Itogon Mayor Victorio Palangdan called on Congress to impose a limit on the period allowed for owners of mineral claims in the country.
The Benguet politiko explained there are many abandoned mineral claims that cannot be used for other purposes.
Palangdan said the government must still secure consent from owners of sites with abandoned mineral claims before they can be converted into other uses.
He said that having a prescribed period of time for mineral claims will force owners to maximize the use of the site.
Otherwise, he explained, the sites should be reverted to the State.
