Voluntary – 43 CFR 3809 Plan of Operations Form
11. Hazmat: include information such as, but not limited to, type of generator, chemicals, fuels, quantities, disposal,
storage, etc. If chemical processing plants are proposed in site operations, be sure to include tank capacities and
operating solution volumes. Indicate locations of use and storage of hazardous materials on location map(s) in
Exhibit III.
12. Rock Characterization and Handling Plans: Please include the following information and note N/A if something
doesn’t apply to the proposed operation. Depending on the proposal, these details may be minimal or very
detailed.
II.
Materials Characterization Plan must encompass:
1. Waste rock
2. Ore
3. Tailings
4. Pit wall and floor rock
5. Pit backfill rock (dry/wet scenarios)
6. Cap/cover materials (identified site specific sources)
III. Approach/Procedures for Characterization
1. Statistical Approach to Characterization (define statistical adequacy) to include:
a. Sample selection
b. Number of samples
c. Quantity of material
d. Review by BLM/CDRMS
2. Characterization Procedures
a. Sample selection
b. Identify by rock type/final disposition (ore, waste, pit wall, pit floor, backfill, etc)
c. Record locations (both surface and at depth)
d. Mineralogical analyses such as XRD, XRF, Petrology, Petrography, etc.
e. Static testing – (required for ore, waste rock and tailings) such as Acid-Base Accounting, Net
Acid/Alkaline Production, net carbonate value, etc.
f.
Kinetic testing (required for ore, waste rock and tailings but not for metallurgical ore recovery)
such as Humidity cell/column leach
IV. Cap/Cover Geotechnical Protocols (may include waste rock, spent leach, etc) to include:
1. Grain Size
2. Atterburg limits
3. Initial moisture content
4. Dry bulk density
