Building it right the 1st time around makes
it easier for everyone.
Smoother, Cheaper, Safer…
And we can all get on with our
respective business.
Makes good sense.
So, what’s needed to make your design &
construction process
(and CenterPoint’s application/approval process)
go smoother and faster?
Look to your

POLE ATTACHMENT GUIDELINES AND PROCEDURES
APPLICATION/APPROVAL PROCESSING PROCEDURES
1.
Not sooner than 100 days prior to start of construction, but not later than 10 business days in
advance of installation, Requestor submits to CNP a design package consisting of the following
items:


Completed CNP Field Data Sheet For Attachments To CenterPoint Energy Poles
(page 5 of 8 in this Section) specifying:
Proposed above-ground height of attachment for requestor’s cable
Above-ground height of existing electrical facilities (at pole and at mid-span)
Number of existing communications cables
Route map(s) showing poles proposed for contact
CNP’s Pole Attachment Request Form (page 4 of 8 in this Section) is provided for the
Requestor’s convenience.
Requestor’s design must be in accordance with National Electrical Safety Code (NESC)
requirements, CNP’s Pole Attachment Guidelines and Procedures and all applicable local
requirements and regulations.
2.
Within 10 business days of receiving Requestor’s design information, CNP will issue a
Temporary Construction Permit (TCP – page 6 of 8 in this Section) to Requestor, accompanied
by CNP’s Permit/Notice Form For Aerial Construction (page 7 of 8 in this Section).
NOTE 1: Pole rental charges begin immediately upon issuance of TCPs. Requestor’s
application should be submitted as close to time of actual construction as possible.
NOTE 2: CNP may exclude from the TCP any poles it reasonably believes do not comply
wth design standards, or that may otherwise be restricted for use by CNP due to
maintenance, renovation, relocation or other CNP activities.
3.
Upon completion of construction, Requestor or its designated representative notifies CNP by
completing Part 3 of the Permit/Notice Form For Aerial Cable Construction. This form may be
faxed (713-207-4031) or e-mailed ([email protected]).
4.
CNP or its designated 3rd party inspector will conduct post-installation inspections of
Requestor’s as-built construction. Requestor will be direct billed the cost of the inspection.
Inspections will occur automatically 90 days after issuance of TCPs unless Requestor applies
for an extension of the TCP, or notifies CNP of cancellation of proposed construction.
5.
Upon completion of the post-installation inspection, and verification that Requestor’s
attachments have been installed in compliance with design standards specified in Item No. 1
above, CNP will replace the TCP with a Pole Attachment License (PAL – page 8 of 8 in this
Section).
For service drops only, installations will be allowed without prior approval providing the service
drop is an extension of a previously-licensed cable installation, and is reported to CNP at the
time of installation, unless otherwise agreed. The location of new service drop contacts must be
reported on a copy of CNP’s Pole Attachment License, and accompanied by a completed Field
Data Sheet.

GENERAL NOTES:
1.
CNP will determine ownership of poles involved in requests, and will designate authorized CNP
poles on TCP(s).
2.
Installations cannot be made on CNP’s poles where violations of the NESC currently exist
unless new installations can be made to meet clearance requirements. CNP will endeavor to
resolve clearance situations, but cannot guarantee resolution will accommodate Requestor’s
desired construction schedule.
3.
Verbal attachment permission will not be given under any circumstances. In priority situations
CNP may provide Requestor with written interim attachment permission by fax or e-mail.
4.
Where Requestor’s as-built construction does not comply with Requestor’s previously submitted
design standards, Requestor must resolve deficiencies or CNP may correct at Requestor’s
expense.
5.
TCPs issued by CNP are valid for a period of 90 days and may be extended for an additional
90-day period in writing by CNP. Any construction not completed at the end of the 2nd 90-day
period will require Requestor to reapply to CNP for use of the involved CNP poles.

POLE ATTACHMENT GUIDELINES AND PROCEDURES
GENERAL DESIGN GUIDELINES
During the design phase of their aerial cable plant proposed for installation on CNP’s
poles, attaching companies should observe the following general guidelines:
-
Attaching companies’ installations must be restricted to communications facilities; no electrical
systems other than those of CNP can be installed on CNP’s poles.
-
All facilities must be installed in accordance with the National Electrical Safety Code (NESC)
and other laws, rules, municipal ordinances and regulations which apply. The NESC,
published by the Institute of Electrical and Electronics Engineers, Inc., is compiled in a manual
available at most bookstores and material supply houses.
NOTE: If a pre-existing violation is identified, additional cables can be installed only if
the additional cables can meet clearance requirements.
-
Attaching companies cannot overlash additional cables to an already existing cable without first
providing CNP with written notification 30 days in advance of such overlashing. Prior to any
overlashing being made, a pole loading study may be required.
-
To minimize facility adjustments by CNP and the need for attaching companies to relocate their
cables in the future, all communications cables should be designed to conform as closely as
practical with the clearance requirements outlined in COMMUNICATION CONDUCTORS
UNDER 12kV CONSTRUCTION (Page 5 of 15) or COMMUNICATION CONDUCTORS UNDER
35kV CONSTRUCTION (Page 6 of 15) in this section.
For use during their design phase, attaching companies may utilize CNP’s Safety Clearance
Worksheet (sample provided in Section 6). This worksheet is intended to be used in
conjunction with the information contained in the tables shown in Section 2 (pages 5 of 15 and
6 of 15) to calculate the maximum allowable attachment height of the attaching company’s
cables.
-
Poles and cable other than those of CNP cannot be installed on CNP’s property or within
CNP’s rights-of-way without prior approval. Where necessary to gain access to CNP’s poles
on CNP’s property, separate written permission must be obtained.
-
In all situations, prior permission must be obtained from property owners and governmental
entities for use of private property and public road rights-of-way. CNP assumes no
responsibility for securing any such permission that may be required, and attaching companies
should assume no such permission exists based solely on the presence of CNP’s facilities.
Where attaching companies’ installations involve city street, county and/or state road rights-ofway, CNP strongly recommends attaching companies contact (early in their planning process)
the appropriate government office to obtain the necessary permit(s).
Rev. 5/2006
-
Attaching companies must bond their messenger in accordance with the NESC. If an attaching
company chooses to use a separate bond wire down the pole, it must be bonded to the CNP
electrical bond at the base of the pole in accordance with the NESC.
-
Communication cables must be installed on the same side of poles (typically the street side) as
CNP’s neutral and secondary conductors and any existing communication cables. In the
absence of any existing installations on CNP’s poles, communication cables must be installed
on the street side of poles.
-
Communications cables must be installed without the use of extension arms, standoff brackets
or similar hardware (unless otherwise approved in advance by CNP, and specifically
referenced on correspondence accompanying the attaching company’s signed Temporary
Construction Permit or Pole Attachment License).

POLE ATTACHMENT GUIDELINES AND PROCEDURES
GENERAL CONSTRUCTION GUIDELINES
Pre-Construction
Prior to proceeding with their physical installations on CNP’s poles, attaching companies
should ensure they have complied with the following:
-
Their workers (whether employees or contractors) are qualified to go upon CNP’s poles and work
near CNP’s electrical lines.
-
Their design complies with the NESC and CNP’s Pole Attachment Guidelines and Procedures .
-
All necessary permissions (in addition to pole permission) have been obtained.
Actual Construction
At all times during their construction activities on CNP’s poles, attaching companies should
adhere to the following:
-
When installing or maintaining its facilities, the attaching company’s construction crews, whether
employees or contractors, must be able to show evidence of permission, either an original or a copy
of CNP’s Temporary Construction Permit or Pole Attachment License, or some form of written
interim permission, covering its specific construction.
-
To minimize facility adjustments by CNP and the need for attaching companies to relocate its cable
in the future, all communications cables should be installed to conform as closely as practical with
the clearance requirements outlined in COMMUNICATION CONDUCTORS UNDER 12kV
CONSTRUCTION (Page 5 of 15) or COMMUNICATION CONDUCTORS UNDER 35kV
CONSTRUCTION (Page 6 of 15) in this section.
-
Communication cables must be properly guyed and anchored before tensioning. This means
attaching companies must install separate guying and anchoring devices to secure their cables;
joint use of CNP’s guys and anchors is not acceptable.
NOTE: Attaching companies are responsible for the costs of any damages to CNP’s
facilities resulting from improper guying and anchoring.
-
Communication cables attached to CNP’s poles must be properly identified according to the CABLE
IDENTIFICATION GUIDELINES (page 10 of 15) and RECOMMENDED TAGGING INTERVALS
(page 12 of 15) in this section.*
* Attaching companies are referred to the following portions of the NESC:
Part 2 – Safety Rules for the Installation and Maintenance of Overhead Electric Supply and
Communication Lines; Section 22; Subsection 220D – Identification of Overhead Conductors and
Subsection 220E – Identification of Equipment on Supporting Structures .
and
Part 4 – Rules for the Operation of Electric Supply and Communication Lines and Equipment;
Section 41 – Supply and Communication Systems – Rules For Employers; Subsection 411E –
Identification and Location.
At any time during construction, if it becomes apparent the attaching company will require additional
time to complete its installations, the attaching company may request an extension of construction time by
completing Part 2 of PERMIT/NOTICE FORM FOR AERIAL CABLE CONSTRUCTION (page 7 of 8 in
Section 1 – Application/Approval and Section 6 – Sample Forms) and submitting to CNP.
Post-Construction
Upon completion of construction, attaching companies must notify CNP by completing Part 3 of the
PERMIT/NOTICE FORM FOR AERIAL CABLE CONSTRUCTION (page 7 of 8 in Section 1 – Application
/Approval and Section 6 – Sample Forms).
Following notification by the attaching company, a post-installation inspection will be performed as
explained in item 5 (page 1 of 8) of Section 1 – Application/Approval.
