WA SB6246

Amends RCW 70A.65.110 to update the reference date for North American Industry Classification System codes from existing law to January 1, 2026, for determining which facilities qualify as emissions-intensive, trade-exposed (EITE) under Washington's cap-and-invest program

Requires the Department of Ecology to provide recommendations to the legislature by December 1, 2026, on allowance allocation schedules for EITE facilities from 2035 through 2050, including methods for annual reductions, criteria for adjustments, and design of consignment-to-auction policies

Establishes new reporting requirements for EITE facilities starting March 31, 2028, requiring biennial emissions data broken down by source type (low/medium/high-temperature heat, industrial processes, electricity) and quadrennial decarbonization plans with best available technology assessments

Creates a framework allowing EITE facilities to receive additional no-cost allowances for production increases, particularly for aerospace manufacturers (NAICS code 3364) using mass-based baselines

Provides that if the legislature does not adopt a new allowance schedule by December 1, 2027, EITE facilities will continue receiving allowances at 2031-2034 levels until a new schedule is established
