PERMIT APPLICATIONS
There are not any permit applications in process by DAQ-RCO for this facility at the time of this inspection.
SOURCE TEST
At the time of the inspection,the facility was testing both hospital,medical and infectious waste incinerators(MvIIWI)(ES01 and
ES02).Both incinerators were being tested for particulate matter(PM),visible emissions(VE),hydrogen chloride(HCl),and metals
using EPA Methods 5,9,26A, and 29 respectively. Specifically,the facility was testing for the metals lead(Pb),cadmium(Cd),and
mercury(Hg).
Both incinerators are subject to 15A NCAC 2D .1206"Hospital, Medical and Infectious Waste Incinerators,"which incorporates parts
of 40 CFR Part 60, Subparts Ce and Ec by reference.Both units are also subject to 15A NCAC 2D.1100"Control of Toxic Air
Pollutants"and 40 CFR Part 62 Subpart HHH"Federal Plan Requirements for Hospital/Medical/Infectious Incinerators Constructed
on or Before June 20, 1996."The limit for VE is 6%opacity on a 6-minute block average.The limits for PM and HCl are 25
milligrams per dry standard cubic meter(mg/dscm)and 6.6 parts per million by volume(ppmv),respectively.The limits for Pb,Cd,
and Hg are 0.036,0.0092,and 0.018 mg/dscm,respectively.
The test was performed by Derek Brewster,Tyler Mills,Brad Ourts,and Joe Thompson,of TRC Environmental Corporation based
out of Raleigh,NC.The Protocol Submittal Form was received by this office on February 20,2018.The protocol was approved by the
DAQ-SSCB on March 16,2018.The test consisted of at least three 2-hour runs on each incinerator unit with all EPA Methods
performed concurrently.Methods 5 and 29 were done on the same test train.The meter box used for Methods 5/29 had the ID No.
M10,was calibrated on December 21;2017,by T.Mills,and had OH= 1.756 and Y=0.9883.The meter box used for Method 26A
had the ID No.Ml8,was calibrated on December 13,2017,by T.Mills,and had OH= 1.950 and y=0.9853.
ESO1 and ES02 were operating with charge rates of 1,706.8 and 1,519.2 lbs/hr,respectively on April 10.The other operating
parameters at the time of source test are summarized below under Condition 2.LA.2.n.There were not any detectable visible
emissions throughout the testing period other than an attached steam plume on both incinerator stacks.The weather was cloudy in the
morning,but clear in the afternoon,temperature ranged from 50-70°F with a 2-mph wind from S.According to TRC's on-site results
of the Method 9 tests performed on both units,all readings were 0%.Preliminary results indicate compliance with the opacity limits.
The results will be due by May 11,2018.
DISCUSSION
The facility has two dual chamber hospital,medical and infectious waste incinerators(HMIWI)(ESO1 and ES02)firing natural gas,
each with a 4.6 million Btu/hr primary chamber bumer and a 6.0 million Btu/hr secondary chamber bumer.Each incinerator is
controlled by a selective non-catalytic reduction(SNCR)system,a packed bed scrubber,a venturi scrubber equipped with mist
eliminator,and a sulfur impregnated carbon bed,all installed in series.These control devices are installed to control emissions of PM,
CO,NOx,dioxins/furans,and other HAP/TAPs.During the inspection,both incinerators and their respective control devices were
operating.There were no visible emissions observed other than steam plumes from the incinerator stacks.These stacks were observed
from the roof.The operating parameters at the time of inspection are summarized below under Condition 2.1.A.2.n.
A basic description of the operation of a HMIWI at this facility is as follows:A hopper is loaded with boxes of HMIW,which
represents a charge.The hopper is tipped into an open pre-incineration chamber,and,after closing,a hydraulic ram pushes the charge
into the primary combustion chamber.From there,the charge is combusted as it moves down the primary chamber,aided by other
rams and underfire air.At the end of the primary chamber,the ash and non-combusted material is quenched with water and an auger
transfers the ash to a waste bin.This bin then goes to a landfill as the waste no longer has its original hazardous properties.
Back in the incinerator,the combustion gases from the primary chamber travel up to a secondary chamber.A secondary burner
destroys any combustible content of the primary combustion gases and reduces CO emissions.The exhaust then enters the SNCR
system where ammonia or urea is injected in order to reduce NOx formation.Afterwards,the gases enter a packed bed scrubber and
associated quench column.The packed bed scrubber has a caustic solution to reduce acid gas emissions.The quencher reduces
temperature which reduces dioxin/furan emissions.After quenching,the gases pass into the venturi scrubber to reduce PM emissions.
Following the venturi scrubber,the gases go through a mist eliminator to remove some of the steam plume.The last step is for the
exhaust to pass through the sulfur impregnated carbon bed to reduce mercury emissions.
Page 3 of 13

Associated with the two HMIWIs are two exempt cooling towers(1-CT-1 and 1-CT-2)each with a 55,200 gallons per hour water
recirculation rate.The cooling towers assist the quencher in reducing the temperature of the exhaust.These cooling towers were in
operation during the inspection with small amounts of steam emissions visible from the roof of the facility.
The facility also has a diesel-fired emergency generator(EG1).It was not in operation during the inspection.The generator is a 500
kW Caterpillar model DCPXL that was installed in July 2013.The non-resettable hours meter was recently replaced on September 23,
2016,and read 56.6 hours during the inspection.Before being replaced,the old hour meter read 164.2 hours.A certification sticker for
NSPS purposes is located on the engine,and was observed by this inspector.The generator uses ultra-low sulfur diesel(ULSD)fuel
from Alamance Oil.Carolina CAT services the engine semi-annually.The engine is tested twice per week for about 20 minutes.
During an emergency loss of power,the engine is equipped to start automatically to provide power to the incinerators and prevent
opening of the bypass stacks,which would occur seven seconds after the incinerators lose power.

Condition 2.1.A.Lb states that to comply with the above limits,the charge rates into the incinerators shall not exceed 1,870.0 pounds
per hour for ESO1 and 1,870.0 pounds per hour for ES02.In addition,each incinerator's stack height shall be a minimum of 82.4 feet
above ground level.Also,the maximum carbon bed inlet temperatures shall not exceed 168XF for CD05 (for ESO1)and 164.1°F for
Page 4 of 13

CD06 (for ES02).During the inspection,the 3-hour average charge rates of ESO1 and ES02 read 1,706.8 and 1,519.2 pounds per hour,
respectively,on the data acquisition system(DAS)utilized by the facility. The stacks appeared to remain at the appropriate height,and
there was no evidence that they had been adjusted.The 3-hour average maximum carbon bed inlet temperatures for CD05 and CD06
were 154.3°F and 153.4°F,respectively.The facility appears to be in compliance.
Condition 2.1.A.Le states that in order to minimize bypass event duration and emissions,the facility shall do the following:
A. Install an uninterruptible power supply (UPS) for the control system to eliminate any "reboot" time associated with the
programmable logic controllers(PLCs).The UPS shall be equipped with a readiness indicator;
B. Install a power outage indicator as an input to the PLCs;
automatic re-closure of the bypass stack within 5 minutes after a power failure;
C. Revise the PLC logic to require a yp p ,
D. Install a low-level switch on the emergency generator diesel tank;
E. Install a pressure switch to the water supply to alert operators to a loss of water supply;
F. Operate devices to assure continuous removal of the ash from the primary chamber;and
G. Reduce combustion air to the primary chamber by alternately shutting the fan off and on in 1 minute cycles to achieve a net
reduction in airflow of 50%during the bypass event.
According to Mr. Skrzypczak,the applicable devices(A-E)have been installed/revised,and the operational changes(F-G)have been
implemented.Therefore,the facility appears to be in compliance.
Condition 2.1.A.Ld states that the facility shall not incinerate dental waste,as defined in the waste management plan required by
Section 2.1.A.2.bb.During the inspection,it was verified that the facility is not incinerating any dental waste.Any dental waste
received is set aside and trucked out for incineration elsewhere.If any dental waste containers are accidentally placed on the
conveyors to the incinerators,the scanners before the loading mechanism would alert the facility of the problem and stop the process.
The facility appears to be in compliance.
Conditions 2.1.A.Le and f state that the facility shall comply with the testing requirements in Section 2.LA.2 j. for cadmium and
mercury.The testing shall also be performed in accordance with General Condition JJ.As previously mentioned,the facility was
testing both units for cadmium and mercury during the inspection.The facility appears to be in compliance.
Condition 2.1.A.1.g states that the facility shall conduct the monitoring,maintenance,and inspections for each incinerator and each
control device,as required by Sections 2.1.A.2.u.through aa. See this section below for a detailed discussion.The facility appears to
be in compliance.
Conditions 2.1.A.l.h and i states that the facility shall maintain records or any other process operational information as is necessary
to determine compliance with 15A NCAC 2D.1100.In addition,the facility shall keep records of inspections and maintenance on the r .
control devices as required by Section 2.1.A.2.ff.See this section below for a detailed discussion.The facility appears to be in
compliance.
Condition 2.1.A.l.i states that for each stack test,the facility shall track and record details for the waste being burned and the material
that may be carried over into the stack test period.Tracking shall include,at a minimum,a cross-reference of the identity of the waste
generator with the company's customer list(the identity information shall include the nature of the business activity),the type of
business waste,the total weight of each container,and the time the material entered the incinerator.This information will be
summarized and submitted as part of the stack test report.Mr. Skrzypczak assured that this information would be provided with the
stack test report for the test being conducted at the time of the inspection.The facility appears to be in compliance.
Condition 2.1.A.l.k states that the reporting requirements of 15A NCAC 2D .1206(see Sections 2.1.A.21h.and ii.)shall be
considered sufficient for reporting compliance with 15A NCAC 2D .1100.See this section below for a detailed discussion.The
facility appears to be in compliance.
Conditions 2.1.A.2.a and b states the emissions limitations for both HMIWI units(ESO1 and ES02)as stipulated by Table 1B of 40
CFR Part 60,Subpart Ce.The facility conducted source testing on the units from April 28-May 1,2015.The results of that test were
approved by the DAQ-SSCB per the memo issued on June 22,2016.The facility was conducting repeat(every 3 years)testing during
this inspection on both units.The results will be due by May 11,2018.

The facility shall also comply with the calculated emission limits listed in Section 2.1.A.La.of this permit for the following
pollutants: arsenic and its compounds,beryllium and its compounds,cadmium and its compounds,and chromium(VI)and its
compounds.The emission limits apply at all times.The facility appears to be in compliance.
Condition 2.1.A.2.e states that the test methods and procedures described in 15A NCAC 02D.2600,40 CFR Part 60 Appendix A,and
40 CFR Part 61 Appendix B shall be used to determine compliance with emission limits.All testing shall be conducted according to
the provisions of General Condition JJ.When determining compliance with emission limits for metals,Method 29 of 40 CFR Part 60
shall be used,except that SW 846 Method 0061 shall be used for chromium(VI). [Note:Currently,this condition wrongly states that
Method 29 shall be used for sampling chromium(VI).]As mentioned,the facility was performing testing on both units for cadmium,
lead,and mercury during this inspection.The facility was using Method 29,and therefore,appears to be in compliance.
Conditions 2.1.A.2.d through g state that the facility shall conduct an initial performance test in order to determine compliance with
the emission limits in Section 2.1 A.2.a,and to establish maximum and minimum values for the following operating parameters for
each control device,as applicable:maximum charge rate;maximum flue gas/carbon bed inlet temperature;minimum secondary
chamber temperature;minimum pressure drop across the venturi scrubbers,or minimum amperage to wet scrubber;minimum venturi
scrubber liquor flow rate;minimum packed bed scrubber liquor pH;and minimum SNCR reagent flowrate.The facility may conduct
repeat performance tests at any time in order to establish new operating parameters.Upon receipt of an approved test that
demonstrates different operating parameters,the facility shall attach the approval memo containing the revised operating parameters to
this permit and maintain the parameters in the associated ranges contained therein.The facility may conduct a repeat performance test
within 30 days of violation of applicable operating parameter(s)to demonstrate that the affected facility is not in violation of the
applicable emissions limit(s).Repeat performance tests conducted pursuant to this paragraph shall be conducted using the identical
operating parameters that indicated a violation.Although the facility was stack testing both units during the inspection,the facility has
not established any new operating parameters since the issuance of this permit.Therefore,the operating parameters summarized under
Section 2.1.A.2.n still apply.The facility appears to be in compliance.
Conditions 2.1.A.2.h through k state the requirements and frequency for emissions testing.The facility shall conduct annual
performance tests for the opacity limit,and meet the requirements of 40 CFR 60.56c(b).For compliance with the PM and HCl
emissions limits,the facility shall start by testing annually.If three tests over a three-year period indicate compliance,then the facility
Page 6 of 13

may test for PM and HCl once every three years(no more than 36 months from previous test).Annual tests shall be resumed if a test
results in non-compliance.For compliance with the mercury, cadmium,and lead emission limits,the facility shall test once every
three years(no more than 36 months from previous test).For each metals test,the facility shall track and record details for the waste
being burned and the material that may be carried over into the stack test period.Tracking shall include,at a minimum: a cross-
reference of the identity of the waste generator with the company's customer list(the identity information shall include the nature of
the business activity);the type of business waste;the total weight of each container;and the time the material entered the incinerator.
This information will be summarized and submitted as part of the stack test report.The use of the bypass stack during a performance
test shall invalidate the performance test.During the inspection,the facility was testing both units for opacity,PM,HCI,Cd,Hg,and
Pb.The facility is currently on a 3-year cycle for testing both units,except that opacity testing is annual.The waste tracking records
from the test performed during this inspection will be submitted with the results of the test due by May 11,2018.There was no use of
the bypass stack during this performance test.The facility appears to be in compliance.
Conditions 2.1.A.2.1 and m state the types of materials allowed to be incinerated.The facility shall only incinerate waste that meets
one of the following requirements:hospital waste or medical/infectious waste,as defined by 40 CFR Part 60, Subpart Ec and 15A
NCAC 02D.1202;international garbage(USDA/APHIS);confidential documents generated in the health care industry; controlled
substances captured by law enforcement agencies;non-hazardous trace chemotherapeutic waste materials;or non-hazardous
pharmaceuticals.Dental waste,as defined in the DAQ approved waste management plan(See 2.1.A.2.bb),is not to be incinerated.
During the inspection,most of the labels on the waste boxes indicated that they were received from hospitals,health clinics,and
medical labs.None of the boxes were opened for verification,but it's presumed that the labeling is accurate.As mentioned under
section 2.1.A.l.d,the facility does not incinerate any dental waste.The facility appears to be in compliance.
Condition 2.1.A.2.n states that the facility shall ensure that all operating parameters remain within the acceptable range as measured
on a 3-hour rolling average,following the date on which the maximum and minimum operating parameters are established.Operation
outside of acceptable ranges shall constitute a violation of established operating parameter(s),except that operating parameter limits
do not apply during performance tests or during periods of startup and shutdown when no waste is being charged.The following table
summarizes the most current operating parameters and those observed during the inspection.During the inspection,Mr. Skrzypczak
stated that the facility has an electronic control system with interlocks that prevents charging of the units if the operating parameters

Conditions 2.1.A.2.p through r state the requirements and frequency for parameter monitoring.The facility shall install,calibrate(to
the manufacturer's specifications),maintain,and operate the following monitoring devices:
• Devices for monitoring the maximum and minimum parameters,listed in Section 2.LA.2.n.such that these devices measure
and record values for those parameters at the frequencies listed in Table 3 to 40 CFR Part 60 Subpart Ec.
• A device or method for measuring the use of the bypass stacks,including date,time,and duration.
• A continuous temperature monitoring and recording system for temperature in the primary chamber of each affected HMIWI.
• A device to continuously measure the reagent flowrate to the SNCR and record the data at least once per minute.
• A continuous monitor for both oxygen and CO in order to determine proper operation of each HMIWI.
The facility shall obtain monitoring data at all times during HMIWI operation except during periods of monitoring equipment
malfunction,calibration,or repair.At a minimum,valid monitoring data shall be obtained for 75%of the operating hours per day for
90%of the operating days per calendar quarter that the affected facility is combusting HMIW.All monitoring devices and associated
equipment used to show compliance with emission limits shall be subject to a Quality Assurance(QA)program which must include
procedures and frequency of the following:calibrations;standards traceability;operational checks;maintenance;auditing;data
validation;and a schedule for implementing the QA program.The QA program must be submitted to and approved by the DAQ-
WSRO Regional Supervisor.As previously mentioned,the facility has a DAS for monitoring all required operating parameters and
use of the bypass stack.According to the semi-annual report received January 29,2018,for ESO 1 and ES02,the facility had 3.00 and
57.83 hours of inoperative monitor data,which represents 0.08 and 1.65%of the total operating time in CY2017,respectively.As this
is less than what is allowed,the facility appears to be in compliance.
Condition 2.1.A.2.s states that to assure compliance with the visible emissions limit,the facility shall observe the emission points of
each HMIWI for any visible emissions above normal once a day.The daily observation must be made for each day of the calendar
year period to ensure compliance with this requirement.The facility shall be allowed three days of absent observations per semi-
annual period.The observations must be maintained in a log on-site and include the dates,times,results,and any corrective actions.
During the inspection,the daily visible emissions observations log sheets for CY2017 were spot checked.The facility keeps an annual
calendar sheet and crosses off each day after the VE observation has been filed.All the days for CY2017,except December 25,2017
(closed/shutdown for Christmas),were crossed off on the calendar.There were no visible emissions observed during the inspection
other than steam plumes.The facility appears to be in compliance.
Condition 2.1.A.2.t states that the facility shall install a carbon monoxide continuous emissions monitoring system(CO CEMS)on
the exhaust stack of each incinerator.The CO CEMS shall be used to determine compliance with the CO emission limit using a 12-
hour block average.The CO CEMS shall be operated in accordance with the applicable procedures under appendices B and F of 40
CFR Part 60.When demonstrating compliance with the CO emission limit,the Permittee may substitute a CO CEMS for the annual
CO performance test and minimum secondary chamber temperature.Excess CO emission reports as measured by the CEM systems
must be submitted semi-annually.During the inspection,the CO CEMs were operating and the 3-hour averages for ESO 1 and ES02
were 1.39 and 1.04 ppmv,respectively,which is less than the 11 ppmv limit.According to the semi-annual CEM report received
January 25,2018,ESO1 and ES02 had no instances of excess CO emissions.The CEM report was accepted by the DAQ-SSCB on
January 31,2018.The facility appears to be in compliance.
Conditions 2.1.A.2.0 through w state that the facility shall perform an annual inspection of each HMIWI.The inspection shall,at a
minimum,meet the requirements of 40 CFR 60.36e(a)(1)(i)through(xvii).Also,the facility shall perform an annual inspection of
each control device associated with each HMIWI.At a minimum,each control device must meet the following criteria(if applicable):
ensure proper calibration of thermocouples,sorbent feed systems,and any other monitoring equipment;and generally observe that the
equipment is maintained in good operating condition.Any necessary repairs found during an inspection of a HMIWI or control device
shall be completed within 10 operating days of the inspection unless the owner or operator submits a written request to the Director for
an extension of the 10 operating day period.According to the facility's records,ESO 1 and all associated controls were annually
inspected on May 31,2017,and ES02 and all associated controls were annually inspected on June 16,2017.During these shut downs,
the facility thoroughly inspects the incinerators and performs any required annual maintenance on the packed bed(CDO 1 and CD02)
Page 8 of 13

and venturi(CD03 and CD04)scrubbers.All maintenance was performed in a timely manner.Further discussion about the carbon
beds(CD05 and CD06)is in the following section.The last routine shut downs of ESO1 and ES02 occurred on March 11,2018 and
April 2-3,2018,respectively.The facility appears to be in compliance.
Conditions 2.1.A.2.x through as state the carbon bed requirements.The carbon beds(CD05 and CD06),used for the control of
mercury(Hg)emissions, shall be designed and operated with two beds in series,with the second bed serving as a guard bed.While
operating the carbon beds,the facility shall replace the carbon in each bed before it has reached the end of its useful life.For the
replacement of carbon in the primary bed,the secondary bed will be rotated into the primary bed position and the new carbon will be
used in the secondary bed position. In addition,the facility shall use the type of activated carbon used during the most recent
performance test demonstrating compliance with the Hg emission limit until a subsequent performance test is conducted.The facility
may substitute at any time a different brand of activated carbon,if the replacement has equivalent or improved properties compared to
the carbon used in the most recent performance test.The facility shall monitor the performance of the carbon beds in each system to
ensure that the carbon in each bed has not reached the end of its useful life.The monitoring shall be conducted consistent with the
manufacturer's specifications and recommendations.The facility shall document the monitoring procedures used and keep records of
any performance monitoring.According to the records,the carbon in CD05 and CD06 was charged on January 8,2018 and February
8,2018,respectively.Both contain Calgon carbon,which was considered an equivalent replacement for Jacobi carbon.The carbon is
washed every 3-4 weeks to increase its useful life.The facility appears to be in compliance.
Condition 2.1.A.2.bb states that the facility shall,by January 30th of each calendar year,develop and submit to DAQ a waste
management plan that meets and follows the guidelines listed in 40 CFR 60.55c.The facility shall implement the approved waste
management plan in its entirety.In addition,the waste management plan shall address the management of dental waste.The last
annual report received on January 29,2018 contained the facility's waste management plan which was most recently revised on
November 11,2005.Pages 3-5 of the plan specifically address the management of dental waste.The facility appears to be in
compliance.
Condition 2.1.A.2.cc states that the facility shall comply with 15A NCAC 02D.0535 "Excess Emissions Reporting and
Malfunctions".Emissions from bypass conditions shall not be exempted by 15A NCAC 02D.0535(c)or(g).Rule 2D.0535 requires
the facility to notify the DAQ of any source causing an excess of emissions lasting more than four hours and that results from a
malfunction,a breakdown of process or control equipment,or any other abnormal conditions.According to the semi-annual report
received January 29,2018,ESO1 and ES02 had 1.18 and 1.05 hours of excess emissions,respectively,in CY2017.The excess
emissions from both units occurred during bypass stack openings,and therefore not exempt as previously mentioned.The facility was
issued NOV/NREs regarding these bypass events.Further details are contained in the Compliance History section of this report.
Condition 2.1.A.2.dd states that the facility may operate a HMIWI using only combustion controls during periods of startup and
shutdown when no waste is being combusted.During such periods,the Permittee shall monitor and record the following: verify that
no waste is being combusted;the secondary chamber temperature;and the amount and type of fuel being combusted.The facility's
DAS monitor's and records these parameters any time the HMIWI are in operation.Therefore,verifying compliance with this
alternate operating scenario is ensured.Based on the facility's operation records,the facility appears to be in compliance.
Condition 2.1.A.2.ee states that the facility shall not allow a HMIWI to operate at any time unless a fully trained and qualified
HMIWI operator is accessible,either at the facility or available within one hour.The trained and qualified HMIWI operator may
operate the HMIWI directly or be the direct supervisor of one or more HMIWI operators.Operator training and qualification shall be
obtained by completing the requirements of 40 CFR 60.53c(c)through(g).The facility shall maintain,all items required by 40 CFR
60.53c(h)(1)through(h)(10).The facility shall establish a program for reviewing this information annually with each HMIWI
operator.This information shall be kept in location readily accessible for all HMIWI operators.During the inspection,training
materials,required documents,and names of the operators were reviewed and found to be complete.Refresher training was last
conducted at the facility on November 1 and 3,2017.
Conditions 2.1.A.2.ff and gg state the recordkeeping requirements for the facility.The records shall be kept for a period of at least
five years and maintained on-site to be made available to an authorized representative upon request.All required records were
reviewed and found to be complete.All records have been discussed in previous sections of this report.The facility appears to be in
compliance.
Conditions 2.1.A.2.hh and ii state the reporting requirements for the facility.The facility shall submit a semi-annual summary report
of monitoring and recordkeeping activities postmarked on or before January 30 and July 30 of each calendar year for the preceding
24-month period. All instances of deviations from the requirements of this permit must be clearly identified.The report shall include:
Page 9 of 13

• The values for the site-specific operating parameters;
• The highest maximum operating parameter and the lowest minimum operating parameter,as applicable,for each operating
parameter recorded for the calendar year being reported and for the previous calendar year;
• If a performance test was conducted during the reporting period,the results of the test shall be included;
• Dates where monitoring data was not collected,indicated exceedances,or indicated a malfunction;and
• If no exceedances or malfunctions occurred during the calendar year being reported,a statement to that effect shall be
included in the report.
As previously mentioned,the last semi-annual report was received on January 29,2018 and contained all the necessary elements.The
facility appears to be in compliance.
Condition 2.1.A.3 states that the HMIWI units(ES01 and ES02)are subject to 40 CFR Part 62, Subpart HHH"Federal Plan
Requirements for Hospital/Medical/Infectious Waste Incinerators Constructed On/Or Before December 1,2008."The facility shall

The facility appears to be in compliance.
B. One diesel fuel-fired emergency generator(ID No.EGl)
Condition 2.1.13.1 contains the requirements for 2D .0516 which requires the facility to limit sulfur dioxide emissions from
combustion sources, such as the emergency generator(EG1). The sulfur dioxide emissions should not exceed 2.3 pounds per million
Btu input. Diesel fuel will produce 0.29 pounds of S02 per million Btu based upon an emission factor found in AP-42 (Table 3.3-1).
The facility appears to be in compliance.
Condition 2.1.13.2. contains the requirements for 2D .0521 which requires the facility to control the visible emissions from any
emission source that may be discharged from vents or stacks. The emergency generator (EG1) was manufactured after July 1, 1971.
Therefore,the visible emissions from the generator are not to exceed 20 percent opacity when averaged over a six-minute period.The
generator was not operating during the inspection, so no visible emissions could be detected. If the generator operates according to
manufacturer specifications,it will likely be in compliance.
Condition 2.1.B.3 contains the requirements for 2D .0524 which involves the New Source Performance Standards (NSPS) federal
regulations promulgated by the EPA.The facility's diesel fuel-fired emergency generator(EG1)is subject to 40 CFR Part 60, Subpart
IHI for"Stationary Compression Ignition Internal Combustion Engines" as it was constructed after July 11, 2005, and manufactured
after April 1,2006. The generator is a certified engine according to the procedures of this subpart as verified during the inspection via
a sticker on the engine. The emission limits for the generator are 6.4 g/kW-hr of NOx+NMHC,3.5 g/kW-hr of CO, and 0.20 g/kW-hr
of PM emissions. The exhaust opacity is limited to 20%during the acceleration mode, 15%during the lugging mode,and 50%during
the peaks in either the acceleration or lugging modes.The diesel fuel is limited to a maximum sulfur content of 15 ppm(0.0015%)and
a minimum cetane index of 40 or a maximum aromatic content of 35% volume. To comply, the facility must purchase a certified
engine and operate and maintain it according to manufacturer specifications. The engine must be fitted with a non-resettable hour
meter. Operation for maintenance checks and readiness testing is limited to 100 hours per year. Operation in non-emergency situations
is allowed up to 50 hours per year, but those 50 hours are counted towards the 100 hours per year provided for maintenance and
testing.There is no time limit on the use of emergency stationary ICE in emergency situations.
The facility is required to keep records of all maintenance conducted on the engine and documentation that the engine is certified. The
facility must also keep records of the hours of operation of the engine that is recorded through the non-resettable hour meter. The
owner or operator must document how many hours are spent for emergency operation including what classified the operation as
emergency and how many hours are spent for non-emergency operation.The facility is also required to submit semi-annual summary
reports of the monitoring and recordkeeping activities.
During the inspection, the diesel fuel-fired emergency generator(EG1)was not operating. It is a 500 kW Caterpillar model DCPXL
engine. The non-resettable hours meter was recently replaced on September 23, 2016, and read 56.6 hours during the inspection.
Before being replaced,the old hour meter read 164.2 hours. Mr. Skrzypczak stated that the engine is tested twice per week for about
20 minutes. The facility is using ultra low sulfur diesel fuel(ULSD) from Alamance Oil. The facility hires Carolina CAT to service
the engine semi-annually. The engine was last fully serviced on July 20, 2017. The last semi-annual report was received on January
29,2018.According to that report,the engine ran a total of 38.3 hours in CY2017,with 36.7 hours attributed to maintenance and 1.6
hours attributed to emergency use. The facility appears to be in compliance.

Condition 2.1.B.4 contains the requirements for 2D .1111 which involves the National Emissions Standards for Hazardous Air
Pollutants (NESHAP) federal regulations promulgated by the EPA. The facility is subject to 40 CFR Part 63, Subpart ZZZZ for
"Stationary Reciprocating Internal Combustion Engines"due to the diesel fuel-fired emergency generator(EG1).Per this rule,engines
are considered"existing" if construction commenced before June 12, 2006, and are considered"new" if construction commenced on
or after this date. EG1 is considered a new source as it was constructed in July 2013 and is for emergency use only. The new engine
has no other requirements under Subpart ZZZZ, except to comply with the requirements of NSPS 40 CFR Part 60, Subpart IIII (see
Condition 2.1.13.4 below).
2.2 —Multiple Emission Source(s)Specific Limitations and Conditions
A. Facility-wide emission sources
Condition 2.2.A.1 contains the requirements for 2D.1806 which requires the facility to control and prevent odorous emissions from
causing or contributing to objectionable odors beyond the facility's boundary.If the DAQ Director determines that a source or facility
is emitting an objectionable odor,then the facility will have to implement maximum feasible controls.During the inspection,there
were not any objectionable odors encountered outdoors near the property boundaries.A review of the facility file showed that no
recent odor complaints have been received by this office.The facility appears to be in compliance.
2.3 —Permit Shield for Non Applicable Requirements
Conditions 2.3.A and B state that the facility is shielded from the following nonapplicable requirements as of the date of issuance of
this permit based on information furnished with all previous applications. This shield does not apply to future modifications or
changes in the method of operation:
• 40 CFR Part 60, Subpart Ce does not apply to this facility because this rule is specifically excluded from applicability in 15A
NCAC 02D .0524.
• 40 CFR Part 60, Subpart Ec does not apply to this facility because the HMIWIs were constructed and/or modified before the
applicability date in 40 CFR 60.56c(a).
It should be noted that sections of 40 CFR Part 60,Subparts Ce and Ec are incorporated by reference under 15A NCAC 02D .1206
"Hospital,Medical,and Infectious Waste Incinerators."This permit shield does not exempt the Permittee from complying with all

Regulation: SIP Sources require lhr particulate test runs and a minimum sample of 30 dscf. NSPS regulations may require different sample

rates,times,and temperatures. Investigate prior to test.
Process Data:It is absolutely imperative for the facility to record the pertinent data during the test so that the measured emissions can be
correlated to a production rate and compared to the permit limit. The test will be unacceptable without production data.
Method 1:If stack is between 4"-12"then Method la must be employed. If duct is<4"then alternative methods must be used(contact SSCU
with any test questions)

Remarks:
Barometric Pressure:Barometric pressure must be adjusted minus 0.1"per 100ft elevation increase or vice versa for elevation decrease.
(Elevation at which barometric pressure is measured to the elevation at the test platform.)
Orsat,Analyzer or Fyrites: The measurement of OZ&CO,is usually performed with an Orsat. However,it is acceptable to use an analyzer
if it has been calibrated per Method 3a. Fyrites are acceptable for CO,measurement. An 02 fyrite can be grudgingly accepted when the results
are used to calculate molecular weight only. In no case shall an 02 fyrite be accepted if the emission standard is in terms of lb/mmBtu or
corrected to a percentage of oxygen.
Orsat Triplicate: For each test run there must be three individual analysis of the OZ&CO,concentrations in the flue gas. The analysis must
be repeated until the following analysis criteria is met:
CO,-any three analyses differ by 02-any three analysis differ by
a)<0.3%when CO2>4.0% a)<0.3%when 02>15.0%
b)<0.2%when CO,<4.0% b)<0.26/.when Oz<15.0%

F� %C 0 Residual 1.210-1.370 Wood: 1.000-1.120.
Exit Temperature: The temperature of the dry gas leaving the impingers/condenser must be below 68F. When the ambient temperature is
above 68F it may take approximately 5 minutes for the thermal effects of the ice bath to cool the exit thermometer below 68F.
Leak Check: If the results of the leak check indicate a leak(>0.02cfm),record the leakage rate. Suggest repeating the run,but it is the
discretion of the test team and facility to accept the leak. However,the sample volume will be adversely adjusted due to the leakage rate.
Isokinetics: If the test team indicates that the isokinetic rate of a run is over 110%or under 90%,the run should be voided and repeated.
Particulate Sample Clean-up: If any particulate sample is lost during clean-up,the run should be voided and repeated.
