An appli­ca­tion for a per­mit for a new gas dis­tri­b­u­tion sys­tem instal­la­tion shall include evi­dence, when required that a “Cer­tifi­cate of Pub­lic Con­ve­nience and Neces­si­ty” has been issued by the Illi­nois Com­merce Com­mis­sion.  Gas pipelines when per­mit­ted on the rights of way of Coun­ty high­ways shall be con­struct­ed, main­tained, and oper­at­ed in con­for­mance with the Fed­er­al Code of the Office of Pipeline Safe­ty Oper­a­tions, Depart­ment of Trans­porta­tion, Part 192 – Trans­porta­tion of Nat­ur­al and Oth­er Gas by Pipeline.  Min­i­mum Fed­er­al Safe­ty Stan­dards, the Department’s “Stan­dard Spec­i­fi­ca­tions for Road and Bridge Con­struc­tion”, and the reg­u­la­tions con­tained in this policy.

Appli­ca­tions for gas pipeline per­mits shall state the pro­posed pipe size, design, con­struc­tion class, and oper­at­ing pressures.

(A) Par­al­lel Gas Pipelines.  Gas pipelines for trans­mis­sion dis­tri­b­u­tion, and ser­vice may be per­mit­ted par­al­lel to the cen­ter­line of con­ven­tion­al Coun­ty high­ways under the fol­low­ing conditions:

  1. The instal­la­tion shall be locat­ed as near as prac­ti­ca­ble to the right of way line and not more than eight (8) feet (2.4m) from and par­al­lel to the right of way line.
  2. The mate­ri­als, con­struc­tion meth­ods, and oth­er ele­ments are in con­for­mance with the pro­vi­sions of Arti­cle I of this Chap­ter.  Gas pipelines shall have min­i­mum cov­er of thir­ty (30) inch­es (0.8m).

(B) Gas Pipeline Cross­ings.  Gas pipelines for trans­mis­sions, dis­tri­b­u­tion, and ser­vice may be per­mit­ted to cross con­ven­tion­al Coun­ty high­ways under the fol­low­ing conditions:

  1. Instal­la­tion shall cross at or as near as prac­ti­ca­ble to a nine­ty (90) degree angle with the high­way centerline.
  2. Cross­ings over six­ty (60) psig shall be installed by jack­ing or bor­ing with vent­ed encase­ment pro­vid­ed between the ditch lines or toes of slopes of the high­way.  The cross­ing may be installed using, tun­nel­ing with vent­ed encase­ment but only when the instal­la­tion is not pos­si­ble by oth­er means.  The vent­ing of the encase­ment shall extend with­in one (1) foot of the right of way line.  Cross­ings may also be installed by the use of “moles”, “whip augers” or oth­er approved meth­ods which com­press the earth to move the open­ing for pipe.
  3. Instal­la­tion by open trench shall be per­mit­ted only pri­or to road­way con­struc­tion with vent­ed encase­ment pro­vid­ed between ulti­mate ditch lines or toes of slopes.
  4. Encase­ment will not be required for ser­vice cross­ings or oth­ers under six­ty (60) psig.
  5. For instal­la­tions six­ty (60) psig and over encase­ment may also be elim­i­nat­ed under the fol­low­ing conditions: 
    • Extra heavy pipe is used with the under­stand­ing that such omis­sion shall pre­clude future main­te­nance or repair.
    • Cathod­ic pro­tec­tion of the pipe is provided.
  6. The loca­tions of the cross­ing pipe for trans­mis­sion and dis­tri­b­u­tion lines shall be marked at the right of way line with mark­ers that iden­ti­fy the util­i­ty and pro­vide emer­gency tele­phone num­bers.  In urban areas, the mark­ers for trans­mis­sion and dis­tri­b­u­tion lines may be elim­i­nat­ed as pro­vid­ed in cur­rent Fed­er­al regulations.
  7. In built-up or expand­ing areas, fre­quent ser­vice cross­ing should be dis­cour­aged in favor of estab­lish­ing dis­tri­b­u­tion on both sides of the highway.
  8.  Gas pipeline cross­ings shall have a min­i­mum cov­er of thir­ty (30) inch­es (0.8m) at all loca­tions on right of way, includ­ing below design ditch ele­va­tion if ditch is high­er than design elevation.
