Patton State Hospital: Steam Boiler, Piping and Steam Traps
Document Type
NOE - Notice of Exemption

Document Description
The Department of Mental Health proposes an energy conservation project to replace one of three existing steam boilers at Patton State Hospital. The new boiler would have dual fuel burner capabilities, natural gas and Amber 365 backup fuel. Asbestos abatement work related to steam boiler replacement will be conducted. New underground steam piping would be installed in both the eastside and westside loop system with tie-ins to buildings at existing locations, with the exception of the Auditorium. At the rear of the Auditorium, new piping would be mounted on the exterior of the building with entrance to the building through an existing louver. Trenching to depths of five-feet on average would be required for pipline installation. The new steam pipeline distribution system would contain improved thermal insulation and energy conservation properties. The routing for the pipeline system is being designed to avoid tree loss and detrimental impacts to mature trees at the facility. Existing underground steam lines are to be abandoned in place and would not be removed. The project also involves replacement of steam traps.
