The projects are located at Luminant Generation Company’s Sandow Power Plant Unit 4 near Rockdale, Milam County, Texas. 

Sandow Power Plant Unit 4 improvements were made to meet anticipated National Air Ambient Air Quality Standards (NAAQS) and Maximum Achievable Control Technology (MACT) requirements.

Air Quality Control System (AQCS) equipment upgrades included: relocating two pumps, adding three additional pumps in a three sided shelter on a common slab‐on‐grade, new foundations to support the new columns for the Ambient Air Reheat System, and modifications or new foundations for the ductwork for the ID Fan outlet. RINER provided two borings within the future Ashwater Basin area.
