+  zip_path,
+  target_states = c("Washington", "Georgia"),
+  simplify_tol = 0.05
+)
+}
+\arguments{
+\item{zip_path}{Character string. The file path to the zipped EPA shapefile.}
+
+\item{target_states}{Character vector. The names of the states to clip the
+ecoregions to. Defaults to \code{c("Washington", "Georgia")}.}
+
+\item{simplify_tol}{Numeric. The simplification tolerance passed to
+\code{rmapshaper::ms_simplify}. Range is 0-1, where higher numbers remove more detail.
+Defaults to 0.05.}
+}
+\value{
+An \code{sf} object containing the processed ecoregions with standardized
+columns \code{US_L3NAME} and \code{STATE_NAME}.
+}
+\description{
+Extracts EPA Level III ecoregion data from a zipped shapefile,
+standardizes column names, and clips the geometry to specified state boundaries.
+It includes robust steps for geometry repair (handling spherical validity),
+small island removal, and simplification for optimized plotting.
