A timeline of events in the AIR building demolition saga:

December 2014–The EPA informs New Cumberland City Council that it will no longer monitor city wells, since the contamination from groundwater under the old AIR building on South Chester Street had reached acceptable levels.

January 2015–The city grants developer Ron Cross a demolition permit for the building, with the request that he also submit an asbestos abatement plan. Demolition starts later in the month.

March 2015–Demolition work sends a large cloud of dust through part of town, prompting Mayor Linda McNeil to allege violations of a city ordinance.

April 2015–The state of West Virginia issues a cease-and-desist order and a letter of violation of emission standards after determining that the contractor, Unis Demolition, of Aliquippa, Pa., does not have the requisite asbestos certification.

August 2015–Cross says his contractor is being trained in asbestos removal and he hopes to resume demolition by September.

February 2016–City officials express frustration at the lack of progress and send Cross a certified letter, along with copies of three ordinances, asking for compliance in 30 days. Cross hires a new asbestos contractor, American Contracting Enterprises, of McKees Rocks, Pa.

April 2016–The West Virginia Bureau for Public Health lifts one of its cease-and-desist orders.

June 2016–Cross says removal of the roof, including asbestos-containing transite tiles, should begin in July. Work continues through the summer.

September 2016–City officials learn that the asbestos removal has passed state inspection and the rest of the demolition work can continue. Cross files suit against Unis for breach of contract and fraud.

November 2016–Cross receives a default judgment after Unis fails to respond to the lawsuit.
