Milwaukee Regional Medical Center Thermal Services, Inc. (MRMC Thermal) is developing the organizational structure and operating assets to provide steam and chilled water service to the MRMC campus including the acquisition of the Milwaukee County Power Plant (MCPP) that was owned and operated by We Energies (WE). NV5 supported MRMC Thermal throughout the multiple stages of transitioning and upgrading the plant to their service, ensuring that each stage met all federal and local permitting and modeling requirements.
The transition involved several phases, including the use of temporary boilers, removal of boilers from service, boiler modification, addition of new permanent boilers in two separate buildings, cooling towers – new and replacement, emergency generation and fuel oil storage. NV5 performed dispersion modeling to demonstrate that ambient air quality standards (NAAQS) are protected through each phase of the project. The Wisconsin Department of Natural Resources (DNR) required dispersion modeling be submitted for the 1-hour NO2 standard. In addition, Wisconsin DNR did not accept EPA’s Tier 2 or Tier 3 methods for modeling NO2, so NV5 was challenged with finding a solution to demonstrate modeled compliance with the NO2 standard. Because the 1-hour NO2 standard is difficult to meet with 6 operational boilers combusting fuel oil, NV5 completed dispersion modeling to demonstrate that any combination of 4 boilers combusting fuel oil could meet the 1-hour NO2 standard.
With the establishment of MRMC Thermal Services, all the MRMC campus members became part of a “single facility” that must be included in the MRMC Thermal Title V permit. NV5 was also retained to complete the Title V Permit application and assist the member organizations with maintaining compliance with the new requirements. In addition to providing air permitting services, NV5 also provided Owner’s Technical Representative and acted as the commissioning agent for the transitional boiler plant.
