Federal regulatory program requirements (i.e. PSD, NANSR) must apply to this source at any such time that this source becomes major solely by virtue of a relaxation in any permit condition. Any relaxation that increases the potential to emit above the applicable Federal program threshold will require a full review of the source as though construction had not yet commenced on the source. The source must not exceed the Federal program threshold until a permit is granted. (Regulation Number 3, Parts C and D). GENERAL TERMS AND CONDITIONS 42. This permit and any attachments must be retained and made available for inspection upon request. The permit may be reissued to a new owner by the APCD as provided in AQCC Regulation Number 3, Part B, Section II.B. upon a request for transfer of ownership and the submittal of a revised APEN and the required fee. 43. If this permit specifically states that final authorization has been granted, then the remainder of this condition is not applicable. Otherwise, the issuance of this construction permit does not provide "final" authority for this activity or operation of this source. Final authorization of the permit must be secured from the APCD in writing in accordance with the provisions of 25-7- 114.5(12)(a) C.R.S. and AQCC Regulation Number 3, Part B, Section III.G. Final authorization cannot be granted until the operation or activity commences and has been verified by the APCD as conforming in all respects with the conditions of the permit. Once self-certification of all points has been reviewed and approved by the Division, it will provide written documentation of such final authorization. Details for obtaining final authorization to operate are located in the Requirements to Self-Certify for Final Authorization section of this permit.

The source used the gas to oil ratio of 5.51 scf/bbl,which is more conservative than the value estimated by the division bawd on the modelling provided. • Verified via COGCC'u wehsite:these wells are all on-site,so this source does meet the custody transfer exemption from NSPS Kb.There are 2-related facilities that appear to have well flow lines setup, however,none of these wells are producing.Additionally,according to COGCC's site,these related snes:(333000&305107)do not have separators. - ;= • This source uses the separator venting control device as a back-up(hence the 2 combustion devices)Because this is considered a back-up control device for the tanks/loadout,the pilot light emissions are only considered for the primary control (i.e.one combustion device)under the condensate tank and separators(Pont 008). this source is rem kestmg 9S`/,control efficiency,so will have additional parametric monitoring requirements outlined in the permit,including the establishment of breathing tank emissions such that in the event that the plot light is out arid there is not:liquid throughput,during this time,breathing emissions are considered and calculated as uncontrolled emissions The calculation methodology is -; outlined in the Notes to Permit Holder'and the breathing emissions are based on the ProVlar,simulation"Stream 5",from ihesimulation originally submitted with the application.

and existing facilities, including APEN updates. Incomplete APENs will be rejected and will require re-submittal. Your APEN will be rejected if it is filled out incorrectly, is missing information, or lacks payment for the filing fee. The re-submittal will require payment for a new filing fee. This APEN is to be used for tanks that store produced water associated with oil and gas industry operations. If your emission source does not fall into this category, there may be a more specific APEN available for your source(e.g. crude oil storage tanks, condensate storage tanks, hydrocarbon liquid loading, etc.). In addition, the General APEN (Form APCD-200)is available if the specialty APEN options will not satisfy your reporting needs. A list of all available APEN forms and associated addendum forms can be found on the Air Pollution Control Division (APCD) website at: www.colorado.gov/pacific/cdphetair-permits. This emission notice is valid for five(5)years. Submission of a revised APEN is required 30 days prior to expiration of the five-year term, or when a reportable change is made(significant emissions increase, increase production, new equipment, change in fuel type, etc.).

I have the following few items that I would like to follow-up on: • While I do understand that the methodology in PS Memo 09-02 does explicitly only present the methods to develop the flash portion of the emission factor, since the state emission factors do include flash, working, and breathing (per 3.2), site-specific emission factors are required to consider all sources of emissions. Often they are insignificant emissions, but they are required to be considered in the emissions calculations. If you would like to discuss this more, feel free to let me know. The PS Memo does not specify a method for determining working and breathing losses from a produced water tank based on samples that are required to be taken. As such Bonanza Creek requests the Division accept the emission factor until the PS Memo can be revised to require site specific emission factors to include working and breathing loses, and methods to do such. • Regarding the VRT&LP separator, if redlining the APEN and going with the more conservative estimate of emissions using the VRT emissions factors is your preferred path forward, we can absolutely do that. I will watch for an APEN addendum! I've attached a redlined APEN with supporting calcs and updated 102 Form. • Regarding the listing of wells, I now see how you have filled this out. Typically, if a source has more than 5 wells, they put"See addendum"on the APEN and list all of the wells on the addendum sheet. How this was submitted, though, is perfectly acceptable. o Regarding the off-location flowlines, does this facility process any materials from wells producing off-site? And if so, does any separation occur prior to reaching this facility? The newly reported wells were all built on the Wetco Farms A-4 pad and initial separation occurs at this facility. I think once I have this information, I will be able to finalize the analyses and draft permit! Thanks, again.

CDPHEGas Venting APEN - Form APCD-211 Air Pollutant Emission Notice (APEN) and CO 'f Application for Construction Permit All sections of this APEN and application must be completed for both new and existing facilities, including APEN updates. Incomplete APENs will be rejected and will require re-submittal. Your APEN will be rejected if it is filled out incorrectly, is missing information, or lacks payment for the filing fee. The re-submittal will require payment for a new filing fee. This APEN is to be used for gas venting only. Gas venting includes emissions from gas/liquid separators, well head casing, pneumatic pumps, blowdown events, among other events. If your emission unit does not fall into this category, there may be a more specific APEN for your source (e.g. amine sweetening unit, hydrocarbon liquid loading, condensate storage tanks, etc.). In addition, the General APEN (Form APCD-200) is available if the specialty APEN options will not satisfy your reporting needs. A list of all available APEN forms can be found on the • Air Pollution Control Division (APCD)website at: www.colorado,gov/cdphe/apcd. This emission notice is valid for five (5)years. Submission of a revised APEN is required 30 days prior to expiration of the five-year term, or when a reportable change is made (significant emissions increase, increase production, new equipment, change in fuel type, etc.). See Regulation No. 3, Part A, II.C. for revised APEN requirements.

Incomplete APENs will be rejected and will require re-submittal. Your APEN will be rejected if it is filled out incorrectly, is missing information, or lacks payment for the filing fee. The re-submittal will require payment for a new filing fee. This APEN is to be used for gas venting only. Gas venting includes emissions from gas/liquid separators, well head casing, pneumatic pumps, blowdown events, among other events. If your emission unit does not fall into this category, there may be a more specific APEN for your source (e.g. amine sweetening unit, hydrocarbon liquid loading, condensate storage tanks, etc.). In addition, the General APEN (Form APCD-200) is available if the specialty APEN options will not satisfy your reporting needs. A List of all available APEN forms can be found on the Air Pollution Control Division (APCD)website at: www.colorado.gov/cdphe/aped. This emission notice is valid for five (5)years. Submission of a revised APEN is required 30 days prior to expiration of the five-year term, or when a reportable change is made (significant emissions increase, increase production, new equipment, change in fuel type, etc.).
