Sites recommended for placement in CERCLIS following completion of a PSA require a PA. Each PA includes a narrative report, a Hazard Ranking System (HRS) PA score, and a reference package. FDEP may also complete Site Inspection Worksheets for certain sites if sufficient sampling data is available in the CERCLA site file. The PA's will be completed by FDEP CERCLA staff.

At times, an Abbreviated Preliminary Assessment (APA) can be prepared to expedite the CERCLA process. An APA approach uses the same information as the conventional PA approach but depends on staff’s professional judgment and past site assessment experience to make decisions at earlier stages of the PA process. A brief APA report and an APA checklist are prepared to meet the CERCLA requirements for PA.
