Mississippi medical waste rules at a glance

Regulated medical waste rules in Mississippi, at a glance
Governing agencyMississippi State Department of Health (generator standards) with MDEQ (off-site treatment, transport, disposal)
Primary statute / rule
Generator registrationMississippi does not impose a separate state generator registration or permit number for medical-waste generators. Every generator of infectious medical waste and medical waste, regardless of the quantity generated per month, must develop and maintain a written Medical Waste Management Plan covering storage, containment, treatment, and disposal under the MSDH Adopted Standards. [source]
On-site storage time limitUntreated infectious medical waste (except sharps in approved containers) may not be stored at the producing facility for more than seven days above a temperature of 6 degrees Celsius (38 degrees Fahrenheit). Storage at or below 0 degrees Celsius (32 degrees Fahrenheit) is permitted for not more than 90 days without specific approval of the Department of Health. [source]
Approved treatment methods
  • Incineration in an approved incinerator producing carbonized or mineralized ash (requires an MDEQ air-emissions permit)
  • Steam sterilization (autoclave) reaching at least 121 degrees Celsius (250 degrees Fahrenheit) for one-half hour or longer, with monthly biological-indicator verification
  • Chemical sterilization using EPA-recognized sterilants, with quarterly spore testing
  • Discharge of liquid or semi-liquid waste to an approved sewerage system, except where prohibited by MSDH
  • Incineration or interment for recognizable human anatomical remains

Transport / manifest rulesMississippi does not currently require state identification, certification, licensing, or a transport manifest for medical-waste transporters. Transport vehicles must be operated and maintained to prevent loss of liquids or solid waste, control odors and vector attraction, and promptly clean up any spillage. Under the Solid Waste Law the waste becomes the property of the commercial collector at the point of collection and of the treatment facility operator on delivery. [source]
On-site treatment allowed?Yes. Processing of solid waste at the site of generation is exempt from the MDEQ Nonhazardous Solid Waste Management Regulations, so a generator may treat its own infectious waste on site (for example by autoclave) provided it meets the MSDH treatment and operating standards. A commercial off-site treatment facility (one accepting waste for compensation or from more than one generator) must hold an MDEQ solid waste management permit. [source]
Penalty rangeUnder Miss. Code Ann. Section 17-17-29, a civil penalty of not more than $25,000 for each violation, assessed by the commission after a hearing. A knowing violation is a misdemeanor punishable by a fine of not more than $25,000 for each day of violation or imprisonment up to one year, or both, with each day a separate offense. [source]

What is unique about Mississippi

Mississippi splits oversight: the State Department of Health writes the generator-facing infectious-medical-waste standards (storage, containment, treatment) for the health care facilities it licenses, while MDEQ handles off-site treatment, transport, and disposal under the Solid Waste Law. Infectious and medical wastes are regulated as solid wastes, not hazardous wastes, unless they independently meet the hazardous-waste definition. Notably, MDEQ does not require any state permit, license, or identification for medical-waste transporters, and on-site processing at the point of generation is exempt from the nonhazardous solid waste regulations.

Frequently asked questions

Which agency regulates medical waste in Mississippi?

Two agencies share it. The Mississippi State Department of Health (MSDH) sets the generator standards for infectious medical waste in the health care facilities it licenses, and the Mississippi Department of Environmental Quality (MDEQ) regulates off-site treatment, transport, and disposal under the Mississippi Solid Waste Law (Miss. Code Ann. Section 17-17-1 et seq.).

How long can a generator store untreated infectious medical waste in Mississippi?

Untreated infectious medical waste (except sharps in approved containers) may not be stored more than seven days above 6 degrees Celsius (38 degrees Fahrenheit). If kept at or below 0 degrees Celsius (32 degrees Fahrenheit), it may be stored up to 90 days without specific MSDH approval, per the MSDH Adopted Standards.

Does Mississippi require a license or manifest to transport medical waste?

No. According to the MDEQ overview of these rules, the state does not currently require identification, certification, or a transport manifest for medical-waste transporters. Vehicles still must be operated and maintained to prevent spillage, odors, and vector attraction.

Can a Mississippi facility treat its own medical waste on site?

Yes. Processing solid waste at the site of generation is exempt from the MDEQ Nonhazardous Solid Waste Management Regulations, so a generator may treat its own infectious waste (for example by autoclave) if it meets the MSDH treatment and operating standards. A commercial off-site facility that accepts waste from others must hold an MDEQ solid waste management permit.
