Hazardous Air Pollutants (HAPs) and
Ozone Depleting Chemicals (ODCs)

The 1990 Clean Air Act Amendments (CAAA) directed the U. S. Environmental Protection Agency (USEPA) to regulate emissions into the air of 188 toxic chemicals. These chemicals, called Hazardous Air Pollutants (HAPs), are known as suspected carcinogens, and have high usage and emissions in a wide variety of processes. EPA has determined that emissions of these chemicals present a threat to human health and the environment. As an owner or operator of equipment that uses products that contain chemicals, it is our responsibility to track and control any of the 188 regulated chemicals listed by the USEPA. The state of Texas also requires owners and operators of equipment to track and control Texas contaminants in addition to those listed by USEPA. Refrigerants containing fluorocarbon compounds that contain chlorine are harmful to the stratospheric ozone layer and thus they are also known as ODCs. Based on their potential to deplete ozone ODCs have been classified as either a Class I or Class II ODC and are regulated by Title VI of the Clean Air Act.

Aerospace NESHAP

Air Quality ProgramFort Hood must comply with rules and regulation affecting aerospace maintenance and rework facilities under 40 Code of Federal Regulation (CFR) 63, Subchapter GG. This NESHAP covers cleaning, engine flushing, aircraft washing, and painting operations. Use of hazardous materials during aviation maintenance procedures must be controlled and documented. Semi-annual and annual compliance certification is also another requirement of this regulation. Training on Aerospace NESHAP is required and available by contacting the DPW Environmental Division’s NESHAP Project Manager, (254)288-5284 or viewing the presentation at this link Aerospace NESHAP Requirements.


In 1997, Fort Hood conducted its base-wide asbestos survey of 2,606 buildings. This survey has been instrumental in conducting renovation, abatement and demolition of facilities located at Fort Hood. Asbestos on Fort Hood is regulated under 40 Code of Federal Regulation (CFR) 61, Subchapter M and rules of the Texas Department of Health. Maximum elimination of asbestos shall be implemented whenever conditions present the opportunity.

These activities will be achieved through:
  • normal attrition, replacing the component, and/or end-item with other materials as part of facilities renovations
  • using applicable open-ended contracts and other opportunities as funding and technology allows.

Defense Land System and Miscellaneous Equipment (DLSME) NESHAP

Air Quality ProgramFort Hood is awaiting promulgation of the new Defense Land System and Miscellaneous Equipment (DLSME) NESHAP which will cover all military surface coating operations and may include facility maintenance and area sources.

Use and Recovery/Recycle of ODCs

The use and recovery of ODCs (Ozone Depleting Chemicals) on Fort Hood is regulated by the USEPA under 40 Code of Federal Regulation (CFR) 82. All Fort Hood military, government and contract air conditioning and refrigeration service personnel including technicians/mechanics that procure, use, recover, remove, or recycle refrigerants or halons are required to follow the procedures outlined in the Fort Hood ODC Standard Operating Procedure.
Refrigerant recovery/recycle equipment must be registered with the Environmental Protection Agency. In order to comply with requirements of Fort Hood's Title V operating permit please complete the certification form and return it to the DPW Environmental Division's air program by email or (254) 287-2718(fax).

Accidental Release Reporting

In the event of accidental or unintentional release of Ozone Depleting Chemicals (ODCs) on Fort Hood, please immediately contact the Directorate of Public Works, Environmental Office (DPW-ENV), Air Program Manager, 287-8714 or 287-6499. The information requested is provided on the (right-click the link and select "Save Target As..") Accidental or Unintentional Venting Report.

How to obtain refrigerant technician certification

Air Quality ProgramThe EPA has established a technician certification program for persons ("technicians") who perform maintenance, service, repair, or disposal that could be reasonably expected to release refrigerants into the atmosphere. The definition of "technician" specifically includes certain activities as follows:
  • Attaching and detaching hoses and gauges to and from the appliance to measure pressure within the appliance.
  • Adding refrigerant to or removing refrigerant from the appliance.
  • Any other activity that violates the integrity of the refrigerant circuit while there is refrigerant in the appliance.
Air Quality ProgramIf you meet the definition of a “technician” and need to obtain certification; there are 5 separate levels depending on what you do. There are many vendors that offer certifications. For Motor Vehicle Air Conditioning, Section 609, one vendor that offers on-line certification is the Mobile Air Conditioning Society. For Section 608 Certifications (Types I, II, II and IV (Universal), you may obtain the Study Guide then request the certification test by contacting this office, DPW-ENV, 287-8755. There are monetary fees involved in all levels of certification, depending on the vendor.

What to do with equipment with refrigerant in it

Under 40 CFR Part 82, the EPA has established rules for air conditioning and refrigeration equipment that will be permanently retired, dismantled or otherwise disposed of. A certified refrigerant technician must remove all refrigerant from unserviceable equipment and prepare a refrigerant removal statement for the equipment. If the equipment is still serviceable and usable, it can be turned into DRMO without draining the refrigerant. For property book items such as window air conditioners and refrigerators, a work order (DA Form 2407) can be submitted through DOL Maintenance Customer Service Office, 287-5640/5338. Please contact DPW-ENV, 553-1581 if you have any questions.
