Don't worry about the "hazardous waste recycler" issue. The EPA considers lead on a range as being used for it's intended purpose, and considers it a "recyclable material", as long as the range is open to use. It only becomes a hazmat issue if the range is closed to use and is no longer a shooting range. Then, and only then, does it become a "hazardous material", unless there are Clean Water Act issues. If that occured, then they'd have bigger issues to address.
What that range needs to do is adopt the "Best Management Practices", as outlined in the Environmental Aspects of Construction and Management of Outdoor Shooting Ranges manual published by the National Shooting Sports Foundation (NSSF), which was written with input from the EPA's Ed Guster III. They would become better stewards of their land, and wouldn't have to worry about regulatory agencies finding fault with their management of the facility. They would also reap profits from the mining of the lead, either in cash, or recycled shot, which can be sold. Either way, they need to address the issue of shot buildup on their range.
Hope this helps.
