The air can be impacted in many ways by your business. Solvents you use could evaporate into the air; refrigerants can be released into the air; dust can be generated and swept into the air; and smoke can carry any number of contaminants. This section will guide you through an examination of some potential sources of air pollution at your facility.

(1) Do you open burn any materials on your property?

“Open burning” is the burning of any materials whereby air contaminants resulting from combustion are emitted directly into the air, without passing through a stack or chimney from an enclosed chamber.

Open burning is prohibited! If you burn any materials, you will need to submit an RTC plan form. To be in compliance, you will need to immediately cease all open burning. Clean the burn area and remove any solid waste and ash to a state-approved solid waste management facility or recycling facility, as appropriate. Submit to IDEM documentation of arrangements to have solid waste picked up by a solid waste hauler (e.g., receipts).

For more information about open burning, visit the IDEM Web site.

Illegal open burning in a barrel.

(2) Do you use solvent(s) (cleaners/degreasers) at your facility?

If “NO”, skip question 2a.

There are many types of commercial solvents available for cleaning grease, oil and dirt from engines and parts. Gasoline, brake cleaner, and paint thinner can be considered solvents. Know what types of solvents you have at your facility and maintain a Material Safety Data Sheet (MSDS) for each solvent.

(2a) Do you store your solvent(s) in a closed container(s) when not in use?

A solvent container can be a parts washer (degreaser). Examine all solvent containers (including parts washers) to ensure all lids are tightly sealed. If not, you will need to submit an RTC plan form. To be in compliance, you will need to close all containers when not in use and submit documentation to IDEM (e.g., photos).

(3) Do you generate any particulate matter (i.e., dust, smoke, etc.) that crosses the property line?

Examine your property for signs that particulate matter (dust or smoke) is visibly crossing your property line at or near ground level. The following activities/areas may create particulate matter that can cross the property lines:

  • torching;
  • welding;
  • driving on gravel or dirt parking areas or roadways; and,
  • moving equipment and inventory aroundyour property.

If there is visible particulate matter crossing the property line, you must submit an RTC plan form that indicates and documents that you have contacted IDEM’s Office of Air Quality for guidance on how to prevent fugitive dust and emission violations. To obtain information, call IDEM’s Air Compliance Section at (800) 451-6027 ext. 3-0178 or (317) 233-0178. Information is also available on the IDEM Web site.

(4) Do you use a sweat furnace at your facility?

A sweat furnace is used to melt mixed aluminum scrap into more uniform, saleable ingots or sows.

If your facility uses a non-permitted sweat furnace, you will need to submit an RTC plan form. Submit to IDEM documentation that you have contacted IDEM’s Office of Air Quality (OAQ) for guidance on how to obtain a permit and comply with the appropriate emission limits, performance testing, and operating and monitoring requirements.

For information concerning the requirements for sweat furnaces, contact IDEM at (800) 451-6027, ext. 3-0178 or (317) 233-0178.

More information is available on the IDEM Web site.

For information about sweat furnace operation, see U.S. EPA's Sweat Furnace Operations Brochure or Appendix: Air.

(5) Do you keep records documenting the appropriate removal of refrigerants from vehicles, appliances (e.g., refrigerators and air conditioners), or other equipment?

Ensure that records are maintained for every vehicle going for final disposal (e.g., crushing, scrapping). If you do not have records documenting the appropriate removal of refrigerants from the vehicles at your facility, you will need to submit an RTC plan form. To be in compliance, you will need to maintain records with the following information for every vehicle brought to your site:

  1. a signed statement that refrigerants have been legally removed;
  2. the name and address of the person recovering the refrigerant;
  3. the date the refrigerant was removed; or,
  4. a contract that the refrigerant will be removed.

You will need to maintain and submit a record to IDEM. For an example of this refrigerant removal form for recordkeeping, see Appendix: Air.

(6) Do you collect refrigerants in U.S. EPA - approved devices?

All refrigerants must be collected in U.S. EPA-approved devices. An approved device must be certified. Certification shall take the form of a statement signed by the owner of the equipment or another responsible officer and setting forth:

  • the name and address of the purchaser of the equipment, including the county name;
  • where each piece of equipment is or will be located;
  • the number of service trucks (or other vehicles) used to transport technicians and equipment between the establishment and job sites and the field;
  • the manufacturer name, the date of manufacture, and if applicable, the model and serial number of the equipment; and,
  • a statement that the equipment will be properly used in servicing or disposing of appliances and that the information given is true and correct.

Owners or lessees of recycling or recovery equipment having their places of business in Indiana must send their certifications to:

CAA section 608 Enforcement Contact
EPA Region V (AE17J)
77 West Jackson Blvd.
Chicago, IL 60604-3507.

If your equipment is not certified by the U.S. EPA, you will need to submit an RTC plan form that indicates and documents that you have called the Stratospheric Ozone Hotline at (800) 296-1996 and certified your equipment.

(7) Do you release refrigerants into the atmosphere?

Refrigerants cannot be released into the atmosphere. If you do not currently collect refrigerants, you will need to submit an RTC plan form. To be in compliance, you will need to cease all releases of refrigerants to the air. Do not cut or puncture refrigerant lines.

Ensure that all refrigerants are collected and contained in an U.S. EPA-approved device. Submit to IDEM proof that refrigerants are collected in an approved manner (e.g., a receipt for equipment purchase).

(8) Are refrigerants removed from vehicles prior to storing them in the yard?

You should remove all refrigerants from all vehicles (non-drivable) prior to storing them in the yard. Removing refrigerants prior to storing them in the yard will reduce the chance for an accidental release to the environment as vehicles age in your yard.

(9) Are employees trained to remove and capture refrigerants?

Ensure that all employees who deal with refrigerants at your facility receive training to remove and capture refrigerants. Proper training of employees will reduce the chance for accidental refrigerant releases in the environment. For training and certification programs, call the Stratospheric Ozone Hotline (800) 296-1996 or visit U.S. EPA’s Web site.

(10) Are all air conditioner openings sealed after evacuation to prevent leaking of residual refrigerant?

Ensure that all air conditioner openings are sealed after evacuation. Sealing the air conditioner openings will reduce small releases into the environment.

(11) Are all collection/storage devices inspected to ensure they are not overfilled?

Initiate an inspection program to ensure that all your refrigerant storage devices are not overfilled. An inspection program will reduce the chances of accidental releases into the environment.
