4.17 AIR RESOURCES PROTECTION
The Southfield Mine is in reclamation only status since operations permanently ceased
in 2000. EFCI commenced reclamation activities at the mine site in 2001, demolishing
surface facilities and sealing mine openings. By 2001, backfilling, regrading, and
topsoil replacement was completed according to plans approved by the DRMS. All air
emission permits for the mine site are no longer required and have been terminated.
The coal loadout site located near Florence, Colorado, was similarly reclaimed in 1997,
including permanent seeding completed during the same year. All air emission permits
for the loadout site are no longer required and have been terminated.
4.17.1 FUGITIVE DUST
EFCI currently holds eight (8) air emissions permits from the Colorado Department of
Health, Air Pollution Control Division, with six (6) of these permits covering the mine
and the remaining two (2) permits covering the loadout area. These permits are
presented in this application in Exhibit 41 Other Permits.
Specific measures designed to effectively control fugitive dust emissions are an
integral part of EFCI's mining and reclamation plans.
Detailed discussions of control measures implemented by EFCI to minimize fugitive
dust emissions are contained in Section 2.05.6, Mitigation of Surface Coal Mining
Operation Impacts and the following sections.
4.17.2 CONTROL MEASURES
EFCI currently and will continue to utilize fugitive dust control measures to ensure
compliance with Federal and State air quality standards as outlined in the above
referenced section. Specific control measures include the following:
o All conveyors are fully or partially covered
o All transfer points are enclosed
o Coal preparation involves wet processing and is conducted within
the closed preparation plant building
