| Abstract | Note: This record was created on 2/11/04 and updated 1/31/07 at the Minnesota Land Management Information Center (651-201-2499 or clearing.house@state.mn.us ) using information from the NPMS metadata record online at: https://www.npms.phmsa.dot.gov/ Check this online location for any updates to the U.S. DOT metadata. ------------------------------------------------------------------------------------------------- The U.S. Department of Transportation (U.S. DOT), Pipeline and Hazardous Materials Safety Administration (PHMSA) is working with other federal and state agencies and the pipeline industry to create a National Pipeline Mapping System (NPMS). The NPMS is a full-featured geographic information system (GIS) containing the location and selected attributes of the major gas transmission and hazardous liquid transmission pipelines, and liquefied natural gas (LNG) facilities operating in United States and other offshore entities. Michael Baker Jr., Inc. (Baker), as the primary contractor assumes all responsibilities of the NPMS National Repository regarding NPMS database updates, synchronization, and maintenance. Source data is contributed annually by pipeline operators to the National Repository. This metadata is for the entire national dataset. Additional metadata for individual pipeline systems are also available. 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 plus or minus 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. |

Recent events have focused additional security concerns on critical infrastructure systems. Due to these concerns, PHMSA no longer provides unlimited access to pipeline data. PHMSA is committed to providing pipeline related data to pipeline operators complying with integrity management programs and to community officials. Pipeline operators and local, state, and Federal government officials wishing to download the pipeline data should send requests to opsgis@dot.gov Include your: Name Title Organization Mailing Address Phone Number Fax Number Email Address PHMSA Operator ID (Pipeline operators) PHMSA will verify the contact information provided by all requesting individuals.

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

| Associated Data Sets | The data set, 'Gas and Liquid Pipelines, Minnesota Statewide Overview, 1996: Department of Public Safety, Office of Pipeline Safety', previously available from the State of Minnesota, is no longer available. Emergency officials and pipeline operators should instead request the National Pipeline Mapping System described in this metadata record. |

| Section 2 | Data Quality Information | Top of full metadata | Top of page | |
| Attribute Accuracy | The NPMS National Repository checks all entities and their attribute data for compliance with NPMS data standards. These checks do not ensure that NPMS data accurately reflects conditions in the field, only that the attributes meet database design specifications. | |||
| Logical Consistency | The National Repository is responsible for ensuring 1) that all geospatial data are complete and correctly projected to the proper geodetic datum, 2) that the attribute data are compliant with the NPMS data standards. However, NPMS is built from contributions of data from pipeline operators. Operator contributions vary in many respects. Logical consistency of NPMS data cannot be guaranteed. | |||
| Completeness | The NPMS represents hazardous liquid and gas transmission pipelines and LNG facilities under PHMSA jurisdiction. Distribution lines and gathering lines are not represented. The repository verifies each submitted dataset for completeness according to NPMS standards. The repository checks to ensure that all submissions include the required geospatial data, attribute data, and metadata. PHMSA makes every effort to ensure that the NPMS is complete and that pipeline and LNG facility operators comply with the NPMS Congressional mandate. | |||
| Horizontal Positional Accuracy | Positional accuracy of plus or minus 500 feet has been attempted for all pipelines and LNG facilities. Actual positional accuracy depends on the spatial accuracy of the pipeline operators' submission. Thus, actual positional accuracy of NPMS data varies. Positional accuracy is indicated in the QUALITY_CD field found in both the pipeline and LNG facility attribute tables. Positional accuracy is designated as E, V, G, P, or U where E = Excellent: within 50 feet, V = Very Good: 50-300 feet, G = Good: 301-500 feet, P = Poor: 501-1000 feet, and U = Unknown. | |||
| Vertical Positional Accuracy | N/A | |||
| Lineage | Source materials: Various pipeline operators. All pipeline and LNG facility datasets submitted to NPMS by pipeline operators for processing are required to originate from scale sources less than or equal to 1:24000. Metadata for individual pipeline systems indicate Source Scale. Processing steps: The NPMS data compilation process begins when a pipeline or LNG facility operator submits data to the National Repository. In total there are seven major steps in the NPMS process: 1. Operator Submission. The process starts when an operator sends information (termed submission) to the NPMS repository. 2. Repository Check-in. The repository logs the submission, scans digital submissions for viruses, inventories the submission, notifies operator of submission receipt, and initiates tracking procedures. 3. Metadata Review and Repair. The repository will review the metadata file that is supposed to accompany each NPMS submission. If problems exist with the metadata, the National Repository will work with the operator to complete the submission. 4. Data Conversion. Submissions with hard-copy geospatial data are separated from submissions with digital geospatial data. Hard-copy submissions are digitized, and digital submissions are translated. Attribute data is matched to the appropriate line features and reviewed for compliance with the standards. At the end of this step, the data will be in ARC/INFO format and ready for final processing. 5. Quality Assurance and Quality Control. Harvard Design and Mapping Inc. (HDM) performs an independent quality control review and reports findings back to the National Repository. HDM does not make repairs to the data. The repository must make repairs and resend the data to HDM. The process continues until HDM approves the submission. 6. Check Plot Review by Operators . The repository prepares a random selection of check plots for review by the submitting operator. Operators are asked to review and comment on the check plots. 7. Data Incorporation. The repository incorporates the data into the master database. |

| Distribution Liability | 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, Office of Pipeline Safety as part of the National Pipeline Mapping System (NPMS). The data is compiled from contributions made by the pipeline and LNG facility operators and is processed by private contractors. 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 product. 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. | |||
