BACKFILLING AND GRADING.
Upon completion of gravel removal from an area, backfilling and grading can commence.
The material to fill the open pit is moved by scrapers from nearby active pit areas or from
overburden stockpile. Acid-forming and toxic producing materials do not exist on the site
and therefore will not constitute a problem. The backfill material is placed, compacted,
• and graded by scrapers andlor tracked dozers.
