What is the NPMS? l A GIS created by OPS in cooperation with government and industry l Natural gas transmission and hazardous liquid pipelines; LNG facilities l Geospatial data, attribute data, and metadata l A voluntary initiative

The NPMS Model l Repositories : National Repository in Alexandria, Virginia : 14 state repositories: ê Alabama, California, Connecticut, Illinois, Kansas, Kentucky, Louisiana, Maine, Minnesota, New Jersey, Oklahoma, Texas, Virginia, Washington ê New repositories are solicited through the Commerce Business Daily (CBD)

NPMS Repositories WA NJ LA AL VA KY IL TX OK KS CA MN ME National Repository CT TX

NPMS Repositories (cont.) l State repositories collect data for pipelines within their state boundaries. l The National Repository collects data for states without repositories and incorporates state repository data into a seamless national dataset.

The NPMS Model (cont.) l Standards : Operator Standards ê describe how operators can participate in the NPMS : Repository Standards ê describe the operations of the National Repository and the state repositories l Both sets of standards may be downloaded from the NPMS website.

Status of the NPMS As of July 1, 2001, the NPMS contains: l 86% of hazardous liquid pipelines l 42% of natural gas transmission pipelines l 56% of all pipelines being collected

The Role of the NPMS at OPS

Integrity Management Program IMP - Rulemaking Pipeline Integrity Management in High Consequence Areas [Hazardous Liquid Operators with 500 or More Miles] : Objective: To improve pipeline safety through new requirements for testing, integrated evaluation of risk information, improved federal/state oversight of integrity management plans, and enhanced communication to communities.

High Consequence Areas l Key Feature: IMP provides protection for OPS-defined High Consequence Areas (HCA’s). l HCA’s are geographic areas where the consequences of a pipeline release would be most adverse.

High Consequence Areas (cont.) HCA’s are defined as: l Environmentally Unusually Sensitive Areas (USA’s) : Drinking Water and Ecological l Populated Areas : High Population Areas and Other Populated Areas l Commercially Navigable Waterways

HCA Data l Unusually Sensitive Areas : Drinking Water -- current states -- CA, IL, KS, LA, MO, MT, NM, OK, TX, and WY ê Current states contain approximately 70-75% of hazardous liquid pipeline mileage ê Goal to complete Drinking Water USAs by February 2002 ê Available for download from the NPMS Web site

HCA Data (con’t) l Unusually Sensitive Areas : Ecological -- current states -- CA, CO, DE, IA, IL, IN, KS, KY, LA, MI, MN, MO, MS, MT, ND, NE, NM, OH, OK, SD, TX, VT, and WY ê Current states contain approximately 85-90% of hazardous liquid pipeline mileage ê Goal to complete Drinking Water USAs by February 2002 ê Operator must request the data through OPS

HCA Data (con’t) l Populated Areas : High Population Areas (HPAs) ê 1990 US Census defined Urbanized Areas ê 2000 US Census Urbanized Areas available in 3rd quarter 2001 ê HPAs updated by January 2002 (if Census completes Urbanized Areas by anticipated date) ê Available for download from the NPMS Web site

HCA Data (con’t) l Populated Areas : Other Populated Areas (OPAs) ê 1990 US Census defined Census Designated Places (CDPs) ê 2000 US Census CDPs available in 3rd quarter 2001 (if Census completes CDPs by anticipated date) ê OPAs updated by January 2002 ê Available for download from the NPMS Web site

HCA Data (con’t) l Commercially Navigable Waterways (CNWs) ê National Waterway Network created by various agencies including US Coast Guard and US Army Corps of Engineers ê Identifies only waterways that support large commercial traffic ê Available for download from the NPMS Web site

Additional Data Layers (non-IMP) Additional data currently available: l Earthquake, hurricane, flood, and landslide hazard indexes l State/County boundaries l U.S. DOT BTS National Transportation Atlas Data
