Medical waste rules in Thornton, CO
Colorado regulates medical waste through the Department of Public Health and Environment (CDPHE) under Section 13 of the Solid Waste Regulations, 6 CCR 1007-2, Part 1 (materials referenced as of November 16, 2021). Generators do not register, but each must keep a written medical waste management plan and stay inside the accumulation limits that keep it out of the permit system.
- Scope (Section 13.1): every non-household generator, transporter and treatment, storage or disposal facility handling non-hazardous medical waste, a term that covers infectious waste, trace chemotherapy waste and waste pharmaceuticals. Hazardous waste pharmaceuticals follow 6 CCR 1007-3 instead, and controlled substances follow US DEA rules (Section 13.9.3).
- Management plan (Section 13.4): each facility names an employee responsible for the plan, which identifies the types of medical waste and where they are generated, describes how each is identified, segregated, packaged, stored, treated, transported and disposed of, includes a spill contingency plan and the training given to employees, is kept on site for the regulator, the transporter and the disposal facility, and is updated whenever handling changes.
- Accumulation limits (Section 13.3.1 A): a generator storing its own waste needs no Certificate of Designation if putrescible medical waste, packaged to US DOT standards (49 CFR 173.196 or 173.197), is held for no more than 30 calendar days unrefrigerated or 90 days refrigerated at 45°F or below or frozen, and non-putrescible waste such as sharps containers, waste pharmaceutical containers and trace chemotherapy waste is held no more than 90 days in closed, secured containers. Exceeding those limits turns the practice into a storage facility that needs a certificate.
- General provisions (Section 13.2): no nuisance conditions; waste that causes them is refrigerated, frozen, treated or disposed of at once; no compaction of infectious waste before treatment; all records kept on site for three years in a retrievable form.
- Treatment (Section 13.6): thermal, chemical, irradiation or other approved methods that achieve at least a 4 log reduction of Bacillus spores and 6 log of Mycobacterium; encapsulation, solidification or compaction alone are not treatment. Trace chemotherapy waste and waste pharmaceuticals are incinerated, encapsulated or stabilised, or sent to a reverse distributor.
- Transport and disposal (Sections 13.9, 13.10): untreated medical waste goes only to an approved commercial storage, treatment or disposal facility; Colorado does not license medical waste transporters, and shipments follow the US DOT rules. Spills in transit are reported to CDPHE within 24 hours with a written report in 15 days. Treated infectious waste may go to a landfill or, for liquids, a secondary-treatment sewer with the utility's approval, provided it is identified as treated. Recognisable human anatomical remains are interred, cremated or incinerated.
