If a township within the county is operating a recycling program on the effective date of the plan which substantially conforms with or exceeds the requirements of the recycling program included in the plan, the township may continue to operate its recycling program, and such operation shall constitute, within the township, implementation of the recycling program included in the plan. A township may at any time adopt and implement a recycling program that is more stringent than that required by the county waste management plan.
