QUALITY BOARD

[ 25 PA CODE CH. 129 ]

Control of Volatile Organic Compound Emissions

from Fiberglass Boat Manufacturing Materials

The Environmental Quality Board (Board) proposes to

amend Chapter 129 (relating to standards for sources) to

read as set forth in Annex A. The proposed rulemaking

would add § 129.74 (relating to control of VOC emissions

from fiberglass boat manufacturing materials) to adopt

reasonably available control technology (RACT) requirements and RACT emission limitations for stationary

sources of volatile organic compound (VOC) emissions

from fiberglass boat manufacturing materials including

open molding resins, gel coats and cleaning materials.

The proposed rulemaking would also add terms and

definitions to § 129.74 to support the interpretation of

the proposed measures.

This proposed rulemaking will be submitted to the

United States Environmental Protection Agency (EPA) for

approval as a revision to the Commonwealth’s State

Implementation Plan (SIP) following promulgation of the

final-form regulation.

This proposed rulemaking is given under Board order

at its meeting of May 21, 2014.

A. Effective Date

This proposed rulemaking will be effective upon finalform publication in the Pennsylvania Bulletin.

on the Department of Environmental Protection’s (Department) web site at www.dep.state.pa.us (select ‘‘Public

Participation Center,’’ then select ‘‘Environmental Quality

Board’’).

C. Statutory Authority

The proposed rulemaking is authorized under section

5(a)(1) of the Air Pollution Control Act (APCA) (35 P. S.

§ 4005(a)(1)), which grants the Board the authority to

adopt rules and regulations for the prevention, control,

reduction and abatement of air pollution in this Commonwealth. Section 5(a)(8) of the APCA also grants the Board

the authority to adopt rules and regulations designed to

implement the provisions of the Clean Air Act (CAA) (42

U.S.C.A. §§ 7401—7671q).

D. Background and Purpose

The purpose of this proposed rulemaking is to implement control measures to reduce VOC emissions from

fiberglass boat manufacturing materials including open

molding resin, gel coat and cleaning materials. VOCs are

precursors for ground-level ozone formation. Ground-level

ozone, a public health and welfare hazard, is not emitted

directly to the atmosphere by fiberglass boat manufacturing materials including open molding resin, gel coat and

cleaning materials, but is formed by a photochemical

reaction between VOCs and nitrogen oxides (NOx) in the

presence of sunlight. In accordance with sections

172(c)(1), 182(b)(2)(A) and 184(b)(1)(B) of the CAA (42

U.S.C.A. §§ 7502(c)(1), 7511a(b)(2)(A) and 7511c(b)(1)(B)),

the proposed rulemaking establishes the VOC emission

limitations and other requirements of the EPA 2008

Fiberglass Boat Manufacturing Materials Control Techniques Guidelines (CTG) for these sources in this Commonwealth. See Consumer and Commercial Products,

Group IV: Control Techniques Guidelines in Lieu of

Regulations for Miscellaneous Metal Products Coatings,

Plastic Parts Coatings, Auto and Light-Duty Truck Assembly Coatings, Fiberglass Boat Manufacturing Materials, and Miscellaneous Industrial Adhesives, 73 FR

58481, 58483 (October 7, 2008).

The EPA is responsible for establishing National Ambient Air Quality Standards (NAAQS) for six criteria

pollutants considered harmful to public health and the

environment: ground-level ozone; particulate matter; NOx;

carbon monoxide; sulfur dioxide; and lead. The CAA

established two types of NAAQS: primary standards,

which are limits set to protect public health; and secondary standards, which are limits set to protect public

welfare and the environment, including protection against

visibility impairment and from damage to animals, crops,

vegetation and buildings. The EPA established primary

and secondary ground-level ozone NAAQS to protect

public health and welfare.

Ground-level ozone is a highly reactive gas, which at

sufficiently high concentrations can produce a wide variety of harmful effects. At elevated concentrations, groundlevel ozone can adversely affect human health, animal

health, vegetation, materials, economic values, and personal comfort and well-being. It can cause damage to

important food crops, forests, livestock and wildlife. Repeated exposure to ozone pollution may cause a variety of

adverse health effects for both healthy people and those

with existing conditions, including difficulty in breathing,

chest pains, coughing, nausea, throat irritation and congestion. It can worsen bronchitis, heart disease, emphysema and asthma, and reduce lung capacity. Asthma is a

significant and growing threat to children and adults.

High levels of ground-level ozone affect animals in ways

similar to humans. High levels of ground-level ozone can

also cause damage to buildings and synthetic fibers,

including nylon, and reduced visibility on roadways and

in natural areas. The implementation of additional measures to address ozone air quality nonattainment in this

Commonwealth is necessary to protect the public health

and welfare, animal and plant health, and welfare and

the environment.

In July 1997, the EPA promulgated primary and secondary ozone standards at a level of 0.08 part per million

(ppm) averaged over 8 hours. See 62 FR 38856 (July 18,

1997). In 2004, the EPA designated 37 counties in this

Commonwealth as 8-hour ozone nonattainment areas for

the 1997 8-hour ozone NAAQS. Based on the ambient air

monitoring data for the 2013 ozone season, all monitored

areas of this Commonwealth are attaining the 1997

8-hour ozone NAAQS. The Department must ensure that

the 1997 ozone standard is attained and maintained by

implementing permanent and enforceable control measures to ensure violations of the standard do not occur for

the next decade.

In March 2008, the EPA lowered the standard to 0.075

ppm averaged over 8 hours to provide even greater

protection for children, other at-risk populations and the

environment against the array of ozone-induced adverse

health and welfare effects. See 73 FR 16436 (March 27,

2008). In April 2012, the EPA designated five areas in

this Commonwealth as nonattainment for the 2008 ozone

NAAQS. See 77 FR 30088, 30143 (May 21, 2012). These

areas include all or a portion of Allegheny, Armstrong,

Berks, Beaver, Bucks, Butler, Carbon, Chester, Delaware,

Fayette, Lancaster, Lehigh, Montgomery, Northampton,

Philadelphia, Washington and Westmoreland Counties.

The Commonwealth must ensure that these areas attain

the 2008 ozone standard by 2015 and that they continue

to maintain the standard thereafter.

There are not Federal statutory or regulatory RACT

limits for VOC emissions from fiberglass boat manufacturing materials. In 2001, however, the EPA promulgated

40 CFR Part 63, Subpart VVVV (relating to National

emission standards for hazardous air pollutants for boat

manufacturing) (2001 NESHAP). The 2001 NESHAP

established organic hazardous air pollutant (HAP) emissions limits based on low-HAP resins and gel coats and

low-emitting resin application technology. Many HAPs are

VOCs, but not all VOCs are HAPs. The 2001 NESHAP

data, however, indicate that styrene and methyl

methacrylate, which are both organic HAP and VOC,

account for nearly all the VOC emissions, as well as HAP

emissions, from fiberglass boat manufacturing facilities.

Therefore, total HAP and VOC emissions from fiberglass

boat manufacturing facilities are nearly equal.

When developing the VOC emission reduction RACT

measures included in its Fiberglass Boat Manufacturing

Materials CTG, the EPA took into account the HAP

emission reduction measures of the 2001 NESHAP for the

boat manufacturing industry. The requirements of the

2001 NESHAP apply to ‘‘major sources’’ of HAP from boat

manufacturing operations. For the purpose of regulating

HAPs, a ‘‘major source’’ is considered to be a stationary

PROPOSED RULEMAKING 4503

PENNSYLVANIA BULLETIN, VOL. 44, NO. 29, JULY 19, 2014
source or group of stationary sources located within a

contiguous area and under common control that emits or

has the potential to emit considering controls, in the

aggregate, 10 tons per year (tpy) or more of any single

listed HAP or 25 tpy or more of any combination of HAPs.

See section 112(a)(1) of the CAA (42 U.S.C.A.

§ 7412(a)(1)). See 66 FR 44218, 44219 (August 22, 2001).

State regulations to control VOC emissions from fiberglass boat manufacturing materials are required under

Federal law and will be reviewed and approved by the

EPA if the provisions meet the RACT requirements of the

CAA and its implementing regulations. See 73 FR 58481,

58483. The EPA defines RACT as ‘‘the lowest emission

limitation that a particular source is capable of meeting

by the application of control technology that is reasonably

available considering technological and economic feasibility.’’ See State Implementation Plans; General Preamble

for Proposed Rulemaking on Approval of Plan Revisions

for Nonattainment Areas—Supplement (on Control Techniques Guidelines), 44 FR 53761 (September 17, 1979).

Section 172(c)(1) of the CAA provides that SIPs for

nonattainment areas must include ‘‘reasonably available

control measures,’’ including RACT, for sources of emissions. Section 182(b)(2) of the CAA provides that for

moderate ozone nonattainment areas, states must revise

their SIPs to include RACT for sources of VOC emissions

covered by a CTG document issued by the EPA prior to

the area’s date of attainment. More importantly, section

184(b)(1)(B) of the CAA requires that states in the Ozone

Transport Region (OTR), including the Commonwealth,

submit an SIP revision requiring implementation of

RACT for all sources of VOC emissions in the state

covered by a specific CTG.

Section 183(e) of the CAA (42 U.S.C.A. § 7511b(e))

directs the EPA to list for regulation those categories of

products that account for at least 80% of the VOC

emissions from consumer and commercial products in

ozone nonattainment areas. Section 183(e)(3)(C) of the

CAA further provides that the EPA may issue a CTG

document in place of a National regulation for a product

category when the EPA determines that the CTG will be

‘‘substantially as effective as regulations’’ in reducing

emissions of VOC in ozone nonattainment areas. In 1995,

the EPA listed fiberglass boat manufacturing on its

section 183(e) list and, in 2008, the EPA issued a CTG for

this product category. See 60 FR 15264, 15267 (March 23,

1995) and 73 FR 58481. See Control Techniques Guidelines for Fiberglass Boat Manufacturing Materials, EPA

453/R-08-004, Office of Air Quality Planning and Standards, EPA, September 2008. The Fiberglass Boat Manufacturing Materials CTG is available on the EPA web site

at www.epa.gov/airquality/ozonepollution/SIPToolkit/

ctgs.html.

In the 2008 notice of final determination and availability of final CTGs, the EPA determined that the recommendations of the Fiberglass Boat Manufacturing Materials CTG would be substantially as effective as National

regulations in reducing VOC emissions from the fiberglass boat manufacturing materials product category in

ozone nonattainment areas. See 73 FR 58481. The CTG

provides states with the EPA’s recommendation of what

constitutes RACT for the covered category. States can use

the Federal recommendations provided in the CTG to

inform their own determination as to what constitutes

RACT for VOC emissions from the covered category. State

air pollution control agencies may implement other

technically-sound approaches that are consistent with the

CAA requirements and the EPA’s implementing regulations or guidelines.

The Department reviewed the recommendations included in the 2008 Fiberglass Boat Manufacturing Materials CTG for their applicability to the ground-level ozone

reduction measures necessary for this Commonwealth.

The Bureau of Air Quality determined that the measures

provided in the Fiberglass Boat Manufacturing Materials

CTG are appropriate to be implemented in this Commonwealth as RACT for this category.

This proposed rulemaking would affect the owner and

operator of one known Title V major facility in this

Commonwealth. The Board anticipates that the affected

owner of the facility would demonstrate compliance with

the proposed measures to reduce VOC emissions because

this facility is already subject to the 2001 NESHAP HAP

emission control requirements. These NESHAP provisions

are applicable requirements in the Federally-enforceable

Title V permit issued by the Department to the owner

and operator on January 23, 2008. It is possible that the

proposed rulemaking would also affect owners and operators of other fiberglass boat manufacturing facilities that

have not yet been identified, because the 2001 NESHAP

does not apply to area sources (that is, sources that emit

less than 10 tpy of any single listed HAP or less than 25

tpy of any combination of HAPs). Owners and operators

of area source fiberglass boat manufacturing facilities are,

therefore, not currently required to implement the HAPreduction measures provided in the 2001 NESHAP, which

are also included in the 2008 Fiberglass Boat Manufacturing Materials CTG as measures for reducing emissions

of VOCs from sources that meet the applicability threshold recommended by the EPA in the CTG.

The ground-level ozone reduction measures included in

this proposed rulemaking would achieve VOC emission

reductions locally and would also reduce the transport of

VOC emissions and ground-level ozone to downwind

states, if implemented for potentially unidentified existing

sources of VOC emissions from fiberglass boat manufacturing operations including open molding resin and gel

coat materials that are not currently controlled in this

Commonwealth. Adoption of VOC emission requirements

for fiberglass boat manufacturing materials is part of the

Commonwealth’s strategy, in concert with other OTR

jurisdictions, to further reduce transport of VOC ozone

precursors and ground-level ozone throughout the OTR to

attain and maintain the 8-hour ozone NAAQS.

The proposed rulemaking is required under the CAA

and is reasonably necessary to attain and maintain the

health-based and welfare-based 8-hour ozone NAAQS and

to satisfy related CAA requirements in this Commonwealth. If published as a final-form regulation in the

Pennsylvania Bulletin, this proposed rulemaking will be

submitted to the EPA as a revision to the Commonwealth’s SIP.

The proposed rulemaking was discussed with the Air

Quality Technical Advisory Committee (AQTAC) on December 12, 2013. The AQTAC voted unanimously to

concur with the Department’s recommendation to forward

the proposed rulemaking to the Board for consideration.

The proposed rulemaking was discussed with the Small

Business Compliance Advisory Committee (SBCAC) on

April 23, 2014. The SBCAC also voted unanimously to

forward the proposed rulemaking to the Board for consideration. The proposed rulemaking was discussed with the

Citizens Advisory Council (CAC) Policy and Regulatory

Oversight (PRO) Committee on March 12, 2014. On the

recommendation of the PRO Committee, on March 18,

2014, the CAC concurred with the Department’s recommendation to forward the proposed rulemaking to the

Board.

4504 PROPOSED RULEMAKING

PENNSYLVANIA BULLETIN, VOL. 44, NO. 29, JULY 19, 2014
E. Summary of Regulatory Requirements

§ 129.74. Control of VOC emissions from fiberglass boat

manufacturing materials

Under proposed subsection (a), the proposed rulemaking would apply Statewide to the owner and operator

of a facility that manufactures a hull or a deck of a boat

or a related part from fiberglass, builds a mold or plug to

make a fiberglass boat hull or deck or related part, or

makes polyester resin putties for assembling fiberglass

boat parts when the total actual VOC emissions from

fiberglass boat manufacturing operations identified in

Table I are equal to or greater than 15 pounds (6.8

kilograms) per day or 2.7 tons per 12-month rolling

period, before consideration of controls. The total actual

VOC emissions include the actual VOC emissions from

the manufacture of hulls or decks from fiberglass, fiberglass boat parts (including small parts such as hatches,

seats and lockers), molds or plugs for fiberglass hulls,

decks or boat parts, resin and gel coat mixing operations,

resin and gel coat application equipment and related

cleaning activities at the facility. As with all RACT

regulations, an owner or operator remains subject to the

regulation even if the throughput or VOC emissions fall

below the applicability threshold.

Proposed subsection (a) also specifies that the proposed

rulemaking would not apply to the owner and operator of

a facility that manufactures boat trailers or parts of

boats, such as hatches, seats and lockers, but does not

manufacture hulls or decks of boats from fiberglass or

build molds to make fiberglass boat hulls or decks.

Further, proposed subsection (a) establishes monomer

VOC content limits for open molding resin and gel coat

materials.

Under proposed subsection (b), the proposed rulemaking establishes 39 definitions to support the proposed

rulemaking.

Under proposed subsection (c), exceptions are established for certain operating circumstances.

Under proposed subsection (d), the requirements of this

proposed rulemaking supersede the requirements of a

RACT permit issued to an owner and operator of a source

subject to this section, except to the extent the RACT

permit contains more stringent requirements.

Under proposed subsection (e), the owner and operator

of a facility subject to this section shall comply with the

applicable requirements on the effective date of adoption

of this proposed rulemaking.

Under proposed subsection (f), the owner and operator

of a facility subject to this section may not cause or

permit the emission into the outdoor atmosphere of

monomer VOCs from an open molding resin or gel coat

fiberglass boat manufacturing operation, a resin or gel

coat mixing operation, or a resin or gel coat application

equipment cleaning operation unless one or more of the

specified limitations is met. Three options for meeting the

emission limits are proposed: use of compliant materials

as listed in Table I; monomer VOC emissions averaging;

or installation of a VOC emissions capture system and

add-on air pollution control device.

Under proposed subsection (g), the owner and operator

of a facility subject to this section opting to install a VOC

emissions capture system and add-on air pollution control

device must obtain a plan approval prior to installation

and operation of the VOC emissions capture system and

add-on air pollution control device.

Under proposed subsection (h), the owner and operator

of a facility subject to this section may use an adjusted

monomer VOC emission rate for filled production resins

and filled tooling resins in each of the options specified in

subsection (f).

Under proposed subsection (i), the monomer VOC content of an open molding resin, gel coat, filled production

resin or filled tooling resin material not included in an

emissions averaging option in subsection (f)(2) must meet

the monomer VOC content requirements of subsection

(f)(1) or the add-on air pollution control requirements of

subsection (f)(3).

Under proposed subsection (j), alternative requirements

for control of monomer VOC content for certain resin and

gel coat materials are established.

Under proposed subsection (k), work practices for resin

and gel coat materials are established.

Under proposed subsection (l), VOC content limits and

work practices for cleaning materials are established.

Under proposed subsection (m), compliance and monitoring requirements are established.

Under proposed subsection (n), sampling and testing

standards are established.

Under proposed subsection (o), recordkeeping requirements are established.

Under proposed subsection (p), reporting requirements

are established.

F. Benefits, Costs and Compliance

Benefits

Implementation of the VOC emission control measures

in the proposed rulemaking would benefit the health and

welfare of the approximately 12 million residents and the

numerous animals, crops, vegetation and natural areas of

this Commonwealth by reducing emissions of VOCs,

which are precursors to the formation of ground-level

ozone air pollution. Exposure to high concentrations of

ground-level ozone is a serious human and animal health

and welfare threat, causing respiratory illnesses and

decreased lung function, agricultural crop loss, visible

foliar injury to sensitive plant species, and damage to

forests, ecosystems and infrastructure. Reduced ambient

concentrations of ground-level ozone would reduce the

incidences of hospital admissions for respiratory ailments

including asthma and improve the quality of life for

citizens overall. While children, the elderly and those

with respiratory problems are most at risk, even healthy

individuals may experience increased respiratory ailments and other symptoms when they are exposed to

high levels of ambient ground-level ozone while engaged

in activities that involve physical exertion.

This proposed rulemaking is designed to adopt the

standards and recommendations in the EPA’s 2008 Fiberglass Boat Manufacturing Materials CTG to meet the

requirements of sections 172(c)(1), 182(b)(2) and

184(b)(1)(B) of the CAA. The proposed rulemaking would

apply the standards and recommendations in the CTG

across this Commonwealth, as required under section

184(b)(1)(B) of the CAA.

The Statewide implementation of the proposed rulemaking control measures would assist the Department in

reducing VOC emissions from fiberglass boat manufacturing operations locally, and reducing the resultant local

formation of ground-level ozone and transport of VOC

emissions and ground-level ozone to downwind states.

Statewide implementation would also facilitate implementation and enforcement of the proposed rulemaking in

this Commonwealth. The measures in the proposed rulemaking are reasonably necessary to attain and maintain

PROPOSED RULEMAKING 4505

PENNSYLVANIA BULLETIN, VOL. 44, NO. 29, JULY 19, 2014
the health-based and welfare-based 8-hour ozone NAAQS

and to satisfy related CAA requirements in this Commonwealth.

The proposed rulemaking may create economic opportunities for VOC emission control technology innovators,

manufacturers and distributors through an increased

demand for new or improved equipment. In addition, the

owners and operators of regulated facilities may be

required to install and operate an emissions monitoring

system or equipment necessary for an emissions monitoring method to comply with the proposed rulemaking,

thereby creating an economic opportunity for the emissions monitoring industry.

Compliance costs

The Board does not anticipate additional costs from

these proposed VOC emission reduction measures for the

owner and operator of this Title V facility which is

already subject to the EPA’s 2001 NESHAP HAP emission control requirements. These applicable requirements

are incorporated in the Federally-enforceable Title V

permit issued by the Department to the owner and

operator on January 23, 2008. Therefore, there would not

be additional compliance costs to the owner and operator

of this source from implementation of this proposed

rulemaking. It is possible that the proposed rulemaking

would also affect owners and operators of other fiberglass

boat manufacturing facilities that have not yet been

identified, because the HAP emission reduction measures

of the 2001 NESHAP do not apply to the owners and

operators of area sources (that is, sources that emit less

than 10 tpy of any single listed HAP or less than 25 tpy

of any combination of HAPs). Owners and operators of

area source fiberglass boat manufacturing facilities are,

therefore, not currently required to implement the HAP

emission reduction measures provided in the 2001

NESHAP, which are also included in the 2008 Fiberglass

Boat Manufacturing Materials CTG as measures for

reducing emissions of VOCs from sources that meet the

applicability threshold recommended by the EPA in the

CTG.

The owner and operator of a facility that is not subject

to the 2001 NESHAP that would be subject to the

proposed rulemaking would be expected to incur little, if

any, cost to implement the requirements of the proposed

rulemaking. The proposed rulemaking provides as one

compliance option the use of individually-compliant resin

and gel coat materials in subsection (f)(1), and requires

the use of compliant cleaning solvents in subsection (l).

Open molding resin, gel coat and cleaning materials that

are compliant with the HAP content limits in the 2001

NESHAP and with the proposed rulemaking VOC content

limits in subsection (a) are readily available to all sizes of

facilities. Further, the industry has experienced a shift to

non-atomizing resin application methods that are required to comply with the HAP emission reduction requirements in the 2001 NESHAP and which are included

in the proposed rulemaking. This shift has occurred at all

sizes of facilities across the United States because of the

productivity and economic benefits of using non-atomizing

methods over conventional atomizing methods.

The proposed rulemaking would provide flexibility by

allowing compliance through averaging the VOC emission

rates of open molding resin and gel coat materials in

subsection (f)(2) in addition to choice of application technology. A third compliance option, the use of a VOC

emissions capture system and add-on air pollution control

device, is provided in subsection (f)(3). However, because

of the wide availability and lower cost (compared to

add-on controls) of compliant VOC content materials and

alternative application methods, compliant materials and

methods are generally used to reduce VOC emissions

from fiberglass boat manufacturing facilities.

Emission limitations established by this proposed rulemaking would not require the submission of applications

for amendments to existing operating permits. These

requirements would be incorporated as applicable requirements at the time of permit renewal, if less than 3 years

remain in the permit term.

New legal, accounting or consulting procedures would

not be required.

Compliance assistance plan

The Department plans to educate and assist the public

and regulated community in understanding the proposed

requirements and how to comply with them. This would

be accomplished through the Department’s ongoing compliance assistance program. The Department would also

work with the Small Business Assistance Program to aid

the facilities less able to handle permitting matters with

in-house staff.

Paperwork requirements

The owner and operator of an affected fiberglass boat

manufacturing source would be required to keep records

of information for open molding resin and gel coat

materials and cleaning materials, as applicable, sufficient

to demonstrate compliance with the requirements of this

section. The proposed rulemaking would require monthly

records of certain VOC content information or composite

vapor pressure, as applicable. Records of calculations

performed for each applicable requirement under subsections (f), (h) and (j) would be required, as well as records

of the sampling and testing performed in accordance with

subsection (n). The records required in the proposed

rulemaking must be maintained for 2 years unless a

longer period is specified by a plan approval or operating

permit issued under Chapter 127 (relating to construction, modification, reactivation and operation of sources)

and submitted to the Department in an acceptable format

upon receipt of a written request.

G. Pollution Prevention

The Pollution Prevention Act of 1990 (42 U.S.C.A.

§§ 13101—13109) established a National policy that promotes pollution prevention as the preferred means for

achieving state environmental protection goals. The Department encourages pollution prevention, which is the

reduction or elimination of pollution at its source, through

the substitution of environmentally friendly materials,

more efficient use of raw materials and the incorporation

of energy efficiency strategies. Pollution prevention practices can provide greater environmental protection with

greater efficiency because they can result in significant

cost savings to facilities that permanently achieve or

move beyond compliance.

This proposed rulemaking would help ensure that the

citizens and the environment of this Commonwealth

experience the benefits of reduced emissions of VOCs and

HAPs from fiberglass boat manufacturing open molding

resin, gel coat and cleaning materials. Although the

proposed rulemaking is designed primarily to address

ozone air quality, the reformulation or substitution of

low-VOC content open molding resin and gel coat materials, and low-VOC content or low vapor pressure cleaning

materials, to meet the VOC content limits applicable to

users may also result in reduction of HAP emissions,

which are also a serious health threat. The reduced levels

PENNSYLVANIA BULLETIN, VOL. 44, NO. 29, JULY 19, 2014
also benefit water quality through reduced loading on

water treatment plants and in reduced quantities of high

VOC-content and HAP-content solvents leaching into the

ground.

The proposed rulemaking provides as one compliance

option that open molding resin and gel coat materials

used in fiberglass boat manufacturing processes in this

Commonwealth would meet specified limits for VOC

content, usually through substitution of low VOC-content

solvents or water for the high VOC-content solvents, and

that they be applied using specified application methods.

Further, the proposed rulemaking would require the

owner and operator of a source subject to this section to

ensure that resin and gel coat containers with a capacity

equal to or greater than 55 gallons (208 liters), including

those used for onsite mixing of putties and polyputties,

have a cover in place at all times with no visible gaps,

except when materials are being manually added or

removed from a container or when mixing equipment is

being placed in or removed from a container.

The proposed rulemaking additionally requires the use

of low-VOC content or low vapor pressure cleaning materials, and work practice standards for the storage and

handling of cleaning materials. The proposed rulemaking

would also require the owner and operator of a source

subject to this section to ensure that the VOC content of

cleaning materials used for routine application equipment

cleaning is equal to or less than 5% by weight or has a

composite vapor pressure equal to or less than 0.50

mmHg at 68°F and use only non-VOC-containing solvent

to remove cured resin or gel coat residue from application

equipment.

monomer VOC content limits in Table I do not apply to a

tooling or production material used for the following

purposes:

(1) A production resin, including a skin coat resin, that

must meet a specification for use in a military vessel or

must be approved by the United States Coast Guard for

use in the construction of a lifeboat, rescue boat or

life-saving appliance approved under 46 CFR Chapter 1,

Subchapter Q (relating to equipment, construction, and

materials: specifications and approval) or the construction

of a small passenger vessel regulated under 46 CFR

Chapter 1, Subchapter T (relating to small passenger

vessels (under 100 gross tons)). A production resin that

meets one or more of these criteria shall be applied with

non-atomizing resin application equipment.

(2) A production or tooling resin or a pigmented, clear

or tooling gel coat used for repair and touch up of a part

or a mold, if the weight used of resin and gel coat

materials that meet one or more of these criteria does not

exceed 1% by weight of the total resin and gel coat

material used at a facility on a 12-month rolling-average

basis.

(3) Pure 100% vinylester resin used for a skin coat, if

the pure 100% vinylester resin used for the skin coat is

applied with non-atomizing resin application equipment,

and the weight used of resin materials meeting this

criterion does not exceed 5% by weight of the total resin

used at a facility on a 12-month rolling-average basis.

(k) Work practices for resin and gel coat materials. The

owner or operator of a facility subject to this section shall

ensure that resin and gel coat containers with a capacity

equal to or greater than 55 gallons (208 liters), including

those used for onsite mixing of putties and polyputties,

have a cover in place at all times with no visible gaps,

except when materials are being manually added or

removed from a container or when mixing equipment is

being placed in or removed from a container.

(l) VOC content limits and work practices for cleaning

materials. The owner or operator of a facility subject to

this section shall comply with the following VOC content

limits and work practices for VOC-containing cleaning

materials:

(1) Ensure that the VOC content of cleaning solvents

used for routine application equipment cleaning is equal

to or less than 5% by weight or has a composite vapor

pressure equal to or less than 0.50 mmHg at 68°F.

(2) Use only non-VOC-containing solvent to remove

cured resin or gel coat from application equipment.

(m) Compliance and monitoring requirements. The

owner or operator of a facility subject to this section shall:

(1) Use the test methods and procedures in subsection

(n) to determine the monomer VOC content of resin and

gel coat material.

(2) Equip add-on air pollution control devices with the

applicable monitoring equipment. The monitoring equipment shall be installed, calibrated, operated and maintained according to manufacturer’s specifications at all

times that the add-on air pollution control device is in

use.

(n) Sampling and testing. The owner or operator of a

facility subject to this section shall perform sampling and

testing as follows:

(1) Use one or more of the following methods to

determine the monomer VOC content of a resin or gel

coat.

(i) SCAQMD Method 312-91, Determination of Percent

Monomer in Polyester Resins.

(ii) Manufacturer’s formulation data.

(iii) Other test methods or data demonstrated to provide results that are acceptable for purposes of determining compliance with this section if prior approval is

obtained in writing from the Department and the United

States Environmental Protection Agency.

(2) Use the test methods and procedures specified in

Chapter 139 (relating to sampling and testing) for sampling and testing of add-on air pollution control devices.

(o) Recordkeeping requirements. The owner or operator

of a facility subject to this section shall maintain monthly

records sufficient to demonstrate compliance with this

section. The records must include the following information:

(1) The name and identification number of each resin

and gel coat.

(2) The total quantity of atomized molding production

resin, non-atomized production resin, pigmented gel coat,

clear gel coat, atomized tooling resin, non-atomized tooling resin and tooling gel coat used per month.

(3) The monomer VOC content for each resin and gel

coat.

(4) The non-monomer VOC content for each resin and

gel coat.

(5) The calculations performed for each applicable requirement under subsections (f), (h) and (j).

(6) The name and identification number only for each

resin used in accordance with subsection (j)(1). The

records specified in paragraphs (1)—(5) do not apply to

resins used in accordance with subsection (j)(1).

(7) The name, identification number and VOC content

or composite vapor pressure for each cleaning solvent

used for routine application equipment cleaning.

(8) The information required by the plan approval

issued under subsection (g), as applicable.

(9) The results of sampling and testing performed in

accordance with subsection (n).

(p) Reporting requirements. The records shall be maintained for 2 years unless a longer period is required by an

order issued by the Department or a plan approval or

operating permit issued under Chapter 127 (relating to

construction, modification, reactivation and operation of

sources). The records shall be submitted to the Department in an acceptable format upon receipt of a written

request.
