Enterprises whose size and polluting potential are not as significant have their environmental licensing carried out through simplified studies, based on the preparation of a Memorial of Characterization of the Enterprises (MCE), a Report of Characterization of the Enterprises (RCE) or even a Simplified Environmental Study (EAS). In this case, it is generally not necessary to collect primary data, all that is needed is the protocolization of specific documents and forms, and the presentation of secondary socio-environmental data to obtain the Prior License (LP).
