An inventory of each insignificant activity and associated emission calculations must be made available to the Division for inspection upon request. For the purposes of this condition, insignificant activities are defined as any activity or equipment, which emits any amount but does not require an Air Pollution Emission Notice (APEN) or is permit exempt. (Reference: Regulation Number 3, Part C. II.E.) Total emissions from the facility, including all permitted emissions and potential to emit from all insignificant activities, must be less than: • 100 tons per year of V0C • 10 tons per year of acetaldehyde (HAP) • 25 tons per year of total hazardous air pollutants (HAP). 3.

These limits may be revised upon request of the permittee providing there is no exceedence of any specific emission control regulation or any ambient air quality standard. A revised air pollutant emission notice (APEN) and application form must be submitted with a request for a permit revision. (Reference: Regulation Number 3, Part B II.A.4.) 2) This source is subject to the Common Provisions Regulation Part.II, Subpart E, Affirmative Defense Provision for Excess Emissions During Malfunctions. The permittee must notify the Division of any malfunction condition which causes a violation of any emission limit or limits stated in this permit as soon as,possible, but no later than noon of the next working day, followed by written notice to the Division addressing all of the criteria set forth in Part II.E.1. of the Common Provisions Regulation. See: https://www.colorado.gov/pacific/cdphe/aqcc- regs. 3) The following emissions of non-criteria reportable air pollutants are estimated based upon the process limits as indicated in this permit. This information is listed to inform the operator of the Division's analysis of the specific compounds emitted if the source(s) operate at the permitted limitations.

Any challenge to or appeal of a condition hereof must constitute a rejection of the entire permit and upon such occurrence, this permit must be deemed denied ab initio. This permit may be revoked at any time prior to self-certification and final authorization by the Division on grounds set forth'in the Colorado Air Pollution'Prevention and Control Act and regulations of the 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 revokes a permit, the applicant or owner or operator of a source may request a hearing before the AQCC for review of the Division's action. (Reference: Regulation Number 3, Part B III.F.) 11) Section 25-7-114.7(2)(a), C.R.S. requires that alt sources required to file an Air Pollutant Emission Notice (APEN) must pay an annual emission fee. If a source or activity is to be discontinued, the owner must notify the Division in writing requesting a cancellation of the permit. Upon notification, annual fee billing will terminate.

Update permit format to current version. This modification was also intended to remove the limit on hours for receiving truck traffic for deliveries or shipments. However,the dispersion modeling did not successfully demonstrate compliance for particulates due to the high back ground levels. It was finally agreed that the permitting would be split into two parts with the particulate modeling demonstration delayed until later. Thus this modification continues to restrict the hours for truck traffic on the plant site.

As such the source originally claimed only Tanks T61, T 62 and T 64 as storage tanks. However, in the intervening time they have determined that they might ship 200 proof ethanol on occasion and so now ttank 65 is also a storage tank . The remaining tanks are considered process tanks or have a capacity which exempts them from Kb requirements . Thus the tanks subject to Kb are T61 — capacity 500 , 000 gallons , used to store denatured ethanol T62 — capacity 500 , 000 gallons , used to store denatured ethanol T64 — capacity 100, 000 gallons , used to store denaturant (gasoline) T65 - capacity 100 , 000 gallons used to store ethanol (200 proof) These tanks are also subject to Regulation Number 7 VI . b. 2 . The tanks are subject to Reg 7 because the denatured ethanol contain gasoline and Reg 7 requirements apply to petroleum tanks . These tanks are not subject to Kb T63 — capacity 100 , 000 gallons used as a process ethanol tank ( 190 proof) T66 — capacity below Kb requirements ( 1 , 460 gallons) used to store "Corrosion Inhibitor" However, the Regulation Number 7 VI . b. 2 do not apply to tanks T 63 and T 66 since they are process tanks and do not contain a petroleum product) . Instead , the Division determined that the requirements apply to the tanks as Reasonably Available Control Technology ( RACT) . Subpart VV — applies to plants where construction , reconstruction or modification began prior 11 /7/2006 . The addition of the ethanol recovery device ( ERD) dces not seem to fit the definition of the modification as listed in NSPS 60. 2 where a modification must also lead to an increase in air pollutants emitted either of an existing pollutant or the addition of a new pollutant. The ERD recovers additional ethanol thus causing a decrease in emissions . If it is determined otherwise that this activity is a modification to the existing plant, then subpart VVa would apply instead . Scrubber efficiency and stack testing results Stack testing for AIRS points 004 and 005 (scrubbers) gave control values in excess of 99% reduction for VOC emissions . FRE proposed a limit of 95 tons of VOCs for all point sources and also placed a restriction on rail loading to further limit the potential emissions from loadout. Subtracting out VOC emissions from AIRS points 002 , 003, 009 , 010, 012 and 013 results in the remaining emissions attributed to the scrubbers (79 . 2 tons per year. ) Back calculating a scrubber control efficiency based on this new VOC emission limit gives the following Uncontrolled total emissions (AIRS 004 and 005) = 3404 tpy Proposed controlled limit for combined scrubbers = 79. 2 tpy Scrubber efficiency calculation = 100 * (( 1 - (79 . 2/3403)) = 97 . 67 rounded up to 97 . 7 (changes from previous value of 97 . 5%) . Note that stack testing at FRE has demonstrated scrubber efficiency at 99%+ , thus claiming a lower value is acceptable.

AIR POLLUTION CONTROL DIVISION PRELIMINARY ANALYSIS SUMMARY PERMIT NUMBER: 04WE1423 DATE: September 4, 2019 APPLICANT: Front Range Energy, LLC REVIEW ENGINEER: Michael J. Harris, P.E. CONTROL ENGINEER: R. K. Hancock, III, P.E. PROJECT DESCRIPTION Front Range Energy, LLC is proposing to increase emission limits for the existing ethanol fuel production plant. This plant is located at 31375 Great Western Drive, Windsor, CO. ESTIMATED EMISSIONS The resulting estimated controlled emissions from permit 04WE1423 are listed below. Annual Emissions in tons: PM PM10 PM2.5 NOx SO2 VOC CO Current 18.69 17.69 63.67 -- 65.25 53.57 Emissions New Emissions 8.2 6.7 5.8 63.7 0.5 95.0 59.4 (Point Source) New Emissions 7.5 2.0 0.9 14.0 (Fugitive) Source Classification This source is considered a synthetic minor source for VOC emissions for Non Attainment New Source Review (NANSR) and Title V Operating permit applicability. Emissions of VOCs could exceed 100 tons per year if Front Range Energy LLC. did not install and operate air pollution control equipment. The source has requested an increase in the VOC emission limit of more than 25 tons per year and public comment is required by Regulation 3, Part B.III.C.1.a. The company has made an application for issuance of a federally enforceable permit. The Division has determined that the proposed source will comply with all applicable regulations and standards of the Colorado Air Quality Control Commission and has made a preliminary determination of approval of the application Colorado Department of Public Health and Environment Page 1 of 5 Air Pollution Control Division - GRAIN ELEVATORS AND FEED MILLS - Air Pollutant Emission Notice(APEN) —and—Application for Construction Permit O New Facility O Transfer of Ownership' O Change in Throughputs O APEN Update O Change in Equipment El Request a Modification to Existing Permit All sections of this APEN and application must be completed for both new and existing facilities,including APEN updates.

The maximum theoretical potential for receiving, storing,and handling is 750 tons per hour,which equates to unloading a 25 ton truck every 4 minutes in each pit,or unloading a 100 ton railcar every 8 minutes.
