[EPA-R07-OAR-2019-0708; FRL-8711-01-R7]


Air Plan Approval; Iowa; Polk County; State Implementation Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve revisions to the Iowa State Implementation Plan (SIP) to 
include recent changes to the Polk County Board of Health Rules and 
Regulations in addition to revisions from past submittals. The proposed 
revisions update definitions and references to the effective dates of 
Federal rules approved into the State's SIP, prohibit burning of 
demolished buildings, update references to methods and procedures for 
performance test/stack test and continuous monitoring systems, and 
revise permitting exemptions. These proposed revisions will not 
adversely impact air quality and will ensure consistency between the 
State and Federally approved rulemakings.

II. What is being addressed in this document?

    The EPA is proposing to approve a submission from the State of Iowa 
to revise its SIP to incorporate recent updates to Chapter 10 of Polk 
County's Code of Regulation pertaining to air quality. The Clean Air 
Act (CAA) allows authorized States to delegate portions of the Act's 
implementation and enforcement to local governments such

[[Page 40393]]

as Polk County. The proposed revisions to the Iowa SIP incorporate Polk 
County's updated definitions and references to the effective dates of 
Federal rules approved into the State's SIP, update references to 
methods and procedures for performance test/stack test and continuous 
monitoring systems, prohibit burning of demolished buildings, and 
revise permitting exemptions. The proposed revisions to the Iowa SIP 
also include changes to Polk County's public notice and participation 
requirements to allow permit modifications to be published online 
rather than in area newspapers which is consistent with recent 
revisions to Iowa's SIP (83 FR 191, October 2, 2018).
    The EPA is not acting on portions of Polk County Chapter V that 
amend Standards for Marijuana Production and Marijuana Processing 
(section 5-21), Permits for New and Existing Stationary Sources, and 
Chapter 10-59, Permit Fees, that pertain to Prevention of Significant 
Deterioration (PSD) regulations because Iowa has not delegated the PSD 
program authority to Polk County.
    The EPA is also proposing to approve minor changes to the text of 
various ordinances that were previously submitted to the EPA, but were 
inadvertently omitted from previous actions. These revisions were 
contained in submittals dated December 3, 2007, September 1, 2009, 
September 19, 2011, April 15, 2014, and November 25, 2015.

III. What SIP revisions are being proposed by the EPA?

    The EPA is proposing approval of the revisions to the Iowa SIP to 
incorporate revisions to Chapter V of the Polk County Board of Health 
Rules and Regulations listed below. A Technical Support Document (TSD) 
with a detailed description of the proposed revisions and the rationale 
for approval has been prepared by the EPA and is provided in the docket 
for this proposed action.
    Article I, In General. The proposed rule changes update the 
references to effective dates and definitions. The rule changes are 
administrative updates that do not negatively impact air quality and 
ensure greater consistency with the Iowa regulations.
    Article III, Incineration and Open Burning. Polk County amended 
this article to add a prohibition against burning demolished buildings. 
The addition of the prohibition on burning of demolished buildings will 
lead to reduced particulates and hazardous air pollutants (HAPs) thus 
improving air quality.
    Article VI, Emission Of Air Contaminants From Industrial Processes. 
Section 5-16 is being amended to include a general provision 
referencing paragraph (n) which applies to New Source Performance 
Standards (NSPS). NSPS is delegated by Iowa to Polk County but not SIP-
approved by the EPA. The EPA proposes to approve the general provision 
because it pertains to a delegated authority.
    Article VII, Performance Test For Stack Emission Test. In section 
5-18, paragraph (a)(2) the title and references to ``stack sampling'' 
are being revised to read ``performance test (stack test)'' and 
``department'' is being changed to read ``local program.'' These minor 
changes in wording do not impact air quality. References to performance 
test methods and specifications and quality assurance procedures for 
performance evaluations of continuous monitoring systems are being 
updated to be consistent with the currently approved references in Iowa 
code. Thus, for consistency, the EPA is proposing to approve these 
updates.
    Article X, Permits, Division 1, Construction Permits. Section 5-28, 
Construction Permit Required, is being amended to add ``Air Quality 
Division (AQD)'' to the title. Subparagraphs (1) through (4) of 
paragraph (c) are not highlighted in Iowa's SIP revision request as new 
text. After consulting with Iowa, the State submitted an Addendum dated 
July 21, 2020, to request EPA approval of paragraphs (1) though (4) of 
section 5-28 into the SIP, and stated that section 5-28 has been 
submitted to EPA for approval in the past. The text of these paragraphs 
is substantively similar to that of Iowa 22.1 (455B) and 22.3 (b) which 
EPA has approved into Iowa's SIP; thus, the EPA recommends approval of 
Paragraphs (a) through (c), including subparagraphs (1) through (4) of 
paragraph (c), to ensure consistency between Polk County's and Iowa's 
air permitting regulations.
    The title of article X, section 5-29, is being revised to add that 
the application is for a ``construction'' permit and the acronym 
``AQD.'' The new title now reads ``Application for a Construction 
Permit (AQD).'' Also, this section is being revised to add a paragraph 
title, ``construction permit applications,'' to revise ``health 
officer'' to now read ``local program,'' to eliminate that the 
applications must be submitted ``in duplicate,'' and to add 
``applications'' to the list of items to be submitted by entities 
seeking a construction permit. The EPA proposes to approve these 
changes into the Iowa SIP because they clarify the construction 
permitting process and reduce the number of hard copies that need to be 
submitted.
    Polk County has added the acronym ``AQD'' representing the Air 
Quality Division to title X, sections 5-30, Processing of Applications 
for Construction Permits, section 5-31, Issuance of Construction 
Permits, and section 5-32, Denial of Permit. These additions represent 
minor clarifications. As such, the EPA proposes to approve them.
    The acronym ``AQD'' has also been added to title X, section 5-33, 
Exemptions from Permit Requirements. In item (50), Production Welding, 
``stationary source'' is replacing ``facility.'' Further, the equations 
used to calculate the exemption in item (50) are being revised. The 
calculations make item (50) more stringent than calculations set forth 
in the welding exemption in the EPA-approved Iowa SIP, section 
22.1(2)(ff)(1).
    Item (62) has been added to section 5-33. Item (62) exempts from 
construction permitting non-road diesel engines used for periodic 
testing and maintenance of natural gas compressor engines. The 
exemption is consistent with EPA-approved construction permitting 
requirements in Chapter 22.1(2) ``oo'' of the Iowa code. The EPA 
proposes to approve item (62) into the Iowa SIP as it makes Polk 
County's authorities consistent with Iowa's.
    Article X, Permits, Division 2, Operating Permits. ``Annual 
Operating'' is being added to the title of section 5-37 to clarify the 
type of permit to which the section pertains. The acronym ``AQD'' is 
being added as well. The reference to ``department'' is being changed 
to ``Local Program.'' Also, this section is being updated to be 
consistent with Iowa code regarding public notice requirements. The 
State made revisions that address public participation requirements for 
its PSD permitting program to reflect updates to the Federal 
regulations, at 40 CFR part 51, subpart I, published October 18, 2016. 
The revision removes the requirements for advertisement in a newspaper 
of general circulation in each region in which the proposed source will 
be constructed and provides for posting of the public comment period on 
a website identified by the State. The language and intent of the 
revisions to the Polk County rules and regulations are consistent with 
the Federal regulations and the EPA-approved Iowa SIP. Thus, the EPA is 
proposing to approve these Polk County revisions into the Iowa SIP.
    The title for section 5-39 is being revised to clarify that the 
listed exemptions are for ``Annual Operating'' Permits. Revisions to 
item (43) update the language from ``facility'' to ``stationary 
source(s)'' and correct the

[[Page 40394]]

equation for exemption from permitting for welding activities to agree 
with that in Iowa code. The EPA is proposing to approve these revisions 
because they clarify the permit exemptions.
    Items (56), Equipment related to research and development 
activities at a stationary source, (57), Exemptions for non-road diesel 
combustion engines, and item (58), fuel burning equipment for indirect 
heating or cooling with a capacity less than one million Btu per hour 
input when burning No. 1 or No. 2 fuel oil, are consistent with 
previously approved exemptions in section 22.1(b) of the Iowa SIP. In 
paragraphs (57) and (58), Polk County has elected to be more stringent 
in its regulations than the EPA-approved Iowa code for similar 
operations. The EPA is proposing to approve items (56), (57) and (58) 
into the Iowa SIP.
    Section 5-39, paragraph (b) was not highlighted as new language in 
Iowa's SIP revision request; however, following discussions with Iowa, 
the state indicated that this paragraph had been requested for approval 
in a previous submittal, and requested approval of this paragraph in 
its July 21, 2020, Addendum. This paragraph discusses exemptions from 
permitting for smaller liquified or natural gas fired heaters, 
residential wood or pellet heaters, cook stoves and fireplace, as well 
as jet engines, marine engines and locomotives. This paragraph is 
consistent with Iowa code section 22.1 which is EPA-approved; thus, the 
EPA is proposing to approve the same Polk County exemptions.
    Revisions to sections 5-40, 5-42, 5-43 and 5-44 are clarifications 
that the permits discussed are ``Annual Operating'' permits issued by 
AQD. The EPA is proposing to approve these minor editorial changes, as 
there is no impact to air quality.

IV. Have the requirements for approval of a SIP been met?

    The submittals met the public notice requirements for SIP 
submissions in accordance with 40 CFR 51.102. The submission also 
satisfies the completeness criteria of 40 CFR part 51, appendix V. In 
addition, these proposed revisions meet the substantive SIP 
requirements of the CAA, including section 110 and implementing 
regulations. These proposed revisions are also consistent with 
applicable EPA requirements of title V of the CAA and 40 CFR part 70.

V. What actions are proposed?

    The EPA is proposing to approve revisions to the Iowa SIP to 
incorporate the revisions to chapter 5, Air Pollution, of the Polk 
County Board of Health Rules and Regulations. The proposed revisions 
clarify rules, make revisions and corrections, and rescind portions of 
rules no longer relevant to the air program. The EPA has determined 
that approval of these proposed revisions will not adversely impact air 
quality and will ensure consistency between the local, State and 
federally-approved rules, and will ensure Federal enforceability of the 
State's revised air program rules.

VI. Incorporation by Reference

    In this document, the EPA is proposing to include regulatory text 
in an EPA final rule that includes incorporation by reference. In 
accordance with requirements of 1 CFR 51.5, the EPA is proposing to 
incorporate by reference the Iowa Regulations described in the proposed 
amendments to 40 CFR 52 set forth below. The EPA has made, and will 
continue to make, these materials generally available through 
www.regulations.gov and at the EPA Region 7 Office (please contact the 
person identified in the FOR FURTHER INFORMATION CONTACT section of 
this preamble for more information).

VII. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, the EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely approves state law as meeting Federal requirements and 
does not impose additional requirements beyond those imposed by state 
law. For that reason, this action:
     Is not a significant regulatory action subject to review 
by the Office of Management and Budget under Executive Orders 12866 (58 
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
     Is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because SIP approvals are exempted under 
Executive Order 12866.
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     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);
     Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    The SIP is not approved to apply on any Indian reservation land or 
in any other area where the EPA or an Indian tribe has demonstrated 
that a tribe has jurisdiction. In those areas of Indian country, the 
proposed rule does not have tribal implications and will not impose 
substantial direct costs on tribal governments or preempt tribal law as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
