Summary
Abstract: This GIS data layer represents the Northeast Gateway Lateral, a project that proposes to construct and operate a new approximately 16-mile long, 24-inch diameter natural gas pipeline lateral that will interconnect with Algonquin's existing offshore I-10 (Hubline) natural gas pipeline system in Massachusetts Bay. The original survey for the bottom position of the pipeline was established by a combination of surface position of the installation vessel using DGPS, diver's surveys, multibeam surveys, and sidescan surveys. The project was surveyed in accordance with the USACOE's minimum standards and techniques as defined in the engineering manual EM 1110-2-1003. This file represents Project layout as of 09/27/05.

Purpose: The data was developed in support of Algonquin's Application to the U.S. Maritime Administration and the U.S. Coast Guard for the Construction of the Northeast Gateway Deepwater Port. June 2005, and the Supplemental Environmental Report for the Northeast Gateway Deepwater Port and Pipeline Lateral. October 2005. The data is subject to change as a result possible issues remaining in the local, state and federal regulatory permit approval process, and minor changes typical between permit plans and as-built conditions. Component of Massachusetts Office of Coastal Zone Management Human Uses database.

Quality
ATTRIBUTE ACCURACY REPORT: These is no assignment of attributes to these data.

LOGICAL CONSISTENCY REPORT: A georeferenced line CAD file was submitted as source data. Subsequent testing of the data was not performed.

COMPLETENESS REPORT: The line feature was mapped as a result of a georeferenced engineering CAD file. This line file was used to derive the completeness of the pipeline route.

HORIZONTAL POSITIONAL ACCURACY REPORT: An accuracy report was not conducted on the data although the location of the converted and projected shapefile file was checked for consistency by overlaying it on the original electronic CAD file.

VERTICAL POSITIONAL ACCURACY REPORT: n/a
