The Superfund program was designed to be paid for by a tax on chemical and oil companies,  but that tax expired years ago, and the program has been strapped for cash since.    But that has changed in recent months. Last fall, the chemical tax was brought back as part of the massive federal infrastructure bill. And oil tax has returned as part of the Inflation Reduction Act, which was signed today by President Joe Biden.   NJ Spotlight News anchor Briana Vannozzi spoke with Rep. Frank Pallone about the tax's return, and why it matters.
