Daybreak Community (Operable Unit 7)

10400 South 4000 West, South Jordan, Utah 84095

Operable Unit 7, South Jordan	The Wasatch Mountains and a portion	Example of homes constructed in

Evaporation Ponds	of the Daybreak Community	Daybreak

Supported Land Uses: According to response actions listed below, the Daybreak community
supports a mix of residential, commercial, light industrial, recreational, and open space uses.

Restricted Use: Developed portions of the Daybreak community have been remediated to the
established residential standards. Kennecott Land Company screens undeveloped portions to assess
compliance with the residential use standards.

Setting:

•	The Daybreak community includes the footprints of
Operable Units 1, 5, 7, and 17 of the Kennecott (South
Zone) Superfund site.

•	The Daybreak community is a 4,500-acre master-planned
community which includes Energy Star certified homes,
restaurants, commercial and light industrial, businesses,
indoor and outdoor recreational opportunities, and
designated open space.

•	Mining activities began in the 1860s and continue at the
open-pit Bingham Canyon Mine.

Remedial Status:

•	From 1994 to 1997, Kennecott Utah Copper Company
(now Kennecott Utah Copper LLC, Kennecott) removed
soils and waste rock with elevated concentrations of
lead and consolidated/capped sediments with elevated
concentrations of sulfate.

•	1998 and 2001, EPA rendered Records of Decision
pertaining to remedial actions in Operable Units 1, 5, 7
and 17 of the Kenneco tt South Zone (whose footprints are
within the boundaries of the Daybreak community).

Disclaimer: EPA does not warrant that the property is suitable for any particular
use. Any prospective purchaser must contact the property owner for sale potential.

Early 2000s, Rio Tinto (parent company of Kennecott)
began planning for the Daybreak community, and in
2001 formed the Kennecott Land Company to pursue
redevelopment of remediated land holdings.

From 2004 to 2006, Kennecott Land Company, EPA
and the State of Utah coordinated the development of
an operation and maintenance plan for the Daybreak
community, which in part specified how the operable unit
footprints in the community could be redeveloped.

From 2006 onward, Kennecott pursued remediation of
soils with concentrations of lead and arsenic above the
established residential land use standards in redevelopment
areas of the community and the removal of previously
capped soils with elevated sulfate concentrations.
