In Guatemala the Environmental Regulation on Assessment, Control and Monitoring (Governmental Agreement No. 431-2007 ECSA) regulates the EIA system. This is the regulation that governs the area and its provisions. It contemplates the procedures to be followed in the processes of evaluation, control and environmental monitoring, which are mandatory for all new and existing activities.
This regulation has an emphasis on EIA, but SEA appears as one of the instruments (art. 12).
This regulation (article 3, title III. Definitions and article 14 of title IV) defines SEA as:
A process of environmental impact assessment that is applied to plans and programs. By its characteristic and nature, this type of process can be applied to plans and programs that are important at national, bi-national, regional, or Central American levels, or by multilateral agreements, in accordance with this regulation.
