The Erosion and Sediment Control Manual is one tool for complying with the federal Clean Water Act. The Manual describes requirements for developers and construction managers to keep dirt, mud, rocks and sediment on-site when building occurs.
Erosion control is important for maintaining water quality and nutrients in soil. It is also important for protecting nearby streams and the fish and wildlife that inhabit them.
The Erosion and Sediment Control Manual provides guidelines for developing erosion control plans. It also offers best practices for managing run-off of sediment and other materials when construction or other ground-disturbing activities occur.
The final draft of the Erosion and Sediment Control Manual is now available for public review and comment. It is available to download from the link below. The draft manual focuses on:
- Clarifying when and where the manual applies
- Clarifying permanent stabilization requirements for the end of the construction period
- Clarifying which erosion, sediment, and pollution control measures (Best Management Practices) are required when and where; some apply in all situations, some apply only in special circumstances such as steeply sloping sites or sites in close proximity to water bodies.
- Emphasis of continued maintenance of erosion control measures during construction
- Technical updates
Public comment on the proposed final draft of the Erosion and Sediment Control Manual will be accepted through Friday, Sept. 16.
