Approval of California Air Plan 

Revisions, Placer County Air Pollution 

Control District and Ventura County 

Air Pollution Control District 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Direct final rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is taking direct final 

action to approve revisions to the Placer 

County Air Pollution Control District 

(PCAPCD) and Ventura County Air 

Pollution Control District (VCAPCD) 

portions of the California State 

Implementation Plan (SIP). These 

revisions concern oxides of nitrogen 

(NOX) and carbon monoxide (CO) 

emissions from stationary gas turbines, 

boilers, steam generators, and process 

heaters. We are approving local rules 

that regulate these emission sources 

under the Clean Air Act (CAA or the 

Act). 

DATES: This rule is effective on 

September 30, 2016 without further 

notice, unless the EPA receives adverse 

comments by August 31, 2016. If we 

receive such comments, we will publish 

a timely withdrawal in the Federal 

Register to notify the public that this 

direct final rule will not take effect. 

ADDRESSES: Submit your comments, 

identified by Docket ID No. EPA–R09– 

OAR–2016–0262 at http://

www.regulations.gov, or via email to 

Andrew Steckel, Rules Office Chief, at 

Steckel.Andrew@epa.gov. For comments 

submitted at Regulations.gov, follow the 

online instructions for submitting

I. The State’s Submittal 

A. What rules did the State submit? 

Table 1 lists the rules addressed by 

this action with the dates that they were 

adopted by the local air agencies and 

submitted by the California Air 

Resources Board.

VCAPCD ......................................... 74.15.1 Boilers, Steam Generators, and 

Process Heaters.

Revised 6/23/2015 ......................... 11/13/2015 

On January 19, 2016, the EPA 

determined that the submittal for 

VCAPCD Rule 74.15.1 met the 

completeness criteria in 40 CFR part 51, 

appendix V, which must be met before 

formal EPA review. On April 19, 2016, 

the EPA determined that the submittal 

for PCAPCD Rule 250 met the 

completeness criteria. 

B. Are there other versions of these 

rules? 

We approved an earlier version of 

PCAPCD Rule 250 into the SIP on 

August 23, 1995, in 60 FR 43713, and 

an earlier version of VCAPCD Rule 

74.15.1 into the SIP on May 19, 2014, 

in 79 FR 28612. 

C. What is the purpose of the submitted 

rule revisions? 

NOX helps produce ground-level 

ozone, smog and particulate matter 

(PM), which harm human health and 

the environment. Section 110(a) of the 

CAA requires States to submit 

regulations that control NOX emissions. 

PCAPCD Rule 250 and VCAPCD Rule 

74.15.1 both limit the emissions of NOX

from their respective source categories. 

The revisions to PCAPCD Rule 250 

include the removal of exemptions for 

emissions resulting from startup and 

shutdown operations, and 

simplification of the emission limits for 

stationary gas turbines. VCAPCD Rule 

74.15.1 updates the testing regime and 

clarifies several exemptions for boilers, 

steam generators, and process heaters. 

The EPA’s technical support 

documents (TSDs) have more 

information about these rules. 

II. The EPA’s Evaluation and Action 

A. How is the EPA evaluating the rules? 

SIP rules must be enforceable (see 

CAA section 110(a)(2)), must not 

interfere with applicable requirements 

concerning attainment and reasonable 

further progress or other CAA 

requirements (see CAA section 110(l)), 

and must not modify certain SIP control 

requirements in nonattainment areas 

without ensuring equivalent or greater 

emissions reductions (see CAA section 

193). 

SIP provisions cannot include 

exemptions from emission limitations 

for emissions during startup, shutdown, 

and malfunction (SSM) events. Thus, in 

order to be permissible in a SIP, 

emission limitations must apply 

continuously, i.e., they cannot include 

periods during which emissions are 

legally or functionally exempt from 

regulation (see CAA sections 110(a)(2) 

and 302(k)). EPA recently clarified this 

requirement for periods of startup, 

shutdown, and malfunction. See 

Restatement and Update of EPA’s SSM 

Policy Applicable to SIPs, 80 FR 33839 

(June 12, 2015). 

Generally, SIP rules must require 

reasonably available control technology 

(RACT) for each major source of NOX in 

ozone nonattainment areas classified as 

moderate or above (see CAA sections 

182(b)(2) and 182(f)). PCAPCD regulates 

an ozone nonattainment area classified 

as Severe for the 1994 1-hour ozone 

National Ambient Air Quality Standard 

(NAAQS), and for the 1997 and 2008 8- 

hour ozone NAAQS (40 CFR 81.305). 

VCAPCD also regulates an ozone 

nonattainment area classified as Severe 

for the 1994 1-hour ozone NAAQS and 

for the 1997 and 2008 8-hour ozone 

NAAQS (40 CFR 81.305). Therefore, 

PCAPCD Rule 250 and VCAPCD Rule 

74.15.1 must both implement RACT as 

the Districts regulate ozone 

nonattainment areas classified as 

Severe. 

Guidance and policy documents that 

we used to evaluate enforceability, 

revision/relaxation and rule stringency 

requirements for the applicable criteria 

pollutants include the following: 

1. ‘‘State Implementation Plans; General 

Preamble for the Implementation of Title 

I of the Clean Air Act Amendments of 

1990,’’ (57 FR 13498, April 16, 1992 and 

57 FR 18070, April 28, 1992). 

2. ‘‘Issues Relating to VOC Regulation 

Cutpoints, Deficiencies, and Deviations’’ 

(‘‘the Bluebook,’’ U.S. EPA, May 25, 

1988; revised January 11, 1990). 

3. ‘‘Guidance Document for Correcting 

Common VOC & Other Rule 

Deficiencies’’ (‘‘the Little Bluebook’’, 

EPA Region 9, August 21, 2001). 

4. ‘‘State Implementation Plans; Nitrogen 

Oxides Supplement to the General 

Preamble; Clean Air Act Amendments of 

1990 Implementation of Title I; Proposed 

Rule’’ (‘‘the NOX Supplement,’’ 57 FR 

55620, November 25, 1992). 

5. ‘‘Alternative Control Techniques 

Document—NOX Emissions from 

Stationary Gas Turbines,’’ (EPA–453/R– 

93–007), Emissions Standards Division, 

EPA OAQPS, January 1993. 

6. ‘‘Control Techniques for Nitrogen Oxides 

Emissions from Stationary Sources— 

Second Edition,’’ (EPA–450/1–78–001), 

January 1978. 

7. ‘‘Alternative Control Techniques 

Document—NOX Emissions from Process 

Heaters (Revised),’’ (EPA–453/R93–034), 

September 1993. 

8. ‘‘Determination of Reasonably Available 

Control Technology and Best Available 

Retrofit Control Technology for 

Industrial, Institutional, and Commercial 

Boilers, Steam Generators, and Process 

Heaters,’’ California Air Resources Board

9. ‘‘Restatement and Update of EPA’s SSM 

Policy Applicable to SIPs,’’ 80 FR 33839, 

June 12, 2015. 

B. Do the rules meet the evaluation 

criteria? 

We believe these rules are consistent 

with the relevant policy and guidance 

regarding enforceability, RACT, SIP 

relaxations, and requirements for 

emissions that occur during SSM 

events. The TSDs have more 

information on our evaluation. 

C. EPA Recommendations To Further 

Improve the Rules 

The TSDs describe additional rule 

revisions that we recommend for the 

next time the local agency modifies the 

rules but are not currently the basis for 

rule disapproval. 

D. Public Comment and Final Action 

As authorized in section 110(k)(3) of 

the Act, the EPA is fully approving the 

submitted rules because we believe they

50350 Federal Register / Vol. 81, No. 147 / Monday, August 1, 2016 / Rules and Regulations 

1Upon the effective date of this final action, 

submitted PCAPCD Rule 250 would supersede 

existing PCAPCD Rule 250, approved at 60 FR 

43713 in the applicable SIP. Submitted VCAPCD 

Rule 74.15.1 would supersede existing VCAPCD 

Rule 74.15.1, approved at 79 FR 28612. 

fulfill all relevant requirements.1 We do 

not think anyone will object to this 

approval, so we are finalizing it without 

proposing it in advance. However, in 

the Proposed Rules section of this 

Federal Register, we are simultaneously 

proposing approval of the same 

submitted rule. If we receive adverse 

comments by August 31, 2016, we will 

publish a timely withdrawal in the 

Federal Register to notify the public 

that the direct final approval will not 

take effect and we will address the 

comments in a subsequent final action 

based on the proposal. If we do not 

receive timely adverse comments, the 

direct final approval will be effective 

without further notice on September 30, 

2016. This will incorporate these rules 

into the federally enforceable SIP. 

Please note that if the EPA receives 

adverse comment on an amendment, 

paragraph, or section of this rule and if 

that provision may be severed from the 

remainder of the rule, the EPA may 

adopt as final those provisions of the 

rule that are not the subject of an 

adverse comment. 

III. Incorporation by Reference 

In this rule, the EPA is finalizing 

regulatory text that includes 

incorporation by reference. In 

accordance with requirements of 1 CFR 

51.5, the EPA is finalizing the 

incorporation by reference of the 

PCAPCD and VCAPCD rules described 

in the amendments to 40 CFR part 52 set 

forth below. The EPA has made, and 

will continue to make, these documents 

available electronically through 

www.regulations.gov and in hard copy 

at U.S. Environmental Protection 

Agency Region IX (Air-4), 75 Hawthorne 

Street, San Francisco, CA, 94105–3901. 

IV. Statutory and Executive Order 

Reviews 

Under the Clean Air Act, 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 Clean Air 

Act. 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); 

• 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 Clean Air Act; 

and 

• does not provide the 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, 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 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). 

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. The 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 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 Clean 

Air Act, petitions for judicial review of 

this action must be filed in the United 

States Court of Appeals for the 

appropriate circuit by September 30, 

2016. Filing a petition for 

reconsideration by the Administrator of 

this final rule does not affect the finality 

of this action 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. Parties with objections to this 

direct final rule are encouraged to file a 

comment in response to the parallel 

notice of proposed rulemaking for this 

action published in the Proposed Rules 

section of today’s Federal Register, 

rather than file an immediate petition 

for judicial review of this direct final 

rule, so that the EPA can withdraw this 

direct final rule and address the 

comment in the proposed rulemaking. 

This action may not be challenged later 

in proceedings to enforce its 

requirements (see section 307(b)(2)).

Federal Register / Vol. 81, No. 147 / Monday, August 1, 2016 / Rules and Regulations 50351 

1On June 26, 2012, EPA finalized a limited 

approval of Missouri’s August 5, 2009, regional 

haze SIP to address the first implementation period 

for regional haze (77 FR 38007). In a separate 

action, published on June 7, 2012 (77 FR 33642), 

EPA finalized a limited disapproval of the Missouri 

regional haze SIP because of the State’s reliance on 

the Clean Air Interstate Rule to meet certain 

regional haze requirements, which EPA replaced in 

August 2011 with the Cross-State Air Pollution Rule 

(CSAPR) (76 FR 48208 (Aug. 8, 2011)). In the 

aforementioned June 7, 2012, action, EPA finalized 

a Federal Implementation Plan (FIP) for Missouri to 

replace the State’s reliance on CAIR with reliance 

on CSAPR. Following these EPA actions, the D.C. 

Circuit issued a decision in EME Homer City 

Generation, L.P. v. EPA (‘‘EME Homer City’’), 696 

F. 3d 7 (D.C. Cir. 2012), vacating CSAPR and 

keeping CAIR in place pending the promulgation of 

a valid replacement rule. On April 29, 2014, the 

U.S. Supreme Court reversed the D.C. Circuit 

opinion vacating CSAPR, and remanded the case for 

further proceedings. EME Homer City, 572 U.S. 134 

S. Ct. 1584. In the interim, CAIR remained in place. 

On October 23, 2014, the D.C. Circuit granted EPA’s 

motion to lift the stay on CSAPR. Order of October 

23, 2014, in EME Homer City, D.C. Cir. No. 11– 

1302. EPA issued an interim final rule to clarify 

how EPA will implement CSAPR consistent with 

the D.C. Circuit’s order. 79 FR 71663 (December 3, 

2014) (interim final rulemaking). Subsequent to the 

interim final rulemaking, EPA began 

implementation of CSAPR on January 1, 2015.

and 2013 Five-Year Progress Report 

AGENCY: Environmental Protection 

Agency. 

ACTION: Final rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is taking final action to 

approve the Missouri State 

Implementation Plan (SIP) revision 

submitted to EPA by the State of 

Missouri on August 5, 2014, 

documenting that the State’s existing 

plan is making adequate progress to 

achieve visibility goals by 2018. The 

Missouri SIP revision addressed the 

Regional Haze Rule (RHR) requirements 

under the Clean Air Act (CAA or Act) 

to submit a report describing progress in 

achieving reasonable progress goals 

(RPGs) to improve visibility in Federally 

designated areas in nearby states that 

may be affected by emissions from 

sources in Missouri. EPA is taking final 

action to approve Missouri’s 

determination that the existing Regional 

Haze (RH) SIP is adequate to meet the 

visibility goals and requires no 

substantive revision at this time. 

DATES: This final rule is effective August 

31, 2016.

58410), EPA published a notice of 

proposed rulemaking (NPR) for the State 

of Missouri. In the NPR, EPA proposed 

approval of Missouri’s progress report 

SIP, a report on progress made in the 

first implementation period towards 

RPGs for Class I areas that are affected 

by emissions from Missouri sources. 

This progress report SIP and 

accompanying cover letter also included 

a determination that Missouri’s existing 

regional haze SIP requires no 

substantive revision to achieve the 

established regional haze visibility 

improvement and emissions reduction 

goals for 2018. 

States are required to submit a 

progress report in the form of a SIP 

revision every five years that evaluates 

progress towards the RPGs for each 

mandatory Class I Federal area within 

the state and in each mandatory Class I 

Federal area outside the state which 

may be affected by emissions from 

within the state. See 40 CFR 51.308(g). 

In addition, the provisions under 40 

CFR 51.308(h) require states to submit, 

at the same time as the 40 CFR 51.308(g) 

progress report, a determination of the 

adequacy of the state’s existing regional 

haze SIP. The first progress report SIP 

is due five years after submittal of the 

initial regional haze SIP. The Missouri 

Department of Natural Resources 

(MDNR) submitted its regional haze SIP 

on August 5, 2009, and a supplement on 

January 30, 2012, in accordance with 40 

CFR 51.308(b).1

On February 14, 2014, MDNR 

provided to the Federal Land Managers 

a revision to Missouri’s SIP reporting on 

progress made during the first 

implementation period toward RPGs for 

Class I areas in the state and Class I 

areas outside the state that are affected 

by Missouri sources. Missouri has two 

Class I areas, Mingo National Wildlife 

Refuge (Mingo) and Hercules Glades 

Wilderness Area (Hercules Glades). 

Missouri also hosts an additional
