• Ground cover is restored as soon as practicable;
• All ground cover is maintained with the appropriate perennial species; and
• Weed management is undertaken in accordance with the Site Biodiversity Management Plan Section 7.22.
Tesla will consult with a local horticulturalist to ensure that perennial species to the site are maintained and/or replaced because of site disturbance. Tesla EHS team will be responsible for implementing this action in consultation with Edify Energy. This remediation specifically relates to operational disturbance and is not intended to be taken as a decommissioning commitment.

ENVIRONMENTAL NOISE
Tesla Megapack has a maximum noise emission level of 75dB when measured at a distance of 10 meters from any side surface of the enclosure, while operating at full maximum thermal system thresholds. These maximum operating conditions are rare and the typical noise emissions from the Megapack are much lower.
The RESS site maintains a minimum of 10m Asset Protection Zone (APZ) around all battery cabinets, and the nearest (residential) property is 440m away. An outline will be provided below to demonstrate how the Megapack installation will not impede upon these nearby premises.
Megapack can emit a maximum of 75 dBA at 10-metres from and side surface of the enclosure, while operating at full power (reference; Tesla Design and Installation Manual, 2023). Maximum power is only utilised in rare circumstances and this typically occurs when ambient temperature has reached (or exceeds) 50°C. The region of Griffith (and by proximity, Darlington Point), has never reached this temperature1.
As part of this project, the maximum allowable night-time threshold is 35dB when measured in LAeq,15min. For these calculations, a conservative figure of 60% fan duty has been estimated for RESS, given the historical weather trends for the area. This has then been mapped against the local nearby receivers. Operating the fan duty at 60% drops the operational noise from 75dB to 68dB.
Operational noise levels for the DPSF from Arup (2018), RESS facility and the cumulative noise levels from the site have been previously mapped against nearby receivers2, and the results have been described below (full results can be obtained from the below mentioned reference document). This uses the conservative 60% fan duty estimation as the noise emission level. The results below show that the calculated cumulative noise emissions from DPSF and the RESS facility are below the noise thresholds, even under worst case atmospheric and operating conditions.
