Background Information

Medical waste differs from hazardous waste. Hazardous waste is regulated by the US EPA (and related state rules) under the Resource Conservation and Recovery Act. Medical waste is not covered federal environmental laws or US EPA regulations (with the exception of a medical waste that also meets the definition of hazardous waste). Rather, medical waste is mostly controlled by state law and associated regulations. In addition to state environmental agency laws/rules, aspects of medical waste management are also controlled by the Occupational Safety & Health Administration (federal and/or state) and Department of Transportation (federal and state).

Each of our 50 states have developed rules and implemented regulations for medical waste. The state rules vary to some extent, including terminology. Depending on which state you live in, you may hear the terms regulated medical waste, biohazardous waste or infectious medical waste. In most cases, these terms all refer to the same thing: that portion of the medical waste stream that may be contaminated by blood, body fluids or other potentially infectious materials, thus posing a significant risk of transmitting infection.

Most states have regulations covering packaging, storage, and transportation of medical waste. Some states require health care facilities to register and/or obtain a permit. State rules may also cover the development of contingency plans, on-site treatment, training, waste tracking, recordkeeping, and reporting.

In most states, the environmental protection agency is primarily responsible for developing and enforcing regulations for medical waste management and disposal. Although in some states, the department of health may play an important role or even serve as the primary regulatory agency. Where both agencies are involved, typically the department of health is responsible for on-site management and the environmental agency is responsible for transportation and disposal.

OSHA, whether it is the U.S. Department of Labor Occupational Safety & Health Administration or an OSHA state program (24 states operate their own program), regulates several aspects of medical waste, including management of sharps, requirements for containers that hold or store medical waste, labeling of medical waste bags/containers, and employee training. These standards are designed to protect healthcare workers from the risk of exposure to bloodborne pathogens. However, they also help to systematically manage wastes, which benefit the public and environment.

Regulated medical waste is defined by the US Department of Transportation as a hazardous material. DOT rules mostly apply to transporters rather than healthcare facilities; although, knowledge of these rules is important because of the liability associated with shipping waste off-site.

Definition of Regulated Medical Waste

The term "special waste from health-care-related facilities" (SWFHCRF) is used to define regulated waste, including:

Animal waste from animals intentionally exposed to pathogens;
Bulk human blood and blood products;
Pathological waste;
Microbiological waste; and
Sharps.

A chain of events is necessary to produce disease from contact with medical waste:

The waste must contain a viable (capable of living/reproducing) human pathogen (disease producing organism);
A portal of entry must exist for an organism to enter the body;
There must be a sufficient number of organisms entering this portal of entry to produce an infection; and
There must be a susceptible host, and if infection does occur, disease may or may not occur.

Sharps, due to their inherent ability to provide a portal of entry, must be managed properly regardless of their contamination status.

The OSHA Bloodborne Pathogen Standard also defines regulated medical waste. This definition applies to waste within a facility. It is more comprehensive that the state’s SWFHCRF definition. This is because "universal precautions" must be observed in facilities where actual physical contact with potentially infectious materials can be expected to occur on a regular basis.

*Texas regulations are based on the idea that waste properly packaged and labeled at the point of generation reduces the amount of waste that needs to be handled by special means. Compliance with OSHA and Texas regulations can be achieved by simply re-evaluating what waste goes where at the point of generation.

*OSHA only requires a waste container marked with the BIOHAZARD symbol and word, although "red bags" may be substituted. If these bags are used to collect medical waste that is not SWFHCRF, their identity should be changed so

waste handlers will not be alarmed. Designation of the BIOHAZARD container should be documented in the Exposure Control Plan. The specified receptacle may then be lined with a regular trash bag, which may be disposed of as routine municipal solid waste if it does not contain any items of SWFHCRF.

Managing Regulated Medical Waste

Texas has designed comprehensive regulations that track medical waste from generation to disposal.

Treatment and Disposal of Treated Medical Waste

Specific categories of SWFHCRF may be treated by specific methods. Chlorine disinfection/maceration and moist heat disinfection require shredding of the waste during or shortly after treatment.

Other parameters including such things as time, temperature and pressure requirements are specified for other methods.

The U.S. Environmental Protection Agency (EPA) requires registration of chemical disinfectants (except for household bleach or 70 percent isopropyl alcohol). EPA also requires that liquid disinfectants be drained from treated wastes.

Approval from the Office of Air Quality of the Texas Natural Resource Conservation Commission (TNRCC) is required for incineration processes.

Any generator that produces more than 50 pounds per calendar month of SWFHCRF and that treats all or part of the wastes on-site is required to perform routine performance monitoring based on the volume of SWFHCRF generated monthly and the type of treatment process utilized.

On-Site vs. Off-Site Treatment

"On-site" means a facility consisting of contiguous structures or contiguous properties, or a combination of structures operated by a single entity operating under a license issued by the Texas Department of Health.

A frequently encountered situation involves the waste disposal activities of a hospital that owns a separate building containing physicians’ offices. Facilities that meet certain criteria may be able to handle such waste as their own "on-site generated" waste. If the hospital accepts and processes waste that was generated off-site, then that hospital then takes on the role of a commercial processor and must be permitted as a commercial facility.

On-Site Treatment

Records must be kept for waste treated on-site to include the date, amount of waste, method of treatment, name and initials of the person performing treatment, and for generators of more than 50 pounds per month, a written procedure for the operation and testing of any equipment or chemicals used. Records must be maintained for three years and must be available for review on request.

Treated wastes may be disposed of as routine municipal solid waste provided any markings identifying the waste as SWFHCRF are covered with a color-coded disposable container or a label identifying the waste as "treated." Recognizable human body parts, tissues, fetuses, organs, and the products of spontaneous or induced abortions must not be disposed of in a municipal solid waste landfill.

Sharps must be placed in containers designed for their disposal. Treated or unused sharps, if not encapsulated, must be segregated from the regular solid waste stream and transported without compaction to the landfill. If the contents of a sharps container are completely encased in an encapsulating matrix and can withstand an applied pressure of 40 pounds per square inch, the sharps container may be disposed of with routine municipal solid waste. Treated and/or encapsulated sharps containers must be labeled as such.

Off-Site Treatment

Wastes to be transported off-site for treatment must be packaged securely in a bag of specified strength requirements and subsequently boxed in a rigid outer container also meeting specified strength requirements. The outer container must be labeled twice in English and twice in Spanish with the words "CAUTION, contains medical waste that may be biohazardous."

Sharps must be placed in marked and puncture-resistant containers designed for their disposal.

Ultimately, the generator's primary responsibility whenever allowing untreated SWFHCRF to be transported off-site is to determine that the waste is being released to a currently registered transporter and to obtain a signed receipt for each shipment of regulated waste.

Transport of Medical Waste

Transporters of untreated medical waste must comply with applicable vehicle, financial assurance, registration, reporting, and fee requirements.

Certain exemptions exist for generators who choose to transport their own untreated medical waste:

Generators of less than 50 pounds per month may transport their own waste to a registered medical waste collection station, transfer station, storage facility, or processing facility without meeting transporter requirements.
Generators of more than 50 pounds per month may still transport their own waste provided they meet all transporter requirements except registration.
Generators located contiguous to a permitted processing facility may transport their own untreated waste without complying with packaging requirements provided the waste is identified as "untreated" and is not transported over a public roadway.

Transfer of shipments of untreated medical waste must take place only at and on the premises of a permitted transfer station, storage facility, or processing facility. In case of vehicle malfunction or accident, the waste may be transferred to another vehicle, and the TNRCC must be notified within five days in the case of vehicle malfunction or one day in the case of an accident. Interstate transportation requires the same conditions as for transporters operating within Texas, except that only the vehicle requirements apply to transporters of waste that neither originates nor terminates in Texas.

A licensed hospital may act as a medical waste collection station, may be registered in counties of less than one million population, and may accept waste only from generators of less than 50 pounds per month that transport their own untreated waste.

Storage

All medical waste must be stored in a secure manner and location that affords protection from theft, vandalism, inadvertent human or animal exposure, rain, water, and wind. It must be managed so it will not provide a breeding place or food for insects or rodents and will not generate noxious odors.

A permit is required for the storage of medical waste generated off-site except on the premises of a permitted processing facility or medical waste collection station. Such waste must be maintained at a temperature of 45 degrees Fahrenheit or less if held for more than 72 hours.

For registered transporters whose base of operations is located more than 200 miles from a permitted processing facility, untreated medical waste may be held up to one week without refrigeration. Medical waste generated off-site and held for more than 14 days is considered to be in storage, and authorization from TNRCC’s executive director is required.

OSHA Regulations HERC OSHA State Page

In addition to the state medical waste environmental regulations there are some Occupational Safety and Health Administration (OSHA) rules that apply to medical/infectious waste. Texas is one of 26 states covered entirely by the federal OSHA program. This program is operated by the Occupational Safety and Health Administration. OSHA rules (Occupational Exposure to Bloodborne Pathogens Standards) impact various aspects of medical/infectious waste, including management of sharps, requirements for containers that hold or store medical/infectious waste, labeling of medical/infectious waste bags/containers, and employee training.
