ITP Developments has applied to change conditions to the solar farm's planning approval that would given them six months rather than three to clear the site.

It is also seeking to remove a clause that would require them to maintain landscaping on the site after the plant closes.

The $8.9 million project on farm land about six kilometres out of Orange on Molong Road is expected to have a life of about 25 years.

A staff report to Tuesday night's meeting of Orange City Council has recommended the modifications be approved.

"Council staff raise no objection to the additional three months for decommissioning of the site and is considered reasonable due the systematic nature in which the infrastructure needs to be removed from the site," it said.

"The underlying intent of this condition was to ensure that the site is suitably rehabilitated and within a suitable timeframe. This intent will be maintained."

And it said a review of other solar farm approvals by the Western Regional Planning Panel showed decommissioning periods of up to 18 months.

The report also recommended the operators maintain the landscape until the decommissioning was complete.

The changes were put on public exhibition and received two objections from the public.

One said they were concerned about how the waste would eventually be removed.

It suggested the company pay the council a surety of $1.75 million to cover the work.

"Who is going to be the watchdog to ensure all these conditions are met?" it said.

The other objection said they were concerned the company would not maintain landscaping in the latter years of the operation.

"If for example a period of drought prevailed, the effects of which were not obvious immediately, and any suffering plants not replaced or maintained for the long term."

Council opposed the solar farm's planning approval last November but the Western Regional Planning Panel approved it.

The site is outside the state government's Central West Orana Renewable Energy Zone.
