Approval and Promulgation of Implementation Plans and Operating 
Permits Program; State of Iowa

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: EPA is approving a revision to the Iowa State Implementation 
Plan (SIP) and Operating Permits Program submitted by the state of Iowa 
for the purpose of modifying and clarifying requirements for certain 
types of grain elevators. Specifically, the new rule revises the SIP to 
add special requirements for grain elevators, and the associated 
chapters for definitions and emission standards will be revised 
accordingly. The Iowa Department of Natural Resources (IDNR) is 
requiring that owners or operators of grain elevators apply best 
management

[[Page 49951]]

practices and comply with the fugitive dust standard, as well as 
emission controls specified in required construction permits. These 
strategies will protect the ambient air and minimize the impact of 
emissions from each of the facilities.

DATES: This direct final rule will be effective October 24, 2008, 
without further notice, unless EPA receives adverse comment by 
September 24, 2008. If EPA receives adverse comment, we will publish a 
timely withdrawal of the direct final rule in the Federal Register 
informing the public that the rule will not take effect.

SUPPLEMENTARY INFORMATION: Throughout this document whenever ``we,'' 
``us,'' or ``our'' is used, we mean EPA. This section provides 
additional information by addressing the following questions:

What is a SIP?
What is the Federal approval process for a SIP?
What does Federal approval of a state regulation mean to me?
What is a Part 70 operating permits program?
What is the Federal approval process for the operating permits 
program?
What is being addressed in this document?
Have the requirements for approval of a SIP revision and a Part 70 
revision been met?
What action is EPA taking?

What is a SIP?

    Section 110 of the Clean Air Act (CAA) requires states to develop 
air pollution regulations and control strategies to ensure that state 
air quality meets the national ambient air quality standards 
established by EPA. These ambient standards are established under 
section 109 of the CAA, and they currently address six criteria 
pollutants. These pollutants are: Carbon monoxide, nitrogen dioxide, 
ozone, lead, particulate matter, and sulfur dioxide.
    Each state must submit these regulations and control strategies to 
us for approval and incorporation into the Federally-enforceable SIP.
    Each Federally-approved SIP protects air quality primarily by 
addressing air pollution at its point of origin. These SIPs can be 
extensive, containing state regulations or other enforceable documents 
and supporting information such as emission inventories, monitoring 
networks, and modeling demonstrations.

What is the Federal approval process for a SIP?

    In order for state regulations to be incorporated into the 
Federally-enforceable SIP, states must formally adopt the regulations 
and control strategies consistent with state and Federal requirements. 
This process generally includes a public notice, public hearing, public 
comment period, and a formal adoption by a state-authorized rulemaking 
body.
    Once a state rule, regulation, or control strategy is adopted, the 
state submits it to us for inclusion into the SIP. We must provide 
public notice and seek additional public comment regarding the proposed 
Federal action on the state submission. If adverse comments are 
received, they must be addressed prior to any final Federal action by 
us.
    All state regulations and supporting information approved by EPA 
under section 110 of the CAA are incorporated into the Federally-
approved SIP. Records of such SIP actions are maintained in the Code of 
Federal Regulations (CFR) at title 40, part 52, entitled ``Approval and 
Promulgation of Implementation Plans.'' The actual state regulations 
which are approved are not reproduced in their entirety in the CFR 
outright but are ``incorporated by reference,'' which means that we 
have approved a given state regulation with a specific effective date.

What does Federal approval of a state regulation mean to me?

    Enforcement of the state regulation before and after it is 
incorporated into the Federally-approved SIP is primarily a state 
responsibility. However, after the regulation is Federally approved, we 
are authorized to take enforcement action against violators. Citizens 
are also offered legal recourse to address violations as described in 
section 304 of the CAA.

What is the Part 70 operating permits program?

    The CAA Amendments of 1990 require all states to develop operating 
permits programs that meet certain Federal criteria. In implementing 
this program, the states are to require certain sources of air 
pollution to obtain permits that contain all applicable requirements 
under the CAA. One purpose of the part 70 operating permits program is 
to improve enforcement by issuing each source a single permit that

[[Page 49952]]

consolidates all of the applicable CAA requirements into a Federally-
enforceable document. By consolidating all of the applicable 
requirements for a facility into one document, the source, the public, 
and the permitting authorities can more easily determine what CAA 
requirements apply and how compliance with those requirements is 
determined.
    Sources required to obtain an operating permit under this program 
include ``major'' sources of air pollution and certain other sources 
specified in the CAA or in our implementing regulations. For example, 
all sources regulated under the acid rain program, regardless of size, 
must obtain permits. Examples of major sources include those that emit 
100 tons per year or more of volatile organic compounds, carbon 
monoxide, lead, sulfur dioxide, nitrogen dioxide, or PM<INF>10</INF>; 
those that emit 10 tons per year of any single hazardous air pollutant 
(HAP) (specifically listed under the CAA); or those that emit 25 tons 
per year or more of a combination of HAPs.
    Revisions to the state operating permits program are also subject 
to public notice, comment, and our approval.

What is the Federal approval process for an operating permits program?

    In order for state regulations to be included in the Federally-
enforceable Title V operating permits program, states must formally 
adopt regulations consistent with state and Federal requirements. This 
process generally includes a public notice, public hearing, public 
comment period, and a formal adoption by a state-authorized rulemaking 
body.
    Once a state rule, regulation, or control strategy is adopted, the 
state submits it to us for inclusion into the approved operating 
permits program. We must provide public notice and seek additional 
public comment regarding the proposed Federal action on the state 
submission. If adverse comments are received, they must be addressed 
prior to any final Federal action by us.
    All state regulations and supporting information approved by EPA 
under section 502 of the CAA, including revisions to the state program, 
are included in the Federally-approved operating permits program. 
Records of such actions are maintained in the CFR at Title 40, part 70, 
appendix A, entitled ``Approval Status of State and Local Operating 
Permits Programs.''

What is being addressed in this document?

    This rule revision modifies requirements for certain types of grain 
elevators by adding a new rule to the Iowa Administrative Code (IAC) 
with special requirements for these facilities. The rule amendments 
define each type of facility, and also specify the permitting 
requirements, emissions calculation methodology, emissions reporting 
and record keeping, and best management practices for controlling air 
pollution. A particulate matter (PM) emission standard for bin vents 
located at country grain elevators is described in subrule 23.4(7). 
Affected facilities are also required to comply with the fugitive dust 
standard to further minimize emissions. The deadline for affected 
facilities to comply with the new requirements was March 31, 2008.
    The associated definitions are being revised or added to IAC 567 
Chapters 20 and 22 as follows: Country grain elevator, country grain 
terminal elevator, feed mill equipment, grain, grain processing, grain 
storage elevator, grain terminal elevator, permanent storage capacity 
and potential to emit.
    The new rule added into IAC 567 Chapter 22.10(455B) applies to 
permitting requirements for country grain elevators, country grain 
terminal elevators, grain terminal elevators and feed mill equipment. 
Compliance with the new requirements does not alleviate any affected 
person's duty to comply with any applicable state or Federal 
regulations. In particular, the emission standards set forth in 567 
Chapter 23, including the regulations for grain elevators contained in 
40 CFR Part 60 Subpart DD, as adopted by the state, may apply.
    Also added to IAC 567-22.10(455B) are methods for calculating 
potential to emit (PTE) for PM and PM<INF>10</INF> for the four subject 
facilities: Country grain elevators; country grain terminal elevators; 
grain terminal elevators, and feed mill equipment.
    Grain elevators are classified in four groups as follows: Group 1--
facilities with PTE less than 15 tons per year (tpy); Group 2--
facilities with PTE greater than or equal to 15 tpy and less than or 
equal to 50 tpy; Group 3--facilities with PTE more than 50 tpy and not 
more than 100 tpy, and Group 4--facilities that emit greater than or 
equal to 100 tpy.
    These categories of grain elevators are described below. As 
explained below, EPA has reviewed the rules changes and has determined 
that they do not result in an impermissible relaxation of the SIP under 
CAA Section 110(l).
    An owner or operator of a Group 1 facility is required to provide 
registration with PTE calculations and to retain a record of the 
previous five calendar years of total annual grain handled. The 
calculation of the facility's potential PM<INF>10</INF> is required to 
be submitted to IDNR annually by January 31 for the previous calendar 
year. If additions, removals or modifications to equipment are 
performed, emissions will be calculated prior to any changes and if 
emissions increase to 15 tpy or more, the owner or operator shall 
comply with requirements set forth in Groups 2 to 4 as applicable prior 
to making the additions, removals or modifications. The same procedures 
will apply if the owner or operator changes the facility classification 
or permanent grain storage capacity.
    The owner or operator of a Group 2 facility, in lieu of obtaining 
source-specific air construction permits for each piece of emissions 
equipment, may submit a Group 2 permit application with PTE 
calculations on IDNR-provided forms; and, if qualified, may operate 
under a permit by rule. If one or more construction permits exist, it 
remains in full force and effect and is not invalidated by subsequent 
submittal of a Group 2 permit application pursuant to this rule. 
Restrictions on equipment included in a previously-issued construction 
permit may be incorporated into a Group 2 permit on a case-by-case 
basis by IDNR. Records will be maintained as specified in the Group 2 
permit. If additions, removals, or modifications to equipment are 
performed, emissions changes due to these actions will be calculated 
prior to any changes; and if emissions increase beyond 50 tpy or more, 
the owner or operator must comply with requirements set forth in Groups 
3 or 4 (source categories requiring source-specific permits, as 
discussed below) as applicable, prior to making the additions, removals 
or modifications. As with Group 1, the same procedures will apply if 
the owner or operator changes the facility classification or permanent 
grain storage capacity.
    The owner or operator of a Group 3 facility must obtain the 
required source-specific construction permits as specified under 
existing subrule 22.1(1). Owners or operators of new facilities must 
obtain the required permits prior to construction or reconstruction of 
a facility. Records will be maintained as specified in the Group 3 
permit. If additions, removals or modifications to equipment are 
performed, emissions will be calculated prior to any changes; and, if 
emissions increase to 100 tpy or more, the owner or operator must

[[Page 49953]]

comply with the requirements set forth for Group 4 facilities, as 
applicable, prior to making the additions, removals or modifications. 
The same procedures will apply if the owner or operator changes the 
facility classification or permanent grain storage capacity. If the PTE 
for PM or PM<INF>10</INF> triggers major source permitting, the owner 
or operator must comply with the requirements of 567 Chapter 33 (PSD) 
as applicable. Fugitive emissions as defined in 567-33.3(1) are 
included in the PTE calculation for determining PSD applicability. The 
owner or operator shall keep records of annual grain handled at the 
facility and annual PTE emissions on site for a period of five years.
    The owner or operator of a Group 4 facility is required to obtain 
source-specific construction permits as specified under subrule 22.1(1) 
in the current SIP. The owner or operator of a new facility shall 
obtain the required permits prior to construction or reconstruction of 
a facility. Records will be maintained as specified in the Group 4 
permit. If the PTE for PM or PM<INF>10</INF> triggers major source 
permitting, the owner or operator must comply with the requirements of 
567 Chapter 33 (PSD) as applicable. Fugitive emissions as defined in 
567-33.3(1) are included in the PTE calculation for determining PSD 
applicability. The owner or operator shall keep records of annual grain 
handled at the facility and annual PTE emissions on site for a period 
of five years. The owner or operator of a Group 4 facility shall apply 
for an operating permit for the facility if the annual PTE for PM or 
PM<INF>10</INF> is equal to or greater than 100 tpy as specified in 
rules 567-22.100(455B) through 567-22.300(455B), which are part of the 
currently-approved Title V program. Fugitive emissions in the 
calculations will be included if the PTE for PM<INF>10</INF> is greater 
than 100 tpy.
    The rule revision means that Group 1 sources (sources emitting less 
than 15 tpy of PM or PM<INF>10</INF>) will not be required to obtain 
source-specific permits if they adequately demonstrate that emissions 
are less than that threshold. The state has submitted a demonstration 
that grain elevators of this size would not adversely impact air 
quality. EPA believes the state has shown that sources of this size 
would not be expected to adversely impact air quality.
    Group 2 sources (sources emitting between 15 and 50 tpy) are not 
required to obtain source-specific permits if they operate in 
accordance with the requirements of the rule (for example, requiring 
implementation of best management practices for controlling particulate 
matter emissions). These sources obtain standardized permits. The state 
retains the ability to require source-specific air quality analyses 
from these sources if the Group 2 application, or other information, 
indicates that a particular source might adversely impact air quality. 
EPA concludes there are sufficient safeguards in the rule to ensure 
that Group 2 sources will not adversely impact air quality.
    The rule requires that Groups 3 and 4 sources obtain traditional 
source-specific permits. Therefore, there is no substantive change from 
the current SIP for sources in these groups.
    As feed mill equipment does not fall under the grain elevator 
classifications, a separate section of the new rule sets forth the 
requirements with regard to permitting, emissions inventory, operating 
permits, and prevention of significant deterioration applicability. 
These requirements generally entail no change from the current SIP.
    EPA is also approving a revision to Chapter 23 of the IAC with 
regard to grain handling and processing plants. The revision states 
that the owner or operator of equipment at a permanent installation 
shall not cause, allow or permit the particulate matter discharged to 
the atmosphere to exceed 0.1 grain per dry standard cubic foot of 
exhaust gas with the following exception: Particulate matter discharged 
to the atmosphere from a grain bin vent at a country grain elevator 
shall not exceed 1.0 grain per dry standard cubic foot of exhaust gas; 
particulate matter discharged from a grain bin vent at a country grain 
terminal elevator or a grain terminal elevator constructed before March 
31, 2008, shall not exceed 1.0 grain per dry standard cubic foot of 
exhaust gas, and particulate matter discharged from a grain bin vent at 
a country grain terminal elevator or a grain terminal elevator 
constructed after March 31, 2008, shall not exceed 0.1 grain per dry 
standard cubic foot of exhaust gas. IDNR provided an analysis of PM 
emissions which showed that PM emissions would be less than 5 tpy at a 
facility with 35 million bushels per year throughput rate. The 
throughput is on the upper end of the throughput range for the majority 
of the grain elevators that will be affected by the rules; and based on 
the analysis of PM emissions, the revision would not be expected to 
adversely impact air quality. EPA has determined that the state's 
analysis of this rule change meets the requirements of CAA section 
110(l).

Have the requirements for approval of a SIP revision and a Part 70 
revision been met?

    The state submittal has met the public notice requirements for SIP 
submissions in accordance with 40 CFR 51.102. The submittal also 
satisfied the completeness criteria of 40 CFR Part 51, appendix V. In 
addition, as explained above and in more detail in the technical 
support document which is part of this docket, these revisions meet the 
substantive SIP requirements of the CAA, including section 110 and 
implementing regulations. These revisions are minor clarifications, 
updates, and corrections which do not affect the stringency of existing 
requirements. These revisions are also consistent with applicable EPA 
requirements in Title V of the CAA and 40 CFR Part 70.

What action is EPA taking?

    EPA is approving the request to amend the Iowa SIP and Operating 
Permits Program to approve the modification of requirements for certain 
types of grain elevators. These modifications will not adversely affect 
the air quality in the state of Iowa and will not relax the SIP. The 
state provided adequate justification to this effect. We are processing 
this action as a direct final action because the revisions make routine 
changes to the existing rules which are noncontroversial. Therefore, we 
do not anticipate any adverse comments. Please note that if EPA 
receives adverse comment on part of this rule and if that part can be 
severed from the remainder of the rule, EPA may adopt as final those 
parts of the rule that are not the subject of an adverse comment.

Statutory and Executive Order Reviews

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
action is not a ``significant regulatory action'' and therefore is not 
subject to review by the Office of Management and Budget. For this 
reason, this action is also not subject to Executive Order 13211, 
``Actions Concerning Regulations That Significantly Affect Energy 
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action 
merely approves 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

[[Page 49954]]

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 (Pub. L. 104-4).
    This rule also does not have tribal implications because it will 
not have a substantial direct effect on one or more Indian tribes, on 
the relationship between the Federal Government and Indian tribes, or 
on the distribution of power and responsibilities between the Federal 
Government and Indian tribes, as specified by Executive Order 13175 (65 
FR 67249, November 9, 2000). This action also does not have Federalism 
implications because it does 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). This action merely approves a state rule 
implementing a Federal standard, and does not alter the relationship or 
the distribution of power and responsibilities established in the CAA. 
This rule also is not subject to Executive Order 13045, ``Protection of 
Children from Environmental Health Risks and Safety Risks'' (62 FR 
19885, April 23, 1997), because it approves a state rule implementing a 
Federal standard.
    In reviewing SIP and Title V submissions, EPA's role is to approve 
state choices, provided that they meet the criteria of the CAA. 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 CAA. 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. This rule does not impose an 
information collection burden under the provisions of the Paperwork 
Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this rule and other 
required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by October 24, 2008. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of this rule for the purposes of judicial review nor does 
it extend the time within which a petition for judicial review may be 
filed, and shall not postpone the effectiveness of such rule or action. 
This action may not be challenged later in proceedings to enforce its 
requirements. (See section 307(b)(2).)
