The Massachusetts Department of Environmental Protection (MassDEP) Major Facilities datalayer is a statewide point dataset containing the location of a subset of facility types regulated by MassDEP’s Bureau of Air and Waste (formerly the Bureau of Waste Prevention (BWP)).
The following “major” facility types have been located:
- Facilities with Air Operating Permits (AIR)
- Hazardous Waste Recyclers (HWR)
- Hazardous Waste Treatment, Storage and/or Disposal Facilities (TSDF)
- Large Quantity Generators of MA-regulated Hazardous Waste (LQG_MA)
- Large Quantity Generators of EPA/RCRA-regulated Hazardous Waste (LQG_RCRA)
- Large Quantity Toxic Users (LQTU)
New in 2016: Facilities with Ground Water (GWD) and Surfacewater (SWD) discharge permits have been removed from this layer. Permitting of these activities is currently managed by the MassDEP Bureau of Water Resources (BWR). See the MassDEP Ground Water Permits layer for Ground Water discharge locations.
The layer is stored in ArcSDE as BWPMAJOR_PT.
In April 1998, MassDEP’s Facility Master File Database (FMF) was queried to identify facilities engaging in the activities listed above. A “development coverage” was created from this data using global positioning system (GPS), address-matched, and coordinate-derived data developed at MassDEP and EPA Region 1. The data are current as of April 29, 2016.
The primary sources of information for this datalayer include:
- Site-specific knowledge of BAW Compliance and Enforcement staff
- GPS field verification by MassDEP staff
- Surveys, site plans and locus maps from MassDEP records
- Interpolation of orthophoto imagery and parcel data from MassGIS
The Attributes section of this page contains additional information regarding data sources utilized in the development of this datalayer.
Point Development Tool
To facilitate conversion of institutional knowledge and paper data to a digital format, the MassDEP GIS Program created the Point Development Tool (PDT), a customized application using ESRI’s ArcView software (the PDT application is available as an extension to the MassGIS DataViewer). The PDT provides a standardized platform that guides users through the automation and documentation of geographically referenced point data. MassDEP technical staff used the PDT to locate facilities based on knowledge gained in the course of their professional activities. On screen digitizing using the PDT was the primary method of automation.
Using data in the “development coverage,” the PDT navigates data developers to the general vicinity of a site. The PDT then displays the best digital base imagery available for that vicinity. In 1998, the PDT used MassGIS 1 meter (1:5,000) black and white digital orthophoto images (DOQ) as the default basemap. Where 1 meter 1:5,000 DOQs were not available, the PDT defaulted to 1 meter USGS (1:12,000) black and white digital orthophoto images or (1:25,000) USGS topographic quadrangle imagery respectively. When data development began, the only available digital basemap imagery for much of Massachusetts was the MassGIS scanned USGS (1:25,000) topographic images. Therefore, the base scale of this datalayer is considered to be 1:25,000.
In the absence of staff with professional knowledge, facility files were checked for location information. Facility files maintained by MassDEP contain a variety of types and quality of maps, including surveys, site plans and locus maps. MassDEP GIS and BAW Program staff reviewed this file information and identified the best manuscript maps and supplemental text information for locating sites. When suitable maps were not available, field verification was performed by MassDEP staff. Locations were entered using the PDT. With multiple years of orthophoto imagery and the increased availability of parcel data, many recently mapped locations were developed without the need for fieldwork.
The point attribute table for the MassDEP Major Facilities datalayer contains the following fields:
General Facility Information Fields:
FIELD TYPE-WIDTH DEFINITION FAC_ID Long Integer Facility ID from Facility Master File (FMF) Database. The FAC_ID is a unique identifier used in the FMF Database to identify facilities and their ownership. FAC_NAME Text - 45 Facility Name from the FMF Database ADDRESS Text - 38 Number and street address of the facility, as listed in the FMF Database. TOWN Text - 21 The standard MassGIS city/town name. REGION Short Integer A code corresponding to the MassDEP Region in which the facility is located. This field uses standard MassDEP Region codes:
REGION DEP REGION – Office location ACRONYM 1 Western Region - Springfield WERO 2 Central Region - Worcester CERO 3 Northeast Region - Wilmington NERO 4 Southeast Region – Lakeville SERO RTN Text - 9 DEP BWSC 21e Release Tracking Number (RTN). If a relationship between a BWP Facility and a BWSC Chapter 21e site was uncovered in the data development process, the RTN field will be populated. The RTN is a unique 7-digit site identifier assigned to reportable releases by the BWSC. This number is preceded by the digit 1, 2, 3, or 4 (e.g. 3-0001234) according to the MassDEP region in which the site is located (see: description of REGION above). HW_ID Text - 12 EPA Hazardous Waste Generator ID from the RCRAINFO database. A unique identifier generated by RCRAINFO, EPA’s database formerly known as the Resource Conservation and Recovery Information System (RCRIS). SW_ID Text - 10 Historic Solid Waste Facility ID from MassDEP’s Solid Waste Facility database. SSEIS_ID Long Integer Stationary Source Emission Inventory System ID from MassDEP’s AirQual database. This unique identifier is a composite ID composed of an EPA Air Quality Control Region identifier (AQCR) and a Plant ID. NPDES_ID Text - 15 National Pollution Discharge Elimination System ID, a unique identifier generated by the EPA. If a relationship between a BWP Facility and a NPDES facility was discovered in the data development process, the NPDES_ID field will be populated.
Major Activity Fields:
The Major Activity Fields are Y/N fields indicating which of the more significant types of activities occur at a given facility. There are no specific if/then relationships between any of the Major Activity fields. Although Ground and Surface Water discharges are no longer regulated within the Bureau of Air and Waste, the GWD and SWD fields remain (null) for structural consistency.
FIELD TYPE-WIDTH DEFINITION AIR Text - 1 Air Operating Permit: A value of “Y” indicates the facility has an active air operating permit. This is a permit with specific restrictions on the type and amount of particulate or other matter emitted from the facility. GWD Text - 1 Groundwater Discharge Permit: Historic field has Null value. HWR Text - 1 Hazardous Waste Recycler: A value of “Y” indicates the facility engages in the recycling of hazardous waste.
