WREG has provided support to Tri-State Generation and Transmission for a number of facilities in the western United States. Projects have included:
- An operating permit renewal application for the Rifle Generating Station, a combustion turbine station. WREG also assisted Tri-State in verifying that emission units located at the same site but under the control of another company should not be considered part of the source covered by the operating permit and the emission units should be removed from the operating permit.
- Prepared an operating permit renewal application for the Nucla Generating Station, a coal-fired, atmospheric circulating fluidized-bed combustor producing 100 megawatts of electricity on Colorado’s Western Slope. WREG updated applicable requirements, reviewed operating parameters used to prepare the initial application, prepared Compliance Assurance Monitoring (CAM) plans, and prepared the permit application package.
- Prepared a construction/ operating permit application for modification of a combustion turbine facility to allow for additional annual operating hours.
Since 2007, one of WREG’s Principals has provided ongoing support to Tri-State for multiple projects in a staff augmentation role. Tasks have included emission estimation, regulatory analysis, dispersion modeling, and compliance assistance.
