[R307-401-8] Engineer Review N130710005: Sunroc Corporation- Henry Gypsum Processing Plant March 26, 2025 Page 8 PERMIT HISTORY When issued, the approval order shall supersede (if a modification) or will be based on the following documents: Supersedes AO DAQE-AN0130710004-09 dated September 9, 2009 Is Derived From NOI dated October 4, 2024 Incorporates Additional Information dated January 23, 2025 Incorporates Additional Information dated March 6, 2025 REVIEWER COMMENTS 1. Comment regarding 10-Year Review: This is a 10-year review to Approval Order (AO) DAQE-AN0130710004-09, dated September 9, 2009. The source contact information, permit formatting, and state and federal rule applicability have been reviewed and updated. The source has not made any changes to equipment or emissions. The engine construction date was added to the approved equipment list. The various mobile sources were removed from the equipment list as the DAQ permits stationary sources, and mobile sources are not stationary sources. The following language of condition II.B.4.a.1 was removed: “Six points, distributed along the length of the haul road or in the operational area, shall be chosen by the Executive Secretary or the Executive Secretary's representative. An opacity reading shall be made at each point when a vehicle passes the selected points. The accumulated six readings shall be averaged for the compliance value.” Ultra-low sulfur diesel (ULSD) conditions were added to the AO as MACT Subpart ZZZZ applies to the source and MACT Subpart ZZZZ requires the use of ULSD. The previous AO did not include emissions estimates for PM2.5, HAPs, or CO2e. Estimates have been included as part of this 10-year review. Since the diesel engine emissions and conditions are based off of fuel consumption rather than operational hours, a fuel consumption rate is estimated. Various diesel engine manufacturers estimate that a 600 hp engine consumes roughly 32 gallons of diesel fuel per hour assuming full load. A 600 hp engine consumes roughly 24 gals/hour at 3/4 load. It is conservatively estimated that an engine will operate 3,500 hours per year based on diesel fuel consumption rates. PM2.5 emissions are conservatively estimated to be equal to PM10 emissions. HAP and CO2e emissions are estimated using AP-42 Section 3.3 (Gasoline And Diesel Industrial Engines) assuming the 600 hp engine operates for 3,500 hours per year. In the emission summary table, PM2.5 emissions are estimated to be 6.1 tons per year (TPY), HAP emissions are estimated to be 0.1 TPY, and CO2e emissions are estimated to be 1,220 TPY. Condition II.B.4.d in the previous AO DAQE-AN0130710004-09, stated "The owner/operator shall comply with all applicable requirements of R307-309 for Fugitive Emission and Fugitive Dust source." R307-309 applies to all new or existing sources of fugitive dust one-quarter acre or greater and any sources of fugitive emissions located in PM10 or PM2.5 nonattainment or maintenance plan areas as defined in 40 CFR 81.345 (July 1, 2011). The source is located in an attainment area and there are no applicable requirements in the rule. Since no requirements of the rule are applicable to the source, this condition has been removed from the AO. The source is still required to comply with a fugitive dust control plan outlined in UAC Rule R307-309-6 or other plan acceptable to the Director. [Last updated April 24, 2025] Engineer Review N130710005: Sunroc Corporation- Henry Gypsum Processing Plant March 26, 2025 Page 9 2. Comment regarding Federal Subpart Applicability: NSPS 40 CFR 60 Subpart OOO (Standards of Performance for Nonmetallic Mineral Processing Plants) applies to select equipment at nonmetallic mineral processing plants that commenced construction, modification, or reconstruction after August 31, 1983. The screens, crushers, and transfer/drop points (conveyors, stackers, feed bins) at this facility are subject to NSPS Subpart OOO. 40 CFR 60 Subpart IIII (Standards of Performance for Stationary Compression Ignition Internal Combustion Engines (CI ICE)) applies to owners and operators of stationary CI ICE that commenced construction after July 11, 2005, where the stationary CI ICE are manufactured are manufactured after April 1, 2006. The diesel engine at this facility was constructed prior to this date; therefore, NSPS Subpart IIII does not apply to the source. MACT 40 CFR 63 Subpart ZZZZ (National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines) applies to owners and operators of stationary internal combustion engines (RICE) at an area source of HAP emissions. The facility operates RICE and is an area source of HAP emissions; therefore, MACT Subpart ZZZZ applies to this facility. [Last updated March 25, 2025] 3. Comment regarding Title V Applicability: Title V of the 1990 Clean Air Act (Title V) applies to the following: 1. Any major source 2. Any source subject to a standard, limitation, or other requirement under Section 111 of the Act, Standards of Performance for New Stationary Sources; 3. Any source subject to a standard or other requirement under Section 112 of the Act, Hazardous Air Pollutants. 4. Any Title IV affected source. This facility is not a major source and is not a Title IV source. This facility is subject to 40 CFR 60 (NSPS Subpart OOO) regulations. Therefore, Title V applies to this facility as an area source.
