I've noted that Japanese knotweed was found in segments A & B of R-2518 (Not sure about R-2519 A, yet). It
seems that procedures should be developed to apply anytime it's encountered in an area to be disturbed by
construction or mitigation activities to ensure it isn't spread by clearing & grading and that it doesn't compromise
the mitigation site. We should start with this project, but astate-wide policy should follow.

David,
EPA sent our comments via letterhead last week, but I do have another issue to bring up before the end of
the comment period.
During our field meetings in 2006, we found Japanese knotweed at Mitigation Site I (Middle Fork Creek),
one of the restoration sites. The mitigation plan doesn't mention it, nor does it describe how invasive
species will be controlled at mitigation sites.
We recommend that Japanese knotweed be controlled on mitigation sites by cutting in the spring, and
then direct application of glyphosate (Round up or Rodeo) to the plant in the fall. Any cuttings should be
removed from the site and bagged to keep the cuttings from resprouting. It may take several years of
cutting and application to eradicate the knotweed, but we would expect DOT to control the species during
the 5-year monitoring period.
DOT should incorporate these recommendations in the mitigation plan and pay close attention to them,
since a significant presence of Japanese knotweed may affect the vegetative success of the site.
Thanks for the continued opportunity to comment,
Kathy Matthews
