Webinar: Safer alternatives for solvent applications

May 26, 2021, 11:30 am-1:00 pm CDT
Register here.

A range of many different types of solvents are used in diverse ways by thousands of companies in the nation. Find out how you can help those companies adopt pollution prevention (P2) measures by guiding them to safer alternatives. Get ideas on where and how to focus P2 efforts.

The US EPA P2 grant program describes several National Emphasis Areas (NEAs) and solvents are used extensively by companies in these NEA sectors. This webinar, sponsored by the Pacific Northwest Pollution Prevention Resource Center (PPRC), will identify nine major solvent applications used in two or more of the NEAs. They will describe:

  • How the solvents are used in the application
  • The types of solvents used
  • The safer alternatives that can be used in their place

Webinar attendees, including P2 program grantees, will have the opportunity to provide input on which solvent application areas they would like to learn more about. Additional webinars may be scheduled in the future that will cover the applications of interest and their alternatives in greater detail.

During the webinar, Dr. Wolf will answer questions on the solvents, safer alternatives, and implementation strategies.

Who should attend this webinar?

  • P2 program grantees
  • State and local government agency P2 technical assistance providers
  • EPA regional P2 staff
  • Industry representatives

Speakers

  • Jean Waters, Pacific Northwest Pollution Prevention Resource Center (PPRC)
  • Katy Wolf, Ph.D., Consultant

Stamper Says “So Long” to Lubricant Waste

Read the full story in Metal Forming Magazine.

A dozen new Unist programmable roll-coater lubrication systems installed on most of the presses at Tier Two automotive stamper Clover Tool Manufacturing Ltd., Concord, Ontario, Canada, have put a dramatic halt to the significant amount of wasted lubricant that once plagued its pressroom. Gone, too, are related downstream costs resulting from applying excess lubricant—items such as waste disposal and added die-change time spent setting up sprayers.

Riverdale Mills reduces use of toxics in coating process

Via the Toxics Use Reduction Institute.

When companies analyze where and how they use toxic chemicals, they can discover ways to reduce toxics.

In the case of Riverdale Mills, the wire mesh manufacturer isolated the problem and used ingenuity to develop an in-house, low-cost solution.

The company designed and built two dual-brush roller systems to isolate chemical baths and prevent contamination so that the chemicals could be pumped back into the process and reused.

View the webinar demonstration and read the case study to learn more about the development of the solution, implementation, expected return on investment and chemical reductions. 

EPA releases final risk evaluations for trichlorethylene (TCE) and carbon tetrachloride

U.S. EPA recently completed final risk evaluations for trichlorethylene (TCE) and carbon tetrachloride under the Toxic Substances Control Act (TSCA).

The next step in the process required by TSCA is risk management. EPA will propose and take public comments on actions to address the unreasonable risks identified in the risk evaluation. According to TSCA, the agency must finalize those actions within two years of completing the final risk evaluation. EPA’s proposed regulations could include requirements on how the chemical is used, or limiting or prohibiting the manufacture, processing, distribution in commerce, use, or disposal of this chemical substance, as applicable.

There will be additional opportunities for public participation. Just like the risk evaluation process, there will be opportunities for public comment as EPA works to propose and finalize risk management actions for TCE. You can stay informed by signing up for EPA’s email alerts or checking the public dockets at http://www.regulations.gov.

EPA Seeks Small Businesses Input on Risk Management Rulemakings for Carbon Tetrachloride and TCE

The U.S. Environmental Protection Agency (EPA) is inviting small businesses, governments, and not-for-profits to participate as Small Entity Representatives (SERs) to provide advice and recommendations to two Small Business Advocacy Review (SBAR) panels. There will be one panel for carbon tetrachloride and one panel for trichloroethylene (TCE). Each will focus on the agency’s development of proposed rules to address unreasonable risks identified in EPA’s recently completed Toxic Substances Control Act (TSCA) risk evaluations for these chemicals.

Under TSCA, EPA is required to evaluate the risks associated with exposure to existing chemicals in commerce using the best available science then take action to address any unreasonable risks identified. The agency issued a final risk evaluation for carbon tetrachloride in November 2020, showing unreasonable risks to workers under certain conditions of use. The agency also issued a final risk evaluation for TCE in November 2020, showing unreasonable risks to workers and consumers under certain conditions of use. EPA is now moving to the risk management step in the TSCA process by working to draft regulations to protect public health from the unreasonable risks identified in the final risk evaluations.

The Regulatory Flexibility Act requires agencies to establish a SBAR panel for rules that may have a significant economic impact on a substantial number of small entities. The SBAR panel will include federal representatives from the Small Business Administration (SBA), the Office of Management and Budget (OMB), and EPA.

SERs will be selected by the SBAR Panels to provide comments on behalf of their company, community, or organization and advise the panels on the potential impacts of the proposed rules on small entities. EPA is seeking self-nominations directly from the small entities that may be subject to the rule requirements. Other representatives, such as trade associations that exclusively or at least primarily represent potentially regulated small entities, may also serve as SERs.

SERs provide advice and recommendations to the panels. The SERs participate in consultations with the SBAR Panels via telephone, webinar, or in person in one or two meetings and are given an opportunity to submit written comments to the Panels. Self-nominations may be submitted through the link below and must be received by December 14, 2020.

In addition to engaging with small businesses, EPA is executing a robust outreach effort on risk management that includes formal consultations with state and local governments, tribes, and environmental justice communities. There will also be an open public comment on any draft risk management regulations.
