This Government Decision approves a comprehensive Regulation governing the organization and provision of public services for issuing integrated environmental authorizations and environmental authorizations for industrial and economic activities. It establishes the legal and operational framework for authorization procedures, including the use of information systems, data protection, and security of information. The text situates the Regulation within a broad normative context, expressly linking it to legislation on industrial emissions, water, waste, air quality, public services, state control, personal data protection, trade secrets, and the national pollutant release and transfer register. It sets out guiding principles such as legality, transparency, equality of treatment, quality, proportionality, user centricity, digital by default, simplification, and the use of a one stop shop. The Regulation defines the actors involved (Environmental Agency, Inspectorate for Environmental Protection, other competent authorities, and the interested public) and details the rights and obligations of both the Agency and applicants/authorization holders. It regulates in detail the steps for requesting, processing, issuing, refusing, suspending, withdrawing, re examining, updating, and extending authorizations, including the content of technical dossiers, specific information required for medium combustion plants, and the integration of environmental impact assessment and ecological expertise outcomes. It introduces the obligation to prepare and implement alignment plans, sets validity periods (12 years for integrated authorizations and 6 years for environmental authorizations), and provides for cost recovery through state fees based on a separate methodology, while prohibiting additional administrative charges. The text also establishes electronic registers of applications and authorizations, mechanisms for public information and participation, and procedures for tacit approval where certain opinions are not issued in time. Implementation is organized around a one stop shop model with front office and back office functions, multi channel access (online via SIA GEAP and EVO portal, and physical counters), and interoperability with other public registers via the MConnect platform. The Regulation prescribes internal management rules for human resources, monitoring and evaluation of authorization processes through performance indicators (efficiency, effectiveness, quality), annual reporting and public debates, and feedback mechanisms. It sets out detailed procedures for complaints and pre contentious challenges, including formats and deadlines, and clarifies the division of competences between the Environmental Agency and the Inspectorate for Environmental Protection. Finally, it addresses liability and sanctions for officials and authorization holders, including responsibility for environmental damage and health impacts, and allows for suspension of authorization processes under states of emergency, siege or war.
