Environmental Practitioner Licensure
The Environmental Practitioner Licensure Program certifies, licenses and regulates environmental health professionals in the Asbestos, Lead, Septic, and Sanitarian disciplines. These licensed professionals protect human health and the environment by operating within the constraints of the regulations and using “state-of-the-art” practices. The Program's main charge is the management and enforcement of the assorted licensing regulations for environmental health practitioners and training providers.
This office does not meet with visitors who do not have a scheduled appointment. A drop-box is available at the 1st floor security desk at 410 Capitol Avenue should individuals wish to submit applications, fees or any other documents. It is strongly recommended that all applications be submitted via U.S. Mail. Cash is not accepted.

However, no touching or taking of samples is permitted without a certificate as an inspector. A person who conducts a visual inspection to determine whether a response action is complete shall be certified as a project monitor.
Asbestos Project Monitor: Certification as a project monitor authorizes a licensed asbestos consultant to function in the capacity of on-site representative of the facility owner or other persons, interpret project specifications or abatement management plans, monitor and evaluate contractor or employee compliance with applicable regulations or specifications and ensure that abatement projects are properly conducted and completed. The project monitor shall not also function as the asbestos contractor or as an employee of the asbestos contractor on the same asbestos abatement project for which he is the project monitor.
