I may be off base with the information, but it appears that Atlas Powder Co. first purchased land around 1913? or so and built the factory there, looks like around 1971 the company was in decline and was bought out and totally gone by the early 1990's. It mentions 660 acres of remediated area, but to another company. But, maybe you Jeff can make more sense out of the info below than I could, but sure seems to be in the same area. I would have to say, the "Park" was probably a Industrial type park and not a park as we would think of.

By the turn of the last century, the DuPont Company had taken over Nobel’s patent and gained a monopoly in the U.S. explosives market. In 1913, the DuPont monopoly was broken up into three companies: the Hercules Powder Company, the Atlas Powder Company, and the du Pont de Nemours Powder Company.
Atlas Powder Company immediately purchased land in Reynolds, south of Tamaqua for its plant. In 1971, ICI Americas, Inc. purchased Atlas Powder Company and sold off most of the manufacturing operations in 1973.
ICI Americas repurchased the same Atlas Powder Company assets in 1990 and renamed the facility ICI Explosives USA Inc., in 1992. The explosives manufacturing operations ceased in the mid-1990s.
In 2001, ICI Explosives USA Inc. changed its name to E-One Holdings Inc. and divested this property to a new subsidiary, Expert Management Inc. In December 2002, EMI became a wholly owned subsidiary of ICI Americas Inc., and is no longer associated with E-One Holdings Inc. EMI has been looking to sell the property. The property is currently under remediation.
A 660-acre remediated area has been sold to Copperhead Chemical Company, a manufacturer of nitroglycerin used in the treatment of angina and congestive heart failure and explosive materials for use in propellants, fuel additives, and munitions.
