				Effective: August 25, 2023 [Comment: For dates and availability of
		non-regulatory government publications, publications of recognized
		organizations and associations, federal rules, and federal statutory provisions
		referenced in this rule, see paragraph (AA) of this rule titled
		"referenced materials."] Except as otherwise provided in this rule, the
		definitions in rule 3745-15-01 of the Administrative Code apply to this
		chapter. As used in this chapter: (A) [Reserved.] (B)   (1) "Banked
			 condition" means the condition where fuel is burned on the grates of fuel
			 burning equipment at rates which are sufficient to maintain ignition
			 only. (2) "British thermal
			 unit" or "Btu" means the amount of heat required to raise the
			 temperature of one pound of water from fifty-nine degrees Fahrenheit to sixty
			 degrees Fahrenheit at a constant pressure of one atmosphere. (C)   (1) "Central heater" means a
			 fuel-burning device designed to burn wood or wood pellet fuel that warms spaces
			 other than the space where the device is located, by the distribution of air
			 heated by the furnace through ducts or liquid heated in the device and
			 distributed typically through pipes. Unless otherwise specified, these devices
			 include, but are not limited to, residential forced-air furnaces (small and
			 large) and residential hydronic heaters. (2) "Chip wood fuel" means wood
			 chipped into small pieces that are uniform in size, shape, moisture, density
			 and energy content. (D) [Reserved.] (E) [Reserved.] (F) [Reserved.] (1) "Facility" means any
			 building, structure, installation, operation, or combination thereof which
			 contains one or more stationary sources of air contaminants. As used in
			 paragraph (D) of rule 3745-17-08 of the Administrative Code, the definition of
			 facility does not include agricultural activities, such as the tilling of land,
			 the harvesting of crops, the application of fertilizers, pesticides or
			 herbicides, and grain drying, which are conducted on a farm. (2) "Fireplace" means a
			 wood-burning appliance intended to be used primarily for aesthetic enjoyment
			 and not as a space heater. An appliance is a fireplace if it is in a model line
			 that satisfies one of the following: (a) The model line includes a safety listing under recognized
				American or Canadian safety standards, as documented by a permanent label from
				a nationally recognized certification body affixed on each unit sold, and that
				said safety listing only allows operation of the fireplace with doors fully
				open. Operation with any required safety screen satisfies this
				requirement. (b) The model line has a safety listing that allows operation
				with doors closed, has no user-operated controls other than flue or outside air
				dampers that can only be adjusted to either a fully closed or fully opened
				position, and either of the following are satisfied: (i) Appliances are sold
				  with tempered glass panel doors only (either as standard or optional
				  equipment). (ii) The fire viewing
				  area is equal to or greater than five hundred square inches. (c) A model line that is clearly positioned in the marketplace as
				intended to be used primarily for aesthetic enjoyment and not as a room heater,
				as demonstrated by product literature (including owner's manuals),
				advertising targeted at the trade or public (including web-based promotional
				materials) or training materials is presumptively a fireplace model
				line. The presumption in this paragraph of this
				definition can be rebutted by test data from a United States environmental
				protection agency-approved test laboratory reviewed by a United States
				environmental protection agency-approved third-party certifier that were
				generated when operating the appliance with the doors closed, and that
				demonstrate an average stack gas carbon dioxide concentration over the duration
				of the test run equal to or less than 5.00 per cent and a ratio of the average
				stack gas carbon dioxide to the average stack gas carbon monoxide equal to or
				greater than 15:1. The stack gas average carbon dioxide and carbon monoxide
				concentrations for the test run shall be determined in accordance with the
				requirements in CSA B415.1-10 (R2020), clause 6.3, using a sampling interval no
				greater than one minute. The average stack gas carbon dioxide and carbon
				monoxide concentrations for purposes of this determination shall be the average
				of the stack gas concentrations from all sampling intervals over the full test
				run. (3) "Fuel" means wood, refuse,
			 natural gas, coke oven gas, petroleum, coal, and any combustible solid, liquid,
			 or gas derived from such materials. (4) "Fuel burning equipment"
			 means any furnace or boiler, and any appurtenances thereto such as stacks,

		  manufacturers; breweries; livestock feedlots; wheat flour, wet corn, dry corn,
		  rice mills; or soybean oil extraction plants. (H) [Reserved.] (I) "Incinerator" means any equipment, machine,
		  device, article, contrivance, structure, or part of a structure used to burn
		  liquid, semi-solid or solid refuse or to process salvageable materials by
		  burning other than by open burning as defined in rule 3745-19-01 of the
		  Administrative Code. (J) [Reserved.] (K) [Reserved.] (L) [Reserved.] (M) [Reserved.] (N) [Reserved.] (O)   (1) "OEPA" or "Ohio
			 EPA" means the Ohio environmental protection agency. (2) "Opacity" means the degree
			 to which emissions reduce the transmission of light and obscure the view of the

				Effective: August 25, 2023 [Comment: For dates and availability of
		non-regulatory government publications, publications of recognized
		organizations and associations, federal rules, and federal statutory provisions
		referenced in this rule, see paragraph (AA) of rule 3745-17-01 of the
		Administrative Code titled "referenced materials."] (A) For purposes of ascertaining,
		  defining, and measuring ambient air quality, PM2.5 and PM10 shall be measured by the methods specified in
		  paragraphs (P)(6) and (P)(7) of rule 3745-17-01 of the Administrative Code.
		  Such measurements for PM10 shall be
		  corrected to standard conditions for purposes of comparing measurements with
		  the ambient air quality standards set forth in rule 3745-25-02 of the
		  Administrative Code. (B) Emissions test methods and procedures
		  for all new and existing sources. (1) For the purpose of
			 determining compliance with paragraph (A)(1) of rule 3745-17-07 of the
			 Administrative Code, visible particulate emissions shall be determined
			 according to the following: (a) Except as provided in paragraph (B)(1)(b) of this rule, USEPA
				method 9 or continuous opacity monitoring as specified in paragraph (C) of this
				rule shall be employed. (b) As an alternative to the compliance procedures specified in
				paragraph (B)(1)(a) of this rule, coal-fired boilers with heat input capacities
				equal to or greater than two hundred fifty million Btu per hour that are
				controlled with either baghouses or electrostatic precipitators may determine
				compliance with the visible particulate emission limitations specified in
				paragraph (A)(1) of rule 3745-17-07 of the Administrative Code through the use
				of continuous opacity monitoring data. The continuous opacity monitoring system
				shall comply with the requirements specified in 40 CFR 60.13 and be certified
				in accordance with "USEPA Performance Specification 1." (The
				continuous opacity monitoring system consists of all the equipment used to
				acquire data and includes the data recording/processing hardware and software.)
				During each calendar quarter, the permittee shall be deemed in compliance with
				paragraph (A)(1) of rule 3745-17-07 of the Administrative Code if the following
				conditions are met: (i) The nonexempt opacity
				  values in excess of twenty per cent opacity are less than 1.10 per cent of the
				  six-minute average opacity values. (Exempt opacity values are defined in
				  paragraphs (A)(1)(b), (A)(2), and (A)(3) of rule 3745-17-07 of the
				  Administrative Code.) (ii) None of the
				  nonexempt six-minute average opacity values exceeds sixty per
				  cent. (iii) The total amount of
				  time, in hours, of exempt and nonexempt opacity values greater than twenty per
				  cent and less than sixty per cent (not including start-up, shutdown, and
				  malfunction exemptions provided in paragraphs (A)(2) and (A)(3) of rule
				  3745-17-07 of the Administrative Code) does not exceed the product of 0.10
				  times the actual number of hours the emissions unit was in operation during the
				  calendar quarter. In the event of a discrepancy between the
				continuous opacity monitoring data and any observations performed in accordance
				with paragraph (B)(1)(a) of this rule during the same time period, an
				evaluation may be performed by the Ohio EPA to assess the accuracy of the
				continuous opacity monitoring data (which may include an audit of the
				continuous opacity monitoring system performed in accordance with EPA
				340/1-86-010 (recommended quality assurance procedures for opacity continuous
				emission monitoring systems) and "Acid Rain Program Continuous Emission
				Monitoring Systems (CEMS) Field Audit Manual" and the validity of the
				observations performed in accordance with paragraph (B)(1)(a) of this rule. The
				Ohio EPA may accept and utilize any data or observation it finds credible. The
				permittee is not precluded from using any credible evidence in defense of any
				enforcement action that may be initiated by the Ohio EPA. (2) For the purpose of
			 determining compliance with paragraph (B)(2) of rule 3745-17-07 of the
			 Administrative Code, pertaining to visible particulate emissions from coke oven
			 batteries: (a) Charging operations: (i) The charging period
				  shall begin when the coal from the charging system starts to enter the oven and
				  end when the last charge port lid is replaced. Such charging period shall not
				  include the period of time during which the port lids are reopened in order to
				  sweep spilled coal into the oven. (ii) The observer shall
				  stand on the topside of the coke oven battery such that a good view of all
				  charge ports of the oven being charged and the charging system is possible. The
				  observer may change position to obtain a clear view of all oven ports, drop
				  sleeves, and hoppers. During the charging period, the observer shall watch all
				  the potential emission sources including the charge ports and the entire
				  charging system. Upon observing the release of any visible particulate
				  emission, an accumulative stopwatch shall be started. The watch shall be
				  stopped when the visible particulate emission stops and be restarted when a
				  visible particulate emission reappears. The observer shall continue this
				  procedure for the entire charging period. If visible particulate emissions
				  should occur simultaneously from several points during a charge, the visible
				  particulate emissions shall be timed collectively as one continuous visible
				  particulate emission. Furthermore, visible particulate emissions which may
				  start from one source immediately after those from another source shall be
				  timed as one continuous visible particulate emission. The following visible
				  particulate emissions shall not be timed: steam vapor, visible particulate
				  emissions from burning coal that is spilled on top of the oven or oven lid
				  during charging, visible particulate emissions emitted from any equipment other
				  than the charging system or charging ports, visible particulate emissions from
				  closed standpipes during charging, visible particulate emissions emitted from
				  coke oven doors which may rise above the battery and which may be windblown
				  across its topside, and visible particulate emissions that drift from the top
				  of the charging system, but have already been timed as a visible particulate
				  emission from the drop sleeve below the hopper. The time recorded on the
				  stopwatch shall represent the total time that visible particulate emissions are
				  observed during a charge. The number of seconds of visible particulate
				  emissions observed for each charge shall be recorded on a data
				  sheet. (iii) A minimum of six
				  consecutive charges shall be observed and the time in seconds of visible
				  particulate emissions during such charges shall be totalled. If the
				  observations of a set of consecutive charges is interrupted by an event not in
				  the control of an observer, then the data for the interrupted charges shall be
				  discarded and additional charges shall be observed until the total number of
				  consecutive charges equals at least six. For purposes of this paragraph,
				  charges immediately preceding and following any interrupted or discarded
				  charges shall be deemed consecutive. (b) Offtake piping and charging hole lids: (i) The observer shall
				  walk down the length of the top of the battery and complete the inspection in
				  an expeditious manner consistent with the safety of the observer. When safety
				  conditions permit, the observer will walk near the center of the battery, but
				  may deviate from this path to obtain a better view of any lid or offtake piping
				  system. Separate traverses may be performed for offtake piping and charging
				  hole lids. If the battery has two collector mains, the observer may make two
				  traverses when observing visible particulate emissions from offtake piping. If
				  an observer elects to make two traverses for a battery which has two collector
				  mains, the observer shall inspect one collector main during the first traverse
				  and inspect the other collector main during the second traverse. During each
				  traverse, the observer shall record the time of the beginning and end of each
				  traverse and the identity of any charging hole or offtake piping system having
				  visible particulate emissions. (ii) Visible particulate
				  emissions from offtake piping shall include emissions from cracks or defects in
				  the piping, emissions from the jointure of the battery to the standpipe,
				  emissions from the standpipe to the gooseneck and gooseneck to the collector
				  main, emissions from the seal between the gooseneck and gooseneck lid, and
				  emissions from opened offtake lids. Visible particulate emissions from charging
				  holes shall include emissions from the seal between the charging hole or
				  stationary jumper pipe lid and its casting, emissions from the charging hole or
				  stationary jumper pipe casting/battery interface, and emissions from opened
				  charging holes or stationary jumper pipe lids. Visible particulate emissions
				  which shall not be included are emissions caused by maintenance work in
				  progress at an oven, emissions caused by the vaporization of wet luting
				  materials, emissions caused by burning or smoldering excess topside coal, and
				  emissions from charging ports and offtake piping during the charging operation.
				  Visible particulate emissions from open offtake piping and charging holes, from
				  a maximum of three ovens, shall be exempt. Regardless of the number of points
				  from which visible particulate emissions are observed from any one offtake
				  piping system, the maximum entry for any oven with a single offtake system
				  shall be one and the maximum entry for any oven with two offtake piping systems
				  shall be two. The maximum number of charging hole leaks recorded for any oven
				  shall not exceed the number of charging holes on that oven. (iii) The percentage of
				  charging holes and offtake piping with visible particulate emissions shall be
				  determined by totalling the number of charging holes or offtake piping with
				  visible particulate emissions, including that number of opened charging holes
				  and offtake piping with visible particulate emissions which exceeds the amount
				  which is allowed for three ovens, dividing that number by the total number of
				  observed charging holes or offtake piping on operating ovens, and multiplying
				  the result by one hundred per cent. For purposes of this paragraph, any oven
				  which is not out of service for rebuild or maintenance work that is extensive
				  enough to require the oven to be skipped in the charging sequence shall
				  constitute an operating oven. Further, any opened charging hole or offtake
				  piping lids on operating ovens shall be included as observed charging holes and
				  offtake piping. (c) Oven doors: (i) The observer shall
				  observe visible particulate emissions by completely walking around the coke
				  oven battery at a steady distance from a position just outside the pusher
				  machine and quencher car tracks as close to the battery as safety and
				  visibility conditions permit. The observer shall traverse each side of a
				  battery expeditiously, recording the time of the beginning and end of each side
				  traverse, the identity of each door having visible particulate emissions, and
				  the identity of any door not observable during the traverse. A visible
				  particulate emission from an individual door shall be noted on an inspection
				  sheet when an observer determines any visible particulate emissions are
				  occurring from any location on the perimeter of a coke oven door or chuck door.
				  Visible particulate emissions observed at the top of the battery above a
				  specific oven door but not clearly attributable to such door shall not be
				  counted in this procedure. An observer shall observe each oven door only once
				  while scanning the perimeter for any visible particulate emissions. After a
				  brief scan of an oven door, the observer shall move along the observer's
				  traverse, checking subsequent doors on the battery in a like manner. If a
				  temporary machine obstruction occurs which blocks the view of a series of
				  ovens, the ovens shall be bypassed and the remaining oven doors on that side of
				  the battery shall be observed. After the traverse of such side of the battery,
				  the bypassed oven doors and only those oven doors, may be reobserved. After
				  completing one side, the observer shall proceed directly to the opposite side
				  of the battery and proceed to perform a like traverse while repeating the above
				  procedures. A row of two or more continuous batteries may be inspected by
				  observing all of the pusher side doors and then all of the coke side
				  doors. (ii) The percentage of
				  oven doors with visible particulate emissions shall be determined by totalling
				  the number of doors with visible particulate emissions, dividing that sum by
				  the total number of observed doors on operating ovens, and multiplying the
				  result by one hundred per cent. For purposes of this paragraph, any oven which
				  is not out of service for a rebuild or maintenance work that is extensive
				  enough to require that oven to be skipped in the charging sequence shall
				  constitute an operating oven. Further, any doors that are removed from
				  operating ovens shall constitute unobserved doors. (d) For any pushing operations, visible particulate emissions
				shall be determined according to USEPA method 9 with the following
				modifications: (i) Paragraph 2.5
				  ("Data Reduction") of USEPA method 9 shall not be used;
				  and (ii) Visible particulate
				  emission readings shall be recorded at fifteen-second intervals during each
				  pushing operation observed and the average reading during each such operation
				  shall be determined by summing the opacity readings and dividing this sum by
				  the number of observations during that pushing operation. (3) For the purpose of
			 determining compliance with paragraphs (B)(1), (B)(3), (B)(7)(a)(i), (B)(7)(b),
			 (B)(7)(c), and (B)(8)(a) to (B)(8)(d) of rule 3745-17-07 of the Administrative
			 Code, or with paragraphs (C)(3)(c), (D)(3), (F)(4)(c), (P)(2), (V)(4)(c),
			 (W)(2), (X)(2), and (X)(3) of rule 3745-17-12 of the Administrative Code,
			 visible emissions of fugitive dust shall be determined according to USEPA
			 method 9 with the following modifications: (a) For paragraphs (B)(1), (B)(7)(b), (B)(7)(c), (B)(8)(b), and
				(B)(8)(d) of rule 3745-17-07 of the Administrative Code, the data reduction and
				average opacity calculation shall be based upon sets of twelve consecutive
				visible emission observations recorded at fifteen-second
				intervals. (b) Opacity observations shall be made from a position that
				provides the observer a clear view of the source and the fugitive dust with the
				sun behind the observer. A position at least fifteen feet from the source is
				recommended. To the extent possible, the line of sight should be approximately
				perpendicular to the flow of fugitive dust and to the longer axis of the
				emissions. Except as provided in paragraphs (B)(3)(d) and (B)(3)(e) of this
				rule, opacity observations shall be made for the point of highest opacity
				within the fugitive dust. Since the highest opacity usually occurs immediately
				above or downwind of the source, the observer should normally concentrate on
				the area of the plume close to the source. For purposes of paragraphs (B)(7)(b)
				and (B)(8)(b) of rule 3745-17-07 of the Administrative Code, observations shall
				be made where the fugitive dust plume is distinctly separate from the falling
				material and from the surface of the pile. (c) [Reserved.] (d) For paragraphs (B)(7)(a)(i), (B)(8)(a), and (B)(8)(c) of rule
				3745-17-07 of the Administrative Code and paragraph (P)(2) of rule 3745-17-12
				of the Administrative Code: (i) A data set shall
				  consist of twelve observations based on four uninterrupted vehicle passes,
				  three observations per vehicle pass, using USEPA method 9. The initial
				  observation shall be taken immediately after passage of the first vehicle, at
				  the point of highest opacity within the fugitive dust, and at four feet above
				  the surface of the roadway or parking area. Two additional observations shall
				  be taken at the same point as the initial observation and at five seconds and
				  ten seconds after the initial reading. The same procedure shall be conducted
				  for the next three vehicle passes. If any interruption in observations during
				  any vehicle pass occurs, the observations taken during that vehicle pass shall
				  be discarded and the next vehicle pass shall be observed. For vehicle traffic
				  on top of any material storage pile, the observer may observe passes of the
				  same vehicle or vehicles, at identical of different points atop the pile, in
				  order to obtain readings for four vehicle passes. (ii) The data reduction
				  and average opacity calculation shall be based upon the average of twelve
				  observations in each data set. (e) For paragraph (B)(7)(c) of rule 3745-17-07 of the
				Administrative Code, observations of fugitive dust resulting from a
				vehicle's movement upon a coal storage pile shall be made at a point no
				less than one vehicle length from the rear of the vehicle and at an elevation
				no lower than the maximum height of the vehicle. For purposes of this rule,
				vehicle length and height shall be based upon the length and height of the
				vehicle being observed. (4) For the purpose of
			 determining compliance with paragraphs (B)(4) to (B)(6), (B)(7)(a)(ii), and
			 (B)(7)(d) of rule 3745-17-07 of the Administrative Code, paragraphs (C)(1),
			 (C)(2), (E), (F)(1) to (F)(3), (M)(1), (M)(2), (S)(4)(b), (U)(1), (U)(2),
			 (V)(1) to (V)(3), (W)(1), (W)(5), , and (Z) of rule 3745-17-12 of the
			 Administrative Code, or with paragraph (B) of rule 3745-17-13 of the
			 Administrative Code, visible emissions of fugitive dust shall be determined
			 according to USEPA method 22 with the following modifications: (a) If the observer's view is obscured and observations
				shall be terminated prior to completing the necessary or desired observation
				period, the observer shall clearly note this fact on the observation form. When
				the observer's view of the source is no longer obscured, the observations
				shall recommence to complete the observation period. (b) The observer shall identify on the observation form all
				interruptions due to rest breaks. (c) For the purpose of determining compliance with the applicable
				visible emission limitation, the observations, excluding break periods and
				periods of obscured vision, shall be considered continuous. (d) For any roadway or parking area, the observer shall determine
				the presence and duration of visible particulate matter at the same point of
				the potential emissions and at a height approximately four feet above the
				surface of the roadway or parking area. (5) Visible particulate
			 emission readings other than those referenced in paragraph (B)(4) of this rule
			 shall be determined by observers qualified according to tests and procedures
			 set forth in USEPA method 9. (6) The director may
			 refuse to accept the results of emission tests conducted pursuant to paragraphs
			 (B)(7) to (B)(10) of this rule which are not conducted with prior review and
			 approval of the test specifications by the director. Test specifications shall
			 be submitted for this purpose at least thirty days before the proposed test
			 date. The director will advise an entity of any deficiencies in the proposed
			 test specifications as expeditiously as practicable so as to minimize any
			 disruption of the proposed testing schedule. (7) For the purpose of
			 determining compliance with paragraphs (B)(3) and (B)(4) of rule 3745-17-08 of
			 the Administrative Code: (a) The amount of particulate emissions shall be determined by
				the test methods specified in paragraph (P)(1) of rule 3745-17-01 of the
				Administrative Code. (b) For electric arc furnaces at iron foundries, steel foundries
				and iron and steel mills, the sampling and measurement of the particulate
				emissions shall be performed only during those operating intervals commencing
				with the addition of cold scrap to the furnace and ending with the completion
				of the tapping of the furnace. (c) For argon-oxygen decarburization vessels, the sampling and
				measurement of the particulate emissions shall be performed only during those
				operating intervals commencing with the pouring of hot metal into the vessel
				and ending with the completion of the tapping of the vessel. (d) For basic oxygen furnaces, the sampling and measurement of
				the particulate emissions shall be performed only during those operating
				intervals commencing with the addition of hot metal to the furnace and ending
				with the completion of the tapping of the furnace. (e) For hot metal transfer operations, the sampling and
				measurement of the particulate emissions shall be performed only during those
				operating intervals when hot metal is being poured. (f) For hot metal desulfurization operations, the sampling and
				measurement of the particulate emissions shall be performed only during those
				operating intervals commencing with the initial injection of the
				desulfurization agent into the hot metal and ending with the completion of the
				injection process. (g) For blast furnace casthouses, the sampling and measurement of
				the particulate emissions shall be performed only during the casting operation,
				commencing with the opening of the tap hole and ending one minute after the
				positioning of the mud gun to plug the tap hole. (h) For pushing operations at coke oven batteries, one point of a
				probe traverse shall be sampled during each pushing operation and the sampling
				and measurement of the particulate emissions shall be performed only during
				those operating intervals commencing with the first movement of the ram and
				ending with the full extension of the ram plus ten seconds or with the first
				movement of the quench car, whichever occurs first. (8) For the purpose of
			 determining compliance with rule 3745-17-09 of the Administrative
			 Code: (a) The amount of particulate emissions from an incinerator shall
				be determined by test methods specified in paragraph (P)(1) of rule 3745-17-01
				of the Administrative Code. Emission tests shall be conducted at maximum
				burning capacity of the incinerator. (b) The maximum burning capacity of an incinerator shall be the
				manufacturer's or designer's guaranteed maximum rate or such other
				rate as may be determined by the director in accordance with good engineering
				practices. In case of conflict, the determination made by the director shall
				govern. (9) For the purpose of
			 determining compliance with rule 3745-17-10 of the Administrative Code and
			 paragraph (P)(1) of rule 3745-17-12 of the Administrative Code: (a) The amount of particulate emissions shall be determined by
				test methods specified in paragraph (P)(1) of rule 3745-17-01 of the
				Administrative Code, except that for USEPA method 5 the probe and filter holder
				heating systems in the sampling train shall be set to provide a gas temperature
				no greater than three hundred twenty degrees Fahrenheit (one hundred sixty
				degrees Celsius). (b) The heat content of fuels shall be determined according to
				ASTM D5685 or ASTM E870 for solid fuels, ASTM D240 for liquid fuels, and ASTM
				D1826 for gaseous fuels. (c) The ash content of coal shall be determined according to ASTM
				D3174. (10) For the purpose of
			 determining compliance with rule 3745-17-11 of the Administrative Code,
			 paragraphs (C)(3)(b), (D)(2), (F)(4)(b), (F)(5), (M)(3), (N)(4), (O)(3),
			 (O)(10), (P)(6), (P)(10), (S)(1) to (S)(4)(a), (U)(3), and (V)(4)(b) of rule
			 3745-17-12 of the Administrative Code, and paragraph (D)(3) of rule 3745-17-13
			 of the Administrative Code: (a) The amount of particulate emissions shall be determined by
				test methods specified in paragraph (P)(1) of rule 3745-17-01 of the
				Administrative Code. (b) The controlled mass rate of particulate emissions from
				sources equipped with control equipment, or the uncontrolled mass rate of
				particulate emissions from sources not equipped with control equipment, shall
				be determined by sampling and other measurements made at the air contaminant
				source or sources prior to the point at which air contaminants are emitted to
				the ambient air. For sources equipped with control equipment, the uncontrolled
				mass rate of emission may be determined by either sampling in the stack
				upstream from the inlet of the control equipment or by the use of other
				techniques accepted by the director. (c) For coke quench towers, the concentration of total dissolved
				solids in the quench water shall be determined according to Section 209(C),
				"Standard Methods for the Examination of Water and Wastewater," using
				a drying temperature between one hundred three and one hundred five degrees
				Celsius. Analyses shall be performed on grab samples of the quench water as
				applied to the coke. Samples shall be collected at a minimum of five days per
				week per quench tower and analyzed to report a weekly average concentration for
				each quench tower. Samples for each week shall be analyzed either: (i) Separately, with
				  daily concentrations determined and averaged as a weekly average,
				  or (ii) As one composite
				  sample, with equal volumes of each day's sample combined to form the
				  composite sample. (C) Continuous emission monitoring
		  requirements for measuring opacity for "Appendix P"
		  facilities. (1) Except as provided in
			 paragraphs (D) and (E) of this rule, for any air contaminant source subject to
			 40 CFR part 51, appendix P, "Minimum Emission Monitoring
			 Requirements," shall operate and maintain a continuous opacity monitoring
			 system (COMS) for measuring opacity. The COMS shall comply with all
			 specifications outlined in 40 CFR part 60, appendix B, "Performance
			 Specification 1." The COMS shall be capable of providing external
			 calibration filter access in accordance with Section 5.1.9 of "USEPA
			 Performance Specification 1." (2) Any owner or operator
			 of a facility that meets the applicability requirements specified in paragraph
			 (C)(1) of this rule shall submit reports to the director of excess emissions
			 for each calendar quarter within thirty days following the end of each calendar
			 quarter. The reports shall include, but not be limited to, the times and values
			 of all six-minute average readings of opacity above the applicable standard,
			 along with the dates, magnitudes (per cent opacity), reasons (if known), and
			 corrective actions taken (if any). In addition, the reports shall include the
			 dates and times of each period during which the continuous emission monitoring
			 system was inoperative, except for zero and span checks, and the nature of
			 system repairs or adjustments. (D) For any air contaminant source
		  subject to 40 CFR part 51, appendix P, "Minimum Emission Monitoring
		  Requirement" where the use of a COMS would not provide accurate
		  determinations of opacity as described in Section 6.1 of 40 CFR part 51,
		  appendix P, the owner or operator may elect to request, in writing, permission
		  from the director and the administrator to install, calibrate, certify,
		  maintain and operate a CEMS for measuring particulate emissions in lieu of
		  complying with paragraph (C)(1) of this rule. Upon approval of the use of the
		  CEMS by the director and the administrator, the air contaminant source shall
		  comply with the following: (1) The owner or operator
			 shall install, operate and maintain a CEMS for particulate emissions that meets
			 40 CFR part 60, appendix B, performance specification 11 and the
			 following: (a) The owner or operator shall conduct a performance evaluation
				of the CEMS according to 40 CFR 60.13, performance specification 11, and
				appendix F, procedure 2. (b) During each particulate emissions correlation testing run of
				the CEMS required by performance specification 11, particulate emissions and
				oxygen or carbon dioxide data shall be collected concurrently by both the CEMS
				and the performance tests conducted using the following: (i) For particulate
				  emissions, USEPA method 5 or 5B of 40 CFR part 60, appendix A shall be
				  used. (ii) For oxygen or carbon
				  dioxide, USEPA method 3A or 3B of 40 CFR part 60, appendix A, shall be
				  used. (c) Quarterly accuracy determinations and the daily calibration
				drift tests shall be performed in accordance with 40 CFR part 60, appendix F,
				procedure 2. Relative response audits shall be performed annually and response
				correlation audits using one-hour test runs shall be performed every three
				years. (2) Each air contaminant
			 source that is equipped with a CEMS for particulate emissions in lieu of using
			 COMS shall comply with a particulate emissions limit of 0.030 pounds of
			 particulate emissions per million British thermal units of heat input, based
			 upon a daily average, and any other mass emission limit that
			 applies. (3) Compliance with the
			 daily average particulate emission limitation shall be determined by
			 calculating the arithmetic average of all valid CEMS hourly emission rates for
			 particulate emissions for each air contaminant source operating
			 day. (E) For any air contaminant source
		  subject to 40 CFR part 51, appendix P, "Minimum Emission Monitoring
		  Requirement" where the use of a COMS would not provide accurate
		  determinations of opacity as described in 40 CFR part 51, appendix P, section
		  6.1, the owner of operator may elect to request, in writing, approval from the
		  director and the administrator of an alternative monitoring plan for
		  determining compliance with particulate emissions, in lieu of complying with
		  paragraph (C)(1) of this rule. Upon approval of the use of the alternative
		  monitoring plan by the director and the administrator, the air contaminant
		  source shall comply with the following: (1) The monitoring
			 requirements and ranges of the parameters to be monitored shall be incorporated
			 into the underlying federally enforceable permit-to-install and Title V permit
			 as federally enforceable limits. (2) The federally
			 enforceable ranges of the parameters to be monitored shall be established such
			 that, during the initial performance testing required under 40 CFR 60.8,
			 performance testing required by permit, or other performance testing as
			 required by law, USEPA method 5B testing shows the air contaminant source is
			 complying with any particulate matter mass limit applicable to the air
			 contaminant source while operating within those ranges. (3) Each instance where
			 any parameter required to be monitored under the alternative monitoring plan
			 falls outside the federally enforceable ranges is considered a violation of the
			 applicable particulate emissions limit, and shall be reported in quarterly
			 excess emission reports required by the permit. The quarterly excess emission
			 reports shall satisfy 40 CFR 60.7 and the permits and shall include, at a
			 minimum, the following: (a) The date the parameter was outside of the range. (b) The time the parameter was outside of the range. (c) The value of the parameter during the period it was outside
				of the range. (d) The cause of the parameter to be outside of the
				range. (e) The corrective action taken to bring the parameter back into
				the federally enforceable range.

				Effective: August 25, 2023 [Comment: For dates and availability of
		non-regulatory government publications, publications of recognized
		organizations and associations, federal rules, and federal statutory provisions
		referenced in this rule, see paragraph (AA) of rule 3745-17-01 of the
		Administrative Code titled "referenced materials."] (A) Applicability: (1) Except as otherwise
			 specified in paragraph (A)(3) of this rule, paragraph (B) of this rule shall
			 apply to any fugitive dust source which is located within the areas identified
			 in appendix A to this rule. Except as additional time for achieving compliance
			 is provided in paragraph (B) of rule 3745-17-04 of the Administrative Code, any
			 such source shall comply with paragraph (B) of this rule by August 7, 1972 or
			 the date of initial startup of the source, whichever is later. (2) Notwithstanding the
			 exemptions in paragraph (A)(3) of this rule, paragraph (B) of this rule shall
			 apply to any fugitive dust source regardless of location if, in the
			 director's judgment, probable cause exists to believe that such source is
			 causing or contributing to a violation of rule 3745-15-07 of the Administrative
			 Code. In such cases, the director may require the owner or operator of the
			 fugitive dust source to apply for and obtain an operating permit in accordance
			 with Chapter 3745-77 of the Administrative Code (for sources subject to the
			 Title V permit program) or an a permit-to-install and operate in accordance
			 with Chapter 3745-31 of the Administrative Code (for sources not subject to the
			 Title V permit program), or require the owner or operator to submit and
			 implement a control program which will bring the fugitive dust source into
			 compliance with paragraph (B) of this rule as expeditiously as
			 practicable. [Comment: Applications requiring submittal
			 prior to June 30, 2008, for sources not subject to the Title V program, were to
			 be submitted in accordance with now rescinded Chapter 3745-35 of the
			 Administrative Code.] (3) Paragraph (B) of this
			 rule shall not apply to: (a) Any fugitive dust source which is located at a grain elevator
				having a permanent storage capacity of less than 2.5 million
				bushels. (b) [Reserved.]  (c) Fugitive dust generated from publicly owned roadways and
				parking lots, provided the fugitive dust is not directly caused by the
				deposition of materials due to industrial, commercial, or construction
				activities. (d) Fugitive dust generated from the tilling and wind erosion of
				farm land. (e) Fugitive dust generated from any roadway or parking area at
				the "JSW Steel USA Ohio" or any subsequent owner or operator of the
				"JSW Steel USA Ohio" facility located at 540 Commercial avenue, Mingo
				Junction, Ohio (OEPA premise number 0641090010). (f) Fugitive dust generated from residential wood burning
				appliances and pellet stoves. (4) An air contaminant
			 source can be subject to both rule 3745-17-11 of the Administrative Code and
			 this rule if it is a fugitive dust source, as defined in paragraph (F)(5) of
			 3745-17-01 of the Administrative Code, and also emits, by means of one or more
			 stacks, particulate matter that is subject to a limitation in rule 3745-17-11
			 of the Administrative Code. (B) No person shall cause or permit any
		  fugitive dust source to be operated; or any materials to be handled,
		  transported, or stored; or a building or its appurtenances or a road to be
		  used, constructed, altered, repaired, or demolished without taking or
		  installing reasonably available control measures to prevent fugitive dust from
		  becoming airborne. Such reasonably available control measures shall include,
		  but not be limited to, one or more of the following which are appropriate to
		  minimize or eliminate visible particulate emissions of fugitive
		  dust: (1) The use of water or
			 other suitable dust suppression chemicals for the control of fugitive dust from
			 the demolition of existing buildings or structures, construction operations,
			 the grading of roads or the clearing of land. (2) The periodic
			 application of asphalt, oil (excluding any used oil as defined in paragraph (A)
			 of rule 3745-279-01 of the Administrative Code), water, or other suitable dust
			 suppression chemicals on dirt or gravel roads and parking lots, and other
			 surfaces which can cause emissions of fugitive dust. (3) The installation and
			 use of hoods, fans, and other equipment to adequately enclose, contain,
			 capture, vent and control the fugitive dust. Such equipment shall meet the
			 following requirements: (a) The collection efficiency is sufficient to minimize or
				eliminate visible particulate emissions of fugitive dust at the point of

				Effective: August 25, 2023 (A) This rule applies to installations in
		  which fuel, including any product or by-product of a manufacturing process, is
		  burned for the primary purpose of producing heat or power by indirect heat
		  transfer. (B) For purposes of this rule the actual
		  heat input shall be the aggregate heat content of all fuels whose products of
		  combustion emanate from a single fuel burning unit. The maximum capacity shall
		  be the equipment manufacturer's or designer's guaranteed maximum heat
		  input, whichever is greater. Unless otherwise specified in paragraphs (B)(1) to
		  (B)(4) of this rule, the total heat input of all fuel burning units on a plant
		  or premises which are united either physically or operationally shall be the
		  total of the maximum capacities for all such units. The total heat input shall
		  be used for determining the maximum allowable amount of particulate emissions
		  per million Btu of actual heat input from any single fuel burning
		  unit. (1) Any new or existing
			 fuel burning equipment which is fired only with gaseous fuels or number two
			 fuel oil and which is physically or operationally united with other fuel
			 burning equipment on a plant or premises shall not be included by the director
			 for purposes of determining the total heat input and maximum allowable
			 particulate emissions per million Btu of actual heat input for such other fuel
			 burning equipment. The maximum allowable amount of particulate emissions for
			 any new or existing fuel burning equipment which is fired only with gaseous
			 fuels, excluding blast furnace gas or number two fuel oil shall be 0.020 pound
			 per million Btu of actual heat input. The maximum allowable amount of
			 particulate emissions for any new or existing fuel burning equipment which is
			 fired only with blast furnace gas or any mixture of blast furnace gas with
			 other gaseous fuels or number two fuel oil shall be 0.040 pound per million Btu
			 of actual heat input. (2) Stand-by fuel burning
			 equipment which is physically or operationally united with other fuel burning
			 equipment on a plant or premises shall be exempted by the director for purposes
			 of determining total heat input and maximum allowable particulate emissions per
			 million Btu of actual heat input for such other fuel burning equipment. Except
			 as provided in paragraph (B)(1) of this rule, the total heat input for such
			 other fuel burning equipment shall be used for determining the maximum
			 allowable amount of particulate emissions per million Btu of actual heat input
			 for any stand-by fuel burning equipment. (3) Derating of fuel
			 burning equipment. (a) For purposes of this paragraph, fuel burning equipment shall
				include, where appropriate, all equipment on a plant or premises which are
				united either physically or operationally. (b) Upon request, the director may specify the total heat input
				for fuel burning equipment at a derated value which is less than the total
				maximum capacity of such equipment if, in the director's judgment, the
				equipment will not be operated so that the actual heat input exceeds the
				derated value. Any owner or operator requesting derating of fuel burning
				equipment shall demonstrate to the director, with such steam charts, records of
				fuel consumption and fuel quality, and other data as are necessary, that the
				actual heat input from the equipment will not exceed the derated total heat
				input value. (c) The terms and conditions of any permit, variance, or order
				for equipment which has been granted a derated total heat input value shall
				prohibit the operation of such equipment at a level in excess of the derated
				total heat input value. The director may include in any such permit, variance,
				or order requirements for the monitoring and reporting of the actual heat input
				of the equipment. (d) Any derating of fuel burning equipment approved by the
				director shall not revise the federally enforceable requirements of the state
				implementation plan until approved by the United States environmental
				protection agency. (4) Fuel burning
			 equipment which constitutes a new source and is physically or operationally
			 united with existing fuel burning equipment on a plant or premises shall not be
			 included by the director for purposes of determining total heat input and
			 maximum allowable particulate emissions per million Btu of actual heat input
			 for such existing fuel burning equipment. Except as may be provided in
			 paragraphs (B)(1) or (B)(2) of this rule, the total heat input for the new and
			 existing fuel burning equipment shall be used for determining the maximum
			 allowable amount of particulate emissions per million Btu of actual heat input
			 for the new fuel burning equipment. (C) Emission limitations. (1) Except as provided in
			 paragraph (B)(1) of this rule (as it pertains to gaseous fuels and number two
			 fuel oil) and paragraph (C)(7) of this rule, any owner or operator of fuel
			 burning equipment which is located within the following counties shall operate
			 said equipment so that the particulate emissions do not exceed the allowable
			 emission rate specified by "Curve P-1" of "Figure I" in the
			 appendix to this rule: Adams, Allen, Ashtabula, Athens, Belmont, Brown, Butler,
			 Clark, Clermont, Clinton, Columbiana, Coshocton, Cuyahoga, Darke, Defiance,
			 Delaware, Fairfield, Franklin, Gallia, Geauga, Greene, Hamilton, Henry,

			 Pickaway, Portage, Preble, Richland, Ross, Sandusky, Scioto, Seneca, Shelby,
			 Stark, Summit, Trumbull, Union, Warren, Washington, Wyandot and
			 Wood. (2) Except as provided in
			 paragraph (B)(1) of this rule (as it pertains to gaseous fuels and number two
			 fuel oil) and paragraph (C)(7) of this rule, any owner or operator of fuel
			 burning equipment which is located within the following counties shall operate
			 said equipment so that the particulate emissions do not exceed the allowable
			 emission rate specified by "Curve P-2" of "Figure I" in the
			 appendix to this rule: Ashland, Auglaize, Carroll, Champaign, Crawford, Erie,
			 Fayette, Fulton, Guernsey, Hancock, Hardin, Harrison, Highland, Hocking,
			 Holmes, Huron, Knox, Logan, Marion, Mercer, Morrow, Ottawa, Paulding, Pike,
			 Putnam, Tuscarawas, Van Wert, Vinton, Wayne and Williams. (3) 
			 [Reserved.] (4) [Reserved.] (5) [Reserved.] (6) [Reserved.] (7) Alternative emission
			 requirements for small coal-fired fuel burning equipment which is used
			 exclusively for space heating purposes. (a) Any owner or operator of coal-fired fuel burning equipment,
				which has an individual maximum capacity of equal to or greater than one
				million Btu per hour and less than twenty million Btu per hour and which is
				used exclusively for space heating purposes, may choose to immediately comply
				with all the following requirements in lieu of paragraph (C)(1) or (C)(2) of
				this rule: (i) The coal received for
				  use in the fuel burning equipment has an ash content of less than 8.0 per cent
				  by weight and a heat content of greater than thirteen thousand Btu per pound
				  (ash content and heat content shall be determined on a dry basis in accordance
				  with the procedures specified in paragraph (B)(9) of rule 3745-17-03 of the
				  Administrative Code). (ii) The use of flyash
				  reinjection in the coal-fired fuel burning equipment is
				  prohibited. (iii) The coal-fired fuel
				  burning equipment employs an overfire air system which is designed, maintained
				  and operated in accordance with good engineering practice and which minimizes
				  visible particulate emissions from the fuel burning equipment. (iv) Except as otherwise
				  provided in paragraph (A)(3) of rule 3745-17-07 of the Administrative Code, the
				  visible particulate emissions from the coal-fired fuel burning equipment comply
				  with paragraph (A)(1) of rule 3745-17-07 of the Administrative Code. No
				  coal-fired fuel burning equipment which is subject to the alternative emission
				  requirements of this rule shall be eligible for an equivalent visible
				  particulate emission limitation pursuant to paragraph (C) of rule 3745-17-07 of
				  the Administrative Code. (v) The coal-fired fuel
				  burning equipment is operated and maintained in a manner which will optimize
				  combustion efficiency and minimize visible particulate emissions. (vi) During January and
				  July of each year, the owner or operator shall submit reports to the director
				  which document the quality and quantity (on a dry basis) of each shipment of
				  coal received during the previous six calendar months for the coal-fired fuel
				  burning equipment and which demonstrate compliance with paragraph (C)(7)(a)(i)
				  of this rule. Data provided by the coal supplier may be used for these
				  semi-annual reports if such data are accurate and representative of the quality
				  and quantity of each shipment of coal received for the fuel burning
				  equipment. (b) Any owner or operator of coal-fired fuel burning equipment
				who chooses to comply with paragraph (C)(7)(a) of this rule in lieu of
				paragraph (C)(1) or (C)(2) of this rule shall notify the director in writing.
				The written notification shall include sufficient information and commitments
				to demonstrate compliance with paragraph (C)(7)(a) of this rule. If the
				information and commitments are adequate to demonstrate compliance with
				paragraph (C)(7)(a) of this rule on a continuing basis, the alternative
				emission requirements shall be specified in the terms and conditions of the

				Effective: August 25, 2023 (A) General provisions: (1) This rule applies to
			 any operation, process, or activity which releases or may release particulate
			 emissions into the ambient air except the following: (a) The burning of fuel for the primary purpose of producing heat
				or power by indirect heating in which the products of combustion do not come
				into direct contact with process materials. (b) The burning of refuse. (c) The processing of salvageable material by
				burning. (d) The loading of ships and the drying of grain at grain
				elevator operations. (e) Salt glazing in a gas-fired periodic brick or tile kiln, for
				a period of not more than two hours during any twenty-one consecutive days of
				operation of said kiln. (f) The generation of fugitive dust which the director has
				determined is subject to rule 3745-17-08 of the Administrative
				Code. (g) Any such operation, process, or activity which is subject to
				a particulate emission limitation contained in rule 3745-17-12 or 3745-17-13 of
				the Administrative Code. (h) Surface coating processes that apply only dip coatings, roll
				coatings, flow coatings, or brush coatings. (i) Surface coating processes that use less than five gallons of
				coatings per day that are not exempt under paragraphs (A)(1)(h), and (A)(1)(j)
				to (A)(1)(l) of this rule, provided the owner or operator maintains coating
				usage and application method records, coating purchase records, or production
				records that clearly demonstrate the actual coating usage is less than five
				gallons per day. (j) Surface coating processes (e.g., for sealers, adhesives, and
				deadeners) that employ airless spray and bead-type (extrusion) application
				methods. (k) Surface coating processes that employ hand-held cup spray
				guns. (l) Surface coating processes for which the owner or operator
				demonstrates to the satisfaction of the director that, due to the large size of
				the item being coated, it is technically infeasible or economically
				unreasonable (in terms of cost-effectiveness) to employ an enclosure (or
				hooding) and control device for the control of the particulate emissions (any
				such exemption approved by the director shall be approved by the United States
				environmental protection agency as a revision of the state implementation
				plan). (m) Jet engine test cells and stands. (n) Residential wood burning appliances and pellet
				stoves. (2) Emission restriction
			 requirements for sources, which are not subject to paragraph (B)(4), (B)(5),
			 (B)(6) or (C) of this rule or which are not exempted under paragraph (A)(1) of
			 this rule, are specified in "Figure II" and in "Table I" in
			 the appendix to this rule. "Figure II" in the appendix to this rule
			 relates uncontrolled mass rate of emission (abscissa) to maximum allowable mass
			 rate of emission (ordinate). A source complies with "Figure II" in
			 the appendix to this rule if its particulate emission rate, even during
			 operation at the maximum capacity of the source, is always equal to or less
			 than the allowable mass rate of emission of particulate matter (A) based upon
			 the uncontrolled mass rate of emission (U). "Table I" in the appendix
			 to this rule relates process weight of materials introduced into any specific
			 process (at its maximum capacity) that may result in particulate emissions to
			 maximum allowable mass rate of emission. Solid fuels charged will be considered
			 as part of the process weight, but liquid and gaseous fuels when they are used
			 solely as fuels and combustion air will not. A source complies with "Table
			 I" in the appendix to this rule if its rate of particulate emission, even
			 during operation at the process weight rate (P) which reflects the maximum
			 capacity of the source, is always equal to or less than the allowable rate of
			 particulate emission specified by the appropriate equation appearing at the
			 bottom of "Table I" in the appendix to this rule and incorporating
			 the process weight rate (P) which reflects the maximum capacity of the source.
			 Except as otherwise indicated in paragraphs (A)(2)(a) to (A)(2)(c) of this
			 rule, the more stringent of the two requirements shall apply. (a) "Figure II" in the appendix to this rule shall not
				apply to any of the following: (i) Any source where the
				  uncontrolled mass rate of emission cannot be ascertained. (ii) Any source with an
				  uncontrolled mass rate of emission of less than ten pounds per
				  hour. (iii) Any fluid catalytic
				  cracking unit at a petroleum refinery. (b) "Table I" in the appendix to this rule shall not
				apply to any of the following: (i) Any source where the
				  process weight rate cannot be ascertained. (ii) Any source which is
				  located within the counties specified in paragraphs (B)(2) and (B)(3) of this
				  rule, except as provided in paragraph (A)(2)(c) of this rule. (c) "Table I" in the appendix to this rule shall apply
				to any fluid catalytic cracking unit at a petroleum refinery. (3) For purposes of
			 "Figure II" in the appendix to this rule, the total uncontrolled mass
			 rate of emission from all similar process units at a plant, such units being
			 united either physically or operationally, or otherwise located in close
			 proximity to each other, shall be used for determining the maximum allowable
			 mass rate of particulate emissions that pass through a stack or stacks from all
			 such units. (4) For purposes of
			 "Table I" in the appendix to this rule, process weight per hour is
			 the total weight of all materials introduced into any single, specific process
			 (at its maximum capacity) that may cause any emission of particulate matter.
			 Solid fuels charged will be considered as part of the process weight, but
			 liquid and gaseous fuels when they are used solely as fuels and combustion air
			 will not. For a cyclical or batch operation, the process weight per hour will
			 be derived by dividing the total process weight by the number of hours in one
			 complete operation from the beginning of any given process to the completion
			 thereof, excluding any time during which the equipment is idle. For a
			 continuous operation, the process weight per hour will be derived by dividing
			 the process weight for a given period of time by the number of hours in that
			 period. For fluid catalytic cracking units at petroleum refineries,
			 "process weight" shall mean the total weight of recirculated catalyst
			 and cold catalyst introduced into the catalyst regenerator. (5) An air contaminant
			 source can be subject to both rule 3745-17-08 of the Administrative Code and
			 this rule if it is a fugitive dust source, as defined in paragraph (F)(5) of
			 3745-17-01 of the Administrative Code, and also emits, by means of one or more
			 stacks, particulate matter that is subject to a limitation in rule 3745-17-08
			 of the Administrative Code. (B) Emission limitations: (1) Except as specified
			 in paragraph (B)(4), (B)(5), (B) (6) or (C) of this rule, any owner or operator
			 of a source of particulate emissions which is located within the following
			 counties shall operate said source so that the particulate emissions do not
			 exceed the allowable emission rate specified by "curve P-1" of
			 "Figure II" or by "Table I" in the appendix to this rule,
			 whichever is applicable under paragraph (A)(2) of this rule: Adams, Allen,
			 Ashtabula, Athens, Belmont, Brown, Butler, Clark, Clermont, Clinton,
			 Columbiana, Coshocton, Cuyahoga, Darke, Defiance, Delaware, Fairfield,
			 Franklin, Gallia, Geauga, Greene, Hamilton, Henry, Jackson, Jefferson, Lake,
			 Lawrence, Licking, Lorain, Lucas, Madison, Mahoning, Medina, Meigs, Miami,
			 Monroe, Montgomery, Morgan, Muskingum, Noble, Perry, Pickaway, Portage, Preble,
			 Richland, Ross, Sandusky, Scioto, Seneca, Shelby, Stark, Summit, Trumbull,
			 Union, Warren, Washington, Wyandot and Wood. (2) Except as otherwise
			 provided in paragraph (B)(4), (B)(5) or (C) of this rule, any owner or operator
			 of a source of emissions which is located within the following counties shall
			 operate said source so that the particulate emissions do not exceed the
			 allowable emission rate specified by "curve P-2" of "Figure
			 II" in the appendix to this rule: Ashland, Auglaize, Carroll, Champaign,
			 Crawford, Fulton, Guernsey, Hancock, Hardin, Harrison, Holmes, Knox, Logan,
			 Marion, Mercer, Morrow, Paulding, Putnam, Tuscarawas, Van Wert, Wayne and
			 Williams. (3) Except as otherwise
			 provided in paragraph (B)(4), (B)(5) or (C) of this rule, any owner or operator
			 of a source of particulate emissions which is located within the following
			 counties shall operate said source so that the particulate emissions do not
			 exceed the allowable emission rate specified by "curve P-3" of
			 "Figure II" in the appendix to this rule: Erie, Fayette, Highland,
			 Hocking, Huron, Ottawa, Pike and Vinton. (4) Any owner or operator
			 of a stationary gas turbine shall not cause or permit the particulate emissions
			 from the turbine's exhaust to exceed 0.040 pound per million Btu of actual
			 heat input. (5) Any owner or operator
			 of a stationary internal combustion engine shall not cause or permit the
			 particulate emissions from the engine's exhaust to exceed the
			 following: (a) 0.310 pound per million Btu of actual heat input for a
				stationary small internal combustion engine. (b) 0.062 pound per million Btu of actual heat input for a
				stationary large internal combustion engine. (6) The
			 "Cleveland-Cliffs Cleveland Works LLC " (OEPA premise number
			 1318001613) or any subsequent owner or operator of the"Cleveland-Cliffs
			 Cleveland Works LLC" facility located at 3060 Eggers avenue, Cleveland,
			 Ohio shall not cause or permit the particulate emissions from the 84-inch hot
			 strip mill reheat furnaces (OEPA source numbers P046 to P048) to exceed 19.8
			 pounds per hour per furnace. (C) Requirements for surface coating
		  processes: (1) Any surface coating
			 process not exempt under paragraphs (A)(1)(h) to (A)(1)(l) of this rule shall
			 be controlled by a dry particulate filter, waterwash, or equivalent control
			 device or devices. (2) Any surface coating
			 process not exempt under paragraphs (A)(1)(h) to (A)(1)(l) of this rule shall
			 follow all of the following work practices: (a) The owner or operator shall maintain documentation of the
				manufacturer's recommendations, instructions, or operating manuals for the
				control devices with any modifications deemed necessary by the owner or
				operator during the time period in which the control devices are
				utilized. (b) The owner or operator shall operate the control devices in
				accordance with the manufacturer's recommendations, instructions, or
				operating manuals with any modifications deemed necessary by the owner or
				operator. (c) The owner or operator shall conduct periodic inspections of
				the control devices to determine whether the devices are operating in
				accordance with the manufacturer's recommendations, instructions, or
				operating manuals with any modifications deemed necessary by the owner or
				operator. The periodic inspections of each control device shall be performed at
				a frequency that is based upon the recommendation of the manufacturer of the
				control device, and the owner or operator shall maintain a copy of the
				manufacturer's recommended inspection frequency. In addition to these
				periodic inspections, not less than once each calendar year the owner or
				operator shall conduct a comprehensive inspection of the control device while
				the emissions unit is shut down and perform any needed maintenance and repair
				for the control device to ensure that it is able to routinely operate in
				accordance with the manufacturer's recommendations. (d) The owner or operator shall document each inspection of a
				control device by maintaining a record that includes the date of the
				inspection, a description of each problem identified and the date it was
				corrected, a description of the maintenance and repairs performed, and the name
				of the person who performed the inspection. (e) In the event that the control devices are not operating in
				accordance with the manufacturer's recommendations, instructions, or

				Effective: August 25, 2023 (A) By not later than April 1, 1992, the owner or operator of each facility identified below shall submit to the Ohio EPA approvable control strategies and compliance schedules which meet the following: (1) Contain control strategies  capable of reducing the particulate emissions from each of the facilities identified in this paragraph by each of the two levels specified in this paragraph for each facility: | Facility Name (premise number) | Total, required particulate emission reductions for the facility (in pounds per hour at the maximum operating rates) |  |  | Fifteen per cent reduction level | Twenty-five per cent reduction level |  | International Mill Service, Incorporated (1741090068) | 0.8 | 0.8 | 
 (2) Except as otherwise provided in this paragraph, the particulate emission reductions specified in paragraph (A)(1) of this rule shall be obtained from the sources identified for each affected facility in rules 3745-17-12 and 3745-17-13 of the Administrative Code. If the required reductions cannot reasonably be obtained from those sources, control strategies may be developed for other sources at the facility in order to meet the required reductions for the facility. (3) In calculating the control strategy, hourly particulate emission rate for a source, the maximum operating rate for the source shall be used. In addition, for a source identified in rule 3745-17-12 or 3745-17-13 of the Administrative Code, the baseline, hourly particulate emission rate shall be based upon the allowable emission rate specified in those rules and the maximum operating rate; and the control strategy shall be designed to reduce the particulate emissions below that baseline, hourly particulate emission rate. For a source which is not identified in rule 3745-17-12 or 3745-17-13 of the Administrative Code, the baseline, hourly particulate emission rate shall be based upon the actual or allowable emission rate, whichever is lower, and the maximum operating rate; and the control strategy shall be designed to reduce the particulate emissions below that baseline, hourly particulate emission rate. (4) The following information shall be submitted for each source for which a control strategy is developed: (a) A description of the source and the existing control equipment or control measures. (b) The Ohio EPA application number. (c) The hourly, baseline particulate emission rate, and the assumptions and calculations which were used to derive the emission rate. (d) A description of the type of control equipment or control measures which will be employed to reduce the hourly emission rate, including the general design specifications or operating parameters. (e) The hourly particulate emission rate that will be achieved by employing the proposed control equipment or control measures, and the assumptions and calculations which were used to derive the emission rate. (f) The approximate total installed cost and annual operating cost for the proposed control equipment or control measures, and the assumptions and calculations which were used to derive the costs. (5) The schedule for implementing each control strategy shall commence upon a formal determination and notification by the Ohio EPA or the United States environmental protection agency that the county where the facility is located is not in compliance with the ambient air quality standards for PM10, as specified in rule 3745-25-02 of the Administrative Code. The schedule shall include dates for the following milestones: (a) Award contracts for emission control systems or process modifications, or issue orders for the purchase of component parts to accomplish emission control or process modification. (b) Initiate on-site construction or installation of emission control equipment or process change. (c) Complete on-site construction or installation of emission control equipment or process change. (d) Achieve final compliance. The owner or operator shall demonstrate to the satisfaction of the director that the schedule is as expeditious as practicable. (B) The control strategies and compliance schedules submitted in accordance with paragraph (A) of this rule shall be approved by the director through the issuance, pursuant to division (R) of section 3704.03 of the Revised Code, of administrative findings and orders. The findings and orders shall be submitted to and approved by the United States environmental protection agency as a revision to the Ohio state implementation plan for particulates. (C) Upon a formal determination and notification by the Ohio EPA or the United States environmental protection agency that Cuyahoga county or Jefferson county is not in compliance with the ambient air quality standards for PM10, as specified in rule 3745-25-02 of the Administrative Code, the owner or operator of each facility identified in paragraph (A)(1) of this rule shall implement the control strategies and schedules which have been approved by the director. (Such formal determination and notification of nonattainment shall not occur prior to January 1, 1994.) If the determination and notification of nonattainment are based upon a twenty-four-hour average ambient air concentration of PM10 of greater than one hundred fifty micrograms per cubic meter and less than or equal to one hundred seventy-two and one half micrograms per cubic meter, the owner or operator of each affected facility shall implement the set of approved control strategies and compliance schedules which are designed to reduce the hourly particulate emission rate by fifteen per cent or more. If the determination and notification of nonattainment are based upon a twenty-four-hour average ambient air concentration of PM10 of greater than one hundred seventy-two and one half micrograms per cubic meter, the owner or operator of each affected facility shall implement the approved control strategies and compliance schedules which are designed to reduce the hourly particulate emission rate by twenty-five per cent or more. (D) Notwithstanding paragraph (C) of this rule, if the determination and notification of nonattainment referenced in paragraph (C) of this rule reflects continued nonattainment in only a portion of the county, the director may limit the requirement for implementation of contingency measures to those facilities which are identified in paragraph (A)(1) of this rule and which are located either in that portion of Jefferson county within a two-kilometer radius from the ambient air quality monitor showing continued nonattainment or in that portion of Cuyahoga county within a three-kilometer radius from the ambient air quality monitor showing continued nonattainment. (E) For purposes of this rule, PM10 is defined and determined in accordance with paragraph (P)(7) of rule 3745-17-01 of the Administrative Code.
