Several people have called the PA Department of Community and Economic Development.
DCED pointed us to this document and said rinks are considered indoor recreation facilities.
COVID-19 Guidance for Pennsylvania BusinessesIce rinks are considered "indoor recreation" and can operate at 50% total capacity and outdoor fitness activities should be prioritized over indoor.
From the information section on Gatherings and Events, a group gathering would be a training sessions or sporting event, so 25 participants totale and participants must stay 6 feet apart.
Again, priority is given to non-contact skills and drills in sports. Coaches should be wearing masks.
Rinks, clubs and all organizations with questions would be expected to do due diligence in contacting DCED and Department of Health in getting clarification on these rules, preferably in writing. (It would be great if DVHL could get clarification in general and pass this along to member clubs.)
Again, all clubs and rinks are also expected to have publicly posted (on website) protocols for how positive COVID-19 cases will be handled among players/coaches/parents/officials.
