AIR QUALITY STUDY PLAN
INTRODUCTION
Climatological information is required by
Rule 2.04.8 of the CDMG regulations which
states that "When requested by the Division
the application shall contain a statement of
the climatological factors that aze
representative of the proposed permit area. "
This requirement will be fulfilled by
meteorological data collected from a weather
station near Trinidad. As a result, no onsite
monitoring is anticipated.
Even though the Lorencito Project will
primarily be an underground mining
operation, there will still be surface
operations and activities. These surface
operations, as well as the mine ventilation
exhaust, will result in the release of
particulate into the atmosphere. As part of
the permitting process it is necessary to
determine the ultimate effect of these
particulate on the local air quality.
In addition to the climatological section
of the CDMG permit application, we would
prepare a permit application for submittal to
the Colorado Air Pollution Control Division
(CAPCD). Briefly, the permit application
would contain the following:
• process description to include site
drawings,
• expected hours of operation, e.g.,
continuously 365 days per yeaz, six days
per week, 20 hours per day,
be PM,o in coal dust from a breaker,
nitrogen oxides, or carbon monoxide
from generators or heating units.
Emission would be estimated from the
US EPA document AP-42, Compilation
of Air Pollutant Emission Factors,
Volume I: Stationary Point and Area
Sources, or manufacturer's specification,
• estimation of fugitive dust (PM,o)
emissions from extracting, conveying,
stockpiling, and transporting raw coal;
transporting waste coal to and deposition
at dump site; loading, conveying, and
transporting crushed coal oft-site; and
fugitive dust emissions from disturbed
land and haul roads. These emissions
would also be estimated using AP-42.
The time required to complete the permit
application would be 30 days. Upon
acceptance of the permit application by the
CAPCD, the permit approval process would
take a minimum of 135 days. However, the
process may take longer if permit backlogs
exist in the department at the time of
submittal. This permit application would be
submitted about the same time as the CDMG
permit application.
The process to permit a diesel-fueled
generator to provide power for the site will
depend on the size of the .generator.
According to the Environmental Protection
Agency document AP-42, Compilation of
Air Pollutant Emission Factors, Volume I:
Stationary Point Sources, potential emissions
from adiesel-fueled generator would be as
follows:
• estimation of emissions from stationary
point sources. Potential pollutants would
