Re: Proposed Installation of an Antenna on Pre-Existing Communication Tower
Dear Weld County Commissioners,
U.S. Immigration and Customs Enforcement (ICE), a component agency of the U.S. Department
of Homeland Security, has begun a nationwide system of placing new communications antennae
upon pre-existing communications towers to improve communications among different ICE
offices. When completed, this system will allow ICE to respond to emergent situations more
rapidly, thereby improving national safety and security. In accordance with Section 106 of the
National Historic Preservation Act of 1966, as codified and amended at 16 U.S.C. § 470f, and
the implementing regulation, 36 C.F.R. pt. 800, ICE is required to take into account the effects of
its undertakings upon historic properties, and this requires consulting with local government and
tribal organizations which might be impacted by our undertakings.
ICE proposes to place an antenna upon a pre-existing communications tower on the outskirts of
Greeley, Colorado in Weld County. Detailed information regarding this site and the proposed
action is provided in Exhibit A.
Based upon our delineation of the area potentially affected by our proposed undertaking and our
review of publically available information, our initial assessment is that our undertaking does not
affect historic properties or resources. We recognize, however, that you may have information
that indicates otherwise. As a consulting party, we wish to afford you the opportunity to review
and comment upon the proposed action including substantive input regarding historic resources
within the Area of Potential Effect (APE) as well as the APE's scope. In addition, we recognize
that certain information regarding cultural resources might be sensitive, and that you may not
want to disclose specific information regarding such resources without further discussion
between us.

receipt. Please provide information either by mail, e-mail, or facsimile to:

Technical Project Information
Proposed Site Information:
The proposed site is an existing Federal Communications Commission (FCC) registered
telecommunications tower located in Greeley, Colorado in Weld County.

11981 Weld County
Greeley, CO Rd. 54, Weld Co., 40 22'42.36"N/ 1028025 Free Standing Tower
80620 104 49'57.91"W 89.9-m/295-ft
Proposed Equipment:
The following equipment is proposed for collocation to the existing telecommunications tower:
Antenna Ground Equipment
• One(1)Antenna-Andrew omnidirectional whip • One(1)Transmitter-Motorola Quantar VHF
antenna(18.7-feet tall x 2.5-inches wide at the inside existing compound. Space required is 6'
dipole element, 51 lbs.). long x 6' wide x 8' high.
Technical Review:
• Since the existing aboveground cable trays, tower railings, and equipment compound will
be used for this collocation, no construction or ground disturbance will occur.
• The proposed antenna will be mounted on the tower at 145 feet, resulting in no increase
to the tower's overall height.
• ICE examined the visual impacts to historic properties based on a '/-mile"Area of
Potential Effects" (APE) for a newly introduced visual element to an existing tower with
a height ranging between 200 and 400 feet.1
• There are no sites on the National Register of Historic Places (NRHP) in the vicinity of
the proposed collocation site. The nearest NRHP sites to the northeast, south, southwest,
and northwest of the proposed site are depicted in A-3.
• ICE is unaware of any historic properties eligible for inclusion on the NRHP within the
APE.

1. For purposes of establishing an APE,ICE assessed an APE for visual impacts consistent with the Federal
Communications Commission(FCC),National Programmatic Agreement for Review of Effects on
Historic Properties for Certain Undertakings approved by the Federal Communication Commission,
FCC 04-222 (Sept. 2004).Following the Advisory Council on Historic Preservation's guidance to U.S.
Customs and Border Protection regarding collocation of communications equipment,ICE recognizes that
the programmatic agreement is not applicable to its collocation actions. Letter from Charlene Dwin
Vaughn,Advisory Council on Historic Preservation to Thomas Alexander,U.S. Customs&Border
Protection,U.S. Customs and Border Protection Tactical Communications(TACCOM)Modernization
Program Nationwide(May 11,2010). However, since ICE's actions present similar undertakings in
nature and scope to the FCC-licensed collocations,ICE has assessed an APE for visual impacts
consistent with the programmatic agreement to assist consulting parties with their review of potential
impacts.
