15. Outfalls - For each process water outfall, provide a description of:
all operations contributing wastewater to the effluent, including water associated with product crushing or washing,
equipment washing, sanitary wastewater, groundwater;
- the average flow contributed by each operation;
- the treatment received by the wastewater, including an identification of any chemical additives used.
Use additional pages as needed.
*MGD - Million gallons /day
**If sediment pond, indicate approximate volume of water.
16. Water quality data: Analytical data for the following parameters shall be submitted for at least one grab sample from each
discharge point. If no water is currently available for analysis, so indicate.
Alkalinity (mg/1) XXX pH (s.u.)
Total Dissolved Solids (mg/1) COD (mg/1)
XXX Total Suspended Solids (mg/1)
XXX Oil and Grease (mg/1)
No water to analyze at this time
The Division may request analysis of other parameters once the application has been reviewed.
17. Activity duration: When did the activity commence? Mining started in late 2006 and is approximately 50% complete.
What is the estimated life of the activity from which the discharge(s) identified in item 15 originate? Approximately 4 to
12 months to complete mining depending upon market conditions. Site will remain active thereafter as receiving area for
off -site plant fines to create constructed wetlands.
