What is being done about leaking underground storage tanks and brownfields?

Question

What will be an ideal response?

Answer 1

"Underground storage tank (UST) regulations, part of RCRA, now require strict monitoring of fuel supplies, tanks, and piping so that leaks may be detected early. When leaks are detected, remediation must begin within 72 hours. Rules now require all USTs to be upgraded with interior lining and cathodic protection (to retard electrolytic corrosion of the steel), and new tanks must be provided with the same protection if they are steel."
"Brownfields are ‘abandoned, idled, or underused industrial and commercial facilities where expansion or redevelopment is complicated by real or perceived environmental contamination' (EPA definition). The Brownfield Act in 2002 (passed with bipartisan support) provides grants for the assessment of sites and remediation work and authorized $200 million for the ensuing five years of the program. The brownfields program ‘limits liability for owners and prospective purchasers of contaminated land, thus clearing the way for more cleanup of the estimated 450,000 sites that would qualify as brownfields.' Frequently, the rehabilitation of brownfield sites provides industries and municipalities with centrally located, prime land for facilities that would otherwise have been carved out of suburban or ‘greenfield' land (land occupied by natural ecosystems). A further advantage is that new developments go back on the tax rolls, turning a liability into a community asset that lightens the load of residential taxpayers."
