  2. Themes for Change • Comprehensive requirements • Complimentary E&S/PCSM requirements • Reference water quality protection and permitting regulations • Post-Construction Stormwater Management

  3. Earth Disturbance Activities(other than agriculture) • Maintain a minimum vegetated buffer or riparian forest buffer width of 100 feet in special protection waters and a minimum of 50 feet width in waters other than special protection between disturbed areas and top of bank of a watercourse, or natural or artificial lake, pond, or reservoir • Develop criteria for management activities within buffer areas

  4. Planning and Implementation • ID special protection BMPs to protect and maintain the water from degradation in • special protection watersheds; or • where a TMDL has been developed for siltation • Post Construction Stormwater Management (PCSM) • Manage post construction stormwater volume, rate, and water quality • ID PCSM Plans and Narrative Requirements • Maintain a minimum riparian forest buffer from top of bank along a watercourse, or natural or artificial pond, lake or reservoir

  5. General • Reference design manuals for BMP design, installation and maintenance • Temporary stabilization standard and permanent stabilization standard • ID Property rights and off-site discharges • ID monitoring and inspection requirements • Include Preparedness, Prevention and Contingency (PPC) Planrequirements

  6. Permit Activities • 1-5 Acres with a point source discharge • 5 acres or more • 25 acres timber harvesting or road maintenance activities • 5 acres or more for oil and gas related earth disturbance activities • Operation and maintenance of PCSM BMPs

  7. IPs for Higher Risk Activities • Proposed project areas with extensive earth disturbance (e.g. 50 acres or greater) • Proposed project areas with high % impervious • Proposed PCSM volume or rate increases • Earth disturbance in sensitive areas such as headwater areas, steep slopes, geologic formations of concern, flood prone areas and wetlands

  8. Permit Applications • ID permit application requirements • Plans prepared and sealed by a qualified licensed professional • Revised permit fees • ID public notice and public hearing requirements and responsibilities • ID public access to information • ID permit approval, denial, and duration
