NOTICE DATE: February 23, 2022

NOTICE TYPE: M-B022322-01 Operations

SHORT DESCRIPTION: TCEQ Enforcement Discretion Beginning at Midnight Tonight

INTENDED AUDIENCE: QSEs and Resource Entities with Generation Assets

DAYS AFFECTED: February 23, 2022 until further notice

LONG DESCRIPTION: ERCOT anticipates tight grid conditions late this evening through Friday, February 25, 2022. To ensure all possible generation is available to serve system demand, ERCOT has requested that the Texas Commission on Environmental Quality (TCEQ) exercise its enforcement discretion with respect to generator exceedances of TCEQ air permit limitations. TCEQ has communicated to ERCOT that it will use its enforcement discretion in evaluating generation facility exceedances of emission and operational permit limits in order to maximize generation availability during this period of concern.  TCEQ’s enforcement discretion will apply beginning at midnight (12:00 a.m.) tonight.  Unless TCEQ provides notice otherwise, the period of enforcement discretion will continue until ERCOT issues a Market Notice indicating that ERCOT’s request for enforcement discretion has ended.

Any generation facility operator that expects to exceed its air permit limits to assist during this period shall document its activities and provide notice to Kelly Cook (, Deputy Director of Critical Infrastructure Division for TCEQ.
