ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 62

[EPA-R08-OAR-2017-0171; FRL-9963-21-Region 8]


Approval and Promulgation of State Plans for Designated 
Facilities and Pollutants: Colorado, Montana, North Dakota, South 
Dakota, Utah, and Wyoming; Negative Declarations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: With this direct final rule, the Environmental Protection 
Agency (EPA) is taking action to approve the negative declarations for 
several designated facility classes in various states of Region 8. 
First, the EPA is taking direct final action in approving the negative 
declarations for small municipal waste combustor (MWC) units submitted 
by the states of Colorado, Montana, North Dakota, South Dakota, and 
Wyoming. Second, the EPA is taking direct final action in approving the 
negative declarations for large MWC units submitted by the states of 
Colorado, Montana, North Dakota, South Dakota, Utah, and Wyoming. 
Third, the EPA is taking direct final action in approving the negative 
declarations for commercial industrial solid waste incineration (CISWI) 
units submitted by the states of Montana, South Dakota, Utah, and 
Wyoming. Fourth, the EPA is taking direct final action in approving the 
negative declarations for other solid waste incineration (OSWI) units 
submitted by the states of Montana, North Dakota, South Dakota, Utah, 
and Wyoming. Each state included in this action has notified the EPA in 
a letter of negative declaration that there are no existing designated 
facilities, of the source category specified in each particular letter 
of negative declaration, subject to the requirements of sections 111(d) 
and 129 of the Clean Air Act (CAA or the ``Act'') currently operating 
within the jurisdictional boundaries of their state. The EPA is 
accepting the negative declarations in accordance with sections 111(d) 
and 129(b) of the Act. This is a direct final action without prior 
notice and comment because the action is deemed noncontroversial.

DATES: This direct final rule is effective on August 4, 2017 without 
further notice, unless the EPA receives adverse written comments on or 
before July 5, 2017. If adverse comments are received, the EPA will 
publish a timely withdrawal of the direct final rule in the Federal 
Register informing the public that the rule will not take effect.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R08-
OAR-2017-0171 at http://www.regulations.gov. Follow the online 
instructions for submitting comments. Once submitted, comments cannot 
be edited or removed from Regulations.gov. The EPA may publish any 
comment received to its public docket. Do not submit electronically any 
information you consider to be Confidential Business Information (CBI) 
or other information whose disclosure is restricted by statute. 
Multimedia submissions (audio, video, etc.) must be accompanied by a 
written comment. The written comment is considered the official comment 
and should include discussion of all points you wish to make. The EPA 
will generally not consider comments or comment contents located 
outside of the primary submission (i.e., on the web, cloud, or other 
file sharing system). For additional submission methods, the full EPA 
public comment policy, information about CBI or multimedia submissions,

SUPPLEMENTARY INFORMATION: 

I. Why is EPA using a direct final rule?

    The EPA is publishing this rule without prior proposal because the 
agency views this as a noncontroversial action and anticipates no 
adverse comments. However, in the Proposed Rules section of today's 
Federal Register publication, the EPA is publishing a separate document 
that will serve as the proposal to publish the negative declarations 
should relevant adverse comments be filed. This rule will be effective 
August 4, 2017 without further notice unless the agency receives 
relevant adverse comments by July 5, 2017.
    If the EPA receives adverse comments, the EPA will publish a timely 
withdrawal in the Federal Register informing the public that this 
direct final rule will not take effect. The EPA will address all public 
comments in a subsequent final rule based on the proposed rule. The EPA 
will not institute a second comment period on this action. Any parties 
interested in commenting must do so at this time. 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.

II. Background

    The EPA's statutory authority for regulating new and existing solid 
waste incineration units is outlined in CAA sections 111 and 129. 
Section 129 of the

[[Page 25735]]

Act is specific to solid waste combustion, and requires the EPA to 
establish performance standards for each category of solid waste 
incineration units, which includes the categories addressed in today's 
notice. Section 111(b) of the Act gives the EPA the statutory authority 
to promulgate new source performance standards (NSPS) for new 
incineration units. Section 111(d) requires states to submit plans to 
control designated pollutants at existing incineration facilities 
(designated facilities) whenever standards of performance have been 
established under section 111(b) and the EPA has established emission 
guidelines for existing designated facilities. Emission guidelines are 
implemented and enforced by state pollution control agencies through 
these EPA-approved section 111(d)/129 state plans or a promulgated 
federal plan adopted by the state. If a state does not have any 
existing solid waste incineration units for the relevant emission 
guidelines, the state shall submit a letter to the EPA certifying that 
no such units exist within the state (i.e., negative declaration) in 
lieu of a state plan.
    Emission guidelines for small MWC units were originally promulgated 
alongside guidelines for large MWC units in December 1995 (40 CFR part 
60, subpart Cb). These guidelines were vacated by the U.S. Court of 
Appeals for the District of Columbia Circuit in March 1997 when the 
court held that the EPA should separately regulate small MWC units to 
remain consistent with the provisions of section 129 of the CAA. On 
December 6, 2000, the EPA issued a final rule (65 FR 76378) to 
reestablish emission guidelines and compliance times for existing small 
MWC units constructed on or before August 30, 1999, that have 
capacities of 35 to 250 tons per day of municipal solid waste (40 CFR 
part 60, subpart BBBB). The federal plan was promulgated on January 31, 
2003 (68 FR 5144), at 40 CFR part 62, subpart JJJ.
    In December 1995, the EPA adopted NSPS (40 CFR part 60, subpart Eb) 
and emission guidelines (40 CFR part 60, subpart Cb) for large MWC 
units. The EPA conducted a five-year review of the NSPS and emission 
guidelines for large MWC units as required by section 129(a)(5) of the 
CAA and proposed amendments on December 19, 2005 (70 FR 75348). On May 
10, 2006, after consideration of comments received on this proposal, 
revisions and amendments to the emission guidelines and compliance 
times for large MWC units were promulgated at 40 CFR part 60, subpart 
Cb (71 FR 27323).
    On February 7, 2013, revision of the emission guidelines and 
compliance times for commercial and industrial solid waste incineration 
units was adopted and promulgated (78 FR 9112) at 40 CFR part 60, 
subpart DDDD. Reconsideration of certain aspects of the final rule due 
to public comment resulted in minor amendments to the CISWI rule being 
made on June 23, 2016. On October 3, 2003, the EPA promulgated the 
federal plan for CISWI units that commenced construction on or before 
November 30, 1999 (68 FR 57539) at 40 CFR part 62, subpart III.
    On December 16, 2005, emission guidelines and compliance times were 
promulgated for existing other solid waste incineration units that 
commenced construction on or before December 9, 2004 (70 FR 74907) at 
40 CFR part 60, subpart FFFF. Reconsideration of certain aspects of the 
final rule resulted in minor amendments to the OSWI rule being made on 
January 22, 2007.

IV. Final Action

    The EPA is approving the negative declarations for existing small 
MWC units for the states of Colorado, Montana, North Dakota, South 
Dakota, and Wyoming. The negative declarations satisfy the requirements 
of 40 CFR 62.06 and will serve in lieu of CAA section 111(d)/129 state 
plans for the specified states and source category.
    The EPA is also approving the updated negative declarations for 
existing large MWC units for the states of Colorado, Montana, North 
Dakota, South Dakota, Utah, and Wyoming. The negative declarations 
satisfy the requirements of 40 CFR 62.06 and will serve in lieu of CAA 
section 111(d)/129 state plans for the specified states and source 
category.
    The EPA is also publishing the updated negative declarations for 
existing CISWI units for the states of Montana, South Dakota, Utah, and 
Wyoming. The negative declarations satisfy the requirements of 40 CFR 
62.06 and will serve in lieu of CAA section 111(d)/129 state plans for 
the specified states and source category.
    The EPA is also approving the negative declarations for existing 
OSWI units for the states of Montana, North Dakota, South Dakota, Utah, 
and Wyoming. The negative declarations satisfy the requirements of 40 
CFR 62.06 and will serve in lieu of CAA section 111(d)/129 state plans 
for the specified states and source category.

V. Statutory and Executive Order Review

    Under the CAA, the Administrator is required to approve a section 
111(d)/129 plan submission that complies with the provisions of the Act 
and applicable federal regulations at 40 CFR 62.04. Thus, in reviewing 
section 111(d)/129 plan 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

[[Page 25737]]

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 CAA; and,
     Is not subject to Executive Order 12898 (59 FR 7629, 
February 16, 1994) because it does not establish an environmental 
health or safety standard.
    In addition, this rule 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 CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by August 4, 2017. 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 it shall not postpone the effectiveness of such rule or 
action. Under CAA section 307(b)(2), this action may not be challenged 
later in proceedings to enforce its requirements.
