2020 Winners

Business Continuity

Kirk McDonald GleasonWinner: Kirk McDonald, 
Vice President Cement Technical Services

Kirk has been the Chair of PCA’s Product Standard and Technology Committee’s Limestone/Harmonization Task Group (LSHTG) for more than a decade. The group leads guidance to state communication teams for all the Departments of Transportation, providing background on changes in ASTM and AASHTO specifications. These teams succeeded in speeding the acceptance of the change to permit portland cements to contain up to 5% limestone. Currently the task group is working to communicate the creation of a lower embodied carbon cement, namely portland-limestone cement (PLC), containing between 5% and 15% limestone content.

Steve WilcoxWinner: Steve Wilcox
Cement Technical Director
Argos USA

Steve has been the Chair of PCA’s Product Standards and Technology for the past 4 years and is very active at ASTM, Chairing Subcommittees ASTM C01.10 on Hydraulic Cements and C09.27 on Slag Cement, and is an influential member of the highly-regarded Joint AASHTO-ASTM Harmonization Task Group. All these activities have been important in ensuring that specifications are revised to respond to the practicalities of the marketplace. Steve has been influential in assuring that the market is prepared to accept changes in cement processes that continue to occur. One success has been the market acceptance in the State of Florida where the specifications now accept bag house dust as inorganic processing additions in cement. Another, and even greater, success was the acceptance of portland-limestone cement by the Florida DOT (among other states).

2013 Winners

Satish Sheth
Vice President, Environmental Affairs, CEMEX USA
Committees: Clean Air Committee, Government Affairs Committee.
Category: Business Continuity

As co-chair of the PCA Clean Air Committee, Sheth coordinated PCA's multi-faceted advocacy efforts to address the near-term clean air challenges of the portland cement national emission standards for hazardous air pollutants (NESHAP) and the commercial and industrial solid waste incinerator (CISWI) rules. During a two-year period, he manages a very complicated, multi-pronged regulatory, legislative and legal advocacy strategy, with multiple concurrent and overlapping actions and time-frames, such as developing regulatory comments while also preparing congressional legislation and testimony. The work on the NESHAP rule was rewarded with a favorable court decision followed by a settlement agreement with EPA which ultimately resulted in a new NESHAP rule with more favorable emission standards and more time for the industry to comply. Efforts to address the CISWI rule resulted in significant improvements to what was a very challenging rule when first finalized by EPA. He has now focused Committee efforts on defending EPA's new NESHAP rule and making a few more improvements to the CISWI rule.
