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 • 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 • 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.) • 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 (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 • 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 • 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 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 • Commercially Navigable Waterways • Minor changes • Several lines have been corrected (mostly in Alaska) • Several waterways reclassified
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 (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 (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 • 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
