Current through June, 2024
(a) All utility
				  installations involving pressure pipelines shall comply with the American
				  National Standards Institute (ANSI) code for pressure piping B31.1, B31.4 and
				  B31.8. Installation for electric and communication systems shall comply with
				  State of Hawaii "Public Utilities Commission's General Order No. 10" (Hawaii
				  Administrative Rules, title 6, chapter
				  70).
(b) All utility installations carrying
				  flammable and combustible products shall meet the requirements of the Part 192,
				  Title 49, Code of Federal Regulations, Minimum Federal Safety Standards for Gas
				  Lines; national fire code; State of Hawaii "Public Utilities Commission's
				  General Order No. 9" (Hawaii Administrative Rules, title 6, chapter 69), and
				  local county and state codes and requirements.
(c) The angle of utility crossing shall be
				  generally normal to the highway and it shall not exceed 45 degress from
				  normal.
(d) Longitudinally,
				  utilities shall be located on uniform alignment as near as practicable to the
				  right-of-way line to provide space for future highway construction and for
				  possible future utility installations consistent with good engineering judgment
				  and economic considerations.
(e) In
				  areas where the transverse slopes are gently rolling, cleared, graded and
				  accessible to equipment, a utility shall be installed outside of the roadway
				  cross-section (pavement, shoulder and cut or fill slopes).
(f) In areas where good engineering judgment
				  and economic considerations indicate that it would not be practical to install
				  the utility outside the roadway cross-section, (pavement, shoulder and cut or
				  fill slopes) such as in high cut and fill sections not accessible to equipment,
				  a utility, subject to the approval of the highway utility encroachment
				  committee may be located within the shoulder and median (of a divided highway)
				  areas as provided below:
(1) Shoulder area.
(A) They shall be located as close to the
				  outer edge of shoulder as possible.
(B) In areas where the width of shoulder is B
				  feet or less, no utility shall be permitted to be located within the shoulder
				  for a distance of 2 feet from the normal edge of pavement to the inner edge of
				  trench. See exhibit "H" attached at the end of this chapter.
(C) In areas where the width of shoulder is
				  more than 8 feet, no utility shall be permitted to be located within the
				  shoulder for a distance of 5 feet from the normal edge of pavement to the inner
				  edge of trench. See exhibit "H" attached at the end of this chapter. In the
				  event all available spaces on both shoulders are occupied, considerations may
				  be given to permit a utility within the 5-foot restricted area provided the
				  2-foot strip as outlined in this chapter is not disturbed.
