Location:
This facility is located on East Hicks St.in Edenton. East Hicks is located behind the high school complex,which is
on South Broad St. (Hwy 17 Business). Turn off of South Broad St. onto East Freeman Street. Continue for
approximately 1/4 mile and the facility is located on the left. (They are currently using an entrance off East
Freemason Street and NOT the gate on East Hicks.)

Facility Summary:
This is a typical concrete batch plant. Sand,aggregate,cement,and flyash are weighed in a hopper and gravity fed
into a delivery truck.The cement and fly ash are stored in separate storage silos.The maximum through put capacity
is 72 cubic yards per hour.
Facility Safety:
Required PPE: Safety shoes,safety glasses,safety vest,and hard hats should be worn,especially if equipment is
operating.

Inspection Observations:
On 11/17/2021,I conducted a Compliance Assurance Visit(CAV)at Commercial Ready-Mix Concrete located in
Edenton,NC. I met with Mr.Jimmy McPherson,Plant Manager,and explained that I was there to perform an air
quality inspection. I examined the Environmental Notebook. It contained the bagfilter monthly inspections and
maintenance/repair records for the facility. All records were being kept up to date. Mr.McPherson stated that there
were no equipment changes made since the last inspection.
After reviewing the records,we toured the facility and identified the permitted sources. The facility was in
operation at the time of the inspection,the yard was watered,and the equipment appeared to be well maintained.No
dust,odor or visible emissions were observed at the time of the visit.
Regulatory Review:
2D.0515 Particulate From Miscellaneous Industrial Processes:
This standard requires that emission rates for particulate matter from any stack,vent,or outlet,resulting from any
industrial process for which no other emission control standard are applicable,shall not exceed the level calculated with
the equation E=4.10(P)0-"calculated to three significant figures for process rates less than or equal to 30 tons per hour.
For process rates greater than 30 tons per hour,the allowable emission rates for particulate matter shall not exceed the
level calculated with the equation E=55.0(P)0-11 -40 calculated to three significant figures. For the purpose of these
equations"E"equals the maximum allowable emission rate for particulate matter in pounds per hour and"P"equals the
process rate in tons per hour. With a process rate of 13.5 tons/hr.the allowable rate is calculated to be 23.4 lbs./hr.
Based on the DENR Emission Spreadsheet for Concrete Batching. The Actual Total PM is 2.764 lbs./hr. Compliance is
indicated.
2D.0521 Control of Visible Emissions:
Visible emissions from the permitted sources shall not be more than 20%opacity when averaged over a six-minute
period. I observed 2 truck loadings at the time of the inspection. The dust collector was operating,and I observed
no visible emissions. Compliance is indicated.
2D.0535 Excessive Emissions Reporting and Malfunctions:
There were no indications of equipment malfunctions that would result in excessive emissions requiring more than
four hours to repair. Compliance is indicated.
2D.0540 Particulates from Fugitive Non-Process Emissions Sources:
"Fugitive non-process dust emissions"means particulate matter that is not collected by a capture system and is
generated from areas such as pit areas,process areas,haul roads, stockpiles,and plant roads. At the time of the
inspection,I saw no evidence of any fugitive non-process dust emissions. Portable sprinklers were used to abate
dust on the material piles and on the road. Compliance is indicated.
2D.0611 Bagfilter Requirements:
Particulate matter emissions are controlled using bagfilters as described in the permitted equipment list.
Maintenance and inspections must be conducted in accordance with the manufacturer's recommendations and the
results must be documented in a logbook(written or electronic). Comprehensive monthly checks are being made on
the dust collector,each of which could be counted as an annual inspection. No deficiencies were noted.Magnehelic
gauge are kept between 2.5"-5"of water column. Compliance is indicated.
Compliance History(Five Years):
This facility has not received any SOCs,NOVs,deferrals or enforcement cases since the last inspection

Compliance Statement:
The facility appeared to be operating in compliance with all applicable Federal and State air quality rules and
regulations at the time of inspection.
