Regional Haze Program Requirements, 40 CFR 51.308282 40 CFR Ch. I (7–1–06 Edition) § 51.308

or major modification may have an adverse impact on visibility in any Federal Class I area. Where the State finds

that such an analysis does not demonstrate to the satisfaction of the

State that an adverse impact will result in the Federal Class I area, the

State must, in the notice of public

hearing, either explain its decision or

give notice as to where the explanation

can be obtained.

(b) The plan shall also provide for the

review of any new major stationary

source or major modification:

(1) That may have an impact on any

integral vista of a mandatory Class I

Federal area, if it is identified in accordance with §51.304 by the Federal

Land Manager at least 12 months before submission of a complete permit

application, except where the Federal

Land Manager has provided notice and

opportunity for public comment on the

integral vista in which case the review

must include impacts on any integral

vista identified at least 6 months prior

to submission of a complete permit application, unless the State determines

under §51.304(d) that the identification

was not in accordance with the identification criteria, or

(2) That proposes to locate in an area

classified as nonattainment under section 107(d)(1)(A), (B), or (C) of the Clean

Air Act that may have an impact on

visibility in any mandatory Class I

Federal area.

(c) Review of any major stationary

source or major modification under

paragraph (b) of this section, shall be

conducted in accordance with paragraph (a) of this section, and §51.166(o),

(p)(1) through (2), and (q). In conducting such reviews the State must

ensure that the source’s emissions will

be consistent with making reasonable

progress toward the national visibility

goal referred to in §51.300(a). The State

may take into account the costs of

compliance, the time necessary for

compliance, the energy and nonair

quality environmental impacts of compliance, and the useful life of the

source.

(d) The State may require monitoring of visibility in any Federal Class

I area near the proposed new stationary source or major modification

for such purposes and by such means as the State deems necessary and appropriate.

§ 51.308 Regional haze program requirements.

(a) What is the purpose of this section?

This section establishes requirements

for implementation plans, plan revisions, and periodic progress reviews to

address regional haze.

(b) When are the first implementation

plans due under the regional haze program? Except as provided in §51.309(c),

each State identified in §51.300(b)(3)

must submit, for the entire State, an

implementation plan for regional haze

meeting the requirements of paragraphs (d) and (e) of this section no

later than December 17, 2007.

(c) [Reserved]

(d) What are the core requirements for

the implementation plan for regional

haze? The State must address regional

haze in each mandatory Class I Federal

area located within the State and in

each mandatory Class I Federal area

located outside the State which may be

affected by emissions from within the

State. To meet the core requirements

for regional haze for these areas, the

State must submit an implementation

plan containing the following plan elements and supporting documentation

for all required analyses:

(1) Reasonable progress goals. For each

mandatory Class I Federal area located

within the State, the State must establish goals (expressed in deciviews) that

provide for reasonable progress towards

achieving natural visibility conditions.

The reasonable progress goals must

provide for an improvement in visibility for the most impaired days over

the period of the implementation plan

and ensure no degradation in visibility

for the least impaired days over the

same period.

(i) In establishing a reasonable

progress goal for any mandatory Class

I Federal area within the State, the

State must:

(A) Consider the costs of compliance,

the time necessary for compliance, the

energy and non-air quality environmental impacts of compliance, and the

remaining useful life of any potentially


affected sources, and include a demonstration showing how these factors

were taken into consideration in selecting the goal.

(B) Analyze and determine the rate of

progress needed to attain natural visibility conditions by the year 2064. To

calculate this rate of progress, the

State must compare baseline visibility

conditions to natural visibility conditions in the mandatory Federal Class I

area and determine the uniform rate of

visibility improvement (measured in

deciviews) that would need to be maintained during each implementation period in order to attain natural visibility conditions by 2064. In establishing the reasonable progress goal,

the State must consider the uniform

rate of improvement in visibility and

the emission reduction measures needed to achieve it for the period covered

by the implementation plan.

(ii) For the period of the implementation plan, if the State establishes a

reasonable progress goal that provides

for a slower rate of improvement in

visibility than the rate that would be

needed to attain natural conditions by

2064, the State must demonstrate,

based on the factors in paragraph

(d)(1)(i)(A) of this section, that the rate

of progress for the implementation

plan to attain natural conditions by

2064 is not reasonable; and that the

progress goal adopted by the State is

reasonable. The State must provide to

the public for review as part of its implementation plan an assessment of the

number of years it would take to attain natural conditions if visibility improvement continues at the rate of

progress selected by the State as reasonable.

(iii) In determining whether the

State’s goal for visibility improvement

provides for reasonable progress towards natural visibility conditions, the

Administrator will evaluate the demonstrations developed by the State pursuant to paragraphs (d)(1)(i) and

(d)(1)(ii) of this section.

(iv) In developing each reasonable

progress goal, the State must consult

with those States which may reasonably be anticipated to cause or contribute to visibility impairment in the

mandatory Class I Federal area. In any

situation in which the State cannot agree with another such State or group

of States that a goal provides for reasonable progress, the State must describe in its submittal the actions

taken to resolve the disagreement. In

reviewing the State’s implementation

plan submittal, the Administrator will

take this information into account in

determining whether the State’s goal

for visibility improvement provides for

reasonable progress towards natural

visibility conditions.

(v) The reasonable progress goals established by the State are not directly

enforceable but will be considered by

the Administrator in evaluating the

adequacy of the measures in the implementation plan to achieve the progress

goal adopted by the State.

(vi) The State may not adopt a reasonable progress goal that represents

less visibility improvement than is expected to result from implementation

of other requirements of the CAA during the applicable planning period.

(2) Calculations of baseline and natural

visibility conditions. For each mandatory Class I Federal area located within the State, the State must determine

the following visibility conditions (expressed in deciviews):

(i) Baseline visibility conditions for

the most impaired and least impaired

days. The period for establishing baseline visibility conditions is 2000 to 2004.

Baseline visibility conditions must be

calculated, using available monitoring

data, by establishing the average degree of visibility impairment for the

most and least impaired days for each

calendar year from 2000 to 2004. The

baseline visibility conditions are the

average of these annual values. For

mandatory Class I Federal areas without onsite monitoring data for 2000–

2004, the State must establish baseline

values using the most representative

available monitoring data for 2000–2004,

in consultation with the Administrator

or his or her designee;

(ii) For an implementation plan that

is submitted by 2003, the period for establishing baseline visibility conditions for the period of the first longterm strategy is the most recent 5-year

period for which visibility monitoring

data are available for the mandatory

Class I Federal areas addressed by the

plan. For mandatory Class I Federal


areas without onsite monitoring data,

the State must establish baseline values using the most representative

available monitoring data, in consultation with the Administrator or his or

her designee;

(iii) Natural visibility conditions for

the most impaired and least impaired

days. Natural visibility conditions

must be calculated by estimating the

degree of visibility impairment existing under natural conditions for the

most impaired and least impaired days,

based on available monitoring information and appropriate data analysis

techniques; and

(iv)(A) For the first implementation

plan addressing the requirements of

paragraphs (d) and (e) of this section,

the number of deciviews by which baseline conditions exceed natural visibility conditions for the most impaired

and least impaired days; or

(B) For all future implementation

plan revisions, the number of deciviews

by which current conditions, as calculated under paragraph (f)(1) of this

section, exceed natural visibility conditions for the most impaired and least

impaired days.

(3) Long-term strategy for regional

haze. Each State listed in §51.300(b)(3)

must submit a long-term strategy that

addresses regional haze visibility impairment for each mandatory Class I

Federal area within the State and for

each mandatory Class I Federal area

located outside the State which may be

affected by emissions from the State.

The long-term strategy must include

enforceable emissions limitations,

compliance schedules, and other measures as necessary to achieve the reasonable progress goals established by

States having mandatory Class I Federal areas. In establishing its longterm strategy for regional haze, the

State must meet the following requirements:

(i) Where the State has emissions

that are reasonably anticipated to contribute to visibility impairment in any

mandatory Class I Federal area located

in another State or States, the State

must consult with the other State(s) in

order to develop coordinated emission

management strategies. The State

must consult with any other State having emissions that are reasonably anticipated to contribute to visibility impairment in any mandatory Class I

Federal area within the State.

(ii) Where other States cause or contribute to impairment in a mandatory

Class I Federal area, the State must

demonstrate that it has included in its

implementation plan all measures necessary to obtain its share of the emission reductions needed to meet the

progress goal for the area. If the State

has participated in a regional planning

process, the State must ensure it has

included all measures needed to

achieve its apportionment of emission

reduction obligations agreed upon

through that process.

(iii) The State must document the

technical basis, including modeling,

monitoring and emissions information,

on which the State is relying to determine its apportionment of emission reduction obligations necessary for

achieving reasonable progress in each

mandatory Class I Federal area it affects. The State may meet this requirement by relying on technical analyses

developed by the regional planning organization and approved by all State

participants. The State must identify

the baseline emissions inventory on

which its strategies are based. The

baseline emissions inventory year is

presumed to be the most recent year of

the consolidate periodic emissions inventory.

(iv) The State must identify all anthropogenic sources of visibility impairment considered by the State in developing its long-term strategy. The

State should consider major and minor

stationary sources, mobile sources, and

area sources.

(v) The State must consider, at a

minimum, the following factors in developing its long-term strategy:

(A) Emission reductions due to ongoing air pollution control programs, including measures to address reasonably

attributable visibility impairment;

(B) Measures to mitigate the impacts

of construction activities;

(C) Emissions limitations and schedules for compliance to achieve the reasonable progress goal;

(D) Source retirement and replacement schedules;


(E) Smoke management techniques

for agricultural and forestry management purposes including plans as currently exist within the State for these

purposes;

(F) Enforceability of emissions limitations and control measures; and

(G) The anticipated net effect on visibility due to projected changes in

point, area, and mobile source emissions over the period addressed by the

long-term strategy.

(4) Monitoring strategy and other implementation plan requirements. The State

must submit with the implementation

plan a monitoring strategy for measuring, characterizing, and reporting of

regional haze visibility impairment

that is representative of all mandatory

Class I Federal areas within the State.

This monitoring strategy must be coordinated with the monitoring strategy

required in §51.305 for reasonably attributable visibility impairment. Compliance with this requirement may be

met through participation in the Interagency Monitoring of Protected Visual

Environments network. The implementation plan must also provide for the

following:

(i) The establishment of any additional monitoring sites or equipment

needed to assess whether reasonable

progress goals to address regional haze

for all mandatory Class I Federal areas

within the State are being achieved.

(ii) Procedures by which monitoring

data and other information are used in

determining the contribution of emissions from within the State to regional

haze visibility impairment at mandatory Class I Federal areas both within

and outside the State.

(iii) For a State with no mandatory

Class I Federal areas, procedures by

which monitoring data and other information are used in determining the

contribution of emissions from within

the State to regional haze visibility

impairment at mandatory Class I Federal areas in other States.

(iv) The implementation plan must

provide for the reporting of all visibility monitoring data to the Administrator at least annually for each mandatory Class I Federal area in the

State. To the extent possible, the State

should report visibility monitoring

data electronically. (v) A statewide inventory of emissions of pollutants that are reasonably

anticipated to cause or contribute to

visibility impairment in any mandatory Class I Federal area. The inventory must include emissions for a baseline year, emissions for the most recent year for which data are available,

and estimates of future projected emissions. The State must also include a

commitment to update the inventory

periodically.

(vi) Other elements, including reporting, recordkeeping, and other measures, necessary to assess and report on

visibility.

(e) Best Available Retrofit Technology

(BART) requirements for regional haze

visibility impairment. The State must

submit an implementation plan containing emission limitations representing BART and schedules for compliance with BART for each BART-eligible source that may reasonably be

anticipated to cause or contribute to

any impairment of visibility in any

mandatory Class I Federal area, unless

the State demonstrates that an emissions trading program or other alternative will achieve greater reasonable

progress toward natural visibility conditions.

(1) To address the requirements for

BART, the State must submit an implementation plan containing the following plan elements and include documentation for all required analyses:

(i) A list of all BART-eligible sources

within the State.

(ii) A determination of BART for

each BART-eligible source in the State

that emits any air pollutant which

may reasonably be anticipated to cause

or contribute to any impairment of visibility in any mandatory Class I Federal area. All such sources are subject

to BART.

(A) The determination of BART must

be based on an analysis of the best system of continuous emission control

technology available and associated

emission reductions achievable for

each BART-eligible source that is subject to BART within the State. In this

analysis, the State must take into consideration the technology available,

the costs of compliance, the energy and

nonair quality environmental impacts

of compliance, any pollution control


equipment in use at the source, the remaining useful life of the source, and

the degree of improvement in visibility

which may reasonably be anticipated

to result from the use of such technology.

(B) The determination of BART for

fossil-fuel fired power plants having a

total generating capacity greater than

750 megawatts must be made pursuant

to the guidelines in appendix Y of this

part (Guidelines for BART Determinations Under the Regional Haze Rule).

(C) Exception. A State is not required

to make a determination of BART for

SO 2 or for NO X if a BART-eligible

source has the potential to emit less

than 40 tons per year of such pollutant(s), or for PM 10 if a BART-eligible

source emits less than 15 tons per year

of such pollutant.

(iii) If the State determines in establishing BART that technological or

economic limitations on the applicability of measurement methodology to

a particular source would make the imposition of an emission standard infeasible, it may instead prescribe a design,

equipment, work practice, or other

operational standard, or combination

thereof, to require the application of

BART. Such standard, to the degree

possible, is to set forth the emission reduction to be achieved by implementation of such design, equipment, work

practice or operation, and must provide

for compliance by means which achieve

equivalent results.

(iv) A requirement that each source

subject to BART be required to install

and operate BART as expeditiously as

practicable, but in no event later than

5 years after approval of the implementation plan revision.

(v) A requirement that each source

subject to BART maintain the control

equipment required by this subpart and

establish procedures to ensure such

equipment is properly operated and

maintained.

(2) A State may opt to implement an

emissions trading program or other alternative measure rather than to require sources subject to BART to install, operate, and maintain BART. To

do so, the State must demonstrate that

this emissions trading program or

other alternative measure will achieve

greater reasonable progress than would be achieved through the installation

and operation of BART. To make this

demonstration, the State must submit

an implementation plan containing the

following plan elements and include

documentation for all required analyses:

(i) A demonstration that the emissions trading program or other alternative measure will achieve greater

reasonable progress than would have

resulted from the installation and operation of BART at all sources subject

to BART in the State. This demonstration must be based on the following:

(A) A list of all BART-eligible

sources within the State.

(B) An analysis of the best system of

continuous emission control technology available and associated emission reductions achievable for each

source within the State subject to

BART. In this analysis, the State must

take into consideration the technology

available, the costs of compliance, the

energy and nonair quality environmental impacts of compliance, any pollution control equipment in use at the

source, and the remaining useful life of

the source. The best system of continuous emission control technology and

the above factors may be determined

on a source category basis. The State

may elect to consider both source-specific and category-wide information, as

appropriate, in conducting its analysis.

(C) An analysis of the degree of visibility improvement that would be

achieved in each mandatory Class I

Federal area as a result of the emission

reductions achievable from all such

sources subject to BART located within the region that contributes to visibility impairment in the Class I area,

based on the analysis conducted under

paragraph (e)(2)(i)(B) of this section.

(ii) A demonstration that the emissions trading program or alternative

measure will apply, at a minimum, to

all BART-eligible sources in the State.

Those sources having a federally enforceable emission limitation determined by the State and approved by

EPA as meeting BART in accordance

with §51.302(c) or paragraph (e)(1) of

this section do not need to meet the requirements of the emissions trading

program or alternative measure, but

may choose to participate if they meet


the requirements of the emissions trading program or alternative measure.

(iii) A requirement that all necessary

emission reductions take place during

the period of the first long-term strategy for regional haze. To meet this requirement, the State must provide a

detailed description of the emissions

trading program or other alternative

measure, including schedules for implementation, the emission reductions required by the program, all necessary

administrative and technical procedures for implementing the program,

rules for accounting and monitoring

emissions, and procedures for enforcement.

(iv) A demonstration that the emission reductions resulting from the

emissions trading program or other alternative measure will be surplus to

those reductions resulting from measures adopted to meet requirements of

the CAA as of the baseline date of the

SIP.

(v) At the State’s option, a provision

that the emissions trading program or

other alternative measure may include

a geographic enhancement to the program to address the requirement under

§51.302(c) related to BART for reasonably attributable impairment from the

pollutants covered under the emissions

trading program or other alternative

measure.

(3) A State which opts under 40 CFR

51.308(e)(2) to implement an emissions

trading program or other alternative

measure rather than to require sources

subject to BART to install, operate,

and maintain BART may satisfy the

final step of the demonstration required by that section as follows: If the

distribution of emissions is not substantially different than under BART,

and the alternative measure results in

greater emission reductions, then the

alternative measure may be deemed to

achieve greater reasonable progress. If

the distribution of emissions is significantly different, the State must conduct dispersion modeling to determine

differences in visibility between BART

and the trading program for each impacted Class I area, for the worst and

best 20 percent of days. The modeling

would demonstrate ‘‘greater reasonable

progress’’ if both of the following two

criteria are met: (i) Visibility does not decline in any

Class I area, and

(ii) There is an overall improvement

in visibility, determined by comparing

the average differences between BART

and the alternative over all affected

Class I areas.

(4) A State that opts to participate in

the Clean Air Interstate Rule cap-andtrade and trade program under part 96

AAA–EEE need not require affected

BART-eligible EGU’s to install, operate, and maintain BART. A State that

chooses this option may also include

provisions for a geographic enhancement to the program to address the requirement under §51.302(c) related to

BART for reasonably attributable impairment from the pollutants covered

by the CAIR cap-and-trade program.

(5) After a State has met the requirements for BART or implemented emissions trading program or other alternative measure that achieves more reasonable progress than the installation

and operation of BART, BART-eligible

sources will be subject to the requirements of paragraph (d) of this section

in the same manner as other sources.

(6) Any BART-eligible facility subject to the requirement under paragraph (e) of this section to install, operate, and maintain BART may apply

to the Administrator for an exemption

from that requirement. An application

for an exemption will be subject to the

requirements of §51.303(a)(2)–(h).

(f) Requirements for comprehensive periodic revisions of implementation plans for

regional haze. Each State identified in

§51.300(b)(3) must revise and submit its

regional haze implementation plan revision to EPA by July 31, 2018 and

every ten years thereafter. In each plan

revision, the State must evaluate and

reassess all of the elements required in

paragraph (d) of this section, taking

into account improvements in monitoring data collection and analysis

techniques, control technologies, and

other relevant factors. In evaluating

and reassessing these elements, the

State must address the following:

(1) Current visibility conditions for

the most impaired and least impaired

days, and actual progress made towards natural conditions during the

previous implementation period. The

period for calculating current visibility


conditions is the most recent five year

period preceding the required date of

the implementation plan submittal for

which data are available. Current visibility conditions must be calculated

based on the annual average level of

visibility impairment for the most and

least impaired days for each of these

five years. Current visibility conditions

are the average of these annual values.

(2) The effectiveness of the long-term

strategy for achieving reasonable

progress goals over the prior implementation period(s); and

(3) Affirmation of, or revision to, the

reasonable progress goal in accordance

with the procedures set forth in paragraph (d)(1) of this section. If the State

established a reasonable progress goal

for the prior period which provided a

slower rate of progress than that needed to attain natural conditions by the

year 2064, the State must evaluate and

determine the reasonableness, based on

the factors in paragraph (d)(1)(i)(A) of

this section, of additional measures

that could be adopted to achieve the

degree of visibility improvement projected by the analysis contained in the

first implementation plan described in

paragraph (d)(1)(i)(B) of this section.

(g) Requirements for periodic reports describing progress towards the reasonable

progress goals. Each State identified in

§51.300(b)(3) must submit a report to

the Administrator every 5 years evaluating progress towards the reasonable

progress goal for each mandatory Class

I Federal area located within the State

and in each mandatory Class I Federal

area located outside the State which

may be affected by emissions from

within the State. The first progress report is due 5 years from submittal of

the initial implementation plan addressing paragraphs (d) and (e) of this

section. The progress reports must be

in the form of implementation plan revisions that comply with the procedural requirements of §51.102 and

§51.103. Periodic progress reports must

contain at a minimum the following

elements:

(1) A description of the status of implementation of all measures included

in the implementation plan for achieving reasonable progress goals for mandatory Class I Federal areas both within and outside the State. (2) A summary of the emissions reductions achieved throughout the

State through implementation of the

measures described in paragraph (g)(1)

of this section.

(3) For each mandatory Class I Federal area within the State, the State

must assess the following visibility

conditions and changes, with values for

most impaired and least impaired days

expressed in terms of 5-year averages of

these annual values.

(i) The current visibility conditions

for the most impaired and least impaired days;

(ii) The difference between current

visibility conditions for the most impaired and least impaired days and

baseline visibility conditions;

(iii) The change in visibility impairment for the most impaired and least

impaired days over the past 5 years;

(4) An analysis tracking the change

over the past 5 years in emissions of

pollutants contributing to visibility

impairment from all sources and activities within the State. Emissions

changes should be identified by type of

source or activity. The analysis must

be based on the most recent updated

emissions inventory, with estimates

projected forward as necessary and appropriate, to account for emissions

changes during the applicable 5-year

period.

(5) An assessment of any significant

changes in anthropogenic emissions

within or outside the State that have

occurred over the past 5 years that

have limited or impeded progress in reducing pollutant emissions and improving visibility.

(6) An assessment of whether the current implementation plan elements

and strategies are sufficient to enable

the State, or other States with mandatory Federal Class I areas affected by

emissions from the State, to meet all

established reasonable progress goals.

(7) A review of the State’s visibility

monitoring strategy and any modifications to the strategy as necessary.

(h) Determination of the adequacy of

existing implementation plan. At the

same time the State is required to submit any 5-year progress report to EPA

in accordance with paragraph (g) of

this section, the State must also take

one of the following actions based upon


the information presented in the

progress report:

(1) If the State determines that the

existing implementation plan requires

no further substantive revision at this

time in order to achieve established

goals for visibility improvement and

emissions reductions, the State must

provide to the Administrator a negative declaration that further revision

of the existing implementation plan is

not needed at this time.

(2) If the State determines that the

implementation plan is or may be inadequate to ensure reasonable progress

due to emissions from sources in another State(s) which participated in a

regional planning process, the State

must provide notification to the Administrator and to the other State(s)

which participated in the regional

planning process with the States. The

State must also collaborate with the

other State(s) through the regional

planning process for the purpose of developing additional strategies to address the plan’s deficiencies.

(3) Where the State determines that

the implementation plan is or may be

inadequate to ensure reasonable

progress due to emissions from sources

in another country, the State shall

provide notification, along with available information, to the Administrator.

(4) Where the State determines that

the implementation plan is or may be

inadequate to ensure reasonable

progress due to emissions from sources

within the State, the State shall revise

its implementation plan to address the

plan’s deficiencies within one year.

(i) What are the requirements for State

and Federal Land Manager coordination?

(1) By November 29, 1999, the State

must identify in writing to the Federal

Land Managers the title of the official

to which the Federal Land Manager of

any mandatory Class I Federal area

can submit any recommendations on

the implementation of this subpart including, but not limited to:

(i) Identification of impairment of

visibility in any mandatory Class I

Federal area(s); and

(ii) Identification of elements for inclusion in the visibility monitoring

strategy required by §51.305 and this

section. (2) The State must provide the Federal Land Manager with an opportunity for consultation, in person and

at least 60 days prior to holding any

public hearing on an implementation

plan (or plan revision) for regional haze

required by this subpart. This consultation must include the opportunity

for the affected Federal Land Managers

to discuss their:

(i) Assessment of impairment of visibility in any mandatory Class I Federal

area; and

(ii) Recommendations on the development of the reasonable progress goal

and on the development and implementation of strategies to address visibility impairment.

(3) In developing any implementation

plan (or plan revision), the State must

include a description of how it addressed any comments provided by the

Federal Land Managers.

(4) The plan (or plan revision) must

provide procedures for continuing consultation between the State and Federal Land Manager on the implementation of the visibility protection program required by this subpart, including development and review of implementation plan revisions and 5-year

progress reports, and on the implementation of other programs having the

potential to contribute to impairment

of visibility in mandatory Class I Federal areas.

the 2009 revision to the Missouri Regional Haze Plan. The followi ng is a summary of comments

received and the Missouri Department of Na tural Resources’ corresponding responses. Any

changes to the proposed 2009 revision to the pl an are identified in the responses to the

comments.

The Missouri Department of Natural Resources’ Air Pollution Control Program recommends the

commission adopt the plan action as amended. If the commission adopts this plan action, it will

be the department’s intention to submit this re vised plan to the U.S. Environmental Protection

Agency for inclusion in the Mi ssouri State Implementation Plan.

SUMMARY OF COMMENTS: The department’s Air Pollution Control Program received

comments from the U.S. Environmental Protec tion Agency (EPA). Some comments were

general in nature and others we re specific to the inte rstate consultation, r easonable progress goal,

long-term strategy, and best ach ievable retrofit tec hnology (BART) sections. Some comments

were also specific to the Holcim Cement-C larksville BART determination and consent

agreement.

COMMENT #1: The EPA recommended that the pl an, including appendices, be reviewed to

assure that it has up-to-date and correct language. As an example, the original plan was

submitted to the EPA in March of 2008 but the pl an language refers to it as the February 2008

submittal on plan pages 69, 70 and 71. Another ex ample is repetitively listing the BASF facility

twice in one sentence on page 58. In addi tion, the plan mentions documents as being

incorporated into an appendix, but the information is not actually in the named appendix in all

cases (e.g. Missouri’s letter to Doe Run- Glover regarding operating permits).

RESPONSE AND EXPLANATION OF CHANGE: In response to these comments, the plan has

been reviewed and updated to reflect the appropriate information.

COMMENT #2: The EPA requested that the re asonable progress, best available control

technology equivalency to BART, potential to emit permit limitation and all Holcim BART

consent agreement comments to be c onsidered major issue comments.

RESPONSE AND EXPLANATION OF CHANGE: The pl an has been reviewed considering the

areas identified as major issues and changes were made when deemed necessary and feasible to

address these areas.

COMMENT #3: The EPA noted that, since Mi ssouri’s Regional Haze Plan is relying on

emission reductions from sources in other stat es in order to meet the 2018 Uniform Rate of

Progress (URP) goal for Missouri’s Class I areas , Missouri should clearly communicate this

reliance to the other states.

RESPONSE AND EXPLANATION OF CHANGE: As a re sult of this comment, letters will be

sent to the states on which Miss ouri is relying for emission reduc tions to meet the URP. The

letter will reiterate what was concluded during the consultation conference calls regarding

Missouri’s reliance on other states’ emi ssion reductions to meet the URP goal.COMMENT #4: The EPA requested additional explanation of how the four statutory factors

were considered in arriving at the Reasonabl e Progress Goal for both Missouri Class I areas.

RESPONSE AND EXPLANATION OF CHANGE: To a ddress this comment, section 10 of the

plan was rewritten to provide more explanation of the how Missouri achi eved the four factor

analysis requirement.

COMMENT #5: The EPA requested that section 11.4 of the long term strategy chapter have a

reference added to Table 10.1 in order to link it to the reasonable furt her progress chapter.

RESPONSE AND EXPLANATION OF CHANGE: As suggested, a reference to Table 10.1

was added to section 11.4.

COMMENT #6: The EPA commente d that section 11.4.2 should be revised to only list those

programs that Missouri is rely ing on for long term strategy.

RESPONSE AND EXPLANATION OF CHANGE: On ly the programs liste d in section 11.4.1.

are relied upon for Missouri’s long term strategy as stated at th e beginning of section 11.4.2. As

stated in section 11.4.2, the programs listed in se ction 11.4.2. are additional control strategies not

included in the modeling demonstration that may be considered during th e five-year review.

These programs are retained in section 11.4.2. for futu re reference. As a result of this comment,

additional explanatory language has been added to section 11.4 for a dditional clarification.

COMMENT #7: The EPA commented that Appendix I of the plan should be revised to provide

consistency in the type of information provided.

RESPONSE AND EXPLANATION OF CHANGE: As a result of this comment, Appendix I

has been revised so that information provi ded is presented in a consistent format.

COMMENT #8: The EPA commented that the potent ial to emit (PTE) limits referenced in this

appendix as reasons for exempting sources from BART should be included in the plan in a

permanent and enforceable manner.

RESPONSE AND EXPLANATION OF CHANGE: The limits referenced in this comment were

for charcoal kiln facilities that were developed after the kilns were required to comply with 10

CSR 10-6.330, Restriction of Emissions from Batch-T ype Charcoal Kilns. This rule limits each

kiln control system to emission limits of 1.5 pounds per hour of particulate matter and 0.24

pounds per hour of volatile organic compounds; which tr anslates to less than 10 tons per year for

both pollutants. The limits are permanent and enfo rceable because they are in this rule which is

part of the Missouri State Implem entation Plan (SIP) and, therefore, federally enforceable. The

control systems required by implementation of this rule have resulted in dramatically reduced

emissions of all air pollutants from the charcoal kiln industry in Missouri. These reductions have

have also resulted in many of the kiln facilities to be classified as Basic operating permit sources

instead of Part 70 (major) sources. Including th ese permits in the SIP will not bring additional

enforceability to these f acilities due to the ongoing requirement s contained in the charcoal kiln

rule. Therefore, reference to these perm its has been removed from Appendix I.

COMMENT #9: The EPA commented that Appendi x J is missing a copy of the Doe Run-Glover

facility termination le tter that is mentioned in the A ppendix C responses to comments.

RESPONSE AND EXPLANATION OF CHANGE: As a result of this comment, a copy of the

Doe Run-Glover facility termination le tter has been added to Appendix J.COMMENT #10: The EPA commente d that some form of techni cal detail should be provided

regarding the Missouri’s determin ation in Section 9.3 that BACT at Doe Run-Buick is equal to

or better than BART. Also, usi ng this determination in the plan requires that the permit must be

amended to specify and reference the origin of an authority for the emission unit as cited in 40

CFR 70.6(a)(1)(ii).

RESPONSE AND EXPLANATION OF CHANGE: In response to this comment, Section 9.3

has been revised to address the finding for Do e Run-Buick’s BART-eligible unit. Specifically,

more documentation was provided to esta blish the BART finding for this unit.

COMMENT #11: The EPA commente d that the explanation of how Missouri performed a more

robust screening of sources subject to BART sh ould describe how the screening criteria was

applied.

RESPONSE: The approach outlined in the plan does not rely on a particular number of impact

days that the State found signifi cant enough to require further anal ysis at a particular Class I

area. The refined screening approach used is consistent with other modeling outcomes that

evaluate only a particular set of receptors when these receptors are clearly higher and provide the

most conservative outcome for the given emission s set. The methodology utilized to perform the

refined screening approach only removed the Hercules, Upper Buffalo, and Mammoth Cave

Class I areas from consideration for the Noranda source. This was done because the very nearby

Mingo Class I area was obviously impacted the most of any of these areas by the Noranda

BART-eligible sources. The remaining sources that underwent refined screening were evaluated

for the Mingo, Hercules, and Upper Buffalo Cla ss I areas except the sensitivity analyses

conducted for Doe Run Buick at Mingo. This re fined screening approach was determined

primarily based on distance from the relevant Cla ss I areas to each source. No change was made

to the plan as a result of this comment.

COMMENT #12: The EPA commented that addi tional clarifying documentation should be

provided describing how Missouri established both the NOx and SO 2 BART limits for Holcim.

RESPONSE: In the comment, EPA asserts that the NOx control efficiencies used by the

department are questionable. The comment does not provide a true and accurate representation

of the BART finding for NOx as only mid-kiln firing and selective non-catalytic reduction

(SNCR) are mentioned. As discussed in the plan , the department found that mid-kiln firing of

tires at a 12 percent total fuel rate along with the existing low-NOx burners and cement kiln dust

insufflation represent BART. The department al so found that the effective use of SNCR on this

long-wet kiln had significant uncertainty. This pr ovided further evidence that established BART

as mid-kiln firing of tires with a 20 percent reduction in NOx emissions.

EPA claims that the use of wet lime scrubbing at th e facility was cost effective and available for

the facility and implies that th e department should have selected this control as BART for SO 2

. In the plan, the department clearly outlines it s basis for the removal of scrubbing technology as

BART under Section 9.3.8, “The department f ound the overall net cost per ton of cement

produced (~$15/20) was excessive and would have seriously compromised th e Clarksville kiln’s

ability to compete in the cement production mark et.” On page 39130 of the Final Rule for

Regional Haze Regulations and Guidelines for BART Determinations published on July 6, 2005;

EPA states, “...we recognize there may be unus ual circumstances that justify taking intoconsideration the conditions of the plant and the economic effect s of requiring th e use of a given

control technology. These effects would include e ffects on product prices, the market share, and

profitability of the source. We did not intend, for example, that the most stringent control

alternative must always be sele cted in that level would cause a plant to shut down...”. The

statement from the rule characteri zes the exact approach used by the department in this instance.

Further, the current operational s hutdown at the facility supports the use of fuel switching as

SO 2 BART (27 percent reduction) at $3/ton cement produced instead of wet scrubbing at nearly

$20/ton cement produced. No changes were made to the plan as a result of this comment.

COMMENT #13: The EPA noted that the 30-day rolling average language in the Holcim

Cement-Clarksville consent agreement a nd the plan language are not consistent.

RESPONSE: The plan states that the calculation of these averages will include all hours when

the kiln is not operating and those emissions fo r both pollutants will be entered as zero pounds.

The agreement specifies conditions where the ki ln is not operating and continuous emission

monitoring data is not required to be collected (paragraph 20 of the agreement). This condition

was implemented to allow shutdown of the monito ring equipment when the kiln is not operating

for an extended period of time. It follows logi cally that if the kiln is not operating and is

sufficiently cooled there will be no emissions of NOx or SO 2 . In paragraph 22 of the agreement,

Holcim is required to, “...record the hourly CEM data or data supporting lack of kiln operation

to demonstrate compliance with the [emission] limits...”. The intention of this statement is to

allow the use of non-operational, zero emission data as part of the 30-day rolling averages for

compliance with the SO 2 and NOx BART limits. Therefore, th is is consistent with the language

in the plan. No change to the plan was made as a result of this comment.

COMMENT #14: The EPA recommends that the agreement stay in place in the event of a

shutdown, or, if the shutdown-term ination language is retained, th ey recommend clarifying that a

current or subsequent owner or operator may only utilize post-BART c ontrol emissions, if any,

for the purposes of netting.

RESPONSE: In the event of a shutdown, Holcim or any subsequent owner wi ll be subject to the

agreement until a permanent cessation letter is sent to the department and the owner agrees to

terminate all operating and construction permits for the site as outlined in Condition 26(G) of the

consent agreement. Once these conditions are me t, the source does not exist any longer and is

permanently shutdown for the purpose of new s ource review. This would mean that any new

kiln or start-up of the existing kiln would be required to undergo a major source permitting

analysis due to the modificati on requirement of the constructi on permit regulation. Therefore,

the new source would not be allowed to net out of a major review and would be subject to the

requirements of best available c ontrol technology and visibility impairment analysis under the

permitting regulations. The department would on ly allow post-BART control emissions for any

netting of a new source at this site . No change was made to the plan as a result of this comment.
