Approval and Promulgation of Air 

Quality Implementation Plans; 

Mississippi; Update to Materials 

Incorporated by Reference 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule; administrative 

change. 

SUMMARY: EPA is publishing this action 

to provide the public with notice of the 

update to the Mississippi State 

Implementation Plan (SIP) compilation. 

In particular, materials submitted by 

Mississippi that are incorporated by 

reference (IBR) into the Mississippi SIP 

are being updated to reflect EPAapproved revisions to Mississippi’s SIP 

that have occurred since the last update. 

In this action, EPA is also notifying the 

public of the correction of certain 

typographical errors. 

DATES: This action is effective January 

13, 2010. 

ADDRESSES: SIP materials which are 

incorporated by reference into 40 CFR 

part 52 are available for inspection at 

the following locations: Environmental 

Protection Agency, Region 4, 61 Forsyth 

Street, SW., Atlanta, GA 30303; the Air

FOR FURTHER INFORMATION CONTACT: Ms. 

Twunjala Bradley at the above Region 4 

address or at (404) 562–9352. 

SUPPLEMENTARY INFORMATION: Each state 

has a SIP containing the control 

measures and strategies used to attain 

and maintain the national ambient air 

quality standards (NAAQS). The SIP is 

extensive, containing such elements as 

air pollution control regulations, 

emission inventories, monitoring 

networks, attainment demonstrations, 

and enforcement mechanisms. 

Each state must formally adopt the 

control measures and strategies in the 

SIP after the public has had an 

opportunity to comment on them and 

then submit the SIP to EPA. Once these 

control measures and strategies are 

approved by EPA, after notice and 

comment, they are incorporated into the 

federally approved SIP and are 

identified in part 52 ‘‘Approval and 

Promulgation of Implementation Plans,’’ 

Title 40 of the Code of Federal 

Regulations (40 CFR part 52). The full 

text of the state regulation approved by 

EPA is not reproduced in its entirety in 

40 CFR part 52, but is ‘‘incorporated by 

reference.’’ This means that EPA has 

approved a given state regulation with 

a specific effective date. The public is 

referred to the location of the full text 

version should they want to know 

which measures are contained in a 

given SIP. The information provided 

allows EPA and the public to monitor 

the extent to which a state implements 

a SIP to attain and maintain the NAAQS 

and to take enforcement action if 

necessary. 

The SIP is a living document which 

the state can revise as necessary to 

address the unique air pollution 

problems in the state. Therefore, EPA 

from time to time must take action on 

SIP revisions containing new and/or 

revised regulations as being part of the 

SIP. On May 22, 1997, (62 FR 27968), 

EPA revised the procedures for 

incorporating by reference, into the 

CFR, materials submitted by states in 

their EPA-approved SIP revisions. These 

changes revised the format for the 

identification of the SIP in 40 CFR part 

52, stream-lined the mechanisms for 

announcing EPA approval of revisions 

to a SIP, and stream-lined the 

mechanisms for EPA’s updating of the 

IBR information contained for each SIP 

in 40 CFR part 52. The revised 

procedures also called for EPA to 

maintain ‘‘SIP Compilations’’ that 

contain the federally-approved 

regulations and source specific permits 

submitted by each state agency. These 

SIP Compilations are contained in 3- 

ring binders and are updated primarily 

on an annual basis. Under the revised 

procedures, EPA is to periodically 

publish an informational document in 

the rules section of the Federal Register 

when updates are made to a SIP 

Compilation for a particular state. EPA’s 

1997 revised procedures were formally 

applied to Mississippi on July 1, 1997 

(62 FR 35441).

Federal Register / Vol. 75, No. 8 / Wednesday, January 13, 2010 / Rules and Regulations 1713 

This action represents EPA’s 

publication of the Mississippi SIP 

Compilation update, appearing in 40 

CFR part 52. In addition, notice is 

provided of the following typographical 

corrections to Table (c) of paragraph 

52.1270, as described below: 

1. Correcting typographical errors listed in 

Table 1 of paragraph 52.127(c), as described 

below: 

A. State Citation APC–S–1 Section 6 State 

Effective Date is revised to read ‘‘5/28/99.’’ 

B. State Citation APC–S–2 Sections I thru 

XVII EPA Approval Date and Citation is 

revised to read ‘‘7/10/06, 71 FR 38773’’ 

respectively. 

C. State Citation APC–S–2 Section I State 

Effective Date is revised to read ‘‘8/27/05.’’ 

D. State Citation APC–S–2 Section XVI EPA 

Approval Date Citation is revised to read 

‘‘71 FR 38773.’’ 

E. State Citation APC–S–2 is revised to read, 

‘‘Section I.’’ 

F. State Citation APC–S–3 Section 2 is 

revised to read ‘‘2/4/72.’’ 

2. Revising the date format listed in 

paragraphs 52.1270(c). Revise the date format 

in the ‘‘State effective date,’’ and ‘‘EPA 

approval date,’’ columns for consistency. 

Dates are numerical month/day/year without 

additional zeros. 

EPA has determined that today’s 

action falls under the ‘‘good cause’’ 

exemption in the section 553(b)(3)(B) of 

the Administrative Procedure Act (APA) 

which, upon finding ‘‘good cause,’’ 

authorizes agencies to dispense with 

public participation and section 

553(d)(3) which allows an agency to 

make an action effective immediately 

(thereby avoiding the 30-day delayed 

effective date otherwise provided for in 

the APA). Today’s administrative action 

simply codifies provisions which are 

already in effect as a matter of law in 

Federal and approved state programs 

and corrects typographical errors 

appearing the Federal Register. Under 

section 553 of the APA, an agency may 

find good cause where procedures are 

‘‘impractical, unnecessary, or contrary to 

the public interest.’’ Public comment for 

this administrative action is 

‘‘unnecessary’’ and ‘‘contrary to the 

public interest’’ since the codification 

(and typographical corrections) only 

reflect existing law. Immediate notice of 

this action in the Federal Register 

benefits the public by providing the 

public notice of the updated Mississippi 

SIP Compilation and notice of 

typographical corrections to the 

Mississippi ‘‘Identification of Plan’’ 

portion of the Federal Register. 

Statutory and Executive Order Reviews 

A. General Requirements 

Under Executive Order 12866 (58 FR 

51735, October 4, 1993), this 

administrative action is not a 

‘‘significant regulatory action’’ and is 

therefore not subject to review by the 

Office of Management and Budget. This 

action is not subject to Executive Order 

13211, ‘‘Actions Concerning Regulations 

That Significantly Affect Energy Supply, 

Distribution, or Use’’ (66 FR 28355, May 

22, 2001) because it is not a significant 

regulatory action under Executive Order 

12866. Because the Agency has made a 

‘‘good cause’’ finding that this action is 

not subject to notice-and-comment 

requirements under the APA or any 

other statute as indicated in the 

Supplementary Information section 

above, it is not subject to the regulatory 

flexibility provisions of the Regulatory 

Flexibility Act (5 U.S.C 601 et seq.), or 

to sections 202 and 205 of the Unfunded 

Mandates Reform Act (UMRA) of 1995 

(Pub. L. 104–4). In addition, this action 

does not significantly or uniquely affect 

small governments or impose a 

significant intergovernmental mandate, 

as described in sections 203 and 204 of 

UMRA. This administrative action also 

does 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), nor will 

it 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 administrative 

action also is not subject to Executive 

Order 13045 (62 FR 19885, April 23, 

1997), because it is not economically 

significant. This administrative action 

does not involve technical standards; 

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. The 

administrative action also does not 

involve special consideration of 

environmental justice related issues as 

required by Executive Order 12898 (59 

FR 7629, February 16, 1994). This 

administrative action does not impose 

an information collection burden under 

the Paperwork Reduction Act of 1995 

(44 U.S.C. 3501 et seq.). EPA’s 

compliance with these Statutes and 

Executive Orders for the underlying 

rules are discussed in previous actions 

taken on the State’s rules. 

B. Submission to Congress and the 

Comptroller General 

The Congressional Review Act (CRA) 

(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. Section 808 allows 

the issuing agency to make a rule 

effective sooner than otherwise 

provided by the CRA if the agency 

makes a good cause finding that notice 

and public procedure is impracticable, 

unnecessary or contrary to the public 

interest. Today’s administrative action 

simply codifies (and corrects) 

provisions which are already in effect as 

a matter of law in Federal and approved 

State programs. 5 U.S.C. 808(2). These 

announced actions were effective when 

EPA approved them through previous 

rulemaking actions. EPA will submit a 

report containing this action 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 this action 

in the Federal Register. This update to 

Mississippi’s SIP Compilation and 

correction of typographical errors is not 

a ‘‘major rule’’ as defined by 5 U.S.C. 

804(2). 

C. Petitions for Judicial Review 

EPA has also determined that the 

provisions of section 307(b)(1) of the 

Clean Air Act pertaining to petitions for 

judicial review are not applicable to this 

action. This action is simply an 

announcement of prior rulemakings that 

have previously undergone notice and 

comment rulemaking. Prior EPA 

rulemaking actions for each individual 

component of the Mississippi SIP 

compilation previously afforded 

interested parties the opportunity to file 

a petition for judicial review in the 

United States Court of Appeals for the 

appropriate circuit within 60 days of 

such rulemaking action.

District 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: EPA is finalizing approval of 

revisions to the San Joaquin Valley 

Unified Air Pollution Control District 

(SJVAPCD) portion of the California 

State Implementation Plan (SIP). These 

revisions were proposed in the Federal 

Register on August 14, 2009 and 

concern oxides of nitrogen (NOX) and 

particulate matter (PM) emissions from 

boilers of various capacities. We are 

approving local rules that regulate these 

emission sources under the Clean Air 

Act as amended in 1990 (CAA or the 

Act). 

DATES: Effective Date: This rule is 

effective on February 12, 2010. 

ADDRESSES: EPA has established docket 

number EPA–R09–OAR–2009–0474 for 

this action. The index to the docket is

IV. Statutory and Executive Order Reviews 

I. Proposed Action 

On August 14, 2009 (74 FR 41104), 

EPA proposed to approve the following 

rules into the California SIP. 

Local agency Rule No. Rule title Adopted Submitted 

SJVAPCD ...................................................... 4306 Boilers, Steam Generators and Process Heaters— 

Phase 3.

10/16/08 03/17/09 

SJVAPCD ...................................................... 4307 Boilers, Steam Generators and Process Heaters—2.0 

MMbtu/hr to 5.0 MMbtu/hr.

10/16/08 03/17/09 

We proposed to approve these rules 

because we determined that they 

complied with the relevant CAA 

requirements. Our proposed action 

contains more information on the rules 

and our evaluation. 

II. Public Comments and EPA 

Responses 

EPA’s proposed action provided a 30- 

day public comment period. During this 

period, we received no comments. 

III. EPA Action 

Since publication of the proposed 

action, we identified two minor issues 

regarding Rule 4307 that do not change 

our assessment that the submitted rule 

complies with the relevant CAA 

requirements. Nonetheless, revisions to 

these provisions should be made when 

the Rule is next revised. 

We have identified the possibility that 

some units that are subject to Rule 4307 

do not need exemptions from basic 

emission limits during start-up and 

shutdown periods as long as they are 

maintained and operated appropriately. 

For example, we believe that heater 

treaters which rely only on low-NOX

burners for compliance are capable of 

consistent compliance with the Rule’s 

basic emission limits during these 

periods. As a result, Section 5.4 should 

be revised to remove the start-up and 

shutdown exemption period for such 

devices. 

Currently Section 6.1.4 requires 

recordkeeping only if the start-up and 

shut-down event exceeds the limitations 

of the duration of such events in Section 

5.4.1 or 5.4.2. EPA recommends that 

Section 6.1.4 of Rule 4307 be revised to 

require records that specify the duration 

of all start-up and shut-down periods (at 

least for units located at Title V 

facilities). EPA notes that the limited 

applicability of the current version of 

6.1.4 may not be appropriate in other 

rules, particularly those where periodic 

or continuous monitoring is required. 

No comments were submitted that 

change our assessment that the 

submitted rules comply with the 

relevant CAA requirements. Therefore, 

as authorized in section 110(k)(3) of the 

Act, EPA is fully approving these rules 

into the California SIP.
