Appendix A to Part 2 - Guidance for Determining the Acceptable
Construction Area for Auxiliary and Replacement Facilities
These guidelines shall be followed to determine what area may be
used to construct the auxiliary or replacement facility.
Specifically, they address what areas, in addition to the permanent
right-of-way, may be used.
An auxiliary or replacement facility must be within the existing
right-of-way or facility site as specified by § 2.55(a)(1) or §
2.55(b)(1)(ii). Construction activities for the auxiliary or
replacement facility can extend outside the current permanent
right-of-way if they are within the temporary and permanent
right-of-way and associated work spaces authorized for the
construction of the existing installation.
If documentation is not available on the location and width of
the temporary and permanent rights-of-way and associated work
spaces that were used to construct the existing facility, the
company may use the following guidance for the auxiliary
installation or replacement, provided the appropriate easements
have been obtained:
a. Construction should be limited to no more than a 75-foot-wide
right-of-way including the existing permanent right-of-way for
large diameter pipeline (pipe greater than 12 inches in diameter)
to carry out routine construction. Pipeline 12 inches in diameter
and smaller should use no more than a 50-foot-wide
right-of-way.
b. The temporary right-of-way (working side) should be on the
same side that was used in constructing the existing pipeline.
c. A reasonable amount of additional temporary work space on
both sides of roads and interstate highways, railroads, and
significant stream crossings and in side-slope areas is allowed.
The size should be dependent upon site-specific conditions. Typical
work spaces are:
| Item |
Typical extra area
(width/length) |
| Two lane road
(bored) |
25-50 by 100 feet. |
| Four lane road
(bored) |
50 by 100 feet. |
| Major river (wet
cut) |
100 by 200 feet. |
| Intermediate
stream (wet cut) |
50 by 100 feet. |
| Single railroad
track |
25-50 by 100 feet. |
d. The auxiliary or replacement facility must be located within
the permanent right-of-way or, in the case of nonlinear facilities,
the cleared building site. In the case of pipelines this is assumed
to be 50 feet wide and centered over the pipeline unless otherwise
legally specified.
However, use of the above guidelines for work space size is
constrained by the physical evidence in the area. Areas obviously
not cleared during the existing construction, as evidenced by
stands of mature trees, structures, or other features that exceed
the age of the facility being replaced, should not be used for
construction of the auxiliary or replacement facility.
If these guidelines cannot be met, the company should consult
with the Commission's staff to determine if the exemption afforded
by § 2.55 may be used. If the exemption may not be used,
construction authorization must be obtained pursuant to another
regulation under the Natural Gas Act.
