Overview

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 Waste Prevention (BWP). The layer is stored in ArcSDE as BWPMAJOR_PT.

The following “major” facility types have been located:

  • Large Quantity Generators of Hazardous Waste (LQG)
    • Large Quantity Generator of MA-regulated Hazardous Waste (LQG_MA)
    • Large Quantity Generator of EPA/RCRA-regulated Hazardous Waste (LQG_RCRA)
  • Large Quantity Toxic Users (LQTU)
  • Hazardous Waste Recyclers (HWR)
  • Hazardous Waste Treatment, Storage and/or Disposal Facilities (TSDF)
  • Facilities with Air Operating Permits (AIR)
  • Facilities with Groundwater Discharge Permits (GWD)
  • Facilities with Surface Water Discharge Permits (SWD)

Data Universe
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 January 2013.

Data Sources
The primary sources of information for this datalayer include:

  • Site-specific knowledge of BWP 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 attribute section of this document contains additional information regarding data sources utilized in the development of this datalayer.

Production

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 3.x software (the PDT application was 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.

Basemap Scale
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.

Other Methodologies
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 BWP 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.

2. Description of General Facility Information Items
General facility information attributes are populated using MassDEP‘s Facility Master File (FMF) Database.

a. FAC_ID
Facility ID from MassDEP‘s Facility Master File (FMF) Database. The FAC_ID is a unique identifier used in the FMF Database to identify facilities and their ownership.

b. FAC_NAME
Facility name from the FMF Database.

c. ADDRESS
Number and street address of the facility, as listed in the FMF Database.

d. TOWN
The standard MassGIS town name.

e. REGION
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 

f. 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 Release Tracking Number (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).

g. HW_ID
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).

h. SW_ID
Historic Solid Waste Facility ID from MassDEP’s Solid Waste Facility database.

i. SSEIS_ID
Stationary Source Emission Inventory System ID from MassDEP’s AirQual database.  This unique identifier is a composite ID comprised of an EPA Air Quality Control Region identifier (AQCR) and a Plant ID.

j. NPDES_ID
If a relationship between a BWP Facility and a National Pollution Discharge Elimination System (NPDES) facility was discovered in the data development process, the NPDES_ID field will be populated.  The National Pollution Discharge Elimination System ID is a unique identifier generated by EPA.

3. Description of 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.

a. AIR
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.

b. GWD
A value of “Y” indicates the facility has an active Type I or Type II groundwater discharge permit.  Type II permits require more extensive review than Type I permits and corresponding discharges are considered more significant than Type I discharges.  Please note we have attempted to locate the center of the facility rather than a specific discharge location.  Refer to the L_TYPE to see which facility feature was mapped.

c. HWR
A value of “Y” indicates the facility engages in the recycling of hazardous waste.

d. LQG_MA
A value of “Y” indicates the facility is a large quantity generator of one or more Massachusetts regulated hazardous wastes, including but not limited to, waste oil and PCBs.

e. LQG_RCRA
A value of “Y” indicates the facility is a large quantity generator of one or more EPA-RCRA regulated hazardous wastes.

f. LQTU
A value of “Y” indicates the facility is permitted as a large quantity toxics user and falls under the requirements of the Toxic Use Reduction Act (TURA).  For a Toxics Use Reduction Act overview, visit the DEP TURA webpage.

g. TSDF
A value of “Y” indicates the facility engages in the treatment, storage and/or disposal of hazardous wastes.

h. SWD
A value of “Y” indicates the facility has an active Type I or Type II surface water discharge permit.  Type II permits require more extensive review than Type I permits and corresponding discharges are considered more significant than Type I discharges.  Please note we have attempted to locate the center of the facility rather than a specific discharge location.  Refer to the L_TYPE to see which facility feature was mapped.

Maintenance

The MassDEP Major Facilities datalayer is maintained by the MassDEP Bureau of Waste Prevention. A regular update schedule has not been determined at this time. Updates may include improvements to mapped facility locations and/or the location of major facilities not included in the datalayer at this time. Updates may also include additional facility types and an altered database structure.

In January 2013, 1,724 features include refined locations and updated classification information presented in the "major" fields: AIR, GWD, HWR, LQG_MA, LQG_RCRA, LQTU, TSDF, SWD.  Currently 59% of Large Quantity Generators of MA Regulated Waste (LQG_MA) and 100% of the other "major" categories have been located.
