Equipment and Sustainability
Sevenson’s investment in new construction equipment meets the highest energy savings and low carbon emission standards established by the USEPA
Supporting our commitment to sustainable remediation, 75% of Sevenson’s fleet is comprised of equipment that meet USEPA’s Tier 3 emission and fuel standards, upgrading both replacement and additional new fleet equipment with Tier 4 interim, and Tier 4 final engines. All company equipment burns ultra-low sulfur diesel fuel. On all projects where equipment is used on water, biodegradable oil is used in the hydraulic systems of the machines. Sevenson has continued to upgrade its fleet by replacing retired equipment with units that meet the most current emission standards established by the USEPA.
