Approval and Promulgation of

Implementation Plans Georgia:

Approval of Revisions for

Transportation Control Measures

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to approve

revisions to the Georgia State

Implementation Plan (SIP) submitted

through the Department of Natural

Resources on August 29, 1997,

requesting the incorporation of five

transportation control measures (TCMs).

This action only addresses the

incorporation of one of the five TCMs

submitted for approval into the SIP.

Action was taken on the other four

TCMs in a separate rulemaking action.

The subject of this action is an

alternative fuel refueling station/park

and ride transportation center project

located in Douglas County.

In the final rules section of this

Federal Register, the EPA is approving

the State’s State Implementation Plan

(SIP) revision as a direct final rule

without prior proposal because the EPA

views this as a noncontroversial

revision amendment and anticipates no

adverse comments. A detailed rationale

for the approval is set forth in the direct

final rule. If no adverse comments are

received in response to this proposed

rule, no further activity is contemplated

in relation to this proposed rule. If EPA

receives adverse comment, the direct

final rule will be withdrawn and all

public comments received will be

addressed in a subsequent final rule

based upon this proposed rule. The EPA

will not institute a second comment

period on this document. Any parties

interested in commenting on this

document should do so at this time.

DATES: To be considered, comments

must be received by July 24, 1998.

ADDRESSES: Written comments on this

action should be addressed to Kelly

Sheckler at the Environmental

Protection Agency, Region 4 Air

Planning Branch, 61 Forsyth Street, SW,

Atlanta, Georgia 30303. Copies of

documents relative to this action are

available for public inspection during

normal business hours at the following

Federal Register / Vol. 63, No. 121 /Wednesday, June 24, 1998 / Proposed Rules 34337

1This review was conducted solely for this rule

to confirm the reasonableness of the proposed

changes based on the relative toxicity of these

compounds. The EPA has conducted no peer

review of these toxicity findings and has not

developed a consensus position regarding the actual

toxicity of these compounds.

Regulated Entities

Entities potentially regulated by this

action are owners or operators of

facilities that are engaged, either in part

or in whole, in wood furniture

manufacturing operations and that are

major sources as defined in 40 CFR part

63, subpart A, section 63.2. Regulated

categories include:

Category Examples of regulated entities

Industry ......... Facilities which are major

sources of hazardous air

pollutants (HAP) and manufacture wood furniture or

wood furniture components.

This table is not intended to be

exhaustive, but rather provides a guide

for readers regarding entities that the

EPA is now aware potentially could be

regulated by this action. Other types of

entities not listed in the table also could

be regulated. To determine whether

your facility [company, business,

organization, etc.] is regulated by this

action, you should carefully examine

the applicability criteria in section

63.800 of the NESHAP for wood

furniture manufacturing operations that

was promulgated in the Federal

Register on December 7, 1995 (60 FR

62930) and codified at 40 CFR 63

Subpart JJ. If you have questions

regarding the applicability of this action

I. Background

On December 7, 1995 (60 FR 62930),

the EPA promulgated NESHAP for wood

furniture manufacturing operations

(Wood Furniture NESHAP). These

standards were codified as subpart JJ in

40 CFR part 63. These standards

established emission limits for, among

other things, coating and gluing of wood

furniture and wood furniture

components. Three different parties, the

Chemical Manufacturers Association

(CMA), the Halogenated Solvents

Industry Alliance, Inc. (HSIA), and the

Society of the Plastics Industry, Inc.

(SPI), petitioned for judicial review of

the final rule under section 307(b) of the

Clean Air Act (the Act).

The EPA executed settlement

agreements with each of these

petitioners on December 18, 1997. In

accordance with section 113(g) of the

Act, the EPA published notice of the

petitions in the Federal Register on

December 24, 1997 (62 FR 67360). The

notice provided a 30-day opportunity

for public comment. One comment,

supporting the agreements, was

submitted.

The settlement agreement between the

EPA and the CMA requires the EPA to

conduct notice and comment

rulemaking proposing that certain glycol

ethers be removed from the list of

volatile hazardous air pollutants

(VHAP) of potential concern in table 6

of the Wood Furniture NESHAP. The

agreement also provides that the de

minimis value in table 5 for 2-

ethoxyethyl acetate be changed from 5.0

tons per year to 10.0 tons per year.

The settlement agreement between the

EPA and the HSIA requires the EPA: (1)

to conduct notice-and-comment

rulemaking in accordance with section

307(d) of the Act proposing that

perchloroethylene and trichloroethylene

be deleted from the list of pollutants

prohibited from use in cleaning and

washoff solvents under § 63.803(e) of

the regulations (table 4 of the Wood

Furniture NESHAP); and (2) to give

great weight to the recommendations of

the Science Panel of the Joint Methylene

Chloride Characterization Task Force

regarding whether a reassessment of the

cancer hazard for methylene chloride

should be undertaken based on current

scientific information. The settlement

agreement also requires the EPA to

conduct additional notice and comment

rulemaking with respect to methylene

chloride if methylene chloride is

reassessed and certain findings are

made as a result of that reassessment.

The settlement agreement between the

EPA and the SPI requires the EPA to

propose technical amendments to the

Wood Furniture NESHAP that would

remove the subheadings of

‘‘Nonthreshold Pollutants,’’ ‘‘HighConcern Pollutants,’’ and ‘‘Unrankable

Pollutants’’ in table 6, and to remove

footnote ‘‘a’’ to table 6 which relates to

these hazard ranking classifications.

This action proposes changes to the

Wood Furniture NESHAP to address the

settlement agreements discussed above.

This action also proposes clarifying

changes and corrections which were

identified after promulgation of the rule.

II. Summary of Proposed Changes

In order to affect the settlement

agreement between the EPA and the

CMA, and between the EPA and the SPI,

the EPA is proposing to revise table 6 of

the Wood Furniture NESHAP.

Table 6 lists those VHAP that are

thought to pose a high concern for

chronic toxicity. The regulations require

affected sources to track the usage levels

of these chemicals as part of their

formulation assessment plans. The EPA,

as a result of the negotiated rulemaking

process for the final rule, included in

the table 6 list only those chemicals

with a toxicity composite score of 20 or

higher.

The original table 6 excepted three

glycol ether compounds from the list of

VHAP of potential concern because of

the relatively low toxicity of these

compounds. In its challenge of the final

rule, the CMA claimed that additional

glycol ethers should be excluded from

table 6, and asked that the EPA review

toxicity data for other specified glycol

ether compounds. The settlement

agreement listed 17 other glycol ethers

which the parties agreed should not, at

this time, be considered VHAP of

potential concern under this rule

because either the EPA lacked sufficient

toxicity information on the compound

or subsequent data demonstrated a low

toxicity for the compound. Since

signing the settlement agreement, the

EPA has completed a preliminary

literature review of toxicity studies for

all of the listed compounds to determine

if any have evidence of relatively severe

toxicity. As a result of this screening

analysis, the EPA believes that the likely

hazards posed by these compounds are

probably well below the cutoff level for

treating these compounds as VHAP of

potential concern and for the purposes

of this rule should not be listed in table

6.1 Additional information on the EPA’s

toxicity review can be found in the

docket listed in the preceding

ADDRESSES section.

The original table 6 contained

subheadings for ‘‘nonthreshold’’

pollutants, ‘‘high-concern’’ pollutants,

and ‘‘unrankable’’ pollutants. These

subheadings followed the hazard

ranking classification scheme proposed

in regulations to implement the

offsetting provisions of section 112(g) of
34338 Federal Register / Vol. 63, No. 121 /Wednesday, June 24, 1998 / Proposed Rules

the Act. The EPA now believes,

however, that these subheadings, and

footnote ‘‘a’’ which relates to these

subheadings, serve no substantive

function in this rule and should be

removed from table 6. The definition of

‘‘VHAP of potential concern’’ is

proposed to be revised to reflect this

change in table 6.

Section 63.803(l)(6) is also being

proposed to be revised to eliminate the

reference to the 112(g) regulations. The

formulation assessment plan provision

in § 63.803(l)(6) requires that if, after

November 1998, an affected source uses

any VHAP of potential concern listed in

table 6, it must keep track of the annual

usage of that chemical and report to the

permitting authority if the usage

exceeds the relevant de minimis value

for that chemical. Section 63.803(l)(6)

currently references section 112(g)

regulations to determine the relevant de

minimis values. This cross-reference is

not necessary because table 6 is

proposed to be revised to include the de

minimis value for each chemical. The

de minimis values provided in table 6

are not changed from the current values

extrapolated from the proposed section

112(g) regulations.

In order to implement the settlement

agreement between the EPA and the

CMA, the EPA is also proposing to

revise table 5 to change the de minimis

level for 2-ethoxyethyl acetate from 5.0

to 10.0 tons per year. The EPA has

concluded that the toxicity for 2-

ethoxyethyl acetate is relatively low and

in the absence of a more quantitative

assessment (i.e., an inhalation reference

concentration) for this chemical, the

EPA’s hazard ranking guidelines

provide a default de minimis value of

10.0 tons per year. The proposed change

of the 2-ethoxyethyl acetate de minimis

value is thus consistent with the EPA’s

methodology.

In order to implement the settlement

agreement between the EPA and the

HSIA, the EPA is proposing to revise

table 4 of the Wood Furniture NESHAP

by removing trichloroethylene and

perchloroethylene from the list of

prohibited cleaning and washoff

solvents. The EPA intended to include

in table 4 those pollutants classified

under the EPA’s hazard ranking

methodology as Group A (known

human carcinogen) or Group B

(probable human carcinogen). The EPA

currently considers both

perchloroethylene and trichloroethylene

as intermediately classified between a

probable and possible human

carcinogen(Group B/C). The EPA is in

the process of revising its cancer risk

assessment guidelines and is currently

reassessing these pollutants. Since a

definitive assessment of the

carcinogenicity of these two chemicals

has not been finalized by the EPA, and

given the current carcinogenicity

classifications of these chemicals, the

EPA is proposing to remove them from

table 4. Note, however, that this

proposed change in Table 4 does not

imply any change in the EPA’s current

scientific evaluation of these pollutants,

nor does it carry any weight with

respect to policies adopted toward these

pollutants in other regulatory contexts.

The EPA is also taking this

opportunity to propose additional

technical and clarifying corrections to

the final rule. The EPA is proposing to

remove caprolactam from the list of

VHAP in table 2 of the rule because this

chemical has been delisted from the

HAP list in section 112(b)(1) of the Act

(61 FR 30816).

The EPA is proposing to revise the

definition of ‘‘organic solvent’’ to reflect

the EPA’s intent in the final rule to

regulate only those organic solvents

considered HAP. Since the

promulgation of the NESHAP there has

been some confusion on what organic

solvents are regulated by the rule. The

work practice standards in § 63.803(d)of

the NESHAP include requirements for

each owner or operator of a wood

furniture manufacturing facility to

develop an organic solvent accounting

system. In addition, § 63.803(f) requires

that an affected source use no more than

1.0 gallon of organic solvent per booth

to prepare the surface of the booth prior

to applying the booth coating. The

current rule defines organic solvent as

‘‘a volatile organic liquid that is used for

dissolving or dispersing constituents in

a coating or contact adhesive, adjusting

the viscosity of a coating or contact

adhesive, or cleaning equipment. When

used in a coating or contact adhesive,

the organic solvent evaporates during

drying and does not become a part of

the dried film.’’ The definition in the

final rule should be limited to those

organic solvents which are HAP.

Therefore, the EPA is proposing to add

the term ‘‘hazardous air pollutant’’ to

the definition of organic solvent (e.g.,

organic HAP solvent). Elsewhere in the

text of the rule, the EPA is proposing to

replace the term ‘‘organic solvent’’ with

the term ‘‘organic HAP solvent.’’

III. Administrative Requirements

A. Docket

Docket A–93–10 is an organized and

complete file of all of the information

submitted to, or otherwise considered

by, the EPA in the development of this

rulemaking. The docket is a dynamic

file, since material is added throughout

the rulemaking development. The

docketing system is intended to allow

members of the public to readily

identify and locate documents to enable

them to participate effectively in the

rulemaking process. The contents of the

docket serve as the record for purposes

of judicial review (except forCAA

interagency review materials)

(§ 307(d)(7)(A) of the Act, 42 U.S.C.

7607(d)(7)(A)).

B. Paperwork Reduction Act

There are no additional information

collection requirements contained in

this proposal. Therefore, approval under

the provisions of the Paperwork

Reduction Act, 44 U.S.C. 3501, et seq.,

is not required.

C. Executive Order 12866

Under Executive Order 12866, the

EPA is required to determine whether a

regulation is ‘‘significant,’’ and

therefore, subject to Office of

Management and Budget (OMB) review

and the requirements of this Executive

Order to prepare a regulatory impact

analysis. The Executive Order defines

‘‘significant regulatory action’’ as one

that is likely to result in a rule that may

(1) have an annual effect on the

economy of $100 million or more, or

adversely affect in a material way the

economy, a sector of the economy,

productivity, competition, jobs, the

environment, public health or safety, or

State, local, or Tribal governments or

communities; (2) create a serious

inconsistency or otherwise interfere

with an action taken or planned by

another agency; (3) materially alter the

budgetary impact of entitlements,

grants, user fees, or loan programs or the

rights and obligations of recipients

thereof; or (4) raise novel legal or policy

issues arising out of legal mandates, the

President’s priorities, or the principles

set forth in the Executive Order.

This action is not a ‘‘significant

regulatory action’’ within the meaning

of the Executive Order. The proposed

rule, if promulgated, is expected to

reduce the regulatory burden on

facilities by relaxing requirements

related to specified chemical

compounds and by increasing one of the

de minimis levels triggering regulatory

action. The EPA has concluded that

these changes will not significantly

impact the environment or public health

or safety.

D. Regulatory Flexibility Act

The Regulatory Flexibility Act (RFA)

generally requires an agency to conduct

a regulatory flexibility analysis of any

rule subject to notice and comment

rulemaking requirements unless the
Federal Register / Vol. 63, No. 121 /Wednesday, June 24, 1998 / Proposed Rules 34339

agency certifies that the rule will not

have a significant economic impact on

a substantial number of small entities.

Small entities include small businesses,

small not-for-profit enterprises, and

small governmental jurisdictions. This

proposed rule would not have a

significant impact on a substantial

number of small entities because the

proposed amendments impose no new

requirements on regulated entities. The

proposed changes should actually ease

the compliance burden of the Wood

Furniture NESHAP. Therefore, I certify

that this action will not have a

significant economic impact on a

substantial number of small entities.

E. Unfunded Mandates Reform Act

Title II of the Unfunded Mandates

Reform Act of 1995 (UMRA), Pub. L.

104–4, establishes requirements for

Federal agencies to assess the effects of

their regulatory actions on State, local,

and tribal governments and the private

sector. Under section 202 of the UMRA,

the EPA generally must prepare a

written statement, including a costbenefit analysis, for proposed and final

rules with ‘‘Federal mandates’’ that may

result in expenditures to State, local,

and tribal governments, in the aggregate,

or to the private sector, of $100 million

or more in any one year. Before

promulgating an EPA rule for which a

written statement is needed, section 205

of the UMRA generally requires the EPA

to identify and consider a reasonable

number of regulatory alternatives and

adopt the least costly, most costeffective or least burdensome alternative

that achieves the objectives of the rule.

The provisions of section 205 do not

apply when they are inconsistent with

applicable law. Moreover, section 205

allows the EPA to adopt an alternative

other than the least costly, most costeffective, or least burdensome

alternative if the Administrator

publishes with the final rule an

explanation why that alternative was

not adopted. Before the EPA establishes

any regulatory requirements that may

significantly or uniquely affect small

governments, including tribal

governments, it must have developed

under section 203 of the UMRA a small

government agency plan. The plan must

provide for notifying potentially

affected small governments, enabling

officials of affected small governments

to have meaningful and timely input in

the development of EPA regulatory

proposals with significant Federal

intergovernmental mandates, and

informing, educating, and advising

small governments on compliance with

the regulatory requirements.

The EPA has determined that this

proposed rule does not contain a

Federal mandate that may result in

expenditures of $100 million or more

for State, local, and tribal governments,

in aggregate, or for the private sector in

any one year. Nor does the rule

significantly or uniquely impact small

governments, because it contains no

requirements that apply to such

governments and imposes no

obligations upon them. Thus, the

requirements of the UMRA do not apply

to this rule.

The economic impact analysis

performed for the original rule showed

that the economic impacts from

implementation of the promulgated

standards would not be ‘‘significant’’ as

defined in Executive Order 12866. No

changes are being made in these

amendments that would increase the

economic impacts.

F. Executive Order 13045

Executive Order 13045 applies to any

rule that (1) has been determined to be

‘‘economically significant’’ as defined

under Executive Order 12866, and (2)

addresses an environmental health or

safety risk that has a disproportionate

effect on children. If the regulatory

action meets both criteria, the Agency

must evaluate the environmental health

or safety effects of the planned rule on

children and explain why the planned

regulation is preferable to other

potentially effective and reasonably

feasible alternatives considered by the

Agency.

This proposed rule is not subject to

Executive Order 13045, entitled

‘‘Protection of Children from

Environmental Health Risks and Safety

Risks (62 FR 19885, April 23, 1997),

because it is not an economically

significant regulatory action as defined

by Executive Order 12866, and it does

not involve decisions on environmental

health risks or safety risks that would

have a disproportionate effect on

children.

G. Executive Order 12875

Executive Order 12875 requires that,

to the extent feasible and permitted by

law, no Federal agency shall promulgate

any regulation that is not required by

statute and that creates a mandate upon

a State, local, or tribal government,

unless funds necessary to pay the direct

costs incurred by the State, local, or

tribal government in complying with the

mandate are provided by the Federal

government. The EPA has determined

that the requirements of Executive

Order 12875 do not apply to today’s

rulemaking, since no mandate is created

by this action.

H. National Technology Transfer and

Advancement Act

Section 12(d) of the National

Technology Transfer and Advancement

Act of 1995 (NTTAA), Pub. L. No. 104–

113, § 12(d) (15 U.S.C. 272 note) directs

the EPA to use voluntary consensus

standards in its regulatory activities

unless to do so would be inconsistent

with applicable law or otherwise

impractical. Voluntary consensus

standards are technical standards (e.g.,

materials specifications, test methods,

sampling procedures, and business

practices) that are developed or adopted

by voluntary consensus standards

bodies. The NTTAA directs the EPA to

provide Congress, through OMB,

explanations when the Agency decides

not to use available and applicable

voluntary consensus standards. This

proposed rulemaking does not involve

technical standards. Therefore, the EPA

is not considering the use of any

voluntary consensus standards.

operator of an affected source shall

develop an organic HAP solvent

accounting form to record:

(1) The quantity and type of organic

HAP solvent used each month for

washoff and cleaning, as defined in

§ 63.801 of this subpart;

(2) The number of pieces washed off,

and the reason for the washoff; and

(3) The quantity of spent organic HAP

solvent generated from each washoff

and cleaning operation each month, and

whether it is recycled onsite or disposed

offsite.

* * * * *

(f) Spray booth cleaning. Each owner

or operator of an affected source shall

not use compounds containing more

than 8.0 percent by weight of VOC for

cleaning spray booth components other

than conveyors, continuous coaters and

their enclosures, metal filters, or plastic

filters unless the spray booth is being

refurbished. If the spray booth is being

refurbished (that is, the spray booth

coating or other protective material used

to cover the booth is being replaced), the

affected source shall use no more than

1.0 gallon of organic HAP solvent per

booth to prepare the surface of the booth

prior to applying the booth coating.

* * * * *

(i) Line cleaning. Each owner or

operator of an affected source shall

pump or drain all organic HAP solvent

used for line cleaning into a normally

closed container.

* * * * *

(j) Gun cleaning. Each owner or

operator of an affected source shall

collect all organic HAP solvent used to

clean spray guns into a normally closed

container.

* * * * *

(l) * * *

(6) If after November 1998, an affected

source uses a VHAP of potential

concern listed in table 6 of this subpart

for which a baseline level has not been

previously established, then the

baseline level shall be established as the

de minimis level provided in that same

table for that chemical. The affected

source shall track the annual usage of

each VHAP of potential concern

identified in this paragraph that is

present in amounts subject to material

safety data sheet reporting as required

by the Occupational Safety and Health

Administration. If usage of the VHAP of

potential concern exceeds the de

minimis level listed in table 6 of this

subpart for that chemical, then the

affected source shall provide an

explanation to the permitting authority

that documents the reason for the

exceedance of the de minimis level. If

the explanation is not one of those listed

in paragraphs (l)(4)(i) through (l)(4)(iv)

of this section, the affected source shall

follow the procedures in paragraph (l)(5)

of this section.
