The following volumes are capacities west of Station 1 that will result fro=
m tie-in construction work slated for the Red Rock expansion. Tie-in assem= blies will be required on both the Mainline and Loopline at stations 1, 2, = and 3. New block and side valve assemblies for new compressor and scrubber= s will be installed on the suction side main and loop lines at each station= . The tie-in will entail blocking (isolating) a line segment within the st= ation yard on the suction side (each line done separately) thus creating a = dead leg back to the next upstream block valve crossover(s). Hence, all of= the flow will be forced into a single line when making tie-in on the adjac= ent pipeline line. The result of forcing all volumes into a single line wi= ll produce greater pressure losses in the operating segment to the existing= compression and reduce throughput due to lower suction pressure and respec= tive horsepower limitations. Discharge piping at the station having tie-in= work will be unchanged regarding valving configurations.
