considerations, and handling procedures.

"Modification" means any physical change in, or change in the method of 

operation of, a stationary source which increases the actual emission rate of 

any air contaminant, regardless of any emission reductions achieved at the 

source. A physical change or change in the method of operation shall not 

include:

(a) Routine maintenance, repair and replacement; or

unless such change is prohibited under any condition of a permit 

issued pursuant to these Regulations.

"Most Stringent Emission Rate (MSER)" a rate of emissions which the 

Secretary, on a case-by-case basis, determines is achievable for a source 

based on the lowest emission rate achieved in practice by such category of 

source, unless the source demonstrates it cannot achieve such a rate due to 

economic impacts and costs. Costs of achievement of MSER will be accorded 

less weight for sources or modifications locating in non-attainment areas

than for sources or modifications locating in attainment areas for the 

applicable air contaminant. In no event shall application of MSER result in 

emissions of any contaminants in excess of any federal emission standard or

any emission standard contained in these regulations. If the Secretary

(1) Industrial Process Emissions

(a) No person shall discharge, cause, suffer, allow, or permit in any 

one hour from any stack whatsoever particulate matter in excess 

of the amount shown in Table 1. For purposes of this regulation 

the total process weight entering a process unit shall be used to 

determine the maximum allowable emissions of particulate matter

which may pass through the stack associated with the process 

unit. When two or more process units exhaust through a common 

stack, the combined process weight of all of the process units, 

served by the common stack, shall be used to determine the 

allowable particulate matter emission rate.

(b) In cases where process weight is not applicable as determined by 

the Air Pollution Control Officer, the concentration of 

particulate matter in the effluent gas stream shall not exceed 

0.14 grams per cubic meter (0.06 grains per cubic foot) of 

undiluted exhaust gas at standard conditions on a dry basis. In 

the case of wood processing operations, process weight is not 

applicable, and instead, the concentration standard specified in 

this subsection shall apply.

(2) Incinerator Emissions

(a) A person shall not discharge, cause, suffer, allow, or permit the 

emission of particulate matter from any incinerator with a 

designed charging rate of less than 45.36 metric tons (50 tons)

per day and which is not a crematory, to exceed 0.05 kilograms 

(0.10 pounds) per 43.36 kilograms (100 pounds) of refuse burnt. 

All incinerators built and installed after July 1, 1971, shall be 

multiple chamber incinerators or equipment found by the Air 
VAPCR Adopted September 2011 [38]

Pollution Control Officer, in advance of such use, to be equally 

effective for the purpose of air pollution control as an approved 

multiple chamber incinerator. The responsibility for showing that 

the equipment other than a multiple chamber incinerator is in 

compliance with the emission limits of this subsection shall be 

on the person seeking to come within the provisions of this 

subsection.

(b) Any incinerators with a designed charging rate of 45.36 metric 

tons (50 tons) per day or more shall be operated in such a manner 

that emissions of particulate matter shall not exceed 0.183 grams 

per dry standard cubic meter (0.08 grains per dry standard cubic 

foot) corrected to 12 percent carbon dioxide.

(c) A person shall not discharge, cause, suffer, permit, or allow to 

be emitted from any crematory any gases that contain particulate 

matter in excess of 0.14 grams per dry standard cubic meter (0.06 

grains per dry standard cubic foot), corrected to 7 percent 

oxygen. The owner or operator of a crematory installed after June 

1, 1995 shall ensure that the last combustion chamber or zone of 

the crematory is preheated to a temperature of at least 1,600 

degrees Fahrenheit prior to introduction of the charge. All 

sampling runs conducted as a part of emission tests intended to 

demonstrate compliance with the emission limit specified in this 

subsection shall begin when waste material is first introduced 

into the crematory.

(d) Any incinerator which is designed or operated primarily for the 

purpose of producing heat or power may be designated as fuel 

burning equipment by the Air Pollution Control Officer. An 

incinerator so designated shall be subject to the emission

limitations set forth in subsection(3)(a) of this section, 

concerning combustion contaminants.

(3) Combustion Contaminants

(a) A person shall not discharge, cause, suffer, allow or permit the 

emission of particulate matter caused by the combustion of fossil 

fuel in fuel burning equipment from any stack or chimney in 

excess of the following emission limits:

(i) 0.5 pounds per hour per million BTU's of heat input in 

combustion installations where the heat input is 10 million 

BTU's or less per hour.

(ii) For combustion installations where the heat input is 

greater than 10 million BTU's per hour, but where the heat 

input is equal to or less than 250 million BTU's per hour, 

the applicable limit is determined by using the following 

formula:

[ 0.47039 (log ) 0.16936]   1 0 



HI EPM 10

where:
VAPCR Adopted September 2011 [39]

EPM - is the particulate matter emission limit, expressed 

to the nearest hundredth pound per hour per million 

BTU's; and

HI - is the heat input in millions of BTU's per hour.

(iii) 0.1 pounds per hour per million BTU's of heat input in 

installations where the heat input is greater than 250 

million BTU's per hour, but where the heat input is equal 

to or less than 1000 million BTU's per hour.

(iv) 0.06 pounds per hour per million BTU's of heat input in 

installations where the heat input is greater than 1000 

million BTU's per hour.

(b) A person shall not discharge, cause, suffer, allow, or permit the 

emission of particulate matter caused by the combustion of wood

fuel in fuel burning equipment from any stack or chimney:

(i) In excess of 0.45 grains per dry standard cubic foot 

(gr/DSCF) of exhaust gas corrected to 12% CO2 in any 

combustion installation that has a rated output of greater 

than 90 H.P. which commenced operation prior to December 5, 

1977.

(ii) In excess of 0.20 gr/DSCF corrected to 12% CO2 in any 

combustion installation that has a rated output of greater 

than 90 H.P., but less than 1300 H.P., which commences 

operation after December 5, 1977.

(iii) In excess of 0.10 gr/DSCF corrected to 12% CO2 in any 

combustion installation that has a rated output of 1300 

H.P. or greater which commences operation after December 5, 

1977.

Any wood fuel burning equipment that has a rated output of 90 

H.P. or less shall not be subject to these particulate matter

emission standards. 

When any fossil fuel is burned in combination with wood fuel, and 

the fossil fuel contributes less than 50% of the total BTU input, 

the above particulate matter standards shall apply. If the fossil 

fuel contributes more than 50% of the total BTU input, subsection 

(3)(a) of this regulation shall apply.

When a soot blowing cycle exceeds 15 minutes, separate emissions

testing for particulate matter emissions during the soot blowing 

cycle may be required in addition to emissions testing during 

normal operating conditions pursuant to Regulation 5-404 below. 

In this event, the emission rate calculated for the soot blowing 

cycle shall be prorated over the time period between soot blowing 

cycles.
VAPCR Adopted September 2011 [40]

(c) The emission standards in this regulation apply to installations 

in which fuel is burned for the primary purpose of producing 

steam, hot water, hot air or other liquids, gases, or solids, and 

in the course of doing so, the products of combustion do not come 

into direct contact with the process material. Fuel includes 

coal, coke, lignite, fuel oil, wood, and combustible refuse. When 

any product or byproducts of a manufacturing process are burned

for said purpose, or in conjunction with any fuel, the emission

standards above shall apply.

(4) Fugitive Particulate Matter

A person shall not cause, suffer, allow, or permit any process 

operation to operate that is not equipped with a fugitive particulate

constituents are bitumens that occur naturally or are obtained as a 

residue of petroleum refining.

"Cutback Asphalt" means asphalt that has been liquefied by blending 

with organic compounds (diluents). Upon exposure to atmospheric 

conditions, the diluents evaporate, leaving the asphalt to perform its 

function.

"Emulsified Asphalt" means an emulsion of asphalt and water that

"Penetrating Prime Coat" means an application of low-viscosity liquid 

asphalt to an absorbent surface. It is used to prepare an untreated 
VAPCR Adopted September 2011 [77]

base for an asphalt surface. The prime coat penetrates the base, plugs 

voids, and hardens and helps bind the top to the overlying asphalt 

course. The penetrating prime coat also reduces the necessity of 

maintaining an untreated base course prior to placing the asphalt 

pavement.

(c) Standards.

(1) No person shall cause, allow, or permit the manufacture, mixing, 

storage, or use of cutback asphalts or emulsified asphalts which

dilution of the coating or contact adhesive.

"Basecoat" means a coat of colored material, usually opaque, that is 

applied before graining inks, glazing coats, or other opaque finishing 

materials, and is usually topcoated for protection.

"Certified Product Data Sheet (CPDS)" means documentation furnished by 

coating or adhesive suppliers or an outside laboratory that provides 

the HAP content of a finishing material, contact adhesive, or solvent,

EPA; the VOC content and solids content of a finishing material, 

strippable booth coating, solvent or contact adhesive, by percent 

weight, measured using EPA Method 24, or an alternative or equivalent 

method approved by the Air Pollution Control Officer; and the density, 

measured by EPA Method 24 or an alternative or equivalent method 

approved by the Air Pollution Control Officer. Therefore, the 

reportable VOC and HAP contents should represent the maximum aggregate 

emissions potential of the finishing material, strippable booth 

coating, adhesive, or solvent in concentrations greater than or equal

continuous coater including spraying, curtain coating, roll coating, 

dip coating, and flow coating.

"Conventional Air Spray" means a spray coating method in which the 

coating is atomized by mixing it with compressed air and applied at an 

air pressure greater than 10 pounds per square inch (gauge) at the 

point of atomization. Airless and air assisted airless spray 

technologies are not conventional air spray because the coating is not 

atomized by mixing it with compressed air. Electrostatic spray 

technology is also not considered conventional air spray because an 

electrostatic charge is employed to attract the coating to the 

workpiece.

or volatile hazardous air pollutant that is used for dissolving or 
VAPCR Adopted September 2011 [80]

dispersing constituents in a coating or contact adhesive, adjusting the 

viscosity of a coating or contact adhesive, or cleaning equipment. When 

used in a coating or contact adhesive, the organic solvent evaporates 

during drying and does not become a part of the dried film. 

"Sealer" means a finishing material used to seal the pores of a wood 

substrate before additional coats of finishing material are applied. 

Special purpose finishing materials that are used in some finishing 

systems to optimize aesthetics are not sealers.

directly to the substrate. It includes, but is not limited to, 

nongrain raising stains, equalizer stains, prestains, sap stains, body 

stains, no-wipe stains, penetrating stains, and toners. 

"Strippable Spray Booth Coating" means a coating that: (1) is applied 

to a spray booth wall to provide a protective film to receive overspray

need to use organic solvents to clean spray booth walls.

"Substrate" means the surface onto which a coating or contact adhesive

is applied (or into which a coating or contact adhesive is 

impregnated).

"Thinner" means a volatile liquid that is used to dilute coatings or 

contact adhesives (to reduce viscosity, color strength, and solids, or 

to modify drying conditions).

having a solids content by weight of 12.0 percent by weight or less. 

Washcoats are applied over initial stains to protect, to control color, 

and to stiffen the wood fibers in order to aid sanding. 

"Washoff Operations" means those operations in which organic solvent is 

used to remove coating from wood furniture or a wood furniture 

component.

"Wood Furniture" means any product made of wood, a wood product such as

5-261 CONTROL OF HAZARDOUS AIR CONTAMINANTS

(1) Applicability

(a) No person shall discharge, or cause or allow the discharge of, 

emissions of any hazardous air contaminant, except in conformity 

with the provisions of this section. Any stationary source whose 

actual emission rate of a contaminant is below the Action Level 

for such contaminant specified in Appendix C of these regulations 

shall not be subject to this section for that contaminant. In the 

case of a stationary source with multiple process units, the 

actual emissions of a contaminant from the entire stationary 

source shall be compared to the appropriate Action Level to 

determine the applicability of this section. If the increase in 

emissions from a modification of such a stationary source, in 

conjunction with all other emissions from the source, would 

result in an exceedance of an Action Level, the modification

shall be subject to this section.

(b) The 2007 amendments to Appendix C of these regulations shall take 

effect 15 days after adoption is complete, unless a stationary 

source operating in conformity with the provisions of this 

section and Appendix C in effect prior to the 2007 amendments 

requests an extension by providing the Secretary with an 

alternative timetable and compelling justifications for such 

timetable and the request for the extension is approved by the 

Secretary.
VAPCR Adopted September 2011 [94]

(c) The following categories of air contaminant sources or sources 

engaged in the following activities are exempt from the 

requirements of Section 5-261:

(i) Operations conducted for the purpose of spraying or 

applying agricultural herbicides, pesticides, insecticides, 

or other agricultural chemicals under a program approved by 

the Vermont Department of Agriculture; and

(ii) Solid fuel burning equipment (not including incinerators) 

installed or constructed prior to January 1, 1993, and all 

fuel burning equipment which combusts virgin liquid or 

gaseous fuel.

(2) Hazardous Most Stringent Emission Rate

For each hazardous air contaminant listed in Appendix B herein and 

emitted by a stationary source, the source shall apply control 

technology, production processes or other techniques adequate to 

achieve the hazardous most stringent emission rate (HMSER). Once the 

Secretary has determined HMSER for a stationary source and this 

determination has been included in an order or agreement entered into 

or issued under the authority of the Act, 3 V.S.A. §2822 or other State 

statutes, said determination shall remain in effect for five years, 

unless the source is modified or reconstructed during said five years. 

At the end of said five years, the determination shall expire unless 

the source demonstrates to the Secretary that such emission rate still 

represents HMSER.

(3) Air Quality Impact Evaluation

The Secretary may require any person subject to this section to submit 

to him or her an air quality impact evaluation which shall demonstrate 

whether the actual emissions from the source, in conjunction with

emissions from all other sources, will or will not cause or contribute 

to ambient air concentrations in excess of any Hazardous Ambient Air 

Standard as set forth in Appendix C of these regulations. Said 

evaluation shall be performed in accordance with the Agency's air 

quality impact evaluation guidelines (revised November 20, 1992) and 

shall include an analysis of ambient air monitoring data for each 

contaminant evaluated, if reliable and representative data exists. In 

determining whether such an impact evaluation is warranted, the 

Secretary shall take into consideration the following factors:

(a) The degree of toxicity of the air contaminant and the emission

rate;

(b) The proximity of the source to residences, population centers and 

other sensitive human receptors; and

(c) Emission dispersion characteristics at or near the source, taking 

into account the physical location of the source relative to 

surrounding buildings and terrain.
VAPCR Adopted September 2011 [95]

(4) Hazardous Ambient Air Standards 

No person shall discharge, or cause or allow the discharge of, any 

hazardous air contaminants from a stationary source which cause or 

contribute to ambient air concentrations in excess of any Hazardous 

Ambient Air Standard.

(5) Special Procedures for Contaminants In Appendix C, Category I

(a) Notwithstanding any other provisions of Section 5-261, beginning 

January 1, 1993, no person shall discharge, or cause or allow the 

discharge of, any Appendix C, Category I contaminants from a 

stationary source which would exceed any stationary source

hazardous air impact standard. Emissions subject to this 

subsection shall not be subject to the requirements of 

subsections (3) or (4) of this section.

(b) The Secretary may require the owner or operator of a stationary 

source subject to this section with respect to emissions of any 

Appendix C, Category I contaminant to submit to the Secretary an 

air quality impact evaluation which shall demonstrate whether the 

actual emissions from the subject source will violate subsection 

(5)(a) of this section. Said evaluation shall be performed in 

accordance with the Agency's air quality impact evaluation

guidelines (revised November 20, 1992).

(c) If the Secretary determines, through air quality monitoring, that 

the annual concentration of a contaminant listed in Appendix C, 

Category I has exceeded its hazardous ambient air standard, the 

Secretary shall adopt a Toxic Action Plan (TAP) for the 

contaminant. Each TAP shall contain a strategy to reduce ambient 

air concentrations of the contaminant. The Secretary may also 

adopt TAPs for other hazardous air contaminants.

(6) Interim Standards

(a) If any stationary source emits or proposes to emit a hazardous 

air contaminant which is not listed in Appendix B of these 

regulations, the Secretary shall determine an interim Hazardous 

Ambient Air Standard or interim Stationary Source Hazardous Air 

Impact Standard, if appropriate and an interim Action Level for 

said contaminant, provided that sufficient health data are 

available. In that event, such source shall be subject to all 

requirements of this section in the same manner as if said 

contaminant were listed in Appendices B and C herein. Such 

interim standards shall remain in effect until revised by 

rulemaking or adjusted in accordance with this subsection.

(b) If additional scientific data becomes available that warrants 

adjusting a standard, including default values, for a chemical or 

compound listed in Appendices B and C herein, the data along with

VAPCR Adopted September 2011 [109]

(1) Applicability

(a) This section applies to all major stationary sources and major 

modifications which are constructed subsequent to July 1, 1979 

and are subject to review under Section 5-501 herein.

(b) Where a source is constructed or modified in increments:

(i) Which individually are not subject to review under this 

section,

(ii) Which have not previously been aggregated for purposes of 

their review under this section, and

(iii) Which are not a part of a program of construction or 

modification in planned incremental phases previously 

approved by the Secretary.

All such increments shall be added together for determining the 

applicability of this section.

(2) Prohibition

No person shall initiate construction of any major stationary source or 

major modification until the applicable requirements of this section 

have been complied with and a permit approving construction has been 

issued in accordance with Section 5-501 herein.

(3) Most Stringent Emission Rate

(a) (i) Each major stationary source shall apply control technology 

adequate to achieve the most stringent emission rate with 

respect to those air contaminants for which it would have 

significant allowable emissions.

(ii) Each major modification shall apply control technology 

adequate to achieve the most stringent emission rate with 

respect to any air contaminant for which there would be a 

significant increase in actual emissions at the source, but 

only for those proposed physical or operational changes 

which would contribute to increased emissions of the air 

contaminant.

(b) Any source or modification subject to this section shall submit 

information at the time it applies for approval to construct to 

establish that the most stringent emission rate will be achieved.

(4) Air Quality Impact Evaluation

(a) A source or modification subject to this section with respect to 

any air contaminant other than volatile organic compounds or

greenhouse gases, shall submit to the Secretary an air quality 

impact evaluation at the time it applies for approval to 

construct under Section 5-501 herein. 
VAPCR Adopted September 2011 [110]

(b) Ambient Air Quality Standards review: The evaluation shall 

demonstrate that the increase in allowable emissions will not 

cause a violations of any applicable ambient air quality standard

in any area, and will not significantly contribute to a violation 

of any applicable ambient air quality standard in any area that 

does not or would not meet the applicable ambient air quality 

standard nonattainment area for the above air contaminants. A 

source or modification will be considered to significantly 

contribute to, a violation of any ambient air quality standard

for the above air contaminants if the increase in the allowable 

emissions from the source or modification will cause any increase 

in ambient concentrations of the above air contaminants in any 

area that does not or would not meet the applicable ambient air 

quality standardthe nonattainment area in excess of any of the 

levels of significant impact shown in Table 3 herein. If a source 

or modification will significantly contribute to such a 

violation, the evaluation shall demonstrate that the source or 

modification will comply with the requirements of paragraph (6) 

herein.

(c) Prevention of Significant Deterioration (PSD) Increment review: 

The evaluation shall demonstrate that, as of the source's or 

modification's start-up date, the increase in allowable 

emissions, in conjunction with all other applicable emissions

increases or reductions, will not cause or contribute to any 

increase in ambient concentrations exceeding the remaining 

available prevention of significant deterioration (PSD) increment 

for the specified air contaminants, as determined by the 

Secretary. A demonstration under this paragraph is not required 

if a source is modified, but there is no net increase in the 

source's allowable emissions of the air contaminants specified in 

Table 2.

(d) Sensitive Area review: The evaluation shall demonstrate that the 

increase in allowable emissions will not cause an adverse impact 

on visibility, or interfere with reasonable progress toward 

remedying of existing man-made visibility impairment, in any 

sensitive area. 

(e) Class I Federal Area review: The evaluation shall demonstrate 

that the increase in allowable emissions will not cause an 

adverse impact on visibility or any other Air Quality Related 

Value or in any Class I Federal area. and will not interfere with 

reasonable progress toward the remedying of existing man-made 

visibility impairment in a sensitive area. Said demonstration 

shall be submitted to the Agency and the appropriate Federal Land 

Manager at least 60 days prior to the close of the public comment 

period on the source or modification.

(ef) Any air quality impact evaluation or modeling required by this 

section shall be prepared in accordance with procedures 

acceptable to the Secretary and with Section 5-406 of these 

regulations. The evaluation shall exclude the effect of that 

portion of the height of any stack which exceeds good engineering 

practice and the effect of any other dispersion technique.
VAPCR Adopted September 2011 [111]

(5) Increment Allocation

(a) The evaluation required in paragraph (4)(c) above shall 

demonstrate that the increase in allowable emissions thereunder 

will not consume more than 25% of the remaining annual PSD

increment, nor more than 75% of the remaining 24 hour PSD

increment for the specified air contaminants.

(b) The remaining available PSD increment, in either case, shall be 

determined by the Secretary.

(c) Once a source has demonstrated that it will comply with paragraph 

(5)(a) above, the appropriate portions of the PSD increments 

shall be allocated in accordance with procedures established by 

the Secretary, which may provide for local or regional 

participation.

(6) Emission Reductions

(a) The Secretary shall not issue a permit approving construction of 

any source or modification subject to this section if the source 

or modification is unable to demonstrate, as required under 

Paragraph (4)(b), that the increase in allowable emissions from 

it will not significantly contribute to a violation of any 

applicable ambient air quality standard in a designated 

nonattainment area unless, prior to issuance of any such permit:

(i) The source owner or operator secures legally binding 

offsetting emission reductions of said air contaminant, not 

otherwise to be utilized as part of the State's attainment 

strategies, of the air contaminant contributing to such a 

violation from existing sources located in or impacting on 

the same area (whether or not under the same ownership) 

such as to provide a net emission reduction acceptable to 

the Secretary, and

(ii) The source owner or operator certifies that all existing 

sources of the source owner located in the State are in 

compliance with all applicable rules or are meeting all 

steps of any compliance schedules contained in any 

administrative orders or court decrees.

(b) Regardless of whether a source or modification is subject to the 

requirements of paragraph (6)(a) of this section, the Secretary

shall not issue a permit approving construction of any source or 

modification of nitrogen oxides or volatile organic compounds 

(VOCs) subject to this section and meeting the federal definition 

of major stationary source or major modification contained in 40 

C.F.R. Part §51.165 as applicable to the Ozone Transport Region

unless, prior to issuance of such permit, the owner or operator 

of said source shall:
VAPCR Adopted September 2011 [112]

(i) Secure legally binding offsetting emission reductions (not 

otherwise required by law) of nitrogen oxides or VOCs, as 

applicable, from existing sources;

(ii) Obtain an offset ratio of a minimum of 1.15:1; and

(iii) Certify that all existing sources of the source owner 

located in the state are subject to emissions limitations 

and are in compliance, or on an enforceable schedule for 

compliance with all applicable emissions limitations and 

standards.

(c) Only emission reductions that meet the following criteria shall 

be eligible for use as offsetting emission reductions under 

Section 5-502(6):

(i) Except for ozone precursors, emission reductions of a 

contaminant may only be used to offset emissions of the 

same contaminant. Emission reductions of particulate matter

may only be used to offset emissions of equally or less 

hazardous forms of particulate matter. For the purpose of 

offsetting ozone precursors, emission reductions for 

nitrogen oxides or VOCs can be used to offset emissions of 

each other if approved by the Secretary and EPA on a caseby-case basis;

(ii) Emission reductions must have occurred after January 1, 

1990, or within ten years previous to the date of any 

application under this section in which the reduction is 

proposed to be used, whichever is more recent; and

(iii) The emissions reductions must be emission reductions

credits pursuant to Subsection 5-502(7) or ERCs generated 

in another state where a reciprocal trading agreement has 

been established between Vermont and such other state.

(7) Emission Reduction Credits

(a) The owner or operator of a source at which a reduction in 

emissions of nitrogen oxides or VOCs has occurred may apply to 

the Secretary for certification of the reduction as an emission 

reduction credit (ERC). Ten percent of all actual emission

reductions identified by the owner or operator for certification 

will revert to the Agency for its use as it sees fit. Once 

certified by the Secretary, an ERC may be used to offset 

increased emissions from new or modified sources or for other 

purposes approved by the Secretary.

(b) Only emission reductions that meet the following eligibility 

criteria shall be certified as ERC's:

(i) Emission reductions may be created by shutdown, 

curtailment, or over control of emissions beyond an 
VAPCR Adopted September 2011 [113]

applicable limit, or any other reduction method acceptable 

to the Secretary. 

(ii) Emission reductions shall be real, surplus, quantifiable, 

permanent, and state and federally enforceable.

(iii) Emissions from sources which have been issued permits but 

never operated, or which have engaged in normal operations 

for less than one (1) year, shall not be used as offsetting 

emission reductions.

(iv) Emission reductions may be certified as ERC's only after 

the reductions have actually occurred.

(c) An application for certification shall be submitted within 18 

months after the emission reduction occurs.

(d) In order to confirm emission reductions claimed in conjunction 

with an application for ERC certification, the Secretary may 

require the submission of production, fuel use or other records 

or emissions testing or the use of continuous emissions

monitoring or other appropriate means of measurement. The same or 

an equivalent method of measurement shall be used to quantify 

emissions both before and after the reduction.

(e) Where a reciprocal trading agreement has been established between 

Vermont and another state, ERCs generated in Vermont may be used 

in such other state.

(8) Ambient Air Quality Monitoring

(a) A major stationary source or major modification required to 

submit an air quality impact evaluation shall include in such 

evaluation an analysis of ambient air monitoring data for any 

attainment areas impacted by each of the following air 

contaminants;

(i) For the source, each contaminant for which it would have 

significant allowable emissions;

(ii) For the modification, each contaminant for which it would 

result in a significant increase in actual emissions.

(b) Ambient monitoring data shall be based on sampling conducted for 

a time period of up toat least one year immediately preceding 

submission of any application for approval to construct such a 

source or modification. Ambient monitoring data collected for a 

time period of less than one year, but not less than four (4) 

months, or for a time period other than immediately preceding 

submission of any such application may be acceptable if such data 

is adequate for determining whether the source or modification

will cause a violation of any applicable ambient air quality 

standard or consume more than the remaining available PSD

increment.
VAPCR Adopted September 2011 [114]

(c) Subparagraphs (a) and (b) above shall not apply to any air

contaminant for which no ambient air quality standard has been 

adopted. 

(9) Alternative Site Analysis

Any source or modification subject to this section that would be 

constructed in an area designated as non-attainment for a pollutant for

which the source or modification is major, shall conduct an analysis 

of alternative sites, sizes, production processes and environmental

control techniques for such proposed source that demonstrates that the 

benefits of the proposed source significantly outweigh the 

environmental and social costs imposed as a result of its location, 

construction or modification. 

5-503 [REPEALED] Repealed eff. February 8, 2011.

VAPCR Adopted September 2011 [123]

SUBCHAPTER VIII. REGISTRATION OF AIR CONTAMINANT SOURCES

5-801 DEFINITIONS

"Source" means, for the purposes of this Subchapter only, all stationary 

structures, facilities, equipment, installations, or operations which emit or 

may emit any air contaminant and which are:

(a) Operated by the same person or by persons under common control, 

and

(b) Located on one or more contiguous or adjacent properties where 

all such property is owned by the same person or by persons under 

common control.

(Note that the person or persons operating the source will not 

necessarily be the same person or persons who own the property 

upon which the source is located.)

"Operator" means, for purposes of this Subchapter only, any person operating 

or responsible for the operation of a source.

5-802 REQUIREMENT OF REGISTRATION

Each operator of a source which emits more than five tons of any and all air 

contaminants per year shall register the source with the Secretary, and shall 

renew such registration annually. Each day of operating a source which is

subject to registration without a valid, current registration shall 

constitute a separate violation and subject the operator to a civil penalty 

not to exceed $100.00 per violation.

5-803 REGISTRATION PROCEDURE

(1) On or before February 1 of each year, the operator of each source 

subject to registration shall submit to the Air Pollution Control 

Officer source emissions data and any other information required to 

determine the appropriate registration fee. This data shall be supplied 

by completion of forms which are available from the Air Pollution 

Control Officer. The forms will not be deemed completed unless and 

until all information required by the forms has been supplied. The Air 

Pollution Control Officer may require such information to be submitted 

with respect to any source which he or she has reason to believe may be 

a source subject to registration. This subsection is not intended to 

limit any powers otherwise held by the Air Pollution Control Officer.

(2) The Air Pollution Control Officer shall determine the registration fee 

based upon the information required by the preceding subsection, upon 

other information reasonably required by him or her, and any other 

relevant information. Upon such determination, the Air Pollution 

Control Officer shall promptly notify each operator in writing of the 

registration fee required, if any.

(3) Any operator may request reconsideration of a fee determination within 

30 calendar days of receiving notice of such determination. Such 

request shall be in writing addressed to the Air Pollution Control 
VAPCR Adopted September 2011 [124]

Officer and shall include the operator's own calculation of the fee due 

along with all supporting documentation. Within 20 calendar days of 

receipt of such timely written request, the Air Pollution Control 

Officer shall notify the operator of the decision.

(4) Any operator who chooses to contest the decision of the Air Pollution 

Control Officer described in the preceding subsection may, within 15 

calendar days after receipt of such decision, request an administrative 

conference of the Commissioner of Environmental Conservation. Said 

conference shall be held as soon as reasonably possible, shall be 

informal in nature and shall serve as an opportunity for the operator 

to contest the decision of the Air Pollution Control Officer to the 

Commissioner by presenting emissions data and any other relevant 

information to the Commissioner or his or her representative. Such 

administrative conference shall not be considered a "contested case" as 

defined by 3 V.S.A. Ch. 25. The Commissioner shall notify the operator

of the decision within 30 days of the administrative conference. Should 

the Commissioner's decision be wholly or partially adverse to the 

operator, such notice shall include an explanation of the grounds for 

the decision. 

(5) Each operator from whom a registration fee is due shall pay said fee to 

the Air Pollution Control Officer on or before May 15 of each year. 

Payment shall be by check or money order made payable to the state of 

Vermont. If the amount of the fee is at that time the subject of an 

administrative appeal or judicial review, the fee amount most recently 

decided or determined by the Air Pollution Control Officer or 

Commissioner of Environmental Conservation is due. No registration will 

be issued for those sources for which a required registration fee has 

not been paid in full. If, however, at the conclusion of any and all 

administrative appeals and judicial review, the fee paid is greater 

than that which has been determined to be correct, the difference shall 

be promptly refunded to the operator.

(6) The period of each registration or renewal shall be from the first day 

of July of each year through the last day of June of the following 

calendar year.

5-804 FALSE OR MISLEADING INFORMATION

All data and other information submitted or caused to be submitted by an 

operator to the Agency shall be complete and truthful. Any such submission 

which is false or misleading shall be sufficient grounds for the denial or 

revocation of registration, and may result in a fine and/or imprisonment 

under the authority of the applicable Vermont statutes.

5-805 COMMENCEMENT OR RECOMMENCEMENT OF OPERATION

A source otherwise subject to registration is not required to register for 

the next period of registration unless it emitted more than five tons of air

(5) The Secretary will keep a record of the commenters and also of 

the issues raised during the public comment period and the public 

informational meeting, if conducted.

(b) For operating permit applications for all subject sources which are 

neither a Subchapter X major source nor Title V subject source and for 

applications for all administrative and minor permit amendments

pursuant to Section 5-1013(a) and (b) of this subchapter, opportunity 

for public participation may be provided at the discretion of the 

Secretary. In determining whether to provide for such public 

participation, the Secretary shall consider the degree of toxicity of 

the air contaminant and the emission rate, the proximity of the subject 

source to residences, population centers and other sensitive human 

receptors, and emission dispersion characteristics at or near the 

subject source. If the Secretary requires such an opportunity for 

public participation, it will be in such manner as determined in the 

discretion of the Secretary.

(c) Applications for operating permit renewal are subject to the same 

public participation requirements that apply to initial operating 

permit applications, except that a permit being renewed shall not be 

subject to the public notice and comment requirements of subsection (a) 

of this section if:

(1) The Secretary determines that no substantive changes have 

occurred at the subject source that would affect emissions or 

require changes to the permit;

(2) The Secretary determines no new statutory or regulatory 

requirements need to be added to the permit; and

(3) The subject source is not a Title V subject source.

(d) At his/her discretion, the Secretary may hold any public comment period 

or public informational meeting pursuant to this section jointly and 

concurrently with any public comment period or public informational 

meeting pursuant to Section 5-501 of the Air Pollution Control 

Regulations.

5-1008 SECRETARY'S POWERS AND DUTIES

(a) The Secretary may refuse to issue, renew, amend or modify an operating 

permit upon any of the following grounds:

(1) The owner/operator fails to submit pertinent and material 

information requested by the Secretary;

(2) There exists at the subject source unresolved noncompliance with 

applicable requirements or conditions of an existing permit 

issued under this Chapter and the owner/operator will not 

undertake a schedule of compliance that is acceptable to the 

Secretary to resolve the noncompliance;
VAPCR Adopted September 2011 [140]

(3) An owner/operator fails to fully disclose all facts relevant to 

the subject source, or knowingly submits false or misleading 

information to the Secretary; or,

(4) With respect to a subject source proposed to be permitted, the 

owner/operator has failed to pay a penalty or other sums owed 

pursuant to, or has otherwise failed to comply with, a court 

order, consent decree, stipulation agreement, schedule of 

compliance, or an order issued under Vermont statutes. 

(b) For Title V subject sources, the Secretary will forward the operating 

permit application, proposed operating permit, and the legal and 

factual basis for proposed operating permit conditions to EPA for 

review. Within the later of forty five (45) days of its receipt of the 

proposed operating permit or forty-five (45) days of its receipt of 

Vermont’s notice relating to nonacceptance of Affected State comments, 

EPA may object to the issuance of a final operating permit if it 

determines that the issuance of a final operating permit will not 

comply with the requirements of 40 C.F.R. Part 70. This subsection (b) 

shall not apply to applications for administrative operating permit 

amendments. 

(c) Within ninety (90) days of the date of an EPA objection to a proposed 

operating permit, the Secretary will respond in writing to the 

objection, revise the proposed operating permit if necessary, and 

either issue or deny a final operating permit in accordance with EPA’s 

objection. For Title V subject sources, the Secretary shall provide 

copies of issued operating permits, including amended operating 

permits, to EPA.

(d) The Secretary may issue an operating permit to a subject source which 

is not in compliance with applicable requirements. Such permit will 

include an appropriate schedule of compliance which is acceptable to 

the Secretary.

(e) (1) For Title V subject sources, the Secretary shall reopen an 

operating permit and, then, shall reissue, amend, suspend or 

terminate, as appropriate, the permit when: 

(i) There are additional applicable requirements with a 

remaining operating permit term of 3 or more years, and 

shall complete the reopening within eighteen months of the 

promulgation of the requirement;

(ii) There are additional applicable requirements for a Title IV 

affected source under the acid rain program;

(iii) The Secretary or EPA determines that the permit contains a 

material mistake or that inaccurate information was used to 

establish emissions standards or other terms or conditions 

of the permit; or

(iv) The Secretary or EPA determines such action is necessary to 

assure compliance with applicable requirements.
VAPCR Adopted September 2011 [141]

(2) For any subject source, the Secretary may reopen and, then, 

reissue, amend, suspend or terminate an operating permit for good 

cause. Good cause includes, but is not limited to, situations 

where:

(i) there are additional applicable requirements; 

(ii) the permit contains a material mistake or that inaccurate 

information was used to establish emissions standards or 

other terms or conditions of the permit; 

(iii) the subject source has failed to comply with a permit 

condition; or

(iv) the grounds for refusal to issue, renew or modify an 

operating permit under subsection (a) of this section 

exist.

(3) In the event the Secretary reopens a permit pursuant to paragraph 

(e)(1) or (e)(2) of this subsection, the procedures required for 

initial operating permit application and issuance or permit 

amendments shall apply, except that they shall apply only to 

those parts of the operating permit for which cause to reopen 

exists. Except in an emergency, the Secretary shall provide at 

least thirty (30) days notice to the owner/operator, of the 

Secretary’s intent to reopen. Such procedures need not be 

followed for suspension, termination, or revocation of a permit.

(f) The Secretary may issue a single permit authorizing emissions from 

similar operations by the same owner/operator at multiple temporary 

locations. The operations must be temporary and involve at least one 

change of location during the term of the permit. Such permits shall 

require at least ten (10) days notice to the Secretary prior to each 

change in location.

(g) The Secretary shall implement the requirements and provisions of Title 

IV of the federal Clean Air Act [42 U.S.C. 7651-7651o] and the 

regulations promulgated thereunder. If any provisions or requirements 

of Title IV of the federal Clean Air Act and the regulations 

promulgated thereunder conflict with or are not included in this 

Subchapter, the requirements and provisions of Title IV of the federal 

Clean Air Act shall apply and take precedence. 

5-1009 ACTION ON OPERATING PERMIT APPLICATIONS

applicable requirements and the requirements of this subchapter.

(b) The Secretary will take final action on each operating permit 

application within eighteen (18) months after receiving an 

administratively complete application.

5-1010 REASONABLY AVAILABLE CONTROL TECHNOLOGY (RACT)

(a) The owner/operator of a Subchapter X major source shall install, 

maintain, and use reasonably available control technology (RACT) to 

limit the discharge of air contaminants from each process unit and each 

fuel burning equipment unit at such subject source, if and as required 

by the conditions of an operating permit.

(b) Except as provided in subsection (c) of this section, any RACT

requirement pursuant to subsection (a) of this section shall be 

determined by the Secretary for each subject source or category of 

subject sources after consideration of all available pertinent 

information. Before final action is taken on an operating permit

application, the Secretary may require the owner/operator of a 

stationary source subject to this section to submit information to the 

Secretary to establish whether RACT will be achieved.

(c) Any RACT requirement for VOCs pursuant to Section 5-253 of this Chapter 

or nitrogen oxides pursuant to Section 5-251(3), or any most stringent 

emission rate (MSER) requirement to which a stationary source is 

otherwise subject for a process unit and/or fuel burning equipment unit 

at the time of application for an operating permit, shall be the 

applicable RACT requirement pursuant to subsection (a) of this section 

for such process unit and/or fuel burning equipment unit provided that 

such MSER or RACT requirement was established less than ten (10) years 

prior to the operating permit application being determined or deemed 

administratively complete.

5-1011 TERM OF OPERATING PERMIT

Each operating permit issued under this subchapter shall be for a fixed term 

determined by the Secretary, not to exceed five (5) years.

5-1012 PERMIT EXPIRATION AND RENEWAL

(a) Each operating permit, unless sooner terminated in accordance with 

Section 5-1008(e), will expire at the end of its term except as

requirements, including those for public participation, that apply to 

initial operating permit applications, except as provided under Section 

5-1007(c) of this subchapter.
VAPCR Adopted September 2011 [143]

(c) If a timely and administratively complete application for operating 

permit renewal is submitted to the Secretary, but the Secretary has 

failed to issue or deny such renewal before the end of the term of the 

previous permit, then the owner/operator may continue to operate the 

subject source and all terms and conditions of such previous operating 

permit shall remain in effect until the Secretary has issued or denied 

the operating permit renewal. However, such previous operating permit

shall automatically expire if, subsequent to the application being 

determined or deemed administratively complete pursuant to Section 5-

1006 of this subchapter, the owner/operator fails to submit any 

additional information required by the Secretary as well as information 

pertaining to changes to the subject source within thirty (30) days or 

such other period specified in writing by the Secretary.

5-1013 OPERATING PERMIT AMENDMENTS 

(a) An administrative operating permit amendment may be made by the 

Secretary consistent with the following:

(1) The Secretary may incorporate such changes without providing 

notice to the public or affected States. 

(2) The owner/operator may implement the changes addressed in the 

request for an administrative operating permit amendment

immediately upon submittal of the request to the Secretary. 

Notwithstanding Section 5-1009(b) of this subchapter, the 

Secretary will act on the request within 60 days of its receipt 

by the Secretary. Should the Secretary deny the request, the 

owner/operator must take whatever action is necessary to comply 

with the denial.

(b) The Secretary may issue a minor permit amendment without providing 

opportunity for public participation (Section 5-1007) provided the 

applicant submits an administratively complete application which 

includes: 

(1) a description of the proposed change, the emissions which would 

result from the proposed change, and any new requirements that 

will apply if the change occurs;

(2) citation of all requirements applicable to the subject source as 

a result of the change and a description of how compliance with 

such requirements can be determined;

(3) certification by a responsible official that the proposed change 

is eligible to be processed as a minor permit amendment in 

accordance with Section 5-1002 of this subchapter.

(c) Except as provided in (a) and (b) above, the procedure for processing 

an application for an operating permit amendment shall be the same as 

that used to process an application for an initial operating permit. In 

the case of a minor permit amendment for a Title V subject source, the 

Secretary shall notify affected states and EPA upon receipt of an 
VAPCR Adopted September 2011 [144]

administratively complete application and the proposed permit shall be 

subject to Section 5-1008(b) and (c) of this subchapter.

(d) An operating permit amendment for the purposes of the acid rain portion 

of an operating permit shall be subject to regulations promulgated 

under Title IV of the federal Clean Air Act [42 U.S.C. 7651-7651o].

5-1014 OPERATIONAL FLEXIBILITY

(a) An owner/operator may make a change to a permitted subject source

without securing approval of the Secretary or requesting an operating 

permit amendment provided that: 

(1) The change does not constitute a modification under any provision 

of the Air Pollution Control Regulations;

(2) The change is not subject to Title IV of the federal Clean Air 

Act [42 U.S.C. 7651-7651o];

(3) The change does not cause any subject source to exceed the 

emissions allowable under the operating permit (whether expressed 

therein as a rate of emissions or in terms of total emissions);

(4) The change meets all applicable requirements and the change does 

not contravene a permit term and condition for monitoring, record 

keeping, reporting, or compliance certification;

(5) For the balancing of emissions increases and decreases between 

emission units at a Title V subject source, all emissions from 

the change are quantifiable and there are replicable procedures 

to enforce the emission trades; and, 

(6) The owner/operator of the permitted subject source provides the 

Secretary (and the EPA for Title V subject sources) with written 

notice received at least fifteen (15) days in advance of the 

proposed change. Such notice shall include a brief description of 

the change within the permitted facility, the date on which the 

change will occur, any change in emissions, and any permit term 

that is no longer applicable as a result of the change. The 

owner/operator shall attach a copy of such written notice to the 

operating permit.

5-1015 PERMIT CONTENT

(a) Each operating permit issued to a Title V subject source under this 

subchapter will include the following elements:

(1) Specified emission limitations and standards, including those 

operational requirements and limitations that assure compliance 

with all applicable requirements;

(2) A reference, but not necessarily all references, of the origin 

and authority for each term or condition; 
VAPCR Adopted September 2011 [145]

(3) Emission monitoring and analysis procedures or test methods 

required under the applicable requirements;

(4) Conditions for record keeping and periodic monitoring as the 

Secretary deems necessary to collect reliable data representative

reports of any required monitoring, certified by a responsible 

official in accordance with Section 5-1006(f) of this subchapter, 

at least every six (6) months;

(6) Prompt reporting of deviations from permit requirements, 

including those attributable to upset conditions as defined in 

the permit, the probable cause of such deviations, and any 

corrective actions or preventative measures taken. Prompt shall 

be defined on a case-by-case basis in each operating permit, 

shall be at least as stringent as is required for permits issued 

to Title V subject sources by EPA, and shall be determined in 

relation to the degree and type of deviation likely to occur and 

the applicable requirements;

(7) A provision requiring that reports, records of all monitoring 

data and related information required by the operating permit be 

retained by the subject source for at least five (5) years from 

the date of the monitoring, measurement, or report; 

(8) Terms and conditions, including the requirement to maintain 

records of switches in operating scenario, for reasonably 

anticipated alternative operating scenarios identified by the 

subject source in its application as approved by the Secretary;

requirements;

(11) Requirements for submittal of compliance certifications, 

including, but not limited to, the frequency of submission of 

compliance certifications;

(12) If necessary, a schedule of compliance and requirements for 

submittal of progress reports;
VAPCR Adopted September 2011 [146]

(13) Provisions indicating that the Secretary may reopen an operating 

permit prior to the expiration of the operating permit in 

accordance with Section 5-1008(e); and,

(14) If requested by an owner/operator in accordance with the 

provisions of this subsection, a "permit shield" provision that 

identifies specific state or federally enforceable regulations 

and standards derived therefrom which are not applicable to a 

source. Enforcement actions based on those identified regulations 

and standards may not be initiated against the source covered by 

the shield. However, a Apermit shield@ is not available as part 

of an administrative or minor permit amendment and does not apply 

to changes permitted under Section 5-1014.

(i) Such a shield shall only have legal effect if:

(A) The Secretary, in acting on an operating permit 

application, determines in writing which specific 

state or federally enforceable regulations and 

standards derived therefrom are not applicable to the 

stationary source and the operating permit contains 

an express delineation of each such regulation or 

standard;

(B) The applicant includes, in its application, a draft 

permit shield provision in the form and with the 

elements specified by the Secretary, itemizing each 

specific state or federally enforceable regulation or 

standard derived therefrom which said applicant 

believes is not applicable to such stationary source; 

and,

(C) An operating permit expressly states that a "permit 

shield" exists in accordance with this subsection, 

otherwise the operating permit shall not provide such 

a shield;

(ii) A permit shield shall not limit the Secretary's ability to 

reopen and/or amend an operating permit pursuant to Section 

5-1008(e) of this subchapter. Notwithstanding any other 

provision of this subchapter, the Secretary need not 

receive an operating permit application from the 

owner/operator of a subject source in order to reopen 

and/or amend a "permit shield" provision.

(iii) Notwithstanding paragraph (14) of this subsection, the 

stationary source must comply with those state or federally 

enforceable regulations and standards that become 

applicable during the term of the operating permit, even if 

those requirements are not set forth in the operating 

permit.

(iv) Notwithstanding this paragraph (14) of this subsection, an 

owner/operator shall remain liable for any violation of 
VAPCR Adopted September 2011 [147]

applicable provisions of law that occurred prior to or at 

the time of issuance of an operating permit.

(v) The permit shield shall be void if it is based on or 

affected by any false, inaccurate, or incomplete 

information provided by the applicant.

(vi) The permit shield shall not limit in any way or prevent the 

Secretary from issuing an emergency administrative order in 

accordance with 10 V.S.A. §8009 or an emergency order 

pursuant to 10 V.S.A. §560. The permit shield shall remain 

in effect with respect to any regulations or standards 

delineated in the permit shield provision which are not 

affected by, or the basis for such emergency orders. No 

emergency administrative order issued to an owner/operator

which is based on regulations or standards that are 

delineated in such source's permit shield provision shall 

contain monetary penalties.

(vii) The permit shield shall not apply to, or affect those 

provisions of law which implement the requirements and 

provisions of Title IV of the federal Clean Air Act (42 

U.S.C. 7651-7651o) and the regulations promulgated 

thereunder.

(15) If requested by the owner/operator, terms and conditions for the 

balancing of emissions increases and decreases between emission 

units at a Title V subject source for the purpose of complying 

with a federally enforceable emissions cap contained in the 

operating permit if such balancing of emissions is permissible 

under Section 5-1014;

(16) Such other provisions, consistent with this subchapter, 10 V.S.A. 

Chapter 23, the federal Clean Air Act [42 U.S.C. 7401, et seq.] 

and the regulations promulgated thereunder, as the Secretary may 

incorporate.

(b) For subject sources other than Title V subject sources, each operating 

permit may include any or all of the elements set forth in subsection 

(a), above.

5-1016 LIMITING ALLOWABLE EMISSIONS

(a) For any air contaminant source that is not a Title V subject source and 

which is subject to this subchapter solely due to Section 5-1003(a)(1), 

if the owner/operator demonstrates to the satisfaction of the Secretary

that actual emissions of air contaminants from the stationary source

have not equaled or exceeded ten (10) tons in any calendar year 

commencing January 1, 1995, then the actual emissions of such 

stationary source for such calendar year shall be deemed to be the 

stationary source’s allowable emissions, notwithstanding Section 5-101

of these regulations. Such stationary source need not secure an 

operating permit which would otherwise be required by this subchapter 

so long as actual emissions of air contaminants from the stationary 

source are less than ten (10) tons per calendar year.
VAPCR Adopted September 2011 [148]

(b) In order to make such a demonstration to the Secretary, the 

owner/operator must submit an annual registration to the Secretary, in 

accordance with the procedures specified in Subchapter VIII of these 

regulations, certifying that actual emissions of air contaminants from 

the stationary source, for the preceding year, did not exceed ten (10) 

tons.

(c) No air contaminant source, which is exempt under this section from the 

operating permit requirement, shall emit ten (10) tons or more of air 

contaminants in a calendar year or violate any provision of this 

section. 

(d) The owner/operator of an air contaminant source making an annual 

certification under this section shall keep and maintain records to 

determine actual emissions. Such records shall include, but not be 

limited to, emissions monitoring, monitoring of fuel usage, production 

rates, hours of operation, product purchases, and any other information 

that the Secretary may require to calculate actual emissions from the 

air contaminant source. Such information shall be summarized in a 

monthly log, maintained on-site for a minimum of five (5) years from 

the date of record, and shall be made available to the Secretary upon 

request. Additionally, such owner/operator shall consent, in writing, 

to provide authorized representatives of the Secretary with access, at 

reasonable times, to all properties where emissions related activity is 

conducted for the purpose of verifying the accuracy of such annual 

certification.

APPENDIX D

METHOD FOR THE DERIVATION OF HAZARDOUS AMBIENT AIR STANDARD

This appendix presents the standard procedure which shall be used by the 

Secretary when deriving a Hazardous Ambient Air Standard (HAAS), in 

micrograms per cubic meter, for a hazardous air contaminant. In the event the 

United States Environmental Protection Agency (U.S. EPA) adopts an ambient 

air quality standard or a standardized method for determining such a standard 

for a hazardous air contaminant, the Secretary may set the HAAS for the 

contaminant at the level or by the method so established by the U.S. EPA. The 

HAAS may be no less stringent than the Federal ambient air quality standard.

CATEGORY I: Hazardous Air Contaminants that are Known or Suspected 

Carcinogens

Hazardous air contaminants that have been listed as potentially carcinogenic 

by the U.S. EPA, or International Agency for Research on Cancer, shall be 

classified as Category I: known or suspected carcinogens (except for HACs 

solely categorized by IARC as Group 1, inhaled in a form from occupational 

sources). Hazardous air contaminants that are reported to induce cancer in 

two or more species by the National Toxicological Program may also be 

classified as known or suspected carcinogens by the Secretary after 

consultation with the Vermont Department of Health. 

The HAAS for each Category 1 hazardous air contaminant shall be set at a 

level estimated to correspond to an excess lifetime carcinogenic risk of one 

in one million assuming continual inhalation exposure. In cases where there 

is insufficient data available to derive such a value, the HAAS shall be set 

at 0.01 μg/m3.

The averaging period for known or suspected carcinogens shall be annual. 

CATEGORIES II AND III: Hazardous Air Contaminants Believed to Cause Chronic 

Systemic Toxicity due to Long-term Exposure or Shortterm Irritant Effects

Those hazardous air contaminants not identified as potentially carcinogenic 

as defined above, are referred to as noncarcinogens and are divided into two 

categories: 

Category II: Hazardous Air Contaminants Believed to Cause Chronic 

Systemic Toxicity due to Long-term Exposure; and 

Category III: Hazardous Air Contaminants Believed to Cause Short-term 

Irritant Effects. 

For both types of effects, it is generally assumed that some threshold level 

of toxicity exists (i.e. there is some level of exposure below which no 

adverse health effects are likely to occur).

Because the actual threshold level of exposure will vary from individual to 

individual, assessment of such compounds focuses on estimating a population 

threshold level. The HAAS for each Category II and Category III compound 

shall be set at a level estimated to correspond to such a threshold based on 

continual inhalation exposure. 
VAPCR Adopted September 2011 [180]

Various sources of toxicity information shall be examined in the development 

of a HAAS for each Category II and Category III hazardous air contaminants. 

These sources shall include, but are not limited to: U.S. EPA RfCs, 

occupational values (e.g., ACGIH TLVs, NIOSH RELS, VOSHA PELs), ATSDR MRLs, 

California EPA RELs, National AEGLs and reports published in the peer 

reviewed literature.

Uncertainty Factor

One or more uncertainty factors, each ranging from 1 to 10, may be applied in 

the development of a HAAS for each Category II or Category III hazardous air 

contaminant. Where appropriate, an additional modifying factor, typically 

ranging from 1 to 10, may be included in the calculation. The total 

adjustment factor applied will depend on the nature and extent of chemical 

specific toxicity information available for review.

Averaging Time

The averaging period for Category II hazardous air contaminants shall be 

annual. A 24 hour averaging period will be employed for Category III

hazardous air contaminants.

Alternative Methods

In the event that insufficient toxicological information is available with 

which to derive a HAAS for Category II and Category III hazardous air 

contaminants, a default value shall be set for each category at the median

value of all HAAS published in Appendix C for the given category. The action 

level shall be derived in accordance with Appendix E. 

a. The Category II median HAAS is 20 μg/m3 and its representative 

action level is 1.7 lbs/8 h. 

b. The Category III median HAAS is 36 μg/m3 and its representative 

action level is 1.9 lbs/8 h.
VAPCR Adopted September 2011 [181]

APPENDIX E

METHOD FOR THE DERIVATION OF ACTION LEVELS

This appendix presents the standard procedure which shall be used by the 

Secretary when deriving an Action Level, in pounds of emissions per eight 

hours, for a hazardous air contaminant.

Action Levels shall be calculated for all hazardous air contaminants for 

which the Secretary has established a HAAS by one of the following methods:

1. For hazardous air contaminants with a HAAS based on a twenty-four hour 

averaging period, the HAAS shall be multiplied by 0.052.

2. For hazardous air contaminants with a HAAS based on an annual averaging 

period, the HAAS shall be multiplied by 0.083.
