Section 326IAC8-10-5. Work practice standards

   (a) The owner or operator of a refinishing facility subject to this rule shall ensure that spray guns are cleaned in an enclosed device that:

(1) is closed during:

(A) spray gun equipment cleaning operations except when depositing and removing objects to be cleaned; and

(B) noncleaning operations with the exception of the maintenance and repair of the cleaning device itself; and

(2) recirculates cleaning solvent during the cleaning operation so that the solvent is available for reuse on site or for disposal off site.

The cleaning device shall be operated and maintained according to the manufacturer's recommendations. The owner or operator of the refinishing facility subject to this rule shall have the cleaning device manufacturer's recommendations available for inspection upon request by the department or the U.S. EPA.

  (b) The owner or operator of a refinishing facility subject to this rule shall use one (1) or a combination of the following equipment for coating application:

(1) Electrostatic equipment.

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

(3) Any other coating application equipment that has been demonstrated, by the owner or operator, to the satisfaction of the department to be capable of achieving at least sixty-five percent (65%) transfer efficiency. The owner or operator must submit sufficient data for the department to be able to determine the accuracy of the transfer efficiency claims.

Coating application equipment shall be operated and maintained according to the manufacturer's recommendations. The owner or operator shall have the manufacturer's recommendations available for inspection upon request by the department or the U.S. EPA.

  (c) The owner or operator of a refinishing facility subject to this rule shall implement housekeeping practices, which include the following:

(1) All:

(A) paper;

(B) cloth;

(C) plastic; or

(D) other materials;

used for activities such as surface preparation and surface cleanup that have been contaminated with coatings or solvent shall be stored in closed containers until disposed of off site. The containers shall remain closed unless being filled or emptied.

(2) Except when actively or directly applying, store in closed containers, all fresh or used refinishing materials including, but not limited to, the following:

(A) Solvents.

(4) Waste coatings and used automotive fluids shall be stored in closed containers.

(5) Equipment cleanup shall be performed with methods that minimize the use of solvents. Reasonable efforts shall be made to reclaim the bulk of used solvents. No cleaning shall be performed by direct spraying of solvents into the atmosphere.

(6) Effort shall be made to schedule operations of a similar nature to significantly reduce total VOC material consumption.

(7) Coatings or surface preparation products shall be applied in a manner that minimizes overspray.

  (d) The owner or operator of a refinishing facility subject to this rule shall comply with the training requirements of this rule as follows:

(1) Develop a written training program. The training program may include training provided by the manufacturer or supplier and shall include written procedures and hands-on demonstration, as appropriate, on the following topics:

(A) Identification of appropriate coatings or surface preparation products.

(B) Preparation of coatings or surface preparation products according to coating manufacturer, distributor, or owner or operator's recommendations.

(C) Application of coatings or surface preparation products or organic solvents using techniques that minimize their usage.

(D) Operation and maintenance of spray gun cleaning equipment to minimize evaporation of organic solvents to the atmosphere.

(E) Work practice standards established in subsection (c).

(F) Procedures to:

(i) gather;

(ii) record;

(iii) monitor; and

(iv) report;

data in accordance with section 9 of this rule.

(iii) The name of the person providing the supervision.

(4) The owner or operator of the refinishing operation subject to this rule shall keep records of the training program. The records shall consist of the following:

(A) The date training was completed.

(B) A list of persons, by name and activity and the topics in which they have been trained.

(C) A statement signed by the trainer certifying each trainee who satisfactorily has completed training in the topics and is proficient in the procedures specified in subdivision (1).
