22. The facility maintains records of the amount of medical waste received by package, generator information, date
received, date treated, and disposal facility. Records of medical waste transferred are also maintained. Records
were observed for July 1, 2017 through February 21, 2018. The amount of medical waste received during that
period is 15,295.4 lbs. Currently, medical waste received equals medical waste transferred.
23. The facility maintains receipts from the medical waste hauler, stamped by Curtis Bay Energy, verifying medical
waste treatment/destruction.
24. The facility annual report (FAR) was received by the SWS, dated July 5, 2017. Facility throughput for July 2016
through June 2017 is 6.3 tons. The facility had 4.3 tons of medical waste hauled to Assured Waste Solutions LLC
Medical Waste Treatment Facility (Permit No. 36-15) and 2 tons hauled to the Curtis Bay Energy – Incinerator.
25. When the facility is in operation, disinfected shredded medical waste will be hauled to the Uwharrie Regional
Landfill (62-04) in Montgomery County.
26. The facility uses the Ozonator Industries model number NG-3000 for the disinfection of medical waste. It is a
sealed processing unit. The ozonator shreds then treats medical waste with up to 10,000 ppm of ozone achieving
99.9999 percent disinfection in ~ 15 minutes (process run time is ~ 30 minutes) and a reduction in volume by up to
90 percent. Disinfected shredded medical waste is stored in the sealed roll-off container.
27. The facility has one roll-off container for the containment of disinfected shredded medical waste. The roll-off
container is a vacuum sealed unit attached to the ozonator. Mr. Kaufman stated that when the ozonator is in
operation the shredded medical waste in the roll-off container is infused with ozone, thus continually being
disinfected. This process furthers the breakdown of latex, plastics, and other compounds.
28. The sealed roll-off container has a small window used to verify when it is full. When the roll-off container is hauled
to the landfill the ozonator does not operate. The disinfected shredded medical waste in the attached sealed roll-off
container is integral to the ozonator. Disinfected shredded medical waste is not considered stored until the roll-off
container is removed from the ozonator, at which time it is hauled-off for disposal.
29. The ozonator is designed to treat medical waste containing 20 percent liquids. An absorbent material can be added
to the feed-hopper for medical waste containing > 20 percent liquids. Mr. Kaufman stated that the Ozone Waste
Solutions client service agreement requires that medical waste contain the required percent liquids.
30. Ozonator processing efficacy is verified via a 3M 1924 rapid readout test and a MesaStrip test. Each test uses
biological indicators containing bacillus atrophaeus spores. The rapid readout tests are conducted at the facility.
Mr. Kaufman stated that he was trained to conduct the rapid readout test by their company chemical technician who
was trained by the ozonator manufacturer. Rapid readout tests will be conducted monthly when the ozonator is
back in operation and the MesaStrip test will be sent off twice a year (six-month intervals) to a certified
microbiology laboratory.
31. The facility shall notify the SWS when the ozonator resumes operation.
32. A Rapid readout test and a MesaStrip test shall be conducted, proven to achieve disinfection, prior to resuming
operation of the ozonator.
33. The facility has a scale. The scale was calibrated by J.A. King and Company, LLC on December 13, 2017.
34. Medical waste received is off-loaded and inspected, weighed, logged-in, and placed on a manual roller conveyor.
Each box is opened, one at a time, at the processing table. The plastic bag is placed in the ozonator feed-hopper
and the box is flattened and placed on top. The percent liquid of the medical waste is estimated by the weight and
feel of the bag and absorbent material is added if necessary.
35. Facility personnel wear a Tyvek suit and facemask during the medical waste treatment process. Solid Waste Section
staff can observe facility operations from large office windows overlooking the processing floor.
36. The ozonator processing cycle maximum feed-hopper weight is < 500 lbs of medical waste. Each feed-hopper
commonly contains ~ 120 lbs per processing cycle.
37. The controls for the ozonator are automated and the process will stop if a sensor fails. The feed hopper moves
hydraulically up to the ozonator and dumps medical waste into a secondary hopper to be treated.
38. Mr. Kaufman stated that the ozonator unit emits ozone that is converted back to oxygen and does not require a DAQ
permit.
39. Mr. Kaufman stated that the ozonator unit and the medical waste processing operation does not require floor
drains/drainage to a treatment tank or city sewer. Medical waste spill kits and absorbent material will be used to
clean plastic trays and liquids in the event of a spill, leaking box, etc. The waste material will then be placed in the
ozonator to be disinfected.

40. Mr. Kaufman stated that if medical waste leaks or spills in the refrigerated transport truck it will be cleaned with a
medical waste spill kit and the waste material placed in the ozonator to be disinfected.
41. Medical waste spill kits/supplies were observed for facility and route truck use.
42. Mr. Kaufman stated that the facility trucks contain a copy of the contingency plan and have universal biohazard
symbol placards.
43. The facility waste screening process consists of: generator requirements to properly package and label boxes,
driver(s) trained to reject boxes if leaking, inaccurately packaged, or incorrectly labeled, client contract
requirement to abide by waste acceptance rules, company sales personnel educating clients, and the removal of
plastic bags from boxes prior to ozonation allowing staff to deduce the contents by weight and feel.
44. In the event of an unscheduled shutdown medical waste will be transferred to other medical waste treatment
facilities or direct-hauled to medical waste treatment facilities upon pickup.
45. The building is locked which secures the medical waste ozonator and processing/storage area.
46. The facility has a proper sign.
47. The PTO expiration date is March 25, 2019.
48. The PTO renewal application shall be submitted to the SWS by September 25, 2018. Contact Ming-Tai Chao,
Environmental Engineer – SWS, at 919-707-8251 for discussion regarding the renewal application process.
