Section 326IAC8-22-3. VOC content limits

   (a) Except as provided in subsection (c) and section 4 of this rule, on and after April 1, 2011, an owner or operator applying miscellaneous industrial adhesives or adhesive primers within Lake County or Porter County shall comply with applicable VOC content limits specified in subsection (f).

  (b) The VOC content limits in subsection (f) for adhesives or adhesive primers applied to particular substrates shall apply as follows:

(1) If an operator uses an adhesive that is subject to a specific VOC content limit in subsection (f), the specific limit is applicable rather than an adhesive-to-substrate limit.

(2) The applicable substrate category with the highest VOC content shall be the limit when an adhesive is used to bond dissimilar substrates together.

  (c) A person using an adhesive or adhesive primer subject to this rule may comply with subsection (a) by using add-on air pollution control equipment if the equipment meets the following requirements:

(1) The VOC emissions from the use of all adhesives or adhesive primers subject to this rule are reduced by an overall capture and control efficiency of at least eighty-five percent (85%) by weight.

(2) The combustion temperature is monitored continuously if a thermal incinerator is operated.

(3) Inlet and exhaust gas temperatures are monitored continuously if a catalytic incinerator is operated.

(4) Control device efficiency is monitored continuously if a carbon absorber or control device other than a thermal or catalytic incinerator is operated.

(5) Operation records sufficient to demonstrate compliance with the requirements of this subsection are maintained as required by section 6 of this rule.

  (d) Work practices shall be used to minimize VOC emissions from mixing operations, storage tanks, and other containers, and handling operations for adhesives, adhesive primers, cleaning materials, and waste materials. Work practices shall include, at a minimum, the following:

(1) Store all VOC adhesives, adhesive primers, and cleaning materials in closed containers or pipes.

(2) Minimize spills of VOC adhesives, adhesive primers, and clean up any spill immediately.

(3) Convey any adhesives, adhesive primers, and cleaning materials in closed containers or pipes.

(4) Keep mixing vessels that contain VOC adhesives, adhesive primers, or other materials closed except when specifically in use.

(5) Clean equipment without atomizing the cleaning solvent and ensure all spent solvent is captured in a closed container.

  (e) In addition to the VOC content limits in subsection (f), one (1) or a combination of the following equipment shall be used for adhesive or adhesive primer application:

(1) Electrostatic equipment.

(2) High volume low-pressure (HVLP) spray equipment.

(3) Flow coating.

(4) Roller coating or hand application, including nonspray application methods similar to hand or mechanically powered caulking gun, brush, or direct hand application.

(5) Dip coating, including electrodeposition.

(6) Airless spray.

(7) Air-assisted airless spray.

(8) Other coating application method capable of achieving a transfer efficiency equivalent to or better than that achieved by HVLP spraying.

  (f) The VOC content limits for adhesives and adhesive primers are as follows:
