Which organization handles Leaking Underground Storage Tank (LUST) Phase I Site Reconnaissance?

• A. RCRA Facility Assessment (RFA)
• B. CERCLA Preliminary Assessment (PA)
• C. CERCLA Site Inspection (SI)
• D. MDEQ LUST Phase I Site Reconnaissance

Answer: (D)

The key idea is that LUST Phase I Site Reconnaissance is handled by the state's LUST program, not federal programs. In this context, the organization is the state environmental agency’s LUST unit (MDEQ LUST Phase I Site Reconnaissance). The federal frameworks—RCRA Facility Assessments, CERCLA Preliminary Assessments, and CERCLA Site Inspections—serve different purposes and processes (hazardous waste under RCRA, and Superfund assessments under CERCLA). They don’t conduct the LUST Phase I reconnaissance, which is specifically the state’s program tasked with evaluating leaking underground storage tank sites.
