C. Compliance history.
The facility was issued an NOWNRE on January 4, 2019 for failure to monitor and keep records
of gallons of HAP coatings used required to avoid applicability of 15A NCAC 2D .1111. A civil
penalty was assessed in the amount of $4,542.00 and later reduced through the formal EMC
process.
The facility was issued an NOV on March 26, 2018 for failure to monitor and keep records of
gallons of HAP coatings used required to avoid applicability of 15A NCAC 2D .1111.
The facility was issued an NOD on July 24, 2013 for failure to keep records of monthly usage of
HAP coatings required to avoid applicability of 15A NCAC 2D .1111 (40 CFR 63, Subpart PPPP,
NESHAP for Surface coating of plastic Parts and Products).
The facility was issued an NOV on September 9, 2013 for construction and operation prior to
obtaining an Air Quality Permit for the sanding operation for fiberglass wall panels with
associated bagfilter.
D. Operating Conditions established by Stack Testing.—N/A.
E. Records Required by Title V. During this inspection all records, required by the Title V permit,
were reviewed. The records appear to be in compliance, based on information submitted.
F. NSPS/NESHAP Review
The facility is subject to NESHAP Subpart WWWW — NESHAP for Reinforced Plastics
Composites Production. Compliance with this MACT is discussed below.
The facility also has an avoidance condition in the permit for NESHAP Subpart PPPP — Surface
Coating of Plastic Parts and Products. Compliance with this avoidance condition is discussed
below.
There are two inactive boilers that are abandoned in place. The boilers were used by the previous
owner of the building. There are no emergency generators at the facility. Therefore,NESHAP 4Z
and 6J do not apply.
The facility does not have any gasoline storage tanks onsite; therefore, is not subject to NESHAP
6C.

typically performed early in the morning. The facility also has an area for closed molding
operations. Loss of styrene emissions from closed molding is approximately 1%while loss of
styrene from open molding is approximately 17%. The resin tank is located outside the building.
Observed. The gel coat area and the laminating area were both observed in operation with no
visible emissions. The resin tank was observed at the time of inspection with no visible
emissions.
1. 15A NCAC 2D .0521: Control of Visible Emissions-
Visible emissions from each source shall not be more than 20 percent opacity when averaged
over a six-minute period. No monitoring/recordkeeping/reporting is required.
Observed. No visible emissions were observed during the time of inspection. The facility is
performing monthly visible emission although not required. The most recent observation
occurred December 11,2019. Compliance with this stipulation is indicated.
2. 15A NCAC 2D .1111: Maximum Achievable Control Technology
The Permittee shall comply with all applicable provisions contained in Environmental
Management Commission Standard 15A NCAC 2D .1111, "Maximum Achievable Control
Technology" (MACT) as promulgated in 40 CFR 63, Subpart WWWW, "National Emission
Standards for Hazardous Air Pollutants for Reinforced Plastic Composites Production,"
including Subpart A "General Provisions" as follows:
The Permittee shall limit its organic hazardous air pollutant (HAP) emissions from its open
molding,gel-coating operations(ID No. 002)as described in 63.5805(b)and Table 3 -Subpart
WWWW,which include, in part:

As specified in 40 CFR 63.5805(b), the Permittee must meet all applicable work practice
standards in Table 4 of MACT Subpart WW W W, including:
For... You must...
All cleaning operations Not use cleaning solvents that contain HAP, except
that styrene may be used as a cleaner in closed
systems, and organic HAP containing cleaners may be
used to clean cured resin from application equipment.
Application equipment includes any equipment that
directly contacts resin.
All HAP-containing materials Keep containers that store HAP-containing materials
storage operations closed or covered except during the addition or
removal of materials. Bulk HAP-containing materials
storage tanks may be vented as necessary for safety.
All mixing operations Use mixer covers with no visible gaps present in the
mixing covers, except that gaps of up to one inch are
permissible around the mixer shafts and any required
instrumentation.
Keep the mixer covers closed while actual mixing is
occurring except when adding materials or changing
covers to the mixing vessels.
The Permittee shall demonstrate that, on average, the individual organic HAP emission limits
for each unique combination of operation type and resin application method or gel coat type
are met. If all emission factors are equal to or less than their corresponding emission limits,
then the Permittee is in compliance. The results of the monitoring shall be maintained in a
logbook on-site and made available to an authorized representative upon request. Summary
reports are required to be submitted semi-annually.
Observed.The facility contracts with Value Environmental to maintain monthly emission logs
for compliance with this MACT. As shown in the below table, the facility demonstrates
compliance with this MACT on a monthly basis by determining a styrene weighted average for
all resins/gelcoats used (based on the emission factors listed in the table above) and then
determines the average styrene emissions based on materials purchased. To comply with the
requirement that prohibits the use of HAP containing solvents, the facility uses acetone as a
cleaning solvent.
The monthly logs were observed from December 2018 through November 2019. Semi-annual
reports were received on July 12, 2019 and January 28, 2019 as required. During inspection,
VOC containing materials were properly stored and covered. Compliance with this
stipulation is indicated.
