Recent studies have determined that suitable coal resources for underground coal gasification exist in a number of geographical regions of the US. States with high potential for UCG include Illinois, Texas, Washington and Wyoming. Each state has established its own administration and procedures to obtain operating permits for an industrial facility such as an UCG site. This paper presents the permitting procedures, and information and mitigation requirements for issuance of air quality, water quality, and mining and natural resources permits for an UCG facility. Unique characteristics of the permitting process in some states will also be presented.
