**Section III - Example Response**

**Compliance Methods Used**

**General Information.** The following lists compliance methods used for
the period between 9/1/98 and 2/28/99. For affected operations, the
above-mentioned facility first determined the applicability of each
operation to requirements in Subpart GG. A list of exempt operations is
available upon request but has not been included in this notification
unless specific compliance methods were required within the rule. All
Material Safety Data Sheets (MSDSs) or other technical information is
maintained on-site and is available for review upon request. The
above-mentioned facility no longer performs **chemical milling maskant
operations **in accordance with 63.747.

\(1\) **General cleaning requirements**. The facility used two general
cleaning compliance options as allowed under 63.744(a) during the
reporting period. These included using solvents that met composition
requirements and instituting work practice measures. All of the
following methods were used to determine compliance:

\(a\) Checked MSDSs and other technical data to determine if solvent
used met the criteria for aqueous or hydrocarbon based solvents under
Table 1 of 63.744(a).

\(b\) For solvents not meeting Table 1 criteria, instituted work
practices as identified in 63.744(a)(1)-(3). Posted guidance on
requirements for work practices.

\(c\) For all cleaning solvents (including those used for hand-wipe,
spray gun and flush cleaning) , maintained MSDSs and other technical
data that showed name of solvent, vapor pressure, and organic HAP
constituents as required in 63.752(b)(1).

\(2\) **Hand wipe cleaning requirements**. The facility used two wipe
cleaning compliance options as allowed under 63.744(b) during the
reporting period. These included using solvents that met composition
requirements and composite vapor pressure limits. All of the following
methods were used to determine compliance:

\(a\) Checked MSDSs and other technical data to determine if solvent
used met the criteria for aqueous or hydrocarbon based solvents under
Table 1 of 63.744(a), or met the composite vapor pressure requirements
in 63.744(b)(2).

\(b\) For blended solvents, calculated the composite vapor pressure by
following procedures in 63.750(b). Maintained calculation sheets with
appropriate MSDS.

\(c\) Tracked purchases of solvents meeting Table 1 criteria in
accordance with 63.752(b)(2), or 63.752(b)(3) for solvents meeting the
composite vapor pressure.

**Appendix A contd**

\(d\) Developed a list of exempt cleaning operations where solvents used
didn't conform to 63.744(a) or 63.744(b)(2) and tracked usage in
accordance with 63.752(b)(4).

\(3\) **Spray gun cleaning requirements**. The facility used three spray
gun cleaning compliance options as allowed under 63.744(c). These
included using enclosed system cleaning, nonatomized cleaning and
disassembled gun cleaning. All of the following methods were used to
determine compliance:

\(a\) Inspected spray gun cleaning areas to determine compliance with
allowable methods in 63.744(c)(1)-(4). Posted guidance on acceptable gun
cleaning practices.

\(b\) Performed monthly inspections on enclosed spray gun cleaners in
accordance with 63.751(a) and recorded results in accordance with
63.752(b)(5). Repaired detected leaks within 15 days or shut down
operation in accordance with 63.744(c)(1)(ii).

\(4\) **Flush cleaning requirements. ** The facility used three flush
cleaning compliance options as allowed under 63.744(d). These included
using solvents that met composition requirements, using semi-aqueous
cleaners and using an enclosed collection system. All of the following
methods were used to determine compliance:

\(a\) Checked MSDSs and other technical data to determine if solvent
used met the criteria for aqueous or hydrocarbon based solvents under
Table 1 of 63.744(a), or for semi-aqueous cleaners under 63.744(d)

\(b\) For solvents not meeting Table 1 or semi-aqueous criteria, ensured
that all flush cleaning equipment conformed to the closed system
requirements in 63.744(d). Labeled all equipment with instructions to
keep containers closed when not in use.

\(c\) Tracked purchases of solvents meeting composition requirements or
which were aqueous cleaners in accordance with 63.752(b)(2).

\(5\) **Coating requirements for organic HAP.** The facility used five
organic HAP compliance options as allowed under 63.745. These included
using appropriate application techniques, compliant coatings, low HAP
coatings, averaging and waterborne coatings. All of the following
methods were used to determine compliance:

\(a\) Posted guidance on requirements for work practices to minimizing
spills in coating and mixing areas.

\(b\) Inventoried coating application methods and removed from the
premises all application methods not listed in 63.745(f). Obtained
manufacturer instructions, or developed in-house instructions, for
application devices and instituted a required reading policy for all
users to ensure that equipment is operated in accordance with
63.745(f)(2).

# Appendix A contd

\(c\) Checked MSDSs and other technical data to determine if coatings
used met the maximum VOC/HAP content in accordance with 63.745(e)(1) -
compliant coatings, 63.741(i) - waterborne coatings, and 63.752(c)(3) -
low HAP coatings. Changed supply of coatings to pre-measured kits to
ensure "as supplied" VOC/HAP content was maintained. Limited locations
where thinning solvents were authorized and instituted recordkeeping for
"as applied" coatings.

\(d\) Maintained all of the following information: MSDSs for "as
supplied" coatings; calculations showing the value of H~i\ ~and G~i~ for
"as applied" coatings in accordance with 63.750(c) and (e); and
calculations showing the value of H~a~ and G~a~ for averaged "as
applied" coatings in accordance with 63.750(d) and (f). Tracked
purchases of coatings in accordance with 63.762(c)(2) for compliant
coatings; 63.752(c)(3)(i) for low HAP coatings; and 63.741(i) for
waterborne coatings.

**Appendix E**

### Section VII - Example Response

**Major Source Determination**

As illustrated in Section VI, the emissions during the reporting period
were below major source thresholds for affected sources subject to
Subpart GG. The above-mentioned facility doesn't expect these sources to
emit HAPs in quantities greater than the major source thresholds. The
above‑mentioned facility, however, is classified as a major source due
to its potential plant-wide emissions of trichloroethylene in quantities
greater than 10 tons per year.

**Appendix F**

**Section VIII - Example Response**

**Control Equipment**

All of the following pollution control equipment is used at affected
sources within the above-mentioned facility.

**Other Methods Used** to Control Air Pollution

The above-mentioned facility, also uses other methods to comply with
Subpart GG that don't involve using pollution control equipment. We've
identified those compliance methods below.

\[**NOTE**: The first affected source is the example. The remaining
table has been left blank for those who wish to use it.\]

**Section X(a) - Example Response**

**Other Required Information**

As indicated in Section IV, the above-mentioned facility did identify
leaks in the enclosed gun cleaners CLEAN-1and CLEAN-3 on 10/1/99.
However, equipment was repaired or shut down within the 15 days in
accordance with 63.744(c)(1)(ii).

Also, as indicated in Section IV, the above-mentioned facility recorded
the pressure drop across PAINT-2 on 11/5/98, 2ed shift out of range from
the manufacturers recommendation. However, the booth was immediately
shut down in accordance with 63.745(g)(2)(iv) and the filters replaced.

**Section X(b) - Example Response**

The following coating lines are anticipated to be used between 8/1/98 -
8/1/99.
