Box 8468, Harrisburg, PA 17105-8468, (717) 772-3436; or Kristen Furlan, Assistant Director, Bureau of Regulatory Counsel, Rachel Carson State Office Building, P. O. Box8464, Harrisburg, PA 17105-8464, (717) 787-7060. Information regarding submitting comments on this proposedrulemaking appears in Section J of this preamble. Persons with a disability may use the Pennsylvania AT&T Relay Service, (800) 654-5984 (TDD users) or (800) 654- 5988 (voice users). This proposed rulemaking is availableon 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 emitteddirectly 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 (NO

x ) 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 2008Fiberglass 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; NO

x ; 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 atsufficiently high concentrations can produce a wide variety of harmful effects. At elevated concentrations, groundlevel ozone can adversely affect human health, animalhealth, 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 andin 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 byimplementing 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 RACTlimits 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 NESHAPestablished 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 reasonablyavailable considering technological and economic feasibility.’’ See State Implementation Plans; General Preamble for Proposed Rulemaking on Approval of Plan Revisionsfor 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 availablecontrol 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, EPA453/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 Nationalregulations 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 theCAA 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 MaterialsCTG 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 theproposed 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, whichare also included in the 2008 Fiberglass Boat Manufacturing Materials CTG as measures for reducing emissionsof 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 existingsources 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 andto satisfy related CAA requirements in this Commonwealth. If published as a final-form regulation in the Pennsylvania Bulletin , this proposed rulemaking will besubmitted to the EPA as a revision to the Commonwealth’s SIP.

The proposed rulemaking was discussed with the AirQuality 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 toforward 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 materialsUnder 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 fromthe 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 healthyindividuals 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 thestandards 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 inreducing 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 inthis 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 NAAQSand 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 monitoringsystem 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 isalready 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 tonon-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 insubsection (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. Theserequirements 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 wouldbe 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 calculationsperformed 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 operatingpermit 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 forachieving 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 incorporationof 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 oflow-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 of high VOC-content and HAP-content solvents would 

### 4506 PROPOSED RULEMAKING

**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 useof 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.

H. Sunset Review

This regulation will be reviewed in accordance with the sunset review schedule published by the Department to determine whether it effectively fulfills the goals for which it was intended.

I. Regulatory Review

Under section 5(a) of the Regulatory Review Act (71P. S. § 745.5(a)), on July 8, 2014, the Department submitted a copy of this proposed rulemaking and a copy of a Regulatory Analysis Form to the Independent Regulatory Review Commission (IRRC) and to the Chairpersons of the House and Senate Environmental Resources and Energy Committees. A copy of this material is available to the public upon request.

Under section 5(g) of the Regulatory Review Act, IRRCmay convey any comments, recommendations or objections to the proposed rulemaking within 30 days of theclose of the public comment period. The comments, recommendations or objections must specify the regulatory review criteria which have not been met. The Regulatory Review Act specifies detailed procedures for review, priorto final publication of the rulemaking, by the Department, the General Assembly and the Governor of comments, recommendations or objections raised.

J. Public Comments

Interested persons are invited to submit written comments, suggestions or objections regarding the proposedrulemaking to the Environmental Quality Board. Comments, suggestions or objections must be received by theBoard by September 22, 2014.
