Automatic summary, not yet reviewed
- The law requires an environmental assessment of any plan, program or project that could have significant effects on the environment before it is approved or authorized. If the assessment is not done, the approval or authorization is invalid.
- It creates two types of assessment: strategic assessment, for plans and programs, and impact assessment, for projects. Each can be ordinary or simplified, depending on how serious the possible effects are.
- It sets maximum deadlines so procedures do not drag on: 22 months for ordinary strategic assessment, 4 months for the simplified one, 4 months for ordinary impact assessment and 3 months for the simplified one.
- If a public body that was consulted does not issue its report, the procedure can continue if the environmental body has enough information to decide. This prevents a missing reply from stalling the process.
- Administrative silence never counts as a favorable assessment. If the environmental statement or report is not issued on time, the project is not considered to have passed the assessment.
- Impact assessment statements expire if the project has not started within 4 years of their publication, though a 2-year extension can be requested.
- It sets penalties for starting work without the prior assessment or breaching its conditions: fines of up to €2,404,000 for very serious offenses, plus possible compensation and bans on contracting with the government.
- It regulates nature conservation banks, a voluntary mechanism to offset, repair or restore losses of natural values through credits that can be bought and sold.
Who it affects
- Project developers (companies and individuals): They must have their projects environmentally assessed before getting authorization, a responsible declaration or prior notice, and they face penalties if they fail to comply.
- Public administrations: They must process assessments within the set deadlines, consult the affected authorities and publish their decisions.
- The general public: People can take part in public information procedures and review the documents in these proceedings.
- Nonprofit environmental associations: They can be consulted as interested parties if they have been legally established for at least two years and work to protect the environment.
