Office of Pipeline Safety 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
3
Office of Pipeline Safety 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
4
Office of Pipeline Safety 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
5
Office of Pipeline Safety 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)
6
Office of Pipeline Safety 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
7
Office of Pipeline Safety 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
8
Office of Pipeline Safety 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
9
Office of Pipeline Safety 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
10
Office of Pipeline Safety Data Changes Commercially Navigable Waterways °Minor changes °Several lines have been corrected (mostly in Alaska) °Several waterways reclassified
11
Office of Pipeline Safety 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.
12
Office of Pipeline Safety 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
13
Office of Pipeline Safety 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.
14
Office of Pipeline Safety 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
15
