[Comment: For dates of non-regulatory government publications, publications of 

recognized organizations and associations, federal rules, and federal statutory provisions 

referenced in this rule, see paragraph (HHJJ) of rule 3745-21-01 of the Administrative 

Code titled "R:efeFeReeElReference to materials."] 

(A) Applicability. 

The requirements of this rule shall apply to any storage tank that meets all of the 

following criteria: 

(l) Tanks that store volatile organic liquids; 

(2) The tank is located in Ashtabula, Cuyahoga, Geauga, Lake, Lorain, Medina, 

Portage, or Summit county; and 

(3) The facility has a combined total potential to emit for VOC emissions equal to 

or greater than one hundred tons of VOCs per calendar year on or after May 

27,2005, from all of the following: 

(a) All volatile organic liquid storage tanks; 

(b) All non-CTG sources; and 

(c) Unregulated emissions from CTG sources. 

(B) The definitions applicable to this rule are contained in paragraphs (B) and (E) of rule 

3745-21-01 of the Administrative Code. 

(C) Storage of volatile organic liquids in fixed roof tanks. 

(!) Except where exempted under paragraph (C)(5) of this rule, no owner or 

operator of a fixed roof tank shall place, store, or hold any volatile organic 

liquid with a maximum true vapor pressure which is greater than 0.75 pounds 

per square inch absolute, but less than 11.1 pounds per square inch absolute, 

in any such tank, after the date specified in paragraph (G) of this rule, unless 

such tank is designed or equipped with one of the following vapor control 

systems: 

(a) An internal floating roof meeting the requirements of paragraph (C)(3) of 

this rule; or: 
3745-21-21 2 

(b) A closed vent system and control device meeting the requirements of 

paragraph (C)(4) of this rule. 

(2) Except where exempted under paragraph (C)(5) of this rule, no owner or 

operator of a fixed roof tank shall place, store, or hold any volatile organic 

liquid with a maximum true vapor pressure which is equal to or greater than 

11.1 pounds per square inch absolute, in any such tank, after the date 

specified in paragraph (G) of this rule, unless such tank is designed or 

equipped with a closed vent system and control device meeting the 

requirements of paragraph (C)(4) of this rule. 

(3) If the fixed roof tank is equipped with an internal floating roof, the following 

requirements and specifications shall be met: 

(a) The intemal floating roof shall rest or float on the liquid surface (but not 

necessarily in complete contact with it) inside a storage vessel that has a 

fixed roof. The internal floating roof shall float on the liquid surface at 

all times, except during initial fill and during those intervals when the 

storage vessel is completely emptied or subsequently emptied and 

refilled. When the roof is resting on the leg supports, the process of 

filling, emptying, or refilling shall be continuous and shall be 

accomplished as rapidly as possible. 

(b) Each intemal floating roof shall be equipped with one of the following 

closure devices between the wall of the storage vessel and the edge of 

the intemal floating roof: 

(i) A foam or liquid-filled seal mounted in contact with the liquid 

(liquid-mounted seal). A liquid-mounted seal means a foam or 

liquid-filled seal mounted in contact with the liquid, between the 

wall of the storage vessel and the floating roof, and extending 

continuously around the circumference of the tank. 

(ii) Two seals mounted one above the other, so that each forms a 

continuous closure that completely covers the space between the 

wall of the storage vessel and the edge of the internal floating 

roof. The lower seal may be vapor-mounted, but both must be 

continuous. 

(iii) A mechanical shoe seal. A mechanical shoe seal is a metal sheet 

held vertically against the wall of the storage vessel by springs or 

weighted levers and is connected by braces to the floating roof. A 
3745-21-21 3 

flexible coated fabric (envelope) spans the annular space between 

the metal sheet and the floating roof. 

(c) Automatic bleeder vents shall be equipped with a gasket and are to be 

closed at all times when the roof is floating except when the roof is 

being floated off or is being landed on the roof leg supports. Rim space 

vents shall be equipped with a gasket and are to be set to open only 

when the internal floating roof is not floating or at the manufacturer's 

recommended setting. 

(d) Each opening in a non-contact internal floating roof, except for automatic 

bleeder vents (vacuum breaker vents) and the rim space vents, shall 

provide a projection below the liquid surface. 

(e) Each opening in the internal floating roof, except for leg sleeves, 

automatic bleeder vents, rim space vents, column wells, ladder wells, 

sample wells, and stub drains, shall be equipped with a cover or lid 

which shall be maintained in a closed position at all times (i.e., no 

visible gap) except when the device is in actual use. The cover or lid 

shall be equipped with a gasket. Covers on each access hatch and 

automatic gauge float well shall be bolted except when they are in use. 

(f) The sample well, which penetrates the internal floating roof for the 

purpose of sampling, shall have a slit fabric cover that covers at least 

ninety per cent of the opening. 

(g) Each penetration of the internal floating roof that allows for passage of a 

ladder shall have a gasketed sliding cover. 

(h) Inspection requirements. 

The owner or operator of each storage vessel equipped with an internal 

floating roof, shall comply with the following inspection requirements: 

(i) Visually inspect the internal floating roof, the primary seal, and the 

secondary seal (if one is in service), prior to filling the storage 

vessel with a volatile organic liquid. If there are holes, tears, or 

other openings in the primary seal, the secondary seal, or the seal 

fabric, or defects in the internal floating roof, or both, the owner 

or operator shall repair the items before filling the storage vessel. 

(ii) For vessels equipped with a liquid-mounted or mechanical shoe 

primary seal, visually inspect the internal floating roof and the 
3745-21-21 4 

primary seal or the secondary seal (if one is in service) through 

manholes and roof hatches on the fixed roof at least once every 

twelve months after initial fill. If the internal floating roof is not 

resting on the surface of the volatile organic liquid inside the 

storage vessel, or there is liquid accumulated on the roof, or the 

seal is detached, or there are holes or tears in the seal fabric, the 

owner or operator shall repair the items or empty and remove the 

storage vessel from service within forty-five days. If a failure that. 

is detected during inspections required in this paragraph cannot be 

repaired within forty-five days and if the vessel cannot be emptied 

within forty-five days, a thirty-day extension may be requested 

from the director in the inspection report required in paragraph 

(C)(3)(j)(iii) of this rule. Such a request for an extension must 

document that alternate storage capacity is unavailable and 

specify a schedule of actions the company will take that will 

ensure that the control equipment will be repaired or the vessel 

will be emptied within thirty days. 

(iii) For vessels equipped with both primary and secondary seals: 

(a) Visually inspect the vessel as specified in paragraph 

(C)(3)(h)(iv) of this rule at least every five years; or 

(b) Visually inspect the vessel at least once every twelve months 

as specified in paragraph (C)(3)(h)(ii) of this rule. 

(iv) Visually inspect the internal floating roof, the primary seal, the 

secondary seal (if one is in service), gaskets, slotted membranes 

and sleeve seals (if any) each time the storage vessel is emptied 

and degassed. If the internal floating roof has defects, the primary 

seal has holes, tears, or other openings in the seal or the seal 

fabric, or the secondary seal has holes, tears, or other openings in 

the seal or the seal fabric, or the gaskets no longer close off the 

liquid surfaces from the atmosphere, or the slotted membrane has 

more than ten per cent open area, the owner or operator shall 

repair the items as necessary so that none of the conditions 

specified in this paragraph exist before refilling the storage vessel 

with a volatile organic liquid. In no event shall inspections 

conducted in accordance with this provision occur at intervals 

greater than ten years in the case of vessels conducting the annual 

visual inspection as specified in paragraphs (C)(3)(h)(ii) and 

(C)(3)(h)(iii)(h) of this rule and at intervals no greater than five 

years in the case of vessels specified in paragraph (C)(3)(h)(iii)(a) 

of this rule. 
3745-21-21 5 

(i) Notify the director in writing at least thirty days prior to the filling or 

refilling of each storage vessel for which an inspection is required by 

paragraphs (C)(3)(h)(i) and (C)(3)(h)(iv) of this rule to afford the 

director or fl:i.t! the director's authorized designee the opportunity to have 

an observer present. If the inspection required by paragraph 

(C)(3)(h)(iv) of this rule is not planned and the owner or operator could 

not have known about the inspection thirty days in advance of refilling 

the tank, the owner or operator shall notify the director at least seven 

days prior to the refilling of the storage vessel. Notification shall be 

made by telephone immediately followed by written documentation 

demonstrating why the inspection was unplanned. Alternatively, this 

notification including the written documentation may be made in 

writing and sent by express mail so that it is received by the director at 

least seven days prior to the refilling. 

U) Record keeping and reporting requirements. 

The owner or operator of each storage vessel equipped with an internal 

floating roof shall keep records and furnish reports in accordance with 

the following: 

(i) Furnish the director with a report that describes the control 

equipment and certifies that the control equipment meets the 

specifications of paragraph (C) of this rule. This report shall be 

submitted in accordance with the requirements specified in 

paragraph (H) of this rule. 

(ii) Keep a record of each inspection performed as required by 

paragraphs (C)(3)(h)(i) to (C)(3)(h)(iv) of this rule. Each record 

shall identify the storage vessel for which the inspection was 

performed and shall contain the date the vessel was inspected and 

the observed condition of each component of the control 

equipment (seals, internal floating roof, and fittings). 

(iii) If any of the conditions described in paragraph (C)(3)(h)(ii) of this 

rule are detected during the annual visual inspection required by 

paragraph (C)(3)(h)(ii) of this rule, a report shall be furnished to 

the director within thirty days of the inspection. Each report shall 

identify the storage vessel, the nature of the defects, and the date 

the storage vessel was emptied or the nature of and date the repair 

was made. 

(k) After each inspection required by paragraph (C)(3)(h)(iii) of this rule that 
3745-21-21 6 

finds holes or tears in the seal or seal fabric, or defects in the internal 

floating roof, or other control equipment defects listed in paragraph 

(C)(3)(h)(ii) or (C)(3)(h)(iv) of this rule, a report shall be furnished to 

the director within thirty days of the inspection. The report shall 

identify the storage vessel and the reason it did not meet the 

specifications of paragraph (C)(3) of this rule and list each repair made. 

(1) The owner or operator shall keep copies of all reports and records required 

by paragraph (C)(3)(j) ofthis rule for at least five years. 

( 4) If the fixed roof tank is equipped with a closed vent system and control device, 

as required by paragraph (C)(l)(b) or (C)(2) of this rule, the following 

specifications shall be met: 

(a) The closed vent system shall be designed to collect all VOC vapors and 

gases discharged from the storage vessel and operated with no 

detectable emissions, as indicated by an instrument reading of less than 

five hundred parts per million above background and visual inspections, 

as determined by the methods specified in 40 CFR 60.485( c). 

(b) If a control device other than a flare is employed, the control device shall 

be designed and operated to reduce inlet VOC emissions by ninety five 

per cent or greater. The control efficiency shall be detennined in 

accordance with paragraph (C) of rule 3745-21-10 of the 

Administrative Code. 

(c) If a flare is used as the control device, it shall meet the specifications 

described in the general control device requirements specified in 40 

CFR 60.18. 

(d) The owner or operator of each tank that is equipped with a closed vent 

system and control device other than a flare, to meet the control 

requirements as required in paragraph (C)(4) of this rule, shall meet the 

specifications identified in paragraphs (C)(4)(a) and (C)(4)(b) of this 

rule and shall submit, for approval by the director, an operating plan 

containing the information listed below: 

(i) Documentation demonstrating that the control device will achieve 

the required control efficiency during maximum loading 

conditions. This documentation is to include a description of the 

gas stream which enters the control device, including flow and 

VOC content under varying liquid level conditions (dynamic and 

static) and manufacturer's design specifications for the control 
3745-21-21 7 

device. If the control device or the closed vent capture system 

receives vapors, gases, or liquids other than fuels from sources 

that are not designated sources under this rule, the efficiency 

demonstration is to include consideration of all vapors, gases, and 

liquids received by the closed vent capture system and control 

device. If an enclosed combustion device with a minimum 

residence time of 0. 7 5 seconds and a minimum temperature of 

eight hundred sixteen degrees centigrade is used to meet the 

ninety-five per cent control requirement, documentation that those 

conditions will exist during all loading conditions is sufficient to 

meet the requirements of this paragraph. 

(ii) A description of the parameter or parameters to be monitored to 

ensure that the control device will be operated in conformance 

with its design and an explanation of the criteria used for 

selection of that parameter (or parameters). 

(e) Operate the closed vent system and control device and monitor the 

parameters of the closed vent system and control device in accordance 

with the operating plan submitted to the director in accordance with 

paragraph (C)(4)(d) of this rule, unless the plan was modified by the 

director during the review process, in which case, the modified plan 

applies. The operating plan required by paragraph (C)(4)(d) of this rule 

shall be maintained by the owner or operator for the life of the control 

equipment and shall be made available to the director upon request. 

(f) Any approval granted by the director in accordance with paragraph 

(C)( 4)( d) of this rule must be approved by the USEPA as a revision of 

the Ohio state implementation plan. 

(g) The owner or operator of each source that is equipped with a closed vent 

system and a flare, to meet the control requirements in paragraphs 

(C)(4)(a) and (C)(4)(c) of this rule, shall meet the requirements as 

specified in the general control device requirements of 40 CFR 60.18( e) 

and (f).

paragraph (C)(4)(h)(ii)(b) of this rule during which the pilot 

flame was absent shall be furnished to the director. These 

reports shall be submitted to the appropriate Ohio 

environmental protection agency district office or local air 

agency by July fifteenth and January fifteenth of each 

calendar year and shall cover the previous six-month period. 

(i) The owner or operator shall keep copies of all reports and records required 

by paragraph (C)( 4)(h) of this rule for at least five years. 

( 5) A fixed roof tank with a capacity less than forty thousand gallons is exempt 

from the requirements of paragraphs (C)(l) and (C)(2) of this rule. 

(D) Storage of volatile organic liquids in external floating roof tanks. 

(1) Except where exempted under paragraph (D)(2) of this rule, no owner or 

operator of an external floating roof tank shall place, store, or hold any 

volatile organic liquid in any such tank, after the date specified in paragraph 

(F) of this rule, unless: 

(a) Each external floating roof is equipped with a closure device between the 

wall of the storage vessel and the roof edge. The closure device is to 

consist of two seals, one above the other. The lower seal is referred to 
3745-21-21 9 

as the primary seal, and the upper seal is referred to as the secondary

a gasketed cover, seal, or lid that is to be maintained in a closed 

position at all times (i.e., no visible gap) except when the device is in 

actual use. Automatic bleeder vents are to be closed at all times when 

the roof is floating except when the roof is being floated off or is being 

landed on the roof leg supports. Rim vents are to be set to open when 

the roof is being floated off the roof leg supports or at the 

manufacturer's recommended setting. Automatic bleeder vents and rim 

space vents are to be gasketed. Each emergency roof drain is to be 

provided with a slotted membrane fabric cover that covers at least 

ninety percent of the area of the opening. 

(c) The roof shall be floating on the liquid at all times (i.e., off the roof leg 

supports) except when the tank is completely emptied and subsequently 

refilled. The process of filling, emptying, or refilling when the roof is 

resting on the leg supports shall be continuous and shall be 

accomplished as rapidly as possible. 

(2) The following external floating roof tanks shall be exempted from the 

requirements of paragraph (D)(l) of this mle: 

(a) Any tank that has a capacity ofless than forty thousand gallons; or

maximum true vapor pressure less than 0.75 pounds per square inch 

absolute. 

(3) Inspection and measurement requirements. 

The owner or operator of an external floating roof tank shall: 

(a) Determine the gap areas and maximum gap widths between the primary 

seal and the wall of the storage vessel and between the second seal and 

the wall of the storage vessel according to the following frequency: 

(i) Measurements of gaps between the tank wall and the primary seal 

(seal gaps) shall be performed during the hydrostatic testing of the 

vessel or within sixty days of the initial fill with a volatile organic 

liquid and at least every five years thereafter; 

(ii) Measurements of gaps between the tank wall and the secondary seal 

shall be perfonned within sixty days of the initial fill with a 

volatile organic liquid and at least once per year thereafter; and 

(iii) If any source ceases to store a volatile organic liquid for a period of 

one year or more, subsequent introduction of a volatile organic 

liquid into the vessel shall be considered an initial fill for the 

purposes of paragraphs (D)(3)(a)(i) and (D)(3)(a)(ii) of this rule. 

(b) Determine gap widths and areas in the primary and secondary seals 

individually according to the following procedures: 

(i) Measure the seal gaps, if any, at one or more floating roof levels 

when the roof is floating off the roofleg supports. 

(ii) Measure the seal gaps around the entire circumference of the tank, 

in each place where a one-eighth ( 118) inch diameter uniform 

probe passes freely (without forcing or binding against the seal) 

between the seal and the wall of the storage vessel, and measure 

the circumferential distance of each such location. 

(iii) The total surface area of each gap described in paragraph (D)(b )(ii) 

of this rule shall be determined by using probes of various widths 

to measure accurately the actual distance from the tank wall to the 
3745-21-21 11 

seal and then multiplying each such width by its respective 

circumferential distance. 

(iv) Add the gap surface area of each gap location for the primary seal 

and the secondary seal individually and divide the sum for each 

by the nominal diameter of the tank and compare each ratio to the 

respective standards in paragraph (D)(3)(c)(i) or (D)(3)(c)(ii) of 

this rule. 

(c) Make necessary repairs or empty the storage vessel within forty-five days 

of identification in any inspection for seals not meeting the following 

requirements~ listeEl irt ~aragrf!j'lhs (D)(3)(e)(i) lffiS (D)(3)(e)(ii) ef this

Equations in table 2 calculate the monomer VOC emission rate 

value in kilograms of VOC per megagrams of resin or gel coat 

applied. To convert the monomer VOC emission rate to pounds 

per ton multiply the product of the equation by two. The 

equations for vacuum bagging with roll-out are applicable when a 

facility rolls out the applied resin and fabric prior to applying the 

vacuum bagging materials. The equations for vacuum bagging 

without roll-out are applicable when a facility applies the vacuum 

bagging materials immediately after resin application without 

rolling out the resin and fabric. VOC per cent equals VOC content 

as supplied, expressed as a weight-per cent value between zero 

and one hundred per cent.

either the actual annual average emissions prior to when the actual 

reduction occurs or the allowable emissions. A shutdown is creditable 

only to the extent that the owner or operator can demonstrate to the 
3745-110-03 7 

satisfaction of the director that the shutdown does not correspond to 

load-shifting or other activity which results in or could result in an 

equivalent or greater emission increase and that the reduction accounts 

for any increase in NOx emissions from other sources as a result of the 

shutdown. 

(f) Owners or operators must submit a report to the director by March 

thirty-first of each year demonstrating that the equivalent reduction 

requirement in paragraph (H)(l)(c) of rule 3745-110-03 of the
