Zan,

Based upon our most recent phone conversation, you were agreeable to our revisions for the slope repair with the
exception of the use of SC250 vegetated liner. We are proposing to change the use of SC250 and will now proposed to
used Rolanka BioD-Mat 90 (see attachment to this email). This matting has a comparable shear stress rating without the
potential to harm wildlife. I hope this change will result in approval of our permit request.

Sincerely,

Thomas Kelley, PE
