FACILITY OPERATIONS SUMMARY

Raw materials such as resins, solvents and pigments are mixed and processed according to product
specific requirements. Finished products are packaged in containers ranging in size from one pint to
250 gallons, stored in warehouses on site and then distributed to customers via trucks. The facility
employs roughly 100 people and is in operation with two shifts, one from 7 a.m. to 3 p.m. and
another from 3 p.m. to 11 p.m. on Monday through Saturday. The facility currently operates two
shifts but intends to start a third shift in January.

FIELD ACTIVITIES SUMMARY

I arrived at the facility on September 13, 2023, and completed a drive by surveillance inspection.
I did not observe visible emissions or detect any odors during the drive by surveillance. I made
entry at the front office at 8:20 AM and introduced myself and Ms. Cason, presented my
credentials, and provided my business card to Mr. Kuehnel. Ms. Cason and I were given a
facility safety briefing by Mr. Kuehnel. I conducted an opening conference during which I
explained that the purpose of the visit was to conduct an inspection to determine compliance
with the CAA specifically, to determine compliance with the conditions listed in Table 3. Mr.
Kuehnel notified me that Ms. Schubert was the Environmental Manager for the facility and
would not be available until the following morning. I was given a facility tour by Mr. Kuehnel. I
took photos and used the FUR camera and Ms. Cason carried the photo-ionization detector
(Pit)) during our walkthrough. After the facility tour, Ms. Cason and I left for the day. Ms.

Cason was unavailable the following day. Site sampling activities are described in the
Measurement and/or Sampling Activities section below.

I arrived at the facility on September 14, 2023, and I made entry at the front office and

introduced myself to Ms. Schubert. I presented my credentials, and I explained that after asking

for some general business information, I would review associated records demonstrating

compliance with the requirements of 40 CFR 63 Subpart CCCCCCC. I explained to Ms.

Schubert that the facility could make a claim of business confidentiality and provided her with a

Page 4 of 11


-------
Confidential Business Information form (Appendix A). Ms. Schubert did not make a claim of
confidentiality.

I reviewed the requi red records necessary to determine compliance with the regulations and
permit conditions noted in Table 3 only. I obtained copies of the records as indicated on the
Receipt for Documents (Appendix B).

I conducted a closing conference with Ms. Schubert. I provided the facility with copies of the
Confidential Business Information form and the Receipt for Documents and a small business
information sheet.

Observations and potential findings from the facility tour, and records review, and
sampling/measurement activities are noted in the Investigation Observation and Potential
Findings section below.

Measurement and/or Sampling Activities

The inspection team conducted photo-ionization sampling using a Photo-Ionization Detector
(PID) and recorded video using a FLIR Camera during the onsite inspection under my direction.
I did a bump test calibration of the PID with 100 ppm isobutylene immediately preceding the
facility walkthrough. Ms. Cason carried the PID during the facility walkthrough. We first walked
upwind of the facility then immediately downwind and then inside the production area. I carried
the FLIR Camera and recorded videos of several vents on the exterior of the building.

All environmental measurement activities were performed in accordance with the EPA Region 7
quality system. I followed manufacturer and EPA processes for instrument calibration;
Instrument calibration was documented in the instrument's logbook.

INVESTIGATION OBSERVATIONS AND POTENTIAL FINDINGS

Ambient weather, site conditions and activities were documented in field records. All
photographs are attached as Appendix I made the following observations during the
inspection. I discussed all observations with facility representatives during the closeout meeting
unless otherwise noted in the observation description.

These observations are not final compliance determinations. The EPA Region 7 Air Branch case
review team will make the final compliance determinations based on its review of this report and
other technical, regulatory, and facility information.

US Paint Corporation maintains an Intermediate Title 5 Operating Permit issued by MoDNR.
The Intermediate Title 5 Operating Permit limits the facility to emitting less than 100 tons of
VOCs and 25 tons of combined (HAP) emissions from the entire installation in any consecutive
12-month period. The facility's record of the rolling 12-month VOC and HAP emissions from
the beginning of 2021 to August 2023, are included as Appendix I). The highest total VOC
emissions reported during the time frame occurred in the 12-month period ending July 2021 and
was 55 tons. The highest total HAP emissions reported during the time frame occurred in the 12-
month period ending December 2022 and was 4.5 tons. I reviewed the emissions calculations for
the facility and the calculations appeared to be consistent with the methodology requi red by
Permit Condition PW002, in the October 5, 2022 Intermediate State Operating Permit.

I I u" 11 j)i h - 15) - standards for new and existing facilities.

§ 63.11601(a)(1) requi res that the facility operate a capture system when dry pigments which
contain compounds of cadmium, chromium, lead, or nickel are added to a process vessel or to
the grinding and milling process. According to Ms. Schubert, US Paint Corp uses dry pigments
and solids that contain chromium. These are applied in Building E-North. Dust collection hoods
are situated over the vessels where dry pigments are added and are routed to either Dust
Collector 1 (E/DC1) or Dust Collector 3(N/DC1). The remainder of the pigments and solids that
are added to process vessels are added in a paste, slurry, or liquid form.

Page 6 of 11


-------
§ 63.11601(a)(2) requires that the particulate emissions identified in § 63.11601(a)(1) are routed
to a particulate control device. The Dust collection hoods are situated over the vessels where dry
pigments are added and are routed to either Dust Collector 1 (E/DC1) or Dust Collector
3(N/DC1).

§ 63.11601(a)(3) requires that emissions from the addition of dry pigments which contain
compounds of cadmium, chromium, lead or nickel to a process vessel or to the grinding and
milling process are captured and routed to a control device or that they be in paste, slurry, or
liquid form. According to Ms. Schubert, the only addition of dry pigments occurs in Building E-
North, and those emissions are controlled by Dust Collector 1 or Dust Collector 3. All other
additions of pigments which contain chromium are already in paste or liquid form. The addition
of the paste or liquid occurs on the outside perimeter of Building-D.

§ 63.11601(a)(4) requi res that particulate emissions must be routed to a control device meeting
the requirements of § 63.11601 (a)(5) or that they be fully enclosed or that they be in solution
during the grinding and milling.

§ 63.11601(a)(5) requi res that the opacity of visible emissions from the dust particulate control
device not exceed 10 percent but this does not apply to control devices which do not vent to
atmosphere. According to Ms. Schubert, Dust Collector 1 and Dust Collector 3 contain fabric
filters which are occasionally reverse pulsed, and the dust is collected in a bin below. The air is
returned to the building and not vented to atmosphere therefore the 10% opacity limit does not
apply.

JsL	mdards for new and existing facilities.

The requirements in § 63.11601(b)(1) - (5) apply to process and storage vessels that store or
process materials contain benzene or methylene chloride. According to Ms. Schubert, the facility
does not store or process materials which contain benzene or methylene chloride.

§ 63.11602 - performance test and compliance requirements.

§ 63.11602(a)(1) specifies the requirements for the initial inspection and monitoring activities.

§ 63.11602(a)(2) specifies the ongoing compliance inspection and testing requirements.
Inspections must be conducted according to § 63.1 1602(a)(2)(i) for wet particulate control
systems and according to § 63.11602(a)(2)(ii) for dry particulate control systems. Tests must be

-------
completed as specified in § 63.11602(a)(2)(iii) and recordkeeping must be completed as
specified in § 63.11602(b) for all inspections and tests.§ 63.11602(a)(2)(i) does not apply
because there are no wet particulate control systems in use at US Paint Corporation.

§ 63.11602(b) requires that the information in § 63.11602(b)(1) through (6) be recorded for each
inspection and testing activity:

§ 63.11602(b)(1) The date, place, and time;

(2)	Person conducting the activity;

(3)	Technique or method used;

(4)	Operating conditions during the activity;

(5)	Results; and

(6)	Description of correction actions taken.

§ 63.11602(a)(2)(ii)(A) requires a weekly visible inspection of any flexible ductwork. The
information specified in § 63.11602(b) must be included.

§ 63.11602(a)(2)(ii)(B) requires inspections of rigid, stationary ductwork for leaks, and the
interior of the dry particulate control unit for structural integrity and to determine the condition
of the fabric filter (if applicable) every 12 months. The information specified in § 63.11602(b)
must be included.

I requested records sufficient to demonstrate compliance with the requirements for conducting
inspections in§ 63.11602(a)(2)(ii)(A), § 63.11602(a)(2)(ii)(B) and § 63.11602(b). Ms. Schubert
produced a document which outlines the preventative maintenance activities for the Dust
Collectors. This document is included as Appendix E. The PMs include a weekly inspection
which requi res that the employee "Check flexible duct hoses for tears, leaks, rips, etc." and a
364-day inspection which requi res the employee to "Calibrate air flow meters on all dust
collectors, check rigid stationary ductwork, interior of control unit, fabric filters." Appendix E
also includes the preventative maintenance work orders and the date for the completion for Dust
Collectors 1, 2, 3 and 4. The record provided does not have the place and time of the activity, the
technique or method used, the operating conditions during the activity, or the results of the
inspection. Corrective actions would be requi red in the event of the inspection finding an issue

with the ductwork, but that information is not included in the record so there is no way to tell
whether a corrective action should have been completed.

§ 63.11602(a)(2)(iii) requires a S-minute visual determination of emissions from the particulate
control device every 3 months using Method 22 for each particulate control device. As noted
above, § 63.11602(a)(2) requires that these test results must be recorded as specified in §
63.11602(b). According to § 63.11602(a)(2)(iii), the observations must be performed during the
addition of dry pigments and solids containing compounds of chromium to a process vessel or to
the grinding and milling equipment. Mrs. Schubert told me that the only dry pigments and solids
containing chromium added to a process vessel are added in Building E-North. As discussed
above, these dust collectors are not vented to atmosphere. The regulation is not explicit whether
the requirement to conduct a visual determination of emissions applies to a unit which is not
vented to atmosphere and not subject to the opacity limit in § 63.11601(a)(5).

I requested records to demonstrate compliance with the requirements in § 63.11602(a)(2)(iii) and
63.11602(b). Section 63.11602(b) specifies the recordkeeping requirements for the opacity
observations. Ms. Schubert provided me with a record of the Method 22 observations which she
conducted from January 2021 to September 2023. This record is included as Appendix F. Ms.
Schubert reported that she conducts the tests monthly to comply with Permit Condition 011 and
utilizes a form to record the test information. Ms. Schubert is using "Attachment F" from the
previous 2017 Operating Permit to record the test information.1 Although "Attachment F" is
titled "PW003 40 CFR Part 63 Subpart CCCCCCC", it does not have space for the information
requi red by 40 CFR 60 Appendix A-7 to Part 60, 63.11602(b)(1), or Method 22. For example,
while the form notes a start time, there is no stop time as requi red by 40 CFR 60 Appendix A-7
to Part 60, 11.5 Recording Observations. Additionally, the form does not have the place
identified as requi red by 63.11602(b)(1). Further, Method 22 requires recording:

"the following information on the field data sheet (Figure 22-1): Company name, industry,
process unit, observer's name, observer's affiliation, and date. Record also the estimated
wind speed, wind direction, and sky condition. Sketch the process unit being observed and
note the observer location relative to the source and the sun. Indicate the potential and

location.

The form contains a column for operating condition, but the operating condition of the
equipment is not listed. In this column the sky condition is recorded.

Ms. Schubert reported that she was certified to conduct Method 9 tests.

§ 63.11603 Notification, reporting, and recordkeeping requirements.

§ 63.11603(b) requi res the preparation of an annual compliance certification report but the report
does not need to be submitted unless a deviation has occurred. According to Ms. Schubert, the
facility has not reported and deviations and has never submitted the annual compliance
certification report. The report which was prepared for the 2022 calendar year is attached as
Appendix G.

§ 63.11603(c) specifies the recordkeeping requirements. These recordkeeping requirements are
addressed above and not repeated here.

40 CFR 63 Subpart T- National Emission Standards for Halogenated Solvent Cleaning

According to Ms. Schubert, the facility does not use any methylene chloride at the facility and is
therefore not subject to this subpart.

40 CFR 63 Subpart HHHHBH - National Emission Standards for Hazardous Air Pollutants:

Paint Stripping and Miscellaneous Surface Coating Operations at Area Sources

40 CFR 63 Subpart 11HHHHH applies to any facility which is engaged in any of the activities in
paragraphs (a) through (c) in § 63.11169. These include (c) Spray application of coatings
containing compounds of chromium (Or). US Paint Corporation engages in spray application of
coatings containing chromium in their spray booths. However, § 63.11169(d) lists the activities
which are exempt from this regulation including (5) surface coating that meets the definition of
"quality control activities." Quality control activities are defined as surface coating activities that
meet all of the following criteria:

(1) The activities associated with a surface coating or paint stripping operation are intended

to detect and correct defects in the final product by selecting a limited number of samples

from the operation and comparing the samples against specific performance criteria.

Page 10 of 11


-------
(2)	The activities do not include the production of an intermediate or final product for sale or
exchange for commercial profit; for example, parts that are surface coated or stripped are not
sold and do not leave the facility.

(3)	The activities are not a normal part of the surface coating or paint stripping operation; for
example, they do not include color matching activities performed during a motor vehicle
collision repair.

(4)	The activities do not involve surface coating or stripping of the tools, equipment,
machinery, and structures that comprise the infrastructure of the affected facility and that are
necessary for the facility to function in its intended capacity; that is, the activities are not
facility maintenance.

Ms. Schubert told me that the spray booths in operation at US Paint Corporation meet all of the
criteria specified in the definition of quality control activities and are exempt from the
requirements located at 40 CFR 63 Subpart HHHHHBL
