40 for P >30 tonslhr Compliance is expected since the bagfilters appear to be properly maintained and in good working order Condition A 4 contains the 15A NCAC 2D 0521 visible emissions control requirement This facility is limited to 20% opacity visible emissions when averaged over a six -minute period No visible emissions were detected from the bagfilter devices during this inspection Compliance with this requirement is indicated Condition A 5 contains the 15A NCAC 2D 0535 rule which requires the permittee to notify the director of any excess emissions lasting longer than four hours resulting from a malfunction, a breakdown of process or control equipment or any other abnormal conditions Mr Hepler and Mr Rathbone stated that no malfunctions had occurred since the last inspection and there are no issues registered to this facility in the (BEAM database indicating compliance with 0535 Condition A 6 contains the 15A NCAC 2D 0540 fugitive dust control requirement Majority of the site is surfaced with concrete Facility staff stated that aggregate and work areas are wetted with water when needed to control dust on site According to the DAQ ]BEAM database, no complaints have been received regarding fugitive dust emissions at this facility and minimal fugitive dust was observed during this inspection, with none leaving the boundary of this facility Compliance with 2D 0540 is expected Condition A 7 contains the 15A NCAC 2D 0611 fabric filter inspection, maintenance, and recordkeeping requirements for particulate matter emissions control The facility is required to perform, at a minimum, an annual (for each 12-month period following the initial inspection) internal inspection of the fabric filter system and perform periodic inspection and maintenance as recommended by the equipment manufacturer The facility is required to record the results of all inspection and maintenance activities in a logbook Mr Hepler presented bagfilter maintenance and production records to this inspector These records indicated the facility performs routine inspections on a weekly basis and internal inspections on a monthly basis The most recent internal inspection was performed on August 5, 2016, while the most recent routine inspection was performed on August 16, 2016 Compliance with this condition is expected Condition A 9 contains the 15A NCAC 2D 1806 control and prohibition of odorous emissions requirements No objectionable odors were observed originating from the facility at the time of inspection The facility does not have any previous odor complaints in IBEAM database Compliance with this condition is expected NSPS/NESHAP This facility does not appear to be subject to any NSPS or NESHAP rules at this time Facility Wide Emissions Actual emissions from permit review R08 for Ready Mixed Concrete Co — High Point (Read Plott, November 10, 2013) o Pollutant L Actual Emissions tual, Uncontrolled Emissions (tp F P I{ : g 8 },.. �„ ��,�€ t (y) _ a.-.4 §k..�.., ..� t ' S.Idi—f PM 030 5 7 PM10 014 22 SO2 5 6 106 _ --- -
