Any Coating, Coating operation, or facility which is exempt from all or a portion of the VOC limits of this Rule shall comply with the provisions of

Rule 417.Imperial County Air Pollutio n Control District Rule 427

427

- 17 F. Construction of Headings Monitoring and Records

Section and subsection headings do not in any manner affect the scope, meaning, or intent of the provisions of this Rule.

All Persons subject to this Rule and any Person cl aiming any exemption under subsection D.1 shall comply with the following requirements:

F.1 Maintain and have available during an inspection, a current list of Coating in use which provides all of the Coating data necessary to evaluate compliance, includi ng the following information separately for both Group I and II vehicles , as applicable:

F.1.a Additive, Coating, Catalyst, and Reducer used.

F.1.b Mix ratio of components used

F.1.c VOC content of Coating as applied.

F.2 Maintain records on a daily basis including:

F.2.a Coating and mix ratio of components used in the Coating; and

F.2.b quantity of each Coating applied.

F.2.c Any Person/facility utilizing an add

- on emission Control Device/system as a means of complying with provisions of this Rule shall also maintain records of key system operating and maintenance data for the purpose of demonstrating continuous compliance during periods of emission producing activities. The data shall be recorded in a manner a prescribed by the District.

F.3 The Person shall maintain records on a monthly basis showing the type and amount of solvent used for cleanup and surface preparation.

F.4 Such records shall be retained and available for inspection by the Air Pollution Control Officer for the previous 24 month period.

G. Severability Test Methods

Each part of this Rule shall be deemed severable, and in the event that any part
of this Rule is held to be invalid, the remainder of the Rule shall continue in full

force and effect.

G.1 A violation of the limits contained in this Rule as determined by any one ofImperial County Air Pollutio n Control District Rule 427

427

- 18 these test methods shall constitute a violation of this Rule.

G.2 The following specified test methods sha ll be used to determine compliance with the provisions of this Rule.

G.2.a Analysis of Samples

- VOC Determination:

Samples of Volatile Organic Compounds (less Exempt Compounds) as specified in Sections C.1.a.1 to C.1.a.2 shall be analyzed as prescribed by EPA Reference Method 24 for VOC content (without correction for Exempt Compounds) and ASTM

Test Method D4457

- 85, or CARB Method 432 for determination of emissions of Exempt Compounds. Perfluorocarbon compounds shall be assumed to be absent from a product or process unless a manufacturer or facility operator identifies the specific individual compounds (from the broad classes of perfluorocarbon compounds) and the amount present in the product or process and provides a validated test method which can be used to quantify the specific compounds.

G.2.b Determination of Emissions:

Emissions of Volatile Organic Compounds as specified in Sections C.1.a.1 or C.1.a.2 shall be measured as prescribed by EPA Reference Method 25 for determining VOC emissions and Control Device efficiency, in combination with the methods prescribed in U.S. EPA document Guidelines for Determining Capture Efficiency, dated January 9, 1995.

G.2.c Determination of Transfer Efficiency:

Transfer Efficiency as required by Section C.2.a.3 shall be determined by procedures as prescribed in the SCAQMD document "South Coast Air Quality Management Distric t Spray Equipment Transfer Efficiency Test Procedure for Equipment User, May 24,

1998".

G.2.d Determination of Percentage of Metal in Metallic Coatings:

Determinations shall be made using SCAQMD Method 311

- 91,

"Determination of Percent Metal in Metalli c Coatings by Spectrographic Method", as found in the SCAQMD document Laboratory Methods Of Analysis For Enforcement Samples, The

June 1991 edition.

G.2.e Acidity in volatile Solvents and in Coating Compounds:Imperial County Air Pollutio n Control District Rule 427

427

- 19 Determination of acid strength shall be ma de using ASTM Test

method D1613

- 85.

G.2.f Determination of Exempt Compounds Content:

Determination of the content of Exempt Compounds in Coating or solvents or any diluents shall be by ASTM Test Method D4457

- 85.
