When the owner and the Commissioner have reached preliminary agreement on the terms of a plan of action, the Commissioner shall prepare a summary of such terms and the anticipated impact of the plan of action on the current tenants. The owner shall send a copy of the summary to each tenant in the project, and shall post a copy of the summary in each occupied building in the project. The summary shall notify tenants that they have sixty calendar days in which to submit any comments to the Commissioner, who shall take any such comments into account before giving final approval to the plan of action.
