The water and sediment environmental impact statements included in the model output each correspond to one of five determinations regarding consultation with NOAA Fisheries. These “effect” determinations will be helpful in screening the potential impacts of the proposed project and assessing whether the project can proceed with informal or formal consultation with NOAA Fisheries.
An “effect” determination on treated wood applications should be based on both general preservative chemical information and project site-specific conditions. The driving factors in determining the potential effects of treated wood on aquatic resources are:
The assessment process in its current draft can be used for the following types of projects that may utilize treated wood projects in the aquatic environment:
Note that projects involving construction in and over water may have potential impacts to NOAA trust resources unrelated to treated wood. Assessment of these related impacts are not addressed by this model and other guidance should be referenced to assess those potential effects.
