LAYER NAME/LOCATION	LAYER BRIEF DESCRIPTION
100 Year Floodplains - Regulated Facilities/Streams & Water/Flooding	Floodplains are categorized according to their estimated statistical frequency of flooding. Land designated a 100-year floodplain has a one percent chance of being flooded in any given year. In reality, floods in these areas can occur year after year, or they can fail to occur in a century. The National Flood Insurance Program offered by the Federal Emergency Management Agency (FEMA) uses this 100-year floodplain standard to determine the need for flood insurance.
500 Year Floodplains - Regulated Facilities/Streams & Water/Flooding	Floodplains are categorized according to their estimated statistical frequency of flooding. Land designated a 500-year floodplain has a 0.2 percent annual chance of flooding. In other words, there is a possibility of one flood every 500 years. Like the 100-year floodplain, floods can occur in consecutive years, or not at all in a 500-year period.
7.5 Minute Quad Boundaries - Boundaries	The 7.5 minute quadrangle boundaries mirror the USGS (United States Geological Survey) quadrangles.
Abandoned/Orphaned Wells - Regulated Facilities/Oil and Gas	This layer depicts the locations of abandoned and orphaned wells known by the Pennsylvania Department of Environmental Protection. This information is acquired when orphaned and abandoned wells are discovered by Pennsylvania municipalities, landowners and other agencies and then reported to the Pennsylvania Department of Environmental Protection. When abandoned and orphaned wells are investigated, a scoring is assessed to the well. High priority wells with no responsible party are addressed by the Well Plugging Program. Those wells are analyzed and occasionally lower priority wells are included if located in close proximity to the high priority wells on well plugging contracts.
Air Emission Plant - Regulated Facilities/Air	Air Emissions Plant is a DEP primary facility type related to the Air Quality Program. The sub-facility types related to the Air Emissions Plant that are included in eMapPA are: Air Pollution Control Device, Combustion Unit, Fuel Material Location, General Administrative Location, Incinerator, Point of Air Emission, and Process.

Approved Trout Waterbodies - Regulated Facilities/Streams & Water/Fish	Many streams, lakes, ponds, and reservoirs are officially classified as "approved trout waters." This means that these waters contain significant portions that are open to public fishing and are stocked with trout. The waters in this layer are lakes (not flowing waters) classified as "approved trout waters" and these are open to trout harvest during the "extended season" (see Commonwealth Inland Waters). Unlisted tributary streams (those not included in this list of "approved trout waters") are not open to harvest of trout during the "extended season." Only approved trout waters and all waters downstream of approved trout waters are open during this period. Spearing fish is not permitted in any of these waters at any time of the year. These waters are closed to all fishing (including taking of minnows) from March 1 to 8 a.m. on the opening day of the trout season. Some of these waters have been included in the Early Season Trout-Stocked Waters Program and are open from March 1 through March 31. A person shall be deemed to be fishing if he or she has in possession any fishing line, rod, or other device that can be used for fishing while on or in any water or on the banks within 25 feet of any water where fishing is prohibited. Check with the nearest Fish & Boat Commission office if there is any question about whether or not a water area is "approved." This layer is current through the new fishing regulations released December of 2010 for the 2011 fishing season.

Bedrock - Areas/POI - Geological	The hard-copy "Geologic Map of Pennsylvania" (Berg and others, 1980) is the most current, available source showing the bedrock geology of the entire state and has had widespread use for regional studies. The Pennsylvania Bureau of Topographic and Geologic Survey (PaGS), responding to numerous requests from federal and state government agencies and the private sector, has converted the geology represented on the 1980 map to a digital format. The purpose is to make the geology of the state available as a "seamless" coverage for use in regional spatial analyses and other digital applications.
Beneficial Land Use - Regulated Facilities/Land Reuse	Beneficial Land Use is a DEP primary facility type related to the Water Pollution Control Program. The sub-facility type related to Beneficial Land Use is the Parcel. A parcel refers to the land application site that is proposed to received biosolids or residential septage.

Census Tracts 2010 - Boundaries	Census tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity, and were defined by local participants as part of the 2010 Census Participant Statistical Areas Program. The Census Bureau delineated the census tracts in situations where no local participant existed or where all the potential participants declined to participate. The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of census data and comparison back to previous decennial censuses. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. When first delineated, census tracts were designed to be homogeneous with respect to population characteristics, economic status, and living conditions. The spatial size of census tracts varies widely depending on the density of settlement. Physical changes in street patterns caused by highway construction, new development, and so forth, may require boundary revisions. In addition, census tracts occasionally are split due to population growth, or combined as a result of substantial population decline. Census tract boundaries generally follow visible and identifiable features. They may follow legal boundaries such as minor civil division (MCD) or incorporated place boundaries in some States and situations to allow for census tract-to-governmental unit relationships where the governmental boundaries tend to remain unchanged between censuses. State and county boundaries always are census tract boundaries in the standard census geographic hierarchy. In a few rare instances, a census tract may consist of noncontiguous areas. These noncontiguous areas may occur where the census tracts are coextensive with all or parts of legal entities that are themselves noncontiguous. For the 2010 Census, the census tract code range of 9400 through 9499 was enforced for census tracts that include a majority American Indian population according to Census 2000 data and/or their area was primarily covered by federally recognized American Indian reservations and/or off-reservation trust lands; the code range 9800 through 9899 was enforced for those census tracts that contained little or no population and represented a relatively large special land use area such as a National Park, military installation, or a business/industrial park; and the code range 9900 through 9998 was enforced for those census tracts that contained only water area, no land area.
Chesapeake Bay Watershed - Areas/POI - Environmental	The Pennsylvania Facility Analysis System (PFAS) uses the Pennsylvania State Water Plan as its reference for displaying the 104 watershed boundaries that are in Pennsylvania. It is from this State Water Plan that the Chesapeake Bay Watershed boundary is derived. This watershed comprises the Susquehanna and Potomac River Basins. The layer has been cut at the north and south borders of Pennsylvania. The only attribute information available is whether or not an area falls within the Chesapeake Bay Watershed. For additional information, visit the link below.
Class A Wild Trout Streams - Regulated Facilities/Streams & Water/Fish	Class A streams are streams that support a population of wild (natural reproduction) trout of sufficient size and abundance to support a long-term and rewarding sport fishery. The Commission does not stock these streams. This GIS layer represents the sections of streams that are designated as such.
Coal Mining Operation - Regulated Facilities/Mining	A Coal Mining Operation is a DEP primary facility type related to the Mining Program. The sub-facility types related to Coal Mining Operations that are included in eMapPA are: Coal-Aboveground Storage Tank - aboveground tanks greater than 250 gallons used to store a regulated substance, motor oil or fuel on a coalmine permit. These tanks are regulated under the coal mining regulations since they are specifically exempted from the storage tank regulations. Discharge Point - Discharge of water from an area as a result of coal mining activities. Mineral Preparation Plant - Facility at which coal is cleaned and processed. Mining Stormwater GP - General permit for Stormwater discharges associated with coal mining activities in which the main pollutant is sediment. Discharge is not into a High Quality or Exceptional Value designated stream. NPDES Discharge Point - An effluent discharge at a coal mine operation permitted under the National Pollutant Discharge Elimination System. Post Mining Treatment - Post-mining discharges are groundwater seeps and flows that occur after a mine has been completed and reclaimed. Many of these discharges have become contaminated by contacting acid producing rock in the mine environment. Untreated discharges that enter clean streams cause acidification, which immediately kills much of the aquatic life. Coal mines that are predicted to have discharges are not permitted; however, coal mining operators are required to treat post-mining discharges in cases where the predictions do not come true. Through advances in predictive science, less than 2 percent of the permits issued today result in a post-mining discharge. New technologies, including alkaline addition and special handling of acid producing material, are being studied in order to help address the remaining 2 percent. Refuse Disposal Facility - An area used for disposal or storage of waste coal, rock, shale, slate, clay, and other coal mining related materials. Refuse Reprocessing - Facility at which coal is extracted from waste coal, rock, shale, slate, clay, and other coal mining related material, i.e., coal refuse.

These investigations are usually initiated by County 911 centers, County EMAs, County Hazmat Chiefs, PEMA, Pa State Police, Local Fire Departments or Local Police Departments and are frequently referred to as Emergency Responses.
Congressional Boundaries - Boundaries	Congressional boundaries determine how the state of Pennsylvania is represented in the United States Congress. These boundaries change once every decade due to population shifts. Reapportionment occurs when Pennsylvania's population, according to the U.S. Census Bureau, dramatically changes with respect to the other states. The House of Representatives can add or remove representatives, depending on the change. With not so significant changes in population, state legislatures can still redistrict. Congressional boundary maps originate in the Department of the State, by the Reapportionment Commission for the Bureau of Commissions, Elections and Legislation.
Conservancies - Areas/POI - Environmental	Part of the Pennsylvania Gap Analysis progression, this dataset was designed to facilitate the interpretation of Pennsylvania's surface vegetation and habitat models for vertebrate species in the Commonwealth.

Designated Use Lakes - Regulated Facilities/Streams & Water/Water Quality	These data, offered to provide a spatial representation of standards contained in the Pennsylvania Code. Title 25 Environmental Protection, Department of Environmental Protection, Chapter 93, Water Quality Standards, are current and accurate to the best of our knowledge and are appropriately updated as required. These data should not be substituted for the official version of the standards in the Pennsylvania code. National Hydrography Dataset NHD layer with a spatial representation of designated water uses defined in Title 25 Environmental Protection, Department of Environmental Protection, Chapter 93, Water Quality Standards. The Pennsylvania Code just cited provides a list of all streams or watersheds (basins) in the state along with their associated designated water uses. This GIS layer displays these uses spatially on an interactive map. Public users can drill down to locations on the map to view and map the designated uses of the water bodies of interest. The layer can also be used in conjunction with other spatially referenced data for spatial analyses. When a lake has both a use and a special protection, the lake is displayed according to the special protection on eMapPA. Do not infer water use from lake color; rather, verify water use under the USE_DESCRIPTION field in the attribute table on an identify.
Designated Use Streams - Regulated Facilities/Streams & Water/Water Quality	These data, offered to provide a spatial representation of standards contained in the Pennsylvania Code. Title 25 Environmental Protection, Department of Environmental Protection, Chapter 93, Water Quality Standards, are current and accurate to the best of our knowledge and are appropriately updated as required. These data should not be substituted for the official version of the standards in the Pennsylvania code. National Hydrography Dataset NHDFlowline layer with a spatial representation of designated water uses defined in Title 25 Environmental Protection, Department of Environmental Protection, Chapter 93, Water Quality Standards. The Pennsylvania Code just cited provides a list of all streams or watersheds (basins) in the state along with their associated designated water uses. This GIS layer displays these uses spatially on an interactive stream map. Public users can drill down to locations on the map to view and map the designated uses of the water bodies of interest. The layer can also be used in conjunction with other spatially referenced data for spatial analyses. When a stream segment has both a use and a special protection, the segment is displayed according to the special protection on eMapPA. For example, a segment that is classified as Cold Water Fish and High Quality Waters (HQ-CWF) will be shown in the High Quality blue-green color. Do not infer water use from stream color; rather, verify water use under the USE_DESCRIPTION field in the attribute table on an identify. When the Streams NHD layer and the Streams Designated Use layer are toggled visible on eMapPA at the same time, they essentially overlap each other. Streams Designated Use has a higher priority in terms of layering, so this layer will be seen on the map. The best practice is to have only one streams layer visible at any given time in order to avoid confusion.
Digitized Mined Area - Regulated Facilities/Mining	Coal mining has occurred in Pennsylvania for over a century. The maps to these coal mines are stored at many various public and private locations (if they still exist at all) throughout the commonwealth. This dataset tries to identify the Mined Out Areas of the various coal seams in Pennsylvania. This information can be used for many environmental related issues, including mine land reclamation and determination of needs for Mine Subsidence Insurance. The information in this dataset was gathered from mine maps at these various locations so that the data can be readily available to environmental professionals.
Encroachment Locations- Regulated Facilities/Water	An Encroachment Location is a DEP primary facility type related to the Water Resources Management Water Obstructions Program.

Code Chapter 93.  The Department maintains a publicly available list of surface waters that have undergone recent existing use evaluations at its website.
Farmline Maps Well Locations - Regulated Facilities/Oil and Gas	In the 150 years since the first oil well was drilled, an unknown number of oil and gas wells have been drilled in Pennsylvania. An estimate by Independent Petroleum Association of America places that number at approximately 325,000. DEP is aware of 2,900 Plugged wells, 8,000 Orphaned and Abandoned Wells and 111,000 permitted wells, which leaves over 200,000 wells unaccounted for. Many Oil and Gas wells are within close proximity to coal mining operations. DEP's Bureau of Mine Safety and Bureau of Oil and Gas PPM are in a joint endeavor to locate abandoned and orphaned wells in active mining areas. This will allow for proper plugging or avoidance prior to mining operations and prevent gas migration. This process included written correspondence to operators requesting Farm Line maps, which were then referenced in GIS to real world locations by using the following control points: roads, houses, water bodies and known coordinates. By using GIS, relative locations were determined and placed side by side with current ariel photography to determine plausible locations of unknown wells. The following attribute fields apply to the nearest plugged well, abandoned or orphaned well, spudded well and permitted well site to the farmline well:Plug_Dist_ft, Plug_Permit, A_O_Dist_ft, A_O_APInum, Spud_dist_ft, Spud_API, Permit_Dist_ft, Permit_API

Coverage showing stewardship of managed conservation lands throughout the Commonwealth. Includes federal, state, county and privately owned lands including National and State Parks, Wildlife Refuges and Forests, county parks, and private conservancy lands
Floodplains - Regulated Facilities/Streams & Water/Flooding	The statewide floodplain layer has been provided in addition to the FEMA 100 and 500-year floodplains in an attempt to fill in the gaps. Currently there are over 20 counties that do not have FEMA floodplain data; however, PASDA has provided general floodplain designations for all counties. When all three floodplain layers are toggled visible in eMapPA, the FEMA 100 and 500-year floodplains will take precedence over this statewide layer. If there is no FEMA data, only the statewide layer will appear. Keep in mind that the statewide floodplain layer does not designate according to the statistical frequency of flooding.
Floodways - Regulated Facilities/Streams & Water/Flooding	A floodway is the portion of the available flow cross section (channel of a stream or any other watercourse and adjacent floodplain area) that cannot be obstructed without causing an increase of more than a foot in water-surface elevations. The Federal Emergency Management Agency has established the amount to be one foot based on floods that occur, on average, every 100 years. Floodways generally depict those areas where flooding is deeper and more severe. The designations are made in an effort to control the increase in flood heights.
Forests - Areas/POI - Environmental	Part of the Pennsylvania Gap Analysis progression, this dataset was designed to facilitate the interpretation of Pennsylvania's surface vegetation and habitat models for vertebrate species in the Commonwealth. Coverage showing stewardship of managed conservation lands throughout the Commonwealth. Includes federal, state, county and privately owned lands including National and State Parks, Wildlife Refuges and Forests, county parks, and private conservancy lands

Groundwater Monitoring Network - Regulated Facilities/Streams & Water/Water Monitoring	Monitoring of groundwater quality in Pennsylvania is usually done near a permitted facility to determine the impacts of the facility on the groundwater, or to monitor as a safeguard for a public water supply well. The Groundwater Monitoring Network layer represents the point locations and data for 1,089 groundwater quality monitoring points sampled under the Fixed Station Network (FSN) and Ambient Survey Groundwater Monitoring Program.
Historical Oil and Gas Well Locations - Regulated Facilities/Oil and Gas	These well locations were derived from historical mine maps known as the WPA, KSheet, and HSheet collections. These locations are provided for informational purposes only and should not be sole means of decision making and are in no way a substitute for actual on the ground observation.
Hydologic Unit Code (HUC) 8 - Regulated Facilities/Streams & Water/NHD/HUC	Hydrologic units are categorized into four levels: regions, sub-regions, accounting units, and cataloging units. Each hydrologic unit is uniquely identified by its code that consists of two-to-eight digits based on the above levels. An eight digit code can be broken down into the following: First two digits identify the region. First four digits identify the sub-region. First six digits identify the accounting unit. Addition of two more digits identify the cataloging unit . According to the United States Geological Survey, a cataloging unit is a geographic area representing part or all of a surface drainage basin, a combination of basins, or a distinct hydrologic feature.

Longwall Mine Panels - Regulated Facilities/Mining	Coal mining has occurred in Pennsylvania for over a century. A method of coal mining known as Longwall Mining has become more prevalent in recent decades. Longwall mining involves cutting the coal off the face of a long wall panel of coal in a single pass of the machinery. The machinery will then advance forward and perform another pass along the coal face. The broken off coal is hauled to the surface using conveyor belts. As the machinery advances forward into the coal panel, the mine roof is allowed to collapse behind it. This dataset identifies the footprint of these longwall panels relative to the surface.

NHD Flowline - Regulated Facilities/Streams & Water/NHD/HUC	This layer represents the streams/rivers in the NHD that intersect Pennsylvania. The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, drinking water supplies, fish habitat areas, wild and scenic rivers. Reach addresses establish the locations of these entities relative to one another within the NHD surface water drainage network, much like addresses on streets. Once linked to the NHD by their reach addresses, the upstream/downstream relationships of these water-related entities--and any associated information about them--can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS). GIS can also be used to combine NHD-based network analysis with other data layers, such as soils, land use and population, to help understand and display their respective effects upon one another. Furthermore, because the NHD provides a nationally consistent framework for addressing and analysis, water-related information linked to reach addresses by one organization (national, state, local) can be shared with other organizations and easily integrated into many different types of applications to the benefit of all.
NHD Waterbodies - Regulated Facilities/Streams & Water/NHD/HUC	The NHD Waterbodies layer is part of the National Hydrography Dataset. It is a base layer that is used to show lakes, ponds, reservoirs, swamps, and marshes.

PA Historic Streams - Regulated Facilities/Streams & Water/Surface Water	This is the Department's legacy master stream coverage. The last updates to this layer occurred in late 2004. This layer has been replaced by the High Resolution National Hydrography Dataset (NHD) and as such should only be used to aid in identifying legacy stream codes. This layer was digitized at a scale of 1/24,000. All streams are connected and have flow direction. Each stream is identified by a unique 5-digit stream code found in the WRDS (Water Resource Data System) field. The streams are further divided into segments. The first stream segment flows from the headwaters to the first tributary. Subsequent segments are tributary to tributary. The final segment flows from the last tributary to the mouth which for purposes of this data layer is defined as the point at which the stream crosses the Pennsylvania boundary. The unique segment identifier is constructed from three concatenated fields. The stream code, downstream river mile, and finally the upstream river mile of the segment boundaries (12345_8.000_ 12.000). The river miles are measured from the mouth, at the Pennsylvania boundary, upstream to the headwaters.
PA MD Instream Flow Study Area - Regulated Facilities/Streams & Water/Surface Water	This shapefile defines the areal extent of the application of the PA-MD Instream Flow Study Model.

PA Water Plan - Regulated Facilities/Streams & Water/Surface Water	This layer is also known as the 104 Watershed Boundaries. The Pennsylvania State Water Plan, originally developed in the 1970s, divided Pennsylvania's major river basins into 20 smaller units, called sub-basins, for planning purposes. Most of these sub-basins are further divided into watershed areas (designated "A", "B", "C" etc.) that range in size from about 100 to 1000 square miles.
PADWIS Intakes- Regulated Facilities/Water	Each point represents surface water intakes serving Pennsylvania public water systems. The data are collected and entered into the Pennsylvania Drinking Water Information System (PADWIS) database by Department staff. Data are downloaded from PADWIS using a SAS script that provides a .dbf of the dataset. The data are then separated into two categories for processing according to the coordinate datum's used for each point. The first category includes those points that have coordinate methods with a WGS 1984 horizontal datum. Those coordinate methods include "D", "5", "O", "F", "E", "A", and "W". The second category for data separation is for those points that have a coordinate method of "S", "T", "U", or those with no information on the coordinate method. It is assumed that these methods are using the North American Datum of 1927. Definitions for these coordinate methods can be found in the Attributes section of the metadata. Different coordinate methods were developed and are entered into PADWIS for each public water system source so that it can be determined if the source location data meets the accuracy standard set by the EPA (< 25 meters) and so it can be utilized for source water assessments through GIS analysis. The goal is for all sources serving PWS to have an accuracy of less than 25 meters by July 31, 2003. Once the data is separated based on the two datum's, the database tables are converted into shapefiles using ArcMap. Each shapefile is projected from its originally assumed datum to a common datum so they can be merged into one shapefile with an Albers Conical Equal Area projection and a WGS 1984 horizontal datum.
PADWIS Wells- Regulated Facilities/Water	Each point represents groundwater sources serving Pennsylvania public water systems. The data are collected and entered into the Pennsylvania Drinking Water Information System (PADWIS) database by Department staff.

PAGIS Well Water Inventory - Regulated Facilities/Streams & Water/Surface Water	DCNR is the source for this data description and the data. This database contains information regarding 165,827 wells, 123,351 of which have latitude and longitude values. This database was created by the Pennsylvania Geological Survey to manage data supplied to them by water well drillers. Data submission began in 1966 using paper forms. Latitude and longitude was determined in the office by interpreting both handwritten directions and a hand-drawn map supplied by the driller. Most of the location and data entry work has been done by temporary employees of the agency, so it is of varying reliability. Typically one county was worked on at a time. No data entry has been done since August of 1994, when York county was updated. Records submitted since the last update are filed by county and township in the Harrisburg offices of the Pa Geological Survey and can be examined by visiting that office. In 1999 the paper files were searched for records that could be located with minimum effort. Interns began assigning coordinates and entering the data for these selected wells. That data will be added to PAGWIS once it has been reviewed. The date of the last update for the Water Well Inventory in each county can be found in field "Last_WWI" of the table "tblCountyCodeLU". Although since 1966 drillers have been obligated by law to submit a completion report for every water well constructed in the state, it is estimated that many thousands go unreported each year.

Urban Areas 2000 - Boundaries	For Census 2000, the Census Bureau classifies all territory, population, and housing units located within an urbanized area (UA) or an urban cluster (UC) as "urban". It delineates UA and UC boundaries to encompass densely settled territory, which consists of: Core census block groups or blocks that have a population density of at least 1,000 people per square mile and Surrounding census blocks that have an overall density of at least 500 people per square mile. In addition, under certain conditions, less densely settled territory might be part of each UA or UC.
Urban Areas 2010 - Boundaries	The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. After each decennial census, the Census Bureau delineates urban areas that represent densely developed territory, encompassing residential, commercial, and other nonresidential urban land uses. In general, this territory consists of areas of high population density and urban land use resulting in a representation of the "urban footprint." There are two types of urban areas: urbanized areas (UAs) that contain 50,000 or more people and urban clusters (UCs) that contain at least 2,500 people, but fewer than 50,000 people (except in the U.S. Virgin Islands and Guam which each contain urban clusters with populations greater than 50,000). Each urban area is identified by a 5-character numeric census code that may contain leading zeroes. Layer has been clipped to a 5 miles radius of Pennsylvania.

Wilderness Trout Streams - Regulated Facilities/Streams & Water/Fish	This layer contains flowing waters from the Pennsylvania Fish and Boat Commission Fisheries Resource Database that are under the Wilderness Trout Designation. Wilderness trout stream management is based upon the provision of a wild trout fishing experience in a remote, natural and unspoiled environment where man's disruptive activities are minimized. Established in 1969, this option was designed to protect and promote native (brook trout) fisheries, the ecological requirements necessary for natural reproduction of trout and wilderness aesthetics. The superior quality of these watersheds is considered an important part of the overall angling experience on wilderness trout streams. Therefore, all stream sections included in this program qualify for the Exceptional Value (EV) special protected water use classification, which represents the highest protection status provided by the Department of Environmental Protection (DEP).
