plan(s) addressing stabilization and reclamation of Little Deadwood Gulch at the Chief
Portal and May Day 2 areas, stabilization of the Chief Portal, stabilization of the access
road immediately above the Chief Portal, and the Division approves the as built
certifications submitted subsequent to the completion of the approved plans. The Chief
Portal was constructed illegally and addressed under Violation MV- 2010 -020.
This issue may require coordination with other agencies, including but not limited to,
the WQCD, COE, EPA, and USFS.
3. Mining and Milling activities may not commence until the Division receives and
approves, through the Technical Revision or Amendment process, the revised work
plan(s) addressing stabilization of the collapsed adit at the May Day 1 area, construction
of a new portal and mill facility in accordance with the Act and Rules, and the Division
approves the as built certifications submitted subsequent to the completion of the
approved plans. The portal and mill facility were illegally constructed and addressed by
Violations MV- 2009 -035 and MV- 2010 -001.
This issue may require coordination with other agencies, including but not limited to,
the Mine Safety and Health Administration (MSHA) and USFS.
4. Mining and milling activities may not commence until the Division receives and
approves, through the Technical Revision or Amendment process, adequate information
for ambient surface and ground water quality for the Division to verify hydrologic
baseline conditions, and a hydrologic monitoring plan has been fully approved by the
Division and implemented by the Permittee as necessary for the Division to verify
compliance with water quality regulations and the Act and Rules. The Applicant has
commenced the required monitoring of surface water and has proposed the locations

This issue may require coordination with other agencies, including but not limited to,
the USFS.
