APPENDIX D

Carbon Sequestration Practices

National Air Quality Initiative (NAQI) Approved Practice Matrix

Note: The following practices have either specific air quality-related purposes or have a direct positive impact on air quality and are approved for use in NAQI states. Other supporting practices may be necessary and require approval prior to being offered as part of NAQI implementation. Supporting practices may be requested by NAQI states with justification. The actual predicted benefits of the practices listed below are determined by the resource setting and practice design for the selected practice.

Practices are shown for their typical ability to address each respective air contaminant that contributes to an air resource concern. 'High' means the practice typically provides moderate to substantial improvement in the respective air resource. Similarly, 'Medium" refers to slight to moderate improvement, and 'Low" refers to neutral to slight improvement.
