I. Analysis of the State Submittals
On December 14, 2004 and March 1, 2016, the State of North Carolina, through NCDEQ, submitted revisions to the North Carolina SIP. EPA is proposing to approve the March 1, 2016, submission which adds a new rule—15A NCAC 02Q .0809 Concrete Batch Plants and a portion of the December 14, 2004, submission which adds two new rules—15A NCAC 02Q .0901, Purpose and Scope and .0902 Portable Crushers. EPA has preliminarily determined that these changes to the North Carolina SIP are approvable pursuant to section 110 of the CAA. The changes that are the subject of this proposed rulemaking are described in further detail below.
A. March 1, 2016, SIP Submission
The March 1, 2016, submission adds a new exclusionary rule for concrete batch plants (15A NCAC 02Q .0809 Concrete Batch Plants) that excludes from Title V permitting requirements such facilities that operate below a specified annual production rate. The production rate that qualifies concrete batch plants for this permit exclusion is 1,210,000 cubic yards of wet concrete per year, which, based on an emission factor, corresponds to an emission rate below the major source threshold. Subject facilities are required to submit an annual registration to the appropriate regional office and report the quantity of wet concrete produced in the previous calendar year and maintain records of annual production for the previous three calendar years. This annual certification that the facility's production rate is below the specified level ensures continued protection of the NAAQS, specifically particulate matter, which is of particular relevance because concrete batch plants emit particulate matter, including particulate matter with an aerodynamic diameter less than 10 micrometers (PM10) and less than 2.5 micrometers (PM2.5). These excluded sources must also make prompt reports if they exceed the annual production rate limit, submitted within one week of the date on which the limit was exceeded.
The rule excludes from Title V permitting requirements all concrete batch plants in the state that produce Start Printed Page 31740less than 1.2 million cubic yards of wet concrete per calendar year and that are equipped with fabric filters or other functionally equivalent control devices to abate emissions of particulate matter, PM10 and PM2.5, from storage silos and weigh hoppers that receive materials from cement and mineral admixture silos. The annual production limit of 1.2 million cubic yards of wet concrete is designed to limit particulate matter emissions from plants equipped with fabric filters to less than the Title V permitting thresholds and is based on standard emission factors in use at the time of rule adoption.
B. December 14, 2004, SIP Submission
The portion of the December 14, 2004, SIP submission that EPA is proposing to approve adds a new section (Section .0900 Permit Exemptions), which includes the following two new regulations:
a. 15A NCAC 02Q .0901 Purpose and Scope is a new exclusionary rule which provides for exclusions from construction and operating permits for certain types of sources and activities. Sources subject to Title V permitting requirements are not eligible for exclusion under this rule. Sources eligible for permit exclusions under this rule may still apply for and receive construction and operating permits. At the time of this submittal, only one source category would be eligible for exclusion from permitting under Section .0900, if approved as proposed: Portable Crushers. The rule excludes from general construction and operating permitting requirements all specific listed sources that, due to the temporary, portable, and/or low-emitting nature of their operations, typically do not meet the applicability requirements for air permits, so long as they meet the requirements for the exclusion. These source-specific exclusions contain provisions that limit the sources' potential emissions, such as constraints on operating hours and fuel consumption. The exclusions' use of operational or production-based limits instead of potential-emissions limits would streamline sources' analyses of whether or not they are required to obtain a permit.
b. 15A NCAC 02Q .0902 Portable Crushers, is an exclusionary rule which provides for exclusions from construction and operating permits for portable crusher operations that meet the following criteria:
○ No more than 300,000 tons of material crushed per any 12-month period;
○ No more than 17,000 gallons of diesel fuel burned during any 12 months (for both diesel generators and diesel engines used to drive crushers);
○ No more than 12 months of operation at a particular site;
○ Continuous use of water spray to control emissions from the crushers.
Portable crushers operating at quarries with air permits are not eligible for this permit exclusion.
The rule excludes from general construction and operating permitting requirements portable/temporary crushing operations, providing the eligibility criteria listed above are met. The eligibility criteria are designed to ensure that these portable crushing operations do not operate for more than 12 months at a site. Records of production and fuel consumption must be maintained, and all equipment at each site must be labeled with unique identification numbers. The eligibility criteria are also based on corresponding emission rates and are thus designed to ensure that potential emissions of particulate matter (including PM10 and PM2.5), sulfur dioxide, and oxides of nitrogen from these sources are below relevant permit applicability thresholds. Therefore, the revision will not interfere with attainment and maintenance of the NAAQS pursuant to CAA section 110(l).
Crushing operations eligible for this permitting exclusion must still comply with all applicable air quality standards, such as Rule .0510 Particulates from Sand, Gravel, or Crushed Stone Operations, .0516 Sulfur Dioxide Emissions from Combustion Sources, and .0521 Control of Visible Emissions, and any New Source Performance Standard, among other state and federal air quality standards.
II. Incorporation by Reference
In this rule, EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, EPA is proposing to incorporate by reference 15A NCAC 02Q .0809 entitled “Concrete Batch Plants” effective April 1, 2004, a new exclusionary rule for concrete batch that excludes from Title V permitting requirements such facilities that operate below a specified annual production rate; 15A NCAC 02Q .0901 entitled “Purpose and Scope” effective January 1, 2005, a new exclusionary rule which provides for exclusions from construction and operating permits for certain types of sources and activities; and 15A NCAC 02Q .0902 entitled “Portable Crushers” effective January 1, 2005, an exclusionary rule which provides for exclusions from construction and operating permits for portable crusher operations. EPA has made, and will continue to make, these materials generally available through https://www.regulations.gov and/or at the EPA Region 4 office (please contact the person identified in the For Further Information Contact section of this preamble for more information).
III. Proposed Action
EPA is proposing to approve North Carolina's March 1, 2016, submission and a portion of the December 14, 2004, submission. The changes pertain to the addition of two new rules under a new section “Permit Exemptions” and adds a new rule to the “Exclusionary Rules” of the North Carolina SIP. These rule adoptions do not contravene federal permitting requirements or existing EPA policy, nor will they impact the NAAQS or interfere with any other applicable requirement of the Act. See 42 U.S.C. 7410(l).
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 Act and applicable federal regulations. See 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 proposed action merely approves state law as meeting federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, these proposed action:
- Are 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);
- do not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
- are 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.);
- do 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);Start Printed Page 31741
- do not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
- are not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
- are not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
- are 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
- do 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).
The SIP is not approved to apply on any Indian reservation land or in any other area where 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 as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it impose substantial direct costs on tribal governments or preempt tribal law.Start List of Subjects
