Colorado Department of Public Health and Environment
Air Pollution Control Division
Colowyo Coal Company, L. P.
Permit No. 95MF1040
Issuance 7
See Attachment A for information on emission factors and methods used to calculate limits.
Details of operations included under AIRS ID numbers are described in the Attachment A
Note: Compliance with the fugitive emission limits shall be demonstrated by not exceeding the
production limits listed below and by following the attached particulate emissions control
plan.
Compliance with the annual limits shall be determined by recording the facility's annual emissions
for the pollutants listed in the table above on a rolling twelve (12) month total. By the end of each
month a new twelve-month total shall be calculated based on the previous twelve months' data.
The permit holder shall calculate monthly emissions and keep a compliance record on site, or at a
local field office with site responsibility, for Division review.
The total facility activities resulting in emissions of fugitive particulate matter (also referred as
process emissions) shall be limited by the emission limits specked in Condition No. 2, and all
other activities, operational rates and numbers of equipment as stated in the application.
Throughputs indicated on Attachment A are not limits, but given to indicate the level of activities
at the overall process rate limits specified under Condition No. 4. Records of the actual activities
and emissions of criteria (fugitive particulate matter, particulate matter less than 10 pm [PM,o],
particulate matter less than 2.5 pm) pollutants shall be maintained by the applicant and made
available to the Division for inspection upon request. Such records shall, at the minimum, contain
the details given in Attachment A.
Note: Compliance with the fugitive emission limits shall be demonstrated by not exceeding the
production limits for AIRS IDs 001, 025, 029 and 031listed below in Condition 4 and by
following the attached particulate emissions control plan.
Compliance with the point source emission limits for AIRS IDs 022, 023, 024 and 028 shall be
demonstrated by calculating emissions on a daily, monthly, and rolling 12 month basis.
Compliance with both the daily and annual point source criteria pollutant emission limits shall be
based on multiplying the actual production as defined in Condition 4, the emission factors and
applying the control efficiency values for each AIRS ID as defined in Attachment A. Annual actual
limits shall be recorded in a rolling twelve month total format.
Throughputs indicated on Attachment A are given to indicate the level of activities at the overall
process rate limits specified under Condition Number 4. Records of the actual activities and
emissions of criteria (fugitive particulate matter [PM], particulate matter less than 10pm [PM10],
particulate matter less than 2.5pm [PM2.5], Oxides of Nitrogen [NOx] , Carbon Monoxide [CO],
and Oxides of Sulfur [SO2]) pollutants shall be maintained by the applicant and made available to
the Division for inspection upon request. Such records shall, at the minimum, contain the details
given in Attachment A.
3. The particulate emission control measures listed on Attachment B (as proposed in the Air
Pollutant Emission Notice(s) / Particulate Emission Control Plan submitted to the Division) shall
be applied to the particulate emission producing sources as required by Regulation No. 1.
PROCESS LIMITATIONS AND RECORDS
4. This source shall be limited to the following maximum consumption, processing and/or
operational rates as listed below. Daily, Monthly and Annual records of the actual process rate
