[25 PA. CODE CHS. 121, 129 AND 139]
Surface Coating Processes (RBI # 4)
[29 Pa.B. 1299]
The Environmental Quality Board (Board) proposes to amend Chapters 121, 129 and 139 (relating to general provisions; standards for sources; and sampling testing) to read as set forth in Annex A.
The proposed rulemaking provides procedures for determining compliance with volatile organic compound (VOC) emission limits for the surface coating processes in § 129.52 (relating to surface coating processes). These proposed amendments include an averaging approach for evaluating VOC emissions from diptanks; an exemption for small quantities of coatings; and revision of the existing Table I to express VOC emission standards in surface coating processes in volume-solids-based and weight-solids-based emission limits. The proposed amendments also establish presumptive reasonably available control technology (RACT) requirements for wood furniture manufacturing operations in §§ 129.101--129.107. The presumptive RACT requirements, based on the EPA's Control Techniques Guidelines (CTG), apply Statewide to wood furniture manufacturing facilities with actual or potential emissions of 25 tons per year or more of VOCs.
This proposal was adopted by the Board at its meeting of September 15, 1998.
A. Effective Date
These proposed amendments will be effective immediately upon publication in the Pennsylvania Bulletin as final rulemaking.

C. Statutory Authority
The proposed rulemaking is being made under the authority of section 5(a)(1) of the Air Pollution Control Act (35 P. S. § 4005(a)(1)), which grants to 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
These proposed amendments include regulatory changes which implement the Bureau of Air Quality's Regulatory Basics Initiative (RBI) mandated under the ''Directive on Review of Existing Regulations and Technical Guidance'' issued by Secretary Seif on August 4, 1995, and Executive Order 1996-1 (Regulatory Review and Promulgation). The RBI changes for the surface coating provisions in § 129.52 (relating to surface coating processes) are the fourth in a series of amendments to the air resources regulations. The proposed revisions to § 129.52 delete existing language to adjust coatings to a standard solvent density of 7.36 pounds per gallon and to a solids basis. The proposed amendments calculate and express VOC emission standards in volume-solids-based and weight-solids-based emission limits and add criteria to allow for emission averaging of VOCs from diptanks on a 30-day rolling average basis. An exemption for small quantities of coatings used for touch-up and repair is also included in this proposal.
These proposed amendments establish presumptive RACT requirements for certain wood furniture manufacturing operations. Section 183(a) of the Clean Air Act requires the United States Environmental Protection Agency (EPA) to issue CTG for 11 categories of stationary sources of volatile organic compounds (VOCs). On May 20, 1996, the EPA published a CTG document for control of VOCs from wood furniture manufacturing operations including wood furniture finishing, cleaning and washoff (61 FR 25223, May 20, 1996). The wood furniture manufacturing operations CTG establish a ''presumptive norm'' RACT for the control of affected stationary sources. The standards apply Statewide to wood furniture manufacturing facilities located in the ozone transport region or marginal, moderate, serious and severe ozone nonattainment areas that emit or have the potential to emit 25 tons per year or more of VOCs. The CTG and a model rule for wood furniture manufacturing operations were developed by the EPA after reaching consensus among representatives from the environmental community, the wood furniture industry and State permitting agencies.
On September 27, 1996, the EPA published an addendum to the CTG which specified dates for the adoption and implementation of the standards. The notice required states that had not adopted an EPA-approvable RACT rule for wood furniture manufacturing facilities to submit a RACT rule to the EPA on or before May 20, 1997, as a revision to the State Implementation Plan (SIP). State rules should require affected sources to install and operate required control devices and implement procedures to demonstrate compliance no later than May 20, 1998 (61 FR 50823, September 27, 1996). In keeping with the RBI, the required wood furniture manufacturing provisions shall be no more stringent than the Federal CTG.
The Department consulted with the Air Quality Technical Advisory Committee (AQTAC) during the development of the proposed rulemaking. On January 16, 1998, and May 29, 1998, the AQTAC recommended that the proposed rulemaking be submitted to the Board for consideration. Following promulgation of the proposed amendments to Chapters 121, 129 and 139 the provisions will be submitted to the EPA as a SIP revision.
E. Summary of Regulatory Requirements
This proposed rulemaking implements the fourth series of changes under the Department's RBI for air resources regulations and establishes criteria to implement the presumptive RACT requirements for wood furniture manufacturing operations. The presumptive RACT requirements are governed by limitations on VOC emissions and the implementation of work practice standards. A summary of the proposed rulemaking follows:
Chapter 121. General Provisions
The proposed amendments to § 121.1 (relating to definitions) include the following definitions which are based on 40 CFR Part 63, Subpart JJ (relating to National Emission Standards for Wood Furniture Manufacturing Operations) and the CTG document for the control of VOCs from wood furniture manufacturing operations: ''alternative method,'' ''as applied,'' ''as supplied,'' ''basecoat,'' ''CPDS--certified product data sheet,'' ''coating,'' ''coating solids (or solids),'' ''compliant coating,'' ''continuous coater,'' ''conventional air spray,'' ''enamel,'' ''equivalent method,'' ''MSDS--material safety data sheet,'' ''nonpermanent final finish,'' ''normally closed container,'' ''operating parameter value,'' ''pollution prevention,'' ''sealer,'' ''stain,'' ''strippable spray booth coating,'' ''substrate,'' ''thinner,'' ''touch-up and repair,'' ''washoff operations,'' ''waterborne coating,'' ''wood furniture,'' ''wood furniture component'' and ''wood furniture manufacturing operations.''
This proposed rulemaking deletes the following terms from § 121.1: ''semitransparent spray stains,'' ''semitransparent wiping and glazing stains'' and ''wood cabinet and furniture finishing.''
These proposed amendments also include revisions to the following existing definitions:
''Miscellaneous metal parts and products''--The proposed revisions delete the phrase ''but not limited to'' and expand the Standard Industrial Classification Codes from 3300 through 3900 to 3999.
''Process''--The proposed amendments to the term ''process'' correct a grammatical error and include ''operations'' necessary for the completion of a transformation to produce a physical or chemical change in the definition.
''Surface coating process''--The proposed changes to the definition specify that the surface coating process is the application and solidification of a coating onto or into a substrate as the substrate proceeds through the equipment and activities of the manufacturing process.
''Topcoat''--The proposal deletes the existing definition of ''topcoat'' and defines the term ''topcoat'' as the last film-building coating applied to a substrate in a surface coating process. The term does not include nonpermanent final finishes.
''VOC--Volatile Organic Compound''--The proposed amendment to the VOC definition adds 40 CFR 51.100, the Federal citation for VOCs determined by the EPA Administrator to have negligible photochemical reactivity.
''Washcoat''--The proposed revisions delete ''low solids'' and include a solids content by weight of 12.0% or less in accordance with the ''washcoat'' definition in the CTG and model rule for wood furniture manufacturing operations.
Chapter 129. Sources of VOCs
§ 129.52. Surface coating processes.
The proposed amendments include the following revisions to this section:
§ 129.52(b)(1)--The proposed amendments delete the existing regulatory language requiring adjustment to a standard solvent density and a solids basis. This adjustment is incorporated into revisions to Table I (relating to allowable content of VOCs in surface coatings by process).
§ 129.52(b)(1)(i)--This proposed change adds an equation for calculating the VOC content on the basis of weight of VOC per volume of coating solids to be used in evaluating compliance for Table I categories 1 through 10. This clarification is in response to the RBI report on Regulations Which Lack Clarity. The existing equation in § 129.52(b)(2) is not expressed in a format to allow for easy calculation of compliance.
§ 129.52(b)(1)(ii)--This proposed amendment adds the equation for calculating the VOC content of a dip coating on a 30-day rolling average basis. The methodology for calculating the VOC content includes the gallons of make-up solvent added to the coating in the dip tank over any consecutive 30-day period to replace evaporated solvent. The specific viscosity of the coating being applied would be maintained in accordance with the guidance published in EPA-340/1-86-016, A Guide for Surface Coating Calculations.
§ 129.52(b)(1)(iii)--This proposed amendment adds a simple equation for calculating the VOC content on the basis of weight of VOC per weight of coating solids. This methodology is used to evaluate compliance with Table I, category 11, and with Table IV in the proposed §§ 129.101--129.107.
§ 129.52(b)(1)(iv)--This proposed amendment adds the equation for calculating the VOC content of dip coating during a wood furniture manufacturing on a 30-day rolling average basis. This method of calculating the VOC content includes the gallons of make-up solvent added to the coating in the dip tank over any consecutive 30-day period to replace evaporated solvent and therefore maintain a specific viscosity of the coating being applied, according to guidance published in A Guide for Surface Coating Calculations (EPA-340/1-86-016). The proposed revision also specifies that sampling and testing is done in accordance with the methods in Chapter 139 to reference the various methods, particularly for volume solids analysis, developed by the American Society for Testing and Materials (ASTM) which will be included in revisions to the Source Testing Manual.
§ 129.52(b)(2)--The existing equation for calculating the percentage of emission reductions needed to comply if using control equipment is deleted. A new equation is proposed for calculating the overall efficiency of the control system based on the new units of measurement in Table I (weight of VOC per volume of solids and weight of VOC per weight of solids).
§ 129.52(c)--This proposed amendment deletes the existing list of required records and adds recordkeeping requirements that are appropriate to the required analytical methods used to evaluate compliance as specified in the Source Testing Manual. This proposed change also emphasizes the need for facilities to keep records of volume solids content.
§ 129.52(g)--Moves the existing requirement for maintaining records for 2 years from the existing § 129.52(c) to a separate subsection to emphasize and add clarity to the amendments.
§ 129.52(h)--This proposed amendment adds an exemption from VOC emission limitations for small quantities of coatings used for determination of product quality and commercial acceptance, touch-up and repair and other small quantity coatings. Subsection (h) requires the owner or operator to submit a written request to the Department to exempt quantities of coating which do not exceed 50 gallons a year for a single coating and a total of 200 gallons each year for all coatings combined for the facility. The Department's written approval must be obtained prior to use of the exempted coatings.
Wood Furniture Manufacturing Operations
§ 129.101. General provisions and applicability.
The proposed requirements in § 129.101 (relating to general provisions and applicability) provide that the provisions in §§ 129.101--129.107 apply to each wood furniture manufacturing facility located in a county included in the northeast ozone transport region or in a county designated as severe, serious, moderate or marginal ozone nonattainment and which emits or has the potential to emit 25 tons or more per year of VOCs from wood furniture manufacturing operations. These requirements are in addition to the wood cabinet and furniture finishing provisions in § 129.52. The most stringent VOC emission limitation will apply to a wood furniture manufacturing operation that meets the threshold limits for both § 129.52 and §§ 129.101--129.107.
Subsection (b) requires the owners or operators of existing wood furniture manufacturing operations to also comply with the requirements in § 129.52. If the actual emissions or potential to emit (PTE) for VOCs is 25 tons per year or greater, the owner or operator of the wood furniture manufacturing facility must comply with the requirements of §§ 129.101--129.107 within 1 year from the effective date of the final rulemaking. The compliance deadline does not apply to facilities that have obtained EPA-approved SIP revisions for RACT prior to the adoption of §§ 129.101--129.107 as a final-form regulation. Major VOC-emitting wood furniture manufacturing operations will no longer be subject to the RACT requirements in §§ 129.91--129.95 (relating to stationary sources of NOx and VOCs) because the EPA has issued a CTG for the control of VOC emissions from wood furniture manufacturing operations (61 FR 25223, May 20, 1996).
Subsection (c) provides a compliance deadline for the owner or operator of an existing wood furniture manufacturing facility which increases its actual emissions or its potential to emit to 25 tons per year or more of VOCs from wood furniture manufacturing operations after the effective date of this proposal. Within 1 year after increasing actual VOC emissions or the potential to emit to 25 tons per year or more, the owner or operator of the affected facility must comply with §§ 129.101--129.107. The newly proposed presumptive RACT requirements for wood manufacturing operations would not apply to facilities with EPA-approved SIP revisions for RACT prior to the adoption of this proposal.
The general provisions also exempt from the VOC emission limits in § 129.102, Table IV, a small quantity of coatings used exclusively for determination of product quality and commercial acceptance, touch-up and repair and other small quantity coatings provided use of the coatings is approved in writing by the Department prior to use. Subsection (f) requires the owner or operator to submit a written request to the Department to exempt quantities of coating which do not exceed 50 gallons per year for a single coating and a total of 200 gallons per year for all coatings combined for the facility. The Department's written approval must be obtained prior to use of the exempted coatings.
§ 129.102. Emission standards.
This section lists in Table IV (relating to emission limits of VOC for wood furniture manufacturing sealers, topcoats and strippable spray booth coating, as applied) the emission limits of VOCs for wood furniture manufacturing sealers, topcoats and strippable spray booth coatings that are actually used for coating the substrate. Facility owners or operators are authorized to demonstrate compliance with the emission standards by using either of the following or a combination of the methods including the use of sealers, topcoats and strippable spray booth coatings with a VOC content equal to or less than the standard specified in Table IV; an emissions averaging approach which meets the requirements in § 129.107; a control system that will achieve a reduction in emissions equivalent to 0.8 lb VOC/lb solids for topcoats and 1.9 lb VOC/lb solids for sealers, as applied. The proposed emission limit for high solids topcoats is 1.8 lb VOC/lb solids, as applied and 1.9 lb VOC/lb solids, as applied for high solids sealers. An allowable emissions limit equal to 2.3 lb VOC/lb solids, as applied, is proposed for the use of acid-cured alkyd amino vinyl sealers. When using acid-cured alkyd amino conversion varnish topcoats, the VOC emissions limit is 2.0 lb VOC/lb solids, as applied. These proposed emission limits for sealers and topcoats are equivalent to coatings with a solids content of approximately 32 to 35% by weight.
§ 129.103. Work practice standards.
This section establishes work practice standards to reduce VOC emissions from wood furniture manufacturing operations. The proposed work practice standards include the development of a work practice implementation plan which includes an operator training program, leak inspection and maintenance plan, and a cleaning and washoff solvent accounting system. Subsection (a) requires the owner or operator of a facility subject to §§ 129.101--129.107 to develop and maintain a work practice implementation plan no later than 60 days after the compliance date. The work practice implementation plan must include an operator training program, leak inspection and maintenance plan, a cleaning and washoff solvent accounting system, spray booth cleaning requirements, storage requirements and application equipment requirements. The owner or operator of the wood furniture manufacturing facility must comply with each provision of the work practice implementation plan. If the Department determines that the work practice implementation plan does not adequately address the criteria specified in §§ 129.103(b)--(j), the owner or operator must revise the plan.
Subsection (b) describes the elements of the operator training program. A copy of the required operator training program must be maintained with the work practice implementation plan. All new and existing personnel, including contract personnel, who are involved in coating, cleaning or washoff operations or implementation of the requirements in §§ 129.101--129.107 must complete the operator training program. The proposal requires any new personnel hired after date of publication of the final rulemaking to be trained upon hiring. The operator training program must be completed within 6 months of the date of publication of the final rule by employes hired before the effective date of the rule.
Subsection (c) specifies the requirements for the proposed leak inspection and maintenance plan. The plan must address the required monthly visual inspections of equipment used to transfer or apply coatings or solvents and procedures for documenting the date and results of each inspection and any repairs that were made. The plan must also include procedures to address the detection and repair of leaks. At a minimum, an attempt to repair the leaks must begin no later than 5 working days after the leak is detected. Final repairs to the system must be made within 15 working days, unless new equipment is being installed to repair the system. When installing new equipment, repairs must be completed no later than 3 months from the date a leak is detected.
Subsection (d) describes the requirements pertaining to the cleaning and washoff solvent accounting system. A solvent accounting form must be developed for recording the following:
(1) The quantity and type of solvent used each month for washoff and cleaning.
(2) The number of pieces washed off and the reason for the washoff.
(3) The net quantity of spent solvent generated from each activity. The net quantity of spent solvent is equivalent to the total amount of solvent that is generated from the activity minus any solvent that is reused onsite for operations other than cleaning or washoff and any solvent that was sent offsite for disposal.
Subsection (e) specifies the work practices for spray booth cleaning. Unless a spray booth is being refurbished, the use of a strippable spray booth material with a VOC content no greater than 8.0% by weight of VOC is required for cleaning spray booth components other than conveyors, continuous coaters and their enclosures, or metal filters. If the spray booth is being refurbished, no more than 1 gallon of solvent may be used to prepare the booth prior to applying the booth coating.
Proposed § 129.103 also includes work practice standards for the storage of equipment, line cleaning, spray gun cleaning and washoff operations. Subsection (g) describes the work practice standards for application equipment and limits the use of conventional air spray guns. The use of conventional air spray guns is prohibited unless the air spray guns are used in accordance with the procedures in § 129.103(g)(1)--(6). Conventional air spray guns may be used to automatically apply coatings that have a VOC content less than or equal to 1.0 lb VOC/lb solids (1.0 kg VOC/kg solids), as applied. The use of air spray guns for touch-up and repair coatings is allowed if the coatings are applied after completion of the wood furniture manufacturing operation. The coatings must also be applied after the stain and before any other type of coating is applied and the coatings are applied from a container that has a volume of no more than 2.0 gallons. The proposed amendments also prohibit the use of conventional air spray guns if the cumulative total coating is more than 5.0% of the total gallons of coating used during a semiannual reporting period.
§ 129.104. Compliance procedures and monitoring requirements.
This section describes compliance procedures and monitoring requirements used to demonstrate compliance with the proposed presumptive RACT requirements for wood furniture manufacturing operations. The owner or operator of a facility subject to the emission standards of § 129.102 must demonstrate compliance through the use of compliant coatings, use of add-on control devices, an emissions averaging approach or a combination of the compliance methods. When a combination of compliance options are selected, the owner or operator must demonstrate compliance with each applicable compliance technique. When compliant coatings are being used, the owner or operator must maintain certified product data sheets for each coating. If a solvent or other VOC is added to the coating before application, the facility must account for the dilution and maintain documentation showing the VOC content of the coating as applied, in lb VOC/lb solids.
Subsection (b) describes the requirements for initial compliance. The owners or operators of a facility demonstrating compliance through the use of compliant coatings must submit an initial compliance status report in accordance with § 129.106(b). In accordance with subsection (b)(1), the initial compliance report must indicate that compliant sealers, topcoats and strippable spray booth coatings are being used by the facility.
Subsection (b)(2) explains the initial compliance requirements for facilities using a continuous coater to apply sealers, topcoats, or both. To demonstrate initial compliance, the owners or operators are required to submit an initial compliance status report which specifies that compliant sealers, topcoats or both, as determined by the VOC content of the coating in the reservoir and as calculated from records, are being used. The report must also specify that compliant sealers, topcoats, or both, as determined by the VOC content of the coating in the reservoir, are being used and the viscosity of the coating in the reservoir is being monitored. The data provided must show a correlation between the viscosity and the VOC content of the coating in the reservoir.
Subsection (b)(3) requires users of control systems to include the operating parameter values to be monitored for the capture device and the results of the initial performance testing in the initial compliance report. The procedures and test methods must meet the requirements specified in Chapter 139 (relating to sampling and testing).
Continuous compliance demonstrations.
The owners or operators of wood furniture manufacturing operations subject to the requirements of this proposal must submit a compliance certification with the semiannual report required under § 129.106(c). Facilities using compliant coatings to demonstrate compliance are required to maintain records that prove that the coatings are compliant. The compliance certification must also state that compliant sealers, topcoats, or both, and strippable spray booth coatings have been used each day in the semiannual reporting period.
Section 129.104(c)(2) explains the continuous compliance requirements for facilities using continuous coaters to apply sealers or topcoats. The compliance certification submitted to the Department must include a statement that compliant sealers, topcoats, or both, have been used each day in the semiannual reporting period. If the facility has not been in compliance continually, the certification must specify the days of noncompliance and the reasons for noncompliance.
Subsection (c)(3) specifies the requirement for facilities which demonstrate compliance by using a control system. Owners or operators of affected sources are required to install, calibrate, maintain and operate monitoring equipment that has been approved, in writing, by the Department. If the facility is using a control system that is not described in § 129.104, approval by the Department must be obtained prior to using the control system. The request for approval of the control system includes the following: a description of the system, test data verifying the performance of the system, the appropriate operating parameter values that will be monitored and the monitoring device that will be used to demonstrate continuous compliance with the standard.
The compliance certification for the control system must specify that the control system has not been operated at a daily average value greater than or less than (as appropriate) the operating parameter value for each day in the semiannual reporting period. If the control system exceeds the operating parameter values, the certification must identify the days of noncompliance and the reasons for noncompliance.
Each owner or operator of a facility subject to the work practice standards of § 129.103 shall demonstrate continuous compliance by following the work practice implementation plan and submitting a compliance certification which states that the work practice implementation plan is being followed, or should otherwise identify the periods of noncompliance with the work practice standards and the reasons for noncompliance.
Subsection (d) requires compliance certifications to be signed by a responsible official of the company. In addition to the certification requirements of this section, the responsible official must state that, based on information and belief formed after reasonable inquiry, the statements and information in the documents are true, accurate and complete.
§ 129.105. Recordkeeping requirements.
This section establishes recordkeeping requirements for wood furniture manufacturing operations. The owners or operators of affected facilities must keep records adequate to demonstrate compliance with §§ 129.101--129.107. The records shall be maintained for at least 5 years. This section also includes specific recordkeeping requirements for facilities using compliant coatings, continuous coaters and control systems. The recordkeeping requirements include the following:
(1) A certified product data sheet for each coating and strippable spray booth coating.
(2) Records of the VOC content as applied, lb VOC/lb solids (kg VOC/kg solids), of each coating and strippable spray booth coating and copies of data sheets documenting how the as-applied values were determined. Facilities applying sealers, topcoats, or both, using continuous coaters must also keep records of solvent and coating additions to the continuous coater reservoir and viscosity measurements.
Subsection (d) prescribes additional recordkeeping requirements for control systems which include copies of the calculations to support the equivalency of using a control system and records of the daily average value of each continuously monitored parameter for each operating day. If all recorded values for a monitored parameter are within the range established during the initial performance test, the owner or operator may record that all values were within the range rather than calculating and recording an average for that day.
Subsection (e) specifies that copies of the work practice implementation plan and all records associated with meeting the requirements of that plan must be maintained onsite. The records kept for the work practice implementation plan must satisfy the recordkeeping requirements for applicable provisions of the work practice implementation plan including the operator training program, the leak inspection and maintenance plan, cleaning and washoff solvent accounting system and restrictions on the use of conventional air spray guns.
§ 129.106. Reporting requirements.
This section establishes reporting requirements for wood furniture manufacturing operations subject to §§ 129.101--129.107. The owner or operator of a facility using a control system must submit an initial notification to the Department that meets the requirements of 40 CFR 63.9(b) (relating to notification regulations). This submittal notifies the Department that VOC emissions from the facility meet or exceed the applicability threshold for the presumptive RACT requirements for wood furniture manufacturing operations.
Subsection (b) requires owners or operators of affected facilities to submit an initial compliance report to the Department no later than 60 days after the compliance date. The report must include the items required by § 129.104(b).
Subsection (c) requires the submittal of semiannual reports certifying compliance for the previous 6 months of wood furniture manufacturing operations. The first report should be submitted to the Department within 30-calendar days after the end of the first 6-month period following the compliance date. Subsequent reports must be submitted within 30-calendar days after the end of each 6-month period following the first report.
§ 129.107. Special provisions for facilities using an emissions averaging approach.
This section allows the owners or operators of manufacturing operations to comply with the VOC emission limitations by averaging emissions across wood furniture finishing lines. The wood furniture manufacturing operation may use stains, basecoats, washcoats, sealers and topcoats in an emissions averaging program which meets the equivalency requirements in § 129.51(a). The facility may use other coatings for its emissions averaging program if the averaging approach meets the equivalency requirements. The averaging program submitted to the Department for approval prior to use must include a summary of the reasons why the facility would like to comply with the emission limitations through an equivalency determination using emissions averaging procedures. The program summary will also include an explanation of how averaging can be used to meet the emission limitations and a description of the types of coatings that will be included in the facility's emissions averaging program. An additional 10% reduction in emissions is required under subsection (b) for affected facilities using an emissions averaging approach.
Subsection (e) specifies that the baseline for each coating included in the emissions averaging program shall be the lower of the actual or allowable emission rate as of the effective date of this proposal. The baseline emission rate for the facility cannot be higher than what was presumed in the 1990 emissions inventory for the facility unless the Department has accounted for the increase in emissions as growth.
Subsection (f) provides that the quantification procedures used in the emissions averaging program must demonstrate that the facility's actual emissions are less than the allowable emissions.
Subsection (g) requires that the written summary of the emissions averaging program submitted to the Department include monitoring, recordkeeping and reporting procedures that will allow Department inspectors and owners or operators of facilities using an averaging approach to determine the facility's compliance status on a daily basis. The monitoring, recordkeeping and reporting procedures must also include methods for determining required data when monitoring, recordkeeping and reporting violations result in missing, inadequate or erroneous monitoring and recordkeeping.
Chapter 139. Sampling and Testing
Subchapter A. Sampling and Testing
Methods and Procedures
§ 139.4. References.
The proposed revisions to this section reflect name changes for the Department and the Bureau of Air Quality.
§ 139.14. Emissions of VOCs.
The proposed amendments to this section require that the test methods and procedures for the content of total volatiles, solids, exempt solvents and water and the coating density be equivalent to those listed in § 139.4(1) and (5).
F. Benefits and Costs
Executive Order 1996-1 requires a cost/benefit analysis of the proposed amendments.
Compliance with the proposed amendments will reduce VOC emissions to the atmosphere. Implementation of the proposed work practice standards will reduce emissions from cleaning operations. The restrictions on the use of conventional air spray guns will result in less overspraying and will therefore reduce the amount of solid waste generated from overspraying. Emission reductions resulting from this proposal are also expected to reduce worker exposure to VOC emissions and other pollutants.
The proposed amendments will affect approximately 450 surface coating facilities, including 80 wood furniture manufacturing facilities, which are currently subject to recordkeeping and reporting requirements. Approximately 20 of the major wood furniture manufacturing operations that would be subject to this proposal have submitted case-by-case RACT determinations to the EPA for approval as SIP revisions. The EPA has indicated that case-by-case RACT determinations for wood furniture manufacturing operations must, at a minimum, meet the requirements of the CTG for wood furniture manufacturing operations to be approvable as a SIP revision. Consequently, these provisions should be approved by the EPA as a SIP revision prior to the adoption of this proposal as a final rulemaking.
The proposed amendments to § 129.52 will result in estimated savings of $5,625,000 for approximately 450 affected facilities. These cost savings are based on a reduction of .25 FTE per facility per year in recordkeeping and reporting efforts, at an average salary of $50,000 for a total of $5,625,000 for the current fiscal year.
Compliance Assistance Plan
Compliance assistance will be provided to affected facilities that are engaged in surface coating processes or the manufacture of wood furniture or wood furniture components. The Department will utilize the Pennsylvania Small Business Assistance Program and its ongoing regional compliance assistance program to assist small businesses in understanding and complying with the proposed regulations in Chapter 129.
The proposed work practice standards for the wood furniture manufacturing industry will reduce VOC emissions from affected sources. The proposed restrictions on the use of conventional air spray guns will reduce the amount of VOCs emitted and the amount of solid waste generated from wood finishing operations. In addition, the implementation of operator training programs will also reduce emissions and prevent pollution from wood finishing, clean-up and washoff operations.
These proposed amendments contain recordkeeping and reporting provisions needed to demonstrate compliance with the requirements of the proposed surface coating and wood furniture manufacturing requirements. The owner or operator of an affected facility which complies with the wood furniture manufacturing provisions in §§ 129.101--129.107 must prepare and maintain a work practice implementation plan including work practices for operator training, leak inspection and maintenance planning and cleaning and washoff solvent accounting. The owners or operators of affected facilities must also prepare and maintain records of work practice plan activities, use of compliant coatings or an alternative methodology. The facilities must also validate and verify information used to demonstrate compliance and prepare and maintain compliance certification records. However, the paperwork requirements will vary for facilities using compliant coatings, add-on air pollution control equipment or an emissions averaging approach to demonstrate compliance with the presumptive RACT requirements.
Any wood furniture manufacturing facility complying with the case-by-case RACT determinations or the National Emission Standards for Hazardous Air Pollutants (NESHAP) will have the same work practice standards and application equipment requirements. The Board expects that the majority of the remaining 60 wood furniture manufacturing facilities will be subject to the NESHAP for wood furniture manufacturing operations in 40 CFR Part 63 Subpart JJ (relating to National emission standards for wood furniture manufacturing operations). These facilities will already have developed and implemented the paperwork requirements associated with the work practice standards such as operator training, inspection and maintenance planning, cleaning and washoff solvent accounting prior to the effective date of the final rulemaking.
G. Sunset Review
This proposed rulemaking will be reviewed in accordance with the sunset review schedule published by the Department to determine whether the regulations effectively fulfill the goals for which they were intended.
H. Regulatory Review
Under section 5(a) of the Regulatory Review Act (71 P. S. § 745.5(a)), on February 17, 1999, the Department submitted a copy of the proposed rulemaking to the Independent Regulatory Review Commission (IRRC) and to the Chairpersons of the Senate and House Environmental Resources and Energy Committees. In addition to submitting the proposed amendments, the Department has provided IRRC and the Committees with a copy of a detailed regulatory analysis form prepared by the Department. A copy of this material is available to the public upon request.
If IRRC has objections to any portion of the proposed amendments, it will notify the Department within 10 days of the close of the Committees' review period. The notification shall specify the regulatory review criteria which have not been met by that portion. The Regulatory Review Act specifies detailed procedures for the Department, the Governor and the General Assembly to review these objections before final publication of the regulations.
I. Public Comments
Written Comments--Interested persons are invited to submit comments, suggestions or objections regarding the proposed amendments to the Environmental Quality Board, P. O. Box 8477, Harrisburg, PA 17105-8477 (express mail: Rachel Carson State Office Building, 15th Floor, 400 Market Street, Harrisburg, PA 17105-8477). Comments submitted by facsimile will not be accepted. Comments, suggestions or objections must be received by the Board by May 10, 1999. Interested persons may also submit a summary of their comments to the Board. The summary may not exceed one page in length and must also be received by May 10, 1999. The one-page summary will be provided to each member of the Board in the agenda packet distributed prior to the meeting at which the final-form regulations will be considered.
Electronic Comments--Comments may be submitted electronically to the Board at RegComments@ dep.state.pa.us. A subject heading of the proposal and return name and address must be included in each transmission. Comments submitted electronically must also be received by the Board by May 10, 1999.
J. Public Hearings
The Board will hold four public hearings for the purpose of accepting comments on this proposal. The hearings will be held at 10 a.m. as follows:
April 6, 1999 Department of Environmental
Southwest Regional Office
400 Waterfront Drive
April 7, 1999 Department of Environmental
Southcentral Regional Office
Susquehanna River Conference Room
909 Elmerton Avenue
April 8, 1999 Department of Environmental
Southeast Regional Office
Suite 6010, Lee Park
555 North Lane
April 9, 1999 Department of Environmental
Northcentral Regional Office
208 W. Third Street
The Department is specifically requesting comments on the following issues:
(1) Whether the Department should require the owners or operators of wood furniture manufacturing facilities with actual emissions or a potential to emit 25 tons per year or more of VOC emissions to comply with both the surface coating requirements in § 129.52 and the proposed presumptive RACT requirements in §§ 129.101--129.107.
(2) Whether the Department should adopt the reporting requirements in 40 CFR 63.7--63.10. These general reporting provisions specify time frames for reporting performance test results, monitoring parameter values and excess performance test results. The EPA's model rule for wood furniture manufacturing operations provides the general MACT reporting requirements as an optional State presumptive RACT program component.
Persons wishing to present testimony at a hearing are requested to contact Kate Coleman at the Environmental Quality Board, P. O. Box 8477, Harrisburg, PA 17105-8477, (717) 787-4526, at least 1 week in advance of the hearing to reserve a time to present testimony. Oral testimony is limited to 10 minutes for each witness. Witnesses are requested to submit three written copies of their oral testimony to the hearing chairperson at the hearing. Organizations are limited to designating one witness to present testimony on its behalf at each hearing.
Persons with a disability who wish to attend a hearing and require an auxiliary aid, service or other accommodation to participate should contact Kate Coleman at (717) 787-4526, or through the Pennsylvania AT&T Relay Service at (800) 654-5984 (TDD) to discuss how the Department may accommodate their needs.
