Montana has incorporated-by-reference revised RCRA regulations, including the Generator Improvements Rule provisions, effective May 14, 2022.

Update 04/25/2022

This week, we check in with twelve states (plus D.C.) that are still working to adopt the overhauled RCRA standards from the Generator Improvements Rule. 

California has a plan to adopt elements of the Generator Improvements Rule and reorganize its Title 22 regulations.

Connecticut is actively working with US EPA and expects to adopt the Generator Improvements within one year.

Kansas is working to adopt updates to the Federal hazardous waste regulations, including the GIR, the Hazardous Waste Pharmaceuticals Rule, and other rulemakings. Kansas anticipates that an adoption packet will be available by May 2023.

Maine expects to start drafting changes to its state hazardous waste management rules—including adoption of the GIR and the Hazardous Waste Pharmaceuticals Rule in 2023.

Massachusetts expects to propose a timeline for adopting the Generator Improvements in early 2023.

Minnesota plans to publish Land-Related Housekeeping Amendments in Summer 2022, with an expected effective date in Fall/Winter of this year. Minnesota will adopt some of the voluntary (i.e., more flexible) provisions from the GIR. Currently, the state does not plan to adopt the allowance for consolidation of VSQG waste nor the relief for episodic generation.

Montana plans to bring it state regulations up to date with the current RCRA regulations, with an anticipated implementation date as soon as May, 2022. (Update: Rulemaking finalized, effective 5/14/22).

Nebraska is in the process of adopting the Generator Improvements Rule in its entirety, with no precise timeline for implementation currently.

New Hampshire plans to adopt the Generator Improvements Rule on or before March 30, 2024.

New York will incorporate the GIR into its state regulations as part of an ongoing rulemaking project titled FedReg6, which also includes the Hazardous Waste Pharmaceuticals Rule, revisions to the Definition of Solid Waste (DSW), and relaxed management standards for waste airbags.

Missouri and Rhode Island are working through some state-specific issues with EPA before adopting the updated RCRA rules. Both states plan to adopt the GIR in the future.

Washington, D.C. is responding to public comments submitted on a proposal to incorporate-by-reference the revised hazardous waste regulations. The public comment period closed in March 2022.

To complete the above list, Lion is actively seeking an update on the status of the rule change in Guam

Louisiana and North Dakota each adopted the updates in EPA's Generator Improvements Rule in July 2020,

Update 5/19/20 
Indiana and Wyoming are the two states to most recently adopt EPA's Generator Improvements Rule. That means half the country (25 states) have now adopted the more stringent RCRA requirements. 

What is the Generator Improvements Rule?

The effective date for US EPA’s landmark Generator Improvements Rule (GIR) was May 30, 2017.

States with approved RCRA programs (i.e., all states other than Alaska and Iowa) must adopt at least the more-stringent regulations within one year of the Final Rule’s effective date. If a state needs to change its state law to accommodate changes to its hazardous waste program, the state gets two years to adopt the Generator Improvements Rule.

Both the one-year and two-year deadlines have now passed. If your state has not yet adopted the mandatory elements of the Generator Improvements Rule, you should expect them to very soon. 

How the Generator Improvements Rule Makes RCRA Stricter

The following are examples (not all-inclusive) of more stringent requirements from EPA's Generator Improvements Rule:

Waste Determinations

  1. The recordkeeping and retention requirements for hazardous waste determinations previously found at 40 CFR section 262.40(c) were moved into section 262.11(f), with clarifications on what records must be kept;
  2. Small and Large quantity generators must indicate waste codes on containers before shipping hazardous waste off site to a RCRA permitted treatment, storage, and disposal facility in accordance with the requirements of 40 CFR section 262.32; and
  3. Any generator managing a potentially hazardous waste should manage it in accordance with the generator regulations until such time that the generator is sure that the waste is not hazardous (e.g. while awaiting the results of analysis).

Marking and Labeling

The final rule added a provision for generators to mark hazardous waste containers with an indication of the hazards of the contents.

Emergency Preparedness and Prevention

The GIR added a requirement that the generator must keep documentation of the fact that it has made arrangements with local emergency responders.

LQG’s written contingency plan must include satellite accumulation areas and have a “quick reference guide.”


There are new closure reporting requirements for a large quantity generator’s 90-day central storage area.


Small quantity generators will be required to re-notify starting in 2021 and every four years thereafter using EPA Form 8700-12. This re-notification must be submitted by September 1st of each year in which re-notifications are required.

Watch your State Registers for official notification of when the GIR has been adopted in your state, keep an eye on Lion News for more updates in the future, or visit the EPA website for a list of state adoption activities.

If Your State Has Adopted the GIR... 

If your state is pictured in blue on the map above, check your state regulations to see if they adopted the GIR in its entirety.

States are not required to adopt anything that is less stringent then their current regulations.
New RCRA rules that are less stringent include:
  1. Allowing a hazardous waste generator to avoid increased burden of a higher generator status when generating episodic waste provided the episodic waste is properly managed
  2. Allowing a very small quantity generator (VSQG) to send its hazardous waste to a large quantity generator under control of the same person
  3. Venting containers at satellite areas for certain conditions
  4. Removing the need for the home address of Emergency Coordinators

What if My State Did Not Adopt the GIR Yet?

In states that have not yet adopted the Generator Improvements Rule, Lion recommends that generators comply with the stricter regulations. 

In the US, hazardous waste regulation is a joint effort between Federal and state agencies. When US EPA makes changes to the Federal program, states must adopt any updates that make the rules more stringent. States that fail to maintain hazardous waste regulations that are at least as stringent as the Federal RCRA program risk losing their authorization to run a state program.
