Section 12 — Regulatory Review
Regulation 1 - Particulate, Smoke, Carbon Monoxide and Sulfur Dioxide
005
Section II.A.1 - Except as provided in paragraphs 2 through 6 below, no owner or operator
of a source shall allow or cause the emission into the atmosphere of.any air pollutant which
is in excess of 20% opacity. This standard is based on 24 consecutive opacity readings
taken at 15 -second intervals for six minutes. The approved reference test method for
visible emissions measurement is EPA Method 9 (40 CFR, Part 60, Appendix A (July,
1992)) in all subsections of Section II. A and B of this regulation.
Section II.A.5 - Smokeless Flare or Flares for the Combustion of Waste Gases No owner
or operator of a smokeless flare or other flare for the combustion of waste gases shall
allow or cause emissions into the atmosphere of any air pollutant which is in excess of
30% opacity for a period or periods aggregating more than six minutes in any sixty
consecutive minutes.
Regulation 2 — Odor '
005
Section LA - No person, wherever located, shall cause or allow the emission of odorous air
contaminants from any single source such as to result in detectable odors which are
measured in excess of the following limits: For areas used predominantly for residential or
commercial purposes it is a violation if odors are detected after the odorous air has been
diluted with seven (7) or more volumes of odor free air.

Regulation 3 - APENs, Construction Permits, Operating Permits, PSD
005
Part A-APEN Requirements
Criteria Pollutants: For criteria pollutants, Air Pollutant Emission Notices are required for:
each individual emission point in an attainment area with uncontrolled actual emissions of
two tons per year or more of any individual criteria pollutant (pollutants are not summed) for
which the area is in attainment.
(Applicant is required to file an APEN since emissions exceed 2 tons per year VOC)
005
Part B -- Construction Permit Exemptions
Applicant is required to obtain a permit since uncontrolled VOC emissions from this
facility are greater than the 5.0 TPY threshold (Reg. 3, Part B, Section 11.D.3.a)
005
Part B, III. D.2 - RACT requirements for new or modified minor sources located in ozone
non -attainment areas
This source is not subject to this requirement because it is located in an ozone attainment
area.
Regulation 8 — Hazardous Air Pollutants
005

This source is not subject to MACT HH because it is not located at a major source of HAP.

Separator controlled by a flare
According to the operator, the flare is only used when produced gas from the well is diverted from the
gathering pipeline during downtime and maintenance.
Emissions were calculated using VOC wt fraction.
(scf/lhr) * (Ib/Ib-mol) * (% fraction from sales gas analysis) / (379.4 scf/lb-mol) = lb/hr * (hr/yr) / 2000 lb/T) =
TPY
VOC = (102 TPY * 2000 lb/T) / (6.3 MMscf/yr) = 32380.95 lb/MMscf
NOx and CO (from AP -42: NOx = 0.068 lb/MMBtu; CO = 0.370 lb/MMBtu)
Benzene = (1086.9 Ib/yr) / 6.3 MMscf/yr = 172.5 lb/MMscf
Toluene = (1032.4 Ib/yr) / 6.3 MMscf/yr = 163.9 lb/MMscf
Ethylbenzene = (171.2 Ib/yr) / 6.3 MMscf/yr = 27.2 lb/MMscf
Xylenes= (365.3 Ib/yr) / 6.3 MMscf/yr = 57.98 lb/MMscf
n -Hexane = (6744.4 Ib/yr) / 6.3 MMscf/yr = 1070.5 lb/MMscf
2,2,4-TMP = (3.8 Ib/yr) / 6.3 MMscf/yr = 0.6 lb/MMscf
A permit will be issued because uncontrolled VOC emissions are greater than 5 TPY (permit threshold).
This emergency flare is a simple, non -manufactured flare; therefore, Manufacturer, Model, and Serial
numbers are not applicable.
An extended gas analysis was performed on gas sample(s) obtained from Dietzler 10-14-9-60 on June
21, 2012. Therefore, an extended gas analysis is not part of the initial testing requirements for this
source. A site -specific gas analysis is, however, required on an annual basis. Since the source is a True
Minor source of HAPs (and not anywhere close to the Synthetic Minor threshold), HAP tracking is not
required. Therefore, an extended gas analysis, includes HAP speciation, is not required.
Facility Wide Comments
On 1/15/2013, I was told by Ashley Campsie of CH2M Hill, the consultant for this project, that Patricia
Moden has replaced Kimberly Long as the contact person for this project. I was told that Kimberly Long is
no longer with Carrizo.

Air Pollution Control Division (APCD) on grounds set forth in the Colorado Air Quality
Control Act and regulations of the Air Quality Control Commission (AQCC), including
failure to meet any express term or condition of the permit. If the Division denies a
permit, conditions imposed upon a permit are contested by the applicant, or the Division
