporting X X X X X Public Works Illicit Discharge Detection. 7.3.2, Storm Sewer Map The City has developed a storm sewer system map identifying MS4 within the street rights of way and the system outfalls. Elements shown include catch basins, curb inlets, pipes, culverts, swales and ditches that collect water and eventually discharge into local streams and surface waters. The map is comprised of a digital GIS base map with infrastructure provided by GPS technology. Parcel and topographical data are also supplied to provide a map that can be used to identify locations of drainage ways and outfalls within the City of Conover. Our GIS Mapping is also linked to our citywide work order system, which gives us the ability to schedule and track activities needed and performed along the system. 13 As a provision of our Regional GIS Consortium arrangement, the county updates the GIS base mapping layers. The Map is to be kept current through coordination of the Public Works Department and GIS Department. Stormwater mapping will be available on the City computer network. Conover Staff members will provide hard copy maps upon request and a copy will be available for Public inspection at the Public Works Facility located at 939 4`h Street Southwest. 7.3.3. Regulatory Mechanism The regulatory mechanism used will be the Phase II Stormwater Ordinance and the City's Code of Ordinances. Key components of the Phase Ii Stormwater Ordinance are the right to inspect for illicit discharges on private property and the requirement for the elimination at the source of any illicit discharges that are discovered. 7.3.4. Enforcement Actions The enforcement of the illicit discharge section of the Phase II Stormwater Ordinance will be the responsibility of the City's Code Enforcement Division of the Planning Department. Primarily, the Phase II Stormwater Ordinance prohibits illicit discharges into the MS4. The ordinance also establishes the right to inspect for illicit discharges on, private property. The requirement for the elimination of illicit discharges at the source is also established by the ordinance. Illicit discharges are considered a public nuisance per the City's adopted Phase II Ordinance and shall be abated in accordance with the procedures set forth in Chapter 12-Health and Sanitation Nuisances of the Conover Code of Ordinances. 7.3.5. Detection and Elimination The City will develop a plan to detect and address illicit (non -storm water) discharges including illegal dumping into the system (MS4). The plan will be designed to meet the following criteria: • Locate problem areas - Methods may include public complaint, visual inspections and sampling, inspection by public works personnel • Find the source - Methods may include dye test / smoke test, upstream tracing or septic system and commercial / industrial building inspections. • Remove / Correct Illicit Connections - Once the source is identified, the offending discharger will be notified to correct the problem. Working with and educating first offenders will be a common course of action when applicable. • Documentation of actions - Documentation will be performed to illustrate that progress is being made to eliminate illicit connections and discharges. Information may include number of outfalls screened, complaints screened and corrected, number of discharges detected and / or eliminated and number / type of tests performed. • Field personnel will receive periodic training on how to identify illicit discharges to the MS4, and if necessary, track them to locate the source of the illicit discharge. When dry weather flows are discovered, the field personnel may report the dry weather flows so that they can be investigated by Code Enforcement. 14 7.3.6. Non-Stormwater Discharges 1.

Occasional Incidental Non-Stormwater Discharges None identified. 7.3.8. Outreach The outreach program is based upon reaching the majority of the general public and the various businesses that operate within the City limits. The public education and outreach program, the public involvement and participation program, and the pollution prevention and good housekeeping program will all be part of a coordinated effort. Informing the general public, various businesses, and municipal employees of the importance of the hazards associated with illicit discharges and improper disposal of waste will be an integral part of all three of these minimum measures. The strategies used in the public education and public involvement minimum measures will be supplemented by employee training and other aspects of the good housekeeping minimum measure. 7.3.9. Decision Process The approach being utilized takes into consideration existing programs that can be tailored to also address the Storm water need. Using Staff currently involved in inspection of wastewater sewers and performing the GPS of new infrastructure will broaden our Staff awareness and involvement in stormwater activities, BMPs and Goals were considered based upon our ability to initiate and gain benefit from those actions. 7.3.10. Evaluation The measurable goals and BMPs reflect the needs and characteristics of the City and its system, such measures will gauge permit compliance and more importantly program effectiveness. The measurable goals and BMPs that address requirements and intent of the control measure are shown in the SMP Table. 15 This facet of the program will be coordinated and performed by Conover Staff, City Attorney, and City Council. Staff members responsible include; Street Supervisor - Keith Crafton, Environmental Coordinator - Terry Lail, and Public Works Director - Jimmy Clark. 7.4 Construction Site Stormwater Runoff 7.4.1 BMP Summary Table BMP Measurable Goals Yr 1 Yr 2 Yr 3 Yr 4 Yr 5 Responsible Position The City will require that a copy of the approval letter from Catawba County Utilities and Engineering Department, Erosion Control Division be submitted before building or grading Erosion and Sediment project will be Planning Control Plan approved if the X X X X X Department project will disturb an acre of more of land. Projects of less than an acre are required to complete a City of Conover Sediment and Erosion Control Permit 7.4.2. Regulatory Mechanism The regulatory mechanism used will be the Catawba County Utilities and Engineering Department, Erosion and Sedimentation Control Division's local erosion and sediment control program delegated by NCDENR, Division of Land Resources. The City will rely on the Catawba County to enforce the provisions of the NPDES Phase II Construction Site Runoff Controls minimum measure within the City limits and ETi- The City will require that a copy of the erosion control approval letter from Catawba County be submitted before building or grading permits will be issued if construction activities will result in a land disturbance of an acre or more. The City also requires projects of less than one acre to conditions outlined in a sedimentation and erosion control application. These sites are monitored by City staff as construction takes place to ensure that sediment is not leaving the site. 16 7.5 Post Construction Stormwater Management in New Development and Redevelopment 7,5.1, EMP Summary Table HMP Measurable Goals Yr Yr Yr Yr Yr Responsible Position 1 2 3 4 5 The City will require that all new or redevelopment projects that meet the criteria Post Construction specified in the 1 Stormwater Controls NPDES Phase II X X X X X Planning Department permit employ engineered stormwater controls.

The City will require recorded 0&M agreements and posting of Post Construction financial assurance 2 Operation and for the purpose of X X X X X Planning Department maintenance Maintenance necessary for designed performance of stormwater control structures. The City will On site wastewater coordinate Environmental 3 treatment /septic oversight for these X X X X Coordinator/Public systems with the systems Catawba County Works Health Department 17 7.5.2. Non -Structural BMP's The City will promote Prevention Measures (non-structural BMPs) as our first line of defense against runoff problems. Proper planning and zoning, which guides high impact growth away from sensitive areas, will be considered to protect water quality. Site based controls that include buffer strips; riparian zone preservation and designation of open space are also common practices that will be used. The preservation of open space and natural features is encouraged throughout the code, Intensity, dimensional, and design standards contain provisions to encourage landscaping and tree plantings. The application of these provisions ranges from residential subdivisions to perimeter buffers and screenings to interior parking lot landscaping. There are also provisions to set aside areas for recreation and open space. Special purpose districts are also used to comply with the watershed and buffer regulations. All of these provisions combined have the effect of reducing impervious surface area. 7.5.3. Structural BMP's Engineered Stormwater BMPs are currently required by the City of Conover's Phase II Stormwater Ordinance which is in effect for the entire City and ETJ, as well as the Conover Zoning Ordinance portion in the Watershed Protection Overlay District (Water Supply Watershed). The Storm Water Best Management Practices Manual published by the NCDENR, DWQ is used as a guideline for the requirements for all engineered stormwater BMPs. The more restrictive provisions of the various regulations govern where they overlap. 7.5.4 Regulatory Mechanism The regulatory mechanism used will be the City's Code of Ordinances. The Phase II Stormwater Ordinance and the City of Conover's Zoning Ordinance both apply to all development, public and private, within the City and its ETJ. Both the Phase II Stormwater Ordinance and the Zoning Ordinance address the requirements for post -construction Stormwater controls. 7.5.5 Operation and Maintenance The long-term operation and maintenance of the stormwater control structure BMPs will be assured by operation and maintenance agreements recorded with the Catawba County Register of Deeds. The financial security of the agreement will be assured by the posting of adequate financial instruments for the purpose of the maintenance, repairs, or reconstruction necessary for adequate performance of the storm- water control structures. An operation and maintenance plan shall be provided that is consistent with the recorded operation and maintenance agreement. Annual inspections of the Stormwater controls must be conducted by a qualified professional. A copy of the annual inspection report must be furnished to the City's Planning Department. The City will coordinate oversight for on -site wastewater treatment systems with the Catawba County Environmental Health Department. 7.5.6. Decision Process The City's plan of action includes measures that utilize City / State requirements for site runoff controls. The first step in the decision process was to compare all of the current stormwater regulations that apply within the City limits and ETJ. These various regulations were reviewed to determine which 18 provisions are more restrictive, so that the more restrictive regulations can be applied where they overlap. The individual BMPs, measurable goals, and the responsible persons/positions are listed in the BMP summary table for this minimum measure. 7.5.7. Measurable Goals The measurable goals and BMPs reflect the needs and characteristics of the City and its system. The measurable goals and BMPs that address requirements and intent of the control measure are shown in the BMP Table. This facet of the program will be coordinated and performed by City Staff members as designated in the table. 7.6 Pollution Prevention/Good Housekeeping for Municipal Operations 7.6.1.

The Northeast Wastewater Treatment Plant is subject to NPDES General Permit NCGlIO000 (COC NCG110145). 7.6.3. Training The City of Conover will conduct training to educate all employees on clean water issues and on workplace responsibilities to reduce or eliminate pollutants from stormwater. 7.6.4. Maintenance and Inspections Facilities will be inspected annually, results documented, deficiencies noted and corrected as soon as possible by Public Works staff. 7.6.5. Vehicular Operations Vehicular operations contribute pollutants that are commonly removed from municipal parking lots and streets by sweeping operations. Vehicle maintenance activities typically take place indoors. The majority of municipal vehicles and equipment parked overnight at the public services complex have covered parking/storage areas. Since this is the same complex where vehicle maintenance operations take place, the covered storage and maintenance areas reduce the pollutants discharged into the storm drainage system. Vehicle fluids are normally removed from paved areas using compounds that absorb the fluids. Periodically, additional measures will be evaluated to reduce the discharge of pollutants from these areas. 7.6.6. Waste Disposal Waste is discarded at the County operated Public Landfill, Used motor oil is recycled and used as fuel for heating the maintenance garage. 7.6.7. Flood Management Projects Flood management projects are non -typical for this area. Regional detention facilities to control flooding have not been necessary. Stormwater management concentrates on BMPs for water quality and the controlled release of stormwater discharges from new development. The storm Water Best Management Practices Manual published by the NCDENR, DWQ is used as a guideline for the design review of stormwater BMPs. 7.6.6. Existing Ordinance A review of existing ordinances, in conjunction with the other minimum measures, has been performed to ensure compliance with Phase II stormwater regulations. 20 7.6.9. Decision Process Every effort is being made to remove outside storage of materials that potentially could contaminate storm water runoff within the site. Wash down efforts are confined to areas accommodated by sanitary sewer service. Spill prevention Plans are also being revised where needed and employees trained to address emergency and non -emergency situations. 7.6.10. Evaluation The measurable goals and BMPs reflect the needs and characteristics of the City and its system. The measurable goals and BMPs that address requirements and intent of the control measure are shown in the BMP Table. This facet of the program will be coordinated and performed by City Staff members, Street Supervisor - Keith Crafton, Fleet Supervisor - Ron Brown, and Public Works Director - Jimmy Clark. 21 State of North Carolina OFFIC USE ONLY Department of Environment & Natural Resources Date Rec`d Division of Water Quality Fee Paid Permit Number NPDES STORMWATER PERMIT APPLICATION FORM This application form is for use by public bodies seeking NPDES stormwater permit coverage for Regulated Public Entities (RPE) pursuant to Title 15A North Carolina Administrative Code 2H .0126.

Storm Sewer System Information 1.1 Population: -Permanent: 6604 -Basis of Population statistic: 2000 Census -Seasonal: -Method used to create seasonal estimates: 1.2 Growth Rate: 2.2 1,3 Jurisdictional Area: 14.8 square miles (City Limits + ETJ) MS4 Service Area: Same 1.4 MS4 Conveyance System The' City of Conover storm water system includes drainage infrastructure such as inlets, basins, manholes, pipes, culverts, bridges, ditches, and swales. These structures contain and move storm water that naturally gravitates to privately owned storm water systems and receiving streams of the State. The City has (10) ten receiving streams throughout our area that direct waters to the Catawba River Basin. Open channels make up the majority of the City and Privately owned systems throughout Conover. City Crews provide maintenance to the City System by the following methods: • open Channel / Ditch -line Maintenance - operation includes cleaning, clearing and restoration of open ditch -lines within the City right of ways. Providing riprap stabilization and seed/grass measures are commonly used to correct, minimize and control erosion issues in these areas. • Drainage Pipe Maintenance - City Staff provides pipe installation for property owners desiring to pipe areas within the public right of ways. Other related work may include; catch -basin construction, catch -basin and pipe cleaning, catch -basin and pipe repair, erosion control measures and spill hazard response. • Sweeping - The City provides curb -sweeping service for removal of trash, litter and other debris. Additionally, they may respond to emergency situations possibly involving hazardous substances. • Flushing - The City provides flushing service to the downtown curbed streets and other areas on an as needed basis. Litter / Dead Animal Collection - This activity includes the removal of trash, debris and dead animals from City maintained streets, parking lots and walkways. • Leaf Collection - The City has (2) two options for leaf collection services for it's residents. Citizens may bag their leaves in clear bags or rake loose leaves to the curb or ditch -line boundaries to receive vacuum service. Residents are asked to keep ditch -lines free of leaves at all times. The city employs (3) Full -Time positions for system maintenance. The system is inspected yearly for maintenance problems and cleaned following rain events. 3 1.5 Land Use Composition Estimates Residential: 53.13 % Commercial: 13.48 % Industrial: 31-10 % Open Space: 1.69 % Total: 100% 1.6 Estimate Methodology Land Use Percentages were calculated based on the zoning information maintained by the Planning and GIS Departments. By grouping the various zoning districts within the City of Conover into 4 main categories, using Arcinfo software and calculating the total area of each category, percentages were calculated by dividing each category by the total area of Conover. 1.7 TMDL Identification NONE 2.

Existing Water Quality Pro rams 3.1 Local Programs The City of Conover currently implements a local water quality program that includes a Water Supply Watershed Protection Program, a delegated Erosion and Sediment Control. and Land Use Plan. The City has developed a Water Supply Watershed Protection District (WSP District) and incorporated its definition and requirements into the Code of Ordinances. The purpose of the district is to regulate the development and land use density in order to limit water supply 4 watershed exposure to non -point source discharge and pollution. This effort is a proactive approach, rather than a reactive, to assure a clean, safe and healthy water supply. The City has delegated Erosion and Sediment Control by requiring development over 1 acre to present evidence that a sediment control plan has been submitted to and results received from the North Carolina Department of Natural and Economic Resources, Land Quality Section. The City of Conover Planning Department has created and maintains a Land Use Plan that regulates land use throughout the city, through the use of various zoning districts and guides high impact growth away from sensitive areas. 3.2 State Programs NCDENR Erosion and Sediment Control 4.

Report annually on data collected and issues addressed. 6 Stormwater Drain Continue program, with the X X X X X Assistant Planner Stenciling help of the Boy Scouts, stenciling stormwater drains to make the public aware of the outflow of storm water. 7.1.2. Target Audience The City of Conover will target all members of the community with respect to Public Education. Households, farmers, businesses and industry, gas station owners and gardeners are just a few of the citizen groups targeted. Every member of the community has been targeted for education, because only with citizen participation, can we reduce or remove pollution from the stormwater system. 1.1.3 Target Pollutant Sources Specific pollutants being targeted by Conover's program include, soils & silts, trash, bacteria, yard waste and grease / oils that may intentionally or inadvertently be discharged into the system. These pollutants are common among storm water systems located within Urban and Suburban areas and are impacted by construction site development. Such pollutants may be reduced or eliminated by following proper principles in the disposal, transportation, use and containment of the components. 7.1.4 Outreach Program For (3) three years Conover has provided Public Education through these efforts: • Storm Water Drain Stenciling (with Boy Scouts) • Development and distribution of Educational handouts to residents • Display of posters and Storm water information at two City functions. Public Works Day (May) and Community Workshop (March) We plan to continue those practices and expand efforts by the utilization of our web site, offering additional educational programs to local schools / civic organizations and working with developers and Contractors to develop and implement procedures to address construction run-off. 7.1.5 Decision Process The City of Conover feels that the practices currently used and those proposed blend well with our Community efforts to keep the public informed on all issues. Efforts such as these have been very successful for our community. Expanding on current practices will help keep the cost of the program down for our residents. Public Education for developmental/construction run-off will be targeted as program goal. 7.1.5 Evaluation The Public Education Program will be evaluated every year by referencing the suggested BMP's and reporting any activity in the annual report to the State. By tracking the number of publications produced, and comparing the amount of information provided to the public through mailers, brochures and web hits, a count of citizens reached can be calculated. A written record of calls to the hotline created will also provide a quantifiable number of citizens educated in proper stormwater management. c) 7.2 Public Involvement and Participation 7.2.1 BMP Summary Table BMP Measurable Goals Yr 1 Yr 2 Yr 3 Yr 4 Yr 5 Responsible Party/Position 1 Storm Water Incorporate Storm Water X X X X X Public Works Educational educational meetings into the Meetings local Community Watch programs.

Report activity in annual report. 4 "Adopt a Storm Develop and implement a X X Public Works Drain" program program in which individuals and groups would assist the City in keeping drains free of debris and assist in monitoring private waterways. Report activity in annual report 7.2.2 Target Audience The City of Conover will again target all members of the community with respect to Public Involvement. Homeowner associations, neighborhood groups, and local businesses and .industries are just a few of the groups targeted. Every member of the community has been targeted for involvement, because only with citizen participation, can we reduce or remove pollution from the stormwater system. 7.2.3 Participation Program During six City held informational functions Staff supplied information regarding Storm Water and the six program components. Comments were made most commonly regarding types of contamination, sources of contamination and possible financial impacts to citizens. A Public Hearing was also held on March 3Id, 2003 to receive citizen comments regarding the application phase of the project. During program development we will continue to promote public involvement and utilize public comments as a component of our strategy. H 7.2.4. Decision Process The City of Conover is going to develop the public involvement and participation program using several of the BMP's suggested. We plan to incorporate Storm Water educational meetings into the local Community Watch Programs and provide basic information, brochures and hot line number to residents. We plan to utilize the stenciling program to involve students, parents and residents in Storm Water activities and provide this activity in each area of the City and seek involvement by public notices. We plan to form voluntary Neighborhood Clean-up Groups and target 50% participation. And finally plan to develop and implement a "Adopt a Storm Drain" program for the City encouraging individuals and groups to keep drains free of debris and assist in monitoring private waterways. This facet of the program will be coordinated and performed by City Staff members, Street Supervisor - Keith Crafton and Public Works Director - Jimmy Clark. 7.2.5 Evaluation The success of this measure will be evaluated by reporting annually to the state the number of meetings held, stormdrains stenciled, Neighborhood clean up groups established and storm drains adopted on a year-to-year basis. 7.3 Illicit Discharge and Elimination 7.3.1.

Storm Sewer Map The City has begun the development of a storm sewer system map identifying the system outfalls, City infrastructure/system, Private system and State system. Elements shown include catch basins, curb inlets, pipes, culverts, swales and ditches that collect water and eventually discharge into local streams and surface waters. The map is comprised of a digital GIS base map with infrastructure provided by GPS technology_ Parcel and topographical data are also supplied to provide a map that can be used to identify locations of drainage ways and outfalls within the City of Conover. The Map is to be kept current by using (in house) GPS equipment to capture new infrastructure points and provide a database of each point for use in maintenance and inspection practices. Our GIS Mapping is also linked to our citywide work order system, which give us the ability to schedule and track activities needed and performed along the system. As a provision of our Regional GIS Consortium arrangement, the county updates quarterly the GIS base mapping layers. The Map is to be kept current through coordination of the Public Works Department and GIS Department. Storm -water mapping will be available on the City computer network. Conover Staff members will provide hard copy maps upon request and a copy will be available for Public inspection at the Public Works Facility located at 939 4`h Street Southwest. 7.3.3, Regulatory Mechanism The City does have regulations in our Code of Ordinances (Chapter 12 - Nuisances and Chapter 11 - Garbage, Trash and Weeds) that prohibits the disposal of any solid waste, trash, tree limbs or other material that may contaminate or block the drainage way. An ordinance meeting the following objectives will be developed, adopted and implemented by the City of Conover. • To regulate the contribution of pollutants to the municipal separate storm sewer (MS4) by storm water discharges by any user. • To prohibit Illicit Connections and Discharges to the municipal separate storm sewer system. • To establish legal authority to carry out all inspection, surveillance and monitoring procedures necessary to ensure compliance with this ordinance. The ordinance proposed will comply with requirements of the National Pollutant Discharge Elimination System (NPDES) permit process. 7.3.4. EnforcemenC Actions The proposed ordinance will also identify the appropriate enforcement actions to be taken whenever illicit connections are discovered. Such enforcement shall consider the severity of the action and negative impacts to the water body or watercourse. Notice of Violations may include; • Monitoring, analysis and reporting • Elimination of discharges / connections • Abatement or remediation of pollution or contamination • Payment of fine or remediation cost • Implementation of control measures and / or BMPs 13 7.3.5. Detection and Elimination The City will develop a plan to detect and address illicit (non- storm water) discharges including illegal dumping into the system (MS4). The plan will be designed to meet the following criteria. • Locate problem areas - Methods may include public complaint, visual inspections and sampling • Find the source - Methods may include dye test / smoke test, upstream tracing or septic system and commercial / industrial building inspections. • Remove / Correct Illicit Connections - Once the source is identified, the offending discharger will be notified to correct the problem. Working with and educating first offenders will be a common course of action when applicable. • Documentation of actions - Documentation will be performed to illustrate that progress is being made to eliminate illicit connections and discharges. Information may include number of outfalls screened, complaints screened and corrected, number of discharges detected and / or eliminated and number / type of tests performed. 7.3.6.

Outreach 535.2005(20)) City of Conover Staff is involved in both the Public Education and outreach efforts now and as proposed in sections 10 & 11. Those efforts will include educational information regarding ways to detect and eliminate illicit discharges. The efforts will include initiating a volunteer recycling program for oil and promoting the use of the County's household hazardous waste program. 14 7.3.9. Decision Process The approach being utilized takes into consideration existing programs that can be tailored to also address the Storm water need. Using Staff currently involved in inspection of wastewater sewers and performing the GPS of new infrastructure will broaden our Staff awareness and involvement in Storm Water activities. BMPs and Goals were considered based upon our ability to initiate and gain benefit from those actions. 7.3.10. Evaluation The measurable goals and BMPs reflect the needs and characteristics of the City and its system, such measures will gauge permit compliance and more importantly program effectiveness. The measurable goals and BMPs that address requirements and intent of the control measure are shown in the BMP Table. This facet of the program will be coordinated and performed by Conover Staff, City Attorney, and City Council. Staff members responsible include; Street Supervisor - Keith Crafton, ASst. Planner - Chris Niver and Public Works Director - Jimmy Clark. 15 7.4 Construction Site Stormwater Runoff 7.4.1 BMP Summary Table BMP Measurable Goals Yr 1 Yr 2 Yr 3 Yr 4 Yr 51 Responsible Position Development and implementation of the Stormwater Management Develop the organizational Plan which will include 1 plan, including enforcement requirements for X X X X X Public Works and inspection strategies to managing construction manage construction sites. site runoff.

Regulatory Mechanism The City of Conover proposes to use the State Program to comply with this Storm Water Phase II minimum measure. Use of this program will provide these basic control objectives that will protect public and private properties from damage by land disturbing activities. • Identify Critical Areas • Limit Exposed Areas • Limit Time of Exposure • Control Surface Water • Control Sedimentation • Manage Storm Water Runoff By meeting these objectives, pollutants commonly discharged from construction sites will also be reduced. City Contact Person: Jimmy A. Clark City of Conover - Public Works Dir. State Contact Person: Steve Allred NC - DEM Mooresville Regional Office Methods approved and recommended by the State DEM will be used to control sediment and erosion within our Community. Commonly used controls such as Vegetative Practices. Detention / Retention Practices and Infiltration Devices will be recommended for use by persons involved in land disturbing activities. 7.4.3. Plan Review The City currently has a Site Plan Review procedure that is required for new and redevelopment activities. The current procedure does not require controls nor enforce regulations currently imposed by The State. Staff is currently receiving and reviewing (24) Site Plans per year from area Developers. Measures imposed to reduce amounts of storm water and pollutants will include. • Land Use Planning Strategies • Retention of vegetated natural buffers • Construction of Detention / Retention Basins • Check Dam Construction • Erosion Barriers • And other BMPs that that have a positive impact on water quality Such procedures will be developed and implemented to coincide with our existing Site Plan Review Process and State Sedimentation Control Requirements as major program element. 7.4.4. Enforcement. Enforcement actions will be developed to address Storm Water related issues. Such actions will be consistent with existing code enforcement actions taken by the City. Those actions are consistent with North Carolina General Statutes that govern Local Governments. 17 7.4.5. Inspections City Staff currently inspects new and redevelopment sites that involve new public utilities and roadways. This practice will be broadened to include the inspection of Construction Site Runoff Controls. Such inspections will ensure that the proper BMPs are in place, properly installed, properly maintained and performing as intended. All such inspections will be recorded and kept with project files to document project compliance or non-compliance with the State and City requirements. During inspections, staff will work with developers by providing additional guidance, educational assistance, issuing warnings for corrective actions and accessing penalties if appropriate. The City will advise the Regional DEM of non -conformances to regulation where applicable. 7.4.6. Public Information As referenced in the public education section of the permit, the City gains public comment in many forms both currently and proposed. The information gained will be used to assist with tracking problem areas and maintaining enforcement. Such involvement is crucial to the success of the program to meet established goals. 7.4.7. Decision Process Although the program piggy backs State erosion and sedimentation control procedures, we have proposed in house measures to accent that program and provide additional actions to control construction activities. With both agencies working toward compliance with the requirements and procedures we can collectively meet program goals and objectives. 7.4.8 Evaluation The measurable goals and BMPs reflect the needs and characteristics of the City and its system. The measurable goals and BMPs that address requirements and intent of the control measure are shown in the BMP Table. This facet of the program will be coordinated and performed by City Staff members, Street Supervisor - Keith Crafton and Public Works Director - Jimmy Clark. 7.5 Post Construction Stormwater Management in New Development and Redevelopment 7.5..1. City of Conover's existing development policy requires site drainage to be addressed as a part of the development plan. Practices are consistent with State policy and practices. Post construction control measures will be designed and implemented considering site characteristics, developmental use and established removal rates. Measures will be consistent guidelines established by NCDENR as published in the April 1999 manual. V 7.5.8.

Non -Structural BMP's The City will promote Prevention Measures (non-structural BMPs) as our first line of defense against runoff problems. Proper planning and zoning, which guides high impact growth away from sensitive areas, will be considered to protect water quality. Site based controls that include buffer strips, riparian zone preservation and designation of open space are also common practices that will be used. 7.5.10. Structural BMP's Sites requiring additional protection will be required to use Control Measures (structural BMPs) to address runoff negative impacts. Those BMPs may include the following: Storage and Detention Controls - These practices will both control storm water volume and settle out particulates for pollutant removal. Infiltration Practices - These practices may include basins, trenches, dry wells and porous pavements that are designed to facilitate the percolation of runoff through the soil to the groundwater. Vegetative Practices - These practices include grassy swales, filter strips, rain gardens and artificial wetlands that will enhance pollutant removal. 7.5- 1 Regulatory Mechanism The Storm Water ordinance will provide the regulatory mechanism to address post construction runoff controls. 7.5.12 Operation and Maintenance The ordinance will require long-term maintenance to be provided by the site Developer / Owner as a condition to the developmental permit. Established regulatory provisions within the ordinance will also regulate this condition. New sub division development, which requires contractual arrangements for open space, will be required to designate permanent maintenance responsibility to either the primary Developer, property owner or representative association. Such designation will be a condition to the Developmental contract. 7.5.13. Decision Process The City's plan of action includes measures that utilizes City / State requirements for site runoff controls. Those controls are to be incorporated / modified as permanent measures where possible and feasible. Non-structural measures will be our first approach when reviewing new developmental plans. Priority areas include large commercial and industrial sites with potential for substantial negative impacts. 7.5.14. Measurable Goals The measurable goals and BMPs reflect the needs and characteristics of the City and its system. The measurable goals and BMPs that address requirements and intent of the control measure are shown in the BMP Table. This facet of the program will be coordinated and performed by City Staff members, Street Supervisor - Keith Crafton and Public works Director - Jimmy Clark. pill 7.6 Pollution Prevention/Good Housekeeping for Municipal Operations 7.6.1.

Training The City of Conover will develop a training program to educate all employees on clean water issues and on workplace responsibilities to reduce or eliminate pollutants from stormwater. 7.6.4. Maintenance and Inspections The plan being developed for the NPDES facility will outline maintenance measures and define responsibilities to carry out those measures as required by the Phase II rule. City Staff properly trained and familiar with Storm Water requirements and goals will perform such procedures. 7.6.5. Vehicular Operations The Facility Plan will include additional measures to reduce or eliminate the possible pollutant runoff from the facility grounds. Measures may include: confinement walls, retention barriers, infiltration trenches and settling basins where applicable. 7.6.6. waste Disposal waste is discarded at the County operated Public Landfill 7.6.7. Flood Management Projects We propose to coordinate with Local Flood Control Managers to identify and address environmental impacts from such projects. 7.6.8. Existing Ordinance 7.6.9. Other Evaluations 7.6.10. Decision Process In developing this Facility Plan every effort is being made to remove outside storage of materials that potentially could contaminate storm water runoff within the site. Wash down efforts are being confined to areas accommodated by sanitary sewer service. Spill prevention Plans are also being revised where needed and employees trained to address emergency and non - emergency situations. 7,6.11. Evaluation The measurable goals and BMPs reflect the needs and characteristics of the City and its system. The measurable goals and BMPs that address requirements and intent of the control measure are shown in the BMP Table.
