Thanks to Caroline Barnett, Cordova Branch Library Manager, for passing these two sites along:
NPMS — “The National Pipeline Mapping System (NPMS) is a geographic information system (GIS) created by the U.S. Department of Transportation, Pipeline and Hazardous Materials Safety Administration (PHMSA), Office of Pipeline Safety (OPS) in cooperation with other federal and state governmental agencies and the pipeline industry. The NPMS consists of geospatial data, attribute data, public contact information, and metadata pertaining to the interstate and intrastate gas and hazardous liquid transmission pipelines, liquefied natural gas (LNG) plants, and hazardous liquid breakout tanks jurisdictional to PHMSA.”–From the website.
811 — “A new, federally-mandated national “Call Before You Dig” number, 811 was created to help protect you from unintentionally hitting underground utility lines while working on digging projects. People digging often make risky assumptions about whether or not they should get their utility lines marked due to concerns about project delays, costs and previous calls about other projects. These assumptions can be life-threatening.”– From the web site. 811 is the number you should call before beginning any digging project.
