# PROPOSED RULEMAKING

ENVIRONMENTAL QUALITY BOARD

[ 25 PA. CODE CHS. 121, 129 AND 130 

### ] Adhesives, Sealants, Primers and Solvents

The Environmental Quality Board (Board) proposes toamend Chapters 121 and 129 (relating to general provisions; and standards for sources) and to add Subchapter D (relating to adhesives, sealants, primers and solvents) to Chapter 130 (relating to standards for products), to read as set forth in Annex A.

The proposed rulemaking will add definitions to § 121.1 (relating to definitions) for approximately 56 newterms, including those that relate to the adhesive, sealant, primer and solvent product categories that will be regulated under § 129.77 (relating to control of emissionsfrom the use or application of adhesives, sealants, primers and solvents) and Chapter 130, Subchapter D, and will amend definitions for nine existing terms to provide clarity.

The proposed rulemaking will add § 129.77 to regulate the owner or operator of a facility or stationary source that uses or applies, on or after April 15, 2010, a regulated adhesive, sealant, adhesive primer or sealantprimer product. The proposal will adopt emission standards and volatile organic compound (VOC) content limits for the industrial or commercial use or application of 37categories of adhesive, sealant, adhesive primer or sealant primer products, and adhesive or sealant products applied to particular substrates. The proposal will also include requirements for the use of surface preparation solvents and cleanup solvents. Owners and operators using noncomplying products will have the option to use add-on controls as a compliance alternative rather than switching to complying products.

The proposal will add Subchapter D to Chapter 130 to adopt emission standards and VOC content limits for thesale, supply, offer for sale, manufacture, use or application of 37 categories of adhesive, sealant, adhesive primerand sealant primer products; adhesive and sealant products applied to certain substrates; and surface preparation solvents and cleanup solvents. The requirements of the proposed Chapter 130, Subchapter D, will apply to a person who, on or after April 15, 2010, sells, supplies, offers for sale or manufactures for sale an adhesive,sealant, adhesive primer, sealant primer, surface preparation solvent or cleanup solvent product for industrial or commercial use or application in this Commonwealth. The requirements will also apply to a person who uses or applies, for compensation, an adhesive, sealant, adhesive primer or sealant primer product; adhesive or sealant products applied to particular substrates; or surface preparation solvent or cleanup solvent products in this Commonwealth.

This proposal was adopted by the Board at its meeting on December 16, 2008.

C. Statutory Authority

This 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.

D. Background and Purpose

The purpose of this proposed rulemaking is to establish a program to limit the emissions of VOCs from the industrial and commercial use and application of certain adhesive, sealant, adhesive primer and sealant primerproducts; adhesive and sealant products applied to certain substrates; and surface preparation solvent and cleanup solvent products. This proposed rulemaking also extends these product requirements to the owners or operators of facilities that use these products as part of amanufacturing process and provides them with an alternative compliance method of using add-on air pollution controls in place of complying products. VOCs are a precursor for ozone formation. Ground-level ozone is not emitted directly by adhesives, sealants, primers andsolvents to the atmosphere, but is formed by a photochemical reaction between VOCs and nitrogen oxides (NOx) in the presence of sunlight.

The United States Environmental Protection Agency (EPA) is responsible for establishing National Ambient Air Quality Standards (NAAQS) for six criteria pollutants considered harmful to public health and the environment: ozone, particulate matter, NOx, carbon monoxide, sulfur dioxide and lead. The Federal Clean Air Act (42 U.S.C.§§ 7401—7671q) established two types of NAAQS: primary standards, limits set to protect public health; and secondary standards, limits set to protect public welfare, including protection against visibility impairment and from damage to animals, crops, vegetation and buildings. In 1997, the EPA established the 8-hour ozone NAAQS, a more protective ozone primary and secondary NAAQS to protect public health and welfare.

When ground-level ozone is present in concentrations in excess of the Federal health-based 8-hour NAAQS for ozone, public health and welfare are adversely affected.Ozone exposure correlates to increased respiratory disease and higher mortality rates. Ozone can inflame and damage the lining of the lungs. Within a few days, the damaged cells are shed and replaced, much like the skin peels after sunburn. Over a long time period, lung tissue may become permanently scarred, resulting in permanent 

### 1636

PENNSYLVANIA BULLETIN, VOL. 39, NO. 14, APRIL 4, 2009loss of lung function and a lower quality of life. When ambient ozone levels are high, more people with asthma have attacks that require a doctor ’ s attention or use of medication. Ozone also makes people more sensitive to allergens including pet dander, pollen and dust mites, all of which can trigger asthma attacks.

The EPA has concluded that there is an association between high levels of ambient ozone and increased hospital admissions for respiratory ailments including asthma. 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 ozone while engaged in activities that involve physical exertion. High levels of ozone also affect animals in ways similar to humans.

In addition to causing adverse human and animal health effects, the EPA has concluded that ozone affectsvegetation and ecosystems, leading to reductions in agricultural crop and commercial forest yields by destroying chlorophyll; reduced growth and survivability of tree seedlings; and increased plant susceptibility to disease, pests, and other environmental stresses, including harsh weather. In long-lived species, these effects may become evident only after several years or even decades and have the potential for long-term adverse impacts on forest ecosystems. Ozone damage to the foliage of trees andother plants can decrease the aesthetic value of ornamental species used in residential landscaping, as well as the natural beauty of parks and recreation areas. Throughdeposition, ground-level ozone also contributes to pollution in the Chesapeake Bay. The economic value of some welfare losses due to ozone can be calculated, such as crop yield loss from both reduced seed production andvisible injury to some leaf crops, including lettuce, spinach and tobacco, as well as visible injury to ornamental plants, including grass, flowers and shrubs. Other types of welfare loss may not be quantifiable, such as the reduced aesthetic value of trees growing in heavily visited parks.

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 ozoneair quality nonattainment in this Commonwealth is necessary to protect the public health and welfare, animal and plant health and welfare and the environment.

In 2004, the EPA designated 37 counties in this Commonwealth as 8-hour ozone nonattainment areas for the 1997 8-hour ozone NAAQS. The proposed rulemaking willsupport the 8-hour ozone NAAQS attainment demonstrations for the Philadelphia 5-county area (comprising Bucks, Chester, Delaware, Montgomery and Philadelphia Counties) and the 7-county Pittsburgh-Beaver ValleyArea. The proposed rulemaking will also provide additional reductions to support the maintenance plans for the remaining areas recently redesignated to attainment of the 8-hour ozone health-based standard.

Further, the proposed rulemaking will provide additional reductions of VOC emissions to meet the revised 8-hour ozone standard of 0.075 part per million (ppm), down from 0.08 ppm, promulgated by the EPA on March27, 2008 (73 FR 16436). Recommendations for attainment, nonattainment and unclassifiable areas under the new, more stringent 8-hour ozone standard must be submitted to the EPA in March 2009; final action by the EPA is anticipated in March 2010. The designations will take effect 60 days after the EPA publishes a notice in the Federal Register.

There are no Federal limits for the larger container sizes of adhesive, sealant, adhesive primer and sealant primer products that will be subject to regulation underthis proposed rulemaking. The staff of the Ozone Transport Commission (OTC) and Member States and the District of Columbia formed a workgroup to discuss control measures for the sale, offer for sale, supply, manufacture, industrial use and commercial application of solvent-based adhesives, sealants and primers during a series of conference calls and workshops held from the spring of 2004 through the autumn of 2006. The OTC workgroup collected and evaluated information regarding emission benefits, cost-effectiveness and implementation issues.

This proposed rulemaking is based on emission reduction measures recommended by the OTC in its 2006 Model Rule for adhesives, sealants and primers, which is based on the 1998 reasonably available control technology (RACT) and best available retrofit control technology (BARCT) determination by the California Air Resources Board (CARB) for the industrial and commercial use andapplication of adhesives, sealants and primers. The Department has reviewed the OTC 2006 Model Rule and the CARB RACT/BARCT for their applicability to the ozone reduction measures necessary for this Commonwealth.

The OTC workgroup received comments on the 2006Model Rule from the National Paint and Coatings Association, the Adhesive and Sealant Council, Inc., andLORD Corporation. The Department reviewed these comments for applicability to the development of this Pennsylvania-specific proposed rulemaking.

The Department consulted with the Air Quality Technical Advisory Committee (AQTAC) on the proposed rulemaking on March 27 and May 23, 2008. The AQTAC unanimously concurred with the Department ’ s recommendation to seek the Board’s approval of the proposed rulemaking, asking the Department to consider reducing recordkeeping requirements for some product users and the special needs of segments of the roofing industry. The Department also consulted with the Citizen ’ s Advisory Council on March 18 and May 20, 2008, and with the Small Business Compliance Advisory Committee on April 23, 2008.

The proposed rulemaking is reasonably necessary to achieve and maintain the health-based 8-hour ozoneNAAQS in this Commonwealth. This proposed rulemaking is consistent with regulatory initiatives that willbe undertaken by other jurisdictions in the Ozone Transport Region (OTR). The proposed rulemaking, when adopted, will be submitted to the EPA as a revision to the Commonwealth ’ s State Implementation Plan.
E. Summary of Regulatory Requirements

PENNSYLVANIA BULLETIN, VOL. 39, NO. 14, APRIL 4, 2009membrane sealant and single-ply roof membrane adhesive primer to address rubber roofing adhesive curing issues during the colder months of the year. The phase-in strategy is proposed to provide time for product researchand development, and for the training of roofing contractors in the effective application of new formulations for use in cold temperatures. According to the Ethylene Propylene Diene Membrane (EPDM) Roofing Association (ERA), compliance with the OTC 2006 Model Rule VOC content limit of 250 grams per liter for single-ply roof membrane installation or repair bonding adhesive is notcurrently possible in the colder months, as roofing adhesives meeting this limit do not properly cure at temperatures below 40 ° F. A phase-in strategy has been adopted in Connecticut and is also being considered by New Jersey, New York and Rhode Island and the District of Columbia.

Proposed § 129.77(n) provides an exemption from the requirements of § 129.77 if the total VOC emissions from all adhesives, sealants, adhesive primers and sealant primers used at the facility are less than 200 pounds or an equivalent volume, per calendar year. An owner or operator claiming exemption under this subsection shall record and maintain operational records sufficient to demonstrate compliance with this exemption.

Proposed § 129.77(o) provides an exemption for the use of a noncomplying adhesive, sealant, adhesive primer, sealant primer, surface preparation solvent or cleanup solvent if the total volume of noncomplying products applied facility-wide does not exceed 55 gallons per calendar year. An owner or operator claiming exemptionunder this subsection shall record and maintain operational records sufficient to demonstrate compliance with this exemption.

Proposed § 129.77(p) specifies that each owner or operator subject to this section shall maintain records demonstrating compliance with this section, includingspecific information. Several members of AQTAC questioned the necessity of paragraph (6), which requires that the owner or operator maintain records of the volume used of each of the regulated products. These members suggested that keeping records of small quantities ofmiscellaneous product use and keeping records of materials used as opposed to materials purchased would be unnecessary and burdensome. These members questioned who should keep records for materials used by outside contractors (for example, roofers and piping contractors). They suggested either revising paragraph (6) to require records of volume of product ‘‘ purchased’’ instead of volume of product ‘‘ used, ’’ or deleting paragraph (6). They suggested that a certification that compliant products were used would suffice. Other members of AQTAC thought paragraph (6) should remain intact because of the information it would provide about actual emissions. The Board seeks comment on the alternative approaches suggested by members of AQTAC.

Proposed § 129.77(q) provides recordkeeping requirements for the person conducting testing on products that are subject to the laboratory testing exemption.

Proposed § 129.77(r) specifies that all records made todetermine compliance with this section shall be maintained onsite for at least 5 years from the date the record is created and made available to the Department upon request.

Proposed § 129.77(s) specifies, with certain exceptions,that the VOC and solids content of all nonaerosol adhesives, sealants, adhesive primers, sealant primers, surface preparation solvents and cleanup solvents shall be determined using either EPA Reference Method 24 or SCAQMD Method 304, including updates and revisions.

Proposed § 129.77(t) specifies that the identity and concentration of exempt organic compounds shall be determined using either ASTM D4457 or SCAQMD Method 303, including updates and revisions.

Proposed § 129.77(u) specifies that the VOC content of a plastic cement welding adhesive or primer shall bedetermined using SCAQMD Method 316A, including updates and revisions.

Proposed § 129.77(v) specifies that to determine if a diluent is a reactive diluent, the percentage of the reactive organic compound that becomes an integral part of the finished material shall be determined using SCAQMD Method 316A, including updates and revisions.

Proposed § 129.77(w) specifies the procedure for determining the composite vapor pressure of organic compounds in cleaning materials.

Proposed § 129.77(x) specifies that the vapor pressure of each component in the cleaning material subject to the requirement of § 129.77(w) may be determined from either ASTM 2879 or one or more of the listed references, including updates and revisions.

Proposed § 129.77(y) specifies that if air pollution control equipment is used to meet the requirements of this section, the owner or operator shall determine the capture efficiency and the control efficiency using certain procedures.

Proposed § 129.77(z) specifies that the active and passive solvent losses from spray gun cleaning systems shall be determined using the SCAQMD method, General Test Method for Determining Solvent Losses from Spray Gun Cleaning Systems, including updates and revisions.

Proposed § 129.77(aa) specifies the method for calculating the VOC content of adhesive, sealant, adhesive primer or sealant primer products that do not contain reactive diluents.

Proposed § 129.77(bb) specifies the method for calculating the VOC content for adhesive, sealant, adhesive primer or sealant primer products that contain reactive diluents.

Proposed § 129.77(cc) specifies the method for calculating the VOC content for low-solids adhesive, sealant, adhesive primer or sealant primer products.

Proposed § 129.77(dd) specifies the method for calculating percent VOC by weight.

Several members of AQTAC questioned the necessity of § 130.704(b)(6), which requires that the owner or operator maintain records of the volume used of each of theregulated products. These members suggested that keeping records of small quantities of miscellaneous product use and keeping records of materials used as opposed tomaterials purchased would be unnecessary and burdensome. These members questioned who should keep records for materials used by outside contractors (for example, roofers and piping contractors). They suggested either revising paragraph (6) to require records of volume of product ‘‘ purchased’’ instead of volume of product

‘‘ used’’ , or deleting paragraph (6). They suggested that a certification that compliant products were used would suffice. Other members of AQTAC thought paragraph (6) should remain intact because of the information it wouldprovide about actual emissions. The Board seeks comment on the alternative approaches suggested by members of AQTAC.

Proposed § 130.705 specifies the compliance procedures, test methods and calculations that shall be used to determine the VOC, solids content and exempt organiccompound content of adhesives, sealants, adhesive primers, sealant primers, surface preparation solvents and cleanup solvents subject to this subchapter.

Proposed § 130.706 (relating to container labeling)specifies that on and after April 15, 2010, each manufacturer of an adhesive, sealant, adhesive primer or sealant primer product subject to this subchapter shall display certain information on the product container or label.

Consistent with the OTC 2006 Model Rule, the proposed rulemaking does not include a date-coding requirement. This presents problems for tracking the sale anduse of product manufactured before the proposed regulatory compliance date of April 15, 2010. The Board seeks comment on whether the final-form regulations shouldinclude a date-coding requirement to facilitate enforcement of the regulations and the sale and use of product manufactured before the proposed compliance date ofApril 15, 2010 (sell-through and use-through). The Department will also consult with other OTR states on this issue.

F. Benefits, Costs and Compliance

Benefits
The citizens of this Commonwealth will be the majorbenefactors from this proposed rulemaking through reduced exposure to a variety of solvents, including hazardous air pollutants (HAPs), that are used in a variety of adhesive, sealant, adhesive primer and sealant primer products. These proposed amendments will result in improved air quality by reducing VOC ozone precursor emissions from the industrial and commercial use and application of the regulated adhesive, sealant and primer products. Benefits will also occur from reduced VOCcontent in surface preparation solvent and cleanup solvent products. The proposed amendments will encourage the implementation of new technologies and practices,which will reduce emissions of VOCs and HAPs throughout this Commonwealth.

Compliance Costs
The cost of complying with the new requirementsincludes the cost of using or developing alternative product formulations, including product formulations for lowVOC or water-based adhesive, sealant, adhesive primer, sealant primer, surface preparation solvent and cleanup solvent products. Based on information provided by the Ventura County Air Pollution Control District (VCAPCD), the CARB determined that the cost-effectiveness of the VCAPCD adhesives rule, which formed the basis of the CARB 1998 RACT/BARCT Determination upon which the OTC 2006 Model Rule is based, ranges from a savings of $1,060 per ton to a cost of $2,320 per ton of VOC reduced. Any costs are likely to be less in the OTR, because some of the research and reformulation costs incurred for products sold in California will not have to be incurred again for products sold in the OTR. The CARB also reports a cost-effectiveness of $9,000 to $110,000 per tonof VOC reduced should the use of add-on control equipment to comply with the requirements be necessary.

The Department anticipates similar costs in this Commonwealth. MACTEC Federal Programs, a consultant to the OTC, indicated in its report, ‘‘ Identification andEvaluation of Candidate Control Measures, Final Technical Support Document, ’’ that the requirements of the OTCAdhesives, Sealants and Primers Model Rule would reduce emissions of VOC by approximately 21.8 tons persummer day (tpsd) in this Commonwealth. Ozone monitoring season (April 1 through October 31) VOC emission reductions from this rulemaking would be approximately 4,665.2 tons (21.8 tpsd × 214 ozone monitoring season days). Assuming that there are approximately 12 million people living in this Commonwealth, the average ozone 

### PROPOSED RULEMAKING 1641

PENNSYLVANIA BULLETIN, VOL. 39, NO. 14, APRIL 4, 2009season VOC emissions reduction is calculated to be 0.78 pound of VOC emissions reduced per resident of this Commonwealth.

The total ozone monitoring season costs are calculated by multiplying the maximum estimated cost of $2,320 per ton of VOC emissions reduced times 4,665.2 tons per ozone monitoring season, which equals approximately $10,823,264 per ozone monitoring season. The maximumozone monitoring season cost per resident of this Commonwealth would be approximately $0.90.

Annual VOC emission reductions from this rulemaking would be approximately 7,957 tons (21.8 tpsd × 365 days per year) or 1.3 pounds of VOC emissions reduced per resident of this Commonwealth per year. Annual costs would be $2,320 per ton of VOC emissions reduced times 7,957 tons per year or $18,460,000. The maximum annualcost per resident of this Commonwealth would be approximately $1.55.

Cost savings could be incurred if reformulated products are less expensive, with the possibility that residents of this Commonwealth could realize savings of $0.41 per ozone season per resident ($1,060 × 4,665.2 tons divided by 12,000,000 residents) or $0.70 annually per resident ($1,060 × 7,957 tons divided by 12,000,000 residents).

Owners or operators of facilities or stationary sources using regulated adhesive, sealer, primer and solvent products could incur costs of $9,000 to $110,000 per ton of VOC emissions reduced, should the use of add-on control equipment be necessary to comply with the requirements of this rulemaking, based on CARB estimates. However,fewer than 40 facilities in this Commonwealth are expected to be required to comply with this rulemaking. Most of the affected facilities already have permits thatestablish requirements for the use of the adhesive, sealant, primer and solvent products proposed for regulation in this rulemaking.

Compliance Assistance Plan The Department plans to educate and assist the public and regulated community in understanding the newly revised requirements and how to comply with them. This will be accomplished through the Department ’ s ongoing Regional compliance assistance program.

Paperwork Requirements The proposed rulemaking includes recordkeeping and reporting requirements in § 129.77 for affected owners and operators of facilities that use or apply the regulatedadhesive, sealant, adhesive primer, sealant primer, surface preparation solvent and cleanup solvent products. These recordkeeping requirements include keeping lists of each regulated product in use or in storage; a data sheet or material list for each product that provides the name of the product, manufacturer ’ s identification, and use for the product; the VOC content for the product as supplied; the catalysts, reducers or other components used and the mix ratio; the VOC content or vapor pressure of each product as applied, if solvent or other VOC is added to the product before application; and the volume used of each product.

For an adhesive, sealant, adhesive primer and sealantprimer product subject to the laboratory testing exemption, the person conducting the testing shall make and maintain records of all products used, including the following information: the product name; the product category of the material or type of application; and the VOC content of the material. Records made to determine compliance with § 129.77 shall be maintained onsite for at least 5 years from the date the record is created and made available to the Department upon request.

The proposed rulemaking includes recordkeeping and reporting requirements in Chapter 130, Subchapter D fora person who sells, supplies, offers for sale or manufactures for sale for use in this Commonwealth an adhesive,sealant, adhesive primer, sealant primer, surface preparation solvent or cleanup solvent product subject to thissubchapter. The person shall maintain records demonstrating compliance with this subchapter, including the following information: a data sheet or material list which provides the material name, manufacturer identification and material application for each product; the VOC content of each product, as supplied; and the number of gallons of product sold in this Commonwealth.

A person who uses or applies an adhesive, sealant,adhesive primer, sealant primer, surface preparation solvent or cleanup solvent product subject to Subchapter D shall maintain records demonstrating compliance with this subchapter, including the following information: a list of each adhesive, sealant, adhesive primer, sealant primer, surface preparation solvent and cleanup solvent product in use and in storage; a data sheet or material list which provides the product name, manufacturer identification and use or material application for each product included on the list; the VOC content of each product on the list, as supplied; catalysts, reducers or other components used and the mix ratio; the VOC content or vapor pressure of each product on the list, as applied, if solvent or other VOC is added to the product before application; and the volume used of each product on the list.

For an adhesive, sealant, adhesive primer and sealantprimer product subject to the laboratory testing exemption of § 130.703(a)(1), the person conducting the testing shall make and maintain records of all materials used, including the following information: the product name;the product category of the material or type of application; and the VOC content of the material.

Records made to determine compliance with Chapter 130, Subchapter D shall be maintained for at least 5 years from the date the record is created and made available to the Department upon request.
G. Pollution Prevention

The Federal 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 proposal has incorporated the following pollution prevention incentives:

The proposed amendments will assure that the citizens and the environment of this Commonwealth experience the benefits of reduced emissions of VOCs and HAPs from the industrial and commercial use or application of low-VOC adhesive, sealant, adhesive primer, sealant primer, surface preparation solvent and cleanup solvent products. Although the proposed requirements are to 

### 1642 PROPOSED RULEMAKING

PENNSYLVANIA BULLETIN, VOL. 39, NO. 14, APRIL 4, 2009address ground-level ozone air quality by reducing emissions of ozone precursors, the reformulation of products to meet the VOC content limits will also result in the reduction of HAP emissions. The proposed amendments will result in improved indoor and outdoor air quality for all citizens of this Commonwealth by reducing VOC ozone precursor emissions and HAP compounds. The reduced levels of HAPs will also benefit water quality throughreduced loading on water treatment plants and in reduced quantities of HAP compounds in spillage on the ground.

application of adhesives, sealants, primers and solvents. (a) This section applies to the owner or operator of a facility that uses or applies one or more of the following on or after April 15, 2010: (1) An adhesive, sealant, adhesive primer or sealant primer subject to the emission standards in Table V.

(2) An adhesive or sealant product applied to the listed substrate subject to the emission standards in Table VI.

(3) A surface preparation solvent or cleanup solvent. (b) On or after April 15, 2010, an owner or operator of a facility may not use or apply at the facility an adhesive, sealant, adhesive primer or sealant primer that exceeds the applicable VOC content limit in Table V or VI, except as provided elsewhere in this section.

(c) On or after April 15, 2010, an owner or operator of a facility may not use or apply at the facility a surface preparation or cleanup solvent that exceeds the applicableVOC content limit or composite vapor pressure requirements of this section, except as provided elsewhere in this section.

(d) The VOC content limits in Table VI for adhesives or sealants applied to particular substrates apply as follows:

(1) If an owner or operator uses an adhesive or sealant subject to a specific VOC content limit in Table V, thespecific limit is applicable rather than the adhesive-tosubstrate limit in Table VI.

(2) If an adhesive is used to bond dissimilar substratestogether, the applicable substrate category with the highest VOC content is the limit for this use.

(e) An owner or operator subject to this section using a surface preparation solvent or cleanup solvent may not:

UTILITY COMMISSION

[L-2008-2069115/57-266] 

### Licensing Requirements for Natural Gas Suppliers

The Pennsylvania Public Utility Commission (Commission) on December 4, 2008, adopted a proposed rulemaking order which revises the Commission ’ natural gas supplier licensing regulations regarding level of security needed and forms of security used to satisfy statutory security requirements for licensing. Executive Summary

In its October 2005 Report to the General Assembly on its investigation into competition in Pennsylvania ’ s retail natural gas market, the Commission found that there was not effective competition in the natural gas retail market based in part on the low number of natural gas suppliers (NGSs) participating in the market. Docket No. I-00040103. The amount of financial security that an NGS needed to provide for licensing was identified as a possible barrier to market entry and participation. See 66 Pa.C.S. § 2208(c)(1)(i).

Based on the Commission ’s finding, a collaborative of stakeholders (SEARCH) was convened to discuss ways to increase effective competition. The report on SEARCH suggested the use of reasonable criteria for adjusting the amount of security required for licensing and the use assecurity of NGS accounts receivable in Purchase of Receivables Programs (POR) as two ways to increase the number of suppliers participating in the retail market. The Commission adopted this suggestion in its Final Search Order and Action Plan, order entered September 11, 2008 at Docket No. I-00040103F0002 and directed that the Commission ’s regulation in 52 Pa. Code § 62.111 (relating bonds and other security) be revised accordingly.

This proposed rulemaking revises § 62.111 to include: (1) the use of NGS accounts receivables in a Commission approved POR program to satisfy part of, or the totalsecurity requirement; (2) the adoption of standard language for financial instruments used for security; and (3) the development of reasonable criteria for a natural gas distribution company (NGDC) to use in adjusting the
