Environmental authorisation & official documents
Documents obtained from the official administrative file are provided here with short explanations. Formal authorisations and decisions are official public acts. The acoustic studies, technical reports and manufacturer material were prepared by third parties and form part of that file. The Spanish originals remain authoritative.
Newly disclosed material: the file now includes acoustic studies from 2018 and 2020, a 2024 measurement report and technical kart documentation. These records raise important questions about whether the assessment reflects the full fleet and normal busy operation.
Environmental authorisations
Environmental authorisation AAU/MA/04/18
Original authorisation containing environmental and operating conditions, including kart-track hours. Why it matters: this is the principal source for the year-round 14:00–16:00 closure and the winter closing time of 20:00.

2026 modification of AAU/MA/04/18
Official modification issued in 2026. Read together with the original authorisation. Why it matters: it records later changes but does not replace the need to read the original operating conditions.

Acoustic and kart documentation
2018 acoustic study
Initial study dated 30 January 2018. Why it matters: it provides the original acoustic assumptions, but was later cancelled and replaced by the 2020 study.

2020 replacement acoustic study
Study dated 24 February 2020 and submitted by the operator on 27 February 2020. Why it matters: this replaced the 2018 study and is central to understanding the assumptions used to authorise the activity.

2024 acoustic measurement report
Report based on measurements taken beside the road on 11 June 2024. The report is dated 13 June 2024 and was registered on 1 July 2024. Why it matters: it reports 59 dB against a 60 dB limit, based on three five-second operational samples and an instrument uncertainty stated as ±2 dB.

Kart technical sheets and manufacturer documentation
Technical information supplied for the karts, including the exhaust silencer or dB-killer statement. Why it matters: it should be compared with the actual fleet in use, including different models and two-seater karts.

Other official material
Evidence submitted with the complaint
These two short records identify timestamped video evidence of apparent operation during the year-round 14:00–16:00 closure. They are separated from the official documents to avoid confusion.
