ENVIRONMENTAL STEWARDSHIP

Charitable efforts like this foster the idea of caring and compassion, a sentiment that is reflected in the team’s day-to-day
work and is evident in its safety performance. By the end of 2023, Ames Mine had worked over 2.7 million hours – or
more than 4,900 days with ZERO lost-time incidents. “We work round the clock, both top side and bottom,” said Heavy
Equipment Operator Spencer Staudt. “But the main thing is we keep everybody safe.”

One way the crew keeps safe work at the forefront of their daily tasks is by reciting the Guardian Angel Creed at the start
of each shift. Kenny Wyman, daytime safety lead, said the Guardian Angel Creed is as an oath of integrity that helps
everyone on site remember to do the right thing every day.

“When I read the Guardian Angel Creed with the crew every morning, it reinforces the mindset that we work safely here
and that it is important to start the day right,” Wyman said. “The main reason I work safely at Ames Mine is that we are
all fully invested in Martin Marietta’s safety culture.”

Situated along the I-35 corridor, Ames Mine is located in an area that supplies most aggregate products used throughout
Central Iowa. In 2023, the site provided millions of tons of product to its customers. Secondary Plant Operator
Mark Himan, however, believes the site’s production numbers do not stand alone. Rather, they reflect the efforts of the
entire crew, its leadership and many talented people from across the Central Division.

“We work well as a team. We are always striving for excellence, and, first and foremost, we are working safely,” Himan
said. “If you work safely, productivity will follow.”
