UCC Project 2089 (line list H-10)
This is to request passage of an ordinance by the City of laPorte granting
permission to Union Carbide Corporation located at Old Ridgebury Road,
Danbury, CT 06817 and incorporated in the State of New York, to cross, lay,
construct, operate, maintain and inspect two adjacent 16-inch pipelines under
the City of laPorte roads "0" Street, "H" Street and "P" Street at locations
shown on the enclosed drawings A-2204978, A-2204979 and A-2204983. A drawing
which displays the entire route through the City of laPorte, A-2204975, is
also enclosed.
The pipelines, to be constructed in 1984, will convey oxygen and nitrogen gas.

road crossings where uDcased pipe is not permitted. Casings
.hall be installed by boriaa or jacking. It is the owner's
de. ire to ainimite cI.ings Ind therefore heavy wall pipe will be
u.ed in lieu of cIsiaa when permitted. In cases where open
cutting i. performed, traffic will be saintained on the roadway.

~ Adequate and uninterrupted drainage of railroad and vehicular
right-of-ways .hall be ..intained. If. in the course of
construction. it becomes necessary to block a drainage facility.
temporary drainage facilities shall be installed to maintain
adequate drainage. Permanent facilities shall be restored at
the completion of construction. All action taken shall be
approved by the right-of-way owner involved.

corrosion by a cathodic protection system designed in accordance
with the HACE Standard RP-01-69 (latest Rev.) "Recommended
Practices for Control of External Corrosion on Underground or
Submerged Pi ping SysteJllS".
10.2 Test stations will be installed at each casing. foreign line
crossing (when required) and .ini~ 1000 ft. intervals along
the pipeline. Insulating flange sets will be installed at all
locations where the pipeline enters and leaves the ground.
