Stormwater regulations can be complex, but compliance is critical to protect water quality and avoid costly fines. Our goal at Summit is to help you find the best path to compliance. To make things simpler, we’ve outlined below the top ten ways you can ensure compliance. Feel free to use it as a checklist for your project!
1. Identify Applicable Regulations
The first step is to identify which stormwater regulations apply to your project—federal, state, and/or local—and confirm the responsible jurisdictions. In Colorado, most construction projects require both a state permit through the CDPS program and local stormwater permits, so understanding the requirements early ensures you stay compliant and avoid costly delays.
2. Obtain the Required Permits
For any project over an acre of disturbance, or part of a larger plan of development, it is required to obtain the Colorado Discharge Permit System (CDPS COR400000) permit. Depending on the location and activities planned during your project, you may also be required to obtain a local MS4 permit. It is important to keep all permit documentation on-site and up to date.
3. Develop a Stormwater Management Plan (SWMP)
Create a site-specific plan that identifies potential sources of pollution. This is typically contracted out to an environmental/stormwater consultant company or civil engineer. The SWMP includes details on Best Management Practices (BMPs) and inspection schedules. It is important to keep your SWMP up to date and have it reflect the site’s conditions and activities changes.
4. Implement Best Management Practices (BMPs)
Install appropriate erosion and sediment controls that are detailed in the SWMP, such as silt fences, wattles, or inlet protections. Implement non-structural BMPs like good housekeeping and employee training. Maintain BMPs regularly for full effectiveness.
5. Conduct Regular Inspections
According to the CDPS permit, stormwater inspections must be completed at least every 14 days and after a significant rainfall event. Some local jurisdictions, such as the City and County of Denver, require a minimum of every 7 days. Contracting a good stormwater consultant can help make sure these inspections are conducted regularly and the reports are kept organized. Make sure to address and correct any deficiencies immediately.
6. Maintain Records and Documentation
Keep inspection reports, training logs, maintenance records, and communication logs organized. These documents can be kept either physically or digitally for at least three years (or per permit requirements).
7. Train Staff and Subcontractors
Ensure all employees understand stormwater requirements and BMP maintenance. WIth everyone keeping an eye out, deficiencies can be prevented or corrected quickly. It’s often helpful to provide refresher training when new equipment, materials, or processes are introduced.
8. Manage Waste and Materials Properly
This can be considered a BMP (good housekeeping), however it’s very important to store chemicals, fuels, and waste in covered, contained areas. Dispose of construction and industrial waste according to local regulations. Prevent spills and have cleanup kits readily available. If not stayed on top of, these seemingly little things can add up to a big violation.
9. Communicate with Regulatory Agencies
Maintaining good communication is key for smooth processes and unannounced state or city inspections. Notify CDPHE or your local MS4 agency of any discharges or permit changes. A proactive approach will not only help your project stay compliant, but avoid any misunderstandings.
10. Review and Update Annually
Thoroughly reviewing your SWMP periodically will help address any concerns and better reflect your project conditions. Update your BMPs and procedures to reflect site changes, new regulations, or lessons learned.
