Sometimes reclamation starts while a mine is in operation. Known as 'segmental reclamation', DNR encourages mine owners to reclaim parts of the mine as they are finished working them. This helps to control erosion, the spread of noxious weeds, and prevent blowing dust. Also, it spreads the cost of reclamation for the mine owner out over time.

Known reserves of perlite will be available for many generations. In the past 60 years less than 1% of the reserve base has been used. [2] Perlite mining has little overburden to manage and minimal waste. No chemicals are used in processing perlite. Perlite mining has limited environmental impact.
The Surface Mining Act is a reclamation law that requires a permit for each mine that: (1) results in more than 3 acres of mine-related disturbance, or (2) has a high-wall that is both higher than 30 feet and steeper than 45 degrees (RCW 78.44, chapter 332-18 WAC.Local governments must formally approve mine sites and/or the subsequent use of the mine site (RCW 78.44.091) …
The company started its activities in 2006 with main operation areas including perlite mining, crushing, screening and processing. The perlite ore extracted from the licensed perlite sites which have highly abundant perlite reserves are at a level to compete with all global perlite deposits in terms of both quality and expansion rate.
Illegal mining is a significant issue for the industry so preventing illegal or unregulated mining operations will help ensure that all mining is bound by the same environmental standards and ensure accountability. Economical viability. Mine development starts when a deposit is discovered and continues through to the start of construction.
