China Clay Producers Association (CCPA) retained Duffey to help prevent the passage of a severance tax on the Kaolin industry by the Georgia General Assembly.

CCPA worked with Duffey to develop and propose its own tax plan, designed as a "self-policing measure" to prevent more costly state legislative action. In response, Duffey formulated publicity profiles, generated a series of print and electronic news packets, and responded to inaccurate Atlanta Journal-Constitution stories and editorials with CCPA letters to the editor.

Duffey coordinated speaking opportunities at more than 150 key civic and business associations to ignite support for the CCPA-proposed county tax measure and educate influential audiences on the opposition to a state severance tax.

Duffey arranged and coordinated an alliance with the Georgia Mining Association based on both organizations' common interest in opposition to the state severance tax.

In addition, Duffey distributed "call to action" flyers, developed a complete list of Georgia legislators and organized a grassroots bumper sticker campaign. Results were a tremendous success. Governor Zell Miller's tax assessment panel rejected the notion of a severance tax on the Kaolin industry. When compared to the total program budget, the overall publicity generated by Duffey's efforts resulted in a 399 percent return on investment.
