Narrative Description of Best Management Practices
Best Management Practices (BMP) In Place
A concrete floor and containment berm around the fueling area.
2. Use of oil absorbent in areas where drips and minor spills may occur.
3. Proper handling and disposal of waste oil, oil absorbent and oil filters.
4. A Spill Prevention Plan developed and implemented.
5. Covered drum storage area.
6. All materials stored outside are properly sealed and labeled.
7. Clean-up materials and tools are available for use in the event of spills or
leaks.
8. Signs posted in appropriate areas to encourage good housekeeping.
9. Clean ditches as required to remove vegetation and debris.
10. Request crude mica supplier to maintain moisture levels as low as possible
to reduce seepage.
11. Concrete containment with retaining walls for the crude mica stockpile.
The K-Mica shed and the scrap storage area have been eliminated as
satellite mica storage areas to prevent mica from being carried out into the
43 outfall by the stormwater.
12. Utilize sprinklers on the crude mica stockpile to minimize any mica from
blowing out of the pit.

CHANGES IN INDUSTRIAL ACTIVITIES
The K-Mica shed and the scrap storage area have been eliminated as satellite mica storage areas
to prevent mica from being carried out into the 43 outfall by the stormwater.
