Delaware medical waste rules at a glance
| Governing agency | Delaware Department of Natural Resources and Environmental Control (DNREC), Division of Waste and Hazardous Substances |
|---|---|
| Primary statute / rule |
|
| Generator registration | Every medical facility that generates any amount of infectious waste must obtain an Infectious Waste Identification Number from DNREC for each site that generates the waste, by submitting a registration on a form provided by the Department, and must file an annual report describing how the waste was handled. [source] |
| On-site storage time limit | Infectious waste may be stored up to 14 days at room temperature (18 to 28 degrees Celsius), up to 45 days under refrigeration (2 to 7 degrees Celsius), and up to 90 days frozen in a freezer not used for food or patient-related items, per Section 11.8.5.3. Sharps placed in a sealed, leak-proof sharps container are exempt from the storage time limit. [source] |
| Approved treatment methods |
|
| Transport / manifest rules | A generator must complete a manifest before shipping, or causing the shipment of, infectious waste off site (Section 11.16.1). Any person who transports infectious waste must hold a Solid Waste Transporter Permit from DNREC, and the treatment facility operator must send one copy of the completed manifest back to the generator no later than 15 calendar days after the waste is treated. [source] |
| On-site treatment allowed? | Yes. A generator may treat infectious waste on site to render it non-infectious and non-recognizable using a process or equipment approved by the Department prior to disposal, provided treatment efficacy is demonstrated through initial and periodic verification testing (Section 11.5.1). [source] |
| Penalty range | Under 7 Del. C. Chapter 60: civil penalty of not less than $5,000 nor more than $40,000 for each completed violation, with each day a continuing violation treated separately (Section 6005); an administrative penalty up to $40,000 per day (Section 6005); and a criminal fine of not less than $2,500 nor more than $25,000 for each day of a willful or negligent violation (Section 6013).

What is unique about Delaware
Delaware folds infectious waste into its Solid Waste regulations rather than a standalone medical-waste statute. The operative rules sit in one section, 7 DE Admin Code 1301 Section 11.0, administered by DNREC's Division of Waste and Hazardous Substances. Two features stand out: the state assigns each generating site its own Infectious Waste Identification Number and requires an annual report, and the treatment standard is performance-based (any Department-approved method that renders the waste noninfectious, proven by efficacy testing) rather than a closed list of technologies. The storage clock is unusually explicit, running 14, 45, or 90 days keyed to room, refrigerated, or frozen temperatures, while sharps in sealed sharps containers carry no storage time limit (Section 11.8.5.3).
Frequently asked questions
Which agency regulates medical and infectious waste in Delaware?
The Delaware Department of Natural Resources and Environmental Control (DNREC), specifically its Division of Waste and Hazardous Substances, regulates the packaging, storage, treatment, transport, and disposal of infectious waste under 7 DE Admin Code 1301 Section 11.0, with enforcement authority from 7 Del. C. Chapter 60.
Do Delaware infectious-waste generators have to register?
Yes. Each site that generates infectious waste must obtain an Infectious Waste Identification Number from DNREC using the Department's registration form, and must submit an annual report describing how its waste was handled (Section 11.1.1).
How long can infectious waste be stored on site in Delaware?
Up to 14 days at room temperature (18 to 28 degrees Celsius), up to 45 days refrigerated (2 to 7 degrees Celsius), and up to 90 days frozen in a freezer not used for food or patient items. Sharps sealed in a designated sharps container are exempt from the storage time limit (Section 11.8.5.3).
Can infectious waste be treated on site in Delaware?
Yes. A generator may treat waste on site to render it non-infectious and non-recognizable using a process or equipment approved by DNREC, with treatment efficacy demonstrated through initial and periodic verification testing (Section 11.5.1). Pathological waste must instead be incinerated, cremated, or interred.
