N.Y. Comp. Codes R. & Regs. Tit. 16 §§ 720-2.6
The Public Service Commission has determined that it is in the public interest to permit liberal modification of service offerings within the limits authorized by a reseller's certificate of public convenience and necessity. It has also determined that it is in the public interest to permit rates for resale of telephone services to fluctuate freely between the maximum and minimum rates established in filed tariffs. Because good cause for flexibility in service offerings and rates has been shown for this industry, changes in the maximum and minimum rates, except major rate changes as defined by Public Service Law, section 92(2), may become effective immediately upon compliance with the notice provisions of State Administrative Procedure Act, section 202. All companies increasing or decreasing a charge within the applicable maximum and minimum rates or making a service change shall notify affected customers and the commission of the new charge or service change no later than the date the charge is first applied or the date the service change is first implemented.
