Governor Tom Wolf ordered all “non-life-sustaining” businesses throughout Pennsylvania to physically close their operations by 8 p.m. on March 19, 2020 in response to the COVID-19 pandemic. Enforcement begins at 8:00 a.m., Monday, March 23. With the Order, the Commonwealth issued a list of life-sustaining and non-life-sustaining businesses. Residential and commercial construction were on the list of businesses that must close, absent a waiver from the Order. The Commonwealth’s list is intended to be consistent with the federal Cybersecurity and Infrastructure Security Agency (CISA) Memorandum on Identification of Essential Critical Infrastructure Workers During COVID-19 Response, also released March 19, 2020. For developers and builders who may be in critical stages of construction or who have environmental responsibilities under permits (such as the PAG-02 or individual permit for discharges of stormwater associated with construction activities), an immediate shutdown simply cannot be achieved. So what are you to do?
