Port Augusta's coal-fired electricity industry has reached its final curtain call with the demolition of the former power station site reaching completion.
The four year process has seen the execution of eight major charge-felling events, the removal of 75,000 tonnes of scrap steel and the safe disposal of over 1000 tonnes of asbestos-containing material.
Some 100 full-time workers were employed over a 30-month period at the height of the works program.
"I would like to personally thank every single person who has worked on this complex closure program," Flinders Power CEO Peter Georgaris said.
"To complete the work on time, on budget and most importantly, safely, is testament to their commitment and professionalism.
"Thanks must go also to the members of the Community Reference Group for their time and contribution over the last two years, and to the broader Port Augusta community for its support throughout the closure.
Completion of the site includes rehabilitation of the ash storage area and former coal stockpile, where over five tonnes of native seed have been planted.
Extensive site contamination investigations were also undertaken, with over 3000 soil and groundwater samples taken for analysis.
Four localised areas that had been impacted by historic hydrocarbon spills have been excavated and bioremediated at the site, and an independent site contamination auditor has produced a report for the EPA
Some infrastructure has been retained to facilitate transition to future land use, including the rail loop, unloading facility, roads, two workshop buildings, and water and diesel storage.
Flinders Power have now turns its attention to the settlement process and land transfer ownership to Cu-River.
Cu-River announced plans earlier in the year to transform the site into a $250 million port facility capable of handling iron ore, grain and other commodities.
The company will take over responsibility for ongoing environmental management at the site, including the transfer of the EPA Licence obligations.
Settlement and land transfer is expected to occur later this month.
