Approval and Promulgation of State

Plans for Designated Facilities and

Pollutants, North Carolina; Minor

Revisions to 111(d) Regulations

AGENCY: Environmental Protection

Agency.

ACTION: Final rule.

SUMMARY: In this action, EPA is

approving revisions to three North

Carolina regulations which are part of

the North Carolina 111(d) plans for

sulfuric acid mist, total reduced sulfur,

and fluorides from primary aluminum

reduction plants. These revisions are

minor and do not change the meaning of

the current regulations.

DATES: This action will be effective

January 20, 1987 unless notice is

received within 30 days that adverse or

critical comments will be submitted.

ADDRESSES: Copies of the documents

relevant to this action are available for

public inspection at the following

locations and notice of adverse or

critical comments may be submitted to

FOR FURTHER INFORMATION CONTACT.

Janet Hayward of the EPA Region IV,

Air Programs Branch, at the above

address and telephone (404) 347-3286 or

FTS 257-3286.

SUPPLEMENTARY INFORMATION: On

December 17, 1984, the North Carolina

Division of Environmental Management

submitted numerous changes to the

North Carolina Administrative Code to

EPA for approval as part of the State

Implementation Plan (SIP). These

changes included several rule revisions

which could not be processed as

revisions to the SIP under section 110 of

the Clean Air Act (the Act), because

they dealt with "designated pollutants"

which are regulated under section 111(d)

of the Act. These rules were: 2D.0517

(Emissions from Plants Producing

Sulfuric Acid), 2D.0528 (Total Reduced

Sulfur from Kraft Pulp Mills) and

2D.0529 (Fluoride Emissions from

Primary Aluminum Reduction Plants).

North Carolina resubmitted the above

regulations on July 18, 1986, for approval

as minor changes to the State's 111(d)

plans for those designated pollutants.

There are no substantive differences in

the effect of the North Carolina air

pollution control regulations as a result

of the changes. Terms have been

changed to make them consistent with

current usage and changes have been

made in order to standardize

nomenclature and to clarify the intent

and applicability of the regulations.

EPA is publishing this action without

plior proposal because the Agency

views this as a noncontroversial

amendment and anticipates no adverse

comments. This action will be effective

60 days from the date of this Federal

Register unless, within 30 days of its

publication, notice is received that

adverse or critical comments will be

submitted.

If such notice is received, this action

will be withdrawn before the effective

date by publishing two subsequent

notices. One notice will withdraw the

final action and another will begin a

new rulemaking by announcing a

proposal of the action and establishing a

comment period. If no such comments

are received, the public is advised that

this action will be effective January 20,

1987.

Final Action

After reviewing North Carolina's

111(d) plan revisions, EPA is approving

these changes because they are routine

wording changes and have no effect on

the meaning of the regulations. Under 5

U.S.C. section 605(b), I certify that these

revisions will not have a significant

economic impact on a substantial

number of small entities. (See 46 FR

8709.)

The Office of Management and Budget

has exempted this rule from the

requirements of section 3 of Executive

Order 12291.

Under section 307(b)(1) of the Act,

petitions for judicial review of this

action must be filed in the United States

Court of Appeals for the appropriate

circuit by January 20, 1987. This action

may not be challenged later in

proceedings to enforce its requirements

(See 307(b)(2).).

Designation of Areas For Air Quality

Planning Purposes; Las Vegas Valley,

NV, Redesignation for Ozone

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Final rule.

SUMMARY: This notice takes final action

to approve the State of Nevada request

for the redesignation of the Las Vegas

Valley nonattainment area to attainment

for ozone. EPA finds that the National

Ambient Air Quality Standards

(NAAQS) for ozone have not been

violated, based on data available from

1983 to date measured in the area being

redesignated. This action updates the

attainment status for the area. Also, no

additional Part D requirements need to

be satisfied in the attainment area.

SUPPLEMENTARY INFORMATION:.

Background

On March 3, 1978 (43 FR 8962), under

paragraph 107(d)(2) of the Clean Air Act, as amended, EPA promulgated

attainment status designations for all

states. Ambient air quality data

measured in Las Vegas Valley in 1977 was provided to EPA by the State along

with a recommendation that the area be

designated nonattainment for oxidant,

in accord with paragraph 107(d)(1)(A) of

the Act. EPA designated the Las Vegas

Valley area nonattainment for oxidant.

On February 8, 1979 (44 FR 8220), the

NAAQS were revised from 0.08 ppm

oxidant, 1-hour average concentration,

not to be exceeded more than once per

year, to 0.12 ppm ozone, daily maximum

1-hour average concentration, not

expected to be exceeded more than an 1.0 times per year, averaged over the

most recent three years for which data are available. The attainment status

designation table headings at 40 CFR

Part 81 were revised accordingly.

On April 1, 1986, the State of Nevada

requested that EPA redesignate the Las

Vegas Valley area to attainment for ozone. The request indicated that the

implementation of EPA-approved

control measures had resulted in only one exceedance of the NAAQS at each

of two monitoring stations and less than

1.0 expected exceedances at each of

three sites in the last three years.

Evaluation

EPA reviewed the ozone ambient air

quality data from the three monitoring

sites in the Las Vegas Valley and found

it consistent with the data in the

redesignation request. EPA found one

exceedance of the NAAQS at each of

two of the three sites during the past

three years. The exceedances were

recorded on September 14, 1983, at the

Casino Center site and on February 15,

1985, at the Henderson monitoring site.

Based on the completeness of the data,

EPA found 0.4 and 0.3 expected

exceedances of the NAAQS, averaged

over the most recent three years at the

Las Vegas-Casino Center and

Henderson-Powerline monitoring sites,

respectively. Also no exceedances have

been measured to-date in 1986 at any Las Vegas Valley monitoring station.

The ozone implementation plan for

the Las Vegas Valley was submitted by

the State of Nevada on January 11, 1985

and fully approved on August 21, 1986

(51 FR 29923). The approved plan

contains chlorine stationary source

emission limitations and new source

review rules. These regulations, adopted

on May 18, 1984, assure EPA that the

90% reduction in chlorine emissions

obtained between 1979 and 1983 would

continue. EPA also approved the plan's demonstration (of attainment) of the

effect of the chlorine emission control

strategy on the ozone ambient air

quality concentrations in the area. EPA's

approval of the control strategy

containing these measures indicates that

the plan satisfactorily demonstrates that

these measures, when implemented, have the potential to provide the

emission reduction necessary for the

attainment and maintenance of the

designated national ambient air quality standard. The plan also contains

approved control measures for volatile

organic compounds, as required by EPA,

to ensure that ozone caused by the more

traditional precursors is controlled.

Thus, EPA concludes, as did the State,

that the implementation of federally

enforceable control measures has

resulted in air quality better than that

needed for redesignation of the area.

Thus, EPA concurs with the

redesignation of the area from

nonattainment to attainment for ozone.

EPA Action

This notice takes final action to

redesignate the Las Vegas Valley,

Nevada, from nonattainment to

attainment for ozone, as requested by

the State.

Direct Final

EPA's approval of the above

redesignation in Nevada is being done

without prior proposal because the

redesigation is not considered to be

controversial. The public should be

advised that this approval action will be

effective 60 days from the date this

approval is published in the Federal

Register. However, if notice is received

by EPA within 30 days indicating that

someone wishes to submit adverse or

cirtical comments, this approval action

will be withdrawn and a subsequent

notice will be published before the

effective date. The subsequent notice

will indefinitely postpone the effective

date, modify the final action to a

proposed action, and establish a

comment period.

Regulatory Process

The Office of Management and Budget

has exempted this action from the

requirements of section 3 of Executive

Order 12291.

Under section 307(b)(1) of the Act,

petitions for judicial review of this

action must be filed in the United States

Court of Appeals for the appropriate

circuit by January 20, 1987. This action

may not be challenged later in

processing to enforce its requirements

(See 307(b)(2)).

Under 5 U.S.C. 605(b), I certify that

this action will not have a significant

economic impact on a substantial

number of small business entities. [46

FR 8709].
