1979: Challenge and accomplishment

Dear members,

At the Stony Brook Project, foundation construction began in early June,1979. Steel circulating water pipes were encased in rebar during the surnoner. Approxirnately 38% of the project's 18,000 cubic yards of concrete were poured by year end. J  !. , I n '; n s-- 4 si.aiQ t est ps% *% s , Y

announced its decision to classify Stony Brook as an " existing" power plant. The l ~ favorable decision was the welcome culmina-tion of seven long months of intensive staff l ' efforts to demonstrate to the federal govern-ment the crucial role Stany Brook plays in N1N1WEC power supply development. After the five month construction delay, construction activity resumed at a dramatic pace. The current status of the Stony Brook 4 Project is a source of pride to N1N1WEC and a credit to the coristruction workforce. The overall construction progress of the Intermediate and Peaking project was esti-mated at 14% at year end. Despite the construction delay, Stony Brook wdl meet its projected commercial on-line dates. Out of 89 contracts necessary to complete the project, thirteen remain to be awarded

One pipeline originates in the port of New Haven, Co n              ut and another pipeline extends from the port of East Providence, Rhode Island. Dedicated storage capacity and terminalling services are anticipated in New Haven, with alternate capacity in East Providence. The offsite storage capacity will
