Any member with eligible service prior to the effective date of membership may purchase up to 10 years of such service upon certification of his fire department or emergency medical services agency. Such purchase shall be prorated at the rate of one year for every two years of eligible service. The cost of such service shall be an amount as established by the Board. Notwithstanding any other provisions of this chapter, the Board may grant qualified prior service credits to an eligible volunteer firefighter or eligible volunteer emergency medical services personnel, under such terms and conditions that the Board may adopt, if the Board determines that such volunteer has been denied such prior service credit through no fault of his own.
