Cut any pipes sticking up down another foot to ground level so they are not a hazard and take care of the other issues which seem minor, but should be taken care of.  It's unfortunate this mine on lands the feds gave to the state for development was stopped from going through the permit process by one EPA employee with a personal environmental agenda, Phil North.  (Unlike Hillary, Phil was smart enough after corrupting the permit process and destroying his emails to flee the United States before he could be charged with multiple felonies for destroying official federal records) Not sure if the mine would have made it through the permitting process but if it did, the $1 billion a year in royalties and taxes to the State would have preserved the full permanent fund dividend payment for all Alaskans and sent another $400 million to the treasury for medicaid, education, and payments to seniors.  Not to mention providing thousands of $100,000 a year jobs for locals with no jobs now.
