A system will be developed for follow up distribution of public education materials regarding proper disposal into storm sewer system for those associated with the illicit discharges. • Water sampling and testing is conducted on a monthly basis by the State of North Carolina. • Suspicious discharges 'kvill be prioritized based on the estimate of' their impact on the watershed. • Investigation of suspicious discharges will be made by visual inspection and/or testing of discharges within the storm drainage system upstream and downstream of the suspicious discharge. Other options that will be considered in locating illicit connections or discharges include televising; the storm sewer or dye testing premises in the area where there is a discharge. Notification will be placed on the doors of residents and businesses alerting them to the possible problem that is is source. investigation and to solicit their assistance in finding; the source. A building -by -building evaluation may also be used in areas where a problem has been isolated to a small area. • Reportable spills (and other reportable events) are reported to the appropriate state agencies. 7.3.5. Outreach: The Town of Kure Beach will be providing Stormwater Public Education for residents, businesses and visitors. Factships are included in the weekly newsletter and an educational brochure and video arc included on the Town website. Signs regarding; pet. waste are posted in various areas of the "['own. 7.3.6. Decision Process. The Stormwater Illicit Discharge Detection and Elimination Program will emphasize prevention of illegal discharges through regulation and education. The ordinance will be enforced as needed, but the emphasis when a discharge is found will be education and elimination of the discharge. The inventory of previous complaints and location of old sanitary sewer lines will be the initial priority areas for visual inspection. Efforts will be made at crass -training; Town staff in recognition of illegal discharges. 7.3.7. Evaluation. All activities related to this Illicit Discharge ]elimination Program wil l be tracked and documented by the Town of Kure Beach.

The Town of Kure Beach is located in New Hanover County, North Carolina and is situated on a barrier island adjacent to historic Fort Fisher State Park. Geographically, the town is located on a narrow island, with the Atlantic Ocean in the east and bordered on the west side by the Intracoastal Waterway. The existing stormwater drainage system utilizes eighteen (18) ocean outfalls to discharge untreated stormwater directly to the surf zone along the recreational beach area. Over 50% of the Town's stormwater runoff is discharged through these ocean outfalls. The remaining volume of stormwater runoff drains by gravity through the MOTSU buffer zone and into the Cape Fear River. The eighteen (18) drains that exist today were installed in 1911 when the old roadway was built. Other drains may have preceded these, but those there today were installed then by the road -builders. Their purpose is to drain storm water away from the road surface. Current ownership is debatable, although it is clear the storm drains are not privately owned, but rather, the North Carolina Department of Transportation - Division of Highways (DOT) and the Town of Kure Beach shares maintenance of them. DOT maintains the drains across their right of way, while the Town maintains the pipes once they reach the shoreline. Recently DOT and the Army Corps of Engineers (COE) partnered in the relocation of the drains at the (former) Hamby Beach area. The Town has extended the pipes to accommodate beach re -nourishment projects and has kept them open over the years. The Town is investigating the feasibility of removing these ocean outfalls and implementing a comprehensive stormwater drainage project. A Feasibility Study has been prepared which outlines the possible options for such a comprehensive project. The concept for a feasible stormwater management project involving the elimination of the eighteen ocean outfalls includes both gravity drainage and pumping. The general scope of the concept project is to collect the runoff in several manifold type conveyances that will gravity drain to several pump stations located along Fort Fisher Boulevard. The stormwater will then be pumped to a ditch and culvert network in the MOTSU buffer zone. The concept project also utilizes a series of stormwater "best management practices" (BPM's) to provide treatment of the first flush (i.e., the first 1-inch of each storm event) to reduce sediment and pollutants prior to discharge. The BPM's include a series of stormwater wetlands, totalirg approximately 20 acres, to be created in the MOTSU buffer zone. These wetlands must be carefully designed to receive gravity flow from the drainage west of 4th Street and pressure flow from the stormwater pump stations located east of 4th Street. The pressure lines from the pump stations will discharge into a stilling basin where the velocity will be slowed and energy dissipated prior to release to the stormwater wetlands. A diversion box will be located in the lower stage of the stilling basin, which will utilize a series of weirs to direct the volume produced by the first flush toward the stormwater wetlands. Stormwater runoff that exceeds the first flush will be diverted around the treatment devices, through stabilized channels, and will directly discharge to the Cape Fear River. The stormwater wetlands will be designed to treat the first flush or the runoff produced by the first 1-inch of rainfall produced from a storm with a recurrence interval of 2-years and 24-hour duration. The temporary pool in the wetlands should be designed to contain the first f - inch of the 2-year storm event, with no volume reduction for pervious area within the watershed. The Town is presently investigating sources of funding for this project. The existing stormwater collection system consists of a network of ditches, pipes, culverts, five stormwater detention basins, and curb & gutter. There is one wet detention basin Jocated near Hamby Avenue that does afford some treatment for a portion of the stormwater discharging toward Ocean Outfall #1 at Ocean View Avenue. The Kure Beach topography is such that there is a slight ridge that runs from the northeast to southwest. The Kure Beach drainage area east of "approximately" 4Th Street drains toward the Atlantic Ocean while the area to the west of 4th Street drains toward the Cape Fear River. This ridge does not run exactly parallel to 4th Street, but is skewed slightly in the NE to SW direction. 1.4a MS4 maintenance activities Piping - Inspected, minor cleaning and repair on an as needed basis. Open ditches - Mow and clean annually. Detention Basins - Inspected, minor cleaning and repair on an as needed basis. 1.4b Maintenance FTE How many full time equivalent positions are used to provide maintenance services, annually? : 2-full time maintenance; 1-superintendent (subject to change as required to meet system requirements). 1.4.c Inspection frequency How often is the system inspected for maintenance problems?

TMDL Identification Do you discharge to a TMDL controlled water body? Presently No, but the Cape Fear River TMDL is in progress. 2. RECEIVING STREAMS 2.1 Major River Basin Cape Fear 2.2 Primary Receiving Streams Receiving Stream Name: Cape Fear - 35%; Direct discharge to Atlantic Ocean — 65% Stream Segment: Hennikers Ditch Water Quality Classification: SA; HQW Use Support Rating: NIA Water Quality Issues: There are currently eighteen (18) stormwater ocean outfalls discharging untreated stormwater runoff into the coastal waters along the Kure Beach recreational shoreline. The eighteen ocean outfalls discharge more than half of the stormwater runoff from the Kure Beach drainage area. There have been documented water quality issues in the coastal waters at and near these outfalls 2.3 Significant Water Quality Issues Are there significant water quality issues detailed in the attached application report? Yes. Presently the discharge of untreated stormwater directly to the surf zone along the Kure Beach recreational shoreline, via the 18 ocean outfall pipes, is a serious concern. Elevated bacteria counts have been measured in the vicinity of the outfall pipes. The outfall pipes discharge in the public swimming areas. See Feasibility Study for further details and plan of action for removal of the outfall pipes. 2.4 Discharge to Seas Do you discharge to territorial seas, oceans or within the contiguous zone? Yes 0 3. EXISTING WATER QUALITY PROGRAMS 3.1 Local Water Quality Programs The Coastal Area Management Act (CAMA), 1974, requires the establishment of a cooperative program of coastal land management between local government and the State of North Carolina for preparing, adopting and enforcing local land use plans. CAMA requires that local governments within the 20 coastal counties prepare land use plans that provide for the protection, preservation, orderly development and management of the coastal area of North Carolina. 3.2 State Programs The following State programs are implemented in the Kure Beach jurisdictional area: A.

Stormwater Management Plan 7.1 Public Education and outreach on Stormwater Impacts What pollutant source(s) are you trying to address and why? List the targeted pollutants and give a brief explanation as to why these are selected. Fecal Coliform from pet waste and malfunctioning sewer systems, nutrients from lawn and garden care activities, petroleum and antifreeze for roadway surfaces. Write a narrative description of the approach you are going to take in your outreach program. Target various public sectors, including schools, businesses and citizens, through educational campaigns to inform citizens on illicit discharges, reporting, improper waste disposal, sources of nutrient and fecal coliform loading and actions that can be taken to minimize the pollutants. Local police and fire personnel will be educated in illicit discharge detection, reporting and spill response. Fliers, bill inserts, newspaper ads and TV public service announcements will be utilized to inform the public. Decision Process: describe the decision process used to create this program element. The stormwater management committee that was appointed by the Town Council recognized the need for a stormwater education program to inform the citizens about the impacts of polluted runoff to waterways and coastal waters along the Kure Beach recreational shoreline. The specific focus is to inform citizens about the impacts of polluted runoff and to foster understanding and acceptance for the newly established program. 7.2 Public Involvement and Participation Program Are you going to comply with the public hearing requirement to meet this minimum control measure? Yes, the State's public notice of the draft NPDES stormwater permit will serve as the required public involvement. There is no local requirement to involve the public or hold a hearing on the NPDES permit application. Describe the Public [notice Process including the name and title of the person responsible for compliance. The public may comment on the draft NPDES stormwater permit during the State's public notice comment period. Kure Beach is dedicated to meeting the intent of the State and Federal NPDES requirements. 7.3 Illicit Discharge Detection and Elimination: Storm Sewer System Map — See Appendix B 7.3.1 Storm Sewer System Map — See Appendix B 9 Describe how you are going to complete a storm sewer system map of outfall locations. What sources of information will you use? What form will the map take (digital, paper map)? What method will you use to verify the accuracy of the locations? Will you do field verification and if so, will you use any specific technology? How will you update the map, once data collection begins? Who will keep the map current? Where will the map be located within the organization for the public to view or review if desired? The eighteen (18) stormwater ocean outfalls have been identified and mapped. Other storm sewer system outfalls will be mapped using GIS. An independent engineering firm will be contracted to perform the field survey and mapping services. The Director of Public Works will be responsible for keeping the GIS database updated. Current storm sewer maps will be maintained at the Kure Beach Public Works office at 401 H. Avenue, Kure Beach, NC. 7.3.2 Regulatory Mechanism Do you have an ordinance in place that prohibits non-stormwater from your drainage system? Action is pending to amend the existing stormwater ordinance to address illegal dumping or illicit connections to the drainage system. This ordinance will define what is allowable in the storm drainage system, describe enforcement actions, and give right of entry on to private property to inspect and/or remove an illicit connection. Does it also address illegal dumping or illicit connections to the drainage system? Does it define what is allowable in the storm drainage system? Does it describe enforcement actions? Does it give you right of entry on to private property to inspect and/or remove an illicit connection? If you answer no to any of the above detailed questions, you need to update your ordinance and include those pieces that are missing. This ordinance will be amended to addresses illegal dumping or illicit connections to the drainage system, define what is allowable in the storm drainage system, describe enforcement actions, and give right of entry on to private property to inspect and/or remove an illicit connection. The revised stormwater ordinance will address illegal dumping or illicit connections to the drainage system, define what is allowable in the storm drainage system, describe enforcement actions, and give right -of -entry on private property to inspect and/or remove an illicit connection. 7.3.3 Enforcement Actions Describe the methodology you will use to take enforcement actions needed when you find an illicit connection. Include the process you will follow if different from the method of adopting or amending your current ordinance. Illicit discharge enforcement is a four -step process consisting of: - Inform the violator. - Give violator time to repair or remove. - Assess civil penalties and tines. - Town will correct the problem and bill the offender. 10 7.3.4 Detection and Elimination Describe the plan you are going to follow to find and eliminate illicit connections. Address spills and illegal dumping controls as well. Include procedures for locating high priority areas in the community; procedures for tracing the. source of an illicit connection; procedures for removing the discharge and procedures for program evaluation and assessment. Illicit connections will be identified through annual storm sewer system inspections. Water quality sampling will be performed at discharge points where dry weather flows are found if an obvious source cannot be determined through observation. Identified illicit discharges will be tracked and periodically evaluated through the NPDES annual reporting process. Spills will be reported to appropriate local authorities and local police and fire personnel will be trained in illicit discharge detection and spill response. How will you find illicit connections? Illicit connections will be identified through annual storm sewer system inspections. How will you address spills, within your own operation and within the community? Spills will be reported to appropriate local authorities and local police and fire personnel will be trained in illicit discharge detection and spill response. How will you eliminate an illicit connection or discharge? Not Available, the ordinance will require that we notify the party responsible for the illicit discharge, with a certain number of days. If not done in the time allowed, the party is subject to criminal fines. The Town then goes in a will do the removal of the illicit discharge and charge the responsible party How will you evaluate your program and make changes over time? The Plan will be reviewed annually by the appointed stormwater committee 7.3.5 Non stormwater Discharges How will the following discharges be categorized? Illicit or Allowable 1.

Stormwater Management Permits Do you currently have development standards that address stormwater management on new or redevelopment projects that disturb more than one acre of property? Yes, The Town of Kure Beach's Ordinance pending ordinance entitled Storm Water Management is the primary regulation governing stormwater in the town. Are your standards in an ordinance or other regulatory format that requires plan reviews, long-term maintenance, and use of BMPs for water quality controls? Yes Describe current program and how it meets the requirements of the Permit. How does it address non-structural controls? The ordinance requires plan reviews, long-term maintenance and use of BMPs for water quality controls for new and redevelopment projects of 1 acre or more. The Town's stormwater program requires on -site detention of storm water for the 10-year storm event. In addition to controlling the quality of storm water, projects are also required to meet State guidelines for water quality under the State Stormwater Management Program. Plans for the new development are submitted for review and approval to Zoning and Planning and then Public Works. New construction plans and any existing construction plans that exceed 50% of the existing site will go through the technical review process with appropriate staff members, i.e. Utility director, Stormwater manager, Utility Superintendent. How does it address structural controls? Structural controls may include wet detention ponds, dry ponds, and infiltration. 13 Of all your current practices and strategies, list the ones that will be used as on -going BMPs under this permit. Evaluate the run-off of the overflow structures, check landscaping plants and test water quality for enhancing structures owned by the community to add water quality controls. 7.5.2 Maintenance Program Maintenance crews will be working on the stormwater system daily, i.e. cleaning ditches of debris, cleaning pipes of debris. Inspection of structures will be completed on an annual schedule. 7.5.3 Fecal Coliform Program Once detected to eliminate immediately. 7.5.4 SA Waters Program We measure and monitor daily from our effluent at the sewer plant, and in conjunction with the Cape Fear River keeper, who monitors the surrounding waters 7.5.5 Non -Structural BMPS See 7.5.1 7.5.10 Structural BMPs See 7.5.1 7.5.11 Regulatory Mechanism Do you have a regulatory mechanism to address post -construction controls for water quality? YES- The Town Ordinance; Design and Construction of Stormwater Management Measures" 7.5.12 Operation and Maintenance Describe how you will ensure long term operation and maintenance of BMPs. The Town of Kure Beach will put in place a full time Stormwater Management section that will start up on July 1, 2005. Town now has an adopted ordinance, with development fees, and monthly user fees in which to generate revenue needed to fund the section. 14 7.5.9 Decision Process Describe the process you followed in determining your plan of action for this minimum control measure. — BMPs and Town Ordinances What are your priority areas? — Removal of the existing 18 stormwater ocean outfalls. What conditions exist in your community that are unique or require tailored BMP's? - The existing eighteen (18) stormwater ocean outfalls currently discharging untreated stormwater runoff into the coastal waters along the Kure Beach recreational shoreline is a situation unique to this community. The eighteen ocean outfalls discharge more than half of the stormwater runoff from the Kure Beach drainage area. The remaining volume of stormwater runoff drains by gravity through the MOTSU buffer zone and into the Cape Fear River. As previously mentioned, the Town is exploring the feasibility of removing these outfalls and diverting the runoff to a series of BMPs located on the Cape Fear side of the island. The Town is presently investigating sources of funding for this project. 7.6 Pollution Prevention/Good Housekeeping for Municipal Operations 7.6.1 Affected Operations What are you currently doing that could be considered as BMP strategies under the permit? List measures and check to indicate that you are going to use these to comply with the permit requirements. List the municipal operations that will be impacted by this measure. — The Public Works Department will be impacted by this measure, by adding additional workload. The Building Inspections Department will enforce fines. Police & Fire Department will undergo special training. 7.6.2 Municipal Industrial Facilities List the municipal operations that must have a separate NPDES permit.

Sincerely, Betty L. Medlin Mayor cc: Jim Dugan, Mayor Pro Tem Henry E. "Sonny" Becker, Jr. Director of Public Works Town of Kure Beach Stormwater Feasibility Study PLANNER IN CHARGE SUMMARY Background -How We Got to Where We Are Over the past three years the Town of Kure Beach has proactively sought to eliminate the 18 stormwater culverts that discharge regularly into the Atlantic Ocean along their public beach front. Their concern stems not only from the damaging, affect the non -point source pollution could have on the swimmers, but also the long-term impact this may have on the coastal ecosystem. Clean Beaches are what draw millions of visitors to Kure Beach and Pleasure Island for family vacations. The prospect of unsafe, polluted beaches negatively impacts the tourism -based economy and overall quality of life for the entire area. Tourism and the economy are indeed directly tied to clean water... beaches polluted by stormwater cost everyone. With funding assistance provided by a CAMA Grant from the North Carolina Division of Coastal Management, The Mayor and Town Commissioners of Kure Beach conducted a grass roots study to develop a Plan of Action for the Removal of the Stormwater Outfalls. This study, facilitated by the Care Fear Council of Governments with technical expertise provided by the NC Shellfish Sanitation, DOT, NCDENR-WQ, DCM, the US Army COE,'MOTSU, and Town Commissioner James Dugan was completed in June, 2002. The net result of the study was a plan to eliminate the drains and divert the Stormwater away from the beach into a stormwater wetland, located in the undeveloped explosive arc buffer zone west of Town. Whether or not that was feasible, and specifically how it could be accomplished was the rationale for hiring T.A. Allen engineering to conduct this Feasibility Study. The Allen Plan Terry Allen was already familiar with the area, having worked extensively for the US Army Military Ocean Terminal Sunny Point (MOTSU), owners of the above - mentioned buffer area targeted for the stormwater wetlands. His firm fully tested the previous groups hypothesis, and weighed the stormwater wetland approach with various other best management practice (BMP) alternative storm water solutions. It was his professional opinion that the stormwater wetland approach was not only feasible, but also the most economical and environmentally sensitive way to achieve a sustainable solution. The Allen Plan calls for removal of the pipes and diversion of the stormwater to sump basins (3-5) where it would be pumped over the island ridge into gravity flow engineered conveyances to created stormwater wetlands (4-5acre/ea) in the MOTSU buffer Zone. The exact number and location of the sump -pump stations, and the location of the wetlands has yet to be determined, pending project design. Because the pumps will likely be near residential property, he has recommended quieter electric pumps, two at each location that would cycle to prevent wear and tear. Similar pumps have been used in near by coastal communities with much success. Due to these factors that will not be known until the project Is designed, he could only offer an opinion of total project costs, but has given a range up to 8.5 million dollars. Technical Advisory_Gomm ttee During the course of his engineering analysis, the technical advisory committee used in the citizen Plan of Action Study was reconvened to give guidance and input from their agency perspective. They met twice during the study period, and submitted their final thoughts on the project via emalls attached as exhibits to this summary. Their general support and enthusiasm for a long-term sustainable solution to the problem was reflected in their comments. During the course of the design and construction phase each of their agencies will be have permitting oversight, but none indicated that they felt the project could not be permitted - another key factor to determining the ultimate feasibility of the project. MOTSU-The Real €sjMte lEsue Perhaps the greatest obstacle for this study was to ensure that MOTSU was 'not opposed to locating the four wetlands on their property. The Army insisted that any encroachment onto the property required US Army Headquarters approval, and must demonstrate impending public necessity. They also opposed any option that would result in frequent use of the area by persons, as the intent of the buffer zone is to establish a safety zone that mirrors the estimated explosive arc from detonation of military explosives at MOTSU. Therefore, no people and no structures are allowed. The constructed stormwater wetland achieved that goal, and consequently, their willingness to consider the project. The twenty acres needed could be leased at rate substantially below the prevailing market rate, thus adding to the feasibility of the project. Citizen Participation Once the advisory committee and MOTSU completed their reviews, and the Allen Plan was reduced to paper and drawings, the Town of Kure Beach advertised and conducted a public hearing at their April meeting to receive input from the community. There was one question about the impact of the project to the existing ecosystem and several questions about who was going to pay for it. The one was assured that every effort would be made to have minimal impact to the ecosystem of the island and that any harm would be greatly outweighed by the elimination of the NPS pollution currently being discharged. Funding issues were addressed satisfactorily by the Town's stated intent to seek grant funding.

However, they stayed the course and now have facilitated the development of an excellent and proven feasible plan to eliminate the ocean outfalls and achieve a sustainable environmentally sensitive solution to a long-term environmental problem. It cannot be stated to often how dependent Pleasure Island and the Cape Fear Region is upon Tourism. We built the case early showing the direct relationship clean water has to the areas` economic and environmental sustainability. The study proves there is a feasible solution to this problem, and steps must be taken to remove the outfalls now. The Town is encouraged to aggressively pursue grant funding from every possible source to ensure clean and safe beaches, and a robust tourism economy for future generations.
