When such exemptions are granted to an organization which represents Contractors in a specific trade from the 1 to 5 ratio on a local or statewide basis the member contractors will not be required to submit individual applications for approval to local joint apprenticeship coftmuttees, provided they are already covered by the local apprenticeship standards. A Contractor to wham the contract is awarded, or any subcontractor under him, who, in performing any of the work, under the contract, employs journeymen or apprentices in any apprenticeable craft or trade and who is not contributing to a fund or funds to administer and conduct the apprenticeship program in any such craft or trade in the area of the site of the public work, to whid'i fund or funds other contractors in the area of the site of the public work are contributing, shall contribute to the fund or furls in each craft or trade in which he employs journeymen or apprentices on the public work in the same amount or upon the same basis and in the same manner as the other contractors do, but where the trust fund administrators are unable to accept such funds, Con-tractors not signatory to the trust agreement shall pay a like amount to the California Apprenticeship Council.
