Your proposed rule edit for Gruta do Limoeiro includes detailed operational guidelines for drone pilots, referencing DECEA's ICA 100-40 regulations. However, to ensure accuracy and reliability, it is important to reference official sources that confirm these regulations. Additionally, the outline provided is a general polygon; a more precise outline representing the actual area of the cave would enhance the rule's effectiveness.

Located 15 km from downtown Castelo, Espírito Santo, the Gruta do Limoeiro is the most important geological and archaeological site in the state. It consists of a large cave system with multiple internal chambers featuring thousands-of-years-old limestone formations like stalactites and stalagmites. It is also a fragile scientific site where 4,500-year-old indigenous fossils have been uncovered. Because it is a confined, heavily protected environment managed through guided tours, recreational drone operations are entirely banned.  

Indoor Cave Flight (Zero Tolerance): Flying a drone inside the cave galleries is completely forbidden. The physical space is narrow, enclosed, and populated by tourists wearing mandatory safety helmets. A drone crash inside could permanently destroy delicate, irreplaceable speleothems (rock formations) or cause severe injuries in the dark.  Ecological Disruption: Caves are sensitive ecosystems that serve as natural habitats for bat colonies and specialized micro-fauna. The high-frequency noise and LED lights of a drone cause severe ecological stress and disrupt the local wildlife.External Restrictions: Even outside the cave's entrance, the site functions as a formal tourist and environmental reservation managed by the municipality. Under ANAC rules, pilots cannot fly within 30 horizontal meters of non-consenting people, which is impossible to maintain near the main entrance trail where tour groups gather.  Legal Penalties: Operating an unauthorized drone here violates state heritage protection laws and DECEA urban/tourist airspace regulations. Illegal pilots risk immediate grounding by site guides, permanent equipment seizure, heavy ANAC administrative fines, and criminal prosecution under Article 261 of the Brazilian Penal Code for endangering public safety.
