LANDFILL and waste management officials may or may not breathe a sigh of relief when odour specialists reveal their survey findings on Thursday night.
Residents are expected to pack a community forum when Environmental Protection Authority chief executive Barry Buffier will provide an update on an ongoing odour problem.
Independent odour expert Terry Schultz will discuss his findings at the sites since the investigations began earlier this month.
Landfill and waste management facilities representatives will attend.
While many residents say the smell has gone, some parts of St Clair are still copping it.
Kemps Creek facility SITA has adjusted its operations since it was fined $1500 in July.
"The weather has allowed us to manage our stockpile product," spokesman Simon Lee said.
"We're also managing the stormwater more efficiently to stop it going smelly."
"We've been very open with the EPA and encourage them to come on site. We may have contributed to the odour but ... we're 12 kilometres away from the affected areas."
Waste Management Assets Corporation, operators of Eastern Creek landfill, has been fined $3000 since May and is working to improve its performance.
"Odours from the operations at Eastern Creek are limited to the area around the landfill," a spokesman said. "In addition, there are at least six other waste management facilities within a 15-kilometre radius of the site with the potential to generate odours."
■ The forum starts 7pm. St Clair Leisure Centre is on Botany Lane, off Bennett Road.
