About this file
This is a Cement Preference Certification form required for the Southwest 96-inch Water Transmission Pipeline Project in Texas. The form mandates that bidders certify their concrete products utilize Portland cement from vendors complying with all applicable state and federal environmental standards, specifically Texas Commission on Environmental Quality (TCEQ) and EPA regulations regarding nitrogen oxide (NOx) emissions. Bidders must demonstrate that cement vendors operate kilns with emissions exceeding the NOx standards established in 30 Texas Administrative Code 117.3110(a)(1)-(4) by specific percentage reductions: 10 percent lower for long wet kilns, 20 percent lower for long dry kilns, 20 percent lower for preheater kilns, and 35 percent lower for preheater-precalciner or precalciner kilns. As of March 9, 2011, the specific NOx emission limits are 3.6 lbs per ton of clinker for wet kilns, 4.1 lbs per ton for dry kilns, 3.0 lbs per ton for preheater kilns, and 1.8 lbs per ton for preheater-precalciner or precalciner kilns.
The certification form requires the bidder's authorized officer to sign and have the document notarized by a Texas Notary Public. This cement preference requirement represents a salient environmental procurement criterion for the project, establishing a preference for concrete products manufactured using cleaner Portland cement production processes. The form establishes compliance verification mechanisms that ensure bidders meet stricter-than-minimum environmental standards for cement production, supporting Texas's air quality objectives while maintaining project specifications for the water transmission pipeline construction.
