Morganton is located within the Catawba River Basin. The Catawba River is used as a source of drinking water for the City and many jurisdictions downstream. 1.1 Population The population of the City of Morganton is 17,194 according to the 2008 Population estimates by the NC Office of Demographics. The City is unable to determine the exact populations of the Extra Territorial Jurisdiction (ETJ) because census tracts/bocks do not in any way correspond with the ETJ boundaries. City staff has worked with Burke County GIS personnel in an attempt to determine the population of the ETJ. Based on these estimates it appears that approximately 500 people per square mile live within the ETJ. The area of the Morganton ETJ is 19.51 square miles, which would yield a population of 9,755 people. This figure combined with the City population of 17,194 yields a total population of 26,949 for both the City of Morganton and the ETJ. 1.2 Growth Rate According to figures from the Bureau of Census, the 2000 population of the City of Morganton was 17,310. As previously stated, the 2008 NC estimates shows Morganton to have a population of 17,194. Based on these two figures, Morganton has experienced a negative growth rate of -0.7% between 2000 and 2008 for an annualized growth rate of -0.01 %. 1.3 Jurisdictional & MS Forest Service Area The City of Morganton encompasses an area of 18.85 square miles. The Extra territorial Jurisdictional (ETJ) area contains 19.51 square miles. 1.4 MS4 Conveyance System The City of Morganton maintains 87.42 miles of streets within our corporate boundaries. 46.52 miles of these streets are curb and guttered and 40.90 miles are not curb and guttered. The curb and guttered streets conveys storm water by the run-off following gutter lines to catch basins at which point the water is taken into piping systems which range from 15" to 4 8 " in size. The water is then conveyed to open ditches or streams before it is discharged. The storm water conveyance system along non -curb and guttered streets consists of ditch lines, grassed and rip -rapped swells to the point at which the water passes under streets and through pipes which discharge into ditches or streams. Pipes range in size from 15" to 96". The City, as a general rule, assumes no responsibility for maintenance, inspection, or improvements on private property. Storm water maintenance and inspection activities outside the rights -of -way are the responsibility of private owners. 2 Maintenance activities within rights -of -way are normally performed on an as -needed basis by the Public Works Department. The majority of the storm drainage system maintenance is in response to calls from property owners. The remainder of the storm drainage system maintenance work is in response to needs detected by the Public Works Department. These typically include removal of trash and debris and flow impediments. Crews that perform this maintenance work also perform other duties. 1.5 Land Use Composition Estimates The City of Morganton has six residential type zones, which are combined below as residential. The City of Morganton has four commercial type zones, which are combined as commercial. The City has two industrial type zones, which are combined as industrial. Open space will be considered those parcels of land that are owned and controlled by the City of Morganton and used for recreational purposes. City and ETJ Residential 72% Commercial 14% Industrial 12% Open Space 2% 1.6 Estimate Methodology The city staff worked with the GIS staff with the Western Piedmont Council of Governments concerning all of the above percentages except open space. City staff determined open space acreage owned by the City of Morganton, which was slightly over 550 acres and that was converted to square miles and divided by the number of square miles within the City, which yielded a 2% open space. The County GIS staff was able to determine the area of each zoning within the City and within the ETJ. 1.7 TMDL Identification A review of the Draft 2008 303(d) list of streams with a total maximum daily load (TMDL) limits shows that there are no streams with the City of Morganton or the ETJ with that designation.

The remaining 5% of land area is within the Phase 2 Storm Water Protection Area. A portion of the WS-4 land area lies within one half a mile of the full pond elevation of Lake Rhodhiss and another portion lies within one half mile of the raw water intake of the City of Morganton. Both of these areas along the Catawba River are considered and classified as Critical Areas (CA) by the NCDENR Water Quality Division. The City of Morganton adopted a Water Supply Watershed Protection Ordinance in 1995. This Ordinance implements the Watershed Protection program to the requirements of the NCDENR. The City adopted a Phase 2 Storm Water Ordinance in 2007. This Ordinance implements the Phase 2 Storm Water Protection Program to the requirements of NCDENR. The City of Morganton follows North Carolina rules for building permit issuance on any land disturbing activities greater than one acre. The City requires developers to obtain an 4 approved Sedimentation and Erosion Control Permit from the Land Quality Section of the NCDENR prior to building permit issuance The City of Morganton has a Land Development Plan that provides a guide for development and Land Use Regulation within the City of Morganton and its surrounding jurisdiction. The City of Morganton has purchased or received by donation land along the Catawba River, Fiddlers Run Creek, Warriors Fork Creek, and Hunting Creek to develop recreational greenways. To date, the City has preserved approximately five miles of Catawba River Front property within the corporate limits, approximately 1.5 miles of Warrior Fork Creek Front, and approximately 1.5 miles of Fiddlers Run Creek. This program is a two -fold program that not only provides walking and biking trails to the community, but it also to protects a significant portion of land along the river and its tributaries from development and preserves a natural buffer between development and the river. 3.2 State Programs The North Carolina Environmental Management Commission (EMC) has adopted permanent buffer rules for the Catawba River and the lakes along the run of the river from the headwaters of Lake James to the SC state line. These rules became permanent in August of 2004. The Sedimentation and Pollution Control Act is administered by the Land Quality Section of NCDENR which requires any developer disturbing more than one acre of land to provide a sedimentation and erosion control plan. 4.0 Permitting Information 4.1 Responsible Party The responsible party for each measurable goal will be assigned by the Director of Development & Design Services, Mr. Lee E Anderson Please contact him using the information listed below: Mr. Lee E.

Mayor/City Council City Manager Director of Development & Design Services City Engineer Assistant City Engineer 4.3 Signing Official The application and permit will be signed by the City Manager of the City of Morganton. The Charter at the City of Morganton states in: Chapter 2 section 4-12: "The city manager shall be the chief executive officer of the City Government He shall be responsible to the City Council for the proper and efficient administration of City Government. " Chapter 2 section 4-13: "The City Manager shall see that the laws of the state and the ordinances resolutions, rules and regulations of the City are faithfully executed and enforced. " 5.0 Co -Permitting Information (if applicable) 5.1 Co-Permittees The City of Morganton has chosen not to enter into any agreements or contracts as a co- permittee to develop or implement any Phase II Storm Water Programs. 6.0 Reliance on Other Government Entity 6.1 Name of Entity The City will not develop, implement, or enforce a separate program for erosion and sedimentation Control since the NC DENR currently has rules and regulations in place to administer the NC Sedimentation and Pollution Control Act. The City will rely on the Land Quality section of NC DENR for enforcement of these rules subject to the one -acre land disturbance threshold. n 6.2 Element to be Implemented Sedimentation and Erosion Control: The City will rely on the Land Quality of NCDENR to enforce the provisions of the NPDES Phase II Construction Site Runoff Controls minimum measure and the State General Construction Storm Water Permit within the limits of the City and the ETJ. 6.3 Contact Information Mr. Janet Boyer, P.E. NCDENR Land Quality Division 2090 U.S. Highway 70, Swannanoa, NC 28778 828.296.4500 Asheville, NC 28801(828) 251-6208 6.4 Legal Agreement A legal agreement is unnecessary since current state law and administrative rules give NCDENR the authority for Sedimentation and Erosion Control enforcement. 7 7.0 Storm water Management Program Introduction and Overview The development and implementation of the storm water management program will first focus on existing city maintenance, programs and ordinances. The continuation of these programs, along with the development of new programs where necessary, is deemed the most effective approach to storm water management. The six major components of the storm water management program are the six minimum control measures required by NPDES Phase II. Municipal industrial activities will be included by the submission of Notice of Intent (NOI) for individual coverage for each location under the appropriate Storm Water General Permits of the State of North Carolina. 7.1 Public Education & Outreach On Storm water Impacts 7.1.1 BMP's and Measurable Goals for Public Education and Outreach ITEM BMP Measurable Goals Year Responsible 1 1 2 1 3 4-1 5 Position/Party �_ Use ut�hty billing to distnbute storm.water information , Distribute Iderature/brochures to to ttie public and place brochures �n public places to eneral ublic �z{{., ,>• dissemmate�lnfo[mation, .

Development & Design 7.1.2 The target audiences for the education program are the majority of the general public and the various businesses that operate within the limits of the City and the ETJ. Public awareness of the storm water program will be more effective using this strategy, because the general public includes for the most part the same individuals that operate and manage the various businesses. 7.1.3 The target pollutant sources are those normally associated with an increasingly urban area. Roads, parking lots, businesses, and residential development replaces the natural permeable landscape with more 8 impermeable surfaces. Storm water runoff increases and reaches streams more quickly. The number one pollutant is sediment. Chemicals deposited by vehicles, agricultural nutrient runoff and industrial activity also pollute storm water in the Morganton area. 7.1.4 The outreach program is again based upon reaching the majority of the general public and the various businesses that operate within the limits of the City and ETJ. Newspaper columns and utility bill inserts will reach the majority of the general public and businesses. Information on the City's website will reach a smaller audience, such as those with internet access at home or at work. Internet access is also available at the public libraries in the area. Public presentations will reach targeted citizen and business groups in smaller numbers. Educational materials will reach small groups of school students and to a lesser extent parents. All together, the program will reach the majority of the general public and businesses in the time period of the permit term. The strategies used for the various contact groups will vary. The City of Morganton will attempt to satisfy the public education and outreach requirements of the Phase II program by: a) Participating in a statewide education and outreach program by mailing any brochures or educational information developed by the NCDENR once a year within the City's typical billing process for public water, sewer, cable television, or electrical utilities. Currently the City mails 6000 cable bills per month inside the corporate limits and 11,000 bills per month for water, sewer, and electric service within the ETJ and beyond. b) Providing storm water education through a local COMPAS cable television access channel such as the VHS tape of the storm water program developed by NC State University entitled "Down the Drain" as often as needed up to 4 times a year. The City would also broadcast any other generic storm water related educational material that has been developed by the EPA, NCDENR or other agencies. c) The City of Morganton will provide visual information and discussion related to Phase II storm -water issues once every two (2) years. These programs could discuss such things as: proper disposal of cooking grease for restaurants, proper disposal of oil and automotive fluids by individuals or auto repair shops, proper parking lot sweeping techniques aimed at reducing the amount of automotive pollutants flushed from parking areas by rainfall, proper erosion control techniques to reduce sediment loss resulting from construction activities, recycling activities for common household waste products, and the proper disposal of yard waste. N 7.1.5 Morganton's first step in the decision process was to determine the main pollutants and sources associated with an expanding urban area so that a program could be designed to reach the majority of citizens. BMP's were considered based upon the likely success of reaching the most widespread audience of the general public. The rationale for this is discussed above in the details of the outreach program. Specific examples of targeted programs are also given above. The individual BMP's, measurable goals, and the responsible persons/positions are listed in the BMP summary table for this minimum measure. 7.2 Public Involvement & Participation Program 7.2.1 BMP's and Measurable Goals for Public Participation and Involvement Year Responsible ITEM BMP Measurable Goals 1 2 3 4 5 Position/Party 1+,` "� R'd4 S �IN'l- A � r,v:r:, , 4 '... �' _y, : J�` d - 7F ,�' f 5 -.� f F t 2 T �,(e o t 1,�fi; 3"h.%'P'2=�.F„��y''}'+�yF�{ "YyY l > w 1 S '�• � - y `3 ay'-•.y- 4As. ,k t Co dud public meetings as requ red in conJu ctio w & Si _ Development antl Design - Conduct Put hc:Meetin s.:.

This strategy will reach various ethic and economic groups within the community. 7.2.3 The participation program to date involves various City Departments, involved citizens and public committees have participated in the current storm water program by way of the existing Water Supply Watershed Rules, Phase 2 Storm Water Rules, and Catawba River Basin Buffer regulations. The current storm water programs are outlined in the City Code. The most restrictive of the current state regulation will have to be reflected in the revision of the City Code. The general public has been involved through public hearings and the development of current regulations. Many of these public hearings involved citizens from across the state, The development of this NPDES Phase II permit application was done primarily by the City's 10 Development and Design Services Department. A local Hunting Creek Advisory Group meets on a monthly basis for the purpose of developing a Watershed management Plan for the entire Hunting Creek basin. A Water Supply Watershed Review Committee meets on an as needed basis to discuss stormwater quality issues and provide program oversight. Future public meetings will be held in conjunction with City Council meetings to involve the public in the decision -making process concerning storm water program activities. Citizen and stakeholder groups will be requested to provide more focused input. Outreach programs for targeted organized groups will help reach a cross section of ethnic and economic groups within the City. The strategies used for the various groups will vary. For example, litter clean up, activities could be performed by organized groups dedicated to public service such as Adopt -A -Street . Some public service oriented companies may allow their employees to participate in these activities as well. Volunteers from professional and business groups could be utilized as speakers to other such groups in the community, such as the Agriculture Extension office. 7.2.4.The first step in our decision process was to determine how to involve not only the general public, but also the by various organized groups in the community. The various ethnic and economic groups also need to be reached in the process. When considering the various types of groups and organizations, trade associations, neighborhood associations, public service groups, and youth oriented groups. The rationale for this is discussed above in the participation program section. Specific examples of targeted programs that can be developed are also given above. The individual BMP's, measurable goals, and the responsible persons/positions are listed in the BMP summary table for this minimum measure. 7.2.5. Assigned specific persons/positions the responsibility and intermediate milestone dates will allow the tracking of progress against the overall BMP summary table timeline. Annual reports will contain the progress details and track it against the BMP summary timeline. The evaluation process for the measurable goals for this minimum measure therefore becomes a matter of determining if the necessary activities have been accomplished, based on the BMP summary table. 11 7.3 Illicit Discharge Detection and Elimination 7.3.1.

Pu6Uc,Works'Dlrector. 7.3.2. A map of the MS4 within the City and ETJ has been developed and incorporated into a City's County Geographic Information System (GIS). The GIS is a joint effort between the City of Morganton and the Western Piedmont Council of Governments. When the MS4 field survey information input was developed, the GIS data was collected showing any targeted outfalls, and the drainage basins that contributes to it, the MS4, and the types of residential, commercial, and industrial areas that might contribute any particular type of pollution to the outfall. The parcel boundaries, owner's name, most recent aerial photos, topographic features, and other information can also be immediately available as needed. Therefore, any particular type of working map that is needed for future field investigations will be generated using the GIS. The information in the GIS can be updated as necessary when new development or redevelopment occurs. Supplemental information such as the locations of detention ponds and other BMP's can also be tracked using the GIS. Other map sources such the Natural Resources conservation Service soil survey maps or the United States Geologic Survey quadrangle topographic maps may be used to delineate features such as perennial and intermittent surface waters. The names and locations of all receiving waters can also be verified using these maps. 7.3.3. The regulatory mechanism used will be the City's Code of Ordinances. A review of the local ordinances have been conducted to assure compliance with NCDENR standards. Any proposed modifications to prohibit illicit discharges into the MS4 will be drafted for review and approved by the Morganton City Council. Key components of the City's ordinance maintains the right to inspect for illicit discharges on private property, and the requirement for the elimination at the source of any illicit discharges that 12 are discovered. The ordinances and the field inspection program was developed within the first permit term period. Morganton's field inspection program takes place in conjunction with continued field surveys modifying existing mapping of the MS4. 7.3.4.The enforcement of illicit discharges are the responsibility of the City's Code Enforcement, Project Management, and Legal staff and other government entities also having responsibility for enforcement. Morganton's ordinance prohibits illicit discharges into the MS4. The ordinance establishes the right to inspect for illicit discharges on private property. The requirement for the elimination of illicit discharges at the source is also be established by the ordinance. The program for the detection and elimination of illicit discharges into the MS4 is addressed below. The enforcement procedures to ensure compliance with the ordinance will is also addressed below in the detection and elimination section. 7.3.5.Morganton's plan for detection and elimination of illicit discharges has three components starting with the initial mapping operation. Field inspections will were coordinated with the mapping operation and source identification and elimination constitutes the third phase of the plan. A field inspection program uses dry weather flow as the first indicator of a possible illicit discharge. Visual observations and initial field-testing for certain chemicals can be used to make the initial determination of whether the dry weather flow is in fact an illicit discharge. Further testing in a laboratory and the subsequent analysis can provide the confirmation of the initial field results, or determine that the dry weather flow is not an illicit discharge. After the source of the illicit discharge has been determined, several steps can be taken to ensure the enforcement of the ordinance and the elimination of the illicit discharge at the source. Steps, depending upon the nature of the source, can include: 1) Sending a letter to the property owner/business operator with a request for the owner/operator to investigate the source of the illicit discharge. 2) Conducting a site visit and interview to encourage the owner/operator to take voluntary corrective measures. 3) Performing additional tests if necessary to confirm the source of the illicit discharge. 4) Issuing a letter of noncompliance if the owner/operator does not take corrective action. 5) Sending a copy of the letter and information to the NCDENR requesting assistance. 6) Performing additional inspections as necessary to determine if corrective actions are taken. 7) Taking additional legal measures as necessary to see that corrective actions are taken. 13 The responsibility for the enforcement may be the NCDENR if, for example, the source is traced to an industrial facility that has an individual NPDES storm water discharge permit. An evaluation of land uses within the City and ETJ will be made to determine the initial areas where the MS4 is mapped and the initial field investigations for dry weather flows will take place. Land use information can be readily evaluated to determine the types of commercial, industrial, and residential areas that might contribute more pollution into the MS4. For example, older residential areas might have older sanitary sewer.lines or septic tanks that could contribute pollutants. Older industrial areas might have illicit floor drain connections to the MS4. Other industrial areas might have on -site treatment systems with illicit connections. Areas where vehicle maintenance activities are concentrated can also be targeted as potential pollution sources. The evaluations could also use the locations of sanitary sewer pretreatment programs as criteria. An inspection procedure was developed and provided to field. personnel during the initial mapping program. The inspection program provided initial investigation noting dry weather flow discovery in the MS4. When dry weather flows were discovered, the field crew noted this information within the GIS Data so that they canbe investigated by enforcement personnel. A training procedure will be developed for field personnel to investigate and determine the sources of dry weather flows to determine if they are actually illicit discharges to the MS4. The crew that investigates the dry weather flow will follow simple steps to trace and isolate the source of the dry weather flow. They will make visual observations about the characteristics of the flow so that descriptive data such as color, odor, oil sheen, turbidity, or other such information that could help identify the source. If so equipped, they will perform initial field tests to attempt to determine if trace amounts of certain chemicals are present. They will also take samples if necessary for laboratory analysis Based upon the particular location, they can evaluate the types of facilities located in the proximity to try to identify potential sources of illicit discharges or improper disposal. All of the information will be recorded forms that are developed as a part of the investigation procedure. 7.3.6. The following non -storm water discharges have not been identified as significant contributors of pollutants to the MS4: water line flushing, landscape irrigation, diverted stream flows, rising ground waters,. uncontaminated ground water infiltration, uncontaminated pumped ground water, discharges from potable sources, foundation drains, air conditioning condensation,. irrigation. water, springs, water from crawl space pumps, footing drains, lawn watering, individual residential car washing, flows 14 from riparian habitats and wetlands, declorinated swimming pool discharges, and street wash water. 7.3.7. The outreach program is based upon reaching a majority of the general public and businesses that operate within the City and the ETJ. 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 education and public involvement minimum measures has been supplemented by employee training and other aspects of the good housekeeping minimum measures. 7.3.8. The first step in the decision process was to determine the main pollutants and sources associated with an expanding urban area. Next, the development of the mapping program was considered along with how to coordinate the field investigation of the MS4 in conjunction with the mapping program. The most critical areas are the ones most likely to have illicit connections and illicit discharges. Therefore, they will be mapped and investigated first. The development of an outreach program to reach the majority of the general public ad various businesses was considered next. BMP's were considered based upon the likely success of reaching he most widespread audience of the general public and various businesses. The rationale for this is discussed above. The individual BMP's, measurable goals, and the responsible persons/positions are listed in the BMP summary table for this minimum measure. 7.3.9. Assigning specific persons/positions the responsibility and intermediate milestone dates will allow the tracking of progress against the overall BMP summary table timeline. Annual reports will continue the progress details and track it against the BMP summary timeline. The evaluation process for the measurable goals for this minimum measurable goals for this minimum measure thus becomes a matter of determining if the necessary activities have been accomplished, based on the BMP summary table. The minimum criterion was identification of storm water point source discharge locations from both public & private pipes within 5 years of the initially approved permit. 15 7.4 Construction Site Stormwater Runoff Control 7.4.1.

The City will utilize the regulatory mechanism of the NCDENR Land Quality Section's Erosion and Sediment Control Program and the Division of Water Quality's General Storm Water Permit. The City will not develop, implement, and enforce a separate program for construction site runoff control within the limits of the City and the ETJ. The City will only provide an oversight mechanism with local ordinances. The City will require that a copy of the approval letter from the Land Quality Section be submitted before building or grading permits will be issued if construction activities will result in a land disturbance of an acre or more. 7.5 Post Construction Storm Water Management in New Development and Redevelopment 7.5.1 BMP's and Measurable Goals for Post Construction Runoff Controls ITEM BMP Measurable Goals Year Responsible 1 2 3 14 1 5 Position/Party Update City Code of Ordinances to comply with Development & Design Cit Code NPDES, Phase II Storm Water regulations X X X X X Services Director 2 il2ns torm Water Concept and Design _ 3 Ist..

AN update will be required to bring the code into compliance with the NPDES Phase II regulations. The current code was written to comply with the existing Water Supply Watershed Rules. These regulations will have to be reviewed to determine which provisions are more restrictive, so that the revised code follows the more restrictive regulations. 7.5.3. The current City Code contains several provisions for non-structural BMP's. 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 developments to buffers, screening and interior parking lot landscaping. There are also provisions to set aside areas for recreation and open space. Conditional Use and Overlay districts are also used to comply with the watershed and Flood Damage Prevention Rules. All of these provisions combined have the effect of reducing impervious surface area. The updated code can be used to address additional measures to reduce the percentage of impervious area after development and thus reduce the impacts of polluted storm water runoff. 7.5.4. Structural BMP's are currently required in the City's Water Supply Watershed Protection Ordinance and the Phase 2 Storm Water Ordinance. The Water Supply Watershed Protection Ordinance was created to carry out the requirements of Article 21 of Chapter 143 of the General Statutes of North Carolina to limit pollution exposure to the Catawba River from surface water runoff, since it is used as a municipal water supply source. All storm water controls and structures shall meet the requirements for treatment options approved by the NCDENR Division of Water Quality. Combinations of controls or alternative controls are allowed if they meet the design criteria. The Storm Water Best Management Practices manual published b the NCDENR is used as a guideline. The City Code will have to be updated to require that all new or redevelopment projects meet or exceed the criteria specified by the NPDES Phase II Ordinance regulations including the use of engineered storm water controls. Again, the more restrictive provisions of the various regulations from NCDENR will have to be reflected in the updated code. 7.5.5. The regulatory mechanism used are the City's Code of Ordinances. The City's Planning and Regulation of Development Ordinance specifically applies to all development, public and private, within the City and ETJ. A review of the Zoning Ordinance and other local ordinances has been conducted and proposed modifications to control post -construction storm water runoff, in accordance with NPDES Phase II regulations has been approved. 17 7.5.6. The long-term operation and maintenance of the storm water control structure BMP's is assured by operation and maintenance agreements recorded with the Burke County Register of Deeds. The financial security of the agreement is 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 agreement plan is provided that is consistent with the recorded operation and maintenance agreement. Annual inspections of the storm water control structure are conducted by a qualified professional, and are begun within one year of he filing date of the deed for the storm water control structure. A copy of the annual inspection report will be furnished to the City's Development and Design Services Department, in a format approved for that purpose, within thirty days of the date of the inspection. If necessary, corrective actions will be completed within sixty days of the date of the inspection, by the owner. The City has developed an oversight program for on -site wastewater treatment systems. This program is coordinated with the Burke County Health Department. 7.5.7 The City's current storm water program is outlined in the City's Planning and Regulations of Development Ordinance, which was written to comply with the existing NCDENR Water Supply Watershed Rules. These regulations were reviewed and determined to be in compliance with the NPDES Phase II regulations. Areas outside the City's Water Supply Watershed Protection boundaries were placed under the new Phase 2 Storm Water Protection Rules. The individual BMP's, measurable goals, and the responsible persons/positions are listed in the BMP summary table for this minimum measure. 7.5.8. Assigning specific persons/positions the responsibility and intermediate milestone dates will allow the tracking of progress against the overall BMP summary table timeline. Annual reports will contain the progress details ad track it against the BMP summary timeline. The evaluation process for the measurable goals for this minimum measure thus becomes a matter of determining if the necessary activities have been accomplished, based on the BMP summary table. 18 7.6 Pollution Prevention/Good Housekeeping for Municipal Operations 7.6.1.

The municipal operations that are impacted by the operations and maintenance program will be the public works, public utilities, and recreation departments. The only industrial facility presently subject to a general industrial permit is the City of Morganton Pollution Control Facility 7.6.3. Training programs will be developed for municipal employees that work in such activities as buildings and grounds maintenance, vehicle maintenance, leaf composting, street repair and construction, sanitation, recycling, landscaping, and public utilities. Training programs currently exist for Hazard Communication (OSHA), chemical Hygiene (OSHA), Process Safety Management (OSHA), Risk Management (USEPA), and Pesticides (USEPA/USDA). The municipal employees training can utilize some of the materials that are developed for the outreach programs for public education, public involvement, and illicit discharges. Municipal 19 employees perform many of the same basic functions that involve facility operations and maintenance in private industry. They are also a good source for feed back for developing the programs that are intended for the general public and industry. 7.6.4. Maintenance and inspection activities are only performed within the rights -of -way of the city. The City easements and rights -of -way are only part of the storm water conveyance system within the limits of the City. The City, as a general rule, assumes no responsibility for maintenance, inspection, or improvements on private property. Storm water maintenance and inspection activities outside the rights -of -way are the responsibility of private property owners. Maintenance activities within rights -of -way are normally performed on an as -needed basis by the Public Works Department. The majority of the storm drainage system maintenance is in response to calls from property owners. The remainder of the storm drainage system maintenance work is in response to maintenance needs detected by the Public Works Department. These typically include removal of trash and debris and flow impediments. Street sweeping and mowing are performed based upon a schedule. The proposed maintenance program will be developed using the same basis activities that currently take place. The inspection of the storm water drainage system within the limits of the City and ETJ will take place in conjunction with the mapping operation. All storm water drainage system structures will be inspected and the condition can be documented as a part of that operation. Maintenance work orders can also be generated as a result of that operation. A long-term systematic maintenance program will be out in place as a result of the conditions noted during the inspections. Additional measures will be evaluated as the program is developed. 7.6.5 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 city garage have covered parking/storage areas. Since this is the same complex where vehicles maintenance operations take place, the covered storage and maintenance areas reduce the pollutants discharged into the storm drainage systems. Vehicle fluids are normally removed form paved areas using compounds that absorb the fluids. Additions to the current program could include diversion berms or covers for storm drainage structures that are near fueling and transfer stations. Salt used for deicing activities is currently stored in an enclosed area. Additional measures will be evaluated to reduce the discharge of pollutants from these areas. 7.6.6. Current waste disposal practices do not consider waste removed from the storm drainage system as hazardous material. This material typically IR includes sediment, floatables, broken limbs form bushes/trees, and miscellaneous debris. This material can be disposed of normally or taken to the landfill as necessary. 7.6.7. Flood management projects are non -typical for this area. Regional detention facilities to control flooding have not been necessary. Currently, storm water management concentrates in the controlled release of storm water discharges from new development. The Storm Water Best Management Practices manual published by the NCDENR is also used as a guideline for the quality of storm water discharges. 7.6.8. The review of existing ordinances, in conjunction with the other minimum measures, has determined that all of the necessary ordinance modifications for compliance with Phase II have been identified. 7.6.9. Other evaluations conducted in conjunction with minimum measures indicate compliance with Phase Il regulations.. 7.6.10. The first step in the decision process was to determine the main pollutants and sources associated with municipal operations. Since the municipal operations are located at various facilities, the facilities were reviewed to determine where the most likely sources of possible pollutants exist. Since paved areas are subject to vehicle pollutants, a program to reduce pollutants from municipal parking areas and vehicle storage will be priority. Vehicle maintenance and fueling areas are also areas that need attention because of the possibility of fluid spills. Bulk material storage outdoors can also be a source of pollutants. Moving bulk storage indoors as much as practical will reduce the possibility of pollutants. The use of various chemicals pesticides, herbicides, and fertilizers can result in polluted storm water runoff. A program to evaluate and possibly reduce their usage will reduce pollutants. 7.6.11. Assigning specific persons/positions the responsibility and intermediate milestone dates will allow the tracking of progress against the overall BMP summary table timeline. Annual reports will contain the progress details and track it against the BMP summary timeline. The evaluation process for the measurable goals for this minimum measure thus becomes a matter of determining if the necessary activities have been accomplished, based on the BMP summary table. 21
