I really appreciate it! Please proceed with the redlines to the condensate tanks APEN to match the calculations provided. After the redlines have been made, can I get a copy of the APEN? I have attached an updated O&M plan for the condensate tanks and loadout as well as an updated 102 Form.As far as I know,the two Cummins engines (points-002 and -006, respectively)are no longer on site. Upon confirmation of that, I will submit cancellation requests for each engine.As for the Doosan 21.9L, I believe it was included in that 1/24/2019 package that contained the other GP02s. I have attached a copy of the APEN for reference. Finally, please see below for PDC's comments on draft permits 19WE1020 and 19WE1021. Permit 19WE1020 Permit Condition 1: Requirement to Submit a Notice of Startup—As this is an existing source that was previously permitted under a GP01, can this condition be removed?

I have attached draft permits for you to review. Please note that these are being issued to SRC Energy, Inc as that is who the application came in from. While I understand that the Transfer of Ownership is in process, upon speaking with Paul Rusher, he recommended this path forward. Can you provide any feedback on these draft permits by Thursday, June 18, prior to these permits going to public notice? Can you please provide updated O&M plans for the loadout and condensate tanks? Since this application was submitted,we have published updated O&M plans to reflect the requirements due to the ozone nonattainment redesignation. Also, can you provide an updated Form APCD-102? I do see that there was a GP02 requested and processed for a PSI 8.1L engine; however, according to the facility inventory form submitted, it looks like there are 3 other engines that should be permitted. I am aware of 2-GP02 permits that were received 1/24/2019 and have not yet been processed (Doosan 11.1L&Caterpillar G3406TA)- I am following up on their status as I know there were some administrative errors,.but I think we may still be missing an engine (Doosan 21.9L). Do you have records as to when an APEN was submitted for that point?We do have an AIRS Point 002 that has a GP02 for a Cummins 225 HP engine and a GP06 under point 004 for a Cummins 363 diesel engine, which do not appear to have been cancelled.Are those still active/on-site?

Please let me know if you have additional questions or need anything else from me as you continue your review. • For the condensate storage tanks and the condensate loadout,this source has requested 98%control. Would you like to proceed with this application requesting 98%control?As I had mentioned to Brad/Chad,this will lead to increased sampling, monitoring, and testing requirements. Please proceed with 98% control on the condensate storage tanks. As far as the condensate loadout control goes, it looks to me like 95%was requested on the APEN, but I might be missing something. Either way, PDC would prefer to only claim 95%control for condensate loadout as it is controlled by a separate combustor. o If you would like to request 98%control for these sources, can you please provide make/model/serial numbers for all combustors used to control these 2 sources?All four combustors are IES (make) 96" (model). The serial numbers are:01-07, 01-08,01-35, and 01-36. • In the original applications, it appears that the volume of vapors combusted for the condensate storage tanks had considered an additional 20% buffer in terms of calculating combustion emissions,according to my emailing with Chad Powell.This is not a standard practice for construction permits,as the source requests their PTE for condensate throughput and the https://mai I.google.com/mail/u/0?i k=44f88835c3&view=pt&sea rch=all&permmsg id=msg-f%3A1 6 706 00868 2 67704 92 5&simpl=msg-f%3A1670600868... 5/20 7/14/2020 State.co.us Executive Branch Mail-FW:[EXTERNAL]:Fwd:SRC Energy-SRC Wiedeman Pad-Permitting Requests emissions should be based on that value. Would you like to maintain the original request or modify the combustion emissions?This one took some time for me to wrap my head around. I came to the same conclusion as you seemed to initially, in that the ProMax run included yields a throughput of about 1,585,785 bbls/yr. After reviewing previous submittals for this facility, it would appear the included ProMax run was for the GP01 update made in January of 2019 for this site. I'm assuming SRC/LT included it with this package purely as reference to use the previously approved emission factors. Using that ProMax run, I calculate a GOR of 20.686 scf/bbl. Using that same GOR with the actual and requested throughputs from this submittal, I calculate the emissions shown below(pilot emissions included).These seem to match the values you originally suggested to Chad/Brad, but I would just like to confirm that's the case and that we arrived at those values in a similar manner. o Actuals:2.57 TPY NOx& 11.73 TPY CO o Requested:3.08 TPY NOx& 14.06 TPY CO • The original combustion emissions did not consider the VOC emissions from the pilot light combustion.We have begun including these calculations within our analysis and also our permitted limits for sources controlled by combustion devices. Can you please submit VOC combustion emission calculations?We typically see sources use the emissions factors from AP-42,Chapter 1, Table 1.4-2. Please see the attached pilot light calc sheet.The fuel usage and heat content used were those from last October's submittal. These values, in conjunction with the EFs from Table 1.4- 2,yield a small enough value that when rounded to the hundredth (as is done in the calc sheet)they appear to be zero. When the decimal is carried out a little further, however,the value is 1.34 x 10^-3 TPY VOC for the tank combustors and 3.36 x 10^-4 TPY VOC for the loadout combustor.

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 condensate 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, produced water 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. 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.

The average daily production rate from those first thirty(30)days is then multiplied by 365 to achieve an annualized production value. This annualized production value then has the default decline factor of 60%'applied to forecast the first 12 months of production from those new wells. Production for existing wells is forecasted using a daily average that is annualized based on the most current data available. Production while controls operational represents a portion of this facility's production where the tank emissions were uncontrolled. 1-Decline Factor of 60%-PS Memo 05-01"Oil B Gas Condensate Tank Batteries Regulatory Definitions and Permitting Guidance" NOx and CO emission factors were taken from Table 4 of the Texas Natural Resource Conservation Commission's(TNRCC)"Air Permit Technical Guidance for Chemical Sources- Flares and Vapor Oxidizers"document(shown as'TCEQ'on any associated APENs). The waste gas stream is assumed to be high-Btu(>1,000 Btu/scf). Site Specific Emission Factors have been used to calculate emissions.
