F.1.e. If at any time a pe rson uses coatings or materials exceeding the VOC limits specified in Sections D.2, D.3, and D.4 of this rule, records shall be maintained on a daily basis showing the type and volume of materials used.

F.1.f. For persons using a collection and control system pursuant to Section D.5 of this rule, records shall be maintained on a daily basis showing the type and volume of coatings and solvents used.FEATHER RIVER AQMD REGULATION III - 16 F.1.g. Any person using an emission control system pursuant to the provisions of Section D.5 as a means of compliance with this rule shall maintain daily records of key system operating and maintenance procedures which will demonstrate continuous operation and compliance of the emission control device during periods of emission-producing activities. Key system operating parameters are those necessary to ensure compliance with the requirements of
Section D.5 of this rule.

F.2. Duration of Records: All records required by this rule shall be maintained for at least three (3) years, and shall be made available to the Air Pollution Control Officer upon
request.

F.3. Test Methods:

F.3.a. Determination of VOC Content: VOC content of wood products coatings, strippers, and surface preparation and cleanup materials subject to this
rule shall be determined in accordance with EPA Method 24 and Section E.3 or E.4 of this rule, as applicable.

F.3.b. Determination of Composition of VOC: The composition of VOC shall be as specified on the manufacturer’s label or data sheet, or as determined by ASTM Method E-260, General Gas Chromatograph.

F.3.c. Determination of Compounds Exempt from VOC Definition: Compounds exempted from VOC definition, as listed in Section C. of this rule,
shall be determined in accordance with South Coast Air Quality Management District Method 303. If any of the perfluorocarbons or volatile cyclic and linear methyl siloxanes are being claimed as exempt compounds, the person making the claim must state in advance which compounds are present, and the EPA approved test method used to make the determination of these compounds.

F.3.d. Determination of Capture Efficiency: Efficiency of the collection system shall be determined in accordance with EPA “Guidelines for Determining Capture Efficiency, January 9, 1995”. Individual collection efficiency test runs subject to the U.S. EPA technical guidelines shall be determined by:FEATHER RIVER AQMD REGULATION III - 17 F.3.d.1. Applicable U.S. EPA Methods 204, 204A, 204B, 204C, 204E, and/or, 204F.
F.3.d.2. The South Coast Air Quality Management
District “Protocol for Determination of Volatile Organic Compound (VOC) Capture Efficiency”; or

F.3.d.3. Any other method approved by the U.S. EPA, the California Air Resources Board, and the Air Pollution Control
Officer.

F.3.e. Determination of Control Efficiency: Efficiency of control equipment shall be determined in accordance with EPA Method 18, 25, 25A, EPA Method 2 or 2C (whichever is applicable).

F.3.f. Vapor Pressure: Vapor pressures may be obtained from standard reference texts or may be determined by ASTM D-2879. F.3.g. Volatile Content of Radiation Curable Materials:
Volatile content of radiation curable materials
shall be obtained in accordance with ASTM Method

D-5403-93.
