Federal regulations require all RCRA hazardous waste Large Quantity Generators (LQGs) to submit a report summarizing the waste they generated and where it went. This “Biennial Report” is due by March 1 of each even-numbered year, and it only covers hazardous waste generated the previous year (2023, this go-round).

You may ask, “How do I know whether this applies to me?” You are a RCRA LQG if your facility:

  • Generated, in one calendar month, greater or equal to 1,000 kg (2,200 lbs.) of non-acute RCRA waste, or
  • Generated, in one calendar month, or accumulated at any time, greater than 1 kg (2.2.lbs) of RCRA acute hazardous waste, or 
  • Generated, in one calendar month, greater than 100 kg (220 lbs.) of any residue or contaminated soil, waste, or other debris resulting from the cleanup of a spill, into or on any land or water, of any RCRA acute hazardous wastes and/or
  • Permitted treatment, storage, recycled, or disposed of RCRA hazardous wastes on-site.
  • Only RCRA hazardous waste counts towards this applicability

The Biennial Report includes the EPA Site Identification (Site ID) form for your site plus one “waste generation and management” (GM) form for generally each waste generated, with certain exclusions and exceptions. 

For California generators, and some other states, Biennial Reports must be submitted through the EPA RCRAinfo system: (https://rcrainfo.epa.gov/rcrainfoprod/action/secured/login). 

Other states may have different requirements for submittal. Whatever your state, reports for 2023 activities are due by March 1, 2024, so it’s high time to start preparing and gathering your hazardous waste information!

We have recently learned that there are new error messages in RCRAinfo Biennial Report. One of which accounts for a weight discrepancy of 10 percent or more and this could be related to the recent change from the CA DTSC: RCRA LQG in CA filing biennial reports must include Non-RCRA and exported hazardous waste, as additional GM forms (Waste Generation and Management Forms). While this was unexpected for us and likely was for you, too, ACTenviro is adapting to the changes in real time and has a working plan that includes direct communication with the DTSC. 

What we’re still learning: 

  • The reason why CA DTSC is requesting Non-RCRA and exported waste streams 
  • Their leniency with RCRA LQGs generators this year 
  • The impact on states outside of CA. 

If you have any questions or would like assistance preparing your 2023 Biennial Report, please reach out to your ACTenviro account manager. If you don’t already have an account manager, email us at [email protected] and we will route you to the appropriate person.

ACT proudly sponsored the El Paso, TX, St. Pius X Special Needs Group during July’s Special Olympics World Games in Los Angeles. St. Pius X’s Ballet Folklorico troupe, which included Erica Ruiz, the niece of our very own Margie Fierro, performed at USC on both Sunday the 26th and Monday the 27th. The World Games, a once in a lifetime celebration at which there were over 7,000 athletes from around the world, were the largest sporting event in the world for 2015.

Pasquale Paduano, our Vice President of Operations, is very proud of ACT and his staff for their hard work and their sponsorship of this year’s games and the Ballet Folklorico group.



aug.21.2015-inc-500Once again, Inc. Magazine has placed ACT Environmental Services on its annual Inc. 500/5000, a ranking of the nation’s fastest-growing privately held companies. This marks the 6th year running that ACT has made the exclusive list. Several Fortune 500 companies have appeared on the Inc. 500/5000 list in the past – companies like LinkedIn, Yelp and Dell – but ACT is among less than 1% of companies to have done so 6 times!

“Making this list once is a great testament, but 6 times reflects our company goals,” said Walter H. Singer, President and Founder of ACT Environmental Services. “Our team’s continued hard work, passion and dedication to each other and our clients is why we grow each year.”

aug.4.2015-group-shotEveryone at ACT’s headquarters gathered for a group lunch to celebrate some notable accomplishments:




10 years of service from Alex Guerrero
We cannot thank Alex enough for his decade of commitment and dedication to our mission. Employees like Alex make up the backbone, not to mention the heart, of ACT.
