Introduction
On July 20, 2017, Charles Gerstell, NCDEQ Multimedia Inspector, contacted Mr. Dennis Shoaf of Shoaf Precast Septic Tank, Inc. for
an announced, targeted multimedia inspection. The facility was previously inspected by Mr. Davis Murphy on June 2, 2015 and found
to be operating in compliance with Air Quality rules and regulations at that time. The facility manufactures precast septic tanks and
junction boxes. The plant is open ten hours a day, five days a week but operates on a demand basis with some seasonal variability. Mr.
Shoaf confirmed that the IBEAM contact information was accurate.
Safety
It is recommended that inspectors wear safety shoes, safety glasses, hearing protection, and a hard hat.
Applicable Regulations
According to permit Condition A.1 the facility is subject to the following regulations: Title 15A North Carolina Administrative Code
(NCAC), Subchapter 2D .0202, 2D .0515, 2D .0521, 2D .0535, 2D .0540, 2D .0611, 2D .1806, 2Q .0309 and 2Q .07! I. 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.
Operating Status/Discussion
The facility is a precast concrete septic tank plant that receives cement, aggregate, sand, water, and admixtures and loads them into
trucks to be poured into molds and dried. The facility also manufactures junction boxes, catch basins, and other concrete fittings. None
of the permitted equipment was being operated during this inspection. According to Mr. Shoaf, the facility receives cement deliveries
about once per week.

The facility is permitted for two concrete plants. Plant No. I consists of a cement storage silo (ES-1) controlled by a bagfilter (CD-1).
Plant No. I is no longer at the site and has been removed. As noted in the previous inspection report, this plant was removed in 2012.
Mr. Shoaf explained that there are currently no plans to rebuild this plant. Plant No. 2 consists of a cement storage silo (ES-2), Fly ash
silo (ES-3), weigh hatcher (ES-4), and truck loadout operation. Each silo has a bagfilter (CD-2 & CD-3) located on top of each
respective silo to control emissions during loading. Cement is gravity fed into the weigh batcher directly below the cement storage
silo. Mr. Shoaf confirmed that the fly ash silo is no longer in use, and is currently empty. The fly ash silo is located next to the cement
silo, and when in use, it can auger feed to the weigh batcher. A small bagfilter on top of the weigh batcher controls emissions when
product is added to it. Material is gravity fed from the weigh batcher into the truck loadout, which is uncontrolled. Aggregate and sand
is conveyed from a storage bin to the truck loadout. Wet concrete is poured from the truck into molds that are allowed to dry for 24-48
hours before being stockpiled in the yard. The facility also has three concrete admixture tanks located in a shipping container (IES-1
through 3). The admixture tanks contain an accelerator, water reducer, and an air entrainer. Mr. Shoaf confirmed that there had been
no changes to facility equipment since the previous inspection.
Permit Conditions/Applicable Regulations
Condition A.2 contains the 15A NCAC 2Q .0304 and I SA NCAC 2D .0202 permit renewal and emissions inventory requirements.
The permit expires June 30, 2023 and the facility will be required to submit a renewal request and air pollution emission inventory
report for the 2022 calendar year 90 days prior to the expiration of the permit. The renewal process and emissions inventor were
discussed with Mr. Shoaf. Compliance with this condition is indicated.
Condition A.3 contains the 15A NCAC 2D .0515 particulate control requirement. This condition sets the maximum allowable
particulate emissions using the following two equations:
E — 4.10 * (P) °67 for P <= 30 tons/hr., or
E = 55 * (P) 01- 40 for P >30 tons/hr.
Where P is the process weight in tons/hour and E is the maximum allowable emissions rate for particulate matter in lbs./hour.
Bagfilter control efficiencies indicate that this condition will be met provided that the bagfilters are working properly. Also, the .
emission sources, baghouses, and associated ductwork appeared to be in good condition during this inspection. Compliance with this
condition is expected but could not be verified as the equipment was not operating at the time of inspection.
Condition A.4 contains the 15A NCAC 2D .0521 visible emissions control requirement. This facility is limited to a 20 percent
opacity limit when averaged over a six -minute period. Compliance with 213.0521 could not be verified as the facility equipment was
not in operation, but is expected if the bagfilters are functioning properly.
Condition A.5 contains the I SA 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. Shoaf stated that no such incidents since the previous inspection. Compliance with this condition is indicated.
Condition A.6 contains the 15A NCAC 2D .0540 fugitive dust control requirement. Mr. Shoaf indicated that the facility does not
typically have problems with dust and that they make sure their haul roads have plenty of gravel on them during dry periods. No
fugitive dust was observed traveling beyond the property boundaries at the time of inspection. No complaints regarding this facility
were found in the DAQ-IBEAM database. Compliance with this condition is indicated.
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 each bagfilter 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.
The bagfilter logbook was reviewed back to the last compliance inspection and found to be complete. According to the logbook,
internal inspections are typically performed every 4 months. Both CD-2 and CD-4 were last inspected on April 17, 2017. Mr. Shoaf
was reminded that if the facility decides to operate the fly ash silo (ES-3) in the future, inspection and maintenance requirements for
the associated bagfilter (CD-3) will be necessary. Compliance with this condition is indicated.

Condition A:8 contains the 15A NCAC 2D .1806 control and prohibition of odorous emissions requirements. No objectionable odors
were observed during this inspection. The facility does not have any previous odor complaints in the IBEAM database. Compliance
with this condition is indicated.
Condition A.10 contains the 15A NCAC 2Q .07t I Toxic Air Pollutant Emissions Limitation Requirement. The condition states, in
part, that the facility shall be operated and maintained in such a manner that emissions of any listed TAPS from the facility, including
fugitive emissions, will not exceed TPERs listed in 15A NCAC 2Q .0711. Calculations from permit review R06 demonstrate that the
facility will not exceed any TPERS when producing about 2800 cubic yards/year. Mr. Shoaf estimated that in CY 2015 and CY 2016,
this facility's production was approximately half of that rate. Compliance with 2Q .0711 is anticipated.
NSPS/NESHAP
Mr. Shoaf stated that the facility does not currently have any boilers, hot water heaters, or emergency generators on site. The facility
does not appear to be subject to any NSPS or NESHAP programs at this time.

(I)- EPA considers emissions from truck loading to be fugitive and silo bagfilters to be integral, rather than add on control
devices. Potential emissions for Title V applicability u oses are therefore listed in this column.
Permit Issues
There do not appear to be any permit issues at this time.
Source Tests
No source or VE tests have been conducted at this facility.
Compliance History
The facility has not been sent any Notices of Violation or Deficiency in the previous five years.
Conclusion
Based on review of records and visual observations, this facility appeared to be operating in compliance with Air Quality standards
and regulations at the time of this inspection.

Comment: , Material from truck washout area was observed deposited into a drainage ditch south of the site.
However, no deposits were observed within the culvert that leads under US Hwy 64 off of the
property. Mr. Shoaf explained that material was washed into the drainiage ditch as a result of
recent heavy rains. The excavated pits at the truck washout area had been recently cleaned out. _
Please ensure that all material deposited into the drainage ditch is removed to prevent it from
being washed off of the property. Measures should be provided beyond the excavated pits at the
truth washout area to prevent solids from being washed off site. This can include but not be
limited to, installation of rip rap and gravel check dams.

Dear Permittee:
Your facility is currently covered for stormwater discharge under General Permit NCG070000. This permit expires
on March 31, 2003. The Division staff is currently in the process of rewriting this permit and is scheduled to have
the permit reissued by early spring of 2003. Once the permit is reissued, your facility would be eligible for
continued coverage under the reissued permit.
In order to assure your continued coverage under the general permit, you must apply to the Division of Water
Quality (DWQ) for renewal of your permit coverage. To make this renewal process easier, we are informing you in
advance that your permit coverage will be expiring. Enclosed you will find a Permit Coverage Renewal
Application Form. The application must be completed and returned by October 2, 2002 in order to assure
continued coverage under the general permit. Due to staff and budget constraints, letters confirming our receipt of
the completed application will not be sent.
Failure to request renewal within the time period specified, may result in a civil assessment of at least $250.00.
Larger penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from your
facility without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1
and could result in assessments of civil penalties of up to $10,000 per day.
Please note that recent federal legislation has extended the "no exposure exclusion" to all operators of industrial
facilities in any of the 11 categories of "storm water discharges associated with industrial activity," (except
construction activities). If you feel your facility can certify a condition of "no exposure", i.e. the facility industrial
materials and operations are not exposed to stormwater, you can apply for the no ckposure exclusion. For additional
information contact the Central Office Stormwater Staff member listed below or check the Stormwater & General
Permits Unit Web Site at http://112o.enr.state.ne.us/su/stormwater.html
If the subject stormwater discharge to waters of the state has been terminated, please complete the enclosed
Rescission Request Form. Mailing instructions are listed on the bottom of the form. You will be notified when the
rescission process has been completed.
If you have any questions regarding the permit renewal procedures please contact Corey Basinger of the
Winston-Salem Regional Office at 336-771-4600 or Mack Wiggins of the Central Office Stormwater Unit at (919)
