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 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.

In accordance with 19.15.27 and 19.15.28 NMAC, each natural gas gathering system at which venting or flaring occurred, the operator shall separately report the volume of vented natural gas and the volume of flared natural gas for each month in each category listed below. Beginning April 2022, the operator shall submit a form C-115B monthly on or before the 15th day of the second month following the month in which it vented or flared natural gas.The categories are:(a) emergency;(b) non-scheduled maintenance or malfunction, including the abnormal operation of equipment;(c) routine repair and maintenance, including blowdown and depressurization;(d) beneficial use, including pilot and purge gas, fired equipment and engines;(e) gathering pipeline blowdown and purging;(f) gathering pipeline pigging;(g) storage tanks;(h) venting as a result of normal operation of pneumatic controllers and pumps;(i) improperly closed or maintained thief hatches; and(j) other surface waste as defined in Subparagraph (b) of Paragraph (1) of Subsection W of 19.15.2.7 NMAC that is not described above.
