SEPA is authorized to handle examination and approval of environmental impact reports for certain types of projects: 1. Projects that have a so-called special nature, such as nuclear facilities or top-secret projects. 2. If the project crosses the border between two provincial-level regions. 3. If the project entails examination and approval of the project at the national level. SEPA will also handle a number of aspects of the implementation of the law. These aspects include governing qualifications of EIA service providers, classification of construction projects, and examination of special plans.
