Paragraph 9 briefly describes duet control measures to be perfontw_d during
periods of operation. Emission Permit 91ME373F-2 currently details a Fugitive
Particulate Flnissions Control Plan (enclosed) for the existing gravel miring
operation. It should be noted that this permit is in the "Initial Approval"
stage which allows certain elements to be changed before preceding to the
"Final Approval" stage. A final approval inspection will be carpleted later
this spring after the source resumes activity.
According to the petitioner, material stockpiles are stabilized with a
chemical surfactant while the graveled haul roads are primarily controlled for
dust by application of magnesium chloride. Mr. Logue failed to include these
details in Paragraph 9 of Page 6. These dust control methods are considered
to be acceptable and can be used instead of frequent (i.e. daily) watering.
It should also be noted that the source is subject to a 20% opacity limit and
no off-property transport of visible emissions as per Regulation No. 1. of the
Colorado Air Quality Control Commission Regulations. The screener is subject
to the 10% opacity standard required wider New Source Performance Standards
for Nonmetallic Mineral Processing Plants.
Finally, this Department does not consider the propos expansion f the
mining area to require a separate permit from 911.1E373F-1, a proposed
expansion will be reflected in the final approval inspection report to be
submitted to the Air Pollution Control Division/Colorado Department of Health.
