21908 Federal Register / Vol. 77, No. 71 / Thursday, April 12, 2012 / Proposed Rules 

electricity generating units (EGUs) 

designated as Units 1, 2, and 3 at the 

Reid Gardner Generating Station in 

Clark County, Nevada. 

(1) Definitions. Terms not defined 

below shall have the meaning given to 

them in the Clean Air Act or EPA’s 

regulations implementing the Clean Air 

Act. For purposes of this section: 

Ammonia injection shall include any 

of the following: anhydrous ammonia, 

aqueous ammonia or urea injection. 

Combustion controls shall mean new 

low NOX burners, new overfire air, and/ 

or rotating overfire air. 

Continuous emission monitoring 

system or CEMS means the equipment 

required by 40 CFR Part 75 to determine 

compliance with this section. 

NOX means nitrogen oxides expressed 

as nitrogen dioxide (NO2). 

Owner/operator means any person 

who owns or who operates, controls, or 

supervises an EGU identified in 

paragraph (e) of this section. 

Unit means any of the EGUs identified 

in paragraph (e) of this section. 

Unit-wide means all of the EGUs 

identified in paragraph (e) of this 

section. 

(2) Emission limitations—The NOX

limit, expressed as nitrogen dioxide, for 

Units 1, 2, and 3 shall be 0.20 lb/MMBtu 

based on a unit-wide heat input 

weighted average determined over a 

rolling 30-calendar day period. NO2

emissions for each calendar day shall be 

determined by summing the hourly 

emissions measured in pounds of NO2

for all operating units. Heat input for 

each calendar day shall be determined 

by adding together all hourly heat 

inputs, in millions of BTU, for all 

operating units. Each day the thirty-day 

rolling average shall be determined by 

adding together that day and the 

preceding 29 days’ pounds of NO2 and 

dividing that total pounds of NO2 by the 

sum of the heat input during the same 

30-day period. The results shall be the 

30-calendar day rolling pound per 

million BTU emissions of NO2.

(3) Compliance date. The owners and 

operators subject to this section shall 

comply with the emissions limitations 

and other requirements of this section 

within 5 years from promulgation of this 

paragraph and thereafter. 

(4) Testing and Monitoring. (i) The 

owner or operator shall use 40 CFR Part 

75 monitors and meet the requirements 

found in 40 CFR Part 75. In addition to 

these requirements, relative accuracy 

test audits shall be performed for both 

the NO2 pounds per hour measurement 

and the hourly heat input measurement, 

and shall have relative accuracies of less 

than 20%. This testing shall be 

evaluated each time the 40 CFR Part 75 

monitors undergo relative accuracy 

testing. Compliance with the emission 

limit for NO2 shall be determined by 

using data that is quality assured and 

considered valid under 40 CFR Part 75, 

and which meets the relative accuracy 

of this paragraph. 

(ii) If a valid NOX pounds per hour or 

heat input is not available for any hour 

for a unit, that heat input and NOX

pounds per hour shall not be used in the 

calculation of the unit-wide rolling 30- 

calendar day average. Each Unit shall 

obtain at least 90% valid hours of data 

over each calendar quarter. 40 CFR Part 

60 Appendix A Reference Methods may 

be used to supplement the Part 75 

monitoring. 

(iii) Upon the effective date of the 

unit-wide NOX limit, the owner or 

operator shall have installed CEMS 

software that meets with the 

requirements of this section for 

measuring NO2 pounds per hour and 

calculating the unit-wide 30-calendar 

day rolling average as required in 

paragraph (e)(2) of this section. 

(iv) Upon the completion of 

installation of ammonia injection on any 

of the three units, the owner or operator 

shall install, and thereafter maintain 

and operate, instrumentation to 

continuously monitor and record levels 

of ammonia consumption for that unit. 

(5) Notifications. (i) The owner or 

operator shall notify EPA within two 

weeks after completion of installation of 

combustion controls or ammonia 

injection on any of the units subject to 

this section. 

(ii) The owner or operator shall also 

notify EPA of initial start-up of any 

equipment for which notification was 

given in paragraph (e)(5)(i). 

(6) Equipment Operations. After 

completion of installation of ammonia 

injection on any of the three units, the 

owner or operator shall inject sufficient 

ammonia to minimize the NOX

emissions from that unit while 

preventing excessive ammonia 

emissions. 

(7) Recordkeeping. The owner or 

operator shall maintain the following 

records for at least five years: 

(i) For each unit, CEMS data 

measuring NOX in lb/hr, heat input rate 

per hour, the daily calculation of the 

unit-wide 30-calendar day rolling lb 

NO2/MMbtu emission rate as required 

in paragraph (e)(2) of this section. 

(ii) Records of the relative accuracy 

test for NOX lb/hr measurement and 

hourly heat input 

(iii) Records of ammonia consumption 

for each unit, as recorded by the 

instrumentation required in paragraph 

(e)(4)(iv) of this section. 

(8) Reporting. Reports and 

notifications shall be submitted to the 

Director of Enforcement Division, U.S. 

EPA Region IX, at 75 Hawthorne Street, 

San Francisco, CA 94105. Within 30 

days of the end of each calendar quarter 

after the effective date of this section, 

the owner or operator shall submit a 

report that lists the unit-wide 30- 

calendar day rolling lb NO2/MMBtu 

emission rate for each day. Included in 

this report shall be the results of any 

relative accuracy test audit performed 

during the calendar quarter. 

(9) Enforcement. Notwithstanding any 

other provision in this implementation 

plan, any credible evidence or 

information relevant as to whether the 

unit would have been in compliance 

with applicable requirements if the 

appropriate performance or compliance 

test had been performed, can be used to 

establish whether or not the owner or 

operator has violated or is in violation 

of any standard or applicable emission 

limit in the plan.

SUPPLEMENTARY INFORMATION: 

Throughout this document, whenever 

‘‘we,’’ ‘‘us,’’ or ‘‘our’’ is used, we mean 

EPA. On April 14, 2009, PADEP 

submitted revisions to its State 

Implementation Plan (SIP). The 

proposed revisions consist of 

amendments to the plan approval 

requirements for the construction, 

modification, reactivation, and 

operation of sources. 

Table of Contents

II. Summary of SIP Revision 

III. Proposed Action 

IV. Statutory and Executive Order Reviews 

I. Background 

Generally speaking, anyone 

constructing or operating a source in 

Pennsylvania that emits pollutants into 

the air must comply with the general 

requirement to obtain a ‘‘plan approval’’ 

prior to construction as outlined in 25 

Pa. Code 127, Subchapters A and B. 

These subchapters are generally 

considered the state’s minor New 

Source Review (NSR) program covering 

minor sources as well as minor changes 

at major sources. Major sources are 

subject to the additional requirements of 

subchapters D Prevention Significant 

Deterioration (PSD) and E 

(nonattainment NSR). Subchapter E also 

includes additional provisions relating 

to minor changes at major sources for 

ozone precursors Nitrogen Oxides and 

Volatile Organic Compounds (NOx and 

VOCs). A plan approval is a permit that 

authorizes construction, installation, or 

modification of any air pollution source. 

In evaluating the plan approval 

application, PADEP checks to see that 

both the operation of the source and the 

control equipment installed to reduce 

air pollution meet the applicable 

technical and engineering requirements. 

The public is given an opportunity to 

comment on the plan approval 

application. In addition to being a 

permit to construct, the plan approval 

provides temporary authorization for 

the source to operate to assure that the 

equipment functions properly. This 

temporary authorization is known as the 

‘‘shakedown’’ period. 

The plan approval regulations that are 

the subject of this proposed action are 

codified at 25 Pa. Code 127, Subchapter 

B (relating to general requirements for 

all plan approvals). EPA last took action 

on these provisions on July 30, 1996. 

Pennsylvania adopted the amendments 

being proposed in this action, and 

published notice of final rulemaking in 

the Pennsylvania Bulletin on May 24, 

2008. The primary purpose of the 

amendments is to streamline the 

permitting process by eliminating some 

of the administrative burden and costs 

associated with processing minor 

permitting actions, while preserving the 

right of the public to review and 

comment on those proposed actions. 

The proposed amendments generally 

affect five regulations: Section 127.12b, 

pertaining to ‘‘shakedown’’ periods for 

new or modified sources; section 

127.12d, pertaining to completeness 

determinations; sections 127.44 and 

127.45, pertaining to public notice 

requirements; and section 127.48, 

pertaining to conferences and hearings. 

The specific revisions are discussed in 

detail below. 

II. Summary of SIP Revision 

A. 25 Pa. Code 127.12b: Plan Approval 

Terms and Conditions 

Section 127.12b(d), as approved by 

EPA on July 30, 1996, authorizes a 

temporary ‘‘shakedown’’ period for new 

and modified sources and air cleaning 

equipment for a period of 180 days 

pending issuance of a state operating 

permit or a Title V permit, ‘‘* * * to 

permit the evaluation of the air 

contamination aspects of the source’’ 

(see section 127.12b(d)). The regulation 

as currently approved in Pennsylvania’s 

SIP also allows for limited extensions of 

this period, with each extension limited 

to 120 days. The proposed revision 

increases the permissible duration of the 

extensions to 180 days. 

B. 25 Pa. Code 127.12d: Completeness 

Determination 

The proposed revisions incorporate 

new requirements into the Pennsylvania 

SIP that outline PADEP’s obligations 

with respect to determining whether an 

applicant has submitted an 

administratively complete application, 

and notifying the applicant of that 

decision. These requirements are 

codified at section 127.12d(a) thru (c). 

Section 127.12d(a) requires PADEP to 

make a completeness determination and 

provide notice to the applicant within 

30 days of receipt of the application. 

Section 127.12d(b) establishes 

guidelines for what constitutes an 

administratively complete application.

21910 Federal Register / Vol. 77, No. 71 / Thursday, April 12, 2012 / Proposed Rules 

In the event an application is deemed to 

be incomplete, section 127.12d(c) 

requires PADEP to notify the applicant 

of the specific deficiency, and to return 

the application and fees to the applicant 

if the requested information is not 

submitted within ten (10) working days 

of being notified by PADEP that the 

application is incomplete. These 

regulations as proposed by PADEP are 

consistent with CAA requirements, and 

are in fact more prescriptive than their 

Federal counterparts at 40 CFR 

51.166(q)(1). 

C. 25 Pa. Code 127.44: Public Notice 

and 25 Pa. Code 127.45: Contents of 

Notice 

The public notice requirements of 

section 127.44 as currently approved in 

the Pennsylvania SIP make no 

distinction between major and minor 

permitting actions—the requirements 

are the same. Pennsylvania adopted the 

proposed revisions to the public notice 

requirements of section 127.44 (and 

127.45, below) in an effort to streamline 

the process for minor permitting actions 

and allow PADEP to focus its limited 

resources on major permitting actions. 

In the current SIP, section 127.44 

sections (a)(1) thru (6) list the types of 

plan approvals for which the public 

notice requirements apply. These 

include section (a)(5): ‘‘Other sources 

required to obtain plan approval,’’ 

which has the effect of applying the 

notice requirements to all plan approval 

actions equally. Pennsylvania has a 

robust minor New Source Review (NSR) 

program. Very few sources escape the 

requirement to obtain a plan approval, 

and every plan approval is subject to 

public notice requirements. Prior to 

these revisions, significant time and 

resources were being spent on relatively 

minor permitting actions. The proposed 

revisions involve the bifurcation of the 

notice requirements into a new section 

127.44(a) which applies to minor 

actions, and a new section 127.44(b) 

which applies to major actions as well 

as any action for which PADEP 

determines that significant public 

interest exists. The remaining 

unchanged sections were re-ordered 

sequentially to allow for the bifurcation. 

Pursuant to the proposed 

amendments, under the revised section 

127.44(a) PADEP will publish a ‘‘notice 

of receipt and intent to issue’’ in the Pa. 

Bulletin for each plan approval 

application relating to a minor 

permitting action. PADEP has, as a 

policy, generally published two notices 

for all plan approval actions: one upon 

receipt of an application, and one of 

intent to issue a proposed plan 

approval. Under the proposed revisions, 

proposed plan approval actions that are 

subject to section 127.44(a) will be 

issued at the end of the public comment 

period without further notice, unless 

significant public comments are 

received. The notice requirements for 

major actions, now at section 127.44(b), 

were not substantively amended. We 

read the requirements of section 

127.44(f) to apply to all plan approvals 

that are subject to section 127.44. These 

include the requirement that the 

application materials be made available 

for review in the region affected by the 

project, and that a 30-day public 

comment period be established 

(127.44(f)(1) and (f)(2) respectively). 

In the proposed revisions, section 

127.45 was similarly bifurcated to 

incorporate separate requirements for 

minor and major actions. As with the 

notice requirements of section 127.44, 

the content requirements of section 

127.45 for permitting actions considered 

by PADEP to be major, (now at 

127.45(b)), were not substantively 

modified. For minor actions, section 

127.45(a) outlines what must be 

included in each ‘‘notice of receipt and 

intent to issue.’’ These requirements 

include: the name and address of the 

applicant and the location of the source, 

a brief discussion of the proposed action 

including a description of the source, 

the control technology, the conditions 

being placed in the permit, and the type 

and quantity of air contaminants being 

emitted, as well as a point of contact at 

PADEP, and the statement that a person 

may oppose the proposed plan approval 

by filing a written protest with the 

appropriate regional office (see 

proposed section 127.45(a)). The 

requirements for minor permitting 

actions under this section do not vary 

significantly from the requirements for 

major actions. The primary differences 

are that section 127.45(b) requires a 

description of increment consumption 

(where applicable), and a description of 

the procedures for reaching a final 

decision on the proposed plan approval, 

including the end date for receipt of 

written protests, procedures for 

requesting a hearing, and other 

procedures for public involvement in 

the final decision (see proposed section 

127.45(b)(6)). The result of the proposed 

revisions to sections 127.44 and 127.45 

is that for minor permitting actions, 

public notice of the proposed action 

will be less detailed than for major 

actions, will be provided once, and only 

in the Pa. Bulletin (which publishes 

online and in print). 

The Federal requirements with regard 

to public availability of information are 

codified at 40 CFR 51.161. Specifically, 

40 CFR 51.161(a) requires that ‘‘[t]he 

public information must include the 

agency’s analysis of the effect of 

construction or modification on ambient 

air quality, including the agency’s 

proposed approval or disapproval.’’ EPA 

believes that to some extent, the intent 

of section 51.161(a) was met in sections 

127.45(a)(3) and (4) of Pennsylvania’s 

proposed SIP revision, which discuss 

the content of the public notice. These 

sections require a description of the 

proposed construction or modification, 

the control technology being installed, 

the conditions in the proposed permit 

(with reference to applicable federal 

requirements), and the type and 

quantity of air contaminants being 

emitted. Nevertheless, the agency 

analysis required by 40 CFR 51.161(a) is 

not explicitly required in the proposed 

SIP revision, nor do the regulations of 

sections 127.44 and 127.45 require that 

the agency’s analysis be made available 

for public inspection in at least one 

location, in accordance with 40 CFR 

51.161(b)(1). Section 127.44(f)(1) 

requires only that the application be 

made available. Therefore, EPA is 

proposing to grant limited approval to 

PADEP’s proposed revision. To receive 

full approval, PADEP must adopt the 

explicit requirement that the agency’s 

analysis be included in the information 

provided to the public for comment 

pursuant to 40 CFR 51.161(a), as well as 

the requirement that the analysis be 

made available for public inspection 

pursuant to 40 CFR 51.161(b)(1), and 

submit those changes to EPA as a formal 

SIP revision. 

D. 25 Pa. Code 127.48: Conferences and 

Hearings 

The regulations at section 127.48 

contain the requirements regarding 

public hearings or fact finding 

conferences on proposed plan 

approvals. The PADEP may, at its 

discretion, hold such a hearing when it 

is deemed necessary due to sufficient 

public impact or interest. The proposed 

amendments to section 127.48(b) 

include some clarifying language 

regarding hearing notices. More 

substantively, the amendments include 

the requirement to publish notice 

‘‘* * * in a newspaper of general 

circulation in the county in which the 

source is to be located * * *’’. The 

current SIP only requires that the notice 

be published in the Pa. Bulletin or a 

newspaper. The regulations as amended 

in the proposed SIP revision require 

both, and as such represent a 

strengthening of the SIP. 

III. Proposed Action 

EPA’s review of this material 

indicates that with the one noted 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

Federal Register / Vol. 77, No. 71 / Thursday, April 12, 2012 / Proposed Rules 21911 

exception, the proposed revisions to 25 

Pa. Code 127, Subchapter B meet or 

exceed Federal requirements. EPA is 

proposing to grant limited approval to 

the Pennsylvania SIP revision, which 

was submitted on April 14, 2009. EPA 

is soliciting public comments on the 

issues discussed in this document. 

These comments will be considered 

before taking final action. 

IV. Statutory and Executive Order 

Reviews 

Under the CAA, the Administrator is 

required to approve a SIP submission 

that complies with the provisions of the 

CAA and applicable Federal regulations. 

42 U.S.C. 7410(k); 40 CFR 52.02(a). 

Thus, in reviewing SIP submissions, 

EPA’s role is to approve state choices, 

provided that they meet the criteria of 

the CAA. Accordingly, this action 

merely proposes to approve state law as 

meeting Federal requirements and does 

not impose additional requirements 

beyond those imposed by state law. For 

that reason, this proposed action: 

• Is not a ‘‘significant regulatory 

action’’ subject to review by the Office 

of Management and Budget under 

Executive Order 12866 (58 FR 51735, 

October 4, 1993); 

• 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). 

In addition, this proposed action 

regarding streamlining amendments to 

Pennsylvania’s plan approval process 

does not have tribal implications as 

specified by Executive Order 13175 (65 

FR 67249, November 9, 2000), because 

the SIP is not approved to apply in 

Indian country located in the state, and 

EPA notes that it will not impose 

substantial direct costs on tribal 

governments or preempt tribal law.
