Deny a federal wetland permit to Tonquin Holdings for a quarry which will damage or destroy wetlands on and adjacent to the Tualatin River National Wildlife Refuge.


The Tualatin River National Wildlife Refuge is an Aquatic Resource of National Importance established in 1992 by an act of Congress. The permit would allow the applicant to excavate a 250' deep quarry on wetlands contiguous with the refuge and on wetlands contiguous with a private conservation easement. This quarry would interrupt the natural hydrology of the wetlands on the refuge and cause irreparable damage.

This area of the refuge contains unique kolk ponds formed by massive floods at the end of the last ice age 14,000 years ago.Rare reptiles (western pond turtles) and amphibians (northern red-legged frogs) live in the kolk ponds.This unit of the refuge is also notable for the absence of invasive plant species.

Located on the outskirts of Portland, Tualatin River National Wildlife Refuge is one of only a handful of urban national wildlife refuges in the country. Situated within the floodplain of the Tualatin River, the Refuge comprises less than 1% of the 712 square mile watershed. Yet, due to its richness and diversity of habitats, the Refuge supports some of the most abundant and varied wildlife in the watershed.

The Refuge is now home to nearly 200 species of birds, over 50 species of mammals, 25 species of reptiles and amphibians, and a wide variety of insects, fish and plants.

Signing this petition encourages the Army Corps of Engineers to enact provisions of the federal Clean Water Act to protect the refuge and its welands from irreparable damage.
