South. Follow US 601 South for approximately'/2 mile. Turn left onto Mall Dr NE. After a short
distance(approx 100 feet)the road forks,bear right onto Medical Park Dr NE. The Energy Center is
located at the corner of Medical Park Dr.NE and Lake Concord Rd NE. All the permitted equipment is
located in the hospital's Energy Center.
The Facility Contact is located in Charlotte so it is recommended to make contact with the Facility
Contact prior to arriving at the facility.
Safety Equipment: No specific requirements for safety equipment.
Safety Issues: No safety issues were noted by me during the inspection.
Lat/Long: A review of the facility's coordinates on"Maps of DAQ Regulated Facilities"
indicates the facility's latitude and longitude coordinates are accurate and are locked in IBEAM.
Email Contacts: Email contacts found in IBEAM were verified.No changes to email address are needed
at this time. However,the mailing address has changed. See Section 2.below for changes.
1. The purpose of this site visit was to conduct a routine air quality inspection of Atrium Health Cabarrus. I
arrived at the facility on June 21,2022 at approximately 10:00 am. Atrium Health Cabarrus is a hospital
that utilizes four steam boilers for heating, food processing, and sterilization(non ethylene oxide)
purposes; and five emergency generators. Mr. Greg Mackin,Plant Operations Support Services, and Mr.
David Rhodes,Energy Plant Operator, accompanied me during this inspection.
2. Facility Contact Information:
During the inspection I verified the facility contact information in IBEAM. The address for the Facility
Contact and Technical Contact,Mr. Greg Mackin,has changed to 9401 Arrowpoint Blvd, Charlotte,NC
28273. 1 made the change in IBeam.
3. Compliance history file review:

8. NSPS/NESHAP Review
The emergency engines(ID Nos. 11,12,13,14,and 15)are considered new with regard to NESHAP
Subpart 4Z and comply with NESHAP 4Z by complying with NSPS 4I.
Four existing natural gas/No. 2 fuel oil-fired boilers(ID Nos. B1,B2,B3, and B4) are not subject to the
NESHAP Subpart JJJJJJ because the facility stated the four boilers(ID Nos. B 1,B2,B3, and B4)will
combust No. 2 fuel oil only during times of curtailment, emergencies and periodic testing. Records are
being kept to demonstrate that the limit of 48 hours per calendar year on fuel oil is not being exceeded.
The facility does not have any gasoline storage tanks. Therefore,the facility is not subject to NESHAP
Subpart 6C.
The facility does not sterilize equipment with ethylene oxide. Therefore,the facility is not subject to
NESHAP Subpart 5W.
