10 Public Education and Outreach Descriptive Text: To satisfy this minimum control measure, the operator of a regulated small MS4 needs to: 1. Implement a public education program to distribute educational materials to the community, or conduct equivalent outreach activities about the impacts of storm water discharges on local waterbodies and the steps that can be taken to reduce storm water pollution; and 2. Determine the appropriate best management practices (BMPs) and measurable goals for this minimum control measure. An informed and knowledgeable community is crucial to the success of a storm water management program since it helps to ensure the following: 1. Greater support for the program as the public gains a greater understanding of the reasons why it is necessary and important. Public support is particularly beneficial when operators of small MS4s attempt to institute new funding initiatives for the program or seek volunteers to help implement the program; and 2. Greater compliance with the program as the public becomes aware of the personal responsibilities expected of them and others in the community, including the individual actions they can take to protect or improve the quality of area waters. Number of BMPs associated with control measure: 7 Important Dates: Earliest Start Date: End Date: 6/1/2005 2/28/2011 9

11 Details of BMPs and for Them Beach Monitoring Program Horry County routinely tests beach waters for bacteria in accordance with SCDHEC guidelines. Horry County has posted informational signs at all outfall locations and when swimming advisories are issued by SCDHEC, County staff members post the appropriate warning signs on the beach. This is an on-going activity that will continue through the permit period. Campground Operator and Guest Educational Materials Horry County is in the process of developing targeted educational materials specifically for campgrounds. The materials will be distributed to the campgrounds and training provided to the campground operators to inform them of the issue of fecal bacteria contamination and beach closures. Coastal Waccamaw Stormwater Educational Consortium and Carolina Clear Program Start Date: 6/1/2005 End Date: 2/28/2011 Coastal Waccamaw Stormwater Education Consortium Coastal Waccamaw Stormwater Educational Consortium and Carolina Clear Program - An educational consortium has been created in Horry and Georgetown County that consolidates the educational efforts of Clemson University's Carolina Clear Program, Coastal Carolina University, Waccamaw Riverkeeper, NOAA's Coastal Training Program and others involved in stormwater pollution reduction efforts. The Consortium will be the primary entity responsible for Horry County's Public Education and Outreach Program. This consortium has developed and is delivering a variety of messages aimed at a wide spectrum of audiences from students to working and retired residents as well as the business 10

12 community.. Horry County has committed to participate in the program. The goal of this program is to prepare, produce and disseminate a wide variety of stormwater related educational materials in the participating communities. Horry County will continue to participate in this program for the duration of the permit. Additional information on the Consortium is attached. County Web Site Horry County has a government web site with departmental pages. The Stormwater Department will be posting educational information and have links to the Carolina Clear web site and other pertinent educational web sites. The goal is to post no less than 4 pages of appropriate educational and informative material in the first year and 2 additional pages per year thereafter. In-House Educational Programs Responsible Party: Jackie Taylor, NPDES Coordinator Start Date: 1/1/2006 End Date: 2/28/2011 Horry County has a full-time staff person dedicated to NPDES implementation and coordination. This person is delivering stormwater educational programs to elementary school students through classroom activities and after school programs. At least twenty-four such programs will be presented each year reaching approximately 500 students annually. Public Access Television Station 11

13 Horry County has a public access channel on the local cable network. This will allow broadcast of educational information related to the Stormwater program. The goal is to prepare and air 6 informative slides per year for the duration of the permit. An additional goal is to obtain at least 1 educational video per year and air them six times per year in various time slots. Tourist and Visitor Educational Materials Horry County has developed educational brochures specifically for tourists and visitors. The materials will be distributed to the visitor centers and hotels to inform them of the issue of fecal bacteria contamination and beach closures. Public Participation/Involvement Descriptive Text: To satisfy this minimum control measure, the operator of a regulated small MS4 must: 1. Comply with applicable State, Tribal, and local public notice requirements; and 2. Determine the appropriate best management practices (BMPs) and measurable goals for this minimum control measure. EPA believes that the public can provide valuable input and assistance to a regulated small MS4's municipal storm water management program and, therefore, suggests that the public be given opportunities to play an active role in both the development and implementation of the program. An active and involved community is crucial to the success of a storm water management program because it allows for: 1. Broader public support since citizens who participate in the development and decision making process are partially responsible for the program and, therefore, may be less likely to raise legal challenges to the program and more likely to take an active role in its implementation; 2. Shorter implementation schedules due to fewer obstacles in the form of public and legal challenges and increased sources in the form of citizen volunteers; 3. A broader base of expertise and economic benefits since the community can be a valuable, and free, intellectual resource; and 12

14 4. A conduit to other programs as citizens involved in the storm water program development process provide important cross-connections and relationships with other community and government programs. This benefit is particularly valuable when trying to implement a storm water program on a watershed basis, as encouraged by EPA. Number of BMPs associated with control measure: 6 Important Dates: Earliest Start Date: End Date: 1/1/2005 2/28/

15 Details of BMPs and for Them Alliance with Winyah Rivers Foundation The Winyah Rivers Foundation has implemented a River Keeper Program for the Waccamaw River. Horry County will create an alliance in support of this program to work with the River Keeper to monitor discharges to the river and educate river users and adjacent land owners of pollution threats and prevention techniques. Essay Contest Responsible Party: Jackie Taylor, NPDES Coordinator Start Date: 1/1/2005 End Date: 2/28/2011 Horry County financially supports the Horry Soil and Water Conservation District's annual essay contest for middle school students in Horry County. This support will continue through the term of the permit. Murrells Inlet Special Area Management Plan Horry County is participating in the Murrells Inlet SAMP which has been created and is being managed by SCDHEC. The goal is to reduce pollution and improve the overall quality of the estuary. Stormwater Advisory Board 14

16 Horry County has had public participation since the inception of the Stormwater Program. Stakeholder groups have been involved in creation of the Stormwater Utility, fee structure, ordinances and technical design guide. The current stormwater advisory committee appointed by County Council meets approximately nine times per year these meetings are open to the public and are advertised in accordance with state law. Volunteer Monitoring Program Responsible Party: Jackie Taylor, NPDES Coordinator Start Date: 1/1/2007 End Date: 2/28/2011 Coastal Carolina University and the Waccamaw Riverkeeper have developed a volunteer water quality monitoring program which the County is helping to fund. The County will continue to support the program and promote it through our stormwater website for the duration of the permit. Watershed Boards Start Date: 10/24/2006 End Date: 2/28/2011 Horry County has had Watershed Boards in place for many years. These groups meet regularly to deal with watershed specific issues. The Horry County Stormwater Department will work to improve communication and dialogue with the boards. The exact methods to be utilized have not been determined at this time. The County will continue to attend the watershed meetings and promote personal and group involvement in stormwater issues. 15

17 Illicit Discharge Detection and Elimination Descriptive Text: Recognizing the adverse effects illicit discharges can have on receiving waters, the final rule requires an operator of a regulated small MS4 to develop, implement and enforce an illicit discharge detection and elimination program. This program must include the following: 1. A storm sewer system map, showing the location of all outfalls and the names and location of all waters of the United States that receive discharges from those outfalls; 2. Through an ordinance, or other regulatory mechanism, a prohibition (to the extent allowable under State, Tribal, or local law) on non-storm water discharges into the MS4, and appropriate enforcement procedures and actions; 3. A plan to detect and address non-storm water discharges, including illegal dumping, into the MS4; 4. The education of public employees, businesses, and the general public about the hazards associated with illegal discharges and improper disposal of waste; and 5. The determination of appropriate best management practices (BMPs) and measurable goals for this minimum control measure. Discharges from MS4s often include wastes and wastewater from non-storm water sources. A study conducted in 1987 in Sacramento, California, found that almost one-half of the water discharged from a local MS4 was not directly attributable to precipitation runoff. A significant portion of these dry weather flows were from illicit and/or inappropriate discharges and connections to the MS4. Illicit discharges enter the system through either direct connections (e.g., wastewater piping either mistakenly or deliberately connected to the storm drains) or indirect connections (e.g., infiltration into the MS4 from cracked sanitary systems, spills collected by drain outlets, or paint or used oil dumped directly into a drain). The result is untreated discharges that contribute high levels of pollutants, including heavy metals, toxics, oil and grease, solvents, nutrients, viruses, and bacteria to receiving waterbodies. Pollutant levels from these illicit discharges have been shown in EPA studies to be high enough to significantly degrade receiving water quality and threaten aquatic, wildlife, and human health. Number of BMPs associated with control measure: 8 Important Dates: Earliest Start Date: End Date: 3/1/2006 2/28/

18 Details of BMPs and for Them Detection of Illict Discharges Responsible Party: Thom Roth & Jackie Taylor Start Date: 4/1/2006 End Date: 2/28/2011 Year 1 X Year 2 X Year 3 X Year 4 Year 5 Horry County will be using the methodology detailed in the "Illict Discharge Detection and Elimination Guidance Manual" prepared by The Center for Watershed Protection and Robert Pitt, as the basis for our program. In 2006 we began the process of performing the "desktop assessment" we have gathered extensive data on land uses, soil types, hydrology, and mapped businesses and industries that are potential generators of waterborne pollutants. In 2007 and 2008 this data will be combined with watershed delineations to prioritize watersheds for field investigations which will occur in 2009 and Field Investigation Start Date: 1/1/2008 End Date: 2/28/2011 Year 1 Year 2 Year 3 X Year 4 X Year 5 X Based on the watersheds identified as likely candidates for illicit discharges, field investigations will be conducted to search for illict discharges. Implement an Information Management System for Tracking Illicit Discharges Responsible Party: <Not Assigned>, <Unknown> Start Date: 3/15/2007 End Date: Year 1 Year 2 Year 3 Year 4 Year 5 An information Management System will be used to document all important information gathered concerning illicit discharge detection, elimination and actions taken. This information will be included in annual reports and will detail the following: 17

19 1. The number of Outfalls Screened 2. The number of illicit discharges discovered during outfall screening. 3. The number of illicit discharges discovered as a result of citizen complaints. 4. The number of illicit discharges that were resolved. 5. The number of Dye or Smoke tests conducted. Ordinance Year 1 X Year 2 Year 3 Year 4 Year 5 The Horry County Stormwater Management and Sediment Control Ordinance went into effect Oct. 1, 2000 and contains provisions prohibiting the discharge of pollutants and illicit connections to natural and constructed drainage systems. Has Goal Been Accomplished: YES Reporting System and Investigation Procedures Horry County has a Road and Drainage Hotline that acts as a clearinghouse for complaints and requests for service. This system tracks complaints and reports on the results of investigation and responses. Reports of illicit connections are investigated and appropriate actions taken. Has Goal Been Accomplished: YES Septic System Mapping 18

20 Year 1 Year 2 X Year 3 X Year 4 X Year 5 X Horry County desires to work with SCDHEC to develop a county-wide GIS coverage of all permitted septic system locations. This element will depend on the cooperation of SCDHEC and their ability to provide the necessary records. Storm System Mapping A GIS based County drainage system map has been developed. This mapping will utilize the USGS hydrography maps as the basis for establishing "waters of the state". To this will be added County maintained drainage systems including ditches and piped systems. Locations where these County maintained systems discharge to the "waters of the state" will be identified on the map. The first year of the program will involve compiling all available digital data, converting paper maps and as-built maps to digital format and integrating this data into the GIS mapping system. The second year will involve field work to verify the compiled data and identify gaps in the data. The third year will be used to map the missing features using GPS survey techniques. This mapping will be updated by County personnel. Train Employees Responsible Party: <Not Assigned>, <Unknown> Start Date: 3/15/2007 End Date: Year 1 Year 2 Year 3 Year 4 Year 5 Design and administer a training program to employees that will help them to identify illicit discharges. Construction Site Runoff Control 19

21 Descriptive Text: The Phase II Final Rule requires an operator of a regulated small MS4 to develop, implement, and enforce a program to reduce pollutants in storm water runoff to their MS4 from construction activities that result in a land disturbance of greater than or equal to one acre. The small MS4 operator is required to: 1. Have an ordinance or other regulatory mechanism requiring the implementation of proper erosion and sediment controls, and controls for other wastes, on applicable construction sites; 2. Have procedures for site plan review of construction plans that consider potential water quality impacts; 3. Have procedures for site inspection and enforcement of control measures; 4. Have sanctions to ensure compliance (established in the ordinance or other regulatory mechanism); 5. Establish procedures for the receipt and consideration of information submitted by the public; and 6. Determine the appropriate best management practices (BMPs) and measurable goals for this minimum control measure. Polluted storm water runoff from construction sites often flows to MS4s and ultimately is discharged into local rivers and streams. Of the pollutants listed in Table 1, sediment is usually the main pollutant of concern. Sediment runoff rates from construction sites are typically 10 to 20 times greater than those of agricultural lands, and 1,000 to 2,000 times greater than those of forest lands. During a short period of time, construction sites can contribute more sediment to streams than can be deposited naturally during several decades. The resulting siltation, and the contribution of other pollutants from construction sites, can cause physical, chemical, and biological harm to our nation's waters. For example, excess sediment can quickly fill rivers and lakes, requiring dredging and destroying aquatic habitats.

22 Details of BMPs and for Them Contractor Training and Education Through the Stormwater Educational Consortium, educational classes such as the CEPSCI training, Carolina Clear contractor training have been and will continue to be conducted, as well as informational booths set up at various conferences for contractors and developers. Inspections Horry County currently has an inspection program for all land disturbances greater than 10,000 sf. The inspections are required, as a minimum, prior to the issuance of a certificate of occupancy, or subdivision approval. In most cases at least two inspections are performed for each project. The Department has the ability to issue stop work orders as needed to enforce compliance with the ordinance. Has Goal Been Accomplished: YES Ordinance Year 1 X Year 2 Year 3 Year 4 Year 5 The Horry County Stormwater Management and Sediment Control Ordinance went into effect Oct. 1, Horry County requires that all land disturbance activities greater than 10,000 sf. obtain a permit. Single family residential construction as well as agricultural and timbering activities are exempt. Has Goal Been Accomplished: YES 21

23 Plan Review and Permitting Prior to issuing a Stormwater permit, Plans and stormwater calculations are reviewed to ensure compliance with County ordinances and regulations. Review includes, but is not limited to, Erosion and Sediment Control, BMP selections and water quality. Has Goal Been Accomplished: YES Post-Construction Runoff Control Descriptive Text: The Phase II Final Rule requires an operator of a regulated small MS4 to develop, implement, and enforce a program to reduce pollutants in post-construction runoff to their MS4 from new development and redevelopment projects that result in the land disturbance of greater than or equal to 1 acre. The small MS4 operator is required to: 1. Develop and implement strategies which include a combination of structural and/or non-structural best management practices (BMPs); 2. Have an ordinance or other regulatory mechanism requiring the implementation of post-construction runoff controls to the extent allowable under State, Tribal or local law, 3. Ensure adequate long-term operation and maintenance of controls; 4. Determine the appropriate best management practices (BMPs) and measurable goals for this minimum control measure. Post-construction storm water management in areas undergoing new development or redevelopment is necessary because runoff from these areas has been shown to significantly effect receiving waterbodies. Many studies indicate that prior planning and design for the minimization of pollutants in post-construction storm water discharges is the most cost-effective approach to storm water quality management. There are generally two forms of substantial impacts of post-construction runoff. The first is caused by an increase in the type and quantity of pollutants in storm water runoff. As runoff flows over areas altered by development, it picks up harmful sediment and chemicals such as oil and grease, pesticides, heavy metals, and nutrients (e.g., nitrogen and phosphorus). These pollutants often become suspended in runoff and are carried to receiving waters, such as lakes, ponds, and streams. Once deposited, these pollutants can enter the food chain through small aquatic life, eventually entering the tissues of fish and humans. The second kind of post-construction runoff impact occurs by increasing the quantity of water delivered to the waterbody during storms. Increased impervious surfaces interrupt 22

24 the natural cycle of gradual percolation of water through vegetation and soil. Instead, water is collected from surfaces such as asphalt and concrete and routed to drainage systems where large volumes of runoff quickly flow to the nearest receiving water. The effects of this process include streambank scouring and downstream flooding, which often lead to a loss of aquatic life and damage to property. Number of BMPs associated with control measure: 7 Important Dates: Earliest Start Date: End Date: 3/1/2001 2/28/

25 Details of BMPs and for Them Better Site Design to Reduce Impacts Year 1 Year 2 Year 3 X Year 4 Year 5 The Stormwater Department will work with the County Planning staff, design engineers, planners and the development community to develop standards to encourage better site planning techniques to reduce impervious cover, increase use of innovative water quality BMP's and improve the effectiveness of current BMP's such as detention ponds. This effort will occur in year 3 of the plan. Conservation of Natural Resources Start Date: 3/1/2006 End Date: 2/28/2009 Year 1 X Year 2 X Year 3 X Year 4 Year 5 The Stormwater Department is working with the County Planning staff, conservation groups and the development community to develop standards to strengthen the conservation of natural resources. A bufferordiance is currently being developed. Inspections Horry County currently has one full time inspector for land disturbance permits. This inspector is required, as a minimum to inspect and approve each site prior to the issuance of a certificate of occupancy. In most cases at least two inspections are performed for each project. The Department has the ability to issue stop work orders as needed to force compliance with the ordinance. The inspection program will be expanded to include existing stormwater facilities such as detention ponds and other BMP's in Year 3 of the program. 24

26 Mapping of Existing BMP Facilities Year 1 Year 2 X Year 3 Year 4 Year 5 Horry County will work with SCDHEC-OCRM to develop a database and mapping of all existing detention ponds and other BMP facilities that were permitted prior to implementation of Horry County's permit process. This will effort will occur in Year 2 of the program. This information will be used to create an annual inspection program of these facilities in Year 3. Ordinance The Horry County Stormwater Management and Sediment Control Ordinance went into effect Oct. 1, Horry County requires that all land disturbance activities greater than 10,000 sf. obtain a permit. Single family residential construction as well as agricultural and timbering activities are exempt. The ordinance requires that all developments control stormwater quality through the use of BMP's as shown in the Design Manual. Has Goal Been Accomplished: YES Permanent Maintenance of BMP's Start Date: 7/1/2007 End Date: 2/29/2008 Year 1 X Year 2 X Year 3 Year 4 Year 5 The County will develop a checklist for owners and HOA's explaining maintenance responsibilities. A permanent maintenance agreement will be developed for all stormwater BMP's and require developers to sign over the responsibility for the stormwater system to the appropraite part. This agreement will 25

27 include both inspection and maintenance requirements. This effort will occur in year 2 of the plan. Plan Review and Permitting Start Date: 3/1/2001 End Date: 2/28/2011 Plans and stormwater calculations are reviewed prior to the issuance of a permit. Adequate BMPs needed to meet the Coastal Zone Management Plan are required to be shown on the plans along with supporting calculations. Has Goal Been Accomplished: YES Pollution Prevention/Good Housekeeping Descriptive Text: Recognizing the benefits of pollution prevention practices, the rule requires an operator of a regulated small MS4 to: 1. Develop and implement an operation and maintenance program with the ultimate goal of preventing or reducing pollutant runoff from municipal operations into the storm sewer system; 2. Include employee training on how to incorporate pollution prevention/good housekeeping techniques into municipal operations such as park and open space maintenance, fleet and building maintenance, new construction and land disturbances, and storm water system maintenance. To minimize duplication of effort and conserve resources, the MS4 operator can use training materials that are available from EPA, their State or Tribe, or relevant organizations; 3. Determine the appropriate best management practices (BMPs) and measurable goals for this minimum control measure. The Pollution Prevention/Good Housekeeping for municipal operations minimum control measure is a key element of the small MS4 storm water management program. This measure requires the small MS4 operator to examine and subsequently alter their own actions to help ensure a reduction in the amount and type of pollution that: (1) collects on streets, parking lots, open spaces, and storage and vehicle maintenance areas and is discharged into local waterways; and (2) results from actions such as environmentally damaging land development and flood management practices or poor maintenance of storm sewer systems. While this measure is meant primarily to improve or protect receiving water quality by altering municipal or facility operations, it also can result in a cost savings for the small MS4 operator, since proper and timely maintenance of storm sewer systems can help avoid repair costs from damage caused by age and neglect. Number of BMPs associated with control measure: 6 26

29 Details of BMPs and for Them Catch Basin Cleaning The County currently has a catch basin cleaning crew and equipment however a more systematic program needs to be developed. This will be done in year 1 of the program. County Facility NPS Discharge Policy Year 1 Year 2 X Year 3 Year 4 Year 5 Stormwater will prepare and present to County Council a policy to reduce and minimize NPS pollution on County owned facilities. This will be a year 2 goal. Facility Inventory and Assessment Year 1 X Year 2 X Year 3 Year 4 Year 5 A County facility inventory and assessment to determine type and quantity of non-point source discharges will be performed in years 1 & 2 of the program. Horry County will have a SWPP for it's Fleet Maintenance and Public Works Facility in place by the end of Facility Remediation 28

30 Year 1 Year 2 Year 3 X Year 4 X Year 5 Based on the results of the inventory and assessment, a reduction and remediation plan will be developed for each facility. This will occur in years 3 & 4 of the program Inspection and Enforcement Year 1 Year 2 Year 3 X Year 4 X Year 5 X An annual inspection of each County facility shall be performed in years 3-5 to determine compliance with NPS discharge reduction policy Training Year 1 Year 2 X Year 3 X Year 4 X Year 5 X A training and education program will be developed and presented to all applicable county staff on ways to reduce NPS pollution in the performance of their jobs. This will be completed and presented in Years 2-5 of the program on an annual basis. 29
