									               FINDING OF NO SIGNIFICANT IMPACT (FNSI)
   Water Distribution and Wastewater Collection Systems Expansion to Unserved
Communities of Lomas del Mar and Santa Cruz within the Municipality of Tijuana, Baja
                               California, Mexico

PROJECT LOCATION AND DESCRIPTION

The U.S. Environmental Protection Agency (EPA) is considering authorizing the award
of a Border Environment Infrastructure Fund (BEIF) grant to the Comisión Estatal de
Servicios Públicos de Tijuana (CESPT), which is the State of Baja utility responsible for
providing water and wastewater service to the municipality of Tijuana and Playas de
Rosarito. Tijuana is located on the northwestern side of the State of Baja California,
Mexico (Figure 1-1), and has an estimated population of 1,590,420 residents.
The proposed project would expand drinking water and wastewater collection service to
the communities of Lomas del Mar and Santa Cruz located in southwestern Tijuana.
These communities are located south of the U.S.-Mexico International Border,
approximately 6 miles (9.6 km) and 9 miles (14.5 km) respectively, and are within the
San Antonio del Mar and Cueros de Venado sub-basins.

PURPOSE AND NEED FOR PROPOSED ACTION

Currently, the communities Lomas del Mar and Santa Cruz rely on hauled water for
drinking water and septic tanks, latrines, and open discharges for wastewater disposal.
The purpose of the proposed action is to address environmental and public health risks
associated with inadequate water distribution, as well as inadequate collection of
wastewater. Water and wastewater service needs to be expanded to these unserved areas
to meet federal and state regulatory requirements. It is estimated that the proposed
project will provide drinking water service to 2,418 residents and wastewater collection
service to 3,568 residents.

The project consists of the installation of approximately 8,858 ft (2700 m) of drinking
water pipelines ranging in diameter from 4 to 6 inches for the community of Lomas del
Mar, and the installation of approximately 22,146 ft (6750 m) of sewer lines of 8 inches
diameter for Lomas del Mar and Santa Cruz. The project also includes the construction of
a lift station to convey the flows from the Santa Cruz to the “Sainz” collector which in
turn conveys wastewater flows to the existing San Antonio de Los Buenos (SAB)
wastewater treatment plant. Wastewater from Lomas del Mar would be treated at the
Tecolote La Gloria wastewater treatment plant, currently under construction.

ENVIRONMENTAL CONSEQUENCES AND CONDITIONS

In compliance with the National Environmental Policy Act, EPA has prepared an
environmental assessment (EA) that examines the potential environmental impacts of the
proposed project in the U.S. After considering a wide range of regulatory, environmental
(both natural and human) and socio-economic factors, the EA did not identify any



                                            1
significant impacts to the environment that would result from the implementation of this
project.


PUBLIC REVIEW

The Environmental Assessment is on file, and is available for public review at the EPA
Region 9 office. In addition, the EA is posted on the EPA website at:
http://www.epa.gov/.

Interested persons, including those who disagree with this proposal, may submit
comments to EPA Region 9 by January 4, 2010. No administrative action will be taken
on this proposed project prior to this date. Comments, via letter fax or email should be
sent to Elizabeth Borowiec at the address listed below:

After EPA assesses any comments received, those comments, EPA’s responses, and this
FNSI will be forwarded to the EPA Regional Administrator for review and signature. If
the Regional Administrator signs this FNSI, it will not be re-circulated for public
comment, but will be available to any individual upon request.
