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.
