AC The acronym for Alternating Current. It i s an electric current in which the flow of electric charge periodically reverses direction, whereas in direct current (DC, also dc), the flow of electric charge is only in one direction. AFP The acronym for Alternative Financing and Procurement. An AFP model brings together private and public sector expertise in a unique structure that transfers the risk of project cost increases and scheduling delays typically associated with traditional project delivery. Area of Potential An area within the Study Area where one or more contaminants are potentially Environmental Concern present, as determined through the Contamination Overview Study including (APEC) identification of past or present land uses of concern and/or identification of a Potentially Contaminating Activity (PCA). AREMA The acronym for American Railway Engineering and Maintenance-of-Way Association. AREMA is the organization that represents the engineering function of the North American railroads. Autotransformer Apparatus which helps boost the overhead contact system (OCS) voltage and reduce the running rail return current in the 2 X 25 kV autotransformer feed configuration. It is a single winding transformer having three
