Section 12. For the purpose of more precisely defining said system:

1. The Massachusetts Coordinate System, NAD, 1983, Mainland Zone, Federal Zone Code M2001, is a Lambert conformal conic projection of the North American Datum of 1983, having standard parallels at north latitudes 41° (degrees) 43" (minutes), and 42° (degrees) 41" (minutes), along which parallels the scale shall be exact. The origin of coordinates is at the intersection of meridian 71° (degrees) 30" (minutes), west of Greenwich and the parallel 41° (degrees) 00" (minutes), north latitude. This origin shall have the coordinates: North (Y) = 750,000 meters and East (X) = 200,000 meters.

2. The Massachusetts Coordinate System, NAD 1983, Island Zone, Federal Zone Code I 2002 is a Lambert conformal conic projection of the North American Datum of 1983, having standard parallels at north latitudes 41° (degrees) 17" (minutes) and 41° (degrees) 29" (minutes), along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian, 70° (degrees) 30" (minutes), west of Greenwich and the parallel 41° (degrees) 00" (minutes), north latitude. This origin shall have the coordinates North (Y) = 0 meters and East (X) = 500,000 meters.
