SUPPLEMENTARY INFORMATION:

I. Background

On March 10, 2017 (82 FR 13235), the EPA published a direct final rule (DFR) approving two SIP revisions submitted by the Nevada Division of Environmental Protection. On April 3, 2012, the State submitted to the EPA a CO maintenance plan as a SIP revision. This 2012 maintenance plan was intended to meet the CAA requirement (see CAA section 175A(b)) to submit a second maintenance plan. The CAA requires that, in the eighth year of an area's first 10-year maintenance plan, a second maintenance plan be submitted covering an additional ten years beyond the first 10-year period. Subsequently, on August 26, 2016, the State submitted a supplement to their 2012 submittal.

In the March 10, 2017 DFR, the EPA also approved a surrogate monitoring method for the State to monitor ambient levels of CO in the area. This surrogate monitoring method was described in both the 2012 submittal and 2016 supplement, with the 2016 supplement containing the State's final intended method.

In the March 10, 2017 DFR, the EPA stated that if adverse comments were received by April 10, 2017, the EPA would publish a timely withdrawal and address the comments in a subsequent final rule based on the notice of proposed rulemaking (NPR), also published on March 10, 2017 (82 FR 13269).

In this instance, the EPA received an adverse comment on the alternative monitoring strategy and attempted to withdraw the DFR prior to the effective date of May 9, 2017. However, the EPA inadvertently did not withdraw the DFR prior to that date and the rule prematurely became effective on May 9, 2017, revising the State's SIP to include the 2012 submittal and 2016 supplement on that date.

In today's final rule, the EPA is responding to the comment submitted on the EPA's proposed approval of revisions to the State's SIP, is approving the 2012 SIP submittal and 2016 supplement into the SIP, and is amending the effective date of the regulations' inclusion in the SIP to correct our failure to withdraw the DFR (after the EPA received an adverse public comment) prior to the May 9, 2017 effective date of the DFR.

II. Summary of SIP Revision and the EPA's Analysis

As described in the DFR, the State's 2012 submittal was a limited maintenance plan (LMP). A LMP is appropriate for CO areas that are below 85 percent of the 8-hour CO national ambient air quality standards (NAAQS). The following are the key elements of a LMP for CO: Attainment inventory, maintenance demonstration, monitoring network, verification of continued attainment, contingency plan, and conformity determinations.[1]

The 2012 plan contains the following sections to address these elements: (1) An introductory section containing a general discussion of plan approvals for the area and its redesignation to attainment; (2) a maintenance plan section including subsections on monitoring data for the area, air quality trends and background on the State's intention to discontinue monitoring CO at the only remaining gaseous CO ambient monitor in the Lake Tahoe basin located at Harvey's Resort and Hotel in Stateline, Nevada (hereinafter, the ”Harvey's monitor”); (3) a section titled ”Verification of Continued Attainment” that addresses population change, traffic volumes, meteorology and the State's surrogate monitoring method; (4) contingency measures for the area; and (5) transportation conformity requirements.

The 2016 supplement revises several sections of the 2012 plan and contains an emissions inventory. The DFR describes our evaluation of the 2012 plan and 2016 supplement as they pertain to each of the required LMP elements.[2] Although we approved the State's surrogate monitoring method in the DFR, we took no action on the State's monitor shutdown request and anticipate acting on the request in a separate action after we review the State's annual network plan and finalize this action.

As described in the DFR, this action incorporates the 2012 plan, as amended by the 2016 supplement, and specific portions of the 2016 supplement itself, into the federally enforceable SIP. Together, these two submittals meet the applicable CAA requirements, and the EPA has determined they are sufficient to provide for maintenance of the CO NAAQS over the course of the second 10-year maintenance period through 2024.

III. Public Comment and the EPA's Response

The EPA received an adverse comment from an anonymous commenter (“commenter”) on March 14, 2017.[3]

Comment Summary: The commenter noted their support for the EPA's action, stating that it would have a positive effect on the environment and would benefit the public. However, the commenter went on to comment adversely on the EPA's approval of the State's surrogate monitoring method, because monitoring methods are important to safeguard against a possible return of high levels of CO occurring in the region again, and the plan the EPA was approving did not offer any scenarios for reinstating monitoring.

Response: The EPA acknowledges the commenter's support. However, we disagree with some of the assertions and conclusions in the comment. First, the text the commenter quoted from our action was taken from the Code of Federal Regulations (CFR). The text the commenter quoted was that monitoring may be discontinued if the monitor in question has not measured violations of the applicable NAAQS in the previous five years. This text is not something that the EPA was proposing to approve in our action, but rather is text from the existing CFR (40 CFR part 58), that, in a general sense, describes the circumstances that the EPA evaluates in determining whether to allow discontinuation of a monitor. We are not acting on a general policy regarding the circumstances under which ambient monitoring may be discontinued, nor are we acting on a specific instance of a monitor's discontinuation. Rather, we said in the DFR that we are not taking action on the State's request to shut down the Harvey's monitor, and that the EPA would respond to the State's Start Printed Page 26353request in a separate action. We are instead approving a surrogate monitoring method for the State to use in the area.

In addition, we believe the commenter is factually incorrect in stating that nothing is offered to reinstate ambient CO monitors “if CO were ever to plague the region again.” To the contrary, the EPA explained in the DFR the circumstances under which ambient monitoring would be re-started. The surrogate monitoring method is a method of monitoring that relies on indirect indicators (traffic counts) to be monitored during the entire second maintenance period, and that have in fact already commenced. The EPA has already received several years' worth of traffic count reports from the State. The surrogate monitoring method using traffic counts is an ongoing effort of the State, performed at two locations in the area. Further, if the traffic counts rise above trigger levels, the State will re-start ambient monitoring. Lastly, once ambient monitoring is triggered, specific stringent conditions must be met to discontinue ambient CO monitoring. This will be the case even if the EPA, in a separate future action, approves the State's 2012 request to discontinue ambient CO monitoring. That is, even if the EPA approves the shutdown of the Harvey's ambient CO monitor per the State's 2012 request, a triggered re-start of the monitor (“triggered monitoring”) would set in motion specific requirements before triggered monitoring could be discontinued. Regardless of the status of ambient CO monitoring, the State's traffic counts at two locations remain in place and are required by today's action to be continued throughout the maintenance period, through the end of 2024. The commenter did not provide any data or rationale for why monitoring methods should be addressed further.

IV. Final Action

The EPA is approving revisions to the Nevada SIP. The revisions incorporate the 2012 maintenance plan and 2016 supplement. The EPA is also amending the effective date of the inclusion of these revisions to the State's SIP because the revisions were added to the SIP prematurely on May 9, 2017, when the EPA did not withdraw its DFR after receiving a comment on our approval of the State's two SIP submittals. This rule responds to the comment received, finalizes our approval and corrects the effective date for inclusion of the State's two submittals into the SIP.

V. Statutory and Executive Order Reviews

A. General Requirements

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, 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);
  • 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 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, this rule 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 the EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.

B. Submission to Congress and the Comptroller General

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, that 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).

C. Petitions for Judicial Review

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 7, 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 shall not postpone the effectiveness of such rule or action.

This action approving the revisions to the State of Nevada's SIP may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
