The purchasing guidelines in the Municipal Authorities Act were modified by Act 90 of 2011 to change the thresholds for bidding requirements by Pennsylvania Authorities. Act 90 of 2011 subjected the bidding thresholds to an annual escalator. The results of the annual escalation of the thresholds will be published in the Pennsylvania Bulletin by the Department of Labor and Industry prior to January 1 of each year.

Effective January 1, 2018, the threshold limits were set at:

Public notice and competitive bid (Bid Threshold) – In excess of $20,100
Written or telephone price quotes (Quote Threshold) – In excess of $10,900 but less than $20,100
