The Environmental Research and Radiation Safety (ERRS) Department was previously a Unit under the Department of Compliance and Enforcement, primarily charged with the responsibility of conducting environmental research and routine monitoring of environmental media (Water, Soil, Radiation, Air, and Noise) across Liberia. Elevated to a department in January 2022, ERRS has positioned itself as the powerhouse of scientific investigations and pollution abatement at the Environmental Protection
Agency (EPA). of Liberia. The goal of the Department is to obtain empirical analytical data that helps inform policy formulation to abate future environmental disasters, reduce pollution risks, and mitigate impacts associated with project activities on the environment and bio-receptors (humans, plants, and animals).

The Department issues chemical and radiation registration and importation licenses, chemical, and radiation importation clearances, effluent discharge licenses, chemical disposal licenses, and grants accreditations to analytical laboratories, health facilities, industries, and others for the possess and uses of chemicals and radiation sources consistent with Part IV Section 44 and Part IX Section 96 of the Environmental Protection and Management Law of Liberia. Additionally, the Department serves as the
Custodian of the Chemical and Radiation Registries and is responsible for reviewing quarterly and bi-annual monitoring reports submitted by proponents. ERRS Department also develops and implements research and development programs in support of environmental compliance monitoring, investigates existing and potential environmental problems, and provide public information and education (through the media and corporate communication unit) to encourage the participation of an informed citizenry in
environmental quality planning and monitoring.

The Environmental Research and Radiation Safety Department is headed by a manager and has three units: Chemical Management Unit, Environmental Monitoring and Research Unit and Radiation Safety Unit, each headed by an assistant manager.
