Surface Water Protection Branch

Background

Forestry activities can disrupt ecosystems and contribute significantly to nonpoint source (NPS) pollution through the creation of roads, removal of vegetation, prescribed burns, and destabilization of streambanks. These activities can create a feedback loop of soil degradation if BMPs are not properly installed or maintained.

Regulatory Requirements

Hawaii Administrative Rules (HAR) Chapter 11-56 identifies certain forestry operators and landowners in 11-56-3 as applicable to nonpoint source pollution regulations.

If your operation is considered applicable, you will be required to complete the three steps below. Even if 11-56-3 does not include your operation, all forestry landowners and operators are encouraged to voluntarily complete these actions to protect water quality.

• Register with the Surface Water Protection Branch
• Develop a Water Pollution Prevention Plan (WPPP)
• Implement Best Management Practices (BMPs)

Best Management Practices

BMPs include a variety of actions to prevent nonpoint source pollution. HAR Chapter 11-56, Appendix B lists BMPs for forestry activities such as:

• Reducing the risk of landslides & erosion by identifying high erosion-hazard areas and limiting activities in those areas
• Planting native vegetation and vetiver in Stream Management Zones (SMZs)
• Developing and using roads only when absolutely necessary
• Maintaining stream crossings to prevent overflow onto roads and excess erosion
