Current through Register Vol. 40, No. 24, July 15, 2024
"Actual emissions" means the actual emissions of a
					 pollutant from a stationary source or emissions unit reflecting the rate, in
					 tons per year, at which the source or unit actually emitted the pollutant
					 during the most recent annual period. Actual emissions shall be calculated
					 using the source or unit's actual operating hours, in place emission controls,
					 production rates, and types of materials processed, stored, or combusted during
					 the annual period. Valid continuous emission monitoring data or source test
					 data shall be preferentially used to determine actual emissions. In the absence
					 of valid continuous emissions monitoring data or source test data, the basis
					 for determining actual emissions shall be any or all of the following as may be
					 determined by the department: throughputs of process materials; throughputs of
					 materials stored; usage of materials; data provided in manufacturer's product
					 specifications, material volatile organic compound content reports or
					 laboratory analyses; other information required by this chapter and other
					 regulations of the board; or information requested in writing by the
					 department. All calculations of actual emissions shall use U.S. Environmental
					 Protection Agency or department-approved methods, including emission factors
					 and assumptions.
"Annual period" means a period of 12 consecutive months
					 determined on a rolling basis with a new 12-month period beginning on the first
					 day of each calendar month.
"Federal operating permit" means a permit issued pursuant
					 to Article 1 (9VAC5-80-50 et seq.) of Part II of
					 9VAC5 Chapter 80.
"Fugitive dust" means particulate matter composed of soil
					 or other materials, or both, of natural origin. Fugitive dust may include
					 emissions from haul roads, wind erosion of exposed surfaces and storage piles
					 and other activities in which the material is either removed, stored,
					 transported or redistributed.
"Fugitive emissions" means emissions which are generated
					 by industrial or other activities and which do not pass through a stack,
					 chimney, vent or other functionally equivalent opening, but which may escape
					 from openings (such as windows, doors, ill-fitting closures or poorly
					 maintained equipment) or material handling equipment.
"General permit" means the terms and conditions in Part IV
					 (9VAC5-510-170 et seq.) of this
					 chapter that meet the requirements of Part III (9VAC5-510-90 et seq.) of this
					 chapter and issued under the provisions
					 9VAC5-80-1030 and
					 9VAC5-80-1250.
"New source review program" means a program for the
					 preconstruction review and permitting of new stationary sources or emissions
					 units or expansions to existing ones in accordance with regulations 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.
"Nonmetallic mineral" means any of the following minerals
					 or any mixture of which the majority is any of the following minerals:
1. Crushed and broken stone, including
				  limestone, dolomite, granite, traprock, sandstone, quartz, quartzite, marl,
				  marble, slate, shale, oil shale, and shell.
2. Sand and gravel.
3. Clay including kaolin, fireclay,
				  bentonite, fuller's earth, ball clay, and common clay.
4. Rock salt.
5. Gypsum.
6. Sodium compounds, including sodium
				  carbonate, sodium chloride, and sodium sulfate.
7. Pumice.
8. Gilsonite.
9. Talc and pyrophyllite.
10. Boron, including borax, kernite, and
				  colemanite.
11. Barite.
12. Fluorospar.
13. Feldspar.
14. Diatomite.
15. Perlite.
16. Vermiculite.
17. Mica.
18. Kyanite, including andalusite,
				  sillimanite, topaz, and dumortierite.
"Nonmetallic mineral processing facility" means any
					 combination of equipment that is used to crush or grind any nonmetallic mineral
					 wherever located, including lime plants, power plants, steel mills, asphalt
					 concrete plants, portland cement plants, or any other facility processing
					 nonmetallic minerals. Includes activity at facilities where the primary purpose
					 is classified as Standard Industrial Classification (SIC) Code 1411, 1422,
					 1423, 1429, 1442, 1446, 1455, 1459, and 1499 as described in the Standard
					 Industrial Classification Manual (see
					 9VAC5-20-21 ). Includes stationary
					 diesel engines. Also includes activity at facilities classified under other SIC
					 codes that may be colocated within the nonmetallic mineral processing area,
					 unless they are expressly excluded by this chapter.
"Permittee" means the owner of a nonmetallic mineral
					 processing facility covered under this general permit.
"Portable facility" means any nonmetallic mineral
					 processing facility that is mounted on any chassis or skids and may be moved by
					 the application of a lifting or pulling force. In addition, there shall be no
					 cable, chain, turnbuckle, bolt or other means (except electrical connections)
					 by which any piece of equipment is attached or clamped to any anchor, slab, or
					 structure, including bedrock that must be removed prior to the application of a
					 lifting or pulling force for the purpose of transporting the unit.
"Potential to emit" means the maximum capacity of a
					 stationary source to emit any air pollutant under its physical and operational
					 design. Any physical or operational limitation on the capacity of a source to
					 emit an air 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 is state and federally enforceable.
"Relocation" means a change in physical location of a
					 nonmetallic mineral processing facility or an emissions unit from one
					 nonmetallic mineral processing facility to another nonmetallic mineral
					 processing facility.
"Spreadsheet" means the Aggregate Processing Emission
					 Calculation Spreadsheet and the Stationary Diesel Engine Emission Calculation
					 Spreadsheet.
"State operating permit" means a permit issued pursuant to
					 Article 5 (9VAC5-80-800 et seq.) of Part II of
					 9VAC5 Chapter 80.
