28 Pa. Code § 1027.13
An EMS agency shall give at least 90 days advance notice to each appropriate regional EMS council, PSAP and chief executive officer of a political subdivision within its service area, as well as the chief executive officer of each political subdivision outside of its service area that relies upon it for service even if not provided on a routine basis, before it discontinues its operations or providing an EMS service out of any location at which it is licensed to provide that service or reducing the days or hours it provides the service. The EMS agency shall also advertise notice of its intent to discontinue operations or a service, or reduce the days or hours it provides the service, in a newspaper of general circulation in its service area at least 90 days in advance of discontinuing its operations or a service, or reducing the days or hours it provides the service, and shall provide the Department with written notice that it has met these responsibilities at least 90 days in advance of taking action. This section does not apply if the Department revokes, suspends or restricts the EMS agency's license under terms that do not afford the EMS agency the opportunity to comply with this section.
