7May 18, 2006 Final Rule
- Phases in final DPM PELs over two years
- 308EC µg/m3 - effective May 20, 2006
- 350TC µg/m3 - effective January 20, 2007
- 160TC µg/m3 - effective May 20, 2008
- 1st step, 308EC µg/m3, is an EC limit
- 2nd 3rd steps are TC limits
- Will use 1.3 conversion factor for 350TC µg/m3
limit as we did under the Settlement Agreement
and use EC to validate - MSHA will initiate separate rulemaking to convert
160 TC limits to comparable EC limits
8May 18, 2006 Final Rule
- Deletes provision restricting newer mines from
applying for Special Extension - Effective August 16, 2006 - Medical evaluation to
determine miner's ability to wear a respirator
and transfer of miners unable to wear a respirator
9Respiratory Protection(New Provisions)
- Applicable when respiratory protection is
required - Confidential medical evaluation required to
determine miners ability to use a respirator - Must conduct before fit testing or use at mine
- No cost to miner
- Evaluation must be by physician or other licensed
health care professional (PLHCP) - If PLHCP determines miner is unable to wear
negative pressure respirator, PLHCP must also
evaluate miners ability to wear powered air
purifying respirator (PAPR)
10Respiratory Protection(New Provisions)
- Mine operator must insure miner has opportunity
to discuss their evaluation results with the
PLHCP before the PLHCP submits written
determination on miners ability to wear
respirator to the mine operator - If miner disagrees with PLHCPs evaluation
results, the miner has 30 days to submit
additional evidence regarding their medical
condition to the PLHCP
11Respiratory Protection(New Provisions)
- Mine operator must obtain written determination
from PLHCP regarding miners ability to wear
respirator - Mine operator must assure that PLHCP provides
copy of determination to miner - Reevaluation required whenever mine operator has
reason to believe conditions have changed which
could adversely affect miners ability to wear
respirator
12Respiratory Protection(New Provisions)
- Upon written notification that PLHCP has
determined that miner is unable to wear
respirator, miner must be transferred to work in
existing position in area of same mine where
respirator is not required - Transfer must be within 30 days of final
determination by PLHCP
13Respiratory Protection(New Provisions)
- Miner must continue to receive compensation at no
less than regular rate of pay in the
classification held by the miner immediately
prior to transfer - Increases in wages of the transferred miner based
on new work classification - Mine operator must maintain records of identity
of PLHCP and the most recent determination of
each miners ability to wear respirator. Records
must be kept for duration of miners employment
6 months

respirator wearers and transfer of miners unable
to wear a respirator - Rulemaking to convert TC final limits to
comparable EC limits
