It would not fall under the nutrients provisions; it does not promote the growth of vegetation or algae.

If you were looking at the kind of capital that Mr. Wasilenkoff said is required to adapt an existing facility — and, if you are entering the industry today and you saw value-added products from carbohydrates and small cellulosic polymers even for jet engine fuel to specialty chemicals — how do you see the forestry by-product area competing with products emerging in terms of the rapidly growing biomass: that is, the fast growing small bushes to grasses and what we are beginning to see in terms of the use of algae and some bacteria as mass producers of cellulose-like or small carbohydrate polymers.

If this caused an increase in nutrients to this nutrient poor river, it could stimulate the growth of algae and a shift in the diversity and abundance of aquatic insects, with pollution tolerant species displacing more common species, such as mayflies.
