TX SB1290

Requires operators of "package plants" (pre-manufactured wastewater treatment facilities with capacity under 500,000 gallons per day) to maintain emergency operations capability during extended power outages lasting more than 24 hours following natural disasters

Operators must submit emergency preparedness plans to the Texas Commission on Environmental Quality (TCEQ) for approval, including a timeline for implementation; TCEQ has 90 days to review and recommend changes if needed

Acceptable emergency preparedness options include automatically starting auxiliary generators, shared generator capacity through mutual aid programs, leasing/contracting agreements, portable generators with quick-connect systems, on-site electrical generation, hardening electric infrastructure, or other commission-approved alternatives

TCEQ must adopt implementing rules by January 1, 2026; operators must submit plans by May 1, 2026, and implement approved plans by September 1, 2026

Emergency preparedness plan information is confidential and exempt from public disclosure; the commission must consider potential financial burden on customers when reviewing compliance
