4. Preliminary Determination of Category

We must preliminarily determine the category of the proceeding. (Rule 7.1(d).) As a preliminary matter, we determine this proceeding is ratesetting. (Rule 1.3(e).) This is based on our ongoing implementation and administration of the RPS Program, particularly as part of the larger procurement process, which impacts respondents' rates. This is consistent with our categorizations of the same or similar work in R.04-04-026, R.06-02-012 and R.06-05-027.
