By following the proper steps in and around your construction sites, you can help protect our most precious natural resource, our Colorado water.
The Keep it Clean Partners have adopted ordinances that control all construction/development activity that disturbs one or more acres of land, as well as activity that disturbs less than 1 acre of land, but is part of a larger common plan of development.
The owner and/or operator of the construction site will be responsible for complying with these requirements and plays a key role in protecting our water quality. These requirements include temporary erosion and sediment control practices during construction and the installation of permanent stormwater quality facilities to ensure long-term protection of the water quality for runoff from the developed site.
Fines up to $1,000 per day for ordinance violations
Fines may be imposed if the following guidelines are not met.
In general, construction and development contractors are responsible for:
- During Design Review— Owner/operator must develop the following:
- Stormwater Management Plan (SWMP), including erosion and sediment control practices and proposed permanent stormwater quality controls or Best Management Practices (BMPs). Guidelines for preparing a SWMP can be found at CDPHE’s website . Temporary and permanent stormwater quality controls, or BMPs, are to be designed according to the Urban Drainage and Flood Control District’s Urban Storm Drainage Criteria Manual –Volume 3, or other methods approved by the community.
- Owner/operator is responsible for the following: executing a maintenance agreement with the municipality to ensure future inspection, maintenance, repairs, and proper functioning of the permanent BMPs.
- During Pre-Construction Meeting— Owner/operator must provide:
- A copy of the application submittal for coverage under the State’s General Permit of Construction Activities.
- Documentation of an erosion and sediment control administrator for personnel responsible for supervising the installation and maintenance of sediment and erosion control practices.
- During Construction— Owner/operator is responsible for the following:
- Maintain a copy of the SWMP onsite at all times. The approved SWMP must be maintained and made available upon request.
- Install and maintain erosion and sediment control BMPs as specified in the SWMP. Sediment, debris or other pollutants from construction operations must be managed to prevent flow to the storm drainage system.
- Maintain inspection and maintenance records of BMPs onsite with the SWMP.
- The installation and maintenance of BMPs shall be supervised by personnel certified in erosion and sediment control.
- After Construction— Owner/operator is responsible for the following:
- Implement ongoing inspection, maintenance, and repairs of permanent BMPs according to the maintenance agreement with the municipality.
- Submit written documentation that permanent BMPs were constructed in accordance with approved plans submitted in the design review phase.
- General Requirements for all Construction Activities (regardless of size) –
Owner/operator is responsible for the following:
- Manage construction activities to prevent the illegal discharge of sediments or other pollutants to the storm drainage system.
- Receive a permit from CDPHE to discharge any non-stormwater discharge to the storm drainage system. These discharges may include those covered under the State’s CDPS permit system, such as construction dewatering.
