43 Pa. Code § 3.66
The State Board may approve service purchase contracts for routine maintenance service at armories for ash and trash removal, refuse collection or custodial services. The State Board sends contractor bid proposal forms for the services to be performed during the upcoming fiscal year to the local board in April of each year. These forms are to be completed and signed by at least two contractors and returned to the State Board not later than June 1. These contracts shall be executed with a firm, and cannot be executed with an individual. Upon approval of the service purchase contract a copy will be sent to the local board, with the required number of receiving reports. The number of receiving reports required will depend upon the manner of billing provided for in the contract, that is, monthly, quarterly or annually. Work may not be performed under these service purchase contracts until an approved copy has been received by the local board. Receiving reports for these services will be submitted to the comptroller of the Department.
