NPMS PIPELINES AND NPMS BREAKOUT TANKS IN L.A. COUNTY

NPMS_PIPELINES_LACOUNTY        NPMS_PIPELINES_BREAKOUT_TANKS_LACOUNTY

These data sets are for the purpose of tracking all gas transmission pipelines, hazardous liquid transmission pipelines, and LNG plants in the United States as well as some breakout tanks. The data will be used to support the assessment risk associated with the Nation’s liquid and gas pipeline infrastructure.

Note: This dataset contains pipelines in Los Angeles County only. The data has been re-projected from Geographic to NAD_1983_StatePlane_California_V_FIPS_0405_Feet. Other than re-projecting, the data is provided as received from U.S. DOT.

Description

The NPMS is a geographic information system (GIS) dataset containing the location and selected attributes of the major gas transmission and hazardous liquid transmission pipelines, and liquefied natural gas (LNG) plants operating in United States and other offshore entities. Effective October 1, 2015 pipeline and LNG plant data is contributed annually by pipeline operators as required by the Pipeline Safety: Miscellaneous Changes to Pipeline Safety Regulations (http://www.regulations.gov/#!documentDetail;D=PHMSA-2010-0026-0054). Pipeline operators may opt to voluntarily submit location and attribute data for breakout tanks under their operation. This metadata is for the entire national dataset.

Distribution of NPMS data is handled for PHMSA by the National Repository and is limited to pipeline operators and local, state, and federal government officials. Neither the United States Government nor any party involved in the creation and compilation of NPMS data and maps guarantees the accuracy or completeness of the products. NPMS data has a target accuracy of +/- 500 feet and resides in geographic coordinates. NPMS data must never be used as a substitute for contacting the appropriate local one-call center prior to digging.

Use limitations

Due to security issues, pipeline data can only be released to pipeline operators and certified local, state, and federal government officials. Use at own risk. NPMS maps and/or computer data have been compiled by the United States Department of Transportation, Pipeline and Hazardous Materials Safety Administration as part of the National Pipeline Mapping System (NPMS). The data is compiled from contributions made by the pipeline operators and is processed by private contractors.

Access Constraints: The NPMS pipeline data is available to pipeline operators and federal, state, and local government officials. Pipeline operators will only be provided data they contributed.

Use Constraints: Neither the United States Government nor any party involved in the creation and compilation of NPMS data and maps guarantees the accuracy or completeness of the products. NPMS data should be considered no more accurate than ±500 feet and must never be used as a substitute for contacting the appropriate local one-call center prior to digging.

Note: This data may be provided to only governmental entities within Los Angeles County. All other governmental entities must request the data from the U.S. Dept. of Transportation.

Because of this dataset’s reliance on information or materials from outside sources, the County makes no warranty, representation, or guarantee as to the content, sequence, accuracy, reliability, timeliness, or completeness of this dataset.

    Hi Site Admin,

    I would like to download this dataset but I can’t figure out how to do it. Can you give me a tip?

    Thanks,
