White Wolf Lodge Boiler Replacement (2017 YH)
Yosemite National Park » White Wolf Lodge Boiler Replacement (2017 YH) » Document List
JUSTIFICATION:
The propane boilers were installed with a temporary propane tank which needs to be replaced with a long-term solution. A structurally sound, safe, and efficiently source of heat is critical to the daily activity of guests and employees in White Wolf. The conversion of diesel boilers is a requirement of the Concession contract, and is meant to reduce the need for diesel air quality certifications and reduce overall air pollution in the Park.
SCOPE:
This project will supply the hot water tanks at the White Wolf shower house/restroom building with a 1000 gallon propane gas storage tank.
This process began in 2016 when the diesel boiler was removed and replaced by two new commercial grade 100 gallon propane hot water tanks will be installed to supply the hot water required for the domestic use of the shower restroom. The site has been examined by J S West Propane and they have recommended a code compliant placement of one 1000 gallon propane storage tank alongside the existing propane tank and install underground piping in new trenching to the bathhouse. The installation of the feeder line will involve digging a four inch by 24-inch trench approximately 30-feet in length.
Plumbing the two hot water tanks in series will ensure an adequate supply to the single building. One 1000 gallon certified storage tank will be added to the site per the attached drawing and plumbed to the building via an in-ground trench. The recommended placement site of the storage tank will enable access to fill the tanks and also provide the required minimum clearance from possible ignition sources. In addition, the propane storage additions will enable the diesel generator to be replaced with a 100kW propane powered gen set, also required by terms of the new concession contract, also expected to occur during spring set up.
Although no fencing is required for this size of tank per NFPA 58:6.21.4, fencing is proposed to screen the non-historic propane tanks within the historic district.
This work is proposed to occur during the opening of the complex in spring 2020.
Photo-documentation will be performed before, during and after construction by the contractor and project manager.
