The Commonwealth held a robust and comprehensive public review of the Draft Phase III WIP from April 5 through June 7, 2019, as evidenced by the more than 4,800 comments received. Multiple, significant revisions to the Draft Phase III WIP were necessary to improve clarity, to provide updated information, and to offer additional explanation and detail for specific initiatives. The efforts by many organizations and individual citizens that went into the development of the Phase III WIP and the input during the public comment period are greatly appreciated.

The next six years will continue to require engagement from all nutrient source sectors, whether regulated or unregulated, whether governed by permits or voluntary, whether encompassing large facilities or individual citizens. Virginia will assess its progress every two years as part of periodic milestone updates and all interested stakeholders are encouraged to stay engaged and continue their contributions to a successful restoration effort.
