No equipment was installed, and there did not appear to be any electricity on-site. The facility appeared to be not constructed and this inspector performed a targeted inspection previously on July 17,2020 and confirmed that the facility had not started 2 construction. The facility was issued a new permit on January 3, 2018. According to permit review RO1 (Ms. Taylor Hartsfield, former WSRO-DAQ employee, now RRO Regional Supervisor for DAQ), on January 3, 2018, "Carolina Sunrock LLC - Prospect Hill Facility will be a drum mix, HMA plant capable of processing 250 tons per hour and a truck mix, concrete batch plant capable of processing 120 cubic yards per hour." This should be verified upon full operation. A calculation of the modeling coordinates was done at the site on August 7, 2018. "Although the exact location of the equipment is not known,the location pin was taken at the centermost point." Emissions Point ID UTM Coordinates Center Point 36.256100,-79.170400 Safety Equipment: Safety shoes, safety glasses,hard hat, safety vest,and hearing protection are most likely required PPE equipment when inspecting this facility, but this should be verified once the plant becomes operational.

This facility is not subject to RMP requirements of the 112(r) program since it does not use or store any of the regulated chemicals in quantities above the threshold levels in the rule.The facility is only subject to the General Duty requirements contained in the General Duty Clause. Discussion: The facility appeared to be not operating as of April 13, 2021. The facility is or will be located at 4266 Wrenn Road, Prospect Hill,North Carolina, was not constructed, and there was no evidence of any activity at the plant. The facility appears to be complying due mainly because of no equipment being operated or fully constructed. Permit Conditions/Applicable Regulations: Condition A.2 contains 15A NCAC 2D .0202 permit renewal and emissions inventory requirements. The facility was issued a new permit on January 3,2018. The permit expires on August 31, 2025, and the facility is required to submit a renewal request and air pollution emission inventory report for the 2024 calendar year 90 days prior to the expiration of the permit. Compliance is expected at this time. Condition A.3 pertains to the 15A NCAC 2D .0503 "Particulates from Fuel Burning Indirect Heat Exchangers" requirement. The condition applies to the two-natural gas/No. 2 fuel oil-fired liquid asphalt cement heaters(ES-HI and ES-H2). The cement heaters will have a combined heat input of less than 10 MM/Btu/hr and are limited to 0.6 lbs/MMBtu. According to the permit review R00,the anticipated particulate matter emissions are equal to 0.0075 and 0.024 lbs/MMBtu when combusting natural gas and No. 2 fuel oil, respectively. Compliance is expected. Condition A.4 contains the 15A NCAC 2D .0506 "Particulates from Fuel Hot Mix Asphalt Plants"requirement. The propane/natural gas/No. 2 fuel oil/recycled No. 2 fuel oil/recycled No. 4 fuel oil-fired drum dryer/mixer(ES-HMA1) is subject to this regulation. Tile plant must limit particulate emissions according to the following equations: E=4.9445 (P)0.4111 for P<300 tons per hour E=60 lbs/hr for P>300 tons per hour 3 The expected actual emission rate(8.25 lbs PM/hr) is below the allowable limit(55.4 lbs PM/hr). Compliance can be expected. Condition A.5 contains the 15A NCAC 2D .0510 "Particulates from Sand, Gravel, or Crushed Stone Operations" requirement. The facility must take measures to minimize particulate matter from becoming airborne to prevent exceedances of the ambient air quality standards for particulates. Fugitive dust must be controlled as referenced in 2D .0540 and other emissions from crushed stone operations are applicable under 2D .0521. Compliance is expected. No evidence of dust nor any complaints have been received, even though plant is not built. Condition A.6 contains the 15A NCAC 2D .0515 particulate control requirement. This condition sets the maximum allowable particulate emissions using the following equations: E=4.10(P)067 when P<_30 tons/hour E=55.0(P)"-40 when P> 30 tons/hour The rule applies to all the concrete batch sources. As referenced in permit review R00 by Taylor Hartsfield on September 21,2017, expected actual emission rates are from the NCDEQ Concrete Batch Plant spreadsheet submitted with the application. As the expected actual rates are below the allowable rates,compliance is expected.

Condition A.15 contains the 15A NCAC 2D .1100 "Control of Toxics Air Pollutants"requirement. The hot mix asphalt (HMA)facility has modeled for arsenic unlisted compounds(ASC-other), benzene, formaldehyde, mercury vapor, and nickel metals since the expected actual emissions are above the respective toxic emission rates. The affected sources are the drum dryerhnixer, storage silos, truck loadouts, liquid asphalt heaters, and batch plant. The final/revised modeling analysis(for formaldehyde only) memorandum by Nancy Jones,DAQ Meteorologist for Air Quality Analysis Branch (AQAB), was issued on September 14,2017. The following was borrowed from Ms. Jones,as part of the analysis. "AERMOD (16216r)using five years(2011-2015)of meteorological surface data from Burlington and upper air data from Greensboro was used to evaluate impacts in elevated terrain. Source locations and release parameters are attached. Direction-specific building dimensions,determined using EPA's BPIP-Prime program, were used as input to the model for building wake effect determination. Receptors were placed around the facility's property line at 25-meter intervals. Receptors were spaced at 100 meter intervals out to 2,000 meters from the property line."The following table illustrates the results of the modeling analysis. 5 Max�amam Aye��gxng AAL ' AAL; Eimssion(s)Sours` TAP(CAS#) Emissons Rates Concentration o od [µgdm�� Peri g/rn � (/o] ....___........_....._..._...._..__........._._._...............__.....,....::..............................._............:.:.....�.:..........:...:......:,.............:_�.... ........._:.::_....._.:°..._......:._....................... ........._.......__..........................._(..._.._......._.:_..............._._..............._..._.___....._..., ......_._.._....._........._........_..L..._....__....._.......
