Do you want to carry out certain building projects or activities such as:
- erect or modify a construction;
- begin operating an industry, perform an activity or use an industrial process;
- increase services or production of a good?
You are probably required to respect Article 22 of the Loi sur la qualité de l'environnement (LQE) and a certificate of approval must previously be obtained, if there will likely be emissions, a deposit, leaking or discharge of contaminants into the environment or modification to the quality of the environment.
Contact-us, Environnement ESA can help you to write your certificate of approval request.
