Aug 30 (Reuters) - Colonial Pipeline Co is

allocating space for Cycle 51 shipments on Line 20, which

carries distillates from Atlanta to Nashville, Tennessee, the

company said in a notice sent to shippers on Friday.

* Committed information will be available on Sept. 3, the

pipeline

operator said.

* The company generally announces allocations when

nominations, or

requests, for space to ship petroleum products on its lines

exceed its ability to meet the five-day lifting cycle.

* The cycles are five-day periods when a sequence of all

in-season

products is pumped.

* Colonial pumps the same sequence of products every five

days.

* Colonial connects U.S. Gulf Coast refineries with markets

across

the southern and eastern United States through more than 5,500

miles (8,850 km) of pipeline, delivering gasoline, diesel, jet

fuel and other refined products.
