DISCUSSION:
On November 15, 2011, Samir Parekh and I(Alan Drake)met with Alan Skrzypczak,Plant Manager, and Don
Nuss, Regional Environmental Manager, after signing in at the front office. After a brief meeting in the conference room,
we took a facility tour to understand how they processed hospital waste shipped to their facility from nearby states.
Stericycle incinerates by batch loading. They operate 24/7, incinerating 10 batches per hour with each batch weighing
about 190 pounds. The weight scale will automatically lockout at 1910 lbs/hr to prevent a permit violation. We requested
a copy of their hospital waste weight log for that hour(see attachment)to determine whether the facility was operating at
normal load during the test. We also observed their data acquisition handling system(DAHS)and discussed their daily
calibration process. The DAHS does not perform a daily automatic calibration but relies on a technician to initiate the
process. Samir noticed that some daily calibrations were performed about 30 hours after the previous cal. We
recommended that Stericycle perform their daily cals within 24-26 hours of each other. We requested a copy of recent
CEMS daily calibrations (see attachment).We also recorded the serial/model numbers from the CO/02 CEMS (see
attached DAQ Observer's checklist)and examined the daily calibration bottles for pressure and expiration date. One
bottle's expiration date was unreadable but Mr. Skrzypczak(scrip-sack) later provided a gas certificate later(see
attachment).
We then proceeded to the test trailer where we met Jim Gray from Custom Stack Analysis. They were currently
testing Unit 2 (Unit 1 would be tested on Wednesday)and were on Run 3. I recorded the tester's CO/02 CEMS
serial/model numbers as well as their cal gas information(see attached DAQ Observer's Checklist). We could not read the
serial number of the CO CEMS due to access but Mr. Gray said he could email it to me. We asked that they would include
the interference test with their relative accuracy test audit(RATA) as well as the response time test(he said the response
time was about one minute). Mr. Gray indicated they were performing a 3-point traverse and not the 12-point traverse in
the protocol.He said that traverse was used in the protocol from the previous stack test at Stericycle. In order to observe

the test company pushing the sampling probe,we climbed a ladder and walked across a corrugated roof to the sampling
port. [Note: it was suggested we walk on the corrugated ridges for more support but I found some of them to be flimsy.]
There,we met Carlos, asked questions about the sampling system, and observed him pushing the probe after a 7-minute
interval. We then returned to the test trailer and completed the checklist.
Next,we returned to the DAHS area where Jim Gaspar demonstrated the facility's method for calculating a 12-
hour rolling average.Mr. Gaspar used one-minute data that was ported from a Microsoft Access database into a Microsoft
Excel spreadsheet. He then showed how a 720-minute block of CO data matched a 12-hour average calculated by the
system. When asked how the system averaged data during daily calibration,Mr. Gaspar indicated it assumed the readings
were zero and included them in the average. Mr. Skrzypczak indicated that it took about 15 minutes to perform a daily
calibration. We expressed two concerns:
1) The 12-hour average should be based on 12 valid hours of data,with each 15-minute quadrant of each
operating hour having at least one data point(we explained the exception for times of calibration and referred
them to 40 CFR 60, Subpart A).Mr. Gaspar disagreed with an hourly average approach and felt that a 720-
minute rolling average was acceptable. We agreed to look at the regulation later.
2) During times of calibration,zeroes cannot be used in the average calculation. After considerable discussion,
Mr. Gaspar said the system could be changed to correctly calculate the hourly average and exclude zeroes
during times of calibration.
We moved our discussion to a conference room where we had our closeout meeting. Mr. Gaspar looked up the
hourly average wording of the rule and agreed with us on its interpretation. He said that he should have the DAHS
updated within two months. There was a short discussion on the use of backup CEMS. We indicated that a backup CEMS
needed to be certified. Moreover, it needed to be certified on a specific incinerator. Stericycle felt they should be allowed
to have one backup that could be used on either incinerator. Although we said it could not,they asked us check for any
exceptions. We did not have any stack testing issues, and aside from the DAHS issues,the facility appeared to be in
compliance with the CEMS portion of the permit. A final determination will be made after the RATA is reviewed.

To calculate cylinder gas range,multiply span by corresponding percentage(0.4*span,0.6*span). The calibration gas to be used shall fall within these values. CO gases do not need
to be exactly 30%,60%,and span,but should approximate the percentages. For CO testing,the"Span'gas value can be considered 80-100%of the calibrated span. Method 10 for
carbon monoxide has slight variations from method 6c,but most test companies perform CO testing to method 6c requirements.
