The Pension Committee established in Section 210.03(b) shall have general responsibility for the administration and interpretation of the Plan, including, but not limited to, complying with reporting and disclosure requirements and establishing and maintaining Plan records. The Committee shall engage the actuary and such certified public accountants, who may be accountants for the Borough, as it shall require or may deem advisable for the purposes of the Plan. The Committee may, with the approval of the Borough Council, adopt amendments which, upon the advice of counsel, it deems necessary or advisable to comply with the law or to facilitate the administration or management of the Plan, and which, in the opinion of the actuary selected by the Committee, do not significantly increase the then currently estimated costs of the Plan.
