9VAC5-60-120. Applicability.

Article 3
Control Technology Determinations for Major Sources of Hazardous Air Pollutants (Rule 6-3)

A. The provisions of this article apply to any owner of an affected source within a source category or subcategory for which the administrator has failed to promulgate a MACT standard by the § 112(j) of the federal Clean Air Act deadline.

B. The provisions of this article apply throughout the Commonwealth of Virginia.

C. The provisions of this article do not apply to research or laboratory activities.

D. If federal operating permit program applicability has been deferred for a source category, the provisions of this article shall not apply for sources in that category until those sources become subject to federal operating permit requirements.

E. The procedures in this article apply for each affected source only after the § 112(j) deadline for the source category or subcategory in question has passed, and only until such time as a generally applicable emission standard governing that source has been promulgated. Once a generally applicable emission standard governing that source has been promulgated, the owner of the affected source and the board are not required to take any further actions to develop an equivalent emission limitation under this article.

F. Any final equivalent emission limitation for an affected source that is issued by the board pursuant to this article prior to promulgation of a generally applicable emission standard governing that source shall be deemed an applicable federal requirement adopted pursuant to § 112(j) of the federal Clean Air Act. Each such equivalent emission limitation shall take effect upon issuance of the federal operating permit containing that limitation and shall remain applicable to the source until such time as it may be revised or supplanted pursuant to the procedures established by this article. Such a final equivalent emission limitation, and all associated requirements adopted pursuant to 9VAC5-60-140 F 2, are directly enforceable under federal law regardless of whether any permit in which they may be contained remains in effect.

"Fugitive emissions" means those emissions from a stationary source that could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening. Under § 112 of the Clean Air Act, all fugitive emissions are to be considered in determining whether a stationary source is a major source.

"Hazardous air pollutant" means any air pollutant listed in § 112(b) of the federal Clean Air Act, as amended by 40 CFR 63.60.

"Hazardous air pollutant new source review permit" means a document issued pursuant to Article 7 (9VAC5-80-1400 et seq.) of Part II of 9VAC5 Chapter 80 containing all federally enforceable conditions necessary to enforce the application and operation of any maximum achievable control technology or other control technologies such that the MACT emission limitation is met.

"Hazardous air pollutant new source review program" means a program for the preconstruction review and permitting of new stationary sources that emit hazardous air pollutants in accordance with Article 7 (9VAC5-80-1400 et seq.) of Part II of 9VAC5 Chapter 80, promulgated to implement the requirements of § 112 (relating to permits for hazardous air pollutants) of the federal Clean Air Act.

"Major source" means any stationary source or group of stationary sources located within a contiguous area and under common control that emits or has the potential to emit considering controls, in the aggregate, 10 tons per year or more of any hazardous air pollutant or 25 tons per year or more of any combination of hazardous air pollutants, unless the board establishes a lesser quantity, or in the case of radionuclides, different criteria from those specified in this sentence.

"Maximum achievable control technology (MACT) emission limitation for existing sources" means the emission limitation reflecting the maximum degree of reduction in emissions of hazardous air pollutants (including a prohibition on such emissions, where achievable) that the board, taking into consideration the cost of achieving such emission reductions, and any nonair quality health and environmental impacts and energy requirements, determines is achievable by sources in the category or subcategory to which such a MACT standard applies. This limitation shall not be less stringent than the MACT floor.

"Maximum achievable control technology (MACT) emission limitation for new sources" means the emission limitation which is not less stringent than the emission limitation achieved in practice by the best controlled similar source, and which reflects the maximum degree of reduction in emissions of hazardous air pollutants (including a prohibition on such emissions, where achievable) that the board, taking into consideration the cost of achieving such emission reduction, and any nonair quality health and environmental impacts and energy requirements, determines is achievable by sources in the category or subcategory to which such a MACT standard applies.

"Maximum achievable control technology (MACT) floor" means:

1. For existing sources:

a. The average emission limitation achieved by the best performing 12% of the existing sources (for which the administrator has emissions information), excluding those sources that have, within 18 months before the emission standard is proposed or within 30 months before such standard is promulgated, whichever is later, first achieved a level of emission rate or emission reduction which complies, or would comply if the source is not subject to such standard, with the lowest achievable emission rate (as defined in 9VAC5-80-2010) applicable to the source category and prevailing at the time, in the category or subcategory, for categories and subcategories of stationary sources with 30 or more sources; or

b. The average emission limitation achieved by the best performing five sources (for which the administrator has or could reasonably obtain emissions information) in the category or subcategory, for a category or subcategory of stationary sources with fewer than 30 sources;

2. For new sources, the emission limitation achieved in practice by the best controlled similar source.

"Maximum achievable control technology (MACT) standard" means:

1. An emission standard;

2. An alternative emission standard;

3. An alternative emission limitation; or

4. An equivalent emission limitation established pursuant to § 112 of the federal Clean Air Act that applies to the collection of equipment, activities, or both, regulated by such standard or limitation.

A MACT standard may include or consist of a design, equipment, work practice, or operational requirement, or other measure, process, method, system, or technique (including prohibition of emissions) that the administrator or board establishes for new or existing sources to which such standard or limitation applies. Every MACT standard established pursuant to § 112 of the federal Clean Air Act includes Subpart A of 40 CFR Part 63, as provided by 40 CFR 63.1(a)(4), and all applicable appendices of 40 CFR Part 63 or of other parts of Title 40 of the Code of Federal Regulations that are referenced in that standard.

"Minor new source review (MNSR) permit" means a document issued pursuant to Article 6 (9VAC5-80-1100 et seq.) of Part II of 9VAC5 Chapter 80 containing all federally enforceable conditions necessary to enforce the application and operation of any best achievable control technology or other requirements such that the applicable requirements are met.

"New affected source" means the collection of equipment, activities, or both, that if constructed after the issuance of a permit for the source pursuant to 9VAC5-60-140, is subject to the applicable MACT emission limitation for new sources. Each permit shall define the term "new affected source," which will be the same as the "affected source" unless a different collection is warranted based on consideration of factors including:

1. Emission reduction impacts of controlling individual sources versus groups of sources;

2. Cost effectiveness of controlling individual equipment;

3. Flexibility to accommodate common control strategies;

4. Cost and benefits of emissions averaging;

5. Incentives for pollution prevention;

6. Feasibility and cost of controlling processes that share common equipment (e.g., product recovery devices);

7. Feasibility and cost of monitoring; and

8. Other relevant factors.

"New source" means any affected source the construction or reconstruction of which is commenced after the administrator first proposes a MACT standard under 40 CFR Part 63 establishing an emission standard applicable to such source.

"New source review program" means a program for the preconstruction review and permitting of new stationary sources or expansions to existing ones in accordance with Article 6 (9VAC5-80-1100 et seq.), Article 7 (9VAC5-80-1400 et seq.), Article 8 (9VAC5-80-1700 et seq.), or Article 9 (9VAC5-80-2000 et seq.) of Part II of 9VAC5 Chapter 80 promulgated to implement the requirements of §§ 110(a)(2)(c), 112 (relating to permits for hazardous air pollutants), 165 (relating to permits in prevention of significant deterioration areas), and 173 (relating to permits in nonattainment areas) of the federal Clean Air Act.

"Potential to emit" means the maximum capacity of a stationary source to emit a pollutant under its physical and operational design. Any physical or operational limitation on the capacity of the stationary source to emit a pollutant, including air pollution control equipment and restrictions on hours of operation or on the type or amount of material combusted, stored, or processed, shall be treated as part of its design if the limitation or the effect it would have on emissions is state and federally enforceable. Fugitive emissions count in determining the potential to emit of a stationary source.

"Reconstruction," unless otherwise defined in a MACT standard, means the replacement of components of an affected or a previously nonaffected source to such an extent that:

1. The fixed capital cost of the new components exceeds 50% of the fixed capital cost that would be required to construct a comparable new source; and

2. It is technologically and economically feasible for the reconstructed source to meet the MACT standards established by the administrator (or the board) pursuant to § 112 of the Clean Air Act. Upon reconstruction, an affected source, or a stationary source that becomes an affected source, is subject to MACT standards for new sources, including compliance dates, irrespective of any change in emissions of hazardous air pollutants from that source.

"Research or laboratory activities" means activities whose primary purpose is to conduct research and development into new processes and products where such activities are operated under the close supervision of technically trained personnel and are not engaged in the manufacture of products for commercial sale in commerce, except in a de minimis manner, and where the source is not in a source category, specifically addressing research or laboratory activities, that is listed pursuant to § 112(c)(7) of the federal Clean Air Act.

"Section 112(j) deadline" or "§ 112(j) deadline" means the date 18 months after the date by which a MACT standard is scheduled to be promulgated under 40 CFR Part 63, except that for all major sources listed in the source category schedule for which a MACT standard is scheduled to be promulgated by November 15, 1994, the § 112(j) deadline is November 15, 1996, and for all major sources listed in the source category schedule for which a MACT standard is scheduled to be promulgated by November 15, 1997, the § 112(j) deadline is December 15, 1999.

"Similar source" means that equipment or collection of equipment that, by virtue of its structure, operability, type of emissions and volume and concentration of emissions, is substantially equivalent to the new affected source and employs control technology for control of emissions of hazardous air pollutants that is practical for use on the new affected source.

"Source category schedule for standards" means the schedule issued pursuant to § 112(e) of the federal Clean Air Act for promulgating MACT standards issued pursuant to § 112(d) of the federal Clean Air Act and published in the Federal Register at 67 FR 6521, February 12, 2002.

Statutory Authority

§ 10.1-1308 of the Code of Virginia; §§ 110, 111, 123, 129, 171, 172, and 182 of the Clean Air Act; 40 CFR Parts 51 and 60.

Historical Notes

9VAC5-60-140. Approval process for new and existing affected sources.

A. The requirements of subdivisions 1 and 2 of this subsection apply to major sources that include, as of the § 112(j) deadline, one or more sources in a category or subcategory for which the administrator has failed to promulgate an emission standard under 40 CFR Part 63 on or before an applicable § 112(j) deadline. Existing source MACT requirements (including relevant compliance deadlines), as specified in a federal operating permit issued to the source pursuant to the requirements of this article, shall apply to such sources.

1. The owner shall submit an application for a federal operating permit or for a revision to an existing federal operating permit or a pending federal operating permit meeting the requirements of 9VAC5-60-150 A by the § 112(j) deadline if the owner can reasonably determine that one or more sources at the major source belong in the category or subcategory subject to this article.

2. If an application was not submitted under subdivision A 1 of this section and if notified by the board, the owner shall submit an application for a federal operating permit or for a revision to an existing federal operating permit or a pending federal operating permit meeting the requirements of 9VAC5-60-150 A within 30 days after being notified in writing by the board that one or more sources at the major source belong to such category or subcategory.

3. The requirements in this subdivision apply when the owner has obtained a federal operating permit that incorporates a case-by-case MACT determination by the board under the hazardous air pollutant new source review program or has submitted a federal operating permit application for a revision that incorporates a case-by-case MACT determination under the hazardous air pollutant new source review program, but has not submitted an application for a federal operating permit revision that addresses the emission limitation requirements of this article.

a. When the owner has a federal operating permit that incorporates a case-by-case MACT determination by the board under the hazardous air pollutant new source review program, the owner shall submit an application meeting the requirements of 9VAC5-60-150 A for a federal operating permit revision within 30 days of the § 112(j) deadline or within 30 days of being notified in writing by the board that one or more sources at the major source belong in such category or subcategory. Using the procedures established in subsection E of this section, the board will determine whether the emission limitations prescribed pursuant to the prior case-by-case MACT determination under the hazardous air pollutant new source review program are substantially as effective as the emission limitations which the board would otherwise prescribe pursuant to this article for the source in question. If the board determines that the emission limitations previously prescribed to effectuate the hazardous air pollutant new source review program are substantially as effective as the emission limitations that the board would otherwise prescribe to effectuate this article for the source, then the board will retain the existing emission limitations in the permit as the emission limitations to effectuate this article. The federal operating permit applicable to that source shall be revised accordingly. If the board does not retain the existing emission limitations in the permit as the emission limitations to effectuate this article, the MACT requirements of this article are satisfied upon issuance of a revised federal operating permit incorporating any additional requirements of this article.

b. When the owner has submitted a federal operating permit application that incorporates a case-by-case MACT determination by the board under the hazardous air pollutant new source review program, but has not received the permit incorporating the hazardous air pollutant new source review program requirements, the owner shall continue to pursue a federal operating permit that addresses the emission limitation requirements of the hazardous air pollutant new source review program. Within 30 days of issuance of that federal operating permit, the owner shall submit an application meeting the requirements of 9VAC5-60-150 A for a change to the existing federal operating permit. Using the procedures established in subsection E of this section, the board will determine whether the emission limitations prescribed pursuant to the prior case-by-case MACT determination under the hazardous air pollutant new source review program are substantially as effective as the emission limitations that the board would otherwise prescribe pursuant to this article for the source in question. If the board determines that the emission limitations previously prescribed to effectuate the hazardous air pollutant new source review program are substantially as effective as the emission limitations that the board would otherwise prescribe to effectuate this article for the source, then the board will retain the existing emission limitations in the permit as the emission limitations to effectuate this article. The federal operating permit applicable to that source shall be revised accordingly. If the board does not retain the existing emission limitations in the permit as the emission limitations to effectuate this article, the MACT requirements of this article are satisfied upon issuance of a revised federal operating permit incorporating any additional requirements of this article.

B. The requirements of this subsection apply to sources that do not meet the criteria in subsection A of this section on the § 112(j) deadline and are, therefore, not subject to this article on that date, but where events occur subsequent to the § 112(j) deadline that would bring the source under the requirements of this article, and the source does not have a federal operating permit that addresses the requirements of this article.

1. When one or more sources in a category or subcategory subject to the requirements of this article are installed at a major source, or result in the source becoming a major source due to the installation, and the installation does not invoke the hazardous air pollutant new source review program requirements, the owner shall submit an application meeting the requirements of 9VAC5-60-150 A within 30 days of startup of the source. This application shall be reviewed using the procedures established in subsection E of this section. Existing source MACT requirements (including relevant compliance deadlines), as specified in a federal operating permit issued pursuant to the requirements of this article, shall apply to such sources.

2. The requirements in this subdivision apply when one or more sources in a category or subcategory subject to this article are installed at a major source, or result in the source becoming a major source due to the installation, and the installation does require emission limitations to be established and permitted under the hazardous air pollutant new source review program, and the owner has not submitted an application for a federal operating permit revision that addresses the emission limitation requirements of this article. In this case, the owner shall apply for and obtain a federal operating permit that addresses the emission limitation requirements of the hazardous air pollutant new source review program. Within 30 days of issuance of that federal operating permit, the owner shall submit an application meeting the requirements of 9VAC5-60-150 A for a revision to the existing federal operating permit. Using the procedures established in subsection E of this section, the board will determine whether the emission limitations prescribed pursuant to the prior case-by-case MACT determination under the hazardous air pollutant new source review program are substantially as effective as the emission limitations that the board would otherwise prescribe pursuant to this article for the source in question. If the board determines that the emission limitations previously prescribed to effectuate the hazardous air pollutant new source review program are substantially as effective as the emission limitations that the board would otherwise prescribe to effectuate this article for the source, then the board will retain the existing emission limitations in the permit as the emission limitations to effectuate this article. The federal operating permit applicable to that source shall be revised accordingly. If the board does not retain the existing emission limitations in the permit as the emission limitations to effectuate this article, the MACT requirements of this article are satisfied upon issuance of a revised federal operating permit incorporating any additional requirements of this article.

3. The owner of an area source that, due to a relaxation in any federally enforceable emission limitation (such as a restriction on hours of operation), increases its potential to emit hazardous air pollutants such that the source becomes a major source that is subject to this article, shall submit an application meeting the requirements of 9VAC5-60-150 A for a federal operating permit or for an application for a federal operating permit revision within 30 days after the date that such source becomes a major source. This application shall be reviewed using the procedures established in subsection E of this section. Existing source MACT requirements (including relevant compliance deadlines), as specified in a federal operating permit issued pursuant to the requirements of this article, shall apply to such sources.

4. After December 1, 2002, if the administrator establishes a lesser quantity emission rate under § 112(a)(1) of the federal Clean Air Act that results in an area source becoming a major source that is subject to this article, then the owner of such a major source shall submit an application meeting the requirements of 9VAC5-60-150 A for a federal operating permit or for a change to an existing federal operating permit or pending federal operating permit on or before the date six months after the date that such source becomes a major source. Existing source MACT requirements (including relevant compliance deadlines), as specified in a federal operating permit issued pursuant to the requirements of this article, shall apply to such sources.

C. The requirements of this subsection apply to major sources that include one or more sources in a category or subcategory for which the administrator fails to promulgate an emission standard under 40 CFR Part 63 on or before an applicable § 112(j) deadline, and the owner has a permit meeting the requirements of this article, and where changes occur at the major source to equipment, activities, or both, subsequent to the § 112(j) deadline.

1. If the federal operating permit already provides the appropriate requirements that address the events that occur under this subsection subsequent to the § 112(j) deadline, then the source shall comply with the applicable new source MACT or existing source MACT requirements as specified in the permit, and the requirements of this article are thus satisfied.

2. If the federal operating permit does not contain the appropriate requirements that address the events that occur under this subsection subsequent to the § 112(j) deadline, then the owner shall submit an application for a revision to the existing federal operating permit that meets the requirements of 9VAC5-60-150 A. The application shall be submitted within 30 days of beginning construction and shall be reviewed using the procedures established in subsection E of this section. Existing source MACT requirements (including relevant compliance deadlines), as specified in a federal operating permit issued pursuant to the requirements of this article, shall apply to such sources.

D. Provisions concerning requests for applicability determination for MNSR permits are as follows:

1. An owner who is unsure of whether one or more sources at a major source belong in a category or subcategory for which the administrator has failed to promulgate an emission standard under 40 CFR Part 63 may, on or before an applicable § 112(j) deadline, request an applicability determination from the board by submitting an application meeting the requirements of 9VAC5-60-150 A by the applicable deadlines specified in subsection A, B, or C of this section.

2. In addition to meeting the requirements of subsections A, B, and C of this section, the owner of a new affected source may submit an application for a MNSR permit before construction, pursuant to 9VAC5-60-160.

E. Provisions concerning permit application review are as follows:

1. Each owner who is required to submit to the board a Part 1 MACT application that meets the requirements of 9VAC5-60-150 A for one or more sources in a category or subcategory subject to § 112(j) of the federal Clean Air Act shall also submit to the board a timely Part 2 MACT application for the same sources that meets the requirements of 9VAC5-60-150 B. Each owner shall submit the Part 2 MACT application for the sources in a particular category or subcategory no later than the applicable date specified in Table 6-3A. The submission date specified in Table 6-3A for Miscellaneous Organic Chemical Manufacturing shall apply to sources in each of the source categories listed in Table 6-3B. When the owner is required by this article to submit an application meeting the requirements of 9VAC5-60-150 A by a date that is after the date for a Part 2 MACT application for sources in the category or subcategory in question established by Table 6-3A, the owner shall submit a Part 2 MACT application meeting the requirements of 9VAC5-60-150 B within 60 additional days after the applicable deadline for submission of the Part 1 MACT application. Part 2 MACT applications will be reviewed by the board according to procedures established in 9VAC5-60-170. The resulting MACT determination will be incorporated into the source's federal operating permit according to procedures established under the federal operating permit program and any other regulations approved under the federal operating permit program.

2. Notwithstanding subdivision 1 of this subsection, the owner may request either an applicability determination or an equivalency determination by the board as provided in subdivisions 2 a and b of this subsection.

a. Each owner who submitted a request for an applicability determination pursuant to subdivision D 1 of this section on or before May 15, 2002, which remains pending before the board on March 29, 2004, and who still wishes to obtain such a determination, shall resubmit that request by July 1, 2004, or by the date which is 60 days after the administrator publishes in the Federal Register a proposed emission standard for the category or subcategory in question, whichever is later. Each request for an applicability determination that is resubmitted under this subdivision shall be supplemented to discuss the relation between the sources in question and the applicability provision in the proposed emission standard for the category or subcategory in question, and to explain why there may still be uncertainties that require a determination of applicability. The board will take action upon each properly resubmitted and supplemented request for an applicability determination within an additional 60 days after the applicable deadline for the resubmitted request. If the applicability determination is positive, the owner shall submit a Part 2 MACT application meeting the requirements of 9VAC5-60-150 B by the date specified for the category or subcategory in question in Table 6-3A. If the applicability determination is negative, then no further action by the owner is necessary.

b. As specified in subsections A and B of this section, an owner who has submitted an application meeting the requirements of 9VAC5-60-150 A may request a determination by the board of whether emission limitations adopted pursuant to a prior case-by-case MACT determination under the hazardous air pollutant new source review program that apply to one or more sources at a major source in a relevant category or subcategory are substantially as effective as the emission limitations that the board would otherwise adopt pursuant to § 112(j) of the federal Clean Air Act for the source in question. Such a request shall be submitted by the date for the category or subcategory in question specified in Table 6-3A. Any owner who previously submitted such a request under a prior version of this subdivision need not resubmit the request. Each request for an equivalency determination under this subdivision, regardless of when it was submitted, will be construed in the alternative as a complete application for an equivalent emission limitation under § 112(j) of the federal Clean Air Act. The process for determination by the board of whether the emission limitations in the prior case-by-case MACT determination are substantially as effective as the emission limitations that the board would otherwise adopt under § 112(j) of the federal Clean Air Act will include the opportunity for full public, EPA, and affected state review prior to a final determination. If the board determines that the emission limitations in the prior case-by-case MACT determination are substantially as effective as the emission limitations that the board would otherwise adopt under § 112(j) of the federal Clean Air Act, then the board will adopt the existing emission limitations in the permit as the emission limitations to effectuate § 112(j) of the federal Clean Air Act for the source in question. If more than three years remain on the current federal operating permit, the owner shall submit an application for a federal operating permit revision to make any conforming changes in the permit required to adopt the existing emission limitations as the § 112(j) of the federal Clean Air Act MACT emission limitations. If less than three years remain on the current federal operating permit, any required conforming changes will be made when the permit is renewed. If the board determines that the emission limitations in the prior case-by-case MACT determination under the hazardous air pollutant new source review program are not substantially as effective as the emission limitations that the board would otherwise adopt for the source in question under § 112(j) of the federal Clean Air Act, the board will make a new MACT determination and adopt a federal operating permit incorporating an appropriate equivalent emission limitation under § 112(j) of the federal Clean Air Act. Such a determination constitutes final action for purposes of judicial review under the federal operating permit program provisions.

3. Within 60 days of submittal of the Part 2 MACT application, the board will notify the owner in writing whether the application is complete or incomplete. The Part 2 MACT application shall be deemed complete on the date it was submitted unless the board notifies the owner in writing within 60 days of the submittal that the Part 2 MACT application is incomplete. A Part 2 MACT application is complete if it is sufficient to begin processing the application for a federal operating permit addressing the requirements of this article. In the event that the board disapproves a permit application or determines that the application is incomplete, the owner shall revise and resubmit the application to meet the objections of the board. The board will specify a reasonable period in which the owner is required to remedy the deficiencies in the disapproved or incomplete application. This period may not exceed six months from the date the owner is first notified that the application has been disapproved or is incomplete.

4. Following submittal of a Part 1 or Part 2 MACT application, the board may request additional information from the owner. The owner shall respond to such requests in a timely manner.

5. If the owner has submitted a timely and complete application as required by this section, any failure to have a federal operating permit addressing the requirements of this article shall not be a violation of this article, unless the delay in final action is due to the failure of the applicant to submit, in a timely manner, information required or requested to process the application. Once a complete application is submitted, the owner shall not be in violation of the requirement to have a federal operating permit addressing the requirements of this article.

F. The federal operating permit shall contain an equivalent emission limitation (or limitations) for the relevant category or subcategory determined on a case-by-case basis by the board, or, if the applicable criteria in subpart D of 40 CFR Part 63 are met, the federal operating permit may contain an alternative emission limitation. For the purposes of the preceding sentence, early reductions made pursuant to § 112(i)(5)(A) of the federal Clean Air Act shall be achieved not later than the date on which the MACT standard should have been promulgated according to the source category schedule for standards.

1. The federal operating permit shall contain an emission standard or emission limitation that is equivalent to existing source MACT and an emission standard or emission limitation that is equivalent to new source MACT for control of emissions of hazardous air pollutants. The MACT emission standards or limitations shall be determined by the board and shall be based on the degree of emission reductions that can be achieved if the control technologies or work practices are installed, maintained, and operated properly. The permit shall also specify the affected source and the new affected source. If construction of a new affected source or reconstruction of an affected source commences after a federal operating permit meeting the requirements of this article has been issued for the source, the new source MACT compliance dates shall apply.

2. The federal operating permit shall specify any notification, operation and maintenance, performance testing, monitoring, and reporting and recordkeeping requirements. In developing the federal operating permit, the board will consider and specify the appropriate provisions of subpart A of 40 CFR Part 63. The federal operating permit shall also include the information in subdivisions 2 a through c of this subsection.

a. In addition to the MACT emission limitation required by subdivision F 1 of this section, additional emission limits, production limits, operational limits or other terms and conditions necessary to ensure practicable enforceability of the MACT emission limitation;

b. Compliance certifications, testing, monitoring, reporting and recordkeeping requirements that are consistent with requirements established pursuant to the federal operating permit program and subsection H of this section; and

c. Compliance dates by which the owner shall be in compliance with the MACT emission limitation and all other applicable terms and conditions of the permit.

(1) The owner of an affected source subject to the requirements of this subdivision shall comply with the emission limitations by the date established in the source's federal operating permit. In no case shall such compliance date be later than three years after the issuance of the permit for that source, except where the board issues a permit that grants an additional year to comply in accordance with § 112(i)(3)(B) of the federal Clean Air Act, or unless otherwise specified in § 112(i) of the federal Clean Air Act, or in subpart D of 40 CFR Part 63.

(2) The owner of a new affected source, as defined in the federal operating permit meeting the requirements of this article, that is subject to the requirements of this article shall comply with a new source MACT level of control immediately upon startup of the new affected source.

G. The board will issue a federal operating permit meeting the requirements of this article within 18 months after submittal of the complete Part 2 MACT application.

H. In accordance with § 114(a)(3) of the federal Clean Air Act, monitoring shall be capable of demonstrating continuous compliance for each compliance period during the applicable reporting period. Such monitoring data shall be of sufficient quality to be used as a basis for directly enforcing all applicable requirements established under this article, including emission limitations.

I. Provisions concerning MACT emission limitations are as follows:

1. The owner of affected sources subject to subsections A, B, and C of this section shall comply with all requirements of this article that are applicable to affected sources, including the compliance date for affected sources established in subdivision F 2 c (1) of this section.

2. The owner of new affected sources subject to subdivision C 1 of this section shall comply with all requirements of this article that are applicable to new affected sources, including the compliance date for new affected sources established in subdivision F 2 c (2) of this section.

Historical Notes

9VAC5-60-150. Application content for case-by-case MACT determinations.

A. The Part 1 application for a case-by-case MACT determination shall contain the following information:

1. The name and address (physical location) of the major source;

2. A brief description of the major source and an identification of the relevant source category;

3. An identification of the types of emissions points belonging to the relevant source category; and

4. An identification of any affected sources for which a hazardous air pollutant new source review program MACT determination has been made.

B. The following provisions govern the Part 2 application for a case-by-case MACT determination:

1. In compiling a Part 2 MACT application, the owner may cross-reference specific information in any prior submission by the owner to the board, but in cross-referencing such information the owner may not presume favorable action on any prior application or request that is still pending. In compiling a Part 2 MACT application, the owner may also cross-reference any part of a proposed emission standard for any category or subcategory that includes sources to which the Part 2 application applies.

2. The Part 2 application for a MACT determination shall contain the following information:

a. For a new affected source, the anticipated date of startup of operation.

b. Each emission point or group of emission points at the affected source that is part of a category or subcategory for which a Part 2 MACT application is required and each of the hazardous air pollutants emitted at those emission points. When the administrator has proposed an emission standard for a category or subcategory, such information may be limited to those emission points and hazardous air pollutants that would be subject to control under the proposed standard.

c. Any existing federal, state, or local limitations or requirements governing emissions of hazardous air pollutants from those emission points that are part of a category or subcategory for which a Part 2 application is required.

d. For each identified emission point or group of affected emission points, an identification of control technology in place.

e. Any additional emission data or other information specifically requested by the board.

C. The Part 2 application for a MACT determination may, but is not required to, contain the following information:

1. Recommended emission limitations for the affected source and support information consistent with 40 CFR 63.52(f). The owner may recommend a specific design, equipment, work practice, or operational standard, or combination thereof, as an emission limitation;

2. A description of the control technologies that shall apply to meet the emission limitations including technical information on the design, operation, size, estimated control efficiency, and any other information deemed appropriate by the board, and identification of the affected sources to which the control technologies shall be applied; and

3. Relevant parameters to be monitored and frequency of monitoring to demonstrate continuous compliance with the MACT emission limitation over the applicable reporting period.

Historical Notes

9VAC5-60-160. Preconstruction review procedures for new affected sources subject to 9VAC5-60-140 C 1.

A. The review process for new affected sources is as follows:

1. If the board requires an owner to obtain or revise a federal operating permit before construction of the new affected source, or when the owner chooses to obtain or revise a federal operating permit before construction, the owner shall follow the administrative procedures established under the federal operating permit program before construction of the new affected source.

2. If an owner is not required to obtain or revise a federal operating permit before construction of the new affected source (and has not elected to do so), but the new affected source is covered by any preconstruction or pre-operation review requirements established pursuant to the hazardous air pollutant new source review program, then the owner shall comply with those requirements. If the new affected source is not subject to the hazardous air pollutant new source review program, the board will issue a MNSR permit in accordance with the MNSR permit procedures supplemented by the procedures set forth in subsections B through H of this section before construction or operation of the new affected source.

3. Regardless of the review process, the case-by-case MACT determination will be consistent with the principles established in 9VAC5-60-170. The application for the applicable new source review permit or a federal operating permit, permit modification, or administrative amendment, whichever is applicable, will include the documentation required by 9VAC5-60-150.

B. The board will provide for an enhanced review of MNSR permits used to implement case-by-case MACT determinations in accordance with the following review procedures and compliance requirements:

1. The board will notify the owner in writing as to whether the application for a case-by-case MACT determination is complete or whether additional information is required.

2. The board will approve an applicant's proposed control technology, or the board will notify the owner in writing of its intention to disapprove a control technology.

3. The owner may present in writing, within a time frame specified by the board, additional information, considerations, or amendments to the application before the board's issuance of a final disapproval.

4. The board will issue a preliminary approval or issue a disapproval of the application taking into account additional information received from the owner.

5. A determination to disapprove any application will be in writing and will specify the grounds on which the disapproval is based.

6. Approval of an applicant's proposed control technology will be set forth in a MNSR permit as described in 9VAC5-60-140 F.

C. The board will provide opportunity for public comment on the preliminary MNSR permit prior to issuance, including, at a minimum:

1. Availability for public inspection, in at least one location in the area affected, of the information submitted by the owner and of the board's tentative determination;

2. A period for submittal of public comment of at least 30 days;

3. A notice by prominent advertisement in the area affected of the location of the source information and analysis specified in 9VAC5-60-140 F. The form and content of the notice will be substantially equivalent to that found in 9VAC5-80-270 or 9VAC5-80-670; and

4. An opportunity for a public hearing if one is requested. The board will give at least 30 days' notice in advance of any hearing.

D. The board will send copies of the preliminary permit (in time for comment) and final permit required by subsection C of this section to the administrator through the appropriate regional office, to affected states, and to all other state and local air pollution control agencies having jurisdiction in the region in which the new source would be located. The board will provide EPA with a review period for the final permit of at least 45 days, and will not issue the final MNSR permit until EPA objections are satisfied.

E. An owner of a major source that is subject to a case-by-case MACT determination shall comply with notification, operation and maintenance, performance testing, monitoring, reporting, and recordkeeping requirements established under 9VAC5-60-140 F 2, under the federal operating permit program, and at the discretion of the board, under Subpart A of 40 CFR Part 63. The board will provide the EPA with the opportunity to review compliance requirements for consistency with requirements established pursuant to the federal operating permit program during the review period under subsection D of this section.

F. If the board requires a new source review permit for a new source case-by-case MACT determination under this article, such requirement will not necessitate a determination under Subpart E of 40 CFR Part 63.

Historical Notes

9VAC5-60-170. Maximum achievable control technology (MACT) determinations for affected sources subject to case-by-case determination of equivalent emission ....

A. The board will determine whether the Part 1 and Part 2 MACT application is complete or an application for a MNSR permit is approvable. In either case, when the application is complete or approvable, the board will establish hazardous air pollutant emissions limitations equivalent to the limitations that would apply if an emission standard had been issued in a timely manner under § 112(d) or (h) of the federal Clean Air Act. The board will establish these emissions limitations consistent with the following requirements and principles:

1. Emission limitations will be established for the equipment and activities within the affected sources within a source category or subcategory for which the deadline in § 112(j) of the federal Clean Air Act has passed.

2. Each emission limitation for an existing affected source will reflect the maximum degree of reduction in emissions of hazardous air pollutants (including a prohibition on such emissions, where achievable) that the board, taking into consideration the cost of achieving such emission reduction and any nonair quality health and environmental impacts and energy requirements, determines is achievable by affected sources in the category or subcategory for which the deadline in § 112(j) of the federal Clean Air Act has passed. This limitation will not be less stringent than the MACT floor, which will be established by the board according to the requirements of § 112(d)(3)(A) and (B) of the federal Clean Air Act and will be based upon available information.

3. Each emission limitation for a new affected source will reflect the maximum degree of reduction in emissions of hazardous air pollutants (including a prohibition on such emissions, where achievable) that the board, taking into consideration the cost of achieving such emission reduction and any nonair quality health and environmental impacts and energy requirements, determines is achievable. This limitation will not be less stringent than the emission limitation achieved in practice by the best controlled similar source that will be established by the board according to the requirements of § 112(d)(3) of the federal Clean Air Act. This limitation will be based upon available information.

4. The board will select a specific design, equipment, work practice, or operational standard, or combination thereof, when it is not feasible to prescribe or enforce an equivalent emission limitation due to the nature of the process or pollutant. It is not feasible to prescribe or enforce a limitation when the administrator determines that hazardous air pollutants cannot be emitted through a conveyance designed and constructed to capture such pollutant, or that any requirement for, or use of, such a conveyance would be inconsistent with any federal, state, or local law, or the application of measurement methodology to a particular class of sources is not practicable due to technological and economic limitations.

5. Nothing in this article will prevent the board from establishing an emission limitation more stringent than required by federal regulations.

B. The owner shall submit additional copies of its Part 1 and Part 2 MACT application for a federal operating permit, permit revision, or MNSR permit, whichever is applicable, to the EPA at the same time the material is submitted to the board.

9VAC5-60-180. Requirements for case-by-case determination of equivalent emission limitations after promulgation of a subsequent MACT standard.

A. If the administrator promulgates a MACT standard that is applicable to one or more affected source within a major source before the date a federal operating permit application under this subsection is approved, the permit will contain the promulgated standard rather than the emission limitation determined under 9VAC5-60-140, and the owner shall comply with the promulgated standard by the compliance date in the promulgated standard.

B. If the administrator promulgates a MACT standard under § 112(d) or § 112(h) of the federal Clean Air Act that is applicable to a source after the date a federal operating permit is issued pursuant to 9VAC5-60-140 or 9VAC5-60-160, the board will incorporate requirements of that standard in the permit upon its next renewal. The board will establish a compliance date in the revised federal operating permit that assures that the owner shall comply with the promulgated standard within a reasonable time, but not longer than eight years after such standard is promulgated or eight years after the date by which the owner was first required to comply with the emission limitation established by the federal operating permit, whichever is earlier. However, in no event will the period for compliance for existing sources be shorter than that provided for existing sources in the promulgated standard.

C. Notwithstanding the requirements of subsections A and B of this section, the requirements of subdivisions 1 and 2 of this subsection apply.

1. If the administrator promulgates a MACT standard under § 112(d) or (h) of the federal Clean Air Act that is applicable to an affected source after the date a federal operating permit application is approved under 9VAC5-60-140 or 9VAC5-60-160, the board is not required to change the emission limitation in the federal operating permit to reflect the promulgated standard if the board determines that the level of control required by the emission limitation in the federal operating permit is substantially as effective as that required by the promulgated standard pursuant to 40 CFR 63.1(e).

2. If the administrator promulgates an emission standard under § 112(d) or (h) of the federal Clean Air Act that is applicable to an affected source after the date a permit application is approved under 9VAC5-60-140 or 9VAC5-60-160, and the level of control required by the promulgated standard is less stringent than the level of control required by any emission limitation in the prior MACT determination, the board is not required to incorporate any less stringent emission limitation of the promulgated standard in the federal operating permit and may in its discretion consider any more stringent provisions of the MACT determination to be applicable legal requirements when issuing or revising such a federal operating permit.

Article 4
Emission Standards for Toxic Pollutants from Existing Sources (Rule 6-4)

9VAC5-60-200. Applicability and designation of affected facility.

Article 4
Emission Standards for Toxic Pollutants from Existing Sources (Rule 6-4)

A. Except as provided in subsections C, D, and E of this section, the affected facility to which the provisions of this article apply is each stationary source that emits or may emit any toxic pollutant and which is not subject to Article 5 (9VAC5-60-300 et seq.) of this part. Implementation of this article shall occur upon notification to the owner by the board through means such as an information request from the board or an operating permit review under Article 5 (9VAC5-80-800 et seq.) of Part II of 9VAC5 Chapter 80.

B. The provisions of this article apply throughout the Commonwealth of Virginia.

C. This article shall not apply to the following:

1. A stationary source that has a potential to emit a toxic pollutant with a TLV® at a level equal to or less than the exemption emission rate calculated using the exemption formulas set forth below for the applicable TLV®. If more than one exemption formula applies to a toxic pollutant emitted by a source, the potential to emit for that pollutant shall be equal to or less than both applicable exemption formulas in order for the source to be exempted for that pollutant. The exemption formulas apply on an individual basis to each toxic pollutant for which a TLV® has been established.

a. For toxic pollutants with a TLV-C®, the following exemption formula applies, provided the potential to emit does not exceed 22.8 pounds per hour:

Exempt Emission Rate (pounds per hour) = TLV-C® (mg/m³) x 0.033

b. For toxic pollutants with both a TLV-STEL® and a TLV-TWA®, the following exemption formulas apply, provided the potential to emit does not exceed 22.8 pounds per hour or 100 tons per year:

Exempt Emission Rate (pounds per hour) = TLV-STEL® (mg/m³) x 0.033

Exempt Emission Rate (tons per year) = TLV-TWA® (mg/m³) x 0.145

c. For toxic pollutants with only a TLV-TWA®, the following exemption formulas apply, provided the potential to emit does not exceed 22.8 pounds per hour or 100 tons per year:

Exempt Emission Rate (pounds per hour) = TLV-TWA® (mg/m³) x 0.066

Exempt Emission Rate (tons per year) = TLV-TWA® (mg/m³) x 0.145

2. A stationary source that has a potential to emit a toxic pollutant without a TLV® if, upon the owner's request, the board determines to exempt that toxic pollutant from the provisions of this article using available health effects information.

The exemption determination shall be made by the board using information submitted by the owner at the request of the board as set out in 9VAC5-60-240.

3. A stationary source subject to an emission standard or other requirement set forth in Article 2 (9VAC5-60-10 et seq.) of this part. If less than all of the stationary source is regulated by such an emission standard or other requirement, then only that part of the stationary source regulated by the emission standard or other requirement is exempted.

4. A stationary source in a source category that is regulated by an emission standard or other requirement established pursuant to § 112 of the federal Clean Air Act and subject to the source category schedule for standards. If less than all of the stationary source is in a source category that is regulated by such an emission standard or other requirement, then only that part of the stationary source in the source category regulated by the emission standard or other requirement is exempted.

5. A stationary source in a source category for which the U.S. Environmental Protection Agency has made a formal determination that no regulations or other requirements need to be established pursuant to § 112 of the federal Clean Air Act and has published the determination in the source category schedule for standards.

6. A boiler, incinerator, or industrial furnace as defined in 40 CFR 260.10 and subject to 9VAC20 Chapter 60 (9VAC20-60), provided it (i) meets the 99.99% destruction and removal efficiency standard required by 9VAC20 Chapter 60 (9VAC20-60), and (ii) has received a permit or has qualified for interim status in accordance with 9VAC20 Chapter 60 (9VAC20-60). The board shall be furnished with an acceptable certification that such boiler, incinerator, or industrial furnace is in compliance with the standards of its permit or interim status and applicable provisions of 9VAC20 Chapter 60 (9VAC20-60). Unless exempted under 9VAC5-60-200 C 4, facilities that burn hazardous waste for energy recovery are subject to this article.

7. A generator or boiler that burns only natural gas, #2 fuel oil, #4 fuel oil, #6 fuel oil, propane, or kerosene.

D. Provisions of this article do not apply to any consumer product used in the same manner as normal consumer use, provided the use results in a duration and frequency of exposure which is not greater than exposures experienced by consumers. This may include, but not be limited to, personal use items, janitorial cleaning supplies, and facility grounds maintenance products, such as fertilizers, pesticides, and paints for structural components.

E. With regard to the application of pesticides, the provisions of this article shall apply only to the air quality impact from emissions from application inside the premises of the following affected facilities:

1. Industrial and manufacturing operations, including warehouse and storage operations related to the operation of these facilities.

2. Warehouse and storage operations at transportation terminals.

The provisions of this article shall not apply to the air quality impact from emissions from the application of any pesticide outside.

F. No provision of this article shall limit the power of the board to apply the provisions of this article to any affected facility in order to prevent or remedy a condition that may cause or contribute to the endangerment of human health.

9VAC5-60-210. Definitions.

A. For the purpose of the Regulations for the Control and Abatement of Air Pollution and subsequent amendments or any orders issued by the board, the words or terms shall have the meanings given them in subsection C of this section.

B. As used in this article, all terms not defined here shall have the meanings given them in 9VAC5 Chapter 10 (9VAC5-10-10 et seq.), unless otherwise required by context.

C. Terms defined.

"Fugitive emissions" means those emissions that could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening.

"Pesticide" means the same as the definition given in § 3.1-249.27 of the Virginia Pesticide Control Act.

"Potential to emit" means an emission rate based on the maximum capacity of a stationary source to emit a toxic pollutant under its physical and operational design. Any physical or operational limitation on the capacity of the source to emit a toxic pollutant, including air pollution control equipment, and restrictions on hours of operation or on the type or amount of material combusted, stored, or processed, shall be treated as part of its design only if the limitation or its effect on emissions is state or federally enforceable. Fugitive emissions shall be included in determining a stationary source's potential to emit.

"Significant ambient air concentration" means the concentration of a toxic pollutant in the ambient air that if exceeded may have the potential to injure human health.

"Threshold limit value (TLV®)" means the maximum airborne concentration of a substance to which the American Conference of Governmental Industrial Hygienists (ACGIH) believes that nearly all workers may be repeatedly exposed day after day without adverse effects and which is published in the ACGIH Handbook (see 9VAC5-20-21). The TLV® is divided into three categories: TLV-Time-Weighted Average® (TLV-TWA®), TLV-Short-Term Exposure Limit® (TLV-STEL®), and TLV-Ceiling® (TLV-C®).

"TLV-TWA®" means the time-weighted average concentration for a normal eight-hour workday and a 40-hour workweek, to which nearly all workers may be repeatedly exposed, day after day, without adverse effect (as defined in the ACGIH Handbook).

"TLV-STEL®" means the concentration to which workers may be exposed continuously for a short period of time without suffering from irritation, chronic or irreversible tissue damage, or narcosis of sufficient degree to increase the likelihood of accidental injury, impair self-rescue or materially reduce work efficiency. The TLV-STEL® supplements the TLV-TWA® where there are recognized acute effects from a substance whose toxic effects are primarily of a chronic nature.

"TLV-C®" means the concentration that should not be exceeded during any part of the working exposure.

"Toxic pollutant" means any air pollutant listed in § 112(b) of the federal Clean Air Act, as revised by 40 CFR 63.60, or any other air pollutant that the board determines, through adoption of regulation, to present a significant risk to public health. This term excludes asbestos, fine mineral fibers, radionuclides, and any glycol ether that does not have a TLV®.

Historical Notes

9VAC5-60-220. Standard for toxic pollutants.

If a stationary source is not exempt under 9VAC5-60-200 C, D, or E, then the following standards shall be met:

1. Regardless of any provision of any other regulation of the board, no owner or other person shall cause or permit to be discharged into the atmosphere from any affected facility any emissions of toxic pollutants in such quantities as to cause, or contribute to, any significant ambient air concentration that may cause, or contribute to, the endangerment of human health.

2. The owner of an affected facility shall employ control strategies as may be directed by the board for the control of toxic pollutants. The board may consider the potency and toxicity of each regulated toxic pollutant as well as the technical and economic feasibility of any available control strategies. Possible control strategies may include but are not limited to emission control equipment, process changes, substitution of less toxic or nontoxic materials, or operation and maintenance procedures which lower or eliminate emissions of toxic pollutants.

Historical Notes

9VAC5-60-230. Significant ambient air concentration guidelines.

For the purpose of case-by-case consideration between the board and the owner, significant ambient air concentrations are any of the following:

1. For pollutants with a TLV-C®, any one-hour concentration of a toxic pollutant in excess of 1/40 of the TLV-C®.

2. For pollutants with both a TLV-STEL® and a TLV-TWA®, any one-hour concentration of a toxic pollutant in excess of 1/40 of the TLV-STEL® and any annual concentration of a toxic pollutant in excess of 1/500 of the TLV-TWA®.

3. For pollutants with only a TLV-TWA®, any annual concentration of a toxic pollutant in excess of 1/500 of the TLV-TWA® and any one-hour concentration of a toxic pollutant in excess of 1® of the TLV-TWA®.

4. Any concentration resulting from the emissions of a toxic pollutant from an affected facility which the owner knows, or reasonably should be expected to know, may cause, or contribute to, the endangerment of human health.

5. Any concentration, other than those specified in subdivision 1, 2, 3, or 4 of this section, including those resulting from toxic pollutants not having a TLV®, which the board determines to cause, to have the potential to cause, or to contribute to, the endangerment of human health. This determination shall be made by considering information by recognized authorities on the specific health effects of such toxic pollutants.

9VAC5-60-260. Compliance.

A. If the board has reason to believe that the emissions from an affected facility are, or may be, discharged in such quantities so as to cause, or contribute to, any ambient air concentration that is (i) in excess of any significant ambient air concentration specified in 9VAC5-60-230 or (ii) has the potential to cause or contribute to substantial and imminent endangerment of human health, the owner shall choose one or more of the following options and comply with the schedules contained in subsection B of this section.

1. Demonstrate that the emissions from the facility do not, and will not, cause, or contribute to, any of the significant ambient air concentrations in 9VAC5-60-230 being exceeded.

2. Demonstrate that the applicable significant ambient air concentration in 9VAC5-60-230 is inappropriate for the toxic pollutant in question by showing that the emissions from the affected facility produce no endangerment of human health.

3. Control the emissions from the affected facility to a level resulting in ambient air concentrations that are below the significant ambient air concentrations or resulting in such other ambient air concentrations acceptable to the board.

B. The owner shall notify the board of his choice under subsection A of this section within 45 days of notification by the department that his facility exceeds the significant ambient air concentration specified in 9VAC9-60-230. Within 45 days of notifying the board of the option under subsection A of this section, the owner shall submit a plan and schedule to the board for approval. If the owner fails to submit either his choice of an option as set out in subsection A of this section or a plan and schedule to implement that option, the board shall require the owner, on a schedule set out by the board, to comply with subdivision A 3 of this section. None of the times specified in this subsection include time needed for board approval. Reasonable extensions may be granted when deemed appropriate by the board.

C. Failure of the owner to accomplish any of the alternatives set forth in subsection A of this section in a manner acceptable to the board shall constitute a violation of 9VAC5-60-220.

9VAC5-60-270. Public participation.

If the owner of an affected facility chooses the demonstration under 9VAC5-60-260 A 2, the provisions of this section shall apply.

1. Prior to the decision of the board on the acceptability of the demonstration, the demonstration shall be subject to a public comment period of at least 30 days.

2. The board shall notify the public of the opportunity for public comment on the information available for public inspection under the provisions of subdivision 3 of this section. The notification shall be made by advertisement in one newspaper of general circulation in the affected air quality control region and, if available, one newspaper that circulates in the area where the affected facility is located. A copy of the notice shall be sent to the governing body of the locality where the affected facility is located and to the governing bodies of the localities where ambient air quality impacts from the affected facility exceed the significant ambient air concentration guidelines in 9VAC5-60-230. The notice shall include a brief description of the pollutants of concern and their possible impacts, the demonstration, a statement listing the requirements in subdivisions 4 and 5 of this section, and the name and telephone number of a department staff person from whom detailed information on the demonstration and the pollutants may be obtained.

3. Information relevant to the demonstration, including (i) information produced by the owner showing that the emissions from the affected facility do not endanger human health and (ii) the preliminary review, analysis and tentative determination of the board, shall be available for public inspection during the entire comment period in at least one location in the affected air quality control region.

4. Following the initial publication of notice of a public comment period, the board will receive written requests for a public hearing to consider the source's demonstration under 9VAC5-60-260 A 2. The request shall be submitted within 30 days of the appearance of the notice in the newspaper. Request for a public hearing shall contain the following information:

a. The name, mailing address and telephone number of the requester;

b. The names and addresses of all persons for whom the requester is acting as a representative;

c. The reason why a hearing is requested; and

d. A brief, informal statement setting forth the factual nature and the extent of the interest of the requester or of the persons for whom the requester is acting as representative, including an explanation of how and to what extent such interest would be directly and adversely affected by the demonstration in question.

5. The board shall review all timely requests for public hearing filed during the 30 days following the appearance of the public comment notice in the newspaper. Within 30 calendar days following the expiration of the public comment period the board shall grant a public hearing if it finds that one or both of the following apply:

a. There is significant public interest in the demonstration in question.

b. There are substantial, disputed issues relevant to the demonstration in question.

6. The board shall notify by mail the owner making the demonstration and each requester, at his last known address, of the decision to convene or deny a public hearing. The notice shall contain a description of the procedures for the public hearing and for the final determination under this section.

7. If the board decides to hold a public hearing, the hearing shall be scheduled at a time between 30 and 60 days after mailing the notification required by subdivision 6 of this section. The public hearing shall be held in the affected air quality control region.

8. The procedures for notification to the public and availability of information used for the public comment period and provided in subdivisions 2 and 3 of this section shall also be followed for the public hearing.

NOTE: In adopting amendments to this article to be effective May 1, 2002, the board renumbered the sections. In the interest of economy and efficiency, the board did not make the corresponding change at each place the old section numbers occur throughout the Regulations for the Control and Abatement of Air Pollution. However, it is the intent of the board to make that change in other parts of the regulations as the opportunity presents itself. Until such changes are made, the old section numbers (9VAC5-40-160 through 9VAC5-40-230) shall be construed to mean the new section numbers (9VAC5-60-200 through 9VAC5-60-270) throughout the regulations of the board.

9VAC5-60-310. Definitions.

B. As used in this article, all terms not defined here shall have the meanings given them in 9VAC5 Chapter 10 (9VAC5-10), unless otherwise required by context.

C. Terms defined.

"Best available control technology" means an emissions limitation (including a visible emissions standard) based on the maximum degree of reduction for each toxic pollutant which the board, on a case-by-case basis, taking into account energy, environmental, and economic impacts and other costs, determines is achievable for such source or modification through application of production processes or available methods, systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion techniques for control of such pollutant. If the board determines that technological or economic limitations on the application of measurement methodology to a particular emissions unit would make the imposition of an emissions standard infeasible, a design, equipment, work practice, operational standard, or combination of them, may be prescribed instead to satisfy the requirement for the application of best available control technology. Such standard shall, to the degree possible, set forth the emissions reduction achievable by implementation of such design, equipment, work practice or operation, and shall provide for compliance by means which achieve equivalent results.

"Fugitive emissions" means those emissions that could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening.

"Pesticide" means the same as the definition given in § 3.1-249.27 of the Virginia Pesticide Control Act.

"Significant ambient air concentration" means the concentration of a toxic pollutant in the ambient air that if exceeded may have the potential to injure human health.

"TLV-STEL®" means the concentration to which workers may be exposed continuously for a short period of time without suffering from irritation, chronic or irreversible tissue damage, or narcosis of sufficient degree to increase the likelihood of accidental injury, impair self-rescue or materially reduce work efficiency. The TLV-STEL supplements the TLV-TWA® where there are recognized acute effects from a substance whose toxic effects are primarily of a chronic nature.

"TLV-C®" means the concentration that should not be exceeded during any part of the working exposure.
