Cement is stored in silos and mixed with aggregate and sand(both stockpiled on site),all of which is mixed with water inside a cement truck. The loadout and silos are controlled by a central dust collector. A second, bagfilter,which was previously used as a dedicated control for one of the silos is still in place,but it is no longer operating. To produce the septic tanks, cement is poured into 1,000-gallon, 1,200-gallon,or 1,500-gallon molds and allowed to cure for 28-30 days.The molds are removed and septic tanks are delivered and installed on site.Although septic tanks are still produced on site,most of Mr.Hildreth's business now is delivering concrete from his batch plant,which is operated on an"as needed"basis. IV. PERMITTED EXIISSION SOURCES: One Concrete batch plant with fabric filter air pollution control system(s)installed on all sources; 1. One(1)cement mixing weigh hopper and loading operation; and, 2. Silos for cement and flyash storage.

We discussed the following: a) Ms. Little verified the FACTFINDR information: no changes are needed. b) I viewed the maintenance logbook. Entries were up to date and listed maintenance performed. c) Mr.Hildreth stated that the facility had not run in several months and that all of their current production was coming out of the Rockingham facility. d) Production: Operating hours 0900-1700 Monday-Friday w/occasional Saturday Employees 7 including drivers Production(cu yd) 2018: 6,746 2017: 6,294.5 2016: 4,147 2015: 7,972.5 2014: 6,000 2013: 2,000 2012: 3,397 VI. INSPECTION SUMMARY: Due to the facility not operating we were limited to inspecting the areas around the plant and bagfilter for signs of excessive emissions. The batch plant is old however,we did not see any compromises in the ductwork or any indicators of excessive emissions. VU. APPLICABLE AIR QUALITY REGULATIONS: A. 15A NCAC 2D .0202—PERMIT RENEWAL AND EMISSION INVENTORY REQUIREMENT—The permittee shall submit an application for renewal of the facility's permit no later than 90 days prior to expiration, and shall include documentation of air pollutants emitted for the 2017 calendar year. APPEARED IN COMPLIANCE: The facility submitted their previous emissions inventory and permit renewal before the submittal deadline. The next deadline for submittal of emissions inventory and permit renewal is December 2025 for the 2024 calendar year. B. 15A NCAC 2D.0515—PARTICULATES FROM MISC.INDUSTRIAL PROCESSES— Particulate emissions shall not exceed allowable emission rates. APPEARED IN COMPLIANCE. Compliance was determined during the most recent permit review based on operating the source as described in the permit conditions. No changes have been made to operations since that determination. C. 15A NCAC 2D .0521—CONTROL OF VISIBLE EMISSIONS—Visible emissions shall not exceed 20%opacity. APPEARED IN COMPLIANCE. The facility was not operating during the inspection. We did not see any indication of issues with visible emissions at the time of inspection. D. 15A NCAC 2D .0535—NOTIFICATION REQUIREMENT—Notify DAQ in the event of excess emissions lasting longer than 4 hours resulting from malfunctions,breakdowns,or abnormal conditions. APPEARED IN COMPLIANCE. Mr. Hildreth stated that there had not been any operational exceedances that would have required notification to this office. E. 15A NCAC 2D .0540—PARTICULATES FROM FUGITIVE DUST EMISSION SOURCES— Fugitive dust emissions shall not contribute to substantive complaints,or excessive dust emissions beyond the property boundary. APPEARED IN COMPLIANCE. No fugitive dust concerns at the property boundaries were noted during the inspection. Ms. Little stated that they have not received any complaints related to dust. F. 15A NCAC 2D .0611—FABRIC FILTER REQUIREMENT—Particulate emissions controlled by fabric filters; annual internal inspections;record keeping. APPEARED EV COMPLIANCE. Mr.Hildreth performs the maintenance himself Mr.Hildreth stated that he removes the bags, inspects them for damage,rinses them, and lets them dry before reinstalling them. Records indicated that the last internal inspection of the bagfilter took place on 5 June 2018. G. 15A NCAC 2D .1104—TOXIC AIR POLLUTANT CONTROL REQUIREMENTS—Arsenic emissions shall not exceed the AAL. Concrete production limit based on distance to property boundary(340,500 cubic yards at 75 feet),which shall be marked. Monthly recordkeeping. Notification of changes. Annual reporting. APPEARED INCOMPLIANCE. The nearest property boundary is marked and has been verified at —75 feet which limits the facility to 340,500 cubic yards of production annually. Mr. Hildreth keeps a running log of concrete produced each day, and there is a spreadsheet available which shows the monthly and annual totals;the facility produced 6,746 cubic yards in 2018. The annual report was received late,on 25 March 2018,and a Notice of Violation was issued on 23 March 2018. H. 15A NCAC 2Q.0310—GENERAL PERMIT CRITERIA—The facility must meet the following criteria to qualify for a general permit: 1)No emissions sources operated other than those listed;2) facility not subject to regulations other than those covered by the general permit;3)facility is located in one of the listed counties;4)maximum hourly throughput does not exceed 138 cubic yards per hour;and 5)the facility does not exceed the maximum annual production rate based on distance to the property line(340,500 cubic yards at 75 feet). APPEARED INCOMPLIANCE. The facility appears to qualify for a general permit. No other emission sources other than those listed were noted,and the facility does not appear to be subject to any regulations, State or Federal,other than those listed in the general permit. The facility is located in Anson County,which is listed in the permit and covered by generalized modeling. The facility's maximum throughput is 100 cubic yards per hour,which is much less than the maximum permitted throughput,and the annual throughput, 6,746 cubic yards in 2018, is also much less than the 340,500 cubic yard limit.
