Former DuPont exec to take Praxair helm Dennis H. Reilley, 46, has been named president and chief executive officer of in­dustrial gases producer Praxair, effective March 15. He will succeed H. William lichtenberger, 64, as CEO and add the ti­tle of chairman on Lichtenberger's retire­ment in November. lichtenberger, who spent 33 years at Union Carbide, has led Praxair since Carbide spun it off in 1992.

Reilley most recently was an execu­tive vice president and one of two chief operating officers at DuPont. Until just two weeks ago, he had spent his entire 25-year professional career at DuPont. On Feb. 14, DuPont made company outsider Richard R. Goodmanson, 52, its sole COO and announced that Reil­ley was leaving to pursue other inter­

ests (C&EN, Feb. 21, page 5).

"Leaving DuPont was not a decision I took light­ly," Reilley says. "This represents an outstand­ing opportunity for me to work with and help lead a group of highly talented people in making Praxair even more successful. I look forward to meeting our future growth and earnings goals."

In 1999, Praxair had Reilley sales of $4.64 billion, down about 4% from 1998. However, net earnings increased about 4% to $441 mil­lion. The company's goal is "double-digit growth in earnings per share, improving return on capital, and maintaining a

healthy balance sheet," Lichtenberger said when reporting year-end earn­ings in late January.

"We believe our busi­ness and investment strat­egies strike the needed balance to meet these goals," he continued. "I am encouraged by the strong demand we are seeing in our major mar­kets, and that heightens my belief that 2000 will be a good year for Praxair."

Lichtenberger expects Reilley to continue the company's prog­ress in serving customers while improv­ing profitability and "to take it to the next level as we enter the 21st century."

EPA shuts web site, but finds no compromised files An inspection during a five-day shutdown of the Environmental Protection Agen­cy's World Wide Web site showed no ap­parent tampering with EPA's electronic files, according to the agency. In addition, sensitive commercial information, such as trade secrets, remains secure and has not been accessed by hackers, the agen­cy says.

EPA shut down its site on Feb. 17 be­cause of concerns about cyber security. This took place a day af­ter two members of the House of Representa­tives called on EPA to immediately discon­nect from the Internet and stay offline until the agency established adequate computer se­curity. Rep. Thomas Blileyjr. (R-Va.), chair­man of the House Com­merce Committee, and Rep. Fred Upton (R-Mich.), chair­man of the Commerce Subcommittee on Oversight & Investigation, asked EPA to act after General Accounting Of­fice investigators hacked into three of the agency's databases (C&EN, Feb. 14, page 62).

"We're talking not only about data worth hundreds of millions of dollars, but trade secrets and sensitive data that could put our national and economic se­curity at risk," Bliley says of his call for EPA to shut down its Internet site. The Virginia lawmaker has long been con­

cerned about computer security at the agency and accuses Administrator Car­ol M. Browner of "gross mismanage­ment of cyber security" during her sev­en-year tenure at EPA.

During the five days the site was down, computer security specialists checked the integrity of EPA's databases and built new electronic firewalls to keep hackers out, EPA spokeswoman Bonnie Piper explains. Databases were un­

harmed, and investiga­tors determined that no confidential busi­ness information in agency electronic files was accessed through the Internet, she says.

EPA issued a state­ment implying the public spotlight that lawmakers cast on the agency about its cyber

security problems drove it to disconnect from the In­

ternet. 'The decision to temporarily close access to the web site was made after... computer security experts warned that the public attention brought to the agen­cy's potential computer vulnerabilities made EPA a likely target for hackers," the agency said.

Jim Solyst, coleader of the Chemical Manufacturers Association's (CMA) in­formation management and right-to-know team, said on Feb. 17: "Under the circumstances, EPA has no other real alternative than to temporarily shut
