      • Minimize Size and Duration of Disturbance
      • Stabilization
      • Buffer Zones
    • KYR10 Permit Requirements
      • SWPP Plans
      • Permittee develop & implement prior to commencement of construction activities
      • Include erosion prevention measures, sediment control measures & site management practices to prevent discharge of pollutants and minimize impacts
      • Measures and practices selected shall be based on site specific conditions
      • Installed and maintain to effectively minimize discharges from storm events up to and including a 2-year, 24-hour event
    • KYR10 Permit Requirements
      • SWPP Plans cont’d
      • Site Description
      • Site Map(s)
      • Description of other industrial activities
      • Documentation of Stormwater Controls
      • Maintenance of Stormwater Controls
      • Non-Stormwater Discharge Management
      • Inspections – Permittee Conducted
      • Maintaining an Update Plan
      • Signature, Plan Review & Making Plans Available
    • KYR10 Permit Requirements
      • SWPP Plan – Site Map Requirements
      • Property Boundary (lots)
      • Anticipated Post Grading Drainage Patterns (slopes)
      • Areas of disturbance, fill and borrow areas
      • Locations of sediment control measures, erosion control measures, and other site management practices
      • Locations of surface waters, karst features, discharge points
      • Locations of equipment & material storage, wash out areas, waste management areas, and egress
    • KYR10 Permit Requirements
      • SWPP Plans – Maintenance of Controls
      • Controls are to maintained in an effective operating condition
      • USEPA recommends sediment control devices be maintained at no more 1/3 capacity
      • Maintenance shall be conducted if practicable before the next storm event for controls or management practices that are failing or require maintenance
    • KYR10 Permit Requirements
      • SWPP Plan – Permittee Inspections
      • Regular inspections
      • – Once every 7 days
      • – Once every 14 days and within 24 hours of any storm event of 0.5 inches or greater
      • Inspectors
      • – Knowledgeable & skilled in assessing site conditions &
      • effectiveness of measures & management practices
      • – Training in stormwater construction management KEPSC, CEPSC, CPSWQ, TNEPSC, CESSWI Or other similar training
      • – Prepare & retain reports on all inspections
    • KYR10 Permit Requirement
      • SWPP Plan- Signature, Plan Review & Making Plans Available
      • Signed & certified in accordance with 401 KAR 5:065, Section 1(11)
      • Current copy shall be readily available from date of project initiation to date of Notice of termination.
      • Make available upon request to federal, state and local agencies involved in regulating stormwater discharges
    • KYR10 Permit Requirements
      • Minimum Size & Duration of Disturbance
      • At all times minimize disturbance and period of time the disturbed area is exposed without stabilization practices.
      • • Critical areas
      • – Within 25 feet of & on a positive slope toward a water of the Commonwealth
      • – Erosion prevention measures implemented on disturbed areas within 24 hours or as soon as practical after completion of disturbance/grading or following cessation of activities
    • KYR10 Permit Requirements
      • Stabilization Requirements
      • Final Stabilization
      • – Permanently ceased initiate within 14 days of date of cessation
      • – Suspended for 180 days or more initiate as soon as practical but no later than 14 days after the 180th day of suspended activity
      • Temporary Stabilization
      • Within 14 days of the date of temporary cessation
    • KYR10 Requirements
      • Buffer Zone Requirements
      • Buffer Zone required between edge of water body and any disturbance
      • High Quality & Impaired (Non-construction related) maintain a 25 foot buffer zone
      • Impaired (Sediment, no TMDL) maintain a 50 foot buffer zone
      • If cannot be maintained adequately protective alternative practices may be employed
      • SWPPP shall explain any alternate practice & how it is adequately protective
