MS4 – Stormwater

The MS4 Issues Stormwater Work Group was formed in 2012 to create an open forum to discuss stormwater-related permit issues. The first item for discussion was the roadway reconstruction memorandum prepared by CDPHE and issued on January 20, 2012. The memo stayed any enforcement issues on the roadway reconstruction issue until further dialogue could be had with the MS4 Issues Work Group.

When available, the current year and previous year meeting summaries, presentations, and handouts are kept on this page. For documents older than two years, please visit the button for Archives or use the search function.

The MS4 Workgroup meets quarterly. Each meeting will be spent examining one MS4 permit topic of interest and exploring:
• Intent of the topic as it relates to permit requirements
• The current requirements
• Potential issues/challenges/impacts
• Opportunities for improvements
• Identifying any further action can support a better permit

The intent of this format is for WQCD staff and stakeholders to collaborate on a common understanding of the issues and share knowledge in a way that results in future permits that maximize existing MS4 resources while meeting the intent of the permit requirement. Topics have included construction SWMP review requirements and post construction O&M inspection requirements.
