62668 Federal Register / Vol. 65, No. 203 / Thursday, October 19, 2000 / Proposed Rules

that this proposed rule will not have a

significant economic impact on a

substantial number of small entities

under the Regulatory Flexibility Act (5

U.S.C. 601 et seq.). Because this rule

proposes to approve pre-existing

requirements under state law and does

not impose any additional enforceable

duty beyond that required by state law,

it does not contain any unfunded

mandate or significantly or uniquely

affect small governments, as described

in the Unfunded Mandates Reform Act

of 1995 (Public Law 104–4). For the

same reason, this proposed rule also

does not significantly or uniquely affect

the communities of tribal governments,

as specified by Executive Order 13084

(63 FR 27655, May 10, 1998). This

proposed rule will not have substantial

direct effects on the States, on the

relationship between the national

government and the States, or on the

distribution of power and

responsibilities among the various

levels of government, as specified in

Executive Order 13132 (64 FR 43255,

August 10, 1999), because it merely

proposes to approve a state rule

implementing a federal standard, and

does not alter the relationship or the

distribution of power and

responsibilities established in the Clean

Air Act. This proposed rule also is not

subject to Executive Order 13045 (62 FR

19885, April 23, 1997), because it is not

economically significant. In reviewing

SIP submissions, EPA’s role is to

approve state choices, provided that

they meet the criteria of the Clean Air

Act. In this context, in the absence of a

prior existing requirement for the State

to use voluntary consensus standards

(VCS), EPA has no authority to

disapprove a SIP submission for failure

to use VCS. It would thus be

inconsistent with applicable law for

EPA, when it reviews a SIP submission,

to use VCS in place of a SIP submission

that otherwise satisfies the provisions of

the Clean Air Act. Thus, the

requirements of section 12(d) of the

National Technology Transfer and

Advancement Act of 1995 (15 U.S.C.

272 note) do not apply. As required by

section 3 of Executive Order 12988 (61

FR 4729, February 7, 1996), in issuing

this proposed rule, EPA has taken the

necessary steps to eliminate drafting

errors and ambiguity, minimize

potential litigation, and provide a clear

legal standard for affected conduct. EPA

has complied with Executive Order

12630 (53 FR 8859, March 15, 1988) by

examining the takings implications of

the rule in accordance with the

‘‘Attorney General’s Supplemental

Guidelines for the Evaluation of Risk

and Avoidance of Unanticipated

Takings’’ issued under the executive

order. This proposed rule to approve

permits issued by the Commonwealth of

Virginia to control NOX emissions from

the Potomac River Generating Station

and the Possum Point Generating

Station does not impose an information

collection burden under the provisions

of the Paperwork Reduction Act of 1995

(44 U.S.C. 3501 et seq.).

SUPPLEMENTARY INFORMATION:

I. Background

Pursuant to sections 182(b)(2) and

182(f) of the Clean Air Act (CAA),

Maryland is required to implement

RACT for all major NOX sources by no

later than May 31, 1995. The definition

of a major source is determined by its

size, location, the classification of that

area and whether it is located in the

ozone transport region (OTR), which is

established by the CAA. The entire State

of Maryland is included in the OTR.

The Baltimore nonattainment area and

Cecil County are classified as severe

nonattainment areas. Calvert, Charles,

Frederick, Montgomery and Prince

George’s Counties are classified as

serious ozone nonattainment areas. The

remaining counties in Maryland are

classified as marginal or in attainment.

However, under section 184 of the CAA,

at a minimum, moderate area

requirements for stationary sources,

including RACT as specified in sections

182(b)(2) and 182(f), apply throughout

the OTR. Therefore, RACT is applicable

statewide in Maryland. Section 182 of

the Act defines a major NOX source as

one that emits or has the potential to

emit 25 or more tons of NOX per year

(TPY) in any ozone nonattainment area

classified as severe, or 50 or more TPY

located in any ozone nonattainment area

classified as serious. For any area in the

OTR classified as attainment or

marginal nonattainment, sections 182

and 184 of the Act define a major

stationary source of NOX as one that

emits or has the potential to emit 100 or

more TPY.

On July 11, 1995, the Maryland

Department of the Environment (MDE)

submitted a revision to its State

Implementation Plan (SIP) for the

control of NOX emissions from major

sources. This submittal included

revisions to regulation COMAR

26.11.09.01 and 26.11.09.08 which

pertained to definitions and a ‘‘generic’’

NOX RACT rule. This generic rule

required affected sources to either meet

a presumptive NOX emissions standard

or to submit a ‘‘case-by-case’’ RACT

proposal for approval by MDE. Each

case-by-case RACT determination was

required to be the subject of a public

hearing and to be submitted to the EPA

as a SIP revision. On June 22, 1999 EPA

granted conditional limited approval of

this SIP revision (64 FR 33197). On

September 8, 2000, Maryland submitted

Federal Register / Vol. 65, No. 203 / Thursday, October 19, 2000 / Proposed Rules 62669

a SIP revision which repealed the

‘‘generic’’ RACT rule found at COMAR

26.11.09.08 and instead adopted source

category specific RACT emission

limitations at COMAR 26.11.09.08. The

submittal of the September 8, 2000, SIP

revision fulfills the conditions of the

conditional limited approval.

The September 8, 2000, SIP revision

is the subject of this action. The

September 8, 2000, submittal included

the new regulation, COMAR

26.11.09.08, which requires major NOX

sources in the entire State of Maryland

to comply with RACT requirements by

May 31, 1995, and the addition of the

definition for the term ‘‘high heat

release unit’’ to COMAR 26.11.09.01.

II. Summary of Maryland’s SIP

Revision

COMAR 26.11.09.01—Definitions

COMAR 26.11.09.01, ‘‘Definitions,’’

has been revised to add the term ‘‘high

heat release unit’’ which is used in

Chapter 09, ‘‘Control of Fuel-Burning

Equipment, Stationary Internal

Combustion Engines, and Certain FuelBurning Installations.’’

COMAR 26.11.09.08—Control of NOX

Emissions From Major Stationary

Sources

COMAR 26.11.09.08.A—Applicability

Section A establishes the applicability

of this regulation to owners or operators

of an installation that is located at a

premises that has a total potential to

emit: 25 or more TPY in Baltimore City,

Anne Arundel, Baltimore, Carroll,

Harford, Howard Counties (the

Baltimore severe nonattainment area)

and Cecil County (part of the

Philadelphia-Wilmington-Trenton

severe nonattainment area), 50 or more

TPY in Calvert, Charles, Frederick,

Montgomery, and Prince George’s

Counties (the Maryland portion of the

Washington, DC serious nonattainment

area), or 100 or more TPY in Allegany,

Caroline, Dorchester, Garrett, Kent,

Queen Anne’s, St. Mary’s, Somerset,

Talbot, Washington, Wicomico, or

Worcester Counties.

COMAR 26.11.09.08.B—General

Requirements and Conditions

Section B sets general RACT emission

standards for any major stationary

source that causes NOX emissions and is

subject to this regulation. These general

emission standards are found in Table 1.

Sections C through J of COMAR

26.11.09.08 set source category specific

RACT limitations.

TABLE 1.—EMISSION STANDARDS IN

POUNDS OF NOX PER MILLION BRITISH THERMAL UNITS (MMBTU) PER

HOUR OF HEAT INPUT

Fuel Tangential-fired Wall-fired

Gas Only ................... 0.20 0.20

Gas/Oil ...................... 0.25 0.25

Coal (dry bottom) ...... 0.38 0.38

Coal (wet bottom) ..... 1.00 1.00

The regulation requires demonstration

of compliance by either continuous

emission monitoring (CEMs) or stack

tests. Compliance via CEM shall be

determined on a 30-day rolling average.

Stack test compliance shall be

determined as averages of the stack test

duration.

EPA is proposing to approve the

above emission limits as RACT for those

major stationary sources not subject to

emission standards under any other

section of this regulation. EPA policy for

NOX RACT for four categories of utility

boilers (wall- and tangential-fired—gas/

oil, coal dry bottom), was set in the

‘‘NOX Supplement to the General

Preamble for Implementation of Title I’’

(‘‘NOX Supplement’’) (57 FR 55620,

November 25, 1992). Emission limits for

other source categories are considered

NOX RACT if comparable to RACT for

these certain utility boilers.

Comparability is based upon emission

reduction, cost and cost-effectiveness.

EPA has determined that the limits set

in Maryland’s regulation, for these same

four categories of utility boilers as in the

NOX Supplement, meet the requirement

for RACT. A source may propose an

alternative standard if the source meets

specific requirements which include: (1)

The uncontrolled NOX emissions for the

installation established with a CEM or

stack tests obtained during steady state

operation, (2) stack tests or other data

from an existing similar installation

demonstrating that the applicable

standard cannot be met, (3)

identification of all proposed

combustion, fuel or process

modifications to meet the alternative

standard and (4) equipment vendor

costs from other facilities and other

information that demonstrates that

complying with the emission standards

in the regulation is unreasonable as

compared to the cost of meeting an

alternative standard. The alternative

standard must be approved by both the

MDE and EPA.

The regulation allows for emissions

averaging for a person who owns or

operates more than one installation. The

emissions averaging provision provides

for compliance by meeting an overall

source or system-wide NOX emission

reduction that is equivalent to or greater

than the NOX emission reduction that

would be achieved if each individual

installation complied with the

applicable requirements. The sources

must have CEMs to be included in the

emission averaging and must be able to

demonstrate that on each day of

operation the total plant or system-wide

NOX emissions are equal to or less than

the NOX emissions that would be

emitted if each installation was meeting

the applicable emission standard. The

emissions averaging must be approved

by both MDE and EPA before it is

considered an acceptable compliance

method.

EPA is proposing to approve both the

alternative standards and emissions

averaging provisions of this regulation.

EPA is proposing to approve the

requirements in sections 26.11.09.08.C–

J as RACT for those categories of

sources.

COMAR 26.11.09.08.C—Requirements

for Fuel-Burning Equipment With a

Rated Heat Input Capacity of 250

MMBtu per Hour or Greater

Section C establishes that the owner

or operator of fuel-burning equipment

with a rated heat input capacity of 250

MMBtu per hour or greater equip each

installation with combustion

modifications or other technologies to

meet the following NOX emission rates

(in pounds of NOX per MMBtu per

hour): 0.45 for tangentially coal fired

units located at an electric generating

facility (excluding high heat release

units); 0.50 for wall coal fired units

located at an electric generating facility

(excluding high heat release units); 0.30

for oil fired or gas/oil fired units located

at an electric generating facility; 0.70 for

coal fired cyclone fuel burning

equipment located at an electric

generating facility from May 1 through

September 30 and 1.5 during the period

October 1 through April 30; 0.70 for a

tangentially coal fired high heat release

unit located at an electric generating

facility; 0.80 for a wall coal fired high

heat release unit located at an electric

generating facility; 0.60 for coal fired

cell burners at an electric generating

facility; and 0.70 for fuel burning

equipment stacks at an electric

generating facility during the period of

May 1 through September 30 of each

year and 0.99 during the period of

October 1 through April 30 of each year.

Compliance must be demonstrated by

operation and maintenance of a certified

NOX CEM or an alternative monitoring

method approved by both MDE and

EPA.

62670 Federal Register / Vol. 65, No. 203 / Thursday, October 19, 2000 / Proposed Rules

COMAR 26.11.09.08.D—Requirements

for Fuel-Burning Equipment With a

Rated Heat Input Capacity of Less Than

250 MMBtu per Hour and Greater Than

100 MMBtu per Hour

Section D establishes that the owner

or operator of coal burning equipment

with a rated heat input capacity of less

than 250 MMBtu per hour and greater

than 100 MMBtu per hour shall install

and operate, in accordance with

manufacturer’s specifications,

combustion modifications or other

technologies to meet an emission rate of

0.50 pounds of NOX per MMBtu per

hour. All other fuel burning equipment

with a rated heat input capacity of less

than 250 MMBtu per hour and greater

than 100 MMBtu per hour shall meet

the NOX emission rate found in COMAR

26.11.09.08B.

COMAR 26.11.09.08.E—Requirements

for Fuel Burning Equipment With a

Rated Heat Input Capacity of 100

MMBtu/hr or Less

Section E establishes that the owner

or operator of fuel burning equipment

with rated heat input capacity less than

100 MMBtu per hour must have

submitted to MDE a list of each affected

installation, the rated heat capacity of

each installation, and the fuel used. The

owner or operator must complete a

combustion analysis at least once each

calendar year and operate the

equipment at the optimum combustion

level based on this analysis. Analysis

and test results must be maintained for

at least 2 years and be available to MDE

and EPA upon request. Operators are

also required to attend operator training

on combustion optimization sponsored

by MDE, EPA or equipment vendors at

least once every 3 years, and records of

training program attendance must be

maintained and available for review.

Based on data from the Gas Research

Institute, the NOX Implementation

Workgroup, and the Council of

Industrial Boiler Owners, MDE

concluded that this section is acceptable

as RACT for fuel burning equipment

with a heat capacity of 100 MMBtu/hr

or less.

COMAR 26.11.09.08.F—Requirements

for Space Heaters

Section F establishes that an owner or

operator of a space heater must submit

to MDE a list of the affected installations

at each premises and the types of fuel

used. The owner or operator also must

develop an operating and maintenance

plan to minimize NOX emissions, based

on equipment vendors

recommendations and subject to review

by MDE. Operators are required to

attend in-state training programs on

NOX reductions at least once every three

years, and the owner must maintain a

record of training attendance for each

operator. These records should be made

available to MDE upon request. EPA

interprets ‘‘an operation and

maintenance plan to minimize NOX

emissions based on recommendations

from equipment vendors,’’ as stated in

section F(b), to mean only technically

supportable operation and maintenance

requirements that result in the

equipment being operated, maintained

and repaired in a manner that achieves

the minimization of NOX emissions.

COMAR 26.11.09.08.G—Requirements

for Fuel-Burning Equipment With a

Capacity Factor of 15 Percent or Less,

and Combustion Turbines With a

Capacity Factor Greater Than 15 Percent

Sources must certify that they meet

the capacity factors of this section.

Section G requires the performance of

an annual combustion analysis and

operation of the equipment at the

optimum combustion level based on

this analysis for fuel-burning equipment

operating over 500 hours during a

calendar year. The capacity factor must

be certified. Operators are also required

to attend operator training on

combustion optimization sponsored by

MDE, EPA or equipment vendors at

least once every 3 years, and records of

training program attendance must be

maintained and available for review.

The results of the combustion analysis

and optimization must be maintained

for at least 2 years and made available

for review. Combustion turbines with a

capacity factor of greater than 15

percent must meet an hourly average

NOX emission rate of not more than 42

ppm when burning gas or 65 ppm when

burning fuel oil or meet applicable

Prevention of Significant Deterioration

(PSD) limits, whichever is more

restrictive.

COMAR 26.11.09.08.H—Requirements

for Cement Manufacturing Facilities,

Municipal Waste Combustors, and

Hospital, Medical, and Infectious Waste

Incinerators

Section H establishes that the owner

or operator of a cement manufacturing

facility or a municipal waste combustor

shall install and maintain a NOX CEM.

Cement manufacturing kilns may not

exceed a total hourly NOX emission rate,

as determined on a 30 day rolling

average of the daily average, of 1,000

pounds for a facility with a total kiln

capacity of 600,000 tons per year or less

and 1,800 pounds for a facility with a

total kiln capacity greater than 600,000

tons per year. NOX emissions from

municipal waste combustors may not

exceed the NOX emissions standards in

COMAR 26.11.08.08 or applicable PSD

limits, whichever is more restrictive.

COMAR 26.11.09.08.I—Requirements

for Glass Melting Furnaces and Internal

Combustion Engines at Natural Gas

Pipeline Stations

Section I establishes that the owner or

operator of a glass melting furnace shall

optimize combustion by performing

daily oxygen tests and maintaining

excess oxygen at 4.5 percent or less.

Internal combustion engines at a natural

gas pipeline station with a capacity

factor of over 15 percent shall perform

either parametric optimization or engine

rebuild to meet the following emission

standards: facilities with five or less

engines shall meet a combined

maximum hourly emission rate of 300

pounds per hour and facilities with

more than five engine shall meet a

combined maximum hourly emission

rate of 566 pounds per hour. The

regulation requires that records be kept

to document the results of the daily

oxygen tests and the performance of the

parametric optimization for at least 2

years.

COMAR 26.11.09.08.J—Requirements

for Industrial Furnaces and Other

Miscellaneous Installations That Cause

Emissions of NOX

Section J establishes that the owner or

operator of any installation, other than

fuel burning equipment, that emits NOX

emissions shall: Maintain good

operating practices as recommended by

the equipment vendor to minimize NOX

emissions; prepare and implement a

written in-house training program for all

operators of these installations that

includes good operating and

maintenance practices; maintain a copy

of the written training program for

review, maintain attendance records for

each operator for at least 2 years; and

burn only gas in each installation,

where gas is available, during the period

of May 1 through September 30.

COMAR 26.11.09.08.K—Reporting

Requirements

Sources are required to submit CEM

data and stack test results to the MDE

within acceptable time limits.

Compliance with RACT requirements

should be based on CEM data certified

in accordance with 40 CFR part 60,

appendix B or part 75, appendix A. If

the installation is stack tested, Method

7 found in COMAR 26.11.01.04C(1)

must be used, and the results must be

submitted to MDE within 45 days after

test completion. The regulation also

requires that annual fuel use records be

Federal Register / Vol. 65, No. 203 / Thursday, October 19, 2000 / Proposed Rules 62671

maintained for 3 years and made

available for review by the State. The

reporting requirements are approvable.

III. Proposed Action

EPA is proposing full approval of

Maryland’s NOX RACT regulation found

at COMAR 26.11.09.01 and 26.11.09.08

which was submitted as a SIP revision

by the Maryland Department of the

Environment on September 8, 2000.

Interested parties may participate in

the Federal rulemaking procedure by

submitting written comments to the

EPA Regional office listed in the

ADDRESSES section of this document.

Written comments must be received on

or before November 9, 2000. EPA calls

your attention to the November 9, 2000

deadline date for submittal of comments

on this proposed action to grant full

approval of this SIP revision submitted

by the State of Maryland. The EPA is

providing a shortened time period for

comment for two reasons. As an initial

matter, this revision is non-controversial

and EPA does not expect comment.

Maryland’s NOX RACT requirements are

consistent with the RACT requirements

adopted by other states and do provide

provisions for sources to apply for an

alternative RACT determination.

Moreover, this SIP revision is necessary

for full approval of the attainment

demonstration SIP for the Metropolitan

Washington, D.C. ozone nonattainment

area. The EPA is currently under an

obligation to complete rulemaking by

November 15, 2000 fully approving the

attainment demonstration for the

Metropolitan Washington, D.C. ozone

nonattainment area or, in the

alternative, proposing a federal

implementation plan.

IV. Administrative Requirements

Under Executive Order 12866 (58 FR

51735, October 4, 1993), this proposed

action is not a ‘‘significant regulatory

action’’ and therefore is not subject to

review by the Office of Management and

Budget. This action merely proposes to

approve state law as meeting Federal

requirements and imposes no additional

requirements beyond those imposed by

state law. Accordingly, the

Administrator certifies that this rule

will not have a significant economic

impact on a substantial number of small

entities under the Regulatory Flexibility

Act (5 U.S.C. 601 et seq.). Because this

rule approves pre-existing requirements

under state law and does not impose

any additional enforceable duty beyond

that required by state law, it does not

contain any unfunded mandate or

significantly or uniquely affect small

governments, as described in the

Unfunded Mandates Reform Act of 1995

(Public Law 104–4). For the same

reason, this proposed rule also does not

significantly or uniquely affect the

communities of tribal governments, as

specified by Executive Order 13084 (63

FR 27655, May 10, 1998). This proposed

rule will not have substantial direct

effects on the States, on the relationship

between the national government and

the States, or on the distribution of

power and responsibilities among the

various levels of government, as

specified in Executive Order 13132 (64

FR 43255, August 10, 1999), because it

merely proposes to approve a state rule

implementing a federal standard, and

does not alter the relationship or the

distribution of power and

responsibilities established in the Clean

Air Act. This rule also is not subject to

Executive Order 13045 (62 FR 19885,

April 23, 1997), because it is not

economically significant.

In reviewing SIP submissions, EPA’s

role is to approve state choices,

provided that they meet the criteria of

the Clean Air Act. In this context, in the

absence of a prior existing requirement

for the State to use voluntary consensus

standards (VCS), EPA has no authority

to disapprove a SIP submission for

failure to use VCS. It would thus be

inconsistent with applicable law for

EPA, when it reviews a SIP submission,

to use VCS in place of a SIP submission

that otherwise satisfies the provisions of

the Clean Air Act. Thus, the

requirements of section 12(d) of the

National Technology Transfer and

Advancement Act of 1995 (15 U.S.C.

272 note) do not apply. As required by

section 3 of Executive Order 12988 (61

FR 4729, February 7, 1996), in issuing

this rule, EPA has taken the necessary

steps to eliminate drafting errors and

ambiguity, minimize potential litigation,

and provide a clear legal standard for

affected conduct. EPA has complied

with Executive Order 12630 (53 FR

8859, March 15, 1988) by examining the

takings implications of the rule in

accordance with the ‘‘Attorney

General’s Supplemental Guidelines for

the Evaluation of Risk and Avoidance of

Unanticipated Takings’’ issued under

the executive order. This rule, which

proposes approval of Maryland’s NOX

RACT regulation, does not impose an

information collection burden under the

provisions of the Paperwork Reduction

Act of 1995 (44 U.S.C. 3501 et seq.).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to approve

a State Implementation Plan (SIP)

revision submitted by the State of

Maryland on April 27, 2000. This

revision responds to the EPA’s

regulation entitled, ‘‘Finding of

Significant Contribution and

Rulemaking for Certain States in the

Ozone Transport Assessment Group

Region for Purposes of Reducing

Regional Transport of Ozone,’’

otherwise known as the ‘‘ NOX SIP

Call.’’ This revision establishes and

requires a nitrogen oxides (NOX)

allowance trading program for large

electric generating and industrial units,

and reductions for cement kilns and

stationary industrial combustion

engines, beginning in 2003. The

intended effect of this action has two

purposes. EPA is proposing to approve

the Maryland’s NOX Reduction and

Trading Program because it meets the

requirements of the NOX SIP Call that

will significantly reduce ozone transport

in the eastern United States. In addition,

EPA is proposing to approve the

Maryland’s NOX Reduction and Trading

Program because it supports the onehour attainment demonstration plans for

the Baltimore, Metropolitan

Washington, D.C. and PhiladelphiaWilmington-Trenton ozone

nonattainment areas.
