What are Overburdened Communities?

What are Overburdened Communities (OBC)?

NJ’s EJ Law creates a definition to screen populations who are potentially in need of environmental justice.

Overburdened Communities (OBC)

The State has updated mapping of New Jersey’s OBCs, as required by the Act (see the Overburdened Communities tab above). Specifically, OBCs are block groups with:

  1. At least 35 percent low-income households; or
  2. At least 40 percent of the residents identify as minority or as members of a State recognized tribal community; or
  3. At least 40 percent of the households have limited English proficiency

Census block groups with zero population and located immediately adjacent to an OBC are labeled as “adjacent.” Existing or proposed facilities located in adjacent block groups may be required to conduct further analysis in accordance with the Environmental Justice Rules.

Data from the 5 Year American Community Survey (2018 to 2023)

EJMAP

EJMAP provides the public a visualization of OBC locations throughout the State, where existing facilities regulated under the law are located and what existing environmental and public health stressors currently impact these OBCs. Watch this tutorial to learn more about EJMAP.

DEP has updated EJMAP with new stressor data. Any permit application submitted on or after 1/31/25 must refer to this data for analysis and permitting purposes. The previous dataset will remain as an archived layer in EJMAP.

To learn what stressor data was updated in EJMAP, visit the January 2025 EJMAP Data Update . For details of underlying calculations behind EJMAP, please read the accompanying EJMAP Technical Guidance.

For more information on the previous versions of EJMAP documentation and data, please visit the EJMAP Data Documentation page.

Feedback on the tool and technical guidance, particularly related to the structure and functionality of the tool itself, can be shared to EJMAPFeedback@njdepwptest.net for consideration.
