This document outlines the proposed changes to the Colorado onsite wastewater regulations, focusing on new guidelines and frameworks aimed at enhancing water resource protection by 2010. Key updates include a single set of statewide guidelines, streamlined approval processes for advanced treatment systems, and a risk-based code to minimize excessive county requirements. The document also discusses the transfer of title inspections, universal certification for professionals, and necessary adjustments to operational and maintenance requirements. Stakeholder involvement and legislative advocacy are essential for further progress.

Colorado Onsite Regulations…Vision 2010 27 September 2008 CEHA Annual Conference and Exhibition
Hard at Work • May 6th- CPOW Board meeting • June 16th- Regulation revision overview • July 15th- State statute review for revision • August 11th- Guideline review for revision • August 19th- Guideline issues & framework
Current Regulatory Framework • C.R.S. Article 10 – Individual Sewage Disposal Systems Act • Water Quality Control Commission Guidelines for Individual Sewage Disposal Systems • County Regulations
Proposed Regulatory Frameworks • Could duplicate current framework OR • A single set of guidelines could be implemented in all counties
Summary of Proposed Changes to Statute Allow for: • ISDS – OWS • Sewage treatment works = >2000 gpd ? • Technical advisory committee • Risk-based code may eliminate the need for county-level supplementary requirements Supportfor Adoption of Technical Advisory Committee
Summary of Proposed Changes to Statute allow for: • Transfer of title inspection requirements • Universal state-wide certification and licensing of all professionals • Streamlined approval of advanced treatment systems • Restructure permit fee cap (cost recovery only) • Restriction of experimental systems • No platted lot should be deemed un-buildable as a result of onsite wastewater regulation
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)
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)
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
Summary of Proposed Changes to Guidelines • Setback adjustments allowed based upon performance • Certification and CEU requirements for all onsite professionals in the state (CIOWTS Exam on Friday!) • Ensure all systems are accessible for monitoring and maintenance • Tank standards adoption (water-tightness/structural integrity) • List of manufacturers products
Where do we go from here? We’ve come a long way… but we’re not finished yet!
The Next Steps • Complete risk matrices • Design • O&M • Complete legal revision of document • Present documents for local and outside peer review • Gain full support of the WQCC for revised guidelines and statute • Find legislative sponsor(s) & lobby • Propose new legislation in 2010
