The disability retirement allowance of a local miscellaneous and local safety member whose effective date of retirement for nonindustrial disability is after June 14, 1975, and whose last employment preceding retirement was with an employer subject to this section shall be increased by an amount that, when added to the disability retirement allowance otherwise payable under this part will make his or her disability retirement allowance, exclusive of the annuity payable from accumulated additional contributions, equal to 30 percent of final compensation if he or she has five years of service plus 1 percent of final compensation for each year of service in excess of five years to a maximum of 50 percent of final compensation.

In no event shall the disability retirement pension be more than sufficient to make the disability allowance equal the service retirement allowance, exclusive of any annuity purchased by accumulated additional contributions, receivable by the member were he or she to continue in service and retire at age 60.

The added amount payable under this section shall be a liability solely of employers subject to this section. In the case of a member who has service with more than one employer, the liability for the disability retirement pension provided by this section shall be apportioned on the basis of the member’s service to any employers who have elected to be subject to this section.

This section shall not apply to any contracting agency nor to the employees of any contracting agency unless and until the agency elects to be subject to the provisions of this section by amendments to its contract made in the manner prescribed for approval of contracts, except that an election among the employees is not required, or, in the case of contracts made after June 14, 1975, by express provision in the contract making the contracting agency subject to the provisions of this section.

This section shall only apply to members who retire for disability on and after the date the agency elects to be subject to this section.
