National Emission Standards for Hazardous Air Pollutants:
Halogenated Solvent Cleaning; Correction
AGENCY: Environmental Protection Agency (EPA).
ACTION: Corrections to final regulation.
-----------------------------------------------------------------------
SUMMARY: This action corrects errors and clarifies regulatory text in
the final rule published on December 2, 1994 at 59 FR 61801.
EFFECTIVE DATE: These corrections become effective June 5, 1995.
FOR FURTHER INFORMATION CONTACT:
Paul Almodovar, Coatings and Consumer Products Group, Emission
Standards Division (MD-13), U.S. Environmental Protection Agency,

SUPPLEMENTARY INFORMATION: On December 2, 1994 (59 FR 61801), the
Environmental Protection Agency (EPA) promulgated in the Federal
Register national emission standards for hazardous air pollutants for
halogenated solvent cleaning. These standards were promulgated as
subpart T in 40 CFR part 63. This document contains corrections to
editorial and cross-referencing errors in the final standards. In
addition, there are corrections to clarify the applicability of the
final rule, and to clarify several definitions.
Paragraph (a) of Sec. 63.460 is revised to reflect the intent of
the final rule by clarifying that wipe cleaning activities, such as
cleaning using a rag containing halogenated solvent or a spray cleaner
containing halogenated solvent are not covered under the scope of this
regulation.
Paragraph (d) of Sec. 63.460 and the definition of an existing
source under Sec. 63.461 are being revised to clarify that any machine,
the construction or reconstruction of which was commenced on or before
November 29, 1993, that did not meet the definition of a solvent
cleaning machine on December 2, 1994, because it did not, on that date,
use halogenated hazardous air pollutant solvent liquid or vapor covered
under this subpart to remove soils, becomes an existing source when it
commences to use such liquid or vapor. The Agency intended machines
that use halogenated hazardous air pollutants solvent liquid or vapor
covered under this subpart to be subject to the regulation regardless
of when they commenced such use. This correction clarifies an oversight
in the drafting of the final rule. In addition, an existing solvent
cleaning machine moved within a contiguous facility or to another
facility under the same ownership continues to be regulated as an
existing machine.
The definition of a batch cleaning machine under Sec. 63.461 is
being revised to clarify that cross-rod degreasers are considered batch
cleaning machines. A definition of a cross-rod solvent cleaning machine
is being added to the final rule.
The definition of a solvent cleaning machine under Sec. 63.461 is
being revised to clarify that small buckets, pails, and beakers with
capacities of 7.6 liters (2 gallons) or less are not considered solvent
cleaning machines for the purpose of this subpart. The Agency did not
intend to regulate these small pieces of equipment not specifically
designed to carry out cleaning or drying operations using one of the
covered halogenated solvents. The size limit is included to ensure that
larger vessels not specifically designed to carry out cleaning or
drying operations remain subject to this final rule.
Paragraph (e)(2)(i) of Sec. 63.463 is being revised to correct the
proper units of measurement for the chilled air blanket temperature
that the freeboard refrigeration device shall at least maintain. The
chilled air blanket temperature shall be measured in deg.F, instead of
deg.F or deg.C.
Paragraph (a)(4) of Sec. 63.468 is being revised to correct an
editorial error in order to clarify the intent of the provisions.
Paragraph (j) of Sec. 63.468 is being revised to correct language
on the part 70 permitting requirements for area source batch vapor and
in-line solvent cleaning machines to clarify the intent of the
provisions.
The headings for appendix B and appendix C are being revised for
editorial errors in order to clarify the intent of the provisions.

For reasons set out in the preamble, title 40, chapter I, part 63,
subpart T of the Code of Federal Regulations is corrected as follows:
PART 63--[CORRECTED]
1. On page 61805, in the third column, 4 lines from the bottom,
Sec. 63.460(a) is corrected to add the following: ``Wipe cleaning
activities, such as using a rag containing halogenated solvent or a
spray cleaner containing halogenated solvent are not covered under the
provisions of this subpart.''
2. On page 61806, first column, starting on line 18 from the top,
Sec. 63.460(d) is corrected by adding the following sentence to the end
of the paragraph ``Except that, any machine that commences construction
or reconstruction on or before November 29, 1993, that does not use
halogenated hazardous air pollutant (HAP) solvent on December 2, 1994
shall, if the machine begins use of halogenated HAP solvent after
December 2, 1994, achieve compliance with the provisions of this
subpart no later than December 2, 1997 or 60 days after commencing use
of halogenated HAP solvent covered under this subpart whichever is
later.''
3. On page 61806, first column, starting 7 lines from the bottom,
the definition of ``batch cleaning machine'' under Sec. 63.461 is
corrected by revising the last sentence to read as follows: ``A solvent
cleaning machine, such as a ferris wheel or a cross-rod degreaser, that
clean multiple batch loads simultaneously and are manually loaded are
batch cleaning machines.''
4. On page 61806, second column, starting on the last line of the
column, the definition of ``existing'' in Sec. 63.461 is corrected to
add the following sentence to the end of the definition: ``A machine,
the construction or reconstruction of which was commenced on or before
November 29, 1993, but that did not meet the definition of a solvent
cleaning machine on December 2, 1994 because it did not use halogenated
HAP solvent liquid or vapor covered under this subpart to remove soils,
becomes an existing source when it commences to use such liquid or
vapor. A solvent cleaning machine moved within a contiguous facility or
to another facility under the same ownership, constitutes an existing
machine.''
5. On page 61806, second column, immediately following the
definition of ``cover'' in Sec. 63.461, the following definition of
``cross-rod solvent cleaning machine'' is added: ``Cross-rod solvent
cleaning machine means a batch solvent cleaning machine in which parts
baskets are suspended from `cross-rods' as they are moved through the
machine. In a cross-rod cleaning machine, parts are loaded semi-
continuously, and enter and exit the machine from a single portal.''
6. On page 61807, second column, starting on line 40 from the top,
the definition of ``solvent cleaning machine'' under Sec. 63.461 is
corrected to add the following sentence to the end of the definition:
``Buckets, pails, and beakers with capacities of 7.6 liters (2 gallons)
or less are not considered solvent cleaning machines.''
7. On page 61808, in the first column, starting on line 26 from the
top, Sec. 63.462(d) is corrected to read as follows: ``Each owner or
operator of a batch cold cleaning machine shall submit an initial
notification report as described in Sec. 63.468 (a) and (b) and a
compliance report as described in Sec. 63.468(c).''
8. On page 61810, first column, starting on the last two lines,
Sec. 63.463(e)(2)(i) is corrected to read as follows: ``If a freeboard
refrigeration device is used to comply with these standards, the owner
or operator shall ensure that the chilled air blanket temperature (in
deg.F), measured at the center of the air blanket, is no greater than
30 percent of the solvent's boiling point.''
9. On page 61814, third column, starting on line 24 from the top,
Sec. 63.468(a)(4) is corrected to read as follows: ``The date of
installation for each solvent cleaning machine or a letter certifying
that the solvent cleaning machine was installed prior to, or after,
November 29, 1993.''
10. On page 61816, second column, starting on line 3 from the top
Sec. 63.468(j) is corrected to read as follows: ``The Administrator has
determined, pursuant to the criteria under section 502(a) of the Act,
that an owner or operator of any batch cold solvent cleaning machine
that is not itself a major source and that is not located at a major
source, as defined under 40 CFR 70.2, is exempt from part 70 permitting
requirements for that source.
An owner or operator of any other solvent cleaning machine subject
to the provisions of this subpart is subject to part 70 permitting
requirements, such sources, if not major or located at major sources,
may be deferred by the State from part 70 permitting requirements for 5
years after the EPA first approves a part 70 program (i.e., until
December 9, 1999). All sources receiving deferrals shall submit permit
applications within 12 months of such date (by December 9, 2000).''
