Things You See In The Field Water Quality Regulations NPDES Phase I Requirements • NPDES requirements • Implemented and regulated by SCDHEC in SC • Required all construction sites disturbing ≥ 5 acres to obtain coverage to discharge stormwater. • Defined 11 categories of activity, including construction if disturbance of activity ≥ 5 acres than NPDES approval required. • Required all municipalities with populations equal to 100,000 or more to acquire coverage for Non Point Source discharge. Water Quality Regulations NPDES Phase II Requirements • Promulgated in 2003 • Required all construction sites disturbing 1-5 acres to acquire permit coverage under NPDES program. • Added 1-5 acres in Industrial activities and expanded upon the no exposure limitation from 1 group of activity to all 11 groups. • Required municipalities with populations between 10,000 and 100,000 to obtain NPDES Coverage. Water Quality Regulations NPDES Phase II Requirements • Second Permit Cycle Effective January 1, 2014. • Small MS4s must develop a program to cover the following minimum control measures: • Public education and outreach • Public participation/ involvement • Illicit discharge detection and elimination • Construction site runoff control • Post-construction site runoff control • Pollution prevention/ good housekeeping. Things You See In The Field Regulatory Connection • Areas Required for Review o SMS4s are required to review construction and redevelopment activities that discharge to their SMS4 system in the areas outlined in their initial certificate of coverage, and o In areas where the SMS4 has annexed or where the urbanized area has expanded based on the 2010 census. Regulatory Connection • Areas Required for Review o Many SMS4 Cities and Counties (but not all) review all projects within their jurisdictional area. o Must make a discussion based on the positives and negatives of reviewing all types of projects. o Must make a discussion based on the positives and negatives of reviewing entire jurisdictional area vs. urbanized only. Specific requirements of SMS4 vs DHEC • Does the SMS4 have more stringent design requirements? • 2,10, and 25 year peak flow control • Different permitting processes and review times Regulatory Connection • Areas Required for Review o DHEC webpage has a tool to assist with this. o http://www.scdhec.gov/Environment/WaterQuality/Stormwater/WheretoApply/ Regulatory Connection • Areas Required for Review o Greenville County Location Reviewing Entity Fountain Inn, City of (Including portions of the city located within Laurens County) Greenville County Greenville County Greenville County Greenville, City of City of Greenville Greer, City of City of Greer Mauldin, City of Greenville County Simpsonville, City of Greenville County Travelers Rest, City of Greenville County Address Greenville County Land Development Division 301 University Ridge, Suite 3900 Greenville, SC 29601 Website Greenville County Land Development Division 301 University Ridge, Suite 3900 Greenville, SC 29601 Website City of Greenville Engineering and Public Works Dept.

The manner that it was utilized during the last permit cycle and the way it is used in the regulation were inconsistent. QLP Things You See In The Field Basic SMS4 Permit Requirements • Section 4.2.4 of SCR030000 -Construction Site Storm Water Runoff Control o Develop, implement, and enforce a program to reduce pollutants in any stormwater runoff to the SMS4 from construction activities that result in a land disturbance ≥ 1 acre. Basic SMS4 Permit Requirements • Construction activity includes: o Clearing, grading, and excavating with land disturbance ≥ 1 acre. o Clearing, grading, and excavating that result in disturbance < 1 acre of total land area that is part of a larger common plan of development or sale (LCP). o In coastal counties, any land disturbance within a ½ mile of a receiving water body (but not for single-family homes which are not part of a subdivision development that result in any land disturbance < 5 acres). Basic SMS4 Permit Requirements • Within 18 months from the effective date of coverage, first time permittees shall: o Develop, implement, and enforce a program to reduce pollutants in storm water runoff to their regulated SMS4 from construction activity. o Develop and implement an ordinance or other regulatory mechanism to require erosion and sediment controls, as well as sanctions to ensure compliance, to the extent allowable under State, Tribal, or local law. Basic SMS4 Permit Requirements o Develop requirements for construction site operators to implement appropriate BMPs. o Develop requirements for the design, installation and maintenance of effective pollution prevention measures for construction site operators. o Require each operator of a construction activity to prepare and submit a Stormwater Pollution Prevention Plan (SWP3) prior to the disturbance of land to the SMS4 to review and approve. Basic SMS4 Permit Requirements o Implement procedures for inspecting construction projects. o Develop an Enforcement Response Plan containing a description of how to use specific type of responses to address various types of violations. o Ensure that all staff, whose primary job duties are related to implementing the construction stormwater program, including permitting, plan review, construction site inspections, and enforcement, is trained to conduct these activities. Basic SMS4 Permit Requirements o Develop and implement an effective communication process with construction contractors to educate them on areas in which improvements are needed and to enforce any required actions. o Implement procedures for receipt and consideration of information submitted by the public. Things You See In The Field Typical Construction Program Elements Ordinance and Legal Authority Project Close Out Enforcement Site Inspection Construction Program Plan Review Design Manual Plan Submittal Ordinance and Legal Authority • Considerations o How long it will take to create and pass a new Ordinance to require erosion and sediment controls, as well as sanctions to ensure compliance. Is there political resistance to creating or modifying this Ordinance? Are there special interest groups for or against the SMS4 creating or modifying the Ordinance? Will Ordinance requirements meet minimum standards or will they be more stringent? o Conduct public meeting(s) to educate community. Construction Site Runoff Design Manual • Considerations o Design Requirements Include Requirements of SC Standards for Stormwater Management and Sediment Reduction Regulation 72-300 thru 72-316 72-300. Include Requirements of Construction General Permit SCR100000. o Design Methodologies o Calculations o Standard Specifications o Standard Details • Use Existing Design Manuals o DHEC o Adopt Municipality Manuals o Create Manual specific the SMS4 Plan Submittal Requirements • Submittal Requirements o Notice of Intent (NOI) o Design Plan Requirements Comprehensive SWPPP (C-SWPPP) On Site SWPPP Plan Submittal Checklist Things You See In The Field Plan Review Procedures • Implement site plan review procedures that at a minimum: o Make clear to operators that they are prohibited from commencing construction activity until they receive of written approval of the plans. o Approve SWP3 that complies with: Technical requirements of the effective NPDES General Permit for Storm Water Discharges from Construction Activities, SCR100000, or Establish alternative technical criteria specific to the SMS4 that are equally, or more, protective of water quality. Plan Review Procedures • Implement site plan review procedures that at a minimum: o The SWP3 must include the rationale used for selecting control measures, including how the control measure protects waterway or stormwater conveyance. o Use qualified individuals, knowledgeable in the technical review of SWP3 to conduct reviews. o Document the review of each SWP3 plan using a checklist or similar process. Construction Site Inspection Program • Maintain inventory of all active construction projects. o Inventory continuously updated as new projects are permitted and projects are completed. o Contain relevant contact information for each project (name, address, phone, etc.), size of the project and area of disturbance. o Track the number of inspections for the inventoried construction sites throughout the reporting period to verify the sites are inspected at minimum frequencies required. o Document inspections and enforcement activities for each site in the inventory. Construction Site Inspection Program Site All sites 5 acres or larger in size SMS4 Inspection Frequency All new approvals must be inspected initially within the first 2 weeks of commencement of land disturbing activity. All sites 1 acre or larger that discharge to a tributary listed by the state/tribe as an impaired water for sediment, turbidity, or BIO under the All active sites shall be inspected at least CWA section 303(d) monthly during construction. All sites determined to be a significant threat to water quality* All inactive sites shall be inspected at least bimonthly All other construction sites with 1 acre or more of soil disturbance not meeting the criteria specified above Inspection must occur at least monthly Final Inspection Inspect all permitted projects to ensure that all graded areas have reached final stabilization and that all temporary control measures are removed and permanent stormwater management BMP are permitted as required * In evaluating the threat to water quality, the following factors must be considered: soil erosion potential; site slope; project size and type; sensitivity of receiving waterbodies; proximity to receiving waterbodies; non stormwater discharges; past record of noncompliance by the operators of the construction site; proximity to sensitive water bodies; and, other factors relevant to particular SMS4. Enforcement • Develop an Enforcement Response Plan (ERP) o Description of how to use specific type of responses to address various types of violations. o Types of response; Verbal warnings, Written notices, and Escalated enforcement measures such as citations, notice of violation (NOV), fines, stop work orders, etc. DHEC Involvement Things You See In The Field Enforcement • Develop an Enforcement Response Plan (ERP) o Specific strategies for escalating enforcement response, where necessary, to address persistent, repeat or escalating violations. o Ensure ERP is reasonably effective in reducing pollutant discharges to the MEP and to protect water quality. Project Close Out • Project Close Out Procedures • Close Out Inspection • Notice of Termination (NOT) Staff Training • Ensure all staff, whose primary job duties are related to implementing the construction stormwater program, including permitting, plan review, construction site inspections, and enforcement, is trained to conduct these activities. • Training can be conducted by permittee or outside training. Certified Erosion Prevention and Sediment Control Inspector (CEPSCI) Certified Stormwater Plan Reviewer (CSPR) South Carolina Association of Stormwater Managers (SCASM) Clemson University Center for Watershed Excellence Carolina Clear Master Pond Manager Post-Construction BMP Inspection Landscape Professional o IECA Training Events o o o o Decisions • How many potential projects do you anticipate to permit annually? • Do you have current staff to implement the program? • Do you need to hire more staff? • Do you need to train staff? • Do you need to make capital purchases to implement the program? • How will you fund the program? • Is this a responsibility you can take on? o Consider intergovernmetnal agreements with other MS4s to implement this program?
