Section 250-RICR-120-05-35.12 - Performance Test Methods35.12.1VOC and Solids ContentA. VOC and solids content, by weight, of coatings shall be demonstrated with 40 C.F.R. § 60 Appendix A-7 Method 24, incorporated in § 35.4(A) of this Part, or an alternative procedure approved by EPA and the Department. Sampling procedures shall follow the guidelines presented in "Standard Procedures for Collection of Coating and Ink Samples for VOC Content Analysis by Reference Method 24 and Reference Method 24A," EPA-340/ 1-91-010, incorporated in § 35.4(B) of this Part.B. The owner or operator of a facility that uses a finishing material that does not release VOC reaction byproducts during the cure; for example, if all VOC is solvent; may request permission to use batch formulation information to demonstrate compliance. If the VOC content of a coating determined by 40 C.F.R. § 60 Appendix A-7 Method 24, incorporated in § 35.4(A) of this Part, test is greater than that indicated by the facility's formulation data, the 40 C.F.R. § 60 Appendix A-7 Method 24 test shall govern.35.12.2VHAP and Solids ContentA.40 C.F.R. § 63 Appendix A Method 311 incorporated in § 35.4(A) of this Part, or an alternative method, if approved by EPA and the Department, shall be used in conjunction with formulation data to determine the VHAP content of the liquid coating. Formulation data shall be used to identify VHAP present in the coating, and Method 311 or an approved alternative method shall be used to quantify the VHAP identified through the formulation data. 40 C.F.R. § 63 Appendix A Method 311 shall not be used to quantify VHAP such as styrene and formaldehyde that are emitted during the cure.B.40 C.F.R. § 60 Appendix A-7 Method 24, incorporated in § 35.4(A) of this Part, shall be used to determine the solids content by weight and the density of coatings for the purpose of showing compliance with VHAP emission limitations.C. The owner or operator of a facility that uses a finishing material that does not release VOC or VHAP byproducts during the cure; for example, if all VOC and VHAP present in the coating is solvent; may request permission to use batch formulation information to demonstrate compliance.D. If the VOC content of a coating as determined by 40 C.F.R. § 60 Appendix A-7 Method 24 or 40 C.F.R. § 63 Appendix A Method 311, incorporated in § 35.4(A) of this Part test is higher than that indicated by a facility's formulation data, the 40 C.F.R. § 60 Appendix A-7 Method 24 or 40 C.F.R. § 63 Appendix A311 test shall govern, unless the facility can demonstrate to the satisfaction of the Department that formulation data are correct.E. Sampling procedures shall follow the guidelines presented in "Standard Procedures for Collection of Coating and Ink Samples for VOC Content Analysis by Reference Method 24 and Reference Method 24A," EPA-340/ 1-91-010, incorporated in § 35.4(B) of this Part.35.12.3Control Equipment EfficiencyA.40 C.F.R. § 60 Appendix A Methods 18, 25, or 25A, incorporated in § 35.4(A) of this Part, shall be used to determine the VOC concentration of gaseous air streams. EPA Method 18 shall be used to determine the VHAP concentration of gaseous air streams. The test shall consist of three (3) separate runs, each lasting a minimum of thirty (30) minutes.B.40 C.F.R. § 60 Appendix A-1Method 1 or 1A, incorporated in § 35.4(A) of this Part, shall be used for sample and velocity traverses.C.40 C.F.R. § 60 Appendix A-1 Method 2, 2A, 2C, or 2D, incorporated in § 35.4(A) of this Part, shall be used to measure velocity and volumetric flow rates.D.40 C.F.R. § 60 Appendix A-2 Method 3, incorporated in § 35.4(A) of this Part, shall be used to analyze exhaust gases.E.40 C.F.R. § 60 Appendix A-3 Method 4, incorporated in § 35.4(A) of this Part, shall be used to measure the moisture content of stack gas when required.F.40 C.F.R. § 60 Appendix A Methods 2, 2A, 2C, 2D, 3, and 4, incorporated in § 35.4(A) of this Part shall be performed, as applicable, at least twice during each test run.G. VOC and VHAP control systems must be constructed so that volumetric flow rates and VOC and/or total VHAP concentrations, as applicable, can be determined by the test methods specified in §§35.12.3(A) through (F) of this Part, as applicable.H. Capture efficiency shall be measured using measures approved by the EPA.I. Testing shall be performed while all affected emission points are connected and operating at maximum production rate.J. The efficiency §35.12.3(F) of this Part of the control device shall be determined using Equation 7 in §35.12.3(J) of this Part: Click here to view image
K. Determine the efficiency (N) of the capture system using Equation 8 in §35.12.3(K) of this Part: Click here to view image
L. If all effected emissions points are surrounded by a permanent enclosure that is demonstrated to be total by procedures acceptable to the Department and the EPA, the control device capture efficiency, N, is equal to 1250 R.I. Code R. 250-RICR-120-05-35.12
