DENVER—The Metro Wastewater Reclamation District Board of Directors has approved a
Suncor Energy USA Inc. proposal for a trench and hanging wall on Robert W. Hite Treatment
Facility (RWHTF) property. 
The RWHTF is adjacent to Suncor’s Commerce City refinery. The trench and wall will help
prevent petroleum pollutants that have leaked underground from Suncor onto Metro’s property
from moving into Sand Creek.
Construction may start as early as this afternoon.
The Board approved the Suncor trench and wall proposal at a special Board meeting this
afternoon. They also approved a Suncor Access and License agreement related to
investigating, mitigating, and remediating contamination at the RWHTF.
The Agreement grants Suncor access to the RWHTF through December 15, 2017. Suncor
needs the access to be able to construct the trench and hanging wall and to meet other
requirements imposed by the Colorado Department of Public Health and Environment.
The Metro District is the largest wastewater treatment agency in the Rocky Mountain West. The
RWHTF at 64th and York treats about 140 million gallons of wastewater a day. The service area
includes nearly 1.7 million people and encompasses approximately 715 square miles, including
Denver, Arvada, Aurora, Brighton, Lakewood, Wheat Ridge, Thornton, and part of Westminster,
together with about 40 sanitation and water and sanitation districts in the metropolitan Denver
