The company operating a pellat plant in Atikokan is being asked to repay a portion of a grant it received two years ago from the Northern Ontario Heritage Fund.
Rentech recevied $4-million to assist with the opening of plants in Wawa and Atikokan.
The company shutdown its Wawa facility in February.
Rentech says the Heritage Fund Corporation is seeking repayment of $2.5 million dollars as a result.
The company says it was notified by the Heritage Fund this month that by not having the Wawa facility operating, it did not fullfull its commitments under the grant agreement.
