In July, WESTAR submitted comments to EPA’s non-regulatory docket seeking input on potential revisions to the Regional Haze rule. WESTAR recommended changes to the connection between reasonable progress and Long-term strategies, more efficient ways to evaluate source controls, a clearer role for the Uniform Rate of Progress line and Natural Conditions, and improvements to the modeling and monitoring requirements. WESTAR also recommended that EPA extend the deadline for third-round SIPs by three years to allow time to complete the rule revisions and for states to fully incorporate those revisions into their planning.
