3. As a rule, the issuance of the ASV is conditional on the property being duly registered in the Rural Environmental Registry (CAR);
4. Prohibits the issuance of the ASV (a) in areas linked to the Environmental Reserve Quota title; (b) in rural properties whose registration in the CAR is suspended or canceled; and (c) in rural properties whose registration in the National Rural Registration System (SNCR) is not active;
5. Conditions the issuance of native ASVs by a municipal environmental agency or public consortium of municipalities to interventions with a local environmental impact that directly affect the territory of the respective municipality, located or developed in an urban area or area of consolidated urban expansion, as well as the cumulative observance of specific conditions (proof of technical capacity, existence of a municipal environmental council or equivalent collegiate body and availability of the authorizing act in the National System for the Origin of Forest Products – Sinaflor).

The Resolution will come into force 180 days after the date of its publication.
