The MTA NYC Transit circulated an email on November 7, 2016 with an update on the proposed Emergency Ventilation Plant project. 

The proposed project involves the construction of an Emergency Ventilation Plant for the Lexington Avenue Subway Line between the 33rd Street Station and the 42nd Street Station at Grand Central, because it currently does not meet Federal standards. The proposed emergency ventilation plant construction sites are in the Murray Hill Historic District, which offers some measure of protection in regards to vibrations and construction techniques. The proposed emergency ventilation plant sites are below the street bed in the northbound traffic lanes of Park Avenue, with ventilation at the street level.

As part of the scoping process, the MTA NYC Transit met with the public and presented their preliminary ideas for the siting of the proposed Emergency Ventilation Plant. During their meeting with Manhattan Community Board 6 on June 6, 2016 and again at the Public Scoping Meeting on June 16, 2016 they presented the current status of the project’s scope and the attendant engineering, economic and environmental issues for each proposed alternative, any significant adverse impacts which may present themselves for each alternative, as well as potential mitigation measures.

The input the MTA NYC Transit has received to date regarding this proposed project will be included in the record of the project along with NYCT responses to questions and concerns regarding the proposed Emergency Ventilation Plant. Comments, questions and concerns raised during the Draft scoping process will be addressed in the Final Scoping Document for the project.

The Public Comment Period for the Draft Scoping Process was open between May 18 and July 1 of 2016, but the public will have an additional opportunity to comment on this project during the Final Environmental Impact Statement (FEIS) phase of the New York State Environmental Quality Review Act (SEQRA) process, of which the Environmental Impact statements are a part. Below is the most recent schedule regarding the Scoping Document and the overall EIS process for the project.
