Fluctuations in emissions that occur when the separator dumps into the tank are reasonably foreseeable. (iii) The permittee shall monitor and document the proper operation of the control device. Time intervals between monitoring shall not exceed 14 days. Indications of improper operation for a flare include, but are not limited to, absence of pilot light, malfunction of electronic ignition, and/or presence of smoke.

On May 23, 2011 Jake, who is also working on some EOG sites, e - mailed David Long about the flare calculations. The mole fraction VOC had been used instead of mass fraction VOC. This caused the emissions to be underestimated and with the correct calculations facility status could change.

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.

State -Developed Emission factors in lb/1000 gal are: County Produced Water Tank Default Emission Factors (lb/1000 gal) VOC Benzene n -Hexane Adams, Arapahoe, Boulder, Broomfield, Denver, Douglas, Jefferson, Larimer and Weld 6.2381 0.1667 0.5238 The APEN states that the tanks contain less than 1% by volume crude oil on an annual average basis which qualifies the source for the categorical exemption (Regulation 3, Part B, Section II.D.1.m). However, this source will be permitted because if it was not controlled, the overall permitted VOC emissions would be greater than 100 TPY and become a major facility. The operator has requested synthetic minor status and accepted Federally enforceable controls, so this point will be included to ensure synthetic minor eligibility. AIRS Point 002 Crude Oil Tanks These tanks contain oil with an API gravity less than 40 degrees. EOG used E&P Tank to estimate the flash emissions off this tank battery. From E&P Tank- uncontrolled ton/year= 9.7 TPY VOC VOC=(9.7 TPY)*(20001b/ton)/(146,000bbl/yr)= 0.133 lb/bbl VOC or 3.1671b/1000 gallons Page 9 AIRS Point 003 Emergency Tank Gas going to the flare would be routed to this tank in case of a flare outage. The gas is vented to atmosphere from this tank. The APEN was submitted with worse -case scenario calculations. This consists of 3 upset conditions in a 12 month period. Each instance of upset conditions was estimated to be 12 hours in length.

EOG will continue to flare gas until a pipeline is available. Emissions were calculated using VOC wt fraction. (scf/hr) * (Ib/Ib-mol) * (% fraction from sales gas analysis) / (379.4 scf/lb-mol) = lb/hr * (hr/yr) / 2000 lb/T) = TPY Emission factors for NOx, CO, and PM10 came from AP -42, table 13.5-1 Emission factor for SOx also came from AP -42 and is based on 100% conversion of sulfur to SO2 at 2000 grains/MMscf VOC E.F. = (1,534.6 TPY * 2000 lb/T) / (91.25 mmscf/yr) = 33,635 Ib/MMscf HAP's Emission. Factors: Benzene = (6844.5 Ib/yr) / 91.25 MMscf/yr= 75 lb/MMscf Toluene = (5168.1 Ib/yr) / 91.25 MMscf/yr = 56.6 Ib/MMscf Ethylbenzene= (86839 Ib/yr) / 91.25 MMscf/yr= 9.52 lb/MMscf Xylenes= (2146.6 Ib/yr) / 91.25 MMscf/yr = 23.5 lb/MMscf n -hexane = (41959.6 lb/yr) / 91.25 MMscf/yr = 459.8 = —460 Ib/MMscf Page 10 AIRS Point 005 Truck Loadout of Crude Oil and Produced Water AP -42: Chapter 5.2 Equation 1 L = 12.46*S*P*M/T L = loading losses in lb per 1000 gallons loaded S = Saturation Factor P = true vapor pressure of liquid loaded [psia] M = molecular weight of vapors [lb/lb-mole] T = temperature of bulk liquid loaded [deg.

When reviewing calculations for a similar facility in non -attainment, another engineer working on these sites noticed the fugitive emissions were calculated incorrectly. These errors triggered fugitives in attainment facilities to be permit -required (increase from 1.5 TPY to 2.4 TPY). EOG submitted APENS for the fugitive emissions on 2/14/12. Points 001-006: No monthly limits will be put in the permit even though this is a synthetic minor source. After discussing this source with Chris Laplante 3-8-2011 it was decided that since production at an E&P site is not steady enough to impose those kinds of limits. Compliance on a monthly limit may not be possible, while a yearly limit could be.
