The NPMS Public Map Viewer allows everyone, including the general public to view maps of Gas Ttransmission, Hazardous Liquid and Carbon dioxide pipelines, Liquefied Natural Gas (LNG) plants, and Hazardous Liquid breakout tanks in one selected county. Gas Distribution and Gas Gathering systems are not included in NPMS. Users are permitted to print maps of the data, but the data is not downloadable. Always call 811 before digging. Visit https://call811.com/Before-You-Dig for more information.

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 hazardous liquid trunklines and hazardous liquid low-stress lines as well as gas transmission pipelines, liquefied natural gas (LNG) plants, and hazardous liquid breakout tanks jurisdictional to PHMSA.

The National Pipeline Mapping System (NPMS) includes a geographic information system (GIS) dataset containing the location and selected attributes of gas transmission and hazardous liquid pipelines, liquefied natural gas (LNG) plants and breakout tanks (BOT) under jurisdiction of the Pipeline and Hazardous Materials Safety Administration (PHMSA). Effective October 1, 2015, pipeline and LNG plant data is collected annually from pipeline operators as required by 49 CFR §§ 191.29 and 195.61. This metadata is for the national pipeline dataset. There is NPMS pipeline data for all 50 states as well as the District of Columbia and Puerto Rico. The NPMS pipeline dataset contains gas transmission and hazardous liquid pipelines subject to regulations from PHMSA. The NPMS pipeline dataset does not contain gas gathering, gas distribution, or hazardous liquid lines not subject to 49 CFR § 195.61 and can never be used in place of contacting a one call center prior to digging. Distribution of NPMS data in GIS format is handled for PHMSA by the National Repository and is limited to pipeline operators and local, state, tribal, and federal government officials and is subject to data access limitations and agreements. Fulfillments of data requests will include data only for the area of jurisdiction of the person requesting the data (data requests are fulfilled per county/counties, state, or the entire U.S.). Instructions for requesting NPMS data in a GIS format are outlined on the NPMS website at www.npms.phmsa.dot.gov.

The National Pipeline Mapping System (NPMS) Public Viewer enables the user to view NPMS pipeline, liquefied natural gas (LNG) plant and breakout tank data one county or offshore area at a time, including attributes and pipeline operator contact information. The user can also view gas transmission and hazardous liquid pipeline accidents and incidents going back to 2002 for the entire US. NPMS pipeline data consists of gas transmission pipelines and hazardous liquid pipelines jurisdictional to PHMSA. It does not contain gas gathering or distribution pipelines, such as lines which deliver gas to a customer 's home. Therefore, not all pipelines in an area will be visible in the Public Viewer. As well, the breakout tank data is not complete as submission of that data is not a requirement. All NPMS data is for reference purposes only. It should never be used as a substitute for contacting a one-call center prior to excavation activities. Please call 811 before any digging occurs.

To view the data, select a state or the federal waters category and then a county or offshore area from the drop-down lists below. To view another county or offshore area, click the Change County link at the top right corner of the map window. Please note that the Public Viewer limits the scale of pipeline maps, in accordance with PHMSA's security policy. When you are zoomed in closer than a 1:24,000 scale (above zoom level 14), you will notice that the pipelines have disappeared from the map. In order to see the pipelines, you must either zoom out to zoom level 14 or lower. Data cannot be downloaded from the Public Viewer. The boundary between counties and offshore state waters is for display purposes only and is not an official boundary.

The Pipeline and Hazardous Materials Safety Administration (PHMSA) Pipeline Safety Regions dataset was compiled on October 04, 2022 from the Pipeline and Hazardous Materials Safety Administration (PHMSA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). PHMSA’s Office of Pipeline Safety (OPS) is responsible for protecting people and the environment from pipeline failures by analyzing pipeline safety and accident data; evaluating which safety standards need improvement and where new rulemakings are needed; setting and enforcing regulations and standards for the design, construction, operation, maintenance or abandonment of pipelines by pipeline companies; educating operators, states and communities on how to keep pipelines safe; facilitating research and development into better pipeline technologies; training state and federal pipeline inspectors; and administering grants to states and localities for pipeline inspections, damage prevention and emergency response. The PHMSA Pipeline Safety Regions layer contains polygon features representing each of the five regions, Central, Eastern, Southern, Southwest, and Western, that make up PHMSA’s Office of Pipeline Safety. Each region office is charged with ensuring the safe, reliable, and environmentally sound operation of the nation's pipeline infrastructure. Despite regional divisions the jurisdiction of PHMSA staff is nationwide and not limited to their regional area of responsibility.

Line features representing approximate pipeline locations in Chatham County, NC and surrounding counties. The main purpose of this dataset is to provide a visual display of said pipeline locations for critical infrastructure and emergency response planning. The NPMS is a geographic information system (GIS) dataset containing the location and selected attributes of the major gas transmission and hazardous liquid transmission pipelines, and liquefied natural gas (LNG) plants operating in United States and other offshore entities. Effective October 1, 2015 pipeline and LNG plant data is contributed annually by pipeline operators as required by the Pipeline Safety: Miscellaneous Changes to Pipeline Safety Regulations (http://www.regulations.gov/#!documentDetail;D=PHMSA-2010-0026-0054). This metadata is for the entire national dataset.Distribution of NPMS data is handled for PHMSA by the National Repository and is limited to pipeline operators and local, state, and federal government officials. Neither the United States Government nor any party involved in the creation and compilation of NPMS data and maps guarantees the accuracy or completeness of the products. NPMS data has a target accuracy of +/- 500 feet and resides in geographic coordinates. NPMS data must never be used as a substitute for contacting the appropriate local one-call center prior to digging.Chatham GIS SOP: "MAPSERV-76"

The US Map of Suspected Well Water Impacts includes incidents in which oil and gas related events are suspected in events that have an impact upon ground water in the United States. There are multiple layers to the map, each with its own source, and therefore credibility.Visitor Submitted Impacts: This layer consists of viewer submitted form data describing suspected incidents of groundwater contamination by oil and gas extraction and related industries. The locations have been determined using the centroids or geometric center-points of the zip code in which the suspected incident occurred. If you are aware of additional incidents, please submit them here.Pipeline Incidents Contaminating Groundwater: This data layer includes hazardous liquid pipeline incidents that were indicated as resulting in groundwater contamination between 1/1/2010 and 3/29/2013. The data were obtained by the US Department of Transportation Pipeline and Hazardous Materials Safety Administration (PHMSA). The data have been altered by the FracTracker Alliance in that it only includes incidents leading to groundwater contamination, and by the removal of several dozen columns of data about the incident.NRDC Suspected Contamination Events: Amy Mall of the Natural Resources Defense Council compiled a list of 37 incidents where hydraulic fracturing is suspected of contributing to groundwater contamination. The list was compiled in December 2011, and each entry is linked to news reports of the event. This layer was mapped by the FracTracker Alliance based on the centroids or geographic center-points of the municipality, county, or state of the incident, depending on the best information available.List of the Harmed Suspected Water Incidents: Jenny Lisak, co-director of the Pennsylvania Alliance for Clean Water and Air, maintains a list of people claiming to be harmed by hydraulic fracturing or related processes, called the List of the Harmed. This data layer is based on the February 23, 2013 update of the list, and contains only the events in which water is the suspected exposure pathway. This data was mapped by the FracTracker Alliance based on the centroids or geographic center-points of the municipality, county, or state of the incident, depending on the best information available. NM Pit Contamination Events: This layer consists of events where the New Mexico Oil Conservation Division determined that substances from oil and gas pits contaminated groundwater. Altogether, there are 369 incidents included in the data. The document on which this map was based was published in 2008.Complaints to PADEP: Laura Legere, a reporter with the Scranton Times-Tribune, submitted a Right-to-Know law request to PADEP for documents related to people complaining of their well water being impacted by oil and gas drilling, hydraulic fracturing, and related activities. Inclusion on this map layer just means that there was a complaint to PADEP, and should not be construed as proof of a causal relationship between the gas well activity and supposed ground water impact. However, 161 of the incidents have documentation where PADEP establishes a connection between drilling activity and well water impacts. Please note that locations are not exact. They were created by finding the centroid, or geographic center-point, of each municipality. Names of those claiming well water impacts are not included in the data for this map.

This program was created by Congress in 1968 to help provide a means for property owners holding federally backed mortgages to financially protect themselves in the event of a flood. Flood insurance is mandatory if you live in a high-risk area and have a mortgage from a federally regulated or insured lender.Source: https://www.fema.gov/media-library/assets/documents/12886Updated July 2019North Dakota Flood Plains - 500 YearThe "500-year flood" corresponds to an AEP of 0.2-percent, which means a flood of that size or greater has a 0.2-percent chance (or 1 in 500 chance) of occurring in a given year.Source: https://www.fema.gov/media-library/assets/documents/12886Updated July 2019North Dakota Flood Plain - FloodwayA "Regulatory Floodway" means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height. Communities must regulate development in these floodways to ensure that there are no increases in upstream flood elevations. For streams and other watercourses where FEMA has provided Base Flood Elevations (BFEs), but no floodway has been designated, the community must review floodplain development on a case-by-case basis to ensure that increases in water surface elevations do not occur, or identify the need to adopt a floodway if adequate information is available.Source: https://www.fema.gov/media-library/assets/documents/12886Updated July 2019
