Proposed Universal Waste Rule

WA-12-21 Universal Waste Rulemaking

The DNR is developing universal waste rules that would allow used aerosol cans to be managed as a universal waste. This change would benefit a wide variety of facilities generating and managing hazardous waste aerosol cans by:

• providing a clear, protective system for managing discarded aerosol cans;
• promoting collection and recycling of these cans; and
• encouraging development of municipal and commercial programs to reduce the quantity of aerosol cans going to municipal solid waste landfills or combustors. 

The rules would ensure clarity and consistency in waste requirements for universal waste receiving and recycling facilities or destination facilities.

Proposed Ignitable Liquids Rule

Wa-11-21 Modernizing Ignitable Liquids And Test Methods Rulemaking

The DNR is developing rules that would allow updated flash-point testing methods for ignitable hazardous waste determinations, including removing obsolete information in the ignitability regulation. These rules would standardize test procedures, update standards to match federal requirements, and potentially eliminate the need for outdated equipment and methodologies.

This rule would also define “aqueous” as “50% water by weight,” which would assist in narrowing the types of alcohol that would qualify as a hazardous waste, potentially reducing the applicability of these requirements to certain entities. These waste streams have low flash points but are unable to sustain combustion.

Another component of the rule would correct cross references to U.S. Department of Transportation regulations and remove obsolete information in the ignitability regulation. Specifically, the proposed rule would modify the criteria for ignitable compressed gases and oxidizers to adhere more closely to the corresponding definitions in the DOT Hazardous Materials Regulations.

Proposed Corrections Rule

Wa-14-21 Technical Corrections And Clarifications Rulemaking

Current state hazardous waste regulations contain spelling and grammatical errors, citation errors, and missing federal code language. The DNR is proposing this rule to update and correct state regulations, including any potential technical corrections finalized by the U.S. Environmental Protection Agency during the proposed rulemaking process. The proposed rules and revisions would correct and update current state rules that comprehensively regulate the generation, transportation, recycling, treatment, storage and disposal of hazardous and universal wastes and used oil.
