Current through Register Vol. 49, No. 21, November 1, 2024.

Section 10 CSR 10-5.530 - Control of Volatile Organic Compound Emissions From Wood Furniture Manufacturing Operations

PURPOSE: This rule limits the volatile organic compound (VOC) emissions from wood furniture manufacturing operations by incorporating reasonably available control technology (RACT) per 172(c)(1) of the Clean Air Act.

(1) Applicability.

(A) This rule applies throughout the City of St. Louis and St. Charles, St. Louis, Jefferson, and Franklin Counties.

(B) This rule is applicable to all existing wood furniture manufacturing installations that have the potential to emit equal to or greater than twenty-five (25) tons per year of volatile organic compounds (VOC).

(C) Adhesives shall not be considered coatings or finishing materials for the purposes of this rule.

(D) In the event that other rules in Title 10 Division 10 of the Code of State Regulations are also applicable to wood furniture manufacturing installations, the more stringent rule applies.

(2) Definitions.

(A) Adhesive-Any chemical substance applied for bonding two (2) surfaces together other than by mechanical means.

(B) Affected source-A wood furniture manufacturing facility that meets the criteria listed in subsections (1)(A) and (1)(B) of this rule.

(C) Alternative method-Any method of sampling and analyzing for an air pollutant that is not a reference or equivalent method but that has been demonstrated to the director's satisfaction to, in specific cases, produce results adequate for a determination of compliance.

(D) As applied-The VOC and solids content of the finishing material that is actually used for coating the substrate. It includes the contribution of materials used for in-house dilution of the finishing material.

(E) Basecoat-A coat of colored material, usually opaque, applied before graining inks, glazing coats, or other opaque finishing materials and is usually top coated for protection.

(F) Capture device-A hood, enclosed room, floor sweep, or other means of collecting solvent emissions or other pollutants into a duct so that the pollutant can be directed to a pollution control device such as an incinerator or carbon adsorber.

(G) Capture efficiency-The fraction of all organic vapors generated by a process that is directed to a control device.

(H) Certified product data sheet- Documentation furnished by a coating supplier or an outside laboratory that provides the VOC content by percent weight, the solids content by percent weight, and density of a finishing material, strippable booth coating, or solvent, measured using the EPA Method 24, or an equivalent or alternative method (or formulation data if approved by the director). The purpose of the certified product data sheet is to assist the affected source in demonstrating compliance with the emission limitations presented in subsection (3)(A) of this rule. Therefore, the VOC content should represent the maximum VOC emission potential of the finishing material, strippable booth coating, or solvent.

(I) Cleaning operations-Operations in which organic solvent is used to remove coating materials from equipment used in wood furniture manufacturing operations.

(J) Coating-A protective, decorative, or functional material applied in a thin layer to a surface. Such materials include, but are not limited to, paints, topcoats, varnishes, sealers, stains, washcoats, basecoats, inks, and temporary protective coatings.

(K) Coating solids (or "solids")- The part of the coating that remains after the coating is dried or cured; solids content is determined using data from EPA Method 24, or an alternative or equivalent method.

(L) Compliant coating-A finishing material or strippable booth coating that meets the emission limits specified in paragraph (3)(A)1. of this rule.

(M) Continuous coater-A finishing system that continuously applies finishing materials onto furniture parts moving along a conveyor system. Finishing materials that are not transferred to the part are recycled to the finishing material reservoir. Several types of application methods may be used with a continuous coater including spraying, curtain coating, roll coating, dip coating, and flow coating.

(N) Control device-Any equipment that reduces the quantity of a pollutant that is emitted to the air. The device may destroy or secure the pollutant for subsequent recovery. Includes, but is not limited to, incinerators, carbon adsorbers, and condensers.

(O) Control device efficiency-The ratio of the pollution released by a control device and the pollution introduced to the control device, expressed as a fraction.

(P) Control system-The combination of capture and control devices used to reduce emissions to the atmosphere.

(Q) Conventional air spray-A spray coating method in which the coating is atomized by mixing it with compressed air at an air pressure greater than ten (10) pounds per square inch (gauge) at the point of atomization. Airless and air assisted airless spray technologies are not conventional air spray because the coating is not atomized by mixing it with compressed air. Electrostatic spray technology is also not considered conventional air spray because an electrostatic charge is employed to attract the coating to the work-piece.

(R) Day-A period of twenty-four (24) consecutive hours beginning at midnight local time, or beginning at a time consistent with a facility's operating schedule.

(S) Disposed off-site-Sending used organic solvents or coatings outside of the facility boundaries for disposal.

(T) Emission-The release or discharge, whether directly or indirectly, of VOC into the ambient air.

(U) Equipment leak-Emissions of volatile organic compounds from pumps, valves, flanges, or other equipment used to transfer or apply finishing materials or organic solvents.

(V) Equivalent method-Any method of sampling and analyzing for an air pollutant that has been demonstrated to the director's satisfaction to have a consistent and quantitatively known relationship to the reference method under specific conditions.

(W) Finishing application station-The part of a finishing operation where the finishing material is applied, e.g., a spray booth.

(X) Finishing material-Coatings used in the wood furniture industry including, but not limited to, basecoats, stains, washcoats, sealers, and topcoats.

(Y) Finishing operation-Those activities in which a finishing material is applied to a substrate and is subsequently air-dried, cured in an oven, or cured by radiation.

(Z) Incinerator-An enclosed combustion device that thermally oxidizes volatile organic compounds to carbon monoxide (CO) and carbon dioxide (CO₂). This term does not include devices that burn municipal or hazardous waste material.

(AA) Nonpermanent final finish-A material such as a wax, polish, nonoxidizing oil, or similar substance that must be reapplied periodically to a surface over its lifetime to maintain or restore the material's intended effect.

(BB) Normally closed container-A storage container that is closed unless an operator is actively engaged in activities such as emptying or filling the container.

(CC) Operating parameter value-A minimum or maximum value established for a control device or process parameter that, if achieved by itself or in combination with one or more other operating parameter values, determines that an owner or operator has complied with an applicable emission limit.

(DD) Organic solvent-A liquid containing volatile organic compounds used for dissolving or dispersing constituents in a coating, adjusting the viscosity of a coating, cleaning, or washoff. When used in a coating, the organic solvent evaporates during drying and does not become a part of the dried film.

(EE) Overall control efficiency-The efficiency of a control system, calculated as the product of the capture and control device efficiencies, expressed as a percentage.

(FF) Recycled on-site-The reuse of an organic solvent in a process other than cleaning or washoff.

(GG) Reference method-Any method of sampling and analyzing for an air pollutant that is published in Appendix A of 40 CFR 60.

(HH) Sealer-A finishing material used to seal the pores of a wood substrate before additional coats of finishing material are applied. Washcoats, which are used in some finishing systems to optimize aesthetics, are not sealers.

(II) Stain-Any color coat having a solids content by weight of no more than 8.0 percent that is applied in single or multiple coats directly to the substrate. Includes, but is not limited to, nongrain raising stains, equalizer stains, sap stains, body stains, no-wipe stains, penetrating stains, and toners.

2) that is subsequently peeled off and disposed; and

3) by achieving 1) and 2), reduces or eliminates the need to use organic solvents to clean booth walls.

(LL) Substrate-The surface onto which coatings are applied (or into which coatings are impregnated).

(MM) Topcoat-The last film-building finishing material applied in a finishing system. Nonpermanent final finishes are not topcoats.

(NN) Touch-up and repair-The application of finishing materials to cover minor finishing imperfections.

(OO) Washcoat-A transparent special purpose coating having a solids content by weight of 12.0 percent or less. Washcoats are applied over initial stains to protect and control color and to stiffen the wood fibers in order to aid sanding.

(PP) Washoff operations-Those operations in which organic solvent is used to remove coating from a substrate.

(QQ) Wood furniture-Any product made of wood, a wood product such as rattan or wicker, or an engineered wood product such as particleboard that is manufactured under any of the following standard industrial classification codes: 2434, 2511, 2512, 2517, 2519, 2521, 2531, 2541, 2599 or 5712.

2. As an alternate to the finishing operation requirements of paragraph (3)(A)1. of this rule, the owner or operator of an affected source may use an averaging approach to verify compliance by using this paragraph. Compliance is demonstrated when actual emissions from the affected source are less than or equal to allowable emissions using one (1) of the following inequalities:

Click to view image

where:

TC_i =kilograms of solids of topcoat "i" used;

SE_i =kilograms of solids of sealer "i" used;

WC _i =kilograms of solids of washcoat "i" used;

BC_i =kilograms of solids of basecoat "i" used;

ST_i =liters of stain "i" used;

ER_TCi =VOC content of topcoat "i" in kg VOC/kg solids, as applied;

ER_SEi =VOC content of sealer "i" in kg VOC/kg solids, as applied;

ER_WCi =VOC content of washcoat "i" in kg VOC/kg solids, as applied;

ER_BCi =VOC content of basecoat "i" in kg VOC/kg solids, as applied; and

ER_STi =VOC content of stain "i" in kg VOC/liter (kg/l), as applied.

Note 1: Various numeric values used in inequalities (0.8, 1.8, 1.9, etc.) are maximum allowable VOC contents for various coatings.

Note 2: The 0.9 multiplying factor on the allowable emissions side of the inequality is used to assure that sources using the averaging approach demonstrate their emissions are no greater than ninety percent (90%) of what they would be if they were using compliant coatings.

For Inequalities (1) and (2), the facility must use the actual VOC content of the finishing materials used prior to the effective date of this rule if the VOC content is less than the allowable VOC content. For example, if the affected source was using topcoats with a VOC content of 1.7 kilograms of VOC per kilogram of solids (1.7 pounds of VOC per pound of solids) before being subject to this rule, the affected source must use that value in Inequality (2) rather than 1.8.

3. As an alternate to the finishing operation requirements of subparagraph (3)(A)1.A. or part (3)(A)1.B.(II) of this rule, the owner or operator of an affected source may use a control system (capture device/control device) that will achieve an equivalent reduction in emissions as demonstrated using the compliance requirements of subparagraph (3)(C)1.B. of this rule.

4. As an alternate to the finishing operation requirements of paragraphs (3)(A)1. and (3)(A)2. of this rule, the owner or operator of an affected source may use a combination of the methods presented in paragraphs (3)(A)1., (3)(A)2., and (3)(A)3. of this rule as demonstrated using the compliance requirements of subparagraph (3)(C)1.C. of this rule.

5. The owner or operator of an affected source shall limit VOC emissions from cleaning operations when using a strippable booth coating to that shown in Table 6.

Table 6

kg VOC/kg solids (as applied)	lb VOC/lb solids (as applied)
Strippable booth coating	0.8	0.8

3. Program baseline. The baseline for each finishing material included in the averaging program shall be the lower of the actual or allowable emission rate as of the effective date of this rule;

4. Quantification procedures. The owner or operator of the affected source shall specify methods and procedures for quantifying emissions. Quantification procedures for VOC content are included in section (5) of this rule. The owner or operator shall specify methods to be used for determining the usage of each finishing material. The quantification methods used shall be accurate enough to ensure that the affected source's actual emissions are less than the allowable emissions, as calculated using Inequality (1) or (2) in paragraph (3)(A)2. of this rule, on a daily basis to a level of certainty comparable to that for traditional control strategies applicable to surface coating sources;

5. Monitoring, record keeping, and reporting. The owner or operator of an affected source shall provide a summary of the monitoring, record keeping, and reporting procedures that will be used to demonstrate daily compliance with the inequalities presented in paragraph (3)(A)2. of this rule. The monitoring, record keeping, and reporting procedures shall be structured in such a way that inspectors and facility owners can determine an affected source's compliance status for any day. Furthermore, the procedures shall include methods for determining required data when monitoring, record keeping, and reporting violations result in missing, inadequate, or erroneous monitoring and record keeping. These procedures must ensure that sources have sufficiently strong incentive to properly perform monitoring and record keeping;

6. Implementation schedule. The owner or operator of an affected source shall submit an averaging proposal for state and EPA approval by July 31, 2001; and

7. Administrative procedures. Any affected source may submit an averaging approach proposal to the director for consideration in meeting the compliance requirements of this rule. The director shall take the following actions:

F. Copies of logs and other documentation developed to demonstrate that the other provisions of the work practice implementation plan are followed.

4. In addition to the records required by paragraph (4)(B)1. of this rule, the owner or operator of an affected source that complies through the method established in subparagraph (3)(C)1.A. or by demonstrating compliance with subsection (3)(A) of this rule shall maintain a copy of the compliance certifications submitted in accordance with paragraph (4)(A)3. of this rule for each semiannual period following the compliance date.

5. The owner or operator of an affected source shall maintain a copy of all other information submitted with the initial status report required by paragraph (4)(A)2. of this rule and the semiannual reports required by paragraph (4)(A)3. of this rule.

6. The owner or operator of an affected source shall maintain all records for a minimum of five (5) years.

7. Failure to maintain the records required by paragraphs (4)(B)1. through (4)(B)6. of this rule constitutes a violation of the rule for each day records are not maintained.

(5) Test Methods.

(A) The VOC content and the solids content by weight of the as-supplied finishing materials shall be determined by Method 24 as specified in 10 CSR 10-6.030(22). The owner or operator of the affected source may request approval from the director to use an alternative or equivalent method for determining the VOC content of the finishing material.

(B) Owners or operators demonstrating compliance with the provisions of this rule via a control system shall determine the overall control efficiency of the control system (R) as the product of the capture and control device efficiencies, using the test methods cited in subsection (5)(C) of this rule and the procedure in subsection (5)(D) of this rule.

(C) Owners or operators using a control system have to demonstrate initial compliance using the following 40 CFR 60 methods as incorporated by reference in 10 CSR 10-6.030(22).

1. The VOC concentration of gaseous air streams shall be determined with a test consisting of three (3) separate runs, each lasting a minimum of thirty (30) minutes using one (1) of the following reference methods:

A. Method 18;

B. Method 25; or

C. Method 25A.

2. Sample and velocity traverses shall be determined by using one (1) of the following reference methods:

A. Method 1- Sample and Velocity Traverses for Stationary Sources; or

B. Method 1A.

3. Velocity and volumetric flow rates shall be determined by using one (1) of the following reference methods:

A. Method 2; or

B. Method 2A;

C. Method 2C;

D. Method 2D;

E. Method 2F;

F. Method 2G; or

G. Method 2H.

4. To analyze the exhaust gases, use Method 3.

5. To measure the moisture in the stack gas, use Method 4.

(D) Owners or operators using a control system to demonstrate compliance with this rule shall determine capture efficiencies by using test methods stated in 10 CSR 10-6.030(20).
