President Biden is expected to sign the Sergeant First Class Heath Robinson Honoring Our Promise to Address Comprehensive Toxics (PACT) Act into law Monday, expanding benefit for up to 3.5 million veterans exposed to toxins during their service.

But the Department of Veterans Affairs isn’t waiting. It has established a website explaining the soon-to-be law. The site also has a link to file a claim.

“Once the President signs this bill into law, we at VA will implement it quickly and effectively, delivering the care these veterans need and the benefits they deserve,” VA Secretary Denis McDonough said in a statement, according to Military.com.
