New Hampshire medical waste rules at a glance
| Governing agency | New Hampshire Department of Environmental Services, Solid Waste Management Bureau |
|---|---|
| Primary statute / rule |
|
| Generator registration | New Hampshire does not impose a distinct infectious-waste generator registration or permit. Infectious waste is regulated as a solid waste under RSA 149-M and Env-Sw 904, and the permitting and quarterly quality-assurance testing obligations in Env-Sw 904.07 fall on facilities that treat the waste (including a generator that treats on site by a non-incineration method), not on generators who simply produce and ship waste off site.

| On-site storage time limit | Infectious waste may not be stored at room temperature in excess of 72 hours and must be maintained in a nonputrescent state using refrigeration when necessary, per Env-Sw 904.02. Facilities receiving infectious waste from off-site generators may not store it more than 7 days from date of receipt. [source] |
| Approved treatment methods |
|
| Transport / manifest rules | Env-Sw 904.06 does not require a state cradle-to-grave manifest. It requires double-bagging (a sealed nonpermeable 3 mil polyethylene bag inside a second sealed bag), labeling the outermost container with the words "Infectious waste" or "Biohazard waste" or the universal biohazard symbol plus the name, address, and telephone number of the generator and transporter, and compliance with federal DOT hazardous materials rules (49 CFR 171 to 180). The transporter must notify the receiving facility before delivering infectious waste to a New Hampshire landfill. [source] |
| On-site treatment allowed? | Yes. Env-Sw 904.07 expressly contemplates generator facilities that treat infectious waste by methods other than incineration, conditioned on initial quality-assurance efficacy verification, ongoing testing at least four times yearly to Env-Sw 904.03(a), and keeping those records at least 3 years. [source] |
| Penalty range | Civil penalty up to $25,000 per violation or per day of a continuing violation (RSA 149-M:15). Separately, the commissioner may impose an administrative fine up to $2,000 per offense (RSA 149-M:16). Criminal fines up to $25,000 per offense are also available under RSA 149-M:15. [source] |
What is unique about New Hampshire
New Hampshire sets a performance-based treatment bar rather than mandating a specific technology: infectious waste must reach high-level disinfection plus a 4 Log10 reduction of Bacillus subtilis or Bacillus stearothermophilus (Env-Sw 904.03(a)), and any on-site non-incineration treater must prove it with quality-assurance testing at least four times a year and keep records for 3 years (Env-Sw 904.07). The state also caps room-temperature storage at 72 hours (Env-Sw 904.02) and does not run a state infectious-waste manifest system, relying instead on double-bagging, labeling, and federal DOT rules plus prior notice to the receiving facility (Env-Sw 904.06).
Frequently asked questions
Which agency regulates medical and infectious waste in New Hampshire?
The New Hampshire Department of Environmental Services (NHDES), through its Solid Waste Management Bureau, under RSA 149-M and the Env-Sw 904 infectious waste rules.
How long can infectious waste be stored in New Hampshire?
Env-Sw 904.02 prohibits storing infectious waste at room temperature for more than 72 hours, and it must be kept nonputrescent using refrigeration when needed. A facility receiving waste from off-site generators may not hold it more than 7 days from date of receipt.
Does New Hampshire require a manifest to transport medical waste?
No. Env-Sw 904.06 does not establish a state manifest system. It requires double-bagging, labeling with "Infectious waste" or "Biohazard waste" or the biohazard symbol plus generator and transporter contact details, compliance with federal DOT rules (49 CFR 171 to 180), and prior notice to a receiving New Hampshire landfill.
Can a generator treat infectious waste on site in New Hampshire?
Yes. Env-Sw 904.07 contemplates generator facilities treating waste by non-incineration methods, provided they verify efficacy initially, run quality-assurance testing at least four times per year to meet the Env-Sw 904.03(a) standard, and keep the records for at least 3 years.
Can untreated infectious waste be landfilled in New Hampshire?
No. Under Env-Sw 904.04, untreated infectious waste may not be landfilled in New Hampshire. It must first reach high-level disinfection plus a 4 Log10 reduction of Bacillus subtilis or Bacillus stearothermophilus (Env-Sw 904.03(a)), and any incineration must also meet the Env-Sw 700 air rules. An on-site non-incineration treater must verify efficacy with quality-assurance testing at least four times a year and keep the records for at least three years.
