A bill to amend the Environmental Public Health Act was introduced in Parliament yesterday, setting the stage for a new compulsory licensing regime for the cleaning industry.

If passed, all cleaning companies must pay their workers according to a tiered wage system as part of the licensing requirement.

The law will not specify these tiered salaries, which will be negotiated by a committee of unionists, employers and government officials.

Earlier this month, the Government announced that with the change, a full-time indoor cleaner would earn at least $1,000 a month, up from about $850 now.

Those who handle cleaning machines will earn at least $1,400, and a supervisor at least $1,600.

The Bill also proposes a change to help the National Environment Agency (NEA) better pinpoint and catch those who litter from vehicles or flats. Car owners and drivers, as well as flat owners and occupiers, will have to provide information which may lead to identifying a litterbug, when asked to do so by the NEA.

Six other Bills were introduced yesterday.

They were the Public Order (Additional Temporary Measures) Bill, Singapore Tourism Board (Amendment) Bill, Land Titles (Amendment) Bill, Rapid Transit Systems (Amendment) Bill, Air Navigation (Amendment) Bill and Singapore Institute of Technology Bill.

The Rapid Transit Systems (Amendment) Bill will raise the maximum overall financial penalty for rail incidents or regulatory breaches.

The proposed new maximum is $1 million, or 10 per cent of the operator's annual fare revenue from running the rapid transit system, whichever is higher. The current maximum penalty is $1 million.
