9VAC5-20-50. Variances. 

A. Fuel variance. 

1. Regardless of any other provision of this section, the executive director may issue an order 

granting a fuel variance for fuel burning equipment from applicable provisions of these regulations 

if, after a thorough investigation and public hearing, he finds that: 

a. The owner, in good faith and prior to the request for the fuel variance, has attempted to 

comply with applicable provisions of these regulations; 

b. The owner has substantial cause to believe he will be unable to obtain the fuel to operate the 

equipment in compliance with applicable provisions of these regulations; 

c. The maximum particulate and sulfur dioxide emissions from fuels permitted in the fuel 

variance would be the lowest that the available fuels will permit; 

d. The need for the requested fuel variance could not have been avoided by the owner; and 

e. The period of the fuel variance will not exceed the reasonably predicted shortage of fuel 

which would allow compliance with these regulations, or 180 days, whichever is less. 

2. The owner requesting the fuel variance shall submit the following, where appropriate, to the 

executive director: 
a. The requested commencement and termination dates of the fuel variance; 

b. The type and quantity of fuel to be used under the requested fuel variance, along with the 

maximum ash and sulfur content, if any; 

c. An affidavit stating why the owner is unable to, or has substantial cause to believe that he will 

be unable to, obtain fuel which would allow compliance with applicable provisions of these 

regulations; 

d. An estimate of the amount of fuel to be conserved; 

e. An estimate of the increased air pollutants that might cause violations of the ambient air 

quality standards; 

f. An estimate, with reasons given, of the duration of the shortage of fuel which would allow 

compliance with applicable provisions of these regulations; and 

g. Such other information as the executive director may require to make his findings as 

provided in subdivision 1 of this subsection. 

3. Notice of public hearings on applications for fuel variances shall be advertised at least 10 days 

prior to the date of the hearing, in at least one major newspaper of general circulation in the air 

quality control region in which the affected source is located. The notice shall contain the subject, 

date, time and place of the public hearing. The public hearing shall be conducted to give the public 

an opportunity to comment on the variance. 

4. Fuel variances may be granted only for individual sources, and not for categories or classes. 

5. No fuel variance shall be granted for more than 180 days. Any request for a variance for a 

period beyond 180 days shall be governed by the provisions of 9VAC5-170-140, except that the 

board, where appropriate, may require compliance with any of the conditions and requirements 

here. 

6. Fuel variances may be amended or revoked in the manner provided for in 9VAC5-170-140 

except that only a 10-day notice shall be required. 
B. Nothing in this section shall be construed to limit, alter or otherwise affect the obligation of any 

person to comply with any provision of these regulations not specifically affected by this section.

9VAC5-20-70. Circumvention. 

A. No owner or other person shall cause or permit the installation or use of any device or any means 

which, without resulting in reduction in the total amount of air pollutants emitted, conceals or dilutes an 

emission of air pollutants which would otherwise violate this chapter. Such concealment includes, but is 

not limited to, either of the following: 

1. The use of gaseous diluents to achieve compliance with a visible emissions standard or with a 

standard which is based on the concentration of a pollutant in the gases discharged to the 

atmosphere. 

2. The piecemeal carrying-out of an operation to avoid coverage by a standard that applies only to 

operations larger than a specified size. 

B. This section does not prohibit the construction of a stack.

9VAC5-20-180. Facility and control equipment maintenance or malfunction. 

A. The provisions of this section apply to periods of excess emissions resulting from (i) the shutdown 

or bypassing, or both, of air pollution control equipment for necessary scheduled maintenance and (ii) 

malfunctions or other equipment failures of any affected facility or related air pollution control equipment. 

B. In case of shutdown or bypassing, or both, of air pollution control equipment for necessary 

scheduled maintenance which results in excess emissions for more than one hour, the intent to shut 

down such equipment shall be reported to the board and local air pollution control agency, if any, at least 

24 hours prior to the planned shutdown. Such prior notice shall include, but is not limited to, the following: 
1. Identification of the specific facility to be taken out of service as well as its location and permit or 

registration number; 

2. The expected length of time that the air pollution control equipment will be out of service; 

3. The nature and quantity of emissions of air pollutants likely to occur during the shutdown period; 

and 

4. Measures that will be taken to minimize the length of the shutdown and to negate the effect of 

the outage of the air pollution control equipment. 

C. In the event that any affected facility or related air pollution control equipment fails or malfunctions 

in such a manner that may cause excess emissions for more than one hour, the owner shall, as soon as 

practicable but no later than four daytime business hours after the malfunction is discovered, notify the 

board by facsimile transmission, telephone or telegraph of such failure or malfunction and shall within two 

weeks provide a written statement giving all pertinent facts, including the estimated duration of the 

breakdown. Owners subject to the requirements of 9VAC5-40-50 C and 9VAC5-50-50 C are not required 

to provide the written statement prescribed in this subsection for facilities subject to the monitoring 

requirements of 9VAC5-40-40 and 9VAC5-50-40. When the condition causing the failure or malfunction 

has been corrected and the facility or control equipment is again in operation, the owner shall notify the 

board. 

D. In the event that the breakdown period cited in subsection C of this section exists or is expected to 

exist for 30 days or more, the owner shall, as expeditiously as possible but no later than 30 days after the 

failure or malfunction and semi-monthly thereafter until the failure or malfunction is corrected, submit to 

the board a written report containing the following: 

1. Identification of the specific facility that is affected as well as its location and permit or 

registration number; 

2. The expected length of time that the air pollution control equipment will be out of service; 

3. The nature and quantity of air pollutant emissions likely to occur during the breakdown period; 
4. Measures to be taken to reduce emissions to the lowest amount practicable during the 

breakdown period; 

5. A statement as to why the owner was unable to obtain repair parts or perform repairs which 

would allow compliance with the Regulations for the Control and Abatement of Air Pollution within 

30 days of the malfunction or failure; 

6. An estimate, with reasons given, of the duration of the shortage of repairs or repair parts which 

would allow compliance with the Regulations for the Control and Abatement of Air Pollution; and 

7. Any other pertinent information as may be requested by the board. 

E. The provisions of subsection D of this section shall not apply beyond three months of the date of 

the malfunction or failure. Should the breakdown period exist past the three-month period, the owner may 

apply for a variance in accordance with 9VAC5-20-50 A. 

F. The following special provisions govern facilities which are subject to the provisions of Article 5 

(9VAC5-50-400 et seq.) of 9VAC5 Chapter 50, Article 1 (9VAC5-60-60 et seq.) of 9VAC5 Chapter 60, or 

Article 2 (9VAC5-60-90 et seq.) of 9VAC5 Chapter 60: 

1. For sources subject to the applicable subparts listed in 9VAC5-50-410, any provisions governing 

malfunctions shall be implemented through this section. In cases where there are differences 

between the provisions of this section and the provisions of 40 CFR Part 60, the more restrictive 

provisions shall apply. 

2. For sources subject to the applicable subparts listed in 9VAC5-60-70, any provisions governing 

malfunctions shall be implemented through this section. In cases where there are differences 

between the provisions of this section and the provisions of 40 CFR Part 61, the more restrictive 

provisions shall apply. 

3. For sources subject to the applicable subparts listed in 9VAC5-60-100, any provisions governing 

malfunctions shall be implemented through this section. In cases where there are differences 

between the provisions of this section and the provisions of 40 CFR Part 63, the more restrictive 
provisions shall apply. 

G. No violation of applicable emission standards or monitoring requirements shall be judged to have 

taken place if the excess emissions or cessation of monitoring activities is due to a malfunction, provided 

that: 

1. The procedural requirements of this section were met or the owner has submitted an acceptable 

application for a variance, which is subsequently granted; 

2. The owner has taken expeditious and reasonable measures to minimize emissions during the 

breakdown period; 

3. The owner has taken expeditious and reasonable measures to correct the malfunction and 

return the facility to a normal operation; and 

4. The source is in compliance at least 90% of the operating time over the most recent 12-month 

period. 

H. Nothing in this section shall be construed as giving an owner the right to increase temporarily the 

emission of pollutants or to circumvent the emission standards or monitoring requirements otherwise 

provided in the Regulations for the Control and Abatement of Air Pollution. 

I. Regardless of any other provision of this section, the owner of any facility subject to the Regulations 

for the Control and Abatement of Air Pollution shall, upon request of the board, reduce the level of 

operation at the facility if the board determines that this is necessary to prevent a violation of any primary 

ambient air quality standard. Under worst case conditions, the board may order that the owner shut down 

the facility, if there is no other method of operation to avoid a violation of the primary ambient air quality 

standard. The board reserves the right to prescribe the method of determining if a facility will cause such 

a violation. In such cases, the facility shall not be returned to operation until it and the associated air 

pollution control equipment are able to operate without violation of any primary ambient air quality 

standard. 

J. Any owner of an affected facility subject to the provisions of this section shall maintain records of 
the occurrence and duration of any bypass, malfunction, shutdown or failure of the facility or its 

associated air pollution control equipment that results in excess emissions for more than one hour. The 

records shall be maintained in a form suitable for inspection and maintained for at least two years (unless 

a longer period is specified in the applicable emission standard) following the date of the occurrence.

9VAC5-20-220. Shutdown of a stationary source. 

A. Upon a final decision by the board that a stationary source or emissions unit is shut down 

permanently, the board shall revoke any permits by written notification to the owner and remove the 

stationary source or emissions unit from the emission inventory or consider its emissions to be zero in any 

air quality analysis conducted; and the stationary source or emissions unit shall not commence operation 

without a permit being issued under the applicable provisions of 9VAC5 Chapter 80 (9VAC5-80-10 et 

seq.). 

B. The final decision shall be rendered as follows: 

1. Upon a determination that the stationary source or emissions unit has not operated for a year or 

more, the board shall provide written notification to the owner (i) of its proposed decision that the 

stationary source or emissions unit is considered to be shut down permanently and (ii) that if the 

owner fails to provide within three months of the notice written response to the board that the 

shutdown is not to be considered permanent, the decision shall become final within six months of 

the notice. The response from the owner shall include the basis for the assertion that the shutdown 
is not to be considered permanent and a projected date for restart-up of the stationary source or 

emissions unit. 

2. If the board should find that the basis for the assertion is not sound or the projected restart-up 

date allows for an unreasonably long period of inoperation, the decision to consider the shutdown 

permanent shall become final one year after the date of the notice of the proposed decision. 

C. Nothing in any regulation of the board shall be construed to prevent the board and the owner from 

making a mutual determination that a stationary source or emissions unit is shut down permanently prior 

to any final decision rendered under subsection B of this section.

9VAC5-20-230. Certification of documents. 

A. The following documents submitted to the board shall be signed by a responsible official: (i) any 

emission statement, application, form, report, or compliance certification; (ii) any document required to be 

so signed by any provision of the regulations of the board; or (iii) any other document containing 

emissions data or compliance information the owner wishes the board to consider in the administration of 

its air quality programs. A responsible official is defined as follows: 

1. For a business entity, such as a corporation, association or cooperative, a responsible official is 

either: 

a. The president, secretary, treasurer, or a vice president of the business entity in charge of a 

principal business function, or any other person who performs similar policy or decision-making 

functions for the business entity; or 

b. A duly authorized representative of such business entity if the representative is responsible 

for the overall operation of one or more manufacturing, production, or operating facilities 
applying for or subject to a permit and either (i) the facilities employ more than 250 persons or 

have gross annual sales or expenditures exceeding $25 million (in second quarter 1980 dollars) 

or (ii) the authority to sign documents has been assigned or delegated to such representative in 

accordance with procedures of the business entity. 

2. For a partnership or sole proprietorship, a responsible official is a general partner or the 

proprietor, respectively. 

3. For a municipality, state, federal, or other public agency, a responsible official is either a 

principal executive officer or ranking elected official. A principal executive officer of a federal 

agency includes the chief executive officer having responsibility for the overall operations of a 

principal geographic unit of the agency. 

B. Any person signing a document under subsection A of this section shall make the following 

certification: 

"I certify under penalty of law that this document and all attachments were prepared under my 

direction or supervision in accordance with a system designed to assure that qualified personnel 

properly gather and evaluate the information submitted. Based on my inquiry of the person or 

persons who manage the system, or those persons directly responsible for gathering and 

evaluating the information, the information submitted is, to the best of my knowledge and belief, 

true, accurate, and complete. I am aware that there are significant penalties for submitting false 

information, including the possibility of fine and imprisonment for knowing violations." 

C. Subsection B of this section shall be interpreted to mean that the signer must have some form of 

direction or supervision over the persons gathering the data and preparing the document (the preparers), 

although the signer need not personally nor directly supervise these activities. The signer need not be in 

the same line of authority as the preparers, nor do the persons gathering the data and preparing the form 

need to be employees (e.g., outside contractors can be used). It is sufficient that the signer has authority 

to assure that the necessary actions are taken to prepare a complete and accurate document. 

D. Any person who fails to submit any relevant facts or who has submitted incorrect information in a 
document shall, upon becoming aware of such failure or incorrect submittal, promptly submit such 

supplementary facts or corrected information.
