The facility was previously inspected by Mr. Stephen Helms, former Environmental Specialist of DAQ-WSRO on June 10, 2015 and reported that the facility appeared to be operating in compliance with applicable Air Quality standards and regulations at that time. All IBEAM contacts were confirmed to be accurate. Safety Equipment: Site -specific personal protective equipment includes safety shoes, safety glasses, hard hat and reflective vest. Hearing protection is needed near any operating equipment. Wheel chocks are required when leaving any vehicle unattended on -site. Visitors are required to attend a 10-minute safety orientation prior to entering the mine area. Applicable Regulations: Applicable regulations listed in the air permit include Title 15A NCAC, Subchapter 2D .0202, 2D .0501, 2D .0510, 2D .0521, 2D .0524 (40 CFR 60, Subpart OOO), 2D .0535, 21) .0540, 2D .1806, 2Q .0102 and 2Q .0309. This facility is not required to implement a risk management plan (RMP) in accordance with federal regulation 40 CFR 68, Section 112(r), because they do not purchase, produce, use or store any of the regulated chemicals in quantities above their corresponding threshold limits. However, the facility is subject to the General Duty clause contained in this rule. Discussion: The facility mines and crushes granite and slate for the construction materials industry. It typically operates Monday through Friday, 50 hours/week, for approximately 52weeks/year. The facility was not in operation at the time of the inspection to al low for repairs. However, product was being loaded for customers. 2 The facility operates two exempt, aboveground, 10,000-gallon diesel fuel storage tanks, 1-1 and 1-2, that dispense fuel to the water truck, haul trucks and bucket loaders. The facility also operates an exempt, aboveground, 3,000-gallon gasoline storage tank, I-3. The facility owns portable, crushing, conveying, and screening equipment for this facility. None of the equipment was in operation at the time of inspection to allow for repairs. The facility lists several exempt sources which include; two above -ground 10,000-gallon storage tanks (1-1 & 1-2), one 3,000- gallon gasoline storage tank (1-3) and gasoline dispensing process (I-4). All were observed during the inspection. Specific Permit Conditions: Condition A.2 contains 15A NCAC 2D .0202 permit renewal and emissions inventory requirements. The permit expires April 30, 2024 and the facility is required to submit a renewal request and emission inventory report for the 2023 calendar year 90- days prior to the expiration of the permit. This condition was discussed with Mr. Nivens and Mr. King and compliance with this condition is anticipated. Condition A.3 contains the 2D .0501(c) equipment reporting requirements. The permittee shall maintain a complete equipment list and flow diagram of all permitted equipment operating on the site, including identification numbers, dates of manufacture, dimensions, process rated capacities and performance testing information. The facility is allowed to install new, or replace existing, non -primary crushing equipment without obtaining a permit modification as long as it does not change the primary crushing rated capacity of the facility, and as long as they provide written notification to the Division that includes a revised equipment list and flow diagram. Since the previous inspection, the facility had placed the "36" X 143' Conv. TC 140 AggStack Radial Stacker" (ID No. 939) into service. All documentation relating to startup and testing of the subject equipment had been submitted to the Division. During the inspection, Mr. Nivens provided the inspector with a current equipment list and flow diagram, demonstrating compliance. Condition A.4 contains the requirements for 2D .0510 particulate control requirements for particles from sand, gravel, or crushed stone operations. This condition requires the facility to take steps to reduce, to a minimum, any particulate matter from becoming airborne to prevent exceeding the ambient air quality standards beyond the property line. This facility makes use of wet suppression in order to control process particulate matter. A water truck is also used to control fugitive dust from roads inside the facility. Compliance with this condition is anticipated. Condition A.5 contains the primary crusher specifications. This condition requires the facility to submit a permit application if any changes are made to the primary crusher other than like -far -like replacement. It also requires the facility to submit a permit application in the event the primary crusher is replaced by a dissimilar crusher. The primary crusher is a jaw crusher rated at 475 tons per hour at a 9-inch maximum crusher setting. Mr. King confirmed that the crusher was not set over a 4-inch crusher setting at a rate of approximately 350 — 375-tons per hour. Compliance with this condition is anticipated. Condition A.6 contains the 15A NCAC 2D .0521 visible emissions control requirement. This facility is limited to 20%opacity visible emissions, for sources manufactured after July 1, 1971, when averaged over a six -minute period. According to the equipment list observed at the time of inspection, all equipment with the exception of the 4 1 /4' Cone Crusher (ID No. 12) and the Diester Screen #3 (ID No. 14) were manufactured after July 1, 1971. Since the facility was not operating, compliance could not be determined. Condition A.7 contains the 15A NCAC 2D .0521 visible emissions control requirement. This facility is limited to 40% opacity visible emissions, for sources manufactured as of July 1, 1971, when averaged over a six -minute period. According the equipment list observed at the time of inspection, only the 4 114' Cone Crusher (ID No. 12) and the Diester Screen #3 (ID No. 14) were manufactured prior to July 1, 1971. Since the facility was not operating, compliance could not be determined. Condition A.8 Condition A.8 (213.0524, 40 CFR 60 Subpart 000) concerns "New Source Performance Standards." The facility is required to submit construction and startup notifications for crushers, screens and conveyors, and conduct performance testing to determine visible emissions on affected sources. Visible emissions from affected sources are limited to 15% opacity for crushers, 10% opacity for conveyors and screens and 0% opacity for conveyors and screens that process saturated materials. A test protocol and an advanced notice of the test date are also required. A provision of this condition exempts the replacement equipment from testing if it is of equal or lesser production capacity than the existing source. For affected facilities that commenced construction, modification or reconstruction on or after April 22, 2008, visible emissions are further restricted to 12%opacity for crushers and 7%opacity for conveyors and screens. As previously noted, the most recent installation of subject equipment occurred in 2016 with the installation of the "36" X 143' Conv, TC 140 AggStack Radial Stacker" (ID No. 39). Records indicate that the facility fulfilled the notification, testing and reporting requirements, demonstrating compliance at that time. The facility is also required to perform monthly, periodic inspection to check that the water is flowing to discharge nozzles on wet suppression systems that were constructed on or after April 22, 2008. The facility must record each inspection including the date and corrective action taken in a logbook that can be made available to DAQ personnel upon request. Monthly inspections on the subject equipment was verified, and the last inspection occurred on July 21, 2016. Compliance is indicated. Condition A.9 contains the 15A NCAC 2D .0535 rules which requires the permittee to notify the director of any excess emissions lasting longer than four hours resulting from a malfunction, breakdown of process or control equipment or any other abnormal conditions. Mr. King and Mr. Nivens knew of no excess emissions lasting more than four hours since the previous inspection and there were no issues registered to this facility in IBEAM indicating likely compliance. Condition A.10 contains the 15A NCAC 2D .0540 fugitive dust control requirement. During the inspection, the water truck was operating and appeared to effectively minimize fugitive dust emissions from operations of the loaders and haul trucks. The inspector observed no fugitive dust emissions migrating beyond the facility's boundary during the inspection nor have any complaints been received indicating likely compliance. concerns the control of fugitive dust emissions. The facility operates a 40-ton water truck which was operating during the inspection. The inspector observed no fugitive dust emissions near the property boundary and no complaints have been received, indicating likely compliance. Condition A.11 contains the requirements for 2D .1806 control and prohibition of odorous emissions. The inspector detected no objectionable odors at any time during the inspection and the facility does not have any previous odor complaints in [BEAM. Compliance with this condition is indicated. Condition A.12 (40 CFR 63, Subpart CCCCCC) concerns the control of hazardous air pollutant (HAP) emissions from gasoline dispensing facilities. The facility operates an exempt, aboveground, 3,000-gallon gasoline storage tank, I-3, that is subject to this rule. Section 63.1 t 116 of this rule contains the work practices and recordkeeping requirements for facilities with a gasoline throughput less than 10,000 gallons per month. Within 24 hours of a request from this Division, the facility must make records available that document their gasoline throughput. Mr. Nivens provided the inspector with records showing the facility purchased 1,012.5gallons of gasoline for the 2015 calendar year, indicating likely compliance. MACT/GACT Applicability: As previously discussed, the facility is subject to NESHAP Subpart CCCCCC.
