A company reclaiming mineland in Hazleton with dredged material from Fort Mifflin in Philadelphia now has permission to import brick, block and soil from a chemical plant in Philipsburg, N.J.

Hazleton Creek Properties received approval to use demolition material from the Mallinckrodt Baker plant in Phillipsburg on the site of a proposed amphitheater in Hazleton.

The material comes from three buildings razed in September, Hazleton Creek said when asking the state Department of Environmental Protection to approve the new source.

Hazleton Creek has approval to use more than 410,000 cubic yards of construction and demolition material at the site under terms of a general permit that DEP issued statewide.

The permit requires Hazleton Creek notify DEP of new sources of material 10 days in advance, and the company gave notice on Jan. 4.

DEP spokesman Mark Carmon, telephoned on Friday, said the request to use material from Mallinckrodt Baker was approved.

According to papers submitted to DEP, Mallinckrodt Baker took core samples from the buildings, pulverized the concrete and tested the powder for contamination.

Before the tests, the company identified the following nine chemicals that it suspected would have contaminated the buildings: ammonia nitrogen, methanol, n-hexane, ethyl ether, ethyl acetate, acetonitrile, formic acid and herbicides known as 24-D, and 245 TP.
