On August 3, 2015 the Environmental Protection Agency (EPA) released the Clean Power Plan Final Rule (CPP), which includes national standards for greenhouse gas emissions from existing power plants. Following the announcement, Platte River participated in a stakeholder process initiated by the State of Colorado in preparation for development of a State Plan intended to meet the requirements of the CPP. Participation included attending various public meetings and engaging with state officials to ensure that Platte River interests are considered in policy decisions. Platte River also engaged with EPA in the federal rulemaking process by providing comment on additional aspects of the CPP that have not yet been finalized. Staff submitted separate comments but also worked closely with the Large Public Power Council (LPPC) to develop comments submitted on our behalf. Platte River was involved with the federal rulemaking process leading up to the August announcement and was familiar with the proposed version of the CPP. The final version is significantly different and more complicated than the proposed version, which has required significant additional analysis to assess potential impacts. However, the U.S. Supreme Court stayed the plan on February 9, 2016, due to pending legal challenges. At this time, Platte River is preparing to comply with all Clean Power Plan regulations if the stay is lifted and the plan is implemented.
