Area of use: United States (USA) - Maine between approximately 69°40'W and 68°25'W. The area is bounded by the following: Beginning at the point determined by the intersection of the Maine State line and the County Line between Aroostook and Somerset Counties, thence northeasterly along the state line to the intersection of the Fort Kent - Frenchville town line, thence southerly along this town line to the intersection with the New Canada Plantation - T17 R5 WELS town line, thence continuing southerly along town lines to the northeast corner of Penobscot County, thence continuing southerly along the Penobscot County line to the intersection of the Woodville - Mattawamkeag town line (being determined by the Penobscot River), thence along the Penobscot River to the Enfield - Lincoln town line, thence southeasterly along the Enfield - Lincoln town line and the Enfield - Lowell town line to the Passadumkeag - Edinburg town line, thence south-southeasterly along town lines to the intersection of the Hancock County line, thence southerly along the county line to the intersection of the Otis - Mariaville town line, thence southerly along the Otis - Mariaville town line to the Ellsworth city line, thence southerly along the Ellsworth city line to the intersection of the Surry - Trenton town line, thence southerly along the easterly town lines of Surry, Blue Hill, Brooklin, Deer Isle, and Stonington to the Knox County line, thence following the Knox County line to the boundary of the State of Maine as determined by Maritime law, thence following the State boundary westerly to the intersection of the Sagadahoc - Lincoln county line, thence northerly along the easterly boundary of the Maine 2000 West Zone, as defined, to the point of beginning.

Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
