8. (1) The amount of the payment that may be authorized under section 103 of the Act to an applicant who is the owner of the pollutant or the person having control of the pollutant shall be calculated so as to be equal to the lesser of, (a) the difference between, (i) the total liability of the applicant to other persons under Part X of the Act plus the amount of the cost and expense incurred by the applicant in respect of the other persons that is reasonable, in the opinion of the Corporation, in preventing, eliminating and ameliorating the adverse effects caused by the spill and in restoring the natural environment, and (ii) the total of the amounts recoverable in the opinion of the Corporation and the receipts by the applicant with respect to the spill, not including payments to or on behalf of the applicant by an insurer of the applicant, less the greater of, (iii) the applicable specified deductible, or (iv) the amount of insurance coverage the applicant has that is applicable to liability arising from the spill; and (b) the total liability of the applicant to other persons under Part X of the Act to a limit equal to the aggregate of the limits prescribed by subsection 10 (2) in respect of all spill creditors with respect to the spill plus the amount of the cost and expense incurred by the applicant in respect of the other persons that is reasonable, in the opinion of the Corporation, in preventing, eliminating and ameliorating the adverse effects caused by the spill and in restoring the natural environment.  R.R.O. 1990, Reg. 360, s. 8 (1). (2) Where the amount determined under clause (1) (b) would be higher but for the application of a limit prescribed by clause 10 (2) (b), the amount determined under clause (1) (b) may be increased by substituting for the said limit the amount paid by or on behalf of the applicant to the spill creditor under a policy of insurance.  R.R.O. 1990, Reg. 360, s. 8 (2). (3) The amount that would otherwise be authorized for payment under section 103 of the Act to an applicant who is the owner of the pollutant or the person having control of the pollutant shall be reduced by an amount equal to, (a) the amount of any loss, damage, cost or expense in respect of the spill that could have been prevented by the applicant if the applicant had carried out the duty under subsection 93 (1) of the Act to do everything practicable to prevent, eliminate and ameliorate the adverse effects of the spill and to restore the natural environment; and (b) the amount of any loss, damage, cost or expense in respect of the spill that could have been presented if the applicant had complied with the lawful orders and the reasonable recommendations of all public officers with respect to prevention, elimination and amelioration of adverse effects and restoration of the natural environment.  R.R.O. 1990, Reg. 360, s. 8 (3). (4) Where an applicant under subsection (1) is insured by a policy of insurance in a form, filed with the Corporation and accepted for the purpose, providing coverage for at least the amount of the specified deductible and that defence costs are subject to the limits of the insurance, the defence costs paid under the policy of insurance for the claims that are the proper subject of the application shall be part of the total liability referred to in subclause (1) (a) (i).  R.R.O. 1990, Reg. 360, s. 8 (4).
