The Template is filled in to produce the Performance Assessment Guide for one of the environmental impacts. It contains the following sections each with question prompts: Scope & Applicability, Statement of the Problem, Performance Levels, Level Justifications, Regulatory Environment, Directions for Future Research & Development, Design Integration, and Supporting Documents.
The update in November, 2010 gets rid of the "Performance Level" nomenclature. The Prerequisite, Prescriptive Measures, Quantitative Metric, and Zero Impact are the 4 components of what is now called the Standard Assessment Methodology rather than Levels 1, 2, 3, and 4.
