In such event the Department of Mines and Mineral Industries shall construct ditches, flumes, backfill stripping pits and cropfalls, and improve stream beds for the purpose of preventing the flow of surface water into mines, and shall purchase the necessary materials for the same, and also shall purchase and install pumps, pipes, machinery, equipment and materials for the purpose of pumping water from abandoned mines, and shall seal abandoned coal mines and fill voids in abandoned coal mines in those instances where such work is in the interest of public welfare: Provided, however, That the Commonwealth shall not bear any operating and maintenance costs whatsoever other than one-half of the power pumping costs and shall not bear the installation costs of any underground facilities; however, this restriction shall not apply and shall not pertain to cases of emergencies endangering life created by the flooding of mines, nor shall the functions herein set out be restricted to abandoned mines in cases of such emergency.
In such instances, upon the prior determination by the Secretary of Mines and Mineral Industries when the Secretary of the Interior of the United States of America operating under the Federal companion legislation has likewise ruled that an emergency exists, the Department of Mines and Mineral Industries shall:
Anything to the contrary herein notwithstanding upon the prior determination by the Secretary of Mines and Mineral Industries that water in an abandoned mine or in abandoned mines threatens the safety of the residents of the area or threatens widespread subsidence and damage to large amounts of property, the Department of Mines and Mineral Industries, without the need for joinder by the Federal Government and without the need to secure a sponsoring agency to maintain and operate any of the facilities shall have the authority to:
Under no circumstances may any funds be used the object of which or as a result of which any mining operator or company will be relieved of his or its pumping obligations or any part thereof.
The aforesaid determination and action taken thereby may not in any way be construed as relieving any party of its obligations or responsibilities as to the disposition of mine waters.
