100 GENERAL

101 PURPOSE: To limit emissions of volatile organic compounds from can coating operations. Coating operations subject to this Rule shall be exempt from the requirements of Rule 441.

200 DEFINITIONS

201 COATING LINE: An operation or process for applying, drying, baking and/or curing surface coatings, together with associated equipment including a coating applicator, flash-off area and oven.

202 CAN COATING: A coating applied or intended for application by spray, roller, or other means onto the interior and/or exterior surfaces of formed metal cans, or to the surface of flat metal sheets, strips, rolls, or coils intended for can construction.

203 END SEALING COMPOUND: A coating applied to can ends and which functions as a gasket when the end is assembled onto the can.

204 EXEMPT COMPOUND: For the purposes of this rule, "exempt compound" has the same meaning as in Rule 101—GENERAL PROVISIONS AND DEFINITIONS.

205 EXTERIOR BASE COATING: A coating applied to the exterior of a can to provide protection to the metal or to provide background for any lithographic or printing operation.

206 INTERIOR BASE COATING: A coating applied to the interior of a can to provide a protective lining between the product and the can.

207 INTERIOR BODY SPRAY: A coating sprayed on the interior of the can body to provide a protective lining between the product and the can.

208 OVERVARNISH: A coating applied directly over a design coating to reduce the coefficient of friction, to provide gloss and to protect the finish against abrasion and corrosion.

209 THREE-PIECE CAN SIDE-SEAM SPRAY: A coating sprayed on the interior and/or exterior of a welded, cemented or soldered seam to protect the exposed metal.

210 TWO-PIECE CAN EXTERIOR END COATING: A coating applied to the exterior end of a can to provide protection to the metal.

211 VOLATILE ORGANIC COMPOUND (VOC): For the purposes of this rule, "volatile organic compound" has the same meaning as in Rule 101—GENERAL PROVISIONS AND DEFINITIONS.

300 STANDARDS

301 VOC LIMITATION: Except as provided in Section 302, a person shall not use or apply any coating on any coating line of the type designated below which contain volatile organic compounds in excess of the following limits:

303 SOLVENT USAGE: Any person using solvents after December 1, 1990:

400 ADMINISTRATIVE REQUIREMENTS

401 OPERATION AND MAINTENANCE PLAN: Any facility using an emission control device as a means of complying with this rule, as provided in Section 302, must submit with the application for Authority to Construct and resubmit annually, upon completion of construction of the emission control device, an Operation and Maintenance Plan for the emission control device to the Air Pollution Control Officer for approval. The Plan shall specify operation and maintenance procedures which will demonstrate continuous operation of the emission control device during periods of emissions-producing operations. The Plan shall also specify which records must be kept to document these operation and maintenance procedures. These records shall comply with the requirements of Sections 504 and 505. The Plan shall be implemented upon approval of the Air Pollution Control Officer.

402 CALCULATION FOR DETERMINATION OF VOC CONTENT PER VOLUME OF COATING: The volume of coating material is defined as the volume of the original coating, plus any VOC- containing material added to the original coating. The original coating is the coating before any VOC-containing material such as solvent is added for purposes of mixing or thinning. The weight of VOC per combined volume of VOC and coating solids, shall be calculated by the following equation:

500 MONITORING AND RECORDS

501 TESTING PROCEDURES: A result by any of the below listed test methods which shows non-compliance with any provision of the rule shall constitute a violation of the rule.

502 COATING RECORDS: A person subject to this rule shall maintain the following daily records for each coating line:

503 SOLVENT RECORDS: A person subject to this rule shall maintain the following daily records for each container assembly line:

504 RECORD RETENTION: A person required to maintain records specified in Sections 502, 503, and 505 shall retain such records on-site for two years and make such records available for review by the Air Pollution Control Officer upon request.

505 CONTROL EQUIPMENT: Any person using an emission control system pursuant to Section 302 as a means of complying with this rule shall maintain such records as required by the Operation and Maintenance Plan in Section 401 on a daily basis.
