Acronyms

Acronyms

  • HCA – High Consequence Area

    • CNW – Commercially Navigable Waterway

    • OPA – Other Populated Area

    • HPA – High Population Area

  • NPMS – National Pipeline Mapping System

  • USA – Unusually Sensitive Area – Drinking Water and Ecological


Status of the npms

Status of the NPMS

  • As of June 25, 2002:

    • 90% hazardous liquid mileage

    • 52% natural gas transmission mileage

    • 64% of all mileage

  • Operators can now submit break-out tank data online to the NPMS National Repository

  • 10/31/02 – Discontinue state repository program


Data access

Data Access

  • Post 9/11/01 – Revised data distribution policy

  • 1990 HPA, OPA, and CNW data are available for download from the NPMS website

  • Eco and DW USA data must be requested from OPS via email

  • Pipeline operators can request copies of their submitted NPMS pipeline data

  • Federal, state, and local governments can request copies of the NPMS pipeline data – agree to data redistribution restrictions

  • Public currently has no access to pipeline or USA data


Data access cont

Data Access (cont.)

  • Internet mapping application access was restricted following 9/11/01

  • Secure Internet mapping applications available fall 2002

    • Operators will be able to view their pipeline data in relation to other layers including HCA data

    • Government officials will be able to view data within a geographically defined area

  • Non-graphical public application available (winter 2003)


Data access cont1

Data Access (cont.)

  • Operators can create a “GIS-lite” mapping application using free GIS data viewers and OPS GIS data

  • A list of free data viewers is available from the NPMS website www.npms.rspa.dot.gov


Mapping break out session

Mapping Break-out Session

  • OPS' "GIS-lite" Application Demo

    • Downloading Software from the Internet

    • Data Incorporation

    • Software Limitations

  • General GIS Issues

  • OPS Pipeline Data Collection Efforts

  • HPA and OPA Data Changes based on 1990 vs. 2000 Census

  • CNW Changes and Data Availability

  • OPS Internet Mapping Application Development and Use


New data

New Data

  • 2000 Census population data has been processed (HPA’s and OPA’s)

  • New Commercially Navigable Waterways are nearing completion (fall 2002)

  • USA’s: All states complete except PA Ecological and NY Drinking Water


New data cont

New Data (cont.)

  • New HPA, OPA, and CNW data will be made available at the same time

  • Federal Register notice announcing the availability of the new data (fall 2002)

  • Operators will have one year from the date of the Federal Register notice to incorporate new data into IMP plans


Data changes

Data Changes

  • Commercially Navigable Waterways

    • Minor changes

    • Several lines have been corrected (mostly in Alaska)

    • Several waterways reclassified


Data changes cont

Data Changes (cont.)

  • High Population Areas – 1990 vs. 2000

    • OPS uses Census defined Urbanized Areas for delineation of HPA’s

    • Minor changes

    • Urbanized Area – An area consisting of a central place(s) and adjacent territory with a general population density of at least 1000 people per square mile of land area that together have a minimum residential population of at least 50,000 people.


Data changes cont1

Data Changes (cont.)

  • Other Populated Areas – 1990 vs. 2000

    • OPS uses Census defined Places for delineation of OPA’s

    • Places

      • Incorporated Place

      • Census Designated Place (CDP)

    • 1990 population threshold of 2500 for CDP’s


Data changes cont2

Data Changes (cont.)

  • Other Populated Areas – 1990 vs. 2000 (cont.)

    • No minimum population requirement for CDP’s in 2000

    • Place – A concentration of population either legally bounded as an incorporated place or identified as a CDP.


1990 vs 2000 hpa opa analysis

1990 vs. 2000 HPA/OPA Analysis

  • TIGER 2000 release included 1:100,000 scale Places but not Urbanized Areas

  • 1:5,000,000 scale Urbanized Areas eventually available online

  • Census released in the last few weeks 1:100,000 Urbanized Areas on DVD

  • OPS analysis utilizes 1:100,000 scale Places and Urbanized Areas


Hpa and opa 1990 vs 2000 comparison nationwide statistics

HPA and OPA1990 vs. 2000 ComparisonNationwide Statistics

Note: Pipeline statistics based on approximately 90% of the hazardous liquid pipeline mileage in the NPMS.
