Monday on the Inland Journal podcast, we talk with a man who has been involved in the region’s toughest environmental issues over the last four decades. Grant Pfeifer played a role in developing regulations for grass field burning in eastern Washington. He helped implement tougher clean water standards in the Spokane River. And there were others. Now he’s retiring. Find and subscribe to “Inland Journal” in iTunes, NPR One or Google Play or on the Inland Journal page at Spokane Public Radio dot org.
