                                  S. C. DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL
                               STORMWATER MANAGEMENT AND SEDE%IENT REDUCTION HANDBOOK




                      1. Synopsis:
                      This handbook is a compilation of existing South Carolina stormwater management regulations and
                      supporting information that applicants will need to proceed through the land disturbance permitting
                      process. The objective of this document is to create a comprehensive reference for individuals who will
                      be submitting a stormwater management and sediment reduction permit application for approval to the
                      Department of Health and Environmental Control (DHEC). This handbook summarizes the application
                      process and sets forth the minimum standards and design specifications for land disturbing activities
                      that require stormwater permits. The supporting information includes application forms, checklists,
                      sediment control design aids and other useful information. This document references pertinent sections
                      from the S. C. Stormwater Management and Sediment Reduction regulations, the NPDES General
                      Permit for Stormwater Discharges from Construction Activities and the Coastal Zone Management
                      Program Refinements which are included as appendices.


                      11. Scope:
                      A stormwater mana ement plan in compliance with the requirements of existing regulations must be
                      submitted for most land disturbing activities in South Carolina. Appendix A contains a copy of the
                      S. C. Stormwater Management and Sediment Reduction regulations. 'Me DHEC Office of Ocean and
                      Coastal Resource Management (OCRM), formerly the S. C. Coastal Council, administers the
                      stormwater mana ement program in the following eight coastal counties: Beaufort, Berkeley,
                      Charleston, Colleton, Dorchester, Georgetown, Horry, and Jasper. The stormwater permitting
                      program for the rest of the state is implemented by DHEC's Bureau of Water Pollution Control, which
                      now includes parts of the former Land Resources Conservation Commission.


                      M. Projects Requiring Permits:
                      All land disturbing activities in the state that win disturb greater than two (2) acres that are not
                      specifically exempt require a stormwater mana ement permit prior to construction. In the eight (8)
                      coastal counties, if the activity is within one-half (1/2) mile of a receiving waterbody, projects
                      disturbing two (2) acres or less must also obtain a land disturbance permit (see next section).


                      IV. Permit Applicability:
                      Specific requirements of the permit application and approval process are based on the amount of actual
                      land disturbance and, if the activity is in the Coastal Zone, the project's proximity to a receiving
                      waterbody. The permit application procedure is as follows:
                      (1) For activities involving two (2) acres or less of actual land disturbance and which are not part
                      of a larger common plan of development or sale, the person responsible for the activity shall submit a
                      simplified stormwater mana ement and sediment control plan meeting the requirements of R.72-307H
                      in Appendix A and the reporting form found in Appendix D. This plan does not require approval by
                      the Department of Health and Environmental Control and does not require preparation or certification
                      by a registered engineer, landscape architect, or Tier B land surveyor. The DHEC staff does have the
                      authority to conduct site inspections on these projects to insure compliance with the submitted plans.



                                                                          I









                  (2) For activities involving two (2) acres or less of actual land disturbance which are within one-
                  half (1/2) mile of a receiving waterbody in the Coastal Zone. The Coastal Zone Management
                  Program Refinements (Appendix B) state that "stormwater management and sediment reduction plan
                  submittal and regulatory approval shall be required for those smaller projects located within 1/2 mile of
                  a receiving waterbody." Particular emphasis shall be placed on the Wowing projects in this category:
                  (a)     All commercial buildings which will handle hazardous chemicals (including gasoline, kerosene,
                          diesel fuel, nutrients, etc.).
                  (b)     All commercial buildings and parking/runway areas with greater than one (1) acre of
                          impervious surface (building and parking).
                  (c)     All commercial buildings and parking/runway areas with greater than one-half (1/2) acre of
                          impervious surface located directly adjacent to a saltwater (critical) area.
                  (d)     All residential subdivision developments located directly adjacent to a saltwater (critical) area.
                  (e)     All projects impacting Geographical Areas Of Particular Concern (GAPC's).
                  These activities (a-e) must meet the requirements of R.72-3071 in Appendix A and must have the plans
                  and specifications prepared by a registered engineer, landscape architect or Tier B land surveyor.
                  Other activities in this category require a permit but must only meet the submittal requirements of
                  R.72-307H which do not require preparation by a licensed professional.
                  (3) For activities involving more than two (2) acres and less than rive (5) acres of actual land
                  disturbance which are not part of a larger common plan of development or sale, a simplified
                  permitting approval process will be used meeting the requirements of R.72-3071 in Appendix A. Plans
                  and specifications for these activities will be prepared by professional engineers, landscape architects or
                  tier B land surveyors.
                  (4) For activities involving rive (5) acres or greater of actual land disturbance, the requirements of
                  R.72-305 and R.72-307 from Appendix A and requirements of General Permit SCR100,000 in
                  Appendix C apply. Plans and specifications for these activities will be prepared by professional
                  engineers, landscape architects or Tier B land surveyors.
                  Additional design requirements for certain projects in the Coastal Zone as adopted in the Coastal Zone
                  Management Program Refinements are contained in Appendix B. These requirements address design
                  needs for activities located in close proximity to receiving waterbodies, bridge projects, golf courses,
                  mines and landfills.

                  V. Application Forms and Checklists:
                  Appendix D contains all the necessary application forms and checklists to use in a stormwater
                  mana ement and sediment reduction permit submittal package.



                  VI. Plan Submittal:

                  The responsible agent should do a preliminary analysis to determine which of the different categories a
                  project would fall under and then submit the appropriate application form and information required on
                  the checklist. The initial submittal package should include only one (1) paper copy of the stormwater
                  mana ement and sediment reduction plans and corresponding calculations. After the plans have been
                  reviewed to determine compliance with the regulations, the DHEC plan reviewer will contact the
                  applicant/engmeer and request necessary changes or notify the individual that the plans are in
                  compliance. When the plans have been determined to be in compliance then the applicant/engineer
                  shall send either four (4) additional paper copies or.one (1) mylar copy for stamp approval. One copy
                  of the plans is for the engineer/agent, one is for the owner, one is for the contractor and must be
                  available onsite at all times and one copy is for the DHEC inspector.



                                                                     2










                      VII. NPDES General Permit Coverage
                      Any construction project disturbing five (5) acres or greater must obtain either NPDES general permit
                      coverage or an individual NPDES permit. NPDES General Permit coverage under SCR100,000 can
                      be obtained by the above referenced submittal information including application form # 3306
                      (9/94), plans and specifications. Therefore, application form # 3306 (9/94) shall serve as the
                      Notice Of Intent (NOI) for NPDES general permit coverage for most land disturbance activities.
                      If a project has a disturbed acreage of five (5) acres or more and is exempt from the requirements of
                      Title 48 Chapter 14 by Section 40 and by R.72-302 but not exempt from the requirements of 40 CFR
                      122 and SCRIOO,000, then the EPA Notice of Intent (NOI) found in Appendix D must be submitted.
                      Filing this form guarantees that a Pollution Prevention Plan (PPP) has been developed and will be
                      maintained on site.
                      The S. C. Department of Transportation (SCDOT) must comply with SCR.100,000 and Regulation 72-
                      400. All Department of Transportation projects are required to file the EPA Notice of Intent (NOI)
                      form at least 48 hours prior to start of construction. A copy of the plans developed in compliance with
                      R.72-400 must be submitted at the time the contract is awarded.



                      VHL Notification of Initiation of Land Disturbance Activity
                      Notification shall be sent to the appropriate DHEC plan review office with carbon copies to the local
                      DHEC district offices prior to initiation of the land disturbing activity. A list of the DHEC District
                      offices is included in the front of this handbook. Prior to completion of the project, a final inspection
                      may be requested from the appropriate DHEC district or OCRM office.


                      IX. Design Guidelines For Sediment/Erosion Control
                      The stormwater management regulations require that when   storinwater runoff drains to a single outlet
                      from land disturbing activities which disturb ten (10) acres or more then a sediment basin must be
                      designed to meet a removal efficiency of 80 percent for suspended solids or 0.5 MUL peak settleable
                      concentration, which ever is less. The efficiency shall be calculated for disturbed conditions for the 10-
                      year 24-hour design event. There are computer software packages available that can be used to
                      calculate the removal efficiencies of certain sediment control practices. in addition, Appendix E
                      contains a report titled "Engineering Aids and Design Guidelines for Control of Sediment in South
                      Carolina" which can be referenced when calculating sediment removal efficiencies.
                      Activities that have between five (5) and ten (10) acres of land disturbance area draining to a single
                      outlet may incorporate other practices besides a sediment basin to achieve the equivalent removal
                      efficiency of 80 percent for suspended solids or 0.5 MUL peak settleable solids concentration.
                      Specific site conditions and/or topography may eliminate the need for removal efficiency calculations.
                      Construction activities that disturb less than five (5) acres do not require sediment calculations but the
                      design of these projects must include sediment control best management practices during construction.



                      X. Rainfall Data for South Carolina

                      Appendix G contains rainfall data and rainfall-erosivity factors (R factors) for all South Carolina
                      counties to be used in hydrology and sedinientology calculations. Appendix F contains additional
                      information such as the eroded particle size distributions and D15 values for all South Carolina soils.







                                                                         3











                  XI. Fees:
                  A fee of fifty (50) dollars per disturbed acre up to a maximum Of $1000 is required for all land
                  disturbance activities over two (2) acres. There is no fee charged for government activities (local,
                  state, and federal) or for projects that disturb two (2) acres or less. An application for a waiver or a
                  variance must include a $100 fee. In order to estimate the area of land disturbance for subdivisions
                  without exact build out plans, use the following formula:
                  Amount of Disturbance = 2[Max Restricted Building Size][Number of Lots] + ROW areas
                        Right of Way (ROW) areas include clearing for roads, utilities, easements etc.
                  There is an additional $75 fee for all projects that will disturb five (5) acres or more and must therefore
                  obtain NPDES general permit coverage. There are no exemptions from this fee so local governments,
                  schools and other entities that are exempt from the $50/disturbed acre fee must submit this fee as part
                  of their land disturbance package. This is a yearly fee and applicants will be billed in October for
                  active permits as of July 1. If coverages are no longer necessary ( i.e. site is stabilized), a Notice of
                  Termination (NOT) must be filed to stop the coverage and end the billing process. All coverages under
                  the General Permit SCR100,000 must pay the $75 initially to begin coverage and then will be billed for
                  subsequent fiscal years.


                  XII. Inspections:
                  The DHEC staff will conduct periodic site inspections on all land disturbing activities. The person
                  responsible for the land disturbing activity shall notify the appropriate inspection agency before
                  initiation of construction and upon project completion when a final inspection will be conducted to
                  ensure compliance with the approved stormwater mana ement and sediment control plan. DHEC or
                  any other responsible inspection agency shall, for inspection purposes, do all of the following items:
                           (1)      Ensure that the approved stormwater management and sediment control plans are on
                                    the project site and are complied with;
                           (2)      Ensure that every active site is inspected for compliance with the approved plan on a
                                    regular basis;
                           (3)      Provide the person responsible for the land disturbing activity a written report after
                                    every inspection.
                           (4)      Notify the person responsible for the land disturbing activity in writing when
                                    violations are observed, describing the:
                                    (a)      Nature of the violation;
                                    (b)      Required corrective action; and
                                    (c)      Time period for violation correction.



                  XEIL Violations and Enforcement:

                  Violations of the stormwater regulations will occur when (a) a site with an approved stormwater permit
                  is not in compliance with the issued permit or (b) a land disturbing activity is underway and the agent
                  has not acquired the necessary permit. Enforcement procedures will vary according to the seventy of
                  the violation but might include imposmg fines or issuing cease and desist orders. Violations of the
                  S. C. Pollution Control Act as prescribed by SCRIOO,000 may subject the applicant to a civil penalty
                  of up to $10,000 per violation per day. Additional information on enforcement procedures is
                  contained in Section 72-312 of Appendix A.




                                                                       4










                     XIV. Best Management Practices (BMPs):
                     Appendix H contains a table and illustrations of some of the stormwater management and sediment
                     reduction best management practices (BMPs) used in South Carolina. The existing conditions
                     determined from site surveys will aid in selecting the most effective BMPs to use when designing a
                     plan for permit submittal. Included in the BMP section is a sample subdivision lot detail (Figure 6)
                     that can be used to illustrate the necessary sediment control practices that a contractor for an individual
                     home site in a subdivision may have to incorporate. Additional methods of stormwater management
                     and sediment control can be found in "A Guide to Site Development and Best Management Practices
                     for Stormwater Management and Sediment Control" distributed by the Department.

                      FINAL REGULATIONS



                      LAND RESOURCES CONSERVATION COMNIISSION

                      CHAPTER 72

                               Statutory Authority: 1976 Code, Title 48, Chapter 14


                      72-300 Standards for Stormwater Management and Sediment Reduction
                      Synopsis:
                      These proposed regulations pursuant to the Stormwater Management and Sediment Reduction Act of
                      1991 establish the procedure and minimum standards for a statewide uniform program for stormwater
                      mana ement and sediment reduction with the option of being operated locally. The regulations
                      establish the procedure for local governments or conservation districts to apply for program component
                      delegation. They also establish the criteria to be met for delegation. Minimum standards and
                      specifications are established for land disturbing activities that require a permit.
                      The proposed regulations encourage mana ement of stormwater and sediment on a watershed basis.
                      Criteria and procedures are established for designating watersheds and creating storrawater utilities.
                      When the law becomes effective, it will be implemented in a phased approach as listed in the
                      regulations.

                   72-300. Scope.
                        A.  Stormwater runoff is a source of pollution of waters of the State, and may add to existing
                            flooding problems. The implementation of a statewide storinwater management and sediment
                            control program will help prevent additional water quantity and quality problems and may
                            reduce existing problems.
                        B.  Stormwater management and sediment control plan approvals are necessary prior to engaging
                            in any land disturbing activity related to residential, commercial, industrial or institutional land
                            use which are not specifically exempted or waived by these regulations.
                        C.  To the extent possible, the Commission intends to delegate the provisions of these regulations
                            to local goverrments. Those program provisions which are subject to delegation include
                            stormwater management and sediment control plan approval, construction and maintenance
                            inspections, enforcement, and education and training.
                        D.  The Commission encourages the implementation of the Stormwater Management and Sediment
                            Reduction Act on a watershed basis by local governments. The Commission recognizes that
                            all jurisdictions may not have the resources available to implement this type of program
                            immediately. However, the comprehensive approach of implementing the program on the
                            watershed basis will allow for planned, orderly development in a watershed.
                        E.  The implementation of a stormwater utility represents a comprehensive approach to program
                            funding and implementation. The activities which may be undertaken by a stormwater utility
                            include not only assessment, collection, and funding activities, but also carrying out provisions
                            of adopted stormwater management plans. These provisions may include contracting for such
                            services as project construction, project maintenance, project inspection, and enforcement of
                            installation and maintenance requirements imposed with respect to approved land disturbing
                            activities.

                            B.  Implementing agencies with responsibility for plan review and approval may grant waivers
                                from the stormwater mana ement requirements of these regulations for individual land
                                disturbing activities provided that a written request is submitted by the applicant containing
                                descriptions, drawings, and any other information that is necessary to evaluate the proposed
                                land disturbing activity. A separate written waiver request shall be required if there are
                                subsequent additions, extensions, or modifications which would alter the approved stormwater
                                runoff characteristics to a land disturbing activity receiving a waiver.
                                (1)  A project may be eligible for a waiver of stormwater mana ement for both quantitative
                                     and qualitative control if the applicant can demonstrate that the proposed project will
                                     return the disturbed area to a pre-development nmoff condition and the pre-development
                                     land use is unchanged at the conclusion of the project.
                                (2)  A project may be eligible for a waiver or variance of stormwater mana ement for water
                                     quantity control if the applicant can demonstrate that:
                                     (a) The proposed project will have no significant adverse impact on the receiving natural
                                         waterway or downstream properties; or
                                     (b) The imposition of peak control requirements for rates of tormwater runoff would
                                         aggravate downstream flooding.
                                (3) The implementing agency will conduct its review of the request for waiver within 10
                                     working days. Failure of the implementing agency to act by end of the tenth working day
                                     will result in the automatic approval of the waiver.
                            C. The implementing agency with responsibility for plan review and approval may grant a written
                                variance from any requirement of these regulations if there are exceptional circumstances


                                                                            15









                            applicable to the site such that strict adherence to the provisions of these regulations will result
                            in unnecessary hardship and not fulfill the intent of these regulations. A written request for
                            variance shall be provided to the plan approval agency and shall state the specific variances
                            sought and the reasons with supporting data for their granting. The plan approval agency shall
                            not grant a variance unless and until sufficient specific reasons justifying the variance are
                            provided by the applicant. The implementing agency will conduct its review of the request for
                            variance within 10 working days. Failure of the implementing agency to act by the end of the
                            tenth working day will result in the automatic approval of the variance.


                   72-303. Commission Responsibilities.
                       A.   The Commission is responsible for the implementation and supervision of the stormwater
                            mana ement and sediment control program which is established by Chapter 14, Title 48, S.C.
                            Code.

                       B.   The schedule for implementing the Stormwater Management and Sediment Control Act (48-14-
                            10, et. seq.) has been established by the Commission as follows:
                            (1) These regulations are effective and applicable to all land disturbing activities of five acres
                                and greater on October 1, 1992 regardless of program status at the local level. Local
                                governments with existing local programs as of this date shall require that persons
                                responsible for land disturbing activities on sites with disturbed areas of five acres or
                                greater comply with these regulations. Local governments may request assistance from
                                the Commission to implement these regulations on these sites. If a local government does
                                not have a local program on October 1, 1992, the Commission and others shall function as
                                the implementing agencies.

                            prior to the effective date of these regulations may continue to administer the existing program
                            until the scheduled implementation date for the local government.




                                                                       16

                      E.  Requests for delegation of program elements must be submitted by local governments or
                          conservation districts within six months of the effective date of these regulations, and by
                          January first of subsequent years if delegation is desired at a future date. The Commission
                          shall approve, approve with modification, or deny such a request on or before April first of
                          the year for which delegation is sought.
                      F.  The S.C. Coastal Council shall assist the Commission in reviewing all requests for delegation
                          of program elements from local governments in the counties of Beaufort, Berkeley,
                          Charleston, Colleton, Dorchester, Georgetown, Jasper and Horry to ensure that the delegated
                          program elements are consistent with the Coastal Zone Management Program.
                          The S.C. Coastal Council, in coordination with the Commission, will serve as the
                          implementing agency for these regulations in the jurisdictions of the local governments which
                          do not seek delegation of program elements in the counties of Beaufort, Berkeley, Charleston,
                          Colleton, Dorchester, Georgetown, Horry and Jasper.
                      G.  If the Commission denies a request for delegation, the local government or conservation
                          district may appeal the decision of the Commission by requesting an administrative hearing
                          within 30 days after receipt of written notification as described in R.72-313.
                      H.  Delegation of authority for one or more program elements may be granted for a maximum
                          time frame of three years. After three years a new application to the Commission must be
                          made. Over the tune frame for which delegation has been granted, the Commission will
                          evaluate delegation implementation, coordinate review findings with the delegated authority,
                          and determine if the new delegation should be granted.
                      1.  A delegated authority may sub-delegate program elements, with Commission concurrence, to a
                          conservation district, regional council of government or other responsible entity or agency.
                      J.  The Commission shall maintain, and make available upon request, a listing of the current
                          status of delegation for all jurisdictions within the State.
                      K.  Any local government that has adopted a stormwater mana ement and/or sediment control
                          program prior to the effective date of these regulations may request approval of any, or all,
                          components of its existing program within six months of the effective date of these regulations.
                          The Commission shall give priority to the approval, approval with modification or disapproval
                          of these requests. The local government " continue to administer the existing program
                          during the review process by the Commission. Efficiency and effectiveness of the existing
                          program shall be considered in the review process.
                          (1) The Commission shall approve a delegation request upon determining that the
                              implementation of the existing program by the local government equal or exceed the
                              requirements, criteria, standards and specifications of these regulations.
                          (2) If the request for delegation of program components are disapproved, the local government
                              may appeal the decision of the Commission by requesting an administrative hearing within
                              30 days after receiving written notification of the disapproval as described in R.72-313.
                      L.  If the Commission determines that a delegated program falls below acceptable standards
                          established by these regulations, delegation may be suspended. During a period of suspension,
                          the Commission shall be responsible for implementation of the program element. The
                          Commission shall collect fees based on R.72-306 for use when the delegation is suspended.
                          The following actions may be cause for suspension if they represent a continuing pattern of
                          action or in-action:





                                                                   18

                                     in the event of off-site sediment or stormwater damage resulting from non-compliance with
                                     the approved plan.
                                 (2) Failure of the implementing agency to assess a fine when a violation has not been
                                     corrected within the specified time frame.
                                 (3) Failure of the implementing agency to stop work when a violation has resulted in off-site
                                     damages.
                                 (4) Failure of the implementing agency to force compliance with an approved plan.
                                 (5) Failure of the delegated program to comply with the provisions of its application for
                                     delegation.
                            M. Upon suspension of the delegation, the implementing agency has the right to file an appeal
                                 within 30 days of the notification of the suspension following procedures listed in R.72-313.
                                 The Commission shall administer the program during the appeal process.


                       72-305.   Permit Application and Approval Process.
                            A.   After the effective date of these regulations, unless a particular activity is exempted by these
                                 regulations, a person may not undertake a land disturbing activity without an approved
                                 stormwater management and sediment control plan from the appropriate plan approval agency
                                 that is consistent with the following items:
                                 (1) Chapter 14, Title 48, South Carolina Code, relating to erosion and sediment control and
                                     stormwater management, and
                                 (2) These regulations, or duly adopted county or municipal ordinances or programs that are
                                     adopted as a part of the delegation process and set mininium standards equivalent to these
                                     regulations.
                            B. Specific requirements of the permit application and approval process are generally based on the
                                 extent of the land disturbing activity. The permit application and approval procedure is as
                                 follows:

                                 (1) For land disturbing activities involving two (2) acres or less of actual land disturbance
                                     which are not part of a larger common plan of development or sale, the person responsible
                                     for the land disturbing activity shall submit a simplified stormwater management and
                                     sediment control plan meeting the requirements of R.72-307H. This plan does not require
                                     approval by the implementing agency and does not require preparation or certification by
                                     the designers specified in R.72-305H and R.72-305I.
                                 (2) For land disturbing activities involving more than two (2) acres and less than five (5) acres
                                     of actual land disturbance which are not part of a larger common plan of development or
                                     sale, a simplified permitting and approval process will be used meeting the requirements
                                     of R.72-307I. These activities are required to utilize Best Management Practices (BMP's)
                                     to control erosion and sediment and to utilize appropriate measures to control the quantity
                                     of stormwater runoff. Plans and specifications for these activities will be prepared by the
                                     designers cited in R.72-305H and R.72-305I. The implementing agency will review there
                                     submissions within a ten working day period. if action is not taken by the end of the
                                     review period, the plan will be considered approved.
                                 (3) For land disturbing activities disturbing five (5) acres or greater, the requirements of
                                     R.72-305 and R.72-307 wflI apply. However, the use of measures other than ponds to
                                     achieve water quality improvement are recommended on sites containing less than ten (10)
                                     disturbed acres. Plans and specifications for these activities will be prepared by the
                                     designers specified in R.72-305H or R.72-305I.
                                 (4) These requirements may be modified on a case-by-case basis to address specific
                                     stormwater quantity or quality problems or to meet S.C. Coastal Council or other
                                     regulatory requirements. Requests for waivers or variances from these requirements will


                                                                            19









                                be made in accordance with the provisions of R.72-302.
                            (5) When the land disturbing activity consists of the construction of a pond, lake or reservoir
                                which is singly built and not part of a permitted land disturbing activity, the following
                                procedures will apply:
                                (a)  A storinwater management and sediment control plan will not be required if the pond,
                                     lake or reservoir is permitted under the S.C. Dams and Reservoirs Safety Act or has
                                     received a Certificate of Exemption from the S.C. Dams and Reservoirs Safety Act.
                                     Best management practices should be used to minimize the impact of erosion and
                                     sediment.
                                (b)  A stormwater management and sediment control plan will be required for the
                                     construction of all ponds, lakes or reservoirs not meeting the conditions in R.72-
                                     305B(S)(a) that otherwise meet the size requirements for stormwater mana ement and
                                     sediment control plan approval.
                       C.   A stormwater management and sediment control plan or an application for a waiver shall be
                            submitted to the appropriate plan approval agency by the person responsible for the land
                            disturbing activity for review and approval for a land disturbing activity, unless otherwise
                            exempted. The storinwater mana ement and sediment control plan shall contain supporting
                            computations, drawings, and sufficient information describing the manner, location, and type
                            of measures in which stormwater runoff will be managed from the entire land disturbing
                            activity. The appropriate plan approval agency shall review the plan to determine compliance
                            with the requirements of these regulations prior to approval. The approved stormwater
                            management and sediment control plan shall serve as the basis for water quantity and water
                            quality control on all subsequent construction.
                       D.   All storinwater mana ement and sediment control plans submitted for approval shall contain
                            certification by the person responsible for the land disturbing activity that the land disturbirig
                            activity will be accomplished pursuant to the approved plan and that responsible personnel will
                            be assigned to the project.
                       E.   All stormwater management and sediment control plans shall contain certification by the person
                            responsible for the land disturbing activity of the right of the Commission or implementing
                            agency to conduct on-site inspections.
                       F.   The stormwater and sediment mana ement plan shall not be considered approved without the
                            inclusion of an approval stamp with a signature and date on the plans by the appropriate plan
                            approval agency. The stamp of approval on the plans is solely an acknowledgement of
                            satisfactory compliance with the requirements of these regulations. The approval stamp does
                            not constitute a representation or warranty to the applicant or any other person concerning the
                            safety, appropriateness of effectiveness of any provision, or omission from the stormwater and
                            sediment plan.
                       G.   When the local conservation district is not the plan approval agency, the conservation district
                            may request to review and comment on storinwater management and sediment control plans.
                            Failure of the conservation district to provide comments by the date specified by the local
                            implementing agency will not delay the approval of the stormwater mana ement and sediment
                            control plans by the implementing agency.
                       H.   All storinwater mana ement and sediment control plans submitted to the appropriate plan
                            approval agency for approval shall be certified by the designer. The following disciplines may
                            certify and stamp/seal plans as allowed by their respective licensing act and regulations:
                            (1) Registered professional engineers as described in Title 40, Chapter 22.
                            (2) Registered landscape architects as described in Tide 40, Chapter 28, Section 10, item (b).

                                                                        20








                           1.  Pursuant to Title 40, Chapter 22, Section 460, stormwater management and sediment control
                               plans may be prepared by employees of the federal government and submitted by the person
                               responsible for the land disturbing activity to the appropriate plan approval agency for
                               approval.
                           J.  These regulations do not prohibit other disciplines or Certified Professionals, including, but not
                               limited to, Certified Professional Erosion and Sediment Control Specialists, which have
                               appropriate background and experience from taking active roles in the preparation of the plan
                               and design process. All plans and specifications submitted to the appropriate plan approval
                               agency for approval shall be stamped/sealed by those listed in R.72-305H or prepared by
                               employees of the federal government under R.72-305I.
                           K.  Approved plans remain valid for 5 years from the date of an approval. Extensions or renewals
                               of the plan approvals will be granted by the plan approval agency upon written request by the
                               person responsible for the land disturbing activity.
                           L.  Approvals of land disturbing activities which were approved prior to the effective date of these
                               regulations shall remain in effect for the original term of the approval. For land disturbing
                               activities which were not initiated during the original term of approval, the person responsible
                               for the land disturbing activity shall resubmit the stormwater management and sediment control
                               plan to the appropriate plan approval agency for review and approval subject to the
                               requirements of these regulations.
                           M.  Upon receipt of a completed application for sediment and stormwater Mana ement, the
                               appropriate plan approval agency shall accomplish its review and have either the approval or
                               review comments transmitted to the applicant within 20 working days. If notice is not given to
                               the applicant or if action is not taken by the end of the 20 working day period, the applicants
                               plan will be considered approved.
                           N.  One year after the effective date of Chapter 14, Title 48 of the Code of Uws of South
                               Carolina, a federal agency or facility may not undertake a land disturbing activity unless the
                               agency has submitted a stormwater management and sediment control plan for the specific
                               activity to the Commission and the plan has been approved.
                               In lieu of submitting individual plans for approval, the federal agency or facility may submit
                               an application for a general permit to the Commission for approval.
                           0.  A local government or special purpose or public service district may request a general permit
                               for its regulated activities from the Commission. If a local government's or special purpose
                               or public service district's request is approved, individual stormwater mana ement and
                               sediment control plans for regulated land disturbing activities will not be required.



                      72-306. Fees.

                           A. The fees associated with the plan review and approval process inspection and enforcement shall
                               be set by the implementing agency. If permit fees are established, they shall be established in
                               accordance with the following items:
                               (1) Delegation of program elements will depend, to a large extent, on fimding and personnel
                                   commitments. If the delegated jurisdiction has a source of funding that is provided
                                   through local revenues, then the implementation of the delegated component will not
                                   necessitate the imposition of a permit fee to cover the cost of the delegated program
                                   component.
                               (2) In the event that one component of an overall stormwater management and sediment
                                   control program is not fimded through the use of general or special funds, a non-
                                   refundable permit fee may be collected at the time that the stormwater management and
                                   sediment control plan or application for waiver or variance is submitted or approved. The


                                                                          21









                                permit fee will provide for the unfanded costs of plan review, administration and
                                management of the permitting office, construction review, maintenance inspection, and
                                education and training. The plan review or permit approval agency shall be responsible
                                for the collection of the permit fee. Unless all program elements in a county or
                                municipality have been delegated to a single agency, the ftmds collected not supporting the
                                plan review function shall be distributed to the appropriate agencies.
                           (3)  The number of needed personnel and the direct and indirect expenses associated with those
                                personnel shall be developed by the agencies requesting delegation in a specific
                                jurisdiction. Those expenses will then form the basis for determining unit plan approval
                                costs by the local government.
                       B.  Where the Commission is the implementing agency, the Commission may assess a fee not to
                           exceed $50.00 per disturbed acre up to a maximum of $1000.00. No fee will be charged for
                           land disturbing activities which disturb two acres or less. The Commission may also charge a
                           fee not to exceed $100.00 to review an application for a waiver or variance from the
                           requirements of these regulations. No fee will be charged for extensions or renewal of plan
                           approval unless there are significant changes to the plans.
                       C.  A maintenance fee may be required on approvals granted for stormwater mana ement
                           structures that will be maintained by a local government.

                                   criteria.
                               (6) Additional information necessary for a complete project review may be required by the
                                   appropriate plan approval agency as deemed appropriate. This additional information may
                                   include items such as public sewers, water lines, septic fields, wells, etc.
                           B.  Specific requirements for the erosion and sediment control portion of the stormwater
                               management and sediment control plan approval process include, but are not limited to, the
                               following items. The appropriate plan approval agency may modify the following items for a

                                   (i) Removal of sediment controls.
                               Changes to the sequence of construction operations may be modified by the person conducting
                               the land disturbing activity or their representative and do not constitute a violation unless
                               measures to control stormwater runoff and sediment are not utilized.
                               (3) The plans shall contain a description of the predominant soil types on the site, as described
                                   by the appropriate soil survey information available through the Commission or the local

                          C. Specific requirements for the permanent stormwater mana ement portion of the stormwater
                               management and sediment control plan approval process include, but are not limited to, the
                               following items. The appropriate plan approval agency may modify the following items for a
                               specific project or type or project.
                             (1) It is the overall goal of the Commission to address stormwater management on a
                                   watershed basis to provide a cost effective water quantity and water quality solution to the
                                   specific watershed problems. These regulations will provide general design requirements
                                   that must be adhered to in the absence of Designated Watershed specific criteria.



                                                                        23









                          (2)   All hydrologic computations shall be accomplished using a volume based hydrograph
                                method acceptable to the Commission. The storm duration for computational purposes for
                                this method shall be the 24-hour rainfall event, SCS distribution with a 0. 1 hour burst
                                duration time increment. The rational and/or modified rational methods are acceptable for
                                sizing individual culverts or storindrains that are not part of a pipe network or system and
                                do not have a contributing drainage area greater than 20 AC. The storm duration for
                                computational purposes for this method shall be equal to the time of concentration of the
                                contributing drainage area or a minimum of 0. 1 hours, whichever is less.
                          (3)   Stormwater management requirements for a specific project shall be based on the entire
                                area to be developed, or if phased, the initial submittal shall control that area proposed in
                                the initial phase and establish a procedure and obligation for total site control.
                          (4)   Water quantity control is an integral component of overall stormwater management. The
                                following design criteria for flow control is established for water quantity control
                                purposes, unless a waiver is granted based on a case-by-case basis:
                                (a) Post-development peak discharge rates shall not exceed pre-development discharge
                                    rates for the 2- and 10- year frequency 24-hour duration storm event. Implementing
                                    agencies may utilize a less frequent storm event (e.g. 25-year, 24-hour) to address
                                    existing or future stormwater quantity or quality problems.
                                (b) Discharge velocities shall be reduced to provide a nonerosive velocity flow from a
                                    structure, channel, or other control measure or the velocity of the 10-year, 24-hour
                                    storm runoff in the receiving waterway prior to the land disturbing activity,
                                    whichever is greater.
                                (c) Watersheds, other than Designated Watersheds, that have well documented water
                                    quantity problems may have more stringent, or modified, design criteria determined
                                    by the local government that is responsive to the specific needs of that watershed.
                          (5) Water quality control is also an integral component of stormwater mana ement. The
                                following design criteria is established for water quality protection unless a waiver or
                                variance is granted on a case-by-case basis.
                                (a) When ponds are used for water quality protection, the ponds shall be designed as
                                    both quantity and quality control structures. Sediment storage volume shall be
                                    calculated considering the clean out and maintenance schedules specified by the
                                    designer during the land disturbing activity. Sediment storage volumes may be
                                    predicted by the Universal Soil Loss Equation or methods acceptable to the
                                    Commission.
                                (b) Stormwater runoff that drains to a single outlet from land disturbing activities which
                                    disturb ten acres or more shall be controlled during the land disturbing activity by a
                                    sediment basin where sufficient space and other factors allow these controls to be
                                    used until the final inspection. The sediment basin shall be designed and constructed
                                    to accommodate the anticipated sediment loading from the land-disturbing activity and
                                    meet a removal efficiency of 80 percent suspended solids or 0.5 MLJL peak settleable
                                    solids concentration, whichever is less. The outfall device or system design shall
                                    take into account the total drainage area flowing through the disturbed area to be
                                    served by the basin.
                                (c) Other practices may be acceptable to the appropriate plan approval agency if they
                                    achieve an equivalent removal efficiency of 80 percent for suspended solids or 0.5
                                    ML/L peak settleable solids concentration, which ever is less. The efficiency shall
                                    be calculated for disturbed conditions for the 10-year 24-hour design event.
                                (d) Permanent water quality ponds having a permanent pool shall be designed to store
                                    and release the first 1h inch of runoff from the site over a 24 hour period. The
                                    storage volume shall be designed to accommodate, at least, % inch of runoff from
                                    the entire site.
                                (e) Permanent water quality ponds, not having a permanent pool, shall be designed to
                                    release the first inch of runoff from the site over a 24-hour period.


                                                                      24









                                      (f)  Permanent infiltration practices, when used, shall be designed to accept, at a
                                           minimum, the first inch of runoff from all impervious areas.
                                      (g)  For activities in the eight coastal counties of Beaufort, Berkeley, Charleston,
                                           Colleton, Dorchester, Georgetown, Jasper and Horry, additional water quality
                                           requirements may be imposed to comply with the S.C. Coastal Council Stormwater
                                           Management Guidelines. If conflicting requirements exist for activities in the eight
                                           coastal counties, the S.C. Coastal Council guidelines will apply.
                                (6)   Where ponds are the proposed method of control, the person responsible for the land
                                      disturbing activity shall submit to the approving agency, when required, an analysis of the
                                      impacts of stormwater flows downstream in the watershed for the 10- and 100-year
                                      frequency storm event. The analysis shall include hydrologic and hydraulic calculations
                                      necessary to determine the impact of hydrograph timing modifications of the proposed
                                      land disturbing activity, with and without the pond. The results of the analysis will
                                      determine the need to modify the pond design or to eliminate the pond requirement.
                                      Lacking a clearly defined downstream point of constriction, the downstream impacts shall
                                      be established, with the concurrence of the implementing
                                (7)   Where existing wetlands are intended as a component of an overall stormwater
                                      management system, the approved stormwater management and sediment control plan
                                      shall not be implemented until all necessary federal and state permits have been obtained.
                                (8)   Designs shall be in accordance with standards developed or approved by the Commission.
                                (9)   Ease of maintenance must be considered as a site design component. Access to the
                                      stormwater mana ement structure must be provided.
                                (10)  A clear statement of defined maintenance responsibility shall be established during the
                                      plan review and approval process.
                                (11)  Infiltration practices have certain limitations on their use on certain sites. These
                                      limitations include the following items:
                                      (a)  Areas draining to these practices must be stabilized and vegetative filters established
                                           prior to runoff entering the system. Infiltration practices shall not be used if a
                                           suspended solids filter system does not accompany the practice. If vegetation is the
                                           intended filter, there shall be, at least a 20 foot length of vegetative filter prior to
                                           stormwater runoff entering the infiltration practice;
                                      (b)  The bottom of the infiltration practice shall be at least 0.5 feet above the seasonal
                                           high water table, whether perched or regional, determined by direct piezometer
                                           measurements which can be demonstrated to be representative of the maximum height
                                           of the water table on an annual basis during years of normal precipitation, or by the
                                           depth in the soil at which mottling first occurs;
                                      (c)  The infiltration practice shall be designed to completely dram of water within 72
                                           hours;
                                      (d)  Soils must have adequate permeability to allow water to infiltrate. Infiltration
                                           practices are limited to soils having an infiltration rate of least 0.30 inches per hour.
                                           Initial consideration will be based on a review of the appropriate soil survey, and the
                                           survey may serve as a basis for rejection. On-site soil borings and textural
                                           classifications must be accomplished to verify the actual site and seasonal high water
                                           table conditions when infiltration is to be utilized;
                                      (e)  Infiltration practices greater than three feet deep shall be located at least 10 feet from
                                           basement walls;
                                      (f)  Infiltration practices designed to handle runoff from impervious parking areas shall be
                                           a minimum of 150 feet from any public or private water supply well;
                                      (g)  The design of an infiltration practice shall provide an overflow system with measures
                                           to provide a non-erosive velocity of flow along its length and at the outfall;
                                      (h)  The slope of the bottom of the infiltration practice shall not exceed five percent.
                                           Also, the practice shall not be installed in fill material as piping along the fill/natural
                                           ground interface may cause slope failure;


                                                                              25









                                 (i) An infiltration practice shall not be installed on or atop a slope whose natural angle
                                      of incline exceeds 20 percent.
                                      Clean outs will be provided at a minimum, every 100 feet along the infiltration
                                      practice to allow for access and maintenance.
                            (12) A regional approach to stormwater management is an acceptable alternative to site specific
                                 requirements and is encouraged.
                        D. All stormwater management and sediment control practices shall be designed, constructed and
                            maintained with consideration for the proper control of mosquitoes and other vectors.
                            Practices may include, but are not limited to:
                            (1)  The bottom of retention and detention ponds should be graded and have a slope not less
                                 than 0.5 percent.
                            (2)  There should be no depressions in a normally dry detention facility where water might
                                 pocket when the water level is receding.
                            (3)  Normally dry detention systems and swales should be designed to drain within three (3)
                                 days.
                            (4)  An aquatic weed control program should be utilized in permanently wet structures to
                                 prevent an overgrowth of vegetation in the pond. Manual harvesting is preferred.
                            (5)  Fish may be stocked in permanently wet retention and detention ponds.
                            (6)  Normally dry swales and detention pond bottoms should be constructed with a gravel
                                 blanket or other measure to minimize the creation of tire ruts during maintenance
                                 activities.

                        E. A stormwater management and sediment control plan shall be filed for a residential
                            development and the buildings constructed within, regardless of the phasing of construction.
                            (1)  In applying the stormwater management and sediment control criteria, in R.72-307,
                                 individual lots in a residential subdivision development shall not be considered to be
                                 separate land disturbing activities and shall not require individual permits. Instead, the
                                 residential subdivision development, as a whole, shall be considered to be a single land
                                 disturbing activity. Hydrologic parameters that reflect the ultimate subdivision
                                 development shall be used in all engineering calculations.
                            (2)  If individual lots or sections in a residential subdivision are being developed by different
                                 property owners, all land-disturbing activities related to the residential subdivision shall be
                                 covered by the approved stormwater management and sediment control plan for the
                                 residential subdivision. Individual lot owners or developers may sip a certificate of
                                 compliance that all activities on that lot will be carried out in accordance with the
                                 approved stormwater management and sediment control plan for the residential
                                 subdivision. Failure to provide this certification will result in owners or developers of
                                 individual lots developing a stormwater mm ement and sediment control plan meeting the
                                 requirements of R.72-307.
                            (3)  Residential subdivisions winch were approved prior to the effective date of these
                                 regulations are exempt from these requirements. Development of new phases of existing
                                 subdivisions which were not previously approved shall comply with the provisions of these
                                 regulations.
                       F. Risk analysis may be used to justify a design storm event other than prescribed or to show that
                            rate and volume control is detrimental to the hydrologic response of the basin and therefore,
                            should not be required for a particular site.
                            (1) A complete watershed hydrologic/hydraulic analysis must be done using a complete
                                 model/procedure acceptable to the implementing agency. IMe level of detail of data
                                 required is as follows:
                                 (a) Watershed designation on the 7.5 minute topo map exploded to a minimum of 1"



                                                                        26









                                   (b)  Inclusion of design and performance data to evaluate the effects of any Structures
                                        which effect discharge. Examples may be ponds or lakes, road crossings acting as
                                        attenuation structures and there may be others which must be taken into account.
                                   (c)  Land use data shall be taken from the most recent aerial photograph and field checked
                                        and updated.
                                   (d)  The water surface profile shall be plotted for the conditions of pre- and post-
                                        development for the 10-, and 100-year 24-hour storm.
                                   (e)  Elevations of any structure potentially damaged by resultant flow shall also be shown.
                               (2) Based on the results of this type of evaluation, the certified plan reviewer representing the
                                   implementing agency shall review and evaluate the proposed regulation waiver or change.


                           G.  The general permit application for use by federal, local governments, or special purpose or
                               public service districts shall contain, as a minimum, standard plans and specifications for
                               stormwater management and erosion and sediment control; methods used to calculate
                               storrawater runoff, soil loss and control method performance; staff assigned to monitor land
                               disturbing activities and procedures to handle complaints for off-site property owners and
                               jurisdictions.
                               This general permit will be valid for a period of three years and will be subject to the same
                               review criteria by the Commission as that of the delegated program elements.
                               The use of the general permit classification does not relinquish a land disturbing activity from
                               the requirements of these Regulations. Rather, the general permit precludes that activity from
                               the necessity of a specific plan review for each individual project.
                               Approval of a general permit does not relieve any agency from the conditions that are part of
                               the general permit approval regarding the implementation of control practices as required by
                               the general permit. Failure to implement control practices pursuant to conditions included in
                               the general permit may result in the revocation of the general permit and the requirement of
                               the submission of individual plans for each activity.
                           H.  The stormwater mana ement and sediment control plan required for land disturbing activities
                               of two (2) acres or less which are not part of a larger common plan of development or sale
                               shall contain the following information, as applicable:
                               (1) An anticipated starting and completion date of the various stages of land disturbing
                                   activities and the expected date the final stabilization will be completed;
                               (2) A narrative description of the stormwater management and sediment control plan to be
                                   used during land disturbing activities;
                               (3) General description of topographic and soil conditions of the tract from the local soil and
                                   water conservation district;
                               (4) A general description of adjacent property and a description of existing structures,
                                   buildings, and other fixed improvements located on surrounding properties;
                               (5) A sketched plan (engincer's, Tier B surveyor's or landscape architect's seal not required)
                                   to accompany the narrative which shall contain:
                                   (a)  A site location drawing of the proposed project, indicating the location of the
                                        proposed project in relation to roadways, jurisdictional boundaries, streams and rivers;
                                   (b)  The boundary lines of the site on which the work is to be performed;
                                   (c)  A topographic map of the site if required by the implementing agency;
                                   (d)  The location of temporary and permanent vegetative and structural storrawater

                   72-309. Criteria For Designated Watersheds.
                        The concept of designated watersheds is intended, not only to prevent existing water quantity and
                        water quality problems from getting worse, but also to reduce existing flooding problems and to
                        improve existing water quality or meet State Water Quality Standards through a reduction of the
                        impacts of NPS pollution in selected watersheds. Further, the designation of watersheds under this
                        section may also be used to protect watersheds which do not currently have significant water
                        quality or quantity problems, but which require protection in order to avoid or mitigate the
                        occurrence of future problems which might impair current or protected multiple water uses or
                        maportant water resources within the watershed. Criteria is established for designated watersheds
                        and these criteria will depend on whether the specific problems of the watershed are water quantity
                        or water quality oriented. Water quantity and water quality concerns will be considered in all
                        designated watersheds, but the overall emphasis for each designated watershed will depend on its
                        existing and future water quality and quantity issues as well as consideration of the multiple
                        offstream, and instream water uses within the watershed.
                        A.  To initiate consideration of a watershed for Designated Watershed status, a watershed shall be
                            recommended by a local government or combinations of local governments through the
                            passage of a local ordinance to the Commission. Upon recommendation to the Commission,
                            the Commission shall publish the request in the State Register and contact all involved agencies
                            at the local and state level within 30 days after receipt of the designation request and their
                            input received prior to any consideration of the designation is made.
                        B.  Included with the recommendation of a watershed for Designated Watershed status to the
                            Commission shall be an identification of the specific problems that exist in the watershed so
                            that the pursuit of a watershed study is warranted. Designation as a Designated Watershed
                            requires approval by the Commission, the South Carolina Water Resources Commission and
                            the South Carolina Department of Health and Environmental Control. A significant water
                            quantity or water quality problem must exist that would support this designation. Also,
                            inclusion of a watershed as a Designated Watershed will necessitate a public hearing process.
                            The process of designating a watershed shall be based on the following information:
                            (1)      An estimate of the potential for land disturbing activities to be initiated in the basin
                                     which would be regulated under this regulation. This estimate could utilize historical
                                     and projected population growth, land use data, and other such appropriate measures
                                     to estimate the nonpomt source pollution contribution or stormwater nmoff which
                                     could be reduced or avoided,
                            (2)      An inventory of the offstream and instream. water uses in the watershed to quantify
                                     and characterize the benefits associated with reducing current or avoiding future water
                                     resources problems in the watershed. These could include water supply intakes, State
                                     navigable waters, recreational resources, fisheries resources, wetlands, or other such
                                     important uses,
                            (3)      Water quality data, collected through either the statewide water quality inventory, or
                                     other special studies inclusive of benthic macroinvertebrate data,
                            (4)      Historical and estimated flood damage and/or estimated flood protection benefits to
                                     both private and public property in the watershed,
                            (5)      Status of current or description of proposed State and Federal flood protection and
                                     flood plain mana ement program(s) and activities in the watershed, and
                            (6)      Dangers to public health and welfare.
                        C.  Following an adequate review of the recommendation, staff of the Commission, South Carolina
                            Water Resources Commission, and the South Carolina Department of Health and
                            Environmental Control shall meet to review and discuss their decision regarding designation.
                            The staff shall prepare a statement in support of, or objection to, the proposed designation
                            within 120 days following receipt of the recommendation by the Commission. The statement
                            shall be voted upon by the appointed commissioners of each respective agency. Ex-officio


                                                                         30









                              members of the South Carolina Water Resources Commission representing the Land Resources
                              Conservation Commission and the South Carolina Department of Health and Environmental
                              Control shall abstain from voting regarding designation at the meeting of the South Carolina
                              Water Resources Commission. Approval by each of the three agencies shall constitute
                              designation.
                          D.  Upon approval of designation, a Watershed Advisory Committee shall be established to advise
                              and provide guidance in the development and conduct of the watershed master plan. The
                              Commission, South Carolina Water Resources Commission, and the South Carolina
                              Department of Health and Environmental Control will appoint the Watershed Advisory
                              Committee which shall include State, District, local government representatives, and also
                              representatives of the regulated community within the watershed and other persons which may
                              be affected by the plan.
                          E.  The general components contained in the actual watershed study shall be the following items:
                              (1)  Stormwater quantity or water quality problem identification,
                              (2)  The overall needs of the watershed including the additional impacts of new land disturbing

                   72-310. Criteria For Implementation of a Stormwater Utility.
                       The implementation of a stormwater utility will necessitate the development of a local utility
                       ordinance or special taxing assessment prior to its implementation, pursuant to Chapter 9, Title 4,
                       1976 Code of Laws as amended by Act 114 1991. There are essential components that an
                       ordinance must contain to function as a funding mechanism for stormwater management and those
                       components shall include, but not be limited to, the following items:
                       A.   The financing of a stormwater utility with a user charge system must be reasonable and
                            equitable so that each user of the stormwater system pays to the extent to which the user
                            contributes to the need for the stormwater system, and that the charges bear a substantial
                            relationship to the cost of the service. The use of county and municipal taxpayer rolls and
                            accounting systems are allowed for the assessment and collection of fees.
                       B.   The intent of the utility must be clearly defined regarding program components that are to be
                            funded through the utility. Those components may include but not be limited to the following
                            activities:

                            (1) Preparation of comprehensive watershed master plans for stormwater management,
                            (2) Annual inspections of all stormwater mana ement facilities, both public and private,
                            (3) Undeftaking regular maintenance, through conawting or other means, of stormwater
                                management structures that have been accepted for maintenance.
                            (4) Plan review and inspection of sediment control and storrawater management plans and
                                practices, and
                            (5) Retrofitting designated watersheds, through contracting or other means, to reduce existing
                                flooding problems or to improve water quality.
                       C.   The authority for the creation of the stormwater utility and the imposition of charges to finance
                            sediment and stormwater activities is conferred in Chapter 14, Title 48, South Carolina Code.
                            The application of a stormwater utility by means of a local ordinance or other means shall not
                            be deemed a limitation or repeal of any other powers granted by State statute.
                       D.   The creation of a stormwater utility shall include the following components:
                            (1) The boundaries of the utility, such as watersheds or jurisdictional boundaries as identified
                                by the local governing body,
                            (2) The creation of a management entity,
                            (3) Identification of stormwater problems,
                            (4) Method for determining utility charges,
                            (5) Procedures for investment and reinvestment of funds collected, and
                            (6) An appeals or petition process.
                       E.   As established by local ordinance or special election or petition, the local government shall
                            have responsibility for implementing all aspects of the utility including long range planning,
                            plan implementation, capital improvements, maintenance of stomwater facilities, determination
                            of charges, billing, and hearing of appeals and petitions. The local government also will have
                            responsibility for providing staff support for utility implementation.
                       F.   With the respect to new stormwater management facilities constructed by private developers,
                            the local government shall develop criteria for use in determining whether these will be
                            maintained by the utility or by the facility owner. Such criteria may include whether the
                            facility has been designed pfimarily to serve residential users and whether it has been designed
                            pfimarily for purposes of stormwater management. In situations where it is determined that
                            public maintenance is not preferable, standards shall be developed to ensure that inspection of


                                                                      32









                                 facilities occurs annually and that facilities are maintained as needed.
                            G.   The use of charges is limited to those purposes for which the utility has been established,
                                 including but not limited to: planning; acquisition of interests in land including easements;
                                 design and construction of facilities; maintenance of the stormwater system; billing and
                                 administration; and water quantity and water quality management, including monitoring,
                                 surveillance, private maintenance inspection, construction inspection, and other activities which
                                 are reasonably required.


                        72-311.  Plan Review and Lispector Certification Programs.
                            A.   The Commission shall require that local governments which request delegation of stormwater

                        72-312.  Review and Enforcement Requirements.
                            A.   Items listed in this section are activities by the Commission in the event the Commission serves
                                 as the UnPlerntnting agency. When the Commission is requested to assist the implementing
                                 agency, these are suggestions the Commission may submit to the implementing agency.
                            B.   The person responsible for the land disturbing activity shall notify the appropriate inspection
                                 agency before initiation of construction and upon project completion when a final inspection
                                 will be conducted to ensure compliance with the approved stormwater management and
                                 sediment control plan.
                            C.   The person responsible for the land disturbing activity shall, if required by the implementing
                                 agency during the plan approval process, submit "As Built or Record Document" plans. In


                                                                            33









                           addition, the person responsible for the land disturbing activity may be required to submit
                           written certification from the professional engineer, landscape architect, or Tier B land
                           surveyor responsible for the field supervision of the land disturbing activity that the land
                           disturbing activity was accomplished according to the approved stormwater management and
                           sediment control plan or approved changes.
                      D.   The responsible inspection agency shall, for inspection purposes, do all of the following items:
                           (1) Ensure that the approved stormwater management and sediment control plans are on the
                               project site and are complied with;
                           (2) Ensure that every active site is inspected for compliance with the approved plan on a
                               regular basis;

                               violations are observed, describing the:
                               (a) Nature of the violation;
                               (b) Required corrective action; and
                               (c) Time period for violation correction.
                      E.   The Commission may investigate complaints or refer any complaint received to the local
                           inspection agency if the activity is located in a jurisdiction that has received delegation of
                           inspections during construction and maintenance inspections. In conjunction with a referral,
                           the Commission may also initiate an on-site investigation after notification of the local
                           inspection agency in order to properly evaluate the complaint. The Commission shall make
                           recommendations on enforcement action when appropriate, and notify the local implementing
                           agency in a timely manner of any recommendations.
                      F.   The Commission, at its discretion and upon notification to the person responsible for the land
                           disturbing activity may visit any site to determine the adequacy of stormwater mana ement and
                           sediment control practices. In the event that the Commission conducts site inspection, the
                           appropriate inspection agency shall be notified of the inspection. The appropriate inspection
                           agency shall establish a tune frame to obtain site compliance. Tins notification shall, in no
                           way limit the right to the Commission to take action subsequent to any provision of these
                           regulations or Chapter. Formal procedures for interaction between the Commission and the
                           appropriate inspection agency on-site inspection and referral will be developed on an individual
                           basis.

                      G.   The appropriate plan approval agency may require a revision to the approved plans as
                           necessary due to differing site conditions. The appropriate plan approval agency shall establish
                           guidelines to facilitate the processing of revised plans where field conditions necessitate plan
                           modification. Where changes to the approved plan are necessary those changes shall be in
                           accordance to the following:
                           (1) Major changes to approved stormwater mana ement and sediment control plans, such as
                               the addition or deletion of a sediment basin, shall be submitted by the applicant to the
                               appropriate plan approval agency for review and approval.
                           (2) Minor changes to stormwater management and sediment control plans may be made in the
                               field review report. The appropriate inspection agency shall develop a fist of allowable
                               field modifications for use by the construction inspector.
                      H. Stormwater management construction shall have inspections accomplished as needed.



                                                                      34








                         I.   The agency responsible for construction inspection may, in addition to local enforcement

                           than one thousand dollars. No penalty may be assessed until the person alleged to be in
                           violation has been notified of the violation. Each day of a violation constitutes a separate
                           violation.
                       B.  The implementirig agency shall determine the amount of the civil penalty to be assessed under
                           this section for violations under its jurisdiction. It shall make written demand for payment
                           upon the person responsible for the violation and set forth in detail the violation for which the
                           penalty has been invoked. If payment is not received or equitable settlement reached within
                           thirty days after demand for payment is made, a civil action may be filed in the circuit court in
                           the county in which the violation is alleged to have occurred to recover the amount of the
                           penalty. If the implementing agency is the commission, the action must be brought in the
                           name of the State. Local governments shall refer the matters under their jurisdiction to their
                           respective attorneys for the institution of a civil action in the name of the local government in
                           the circuit court in the county in which the violation is alleged to have occurred for recovery
                           of the penalty.

                            XIII. Stormwater Management Guidelines (Page 111-74)


                       Most land disturbing activities in South Carolina must comply with the requirements and applicable
                       regulations of the Erosion and Sediment Reduction Act of 1983 (48-18-10, et. seq.), or the Stormwater
                       Management and Sediment Reduction Act of 1991 (48-14-10, et. seq.). The final regulations, effective
                       on June 26, 1992, pursuant to the Stormwater Management and Sediment Reduction Act of 1991,
                       establish the procedure and minimum standards for a statewide stormwater program. Section R.72-
                       304F of the regulations states that "the S.C. Coastal Council (now known as the Office of Ocean and
                       Coastal Resource Management (OCRM , in coordination with the Commission, will serve as the
                       implementing agency for these regulations in the jurisdictions of the local governments which do not
                       seek delegation of program elements in the counties of Beaufort, Berkeley, Charleston, Colleton,
                       Dorchester, Georgetown, Horry and Jasper." In addition, Section R.72-307C(5)(g) states that "For
                       activities in the eight coastal counties, additional water quality requirements may be imposed to comply
                       with the S.C. Coastal Council (OCRM Stormwater Management Guidelines. If conflicting
                       requirements exist for activities in the eight coastal counties, the S.C. Coastal Council (OCRM
                       guidelines will apply."


                       Pursuant to the Coastal Zone Management Act, the Coastal Council (OCRM is responsible for
                       protecting the environmentally sensitive areas of our coast. While the regulations of the Stormwater
                       Management and Sediment Reduction Act adequately address most nonpoint source pollution problems,
                       the need exists for establishing additional criteria to protect sensitive coastal waters.


                       A.   Stormwater Runoff Storage Requirements
                            The regulations of the Stormwater Management and Sediment Reduction Act require that
                            "permanent water quality ponds having a permanent pool shall be designed to store and release the
                            first 1/2 inch of runoff from the site over a 24-hour period. The storage volume shall be designed
                            to accommodate, at least, 1/2 inch of runoff from the entire site." For all projects, regardless of
                            size, which are located within one-half (1/2) mile of a receiving waterbody in the coastal zone, this
                            criteria shall be storage of the first 112 inch of runoff from the entire site or storage of the first one
                            (1) inch of runoff from the built-upon portion of the property, whichever is greater. Storage may
                            be accomplished through retention, detention or infiltration systems, as appropriate for the specific
                            site. In addition, for those projects which are located within 1,000 (one thousand) feet of shellfish
                            beds, the first one and one half (1 1/2) inches of runoff from the built-upon portion of the property
                            must be retained on site.



                            Receiving waterbodies include all regularly tidally influenced salt and freshwater marsh areas, all
                            lakes or ponds which are used primarily for public recreation or a public drinking water supply,
                            and other water bodies within the coastal zone, excluding wetlands, swamps, ditches and
                            stormwater management ponds which are not contiguous via an outfall or similar structure with a
                            tidal water body.




                                                                             43









                  B.  Project Size Requiring Stormwater Management Permits
                      Section R.72-305B(l) states that "for land disturbing activities involving two (2) acres or less of
                      actual land disturbance which are not part of a larger common plan of development or sale, the
                      person responsible for the land disturbing activity shall submit a simplified stormwater mana ement
                      and sediment control plan meeting the requirements of R.72-307H. This plan does not require
                      preparation or certification by the designers specified in R.72-305H and R.72-3051." Due to the
                      potentially damaging effect of certain projects of less than two (2) acres of land disturbance,
                      stormwater management and sediment reduction plan submittal and regulatory approval shall be
                      required for those smaller projects located within 1/2 mile of a receiving waterbody. Single family
                      homes that are not part of a subdivision development are exempt from this requirement.


                 C.   Stormwater Management Requirements for Bridge Runoff
                      The following is the criteria used to address stormwater management for bridges traversing
                      saltwater and/or critical areas.

                      (1) No treatment is necessary for runoff from bridge surfaces spanning SB or SA waters. This
                          runoff can be discharged through scupper drains directly into surface waters. However, the
                          use of scupper drains should be limited as much as feasibly possible.
                      (2) If the receiving water is either ORW or SFH then the stormwater mana ement requirements
                          shall be based on projected traffic volumes and the presence of any nearby shellfish beds. The
                          following matrix lists the necessary treatment practices over the different classes of receiving
                          waters.

                      (3) The Average Daily Traffic Volume (ADT) is based upon the design carrying capacity of the
                          bridge.


                          Water Quality Class                                   Average Daily Traffic Volume (ADT)
                                                                                      0-30,000    G.T. 30,000
                          ORW (within 1000 ft of shellfish beds)
                          ORW (not within 1000 ft of shellfish beds)
                          SFH (within 1000 ft of shellfish beds)
                          SFH (not within 1000 ft of shellfish beds)
                          SA
                          SB

                      The first one (1) inch of runoff from the bridge surface must be collected and routed to an
                 appropriate stormwater management system or routed so that maximum overland flow occurs
                 encouraging exfUtration before reaching the receiving body. Penodic vacuuming of the bridge surface
                 should be considered.

                 ** A stormwater management plan must be implemented which may require the overtreatinent of runoff
                 from associated roadways to compensate for the lack of direct U=tment of runoff from the bridge
                 surface itself. Periodic vacuuming should be considered. The use of scupper drains should be limited as
                 much as feasibly possible.
                   No treatnient is required. The use of scupper drains should be limited as much as feasibly possible.








                                                                  44









                     D.   Golf Courses Adjacent to Receiving Waterbodies
                          Golf course construction and maintenance practices result in the potential for significant negative
                          impacts from the runoff of sediments, pesticides, herbicides and other pollutants. For this reason,
                          when golf courses are constructed adjacent to receiving waterbodies then the following practices
                          are to be incorporated.
                          (1) Minimum setbacks from the receiving waterbody of 20 feet for all manicured portions of the
                              golf course (fairways, greens and tees) are required unless other acceptable management
                              techniques are approved and implemented to mitigate any adverse impacts.
                          (2) All drainage from greens and tees must be muted to interior lagoons or an equivalent
                              storrnwater mana em nt system.
                          (3) To prevent the conversion of the stormwater system to critical area and to maintain positive
                              drainage at high tides, all outfalls from the lagoon system must be located at an elevation
                              above the critical area (if the discharge is to critical area) AND above the normal water
                              elevation a distance to allow for storage of the first one inch of runoff. The volume which
                              must be stored shall be calculated by multiplying the area of all the greens and tees by one
                              inch. (Previously constructed stormwater mana ement systems which meet all current and
                              future storage requirements will not be required to modify outfalls.)
                          (4) No greens or tees shall be located on marsh hummocks or islands unless all drainage can be
                              conveyed to the interior lagoon system or to an equivalent onsite stormwater management
                              system.
                          (5) Stormwater impacts to freshwater wetlands shall be limited by providing mininium 20 foot
                              buffers, or an accepted alternative, between manicured areas (fairways, greens and tees) and
                              the wetlands. This minimum buffer must be increased if land application of treated effluent is
                              utilized in the area.

                          (6) An integrated pest mana ement system designed in accordance with current best technology
                              practices must be employed on the course to limit the application of chemicals which, if over
                              applied, may leach into the ground and adjacent surface waters.
                          (7) In accordance with S.C. Department of Health and Environmental Control requirements, a two
                              (2) foot separation must be maintained between the surface of the golf course and the ground
                              water table where spray effluent is applied.
                          (8) The normal ground water elevation must be established by a registered engineer or soil
                              scientist.
                          (9) All pmJects which are within 1000 feet of shellfish beds must retain the first 1 1/2 -inches of
                              runoff as otherwise described in item A above.
                          (IO)If spray effluent or chemicals are applied to the turf via the irrigation system, all spray heads
                              must be located and set so as to prevent any aerosols from reaching adjacent critical areas.


                     E. Nfines and Landfills

                          Due to the significant amount of land disturbance involved in the construction of mines and
                          landfills, these types of operations need to strictly adhere to sediment/emsion control requirements
                          particularly when they are located near coastal waterways. When mining or landfill projects are
                          located within 1/2 mile of receiving waterbodies, pumping of ground water from sediment basins
                          must be done with floating intakes only. Pumping of these basins must cease whenever the water
                          levels come to within two (2) feet of the pond bottom. In addition, landfill planning must be
                          designed on a comprehensive site basis for stormwater management and sediment/erosion control to
                          include mana ement practices for each separate cell as it is phased into the landfill.


                                                                        45

                                                            PREFACE





           The CWA provides that storm water discharges associated with industrial activity from a point source
           (including discharges through a municipal separate storm sewer system) to waters of the United States
           are unlawful, unless authorized by a National Pollutant Discharge Elimination System (NPDES) permit.
           The terms "storm water discharge associated with industrial activity", "point source" and "waters of the
           United States* are critical to determining whether a facility is subject to this requirement. Complete
           definitions of these terms are found in the definition section (Part IX) of this permit.










































                                                             52











                      Part 1. COVERAGE UNDER THIS PEP.NM
                         A. Pennit Area. The permit covers all areas of South Carolina.

                         B. Elieibility.
                              1.   This permit may authorize all discharges of storm water associated with industrial activity
                                   from construction sites, (by present EPA regulation this is sites or common plans of
                                   development or sale that will result in the disturbance of five or more acres total land area,
                                   however this may be reduced to less than five acres'), (henceforth referred to as storm
                                   water discharges from construction activities) occurring after the effective date of this
                                   permit (including discharges occurring after the effective date of this permit where the
                                   construction activity was initiated before the effective date of this permit), except for
                                   discharges identified under paragraph I.B.3.
                              2.   This permit may only authorize a storm water discharge associated with industrial activity
                                   from a construction site that is mixed with a storm water discharge from an industrial
                                   source other than construction, where:
                                   a.    the industrial source other than construction is located on the same site as the
                                         construction activity;
                                   b.    storm water discharges associated with industrial activity from the areas of the site
                                         where construction activities are occurring are in compliance with the terms of this
                                         permit; and
                                   c.    storm water discharges associated with industrial activity from the areas of the site
                                         where industrial activity other than construction are occurring (including storm water
                                         discharges from dedicated asphalt plants and dedicated concrete plants) are covered by
                                         a different NPDES general permit or individual permit authorizing such discharges.
                              3. Limitations on Coveraee IMe following storm water discharges from construction sites
                                   are not authorized by this permit:
                                   a.    storm water discharges associated with industrial activity that originate from the site
                                         after construction activities have been completed and the site has undergone final
                                         stabilization.
                                   b.    discharges that are mixed with sources of non-storm water other than discharges
                                         which are identified in Part HLA of this permit and which are in compliance with Part
                                         IV.D.5 (non-storm water discharges) of this permit.
                                   c.    storm water discharges associated with industrial activity that are subject to an existing
                                         NPDES individual or general permit or which are issued a permit in accordance with
                                         paragraph VLL (requiring an individual permit or an alternative general permit) of
                                         this permit. Such discharges may be authorized under this permit after an existing
                                         permit expires provided the existing permit did not establish numeric limitations for
                                         such discharges;
                                   d.    storm water discharges from construction sites that the Department has determined to
                                         be or may reasonably be expected to be contributing to a violation of a water quality
                                         standard; and
                                   e.    storm water discharges from construction sites if the discharge or the clearing
                                         activities are likely to adversely effect a listed endangered or threatened species or its
                                         critical habitat.







                         On June 4, 1992, the United States Court of Appeals for the Ninth Circuit remanded the exemption for
                         construction sites of less than five acres to the EPA for further rulemaking. (Nos. 90-70671 and 91-
                         70200). When this issue is resolved, this permit will be administratively modified without further public
                         notice to be in compliance with the final EPA regulation.

                                                                           53











                     C. Authorization.
                          1.  A discharger must submit a Notice of Intent (NOI) in accordance with the requirements of
                              Part II of this permit, using a NOI form provided by the Department (or a photocopy
                              thereof), in order for storm water discharges from construction sites to be authorized to
                              discharge under this general permit.
                         2.   All contractors and subcontractors of the owner/operator whose activities at the site may
                              impact storm water discharges or controls at the site along the duration of the project, shall
                              sip a copy of the certification statement given below:


                                   "I certify by my signature below that I accept the terms and conditions of the
                                   Storm Water Pollution Prevention Plan (SWPPP) as required by the general
                                   National Pollutant Discharge Elimination System (NPDES permit number
                                   SCR100000) issued to the owner/operator of the construction activity for which I
                                   have been contracted to perform construction related professional services.
                                   Further, by my signature below, I understand that I am becoming a co-permittee
                                   with the owner/operator and other contractors that have become co-permines to the
                                   general NPDES permit issued to the owner/operator of the facility for which I have
                                   been contracted to perform professional construction services. As a co-permittee, I
                                   understand that I, and my company, as the case may be, are legally accountable to
                                   the SC Department of Health and Environmental Control (DHEC), under the
                                   authorities of the CWA and the SC Pollution Control Act, to ensure compliance
                                   with the terms and conditions of the SWPPP. I also understand that DHEC
                                   enforcement actions may be taken against any specific co-permittee or combination
                                   of co-permittees, if the terms and conditions of the SWPP are not met. Therefore,
                                   having understood the above information, I am signing this certification and am
                                   receiving co-permittee status to the aforementioned general NPDES permit." The
                                   date of the signature, the tide of the person providing the signature, and the name,
                                   address, and telephone number of the contracted firm, shall also be provided. In
                                   the event the SWPPP is amended by the owner, such amendments should be
                                   incorporated to the plan and the contractors and subcontractors should acknowledge
                                   by signature.
                              The signatory requirements of 40 CFR 122.22, as provided in Part VI.G of this permit are
                              applicable to each contracted entity that must sip the contractor's certification statement.
                              Upon signing the certification, the contractor is a co-permittee and becomes accountable to
                              the Department to ensure the terms and conditions of this permit are implemented. All co-
                              permintes are subject to Department enforcement actions if permit conditions are not met.
                              Enforcement actions may be taken against any specific co-permittee or combination of co-
                              permiftees, with consideration given to the party responsible for the violation. The
                              owner/operator submitting the NOI shall retain all contractor certifications for at least three
                              years after a contractor has completed work at the site. Copies of all contractor
                              certifications and a copy of this permit shall be retained on the site of the construction
                              activity. The owner/operator of the facility covered by this permit shall make all contractor
                              certifications available upon request to the Department.
                         3.   Unless notified by the Department to the contrary, dischargers who submit an NOI in
                              accordance with the requirements of this permit are authorized to discharge storm water
                              from construction sites under the terms and conditions of this permit 48 hours after the date

                               an individual NPDES permit, the Department shall notify the discharger in writing that a
                               permit application is required. This notification shall include a brief statement of the
                               reasons for this decision, an application form, a statement setting a deadline for the
                               discharger to file the application, and a statement that on the effective date of the individual
                               NPDES permit or the alternative general permit as it applies to the individual permittee,
                               coverage under this general permit shall automatically terminate. Applications shall be
                               submitted to the Department at the address indicated in Part V.C of this permit. The
                               Department may grant additional time to submit the application upon request of the
                               applicant. If a discharger fails to submit in a timely manner an individual NPDES permit
                               application as required by the Department under this paragraph, then the applicability of
                               this permit to the individual NPDES permittee is automatically terminated at the end of the
                               day specified by the Department for application submittal.
                          2.   Any discharger authorized by this permit may request to be excluded from the coverage of
                               this permit by applying for an individual permit. In such cases, the permittee shall submit
                               an individual application in accordance with the requirements of 40 CFR 122.26(c)(1)(ii),
                               with reasons supporting the request, to the Department at the address in Part V.C of this
                               permit. The request may be granted by issuance of an individual permit or an alternative
                               general permit if the reasons cited by the permittee are adequate to support the request.
                          3.   When an individual NPDES permit is issued to a discharger otherwise subject to this
                               permit, or the discharger is authorized to discharge under an alternative NPDES general
                               permit, the applicability of this permit to the individual NPDES permittee is automatically
                               terminated on the effective date of the individual permit or the date of authorization of
                               coverage under the alternative general permit, whichever the case may be. When an
                               individual NPDES permit is denied to a discharger otherwise subject to this permit, or the
                               discharger is denied for coverage under an alternative NPDES general permit, the
                               applicability of this permit to the individual NPDES permittee remains in effect, unless
                               otherwise specified by the Department.

                                       FOR CONTROL OF SEDUMNT IN SOUTH CAROLINA3

                  Introduction
                  Simulations using a modified version of SEDIMOT Il estimated the effectiveness of structures for sediment
                  control in four different physiographic regions of South Carolina. For the purposes of this work, we separated
                  the state into four (4) major land resource areas - piedmont, sand hills, coastal plain, and tidal area. Treatments
                  also included multiple watershed sizes, land uses, and soil textures in each land resource area. The evaluation
                  included a wide range of slope lengths, slopes, pond dimensions, watershed shapes, as well as other factors that
                  are required for specific structures. Impacts of various controls on downstream sediment load were evaluated
                  using generated hydrographs and sedimentgraphs from watersheds. Design aids in the form of graphs were
                  developed to simplify design for typical conditions and avoid simple rule-of-thumb design estimates. These
                  design aids are a compromise between detailed simulations and simple rules-of-thumb.

                  Background
                  Recently regulations have been instituted that require control of stormwater runoff and sediment discharge.
                  Standard techniques are recommended for runoff, but methods for designing structures for sediment control are
                  lacking.
                  The described work includes estimation of performance of sediment detention ponds, filter fences, and rock
                  ditch checks. The performance of each control was simulated using a modified version of SEDIMOT 11 with
                  South Carolina's specific conditions and compared with existing regulations in the state. From these simulations,
                  design aids were developed that are consistent with the sediment performance standards required by the state
                  regulations.
                  Effectiveness of control is commonly determined by either a water quality design standard or a performance
                  standard. For sediment control, a water quality performance standard dictates a maximum acceptable level of
                  sediment in the effluent. The control is designed such that this concentration is not exceeded. On the other hand,
                  a water quality design standard establishes a standard pond design based on a given drainage area or similar
                  criterion. There are obvious benefits associated with each method. Performance standards offer site specific
                  water quality control, but require considerable on-site collection of information for design purposes and are
                  more difficult to review. Structures designed for performance standards have a higher design cost than
                  structures designed for water quality design standards since estimation of effluent concentration is difficult and
                  requires complex calculations. However construction costs tend to be considerably less, since design standards
                  are inherently conservative. Design standards, on the other hand, are more easily employed and complied with.
                  A preferable alternative to these methods is to provide a design procedure that meets a performance criteria
                  without requiring excessive design costs. To achieve this, the design is typically expected to be slightly
                  conservative, but considerably less conservative than if developed from a design standard.
                  A typical approach under the performance philosophy is to size a control to meet a water quality standard such
                  as a total suspended solids (TSS) or settleable solids (SS) standard. Trapping efficiency can also be used, but
                  this fails to account for incoming sediment concentration. Specific requirements for permanent stormwater

               management and sediment control plan approval shown in the S.C. Storinwater Management and Sediment
               Reduction Regulations include discharge rates and hydrographs; for stormwater runoff. Additionally, sediment
               basins or other practices must be designed to meet a removal efficiency of 80 percent suspended solids or 0.5
               ml/l peak settleable solids concentration from a 10-yr, 24-hr design storm.

               Potential Benefts
               The intent of this work was to develop area specific design methods that give reasonable assurance that effluent
               meets desired sediment performance standards without the lengthy design process typically associated with
               designs developed to meet a performance standard. This approach benefits regulatory agencies and developers
               because the time required for design of controls for "typical" situations would be straightforward and
               minimized. Plan reviewers do not have to labor through detailed calculations. The use of area specific design
               methods provides a means of achieving sediment control without the steep learning curve associated with
               simulation techniques. This allows engineers to gradually gain experience and expertise in design of sediment
               controls. As reviewers and planners become more experienced with the procedures, they may move to modeling
               techniques or other methods. (For large scale developments or in sensitive areas, it is still anticipated that site
               specific data and other procedures such as modeling be used for detailed evaluation of sediment controls.)
               Adoption of area specific design techniques among state and local agencies helps to standardize use of the
               practices, reduce confusion, and promote adoption of design techniques.

               Methodology
               The project began with site visits at numerous locations in each of the land resource areas of the state in order
               to see innovative methods, as well as areas needing improvement. Evaluation of existing modeling capabilities
               led to major revisions in the SEDIMOT 11 model to allow evaluation of a wide range of sediment control
               technologies in a seamless manner. These modifications present South Carolina with the opportunity to have a
               major new tool in the analysis and design of stormwater and sedimetit control structures. Input data bases were
               generated for all major land resource regions and results from almost half a million runs of the model were used
               to develop the simple design aids.
               The tour of South Carolina construction sites revealed that channel erosion was a significant problem in many
               watersheds, indicating a need for adding a channel erosion component to the model. The existing routine in
               SEDIMOT U allows only for deposition in channels, no erosion.
               The tour of South Carolina also showed that filter fences were often not put on the contour, but were placed to
               allow flow to move along the fence to a low spot. This flow frequently caused significant erosion along the
               fence and undercutting of the fence, rnskkin the fence ineffective. It was postulated that a saw tooth type
               arrangement on the fence would prevent this erosion, but no method was available to predict the effectiveness of
               the fence under this condition. This required that a method be developed to determine the location of points
               where flow would move through the fence.
               After investigating possibilities for modifying the existing routines in SEDIMOT II, it was determined that the
               inaccuracies in hydraulic routing when the pond routine is used for small structures and the lack of adequate
               sedimentation routines in the check dam routine meant that a major program modification was necessary.
               Because of the availability of a new hydraulic routine that is accurate over a wide range of structural sizes and
               types, it seemed prudent to make such a modification. The process used was to:

                ï¿½       Develop a common model for reservoir routing which utilizes continuous functions for discharge and
                        stage storage rather than discrete stage points.
                ï¿½       Develop physically based and tested methodologies for predicting stage discharge relationships for
                        commonly used sediment control structures.
                0       Combine these routines with the CSTRS routines used in SEDIMOT II.
                ï¿½       Modify the model to include channel erosion.
                ï¿½       Evaluate the effects of a saw tooth arrangement on filter fence effectiveness.

               Each of these tasks has been accomplished and the results are a series of graphs that can be used as an aid for
               designing sediment control structures. It should be recognized that aids such as these are developed for typical


                                                                         90







                  conditions. Other methods should be used if the situation is environmentally sensitive or hazardous. In all
                  cases, good engineering judgement should be considered as an essential ingredient in design.

                  Design Aids
                  Each of the design aids will be briefly described and then examples will be used to demonstrate their use in
                  realistic problems. The first aid (Figure 1) plots particle settling velocity as a function of eroded particle
                  diameter. Each of the structures requires use of a reference settling velocity. The diameter that is referred to
                  as D,, was chosen for the reference diameter. This diameter corresponds to a point on the eroded particle size
                  distribution curve such that 15% of the particles (by weight) are equal to or smaller than this size. Personnel
                  from the former S.C. Land Resources Commission have previously developed estimated eroded size
                  distributions for South Carolina soils. The procedure used the primary particle size information reported by the
                  Soil Conservation Service as part of county soil surveys. The information is now available from S. C.
                  Department of Health and Environmental Control. By plotting "fi-action finer than" versus "diameter," D,, can
                  be read. Once D15 is found, settling velocity can be read directly from Figure 1. Figure 2 plots the ratio
                  VAV15 versus percentage of trapping efficiency. For ponds, the ratio is defined by
                                                   Rado  = qP0
                                                            A Vis


                  where qP, is peak outflow rate from the pond in ch, A is the surface area of the pond at the riser crest in acres,
                  and V,, is settling velocity, in fps, of the characteristic eroded particle corresponding to D,,. Upper limits on
                  site conditions for ponds are included with Figure 2.
                  Two curves are presented. The curve shown as Figure 2a is for soils including Piedmont, Sandhill, Coastal,
                  and Tidal area soils, except as noted subsequently. For the Piedmont, Coastal, and Tidal areas, soils are
                  classed as either coarse (sandy loam), medium (silt loam), or fine (clay loam). Sandhill soils include coarse
                  (sand), medium (sandy loam), and fine (silt loam) because of the prevalent textures in this region. These
                  classifications are summarized in Table 1. The line shown as Figure 2b is for tidal soils (sands and sandy
                  loams that are classified in hydrologic soil group D because of high water table). The ratio should be less than
                  or equal to the curve value at any given trapping efficiency. For example at 80% trapping efficiency, the ratio
                  is equal to 2.2E5 for most soils as shown in Figure 2a. If the ratio c6/AVs intersects the curve at a point
                  having a trapping efficiency less than the desired value, the design is inadequate and must be revised. Ratios
                  above the design curves are not recommended for any of the design aids.
                  The next design aid (Figure 3) is for rock ditch checks. Again there is a ratio plotted versus trapping
                  efficiency. For rock ditch checks the ratio is calculated as
                                                 Ratio = SqO-4                                                                     (2)
                                                            a VIS

                  where S is the channel slope in percent, q is flow through the check in cfs/ft, V15 is the settling velocity, in fps,
                  of the eroded D1. size particle in mm, and a and b are coefficients. Figure 3 also contains upper limits for site
                  conditions appropriate for the design aid.

               The ratio is calculated using the curves developed in Haan et al. (1994)4 to obtain the coefficients a and b. ne
               three plots shown as Figure 3a, 3b, and 3c correspond to fine, medium, and coarse textures, respectively.
               Please refer to Table I for determination of which line to use for a particular soil. As indicated by the note in
               the gray area above the lines, values of the ratio in Figure 3 should be equal to or less than the curve values.
               Ile design aid shown as Figure 4 corresponds to silt fence placed in an area downslope from a disturbed area
               where it serves to retard flow and cause settling. Two conditions must be met in order to have a satisfactory
               design.
                 1.    Trapping efficiency must meet the desired level of control.
                 2.    Overtopping of the structure must not occur, since failure is likely if it does occur.
               As with any structure, the designer should recognize that longterm maintenance is necessary. The fence design
               aid contains a single line that is appropriate for all soil textures as shown in Figure 4. Again the ratio is plotted
               versus trapping efficiency. For the silt fence, the ratio is calculated as

                                            Rado        SP"                                                                 (3)

               where qP. is peak outflow through the fence in cfs, V,5 is settling velocity, in fps, of the eroded Dt. size
               particle, and P,. is the potential ponding area upslope of the fence in ft. Figure 4 includes a listing of upper
               limits for the site conditions for the fence design aid.
               The ponded area can be estimated by reducing the height of the fence by 1.0 ft (to allow for burying 0.5 ft and
               0.5 ft for freeboard). Use the remaining height to find the distance of a horizontal line extending from the
               fence top to its intersection with the ground surface up slope of the fence (should be equal to the ground slope
               times the fence height). Multiply this distance by the available width for ponding to obtain the potential ponding
               area. As for other structures, the final filter fence ratio value should be less than or equal to the line value for
               a specified trapping efficiency.

               Esfimadng Vi,
               A common feature of each of the design aids is that a characteristic settling velocity for the eroded soil must be
               obtained. For these design aids, the characteristic settling velocity required corresponds to an eroded size such
               that 15 % of the sediment has particles smaller than the size specified. A diskette containing acceptable eroded
               size distributions for South Carolina soils is available from the South Carolina Department of Health and
               Environmental Control. The user should recognize that eroded size distributions used in sediment control
               design are frequently quite different from primary size distributions that are often determined for other
               construction purposes. The user should note that DO is often smaller for coarse textured (more sandy) because
               of the reduced clay content and the lack of aggregation.

               Example Problems
               The example problems serve to Mush-ate the use of the design aids for calculation of trapping efficiency for
               various types of structures. Basic soils, hydrologic, and hydraulic information are combined. Methods as
               required by Standards for Stormwater Management and Sediment Reduction (72-300) may be used to estimate
               the peak flows. Site specific soils information can generally be found from county soil surveys. Hydraulic
               information is obtained by combining site and structural information.
               In all cases, a ratio is calculated. The ratio is used to locate the point on a turning line for the specified
               conditions and structure. Trapping efficiency is then found by turning to the x-axis and estimating trapping
               efficiency. The design aids are intended to be slightly conservative, but use of the design aids should not
               override use of good engineering judgement. Questionable results should be investigated by the engineer. In
               addition, the engineer should consider installation and maintenance of all structures. For example, it may be

                    The user should recognize that the intent of the design aids is to provide an estimate of trapping efficiencies for
                    "typical" structures. Extreme or critical situations necessitate that more detailed analyses be conducted. For
                    example, sensitive areas in steep terrain would be an example of an extreme situation. Additionally, it is not
                    the intent of this document to present detailed descriptions of hydrologic or hydraulic methods.
                    Design techniques can best be illustrated by following the steps shown in the following examples.

                    ExamWe Problem 1 - Sediment Pond.
                    A sediment pond is to be constructed on a 30-acre commercial site in Richland County, SC. The following
                    information is available for the site based on soil, hydrologic, and hydraulic conditions.
                              The eroded size distribution is for a coarse soil (Pelion and Fuquay mix) with D,, equal to 0.024 nun.
                              Peak outflow from the pond cannot exceed 11.2 cfs.
                              Allowable surface area of the pond at the riser crest is 1.67 ac.
                    Determine whether the sediment pond is adequately sized for satisfactory trapping.

                    Solution:

                    Steps
                      1 .     Go to Figure I with D1, = 0.024 min and determine settling velocity V15 = 0.001 fps.
                      2.      Calculate the ratio VAV,,= 11.2/(1.67)(0.001) = 6700 = 6.7113
                      3.      Enter Figure 2a on y-axis with ratio = 6.7113, go to line and turn to x-axis to read trapping efficiency.
                      4.      Trapping efficiency is approximately equal to 92%, therefore okay.

                    Example Problem 2 - Sediment Pond.
                    A sediment pond is to be constructed in a tidal area having a high water table. The following information is
                    available for the site near the coast.

                              The eroded size distribution is for a coarse soil with Dts equal to 0.05
                              Peak outflow from the pond is 10 cis.
                              Allowable surface area of the pond is 0.25 ac.
                    Determine whether the structure will provide at least 80% trapping.

                    Solution:

                    Stevs
                      1.      Go to Figure 1 with Dt, = 0.05 min and determine settling velocity V1. = 0.004 fps.
                      2.      Calculate the ratio qWAV,,= lo/(0.25)(0.004) = 10,000 = I.OE4
                      3.      Enter Figure 2b (since high water table) on y-axis with ratio = 1.0134, go to line and turn to x-axis to
                              read trapping efficiency.
                      4.      Trapping efficiency is approximately equal to 77%, therefore a larger pond is required if it is desired to
                              have a trapping efficiency of at least 80%.
                      5.      Assume that surface area can be increased to 0.67 ac, calculate the ratio qWAVI,= 10/(0.67)(0.004)
                              3700 = 3.7133.
                      6.      Reading the trapping efficiency from Figure 2b using this value yields a trapping efficiency of 81 %,
                              which is okay. (Note: If there had been no high water table, Figure 2a would be used, and the
                              smaller pond area would be sufficient.)






                                                                                93









               Example Problem 3 - Rock Ditch Check.
               Estimate the trapping efficiency of a rock ditch check to be installed in a Piedmont channel draining a clay loam
               soil. The following information is available based on soil, hydrologic, and hydraulic conditions.
                      The eroded size distribution is for a fine soil with DO equal to 0.0042 mm.
                      Peak outflow from the ditch check is 0.21 lcfs with an average width (perpendicular to flow) of 7.4 ft
                      and a flow length through the check of 9 ft (refer to Haan et al., 1994, page 151 for procedures to
                      calculate flow through a ditch check).

                      Rock diameter is 0. 10 ft.

                      Slope of the channel is 0.5%.

               Solution:

               SteIDS

               1.     Go to Figure I with DI, = 0.0042 nun and determine settling velocity V15 = 3E-5 fps.
               2.     Before proceeding further, the flow rate must be converted to a flow per foot width. Thus divide
                      0.211 cfs by the width of 7.4 ft to obtain a q = 0.028 cfs/ft.
                      Appropriate values of the coefficients a and b can be obtained from Haan, et al. (1994) based on the
                      rock diameter and the average flow length through the check. For this example, the appropriate values
                      can be read using the rock diameter equal to 0.03 in and flow length equal to 9 ft to obtain a = 3.05
                      and b = 0.66.
                      Substitute all values and calculate the ratio
                             Sq(")/aV. = (0.5)(0.028(111) )/(3.05)(3E-5) = 1620 = 1.62E3
               I      Enter Figure 3a (fine texture) on y-axis with ratio = 1.60, go to line and turn to x-axis to read
                      trapping efficiency.
               4.     Trapping efficiency is greater than 95 %, therefore okay.

               Example Problem 4 - Rock Ditch Check.
               A rock ditch check is to be installed at a Coastal Plains site having a sandy loam soil. For comparison,
               hydrologic and hydraulic conditions as used in Example Problem 3 will be used.
                      The eroded size distribution is for a coarse soil with Dt. equal to 0.04
                      Peak outflow from the ditch check is 0.21 lcfs with an average width (perpendicular to flow) of 7.4 ft
                      and a flow length through the check of 9 ft.

                      Rock diameter is 0.10 ft.

                      Slope of the channel is 0.5%.
               Determine whether the ditch check will exceed 80% trapping efficiency for the conditions indicated.

               Solution:

               Steps
               1 .    Go to Figure I with D,5 = 0.04 mm and determine settling velocity V. = 2.8E-3 fps.
               2.     Before proceeding further, the flow rate must be converted to a flow per foot width. Thus divide
                      0.211 cfs by the width of 7.4 ft to obtain a q = 0.028 cfs/ft.
                      Since the same conditions were used, values of the coefficients a and b are as found in Example
                      Problem 3 so that a = 3.05 and b = 0.66.
                      Substitute all values and calculate the ratio
                             Sq('-b)/aV,5 = (0.5)(0.028(1-0-0) )/(3.05)(2.8E-3) = 17
               3.     Enter Figure 3c (coarse texture) on y-axis with ratio = 17 and go to line. Note that since the value
                      falls BELOW the line, the trapping efficiency exceeds 95 %.
               4.     Trapping efficiency is greater than 95 %, therefore okay.




                                                                  94









                  Example Problem 5 - Rock Ditch Check.
                  A rock ditch check is to be installed in a channel draining highway construction on a sandy loam soil in the
                  Coastal Plains. The following information is available based on soil, hydrologic, and hydraulic conditions.
                           The eroded size distribution is for a coarse soil with DO equal to 0.04 mm.
                           Peak outflow from the ditch check is 2.0 cfs with an average width (perpendicular to flow) of 4.4 ft
                           and a flow length through the check of 9 ft.

                           Rock diameter is 0.10 ft.

                           Slope of the channel is 4.0%.
                  Determine the trapping efficiency under the specified conditions.

                  Solution:

                  Stevs
                   I.      Go to Figure I with D,_, = 0.04 mm and determine settling velocity V,, = 2.8E-3 fps.
                   2.      Before proceeding further, the flow rate must be converted to a flow per foot width. Thus divide 2.0
                           cfs by the width of 4.4 ft to obtain a q = 0.45 cfs/ft.
                           Appropriate values of the coefficients a and b can be obtained from Haan, et al. (1994) based on the
                           rock diameter and the average flow length through the check. For this example, the appropriate values
                           can be read using the rock diameter equal to 0.03 m and flow length equal to 9 ft to obtain a = 3.05
                           and b = 0.66. Substitute all values and calculate the ratio
                                   Sq('-b)/aV,5 = (4.0)(0.450-0-ft) )/(3.05)(2.8E-3) = 360
                   3.      Enter Figure 3c on y-axis with ratio = 360, go to line and turn to x-axis; to read trapping efficiency.
                   4.      Trapping efficiency is approximately 94%, therefore okay.

                  Example Problem 6 - Miter Fence at Toe of Slopg.
                  A wire-backed silt fence is to be built from fabric which is 3 ft wide. The installation is to be at the toe of a
                  slope which drains highway construction in the Piedmont. The following information is available based on soil,
                  hydrologic, and hydraulic conditions at the site.
                           The eroded size distribution is for a fine soil with DI., equal to 0.0042 mm.
                           Peak outflow from the up slope area is 1.9 cfs.
                           The potential area for impoundment up slope of the fence is 0. 116 ac. (5050 W).
                           Freeboard allowance and installation will reduce the usable height of the fence from 3 ft to 2 ft.
                           The potential length of filter fence along the toe of the slope is 60 ft.
                  Determine whether the fence will carry this flow with a trapping efficiency of at least 80% without overtopping.

                  Solution:

                  Ste s
                    .p
                   1.      Go to Figure I with DI, = 0.0042 mm, and determine settling velocity VI, = 3E-5 fps.
                   2.      Calculate the ratio qpjVP.= 1.9/(3E-5)(5050) = 12.5.
                   3.      Reading the trapping efficiency from Figure 4 with the ratio equal to 12.5 finds that the trapping
                           efficiency is approximately 55% - hence the fence is inadequate.










                                                                       95








              Example Problem 7 - Filter Fence at Toe of Slove.
              Reconsider the situation described in example problem 6 with the only difference being that the D,, is 0.04
              Determine whether the fence will carry this flow with a trapping efficiency of at least 80% without overtopping.

              Solution:

              ELeps
               1.     As seen previously, V,5 equals 2.813-3 fps for this size particle.
               2.     Calculate the ratio qpjV,P,.= 1.9/(2.BE-3)(5050) = 0.13
               3.     Reading the trapping efficiency from Figure 4 with the ratio equal to 0. 13 finds that the trapping
                      efficiency is approximately 82% - hence the fence is adequate from the standpoint of trapping
                      efficiency.
               4.     The length of fence required to pass the peak flow without overtopping can be found by comparing the
                      peak flow per foot width with the slurry flow rate of the fabric. Haan, et al. (1994, Table 9. 11 and
                      9.12) contains slurry flow rates for a variety of fabrics. A reasonable value for filter fence is 10
                      gpM/ft2.
               5.     Convert the peak flow to gpm so that
                               qP. = (1.9 W/sec)(7.48 gal/ft3)(60 sec/min) = 853 gpm
               6.     The required length of fabric to carry this flow can now be found by dividing the peak flow rate by the
                      effective height (2 ft since I ft is lost because of installation) and the slurry flow rate. Hence, the
                      length of fence required to carry the peak flow without overtopping is
                              L = 853/(2)(10) = 43 ft
                      Since 43 ft is less than the 60 ft available, the fence wHI perform adequately.
