8. Summary of Proposed Changes to Guidelines • New title that reflects our intentions…”Water Resource Protection…” any ideas? • Limit components of regulation that counties may modify • Fees based upon cost recovery with a cap • Address conflicts of interest (designer/regulators…) • Address designer liability (final inspections)

9. Summary of Proposed Changes to Guidelines • Risk classification matrix (EPA Guidelines) - Levels I-V • More representative design flows • Different levels of design ability based upon credential (designer vs. P.E.) • Removal of effluent monitoring requirements for “deemed to comply” systems • Increase flow volumes for site-plan review (>2000 gpd)

10. Summary of Proposed Changes to Guidelines • Permits issued for 1-5 years with inspection to verify conditions (county flexibility) • Permits shall be transferred at time of sale • Implementation of transfer of title inspection requirement (Currently-Jefferson, Boulder, Summit, Pitkin Counties) • O&M and inspection requirements determined by risk matrix
