Between a declaration and a full environmental impact study there are two years and an order of magnitude in cost. That decision is taken before anyone is hired, and it is almost never taken with advice.
The cost of environmentally assessing a project in Chile doubled in four years. Timelines followed: a full impact study that took 355 days in 2008 now takes more than a thousand.
Against that, permitting architecture — which instrument is used, how the project is defined, in what order sectoral permits are filed — matters more than the quality of the study that follows. And once filed, it cannot be changed without withdrawing and starting over.
In September 2025 Ley 21.770 came into force, introducing up to eight years of regulatory stability, alternative authorising techniques and positive administrative silence. Its regulations are being written now. The learning curve for the entire market reset to zero.
With written reasoning and the argument that sustains it if the environmental authority challenges the choice.
With dependencies and critical path: which can run in parallel and which block the rest.
Whether the project qualifies for regulatory stability, whether an alternative authorising technique applies, and where positive administrative silence can be invoked.
Written and ready to submit.
Identified by name and by agency, and what to do about them starting now.
With the technical criteria the sponsor should require.
